+ *
+ * On supported platforms, this will cause GDB to automatically attach.
+ * The nice thing about this, is you can start stepping through your
+ * code at the precice instruction where the interrupt happened. See
+ * `libc/log/attachdebugger.c` to see how it works.
+ *
+ * If you wish to suppress the auto-GDB behavior, then:
+ *
+ *     export GDB=
+ *
+ * Or alternatively:
+ *
+ *    extern int __isworker;
+ *    __isworker = true;
+ *
+ * Will cause your `SIGQUIT` handler to just print a crash report
+ * instead. This is useful for production software that might be running
+ * in a terminal environment like GNU Screen, but it's not desirable to
+ * have ten worker processes trying to attach GDB at once.

+ * Waits for something to happen on multiple file descriptors at once.
+ *
+ * Warning: XNU has an inconsistency with other platforms. If you have
+ * pollfds with fd≥0 and none of the meaningful events flags are added
+ * e.g. POLLIN then XNU won't check for POLLNVAL. This matters because
+ * one of the use-cases for poll() is quickly checking for open files.
+ *
+ * Note: Polling works best on Windows for sockets. We're able to poll
+ * input on named pipes. But for anything that isn't a socket, or pipe
+ * with POLLIN, (e.g. regular file) then POLLIN/POLLOUT are always set
+ * into revents if they're requested, provided they were opened with a
+ * mode that permits reading and/or writing.
+ *
+ * Note: Windows has a limit of 64 file descriptors and ENOMEM with -1
+ * is returned if that limit is exceeded. In practice the limit is not
+ * this low. For example, pollfds with fd<0 don't count. So the caller
+ * could flip the sign bit with a short timeout, to poll a larger set.
+ *
+ * @param fds[𝑖].fd should be a socket, input pipe, or conosle input
+ *     and if it's a negative number then the entry is ignored
+ * @param fds[𝑖].events flags can have POLLIN, POLLOUT, POLLPRI,
+ *     POLLRDNORM, POLLWRNORM, POLLRDBAND, POLLWRBAND as well as
+ *     POLLERR, POLLHUP, and POLLNVAL although the latter are
+ *     always implied (assuming fd≥0) so they're ignored here
+ * @param timeout_ms if 0 means don't wait and -1 means wait forever
+ * @return number of items fds whose revents field has been set to
+ *     nonzero to describe its events, or 0 if the timeout elapsed,
+ *     or -1 w/ errno
+ * @return fds[𝑖].revents is always zero initializaed and then will
+ *     be populated with POLL{IN,OUT,PRI,HUP,ERR,NVAL} if something

  * Sets resource limit for current process.
  *
- * @param resource can be RLIMIT_{CPU,FSIZE,DATA,STACK,CORE,RSS,etc.}
+ * The following resources are recommended:
+ *
+ * - `RLIMIT_AS` limits the size of the virtual address space. This will
+ *   work on all platforms. It's emulated on XNU and Windows which means
+ *   it won't propagate across execve() currently.
+ *
+ * - `RLIMIT_CPU` causes `SIGXCPU` to be sent to the process when the
+ *   soft limit on CPU time is exceeded, and the process is destroyed
+ *   when the hard limit is exceeded. It works everywhere but Windows
+ *   where it should be possible to poll getrusage() with setitimer()
+ *
+ * - `RLIMIT_FSIZE` causes `SIGXFSZ` to sent to the process when the
+ *   soft limit on file size is exceeded and the process is destroyed
+ *   when the hard limit is exceeded. It works everywhere but Windows
+ *
+ * - `RLIMIT_NPROC` limits the number of simultaneous processes and it
+ *   should work on all platforms except Windows. Please be advised it
+ *   limits the process, with respect to the activities of the user id
+ *   as a whole.
+ *
+ * - `RLIMIT_NOFILE` limits the number of open file descriptors and it
+ *   should work on all platforms except Windows (TODO)
+ *
+ * The rlimit magnums differ for each platform but occupy the interval
+ * zero through `RLIM_NLIMITS`. Usually they're set to `RLIM_INFINITY`
+ * which is `-1` on Linux/Windows, and `LONG_MAX` on BSDs. In any case
+ * they're both very large numbers under the Cosmopolitan unsigned ABI
+ * because struct rlimit uses uint64_t. The special magnum 127 is used
+ * for constant values that aren't supported by the host platform.
+ *
  * @param rlim specifies new resource limit
  * @return 0 on success or -1 w/ errno
  * @see libc/sysv/consts.sh
  * @vforksafe

+ *     CHECK_NE(-1, sigaction(SIGINT, &sa, NULL));
+ *
+ * The following flags are supported across platforms:
+ *
+ * - `SA_SIGINFO`: Causes the `siginfo_t` and `ucontext_t` parameters to
+ *   be passed. This not only gives you more information about the
+ *   signal, but also allows your signal handler to change the CPU
+ *   registers. That's useful for recovering from crashes. If you don't
+ *   use this attribute, then signal delivery will go a little faster.
+ *
+ * - `SA_RESTART`: Enables BSD signal handling semantics. Normally i/o
+ *   entrypoints check for pending signals to deliver. If one gets
+ *   delivered during an i/o call, the normal behavior is to cancel the
+ *   i/o operation and return -1 with EINTR in errno. If you use the
+ *   `SA_RESTART` flag then that behavior changes, so that any function
+ *   that's been annotated with @restartable will not return `EINTR` and
+ *   will instead resume the i/o operation. This makes coding easier but
+ *   it can be an anti-pattern if not used carefully, since poor usage
+ *   can easily result in latency issues. It also requires one to do
+ *   more work in signal handlers, so special care needs to be given to
+ *   which C library functions are @asyncsignalsafe.
+ *
+ * - `SA_RESETHAND`: Causes signal handler to be single-shot. This means
+ *   that, upon entry of delivery to a signal handler, it's reset to the
+ *   `SIG_DFL` handler automatically. You may use the alias `SA_ONESHOT`
+ *   for this flag, which means the same thing.
+ *
+ * - `SA_NODEFER`: Disables the reentrancy safety check on your signal
+ *   handler. Normally that's a good thing, since for instance if your
+ *   `SIGSEGV` signal handler happens to segfault, you're going to want
+ *   your process to just crash rather than looping endlessly. But in
+ *   some cases it's desirable to use `SA_NODEFER` instead, such as at
+ *   times when you wish to `longjmp()` out of your signal handler and
+ *   back into your program. This is only safe to do across platforms
+ *   for non-crashing signals such as `SIGCHLD` and `SIGINT`. Crash
+ *   handlers should use Xed instead to recover execution, because on
+ *   Windows a `SIGSEGV` or `SIGTRAP` crash handler might happen on a
+ *   separate stack and/or a separate thread. You may use the alias
+ *   `SA_NOMASK` for this flag, which means the same thing.
+ *
+ * - `SA_NOCLDWAIT`: Changes `SIGCHLD` so the zombie is gone and you
+ *   can't call `wait()` anymore; similar but may
+ *   still deliver the SIGCHLD.
+ *
+ * - `SA_NOCLDSTOP`: Lets you set `SIGCHLD` handler that's only notified
+ *   on exit/termination and not notified on `SIGSTOP`, `SIGTSTP`,
+ *   `SIGTTIN`, `SIGTTOU`, or `SIGCONT`.
+ *
+ * Here's an example of the most professional way to handle signals in
+ * an i/o event loop. It's generally a best practice to have signal
+ * handlers do the fewest number of things possible. The trick is to
+ * have your signals work hand-in-glove with the EINTR errno. This
+ * obfuscates the need for having to worry about @asyncsignalsafe.

+ * that they're @restartable and read() is one such function. Here's
+ * some even better news: if you don't install any signal handlers at
+ * all, then your i/o calls will never be interrupted!
+ *

+ *       xed_instruction_length_decode(&xedd, (void *)ctx->uc_mcontext.rip, 15);
+ *       ctx->uc_mcontext.rip += xedd.length;
+ *     }
+ *
+ *     void OnCrash(int sig, struct siginfo *si, struct ucontext *ctx) {
+ *       SkipOverFaultingInstruction(ctx);
+ *       ContinueOnCrash();  // reinstall here in case *rip faults
+ *     }
+ *
+ *     void ContinueOnCrash(void) {
+ *       struct sigaction sa = {.sa_handler = OnSigSegv,
+ *                              .sa_flags = SA_SIGINFO | SA_RESETHAND};
+ *       sigaction(SIGSEGV, &sa, 0);
+ *       sigaction(SIGFPE, &sa, 0);
+ *       sigaction(SIGILL, &sa, 0);
+ *     }
+ *
+ *     int main() {
+ *       ContinueOnCrash();
+ *       // ...
+ *     }
+ *
+ * You may also edit any other CPU registers during the handler. For
+ * example, you can use the above technique so that division by zero
+ * becomes defined to a specific value of your choosing!
+ *
+ * Please note that Xed isn't needed to recover from `SIGTRAP` which can
+ * be raised at any time by embedding `DebugBreak()` or `asm("int3")` in
+ * your program code. Your signal handler will automatically skip over
+ * the interrupt instruction, assuming your signal handler returns.
+ *
+ * The important signals supported across all platforms are:
+ *
+ * - `SIGINT`: When you press Ctrl-C this signal gets broadcasted to
+ *   your process session group. This is the normal way to terminate
+ *   console applications.
+ *
+ * - `SIGQUIT`: When you press CTRL-\ this signal gets broadcasted to
+ *   your process session group. This is the irregular way to kill an
+ *   application in cases where maybe your `SIGINT` handler is broken
+ *   although, Cosmopolitan Libc ShowCrashReports() should program it
+ *   such as to attach a debugger to the process if possible, or else
+ *   show a crash report. Also note that in New Technology you should
+ *   press CTRL+BREAK rather than CTRL+\ to get this signal.
+ *
+ * - `SIGHUP`: This gets sent to your non-daemon processes when you
+ *   close your terminal session.
+ *
+ * - `SIGTERM` is what the `kill` command sends by default. It's the
+ *   choice signal for terminating daemons.
+ *
+ * - `SIGUSR1` and `SIGUSR2` can be anything you want. Their default
+ *   action is to kill the process. By convention `SIGUSR1` is usually
+ *   used by daemons to reload the config file.
+ *
+ * - `SIGCHLD` is sent when a process terminates and it takes a certain
+ *   degree of UNIX mastery to address sanely.
+ *
+ * - `SIGALRM` is invoked by `setitimer()` and `alarm()`. It can be
+ *   useful for interrupting i/o operations like `connect()`.
+ *
+ * - `SIGTRAP`: This happens when an INT3 instruction is encountered.
+ *
+ * - `SIGILL` happens on illegal instructions, e.g. `UD2`.
+ *
+ * - `SIGABRT` happens when you call `abort()`.
+ *
+ * - `SIGFPE` happens when you divide ints by zero, among other things.
+ *
+ * - `SIGSEGV` and `SIGBUS` indicate memory access errors and they have
+ *   inconsistent semantics across platforms like FreeBSD.
+ *
+ * - `SIGWINCH` is sent when your terminal window is resized.
+ *
+ * - `SIGXCPU` and `SIGXFSZ` may be raised if you run out of resources,
+ *   which can happen if your process, or the parent process that
+ *   spawned your process, happened to call `setrlimit()`. Doing this is
+ *   a wonderful idea.

+ * This function is intended for crash reporting. It's designed to be as
+ * unbreakable as possible, so that error messages can always be printed
+ * even when the rest of the runtime is broken. As such, it has continue
+ * on error semantics, doesn't support buffering between invocations and
+ * floating point is not supported. Output is also truncated if the line
+ * gets too long, but care is taken to preserve your newline characters.
+ * Your errno and GetLastError() state will not be clobbered, and ftrace
+ * and other runtime magic won't be invoked, since all the runtime magic
+ * depends on this function.
+ *
+ * Directives:
+ *
+ *     %[FLAGS][WIDTH|*][.[PRECISION|*]][TYPE]SPECIFIER
+ *
+ * Specifiers:
+ *
+ * - `P` pid
+ * - `c` char
+ * - `o` octal
+ * - `b` binary
+ * - `s` string
+ * - `t` symbol
+ * - `p` pointer
+ * - `d` decimal
+ * - `n` newline
+ * - `u` unsigned
+ * - `r` carriage
+ * - `m` strerror
+ * - `G` strsignal
+ * - `X` uppercase
+ * - `T` timestamp
+ * - `x` hexadecimal
+ *
+ * Types:
+ *
+ * - `hhh` bool
+ * - `hh`  char or cp437
+ * - `h`   short or char16_t
+ * - `l`   long or wchar_t
+ * - `ll`  long long
+ *
+ * Flags:
+ *
+ * - `0` zero padding
+ * - `-` flip alignment
+ * - `!` bypass memory safety
+ * - `,` thousands grouping w/ comma
+ * - `'` thousands grouping w/ apostrophe
+ * - `_` thousands grouping w/ underscore
+ * - `+` plus leftpad if positive (aligns w/ negatives)
+ * - ` ` space leftpad if positive (aligns w/ negatives)
+ * - `#` represent value with literal syntax, e.g. 0x, 0b, quotes
+ * - `^` uppercasing w/ towupper() if linked, otherwise toupper()
+ *
+ * Error numbers:
+ *
+ * - `%m` formats error (if strerror_wr if is linked)
+ * - `%m` formats errno number (if strerror_wr isn't linked)
+ * - `% m` formats error with leading space if errno isn't zero
+ * - `%lm` means favor WSAGetLastError() over GetLastError() if linked
+ *
+ * You need to link and load the symbol table before `%t` will work. You
+ * can do that by calling `GetSymbolTable()`. If that hasn't happened it
+ * will print `&hexnumber` instead.

+/**
+ * Classifies file path name.
+ *
+ * For the purposes of this function, we always consider backslash
+ * interchangeable with forward slash, even though the underlying
+ * operating system might not. Therefore, for the sake of clarity,
+ * remaining documentation will only use the forward slash.
+ *
+ * This function behaves the same on all platforms. For instance, this
+ * function will categorize `C:/FOO.BAR` as a DOS path, even if you're
+ * running on UNIX rather than DOS.
+ *
+ * If you wish to check if a pathname is absolute, in a manner that's
+ * inclusive of DOS drive paths, DOS rooted paths, in addition to the
+ * New Technology UNC paths, then you may do the following:
+ *
+ *     if (_classifypath(str) & _PATH_ABS) { ... }
+ *
+ * To check if path is a relative path:
+ *
+ *     if (~_classifypath(str) & _PATH_ABS) { ... }
+ *
+ * Please note the above check includes rooted paths such as `\foo`
+ * which is considered absolute by MSDN and we consider it absolute
+ * although, it's technically relative to the current drive letter.
+ *
+ * Please note that `/foo/bar` is an absolute path on Windows, even
+ * though it's actually a rooted path that's considered relative to
+ * current drive by WIN32.
+ *
+ * @return integer value that's one of following:
+ *     - `0` if non-weird relative path e.g. `c`
+ *     - `_PATH_ABS` if absolute (or rooted dos) path e.g. `/⋯`
+ *     - `_PATH_DOS` if `c:`, `d:foo` i.e. drive-relative path
+ *     - `_PATH_ABS|_PATH_DOS` if proper dos path e.g. `c:/foo`
+ *     - `_PATH_DOS|_PATH_DEV` if dos device path e.g. `nul`, `conin$`
+ *     - `_PATH_ABS|_PATH_WIN` if `//c`, `//?c`, etc.
+ *     - `_PATH_ABS|_PATH_WIN|_PATH_DEV` if `//./⋯`, `//?/⋯`
+ *     - `_PATH_ABS|_PATH_WIN|_PATH_DEV|_PATH_ROOT` if `//.` or `//?`
+ *     - `_PATH_ABS|_PATH_NT` e.g. `\??\\⋯` (undoc. strict backslash)
+ * @see "The Definitive Guide on Win32 to NT Path Conversion", James
+ *     Forshaw, Google Project Zero Blog, 2016-02-29

+/* lgamma_r(x, signgamp)
+ * Reentrant version of the logarithm of the Gamma function
+ * with user provide pointer for the sign of Gamma(x).
+ *
+ * Method:
+ *   1. Argument Reduction for 0 < x <= 8
+ *      Since gamma(1+s)=s*gamma(s), for x in [0,8], we may
+ *      reduce x to a number in [1.5,2.5] by
+ *              lgamma(1+s) = log(s) + lgamma(s)
+ *      for example,
+ *              lgamma(7.3) = log(6.3) + lgamma(6.3)
+ *                          = log(6.3*5.3) + lgamma(5.3)
+ *                          = log(6.3*5.3*4.3*3.3*2.3) + lgamma(2.3)
+ *   2. Polynomial approximation of lgamma around its
+ *      minimun ymin=1.461632144968362245 to maintain monotonicity.
+ *      On [ymin-0.23, ymin+0.27] (i.e., [1.23164,1.73163]), use
+ *              Let z = x-ymin;
+ *              lgamma(x) = -1.214862905358496078218 + z^2*poly(z)
+ *      where
+ *              poly(z) is a 14 degree polynomial.
+ *   2. Rational approximation in the primary interval [2,3]
+ *      We use the following approximation:
+ *              s = x-2.0;
+ *              lgamma(x) = 0.5*s + s*P(s)/Q(s)
+ *      with accuracy
+ *              |P/Q - (lgamma(x)-0.5s)| < 2**-61.71
+ *      Our algorithms are based on the following observation
+ *
+ *                             zeta(2)-1    2    zeta(3)-1    3
+ * lgamma(2+s) = s*(1-Euler) + --------- * s  -  --------- * s  + ...
+ *                                 2                 3
+ *
+ *      where Euler = 0.5771... is the Euler constant, which is very
+ *      close to 0.5.
+ *
+ *   3. For x>=8, we have
+ *      lgamma(x)~(x-0.5)log(x)-x+0.5*log(2pi)+1/(12x)-1/(360x**3)+....
+ *      (better formula:
+ *         lgamma(x)~(x-0.5)*(log(x)-1)-.5*(log(2pi)-1) + ...)
+ *      Let z = 1/x, then we approximation
+ *              f(z) = lgamma(x) - (x-0.5)(log(x)-1)
+ *      by
+ *                                  3       5             11
+ *              w = w0 + w1*z + w2*z  + w3*z  + ... + w6*z
+ *      where
+ *              |w - f(z)| < 2**-58.74
+ *
+ *   4. For negative x, since (G is gamma function)
+ *              -x*G(-x)*G(x) = pi/sin(pi*x),
+ *      we have
+ *              G(x) = pi/(sin(pi*x)*(-x)*G(-x))
+ *      since G(-x) is positive, sign(G(x)) = sign(sin(pi*x)) for x<0
+ *      Hence, for x<0, signgam = sign(sin(pi*x)) and
+ *              lgamma(x) = log(|Gamma(x)|)
+ *                        = log(pi/(|x*sin(pi*x)|)) - lgamma(-x);
+ *      Note: one should avoid compute pi*(-x) directly in the
+ *            computation of sin(pi*(-x)).
+ *
+ *   5. Special Cases
+ *              lgamma(2+s) ~ s*(1-Euler) for tiny s
+ *              lgamma(1) = lgamma(2) = 0
+ *              lgamma(x) ~ -log(|x|) for tiny x
+ *              lgamma(0) = lgamma(neg.integer) = inf and raise divide-by-zero
+ *              lgamma(inf) = inf
+ *              lgamma(-inf) = inf (bug for bug compatible with C99!?)

+  -----------------------  Chunk representations ------------------------
+
+  (The following includes lightly edited explanations by Colin Plumb.)
+
+  The malloc_chunk declaration below is misleading (but accurate and
+  necessary).  It declares a "view" into memory allowing access to
+  necessary fields at known offsets from a given base.
+
+  Chunks of memory are maintained using a `boundary tag' method as
+  originally described by Knuth.  (See the paper by Paul Wilson
+  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+  techniques.)  Sizes of free chunks are stored both in the front of
+  each chunk and at the end.  This makes consolidating fragmented
+  chunks into bigger chunks fast.  The head fields also hold bits
+  representing whether chunks are free or in use.
+
+  Here are some pictures to make it clearer.  They are "exploded" to
+  show that the state of a chunk can be thought of as extending from
+  the high 31 bits of the head field of its header through the
+  prev_foot and PINUSE_BIT bit of the following chunk header.
+
+  A chunk that's in use looks like:
+
+   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

+  Note that since we always merge adjacent free chunks, the chunks
+  adjacent to a free chunk must be in use.
+
+  Given a pointer to a chunk (which can be derived trivially from the
+  payload pointer) we can, in O(1) time, find out whether the adjacent
+  chunks are free, and if so, unlink them from the lists that they
+  are on and merge them with the current chunk.
+
+  Chunks always begin on even word boundaries, so the mem portion
+  (which is returned to the user) is also on an even word boundary, and
+  thus at least double-word aligned.
+
+  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+  chunk size (which is always a multiple of two words), is an in-use
+  bit for the *previous* chunk.  If that bit is *clear*, then the
+  word before the current chunk size contains the previous chunk
+  size, and can be used to find the front of the previous chunk.
+  The very first chunk allocated always has this bit set, preventing
+  access to non-existent (or non-owned) memory. If pinuse is set for
+  any given chunk, then you CANNOT determine the size of the
+  previous chunk, and might even get a memory addressing fault when
+  trying to do so.
+
+  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+  the chunk size redundantly records whether the current chunk is
+  inuse (unless the chunk is mmapped). This redundancy enables usage
+  checks within free and realloc, and reduces indirection when freeing
+  and consolidating chunks.
+
+  Each freshly allocated chunk must have both cinuse and pinuse set.
+  That is, each allocated chunk borders either a previously allocated
+  and still in-use chunk, or the base of its memory arena. This is
+  ensured by making all allocations from the `lowest' part of any
+  found chunk.  Further, no free chunk physically borders another one,
+  so each free chunk is known to be preceded and followed by either
+  inuse chunks or the ends of memory.
+
+  Note that the `foot' of the current chunk is actually represented
+  as the prev_foot of the NEXT chunk. This makes it easier to
+  deal with alignments etc but can be very confusing when trying
+  to extend or adapt this code.
+
+  The exceptions to all this are
+
+     1. The special chunk `top' is the top-most available chunk (i.e.,
+        the one bordering the end of available memory). It is treated
+        specially.  Top is never included in any bin, is used only if
+        no other chunk is available, and is released back to the
+        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
+        the top chunk is treated as larger (and thus less well
+        fitting) than any other available chunk.  The top chunk
+        doesn't update its trailing size field since there is no next
+        contiguous chunk that would have to index off it. However,
+        space is still allocated for it (TOP_FOOT_SIZE) to enable
+        separation or merging when space is extended.
+
+     3. Chunks allocated via mmap, have both cinuse and pinuse bits
+        cleared in their head fields.  Because they are allocated
+        one-by-one, each must carry its own prev_foot field, which is
+        also used to hold the offset this chunk has within its mmapped
+        region, which is needed to preserve alignment. Each mmapped
+        chunk is trailed by the first two fields of a fake next-chunk
+        for sake of usage checks.

+  When chunks are not in use, they are treated as nodes of either
+  lists or trees.
+
+  "Small"  chunks are stored in circular doubly-linked lists, and look
+  like this:
+
+    chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

+
+  Larger chunks are kept in a form of bitwise digital trees (aka

+  free chunks greater than 256 bytes, their size doesn't impose any
+  constraints on user chunk sizes.  Each node looks like:

+
+  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
+  of the same size are arranged in a circularly-linked list, with only
+  the oldest chunk (the next to be used, in our FIFO ordering)
+  actually in the tree.  (Tree members are distinguished by a non-null
+  parent pointer.)  If a chunk with the same size an an existing node
+  is inserted, it is linked off the existing node using pointers that
+  work in the same way as fd/bk pointers of small chunks.
+
+  Each tree contains a power of 2 sized range of chunk sizes (the
+  smallest is 0x100 <= x < 0x180), which is is divided in half at each
+  tree level, with the chunks in the smaller half of the range (0x100
+  <= x < 0x140 for the top nose) in the left subtree and the larger
+  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
+  done by inspecting individual bits.
+
+  Using these rules, each node's left subtree contains all smaller
+  sizes than its right subtree.  However, the node at the root of each
+  subtree has no particular ordering relationship to either.  (The
+  dividing line between the subtree sizes is based on trie relation.)
+  If we remove the last chunk of a given size from the interior of the
+  tree, we need to replace it with a leaf node.  The tree ordering
+  rules permit a node to be replaced by any leaf below it.
+
+  The smallest chunk in a tree (a common operation in a best-fit
+  allocator) can be found by walking a path to the leftmost leaf in
+  the tree.  Unlike a usual binary tree, where we follow left child
+  pointers until we reach a null, here we follow the right child
+  pointer any time the left one is null, until we reach a leaf with
+  both child pointers null. The smallest chunk in the tree will be
+  somewhere along that path.
+
+  The worst case number of steps to add, find, or remove a node is
+  bounded by the number of bits differentiating chunks within
+  bins. Under current bin calculations, this ranges from 6 up to 21
+  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
+  is of course much better.
+
+  ----------------------------- Segments --------------------------------
+
+  Each malloc space may include non-contiguous segments, held in a
+  list headed by an embedded malloc_segment record representing the
+  top-most space. Segments also include flags holding properties of
+  the space. Large chunks that are directly allocated by mmap are not
+  included in this list. They are instead independently created and
+  destroyed without otherwise keeping track of them.
+
+  Segment management mainly comes into play for spaces allocated by
+  MMAP.  Any call to MMAP might or might not return memory that is
+  adjacent to an existing segment.  MORECORE normally contiguously
+  extends the current space, so this space is almost always adjacent,
+  which is simpler and faster to deal with. (This is why MORECORE is
+  used preferentially to MMAP when both are available -- see
+  sys_alloc.)  When allocating using MMAP, we don't use any of the
+  hinting mechanisms (inconsistently) supported in various
+  implementations of unix mmap, or distinguish reserving from
+  committing memory. Instead, we just ask for space, and exploit
+  contiguity when we get it.  It is probably possible to do
+  better than this on some systems, but no general scheme seems
+  to be significantly better.
+
+  Management entails a simpler variant of the consolidation scheme
+  used for chunks to reduce fragmentation -- new adjacent memory is
+  normally prepended or appended to an existing segment. However,
+  there are limitations compared to chunk consolidation that mostly
+  reflect the fact that segment processing is relatively infrequent
+  (occurring only when getting memory from system) and that we
+  don't expect to have huge numbers of segments:
+
+  * Segments are not indexed, so traversal requires linear scans.  (It
+    would be possible to index these, but is not worth the extra
+    overhead and complexity for most programs on most platforms.)
+  * New segments are only appended to old ones when holding top-most
+    memory; if they cannot be prepended to others, they are held in
+    different segments.
+
+  Except for the top-most segment of an mstate, each segment record
+  is kept at the tail of its segment. Segments are added by pushing
+  segment records onto the list headed by &mstate.seg for the
+  containing mstate.
+
+  Segment flags control allocation/merge/deallocation policies:
+  * If EXTERN_BIT set, then we did not allocate this segment,
+    and so should not try to deallocate or merge with others.
+    (This currently holds only for the initial segment passed
+    into create_mspace_with_base.)
+  * If USE_MMAP_BIT set, the segment may be merged with
+    other surrounding mmapped segments and trimmed/de-allocated
+    using munmap.
+  * If neither bit is set, then the segment was obtained using
+    MORECORE so can be merged with surrounding MORECORE'd segments
+    and deallocated/trimmed using MORECORE with negative arguments.
+
+  ---------------------------- malloc_state -----------------------------
+
+   A malloc_state holds all of the bookkeeping for a space.
+   The main fields are:
+
+  Top
+    The topmost chunk of the currently active segment. Its size is
+    cached in topsize.  The actual size of topmost space is
+    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+    fenceposts and segment records if necessary when getting more
+    space from the system.  The size at which to autotrim top is
+    cached from mparams in trim_check, except that it is disabled if
+    an autotrim fails.
+
+  Designated victim (dv)
+    This is the preferred chunk for servicing small requests that
+    don't have exact fits.  It is normally the chunk split off most
+    recently to service another small request.  Its size is cached in
+    dvsize. The link fields of this chunk are not maintained since it
+    is not kept in a bin.
+
+  SmallBins
+    An array of bin headers for free chunks.  These bins hold chunks
+    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+    chunks of all the same size, spaced 8 bytes apart.  To simplify
+    use in double-linked lists, each bin header acts as a malloc_chunk
+    pointing to the real first node, if it exists (else pointing to
+    itself).  This avoids special-casing for headers.  But to avoid
+    waste, we allocate only the fd/bk pointers of bins, and then use
+    repositioning tricks to treat these as the fields of a chunk.
+
+  TreeBins
+    Treebins are pointers to the roots of trees holding a range of
+    sizes. There are 2 equally spaced treebins for each power of two
+    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+    larger.
+
+  Bin maps
+    There is one bit map for small bins ("smallmap") and one for
+    treebins ("treemap).  Each bin sets its bit when non-empty, and
+    clears the bit when empty.  Bit operations are then used to avoid
+    bin-by-bin searching -- nearly all "search" is done without ever
+    looking at bins that won't be selected.  The bit maps
+    conservatively use 32 bits per map word, even if on 64bit system.
+    For a good description of some of the bit-based techniques used
+    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+    supplement at http://hackersdelight.org/). Many of these are
+    intended to reduce the branchiness of paths through malloc etc, as
+    well as to reduce the number of memory locations read or written.
+
+  Segments
+    A list of segments headed by an embedded malloc_segment record
+    representing the initial space.
+
+  Address check support
+    The least_addr field is the least address ever obtained from
+    MORECORE or MMAP. Attempted frees and reallocs of any address less
+    than this are trapped (unless INSECURE is defined).
+
+  Magic tag
+    A cross-check field that should always hold same value as mparams.magic.
+
+  Max allowed footprint
+    The maximum allowed bytes to allocate from system (zero means no limit)
+
+  Flags
+    Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+  Statistics
+    Each space keeps track of current and maximum system memory
+    obtained via MORECORE or MMAP.
+
+  Trim support
+    Fields holding the amount of unused topmost memory that should trigger
+    trimming, and a counter to force periodic scanning to release unused
+    non-topmost segments.
+
+  Locking
+    If USE_LOCKS is defined, the "mutex" lock is acquired and released
+    around every public call using this mspace.
+
+  Extension support
+    A void* pointer and a size_t field that can be used to help implement
+    extensions to this malloc.

 LOCAL CHANGES
 
-  Numerous local changes were made while vendoring Doug Lee's original
-  dlmalloc sources. Those changes basically boil down to:
-
-    1. Fewer #ifdefs
-    2. More modules (so linker can do a better job)
-    3. Delete code we don't need (cf. Knight Capital)
-    4. Readability / stylistic consistency
-
-  Since we haven't made any genuine improvements to Doug Lee's legendary
-  allocator, we feel this folder faithfully presents his intended work, in
-  harmony with Cosmopolitan conventions.
-
-  The only deleted code we're sure has compelling merit is the mspace
-  functionality. If we ever need memory pools, they might be more
-  appropriately vendored under //third_party/dlmalloc_mspace.
+  - Introduce __oom_hook()
+  - Favor pause (rather than sched_yield) for spin locks

- * independent_calloc(size_t n_elements, size_t element_size, void* chunks[]);
- *
- * independent_calloc is similar to calloc, but instead of returning a
- * single cleared space, it returns an array of pointers to n_elements
- * independent elements that can hold contents of size elem_size, each
- * of which starts out cleared, and can be independently freed,
- * realloc'ed etc. The elements are guaranteed to be adjacently
- * allocated (this is not guaranteed to occur with multiple callocs or
- * mallocs), which may also improve cache locality in some applications.
- *
- * The "chunks" argument is optional (i.e., may be null, which is
- * probably the most typical usage). If it is null, the returned array
- * is itself dynamically allocated and should also be freed when it is
- * no longer needed. Otherwise, the chunks array must be of at least
- * n_elements in length. It is filled in with the pointers to the
- * chunks.
- *
- * In either case, independent_calloc returns this pointer array, or
- * null if the allocation failed. * If n_elements is zero and "chunks"
- * is null, it returns a chunk representing an array with zero elements
- * (which should be freed if not wanted).
- *
- * Each element must be freed when it is no longer needed. This can be
- * done all at once using bulk_free.
- *
- * independent_calloc simplifies and speeds up implementations of many
- * kinds of pools. * It may also be useful when constructing large data
- * structures that initially have a fixed number of fixed-sized nodes,
- * but the number is not known at compile time, and some of the nodes
- * may later need to be freed. For example:
- *
- *     struct Node { int item; struct Node* next; };
- *     struct Node* build_list() {
- *       struct Node **pool;
- *       int n = read_number_of_nodes_needed();
- *       if (n <= 0) return 0;
- *       pool = (struct Node**)(independent_calloc(n, sizeof(struct Node), 0);
- *       if (pool == 0) __die();
- *       // organize into a linked list...
- *       struct Node* first = pool[0];
- *       for (i = 0; i < n-1; ++i)
- *       pool[i]->next = pool[i+1];
- *       free(pool); * // Can now free the array (or not, if it is needed later)
- *       return first;
- *     }

- * independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]);
- *
- * independent_comalloc allocates, all at once, a set of n_elements
- * chunks with sizes indicated in the "sizes" array. It returns an array
- * of pointers to these elements, each of which can be independently
- * freed, realloc'ed etc. The elements are guaranteed to be adjacently
- * allocated (this is not guaranteed to occur with multiple callocs or
- * mallocs), which may also improve cache locality in some applications.

- * The "chunks" argument is optional (i.e., may be null). If it is null
- * the returned array is itself dynamically allocated and should also
- * be freed when it is no longer needed. Otherwise, the chunks array
- * must be of at least n_elements in length. It is filled in with the
- * pointers to the chunks.
- *
- * In either case, independent_comalloc returns this pointer array, or
- * null if the allocation failed.  If n_elements is zero and chunks is
- * null, it returns a chunk representing an array with zero elements
- * (which should be freed if not wanted).
- *
- * Each element must be freed when it is no longer needed. This can be
- * done all at once using bulk_free.
- *
- * independent_comallac differs from independent_calloc in that each
- * element may have a different size, and also that it does not
- * automatically clear elements.
- *
- * independent_comalloc can be used to speed up allocation in cases
- * where several structs or objects must always be allocated at the
- * same time.  For example:
- *
- *     struct Head { ... }
- *     struct Foot { ... }
- *     void send_message(char* msg) {
- *       int msglen = strlen(msg);
- *       size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };
- *       void* chunks[3];
- *       if (independent_comalloc(3, sizes, chunks) == 0) __die();
- *       struct Head* head = (struct Head*)(chunks[0]);
- *       char*        body = (char*)(chunks[1]);
- *       struct Foot* foot = (struct Foot*)(chunks[2]);
- *       // ...
- *     }
- *
- * In general though, independent_comalloc is worth using only for
- * larger values of n_elements. For small values, you probably won't
- * detect enough difference from series of malloc calls to bother.
- *
- * Overuse of independent_comalloc can increase overall memory usage,
- * since it cannot reuse existing noncontiguous small chunks that might
- * be available for some of the elements.

+  When locks are defined, there is one global lock, plus

+  mparams values are initialized only once. It also protects
+  sequences of calls to MORECORE.  In many cases sys_alloc requires
+  two calls, that should not be interleaved with calls by other
+  threads.  This does not protect against direct calls to MORECORE
+  by other threads not using this lock, so there is still code to
+  cope the best we can on interference.
+
+  Per-mspace locks surround calls to malloc, free, etc.
+  By default, locks are simple non-reentrant mutexes.
+
+  Because lock-protected regions generally have bounded times, it is
+  OK to use the supplied simple spinlocks. Spinlocks are likely to
+  improve performance for lightly contended applications, but worsen
+  performance under heavy contention.
+
+  If USE_LOCKS is > 1, the definitions of lock routines here are
+  bypassed, in which case you will need to define the type MLOCK_T,
+  and at least INITIAL_LOCK, DESTROY_LOCK, ACQUIRE_LOCK, RELEASE_LOCK

+  For security, the main invariant is that malloc/free/etc never
+  writes to a static address other than malloc_state, unless static
+  malloc_state itself has been corrupted, which cannot occur via
+  malloc (because of these checks). In essence this means that we
+  believe all pointers, sizes, maps etc held in malloc_state, but
+  check all of those linked or offsetted from other embedded data
+  structures.  These checks are interspersed with main code in a way
+  that tends to minimize their run-time cost.
+
+  When FOOTERS is defined, in addition to range checking, we also
+  verify footer fields of inuse chunks, which can be used guarantee
+  that the mstate controlling malloc/free is intact.  This is a
+  streamlined version of the approach described by William Robertson
+  et al in "Run-time Detection of Heap-based Overflows" LISA'03
+  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
+  of an inuse chunk holds the xor of its mstate and a random seed,
+  that is checked upon calls to free() and realloc().  This is
+  (probabalistically) unguessable from outside the program, but can be
+  computed by any code successfully malloc'ing any chunk, so does not
+  itself provide protection against code that has already broken
+  security through some other means.  Unlike Robertson et al, we
+  always dynamically check addresses of all offset chunks (previous,
+  next, etc). This turns out to be cheaper than relying on hashes.

+  independent_calloc(size_t n_elements, size_t element_size, void* chunks[]);
+
+  independent_calloc is similar to calloc, but instead of returning a
+  single cleared space, it returns an array of pointers to n_elements
+  independent elements that can hold contents of size elem_size, each
+  of which starts out cleared, and can be independently freed,
+  realloc'ed etc. The elements are guaranteed to be adjacently
+  allocated (this is not guaranteed to occur with multiple callocs or
+  mallocs), which may also improve cache locality in some
+  applications.
+
+  The "chunks" argument is optional (i.e., may be null, which is
+  probably the most typical usage). If it is null, the returned array
+  is itself dynamically allocated and should also be freed when it is
+  no longer needed. Otherwise, the chunks array must be of at least
+  n_elements in length. It is filled in with the pointers to the
+  chunks.
+
+  In either case, independent_calloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and "chunks"
+  is null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be freed when it is no longer needed. This can be
+  done all at once using bulk_free.
+
+  independent_calloc simplifies and speeds up implementations of many
+  kinds of pools.  It may also be useful when constructing large data
+  structures that initially have a fixed number of fixed-sized nodes,
+  but the number is not known at compile time, and some of the nodes
+  may later need to be freed. For example:
+
+  struct Node { int item; struct Node* next; };
+
+  struct Node* build_list() {
+    struct Node** pool;
+    int n = read_number_of_nodes_needed();
+    if (n <= 0) return 0;
+    pool = (struct Node**)(independent_calloc(n, sizeof(struct Node), 0);
+    if (pool == 0) die();
+    // organize into a linked list...
+    struct Node* first = pool[0];
+    for (i = 0; i < n-1; ++i)

+
+  independent_comalloc allocates, all at once, a set of n_elements
+  chunks with sizes indicated in the "sizes" array.    It returns
+  an array of pointers to these elements, each of which can be
+  independently freed, realloc'ed etc. The elements are guaranteed to
+  be adjacently allocated (this is not guaranteed to occur with
+  multiple callocs or mallocs), which may also improve cache locality
+  in some applications.
+
+  The "chunks" argument is optional (i.e., may be null). If it is null
+  the returned array is itself dynamically allocated and should also
+  be freed when it is no longer needed. Otherwise, the chunks array
+  must be of at least n_elements in length. It is filled in with the
+  pointers to the chunks.
+
+  In either case, independent_comalloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and chunks is
+  null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be freed when it is no longer needed. This can be
+  done all at once using bulk_free.
+
+  independent_comallac differs from independent_calloc in that each
+  element may have a different size, and also that it does not
+  automatically clear elements.
+
+  independent_comalloc can be used to speed up allocation in cases
+  where several structs or objects must always be allocated at the
+  same time.  For example:
+
+  struct Head { ... }
+  struct Foot { ... }
+
+  void send_message(char* msg) {
+    int msglen = strlen(msg);
+    size_t sizes[3] = { sizeof(struct Head), msglen, sizeof(struct Foot) };
+    void* chunks[3];
+    if (independent_comalloc(3, sizes, chunks) == 0)
+      die();
+    struct Head* head = (struct Head*)(chunks[0]);
+    char*        body = (char*)(chunks[1]);
+    struct Foot* foot = (struct Foot*)(chunks[2]);
+    // ...
+  }
+
+  In general though, independent_comalloc is worth using only for
+  larger values of n_elements. For small values, you probably won't
+  detect enough difference from series of malloc calls to bother.
+
+  Overuse of independent_comalloc can increase overall memory usage,
+  since it cannot reuse existing noncontiguous small chunks that
+  might be available for some of the elements.

-  When locks are defined, there is one global lock, plus

-  two calls, that should not be interleaved with calls by other
-  threads.  This does not protect against direct calls to MORECORE
-  by other threads not using this lock, so there is still code to

-  (The following includes lightly edited explanations by Colin Plumb.)
-
-  The MallocChunk declaration below is misleading (but accurate and
-  necessary).  It declares a "view" into memory allowing access to
-  necessary fields at known offsets from a given base.
-
-  Chunks of memory are maintained using a `boundary tag' method as
-  originally described by Knuth.  (See the paper by Paul Wilson
-  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
-  techniques.)  Sizes of free chunks are stored both in the front of
-  each chunk and at the end.  This makes consolidating fragmented
-  chunks into bigger chunks fast.  The head fields also hold bits
-  representing whether chunks are free or in use.
-
-  Here are some pictures to make it clearer.  They are "exploded" to
-  show that the state of a chunk can be thought of as extending from
-  the high 31 bits of the head field of its header through the
-  prev_foot and PINUSE_BIT bit of the following chunk header.
-
-  A chunk that's in use looks like:
-
-    chunk→ ┌───────────────────────────────────────────────────────────────┐

-  Note that since we always merge adjacent free chunks, the chunks
-  adjacent to a free chunk must be in use.
-
-  Given a pointer to a chunk (which can be derived trivially from the
-  payload pointer) we can, in O(1) time, find out whether the adjacent
-  chunks are free, and if so, unlink them from the lists that they
-  are on and merge them with the current chunk.
-
-  Chunks always begin on even word boundaries, so the mem portion
-  (which is returned to the user) is also on an even word boundary, and
-  thus at least double-word aligned.
-
-  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
-  chunk size (which is always a multiple of two words), is an in-use
-  bit for the *previous* chunk.  If that bit is *clear*, then the
-  word before the current chunk size contains the previous chunk
-  size, and can be used to find the front of the previous chunk.
-  The very first chunk allocated always has this bit set, preventing
-  access to non-existent (or non-owned) memory. If pinuse is set for
-  any given chunk, then you CANNOT determine the size of the
-  previous chunk, and might even get a memory addressing fault when
-  trying to do so.
-
-  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
-  the chunk size redundantly records whether the current chunk is
-  inuse (unless the chunk is mmapped). This redundancy enables usage
-  checks within free and realloc, and reduces indirection when freeing
-  and consolidating chunks.
-
-  Each freshly allocated chunk must have both cinuse and pinuse set.
-  That is, each allocated chunk borders either a previously allocated
-  and still in-use chunk, or the base of its memory arena. This is
-  ensured by making all allocations from the `lowest' part of any
-  found chunk.  Further, no free chunk physically borders another one,
-  so each free chunk is known to be preceded and followed by either
-  inuse chunks or the ends of memory.
-
-  Note that the `foot' of the current chunk is actually represented
-  as the prev_foot of the NEXT chunk. This makes it easier to
-  deal with alignments etc but can be very confusing when trying
-  to extend or adapt this code.
-
-  The exceptions to all this are
-
-     1. The special chunk `top' is the top-most available chunk (i.e.,
-        the one bordering the end of available memory). It is treated
-        specially.  Top is never included in any bin, is used only if
-        no other chunk is available, and is released back to the
-        system if it is very large (see M_TRIM_THRESHOLD).  In effect,
-        the top chunk is treated as larger (and thus less well
-        fitting) than any other available chunk.  The top chunk
-        doesn't update its trailing size field since there is no next
-        contiguous chunk that would have to index off it. However,
-        space is still allocated for it (TOP_FOOT_SIZE) to enable
-        separation or merging when space is extended.
-
-     3. Chunks allocated via mmap, have both cinuse and pinuse bits
-        cleared in their head fields.  Because they are allocated
-        one-by-one, each must carry its own prev_foot field, which is
-        also used to hold the offset this chunk has within its mmapped
-        region, which is needed to preserve alignment. Each mmapped
-        chunk is trailed by the first two fields of a fake next-chunk
-        for sake of usage checks.

-
-  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
-  of the same size are arranged in a circularly-linked list, with only
-  the oldest chunk (the next to be used, in our FIFO ordering)
-  actually in the tree.  (Tree members are distinguished by a non-null
-  parent pointer.)  If a chunk with the same size an an existing node
-  is inserted, it is linked off the existing node using pointers that
-  work in the same way as fd/bk pointers of small chunks.
-
-  Each tree contains a power of 2 sized range of chunk sizes (the
-  smallest is 0x100 <= x < 0x180), which is is divided in half at each
-  tree level, with the chunks in the smaller half of the range (0x100
-  <= x < 0x140 for the top nose) in the left subtree and the larger
-  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
-  done by inspecting individual bits.
-
-  Using these rules, each node's left subtree contains all smaller
-  sizes than its right subtree.  However, the node at the root of each
-  subtree has no particular ordering relationship to either.  (The
-  dividing line between the subtree sizes is based on trie relation.)
-  If we remove the last chunk of a given size from the interior of the
-  tree, we need to replace it with a leaf node.  The tree ordering
-  rules permit a node to be replaced by any leaf below it.
-
-  The smallest chunk in a tree (a common operation in a best-fit
-  allocator) can be found by walking a path to the leftmost leaf in
-  the tree.  Unlike a usual binary tree, where we follow left child
-  pointers until we reach a null, here we follow the right child
-  pointer any time the left one is null, until we reach a leaf with
-  both child pointers null. The smallest chunk in the tree will be
-  somewhere along that path.
-
-  The worst case number of steps to add, find, or remove a node is
-  bounded by the number of bits differentiating chunks within
-  bins. Under current bin calculations, this ranges from 6 up to 21
-  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
-  is of course much better.

-
-/*
-  Each malloc space may include non-contiguous segments, held in a list
-  headed by an embedded MallocSegment record representing the top-most
-  space. Segments also include flags holding properties of the space.
-  Large chunks that are directly allocated by mmap are not included in
-  this list. They are instead independently created and destroyed
-  without otherwise keeping track of them.
-
-  Segment management mainly comes into play for spaces allocated by
-  MMAP. Any call to MMAP might or might not return memory that is
-  adjacent to an existing segment. MORECORE normally contiguously
-  extends the current space, so this space is almost always adjacent,
-  which is simpler and faster to deal with. (This is why MORECORE is
-  used preferentially to MMAP when both are available -- see sys_alloc.)
-  When allocating using MMAP, we don't use any of the hinting mechanisms
-  (inconsistently) supported in various implementations of unix mmap, or
-  distinguish reserving from committing memory. Instead, we just ask for
-  space, and exploit contiguity when we get it. It is probably possible
-  to do better than this on some systems, but no general scheme seems to
-  be significantly better.
-
-  Management entails a simpler variant of the consolidation scheme used
-  for chunks to reduce fragmentation -- new adjacent memory is normally
-  prepended or appended to an existing segment. However, there are
-  limitations compared to chunk consolidation that mostly reflect the
-  fact that segment processing is relatively infrequent (occurring only
-  when getting memory from system) and that we don't expect to have huge
-  numbers of segments:
-
-  * Segments are not indexed, so traversal requires linear scans. (It
-    would be possible to index these, but is not worth the extra
-    overhead and complexity for most programs on most platforms.)
-  * New segments are only appended to old ones when holding top-most
-    memory; if they cannot be prepended to others, they are held in
-    different segments.
-
-  Except for the top-most segment of an mstate, each segment record is
-  kept at the tail of its segment. Segments are added by pushing segment
-  records onto the list headed by &mstate.seg for the containing mstate.
-
-  Segment flags control allocation/merge/deallocation policies:
-  * If EXTERN_BIT set, then we did not allocate this segment,
-    and so should not try to deallocate or merge with others.
-    (This currently holds only for the initial segment passed
-    into create_mspace_with_base.)
-  * If USE_MMAP_BIT set, the segment may be merged with
-    other surrounding mmapped segments and trimmed/de-allocated
-    using munmap.
-  * If neither bit is set, then the segment was obtained using
-    MORECORE so can be merged with surrounding MORECORE'd segments
-    and deallocated/trimmed using MORECORE with negative arguments.

-   A MallocState holds all of the bookkeeping for a space.
-   The main fields are:
-
-  Top
-    The topmost chunk of the currently active segment. Its size is
-    cached in topsize.  The actual size of topmost space is
-    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
-    fenceposts and segment records if necessary when getting more
-    space from the system.  The size at which to autotrim top is
-    cached from mparams in trim_check, except that it is disabled if
-    an autotrim fails.
-
-  Designated victim (dv)
-    This is the preferred chunk for servicing small requests that
-    don't have exact fits.  It is normally the chunk split off most
-    recently to service another small request.  Its size is cached in
-    dvsize. The link fields of this chunk are not maintained since it
-    is not kept in a bin.
-
-  SmallBins
-    An array of bin headers for free chunks.  These bins hold chunks
-    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
-    chunks of all the same size, spaced 8 bytes apart.  To simplify
-    use in double-linked lists, each bin header acts as a MallocChunk
-    pointing to the real first node, if it exists (else pointing to
-    itself).  This avoids special-casing for headers.  But to avoid
-    waste, we allocate only the fd/bk pointers of bins, and then use
-    repositioning tricks to treat these as the fields of a chunk.
-
-  TreeBins
-    Treebins are pointers to the roots of trees holding a range of
-    sizes. There are 2 equally spaced treebins for each power of two
-    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
-    larger.
-
-  Bin maps
-    There is one bit map for small bins ("smallmap") and one for
-    treebins ("treemap).  Each bin sets its bit when non-empty, and
-    clears the bit when empty.  Bit operations are then used to avoid
-    bin-by-bin searching -- nearly all "search" is done without ever
-    looking at bins that won't be selected.  The bit maps
-    conservatively use 32 bits per map word, even if on 64bit system.
-    For a good description of some of the bit-based techniques used
-    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
-    supplement at http://hackersdelight.org/). Many of these are
-    intended to reduce the branchiness of paths through malloc etc, as
-    well as to reduce the number of memory locations read or written.
-
-  Segments
-    A list of segments headed by an embedded MallocSegment record
-    representing the initial space.
-
-  Address check support
-    The least_addr field is the least address ever obtained from
-    MORECORE or MMAP. Attempted frees and reallocs of any address less
-    than this are trapped (unless INSECURE is defined).
-
-  Magic tag
-    A cross-check field that should always hold same value as mparams.magic.
-
-  Max allowed footprint
-    The maximum allowed bytes to allocate from system (zero means no limit)
-
-  Flags
-    Bits recording whether to use MMAP, locks, or contiguous MORECORE
-
-  Statistics
-    Each space keeps track of current and maximum system memory
-    obtained via MORECORE or MMAP.
-
-  Trim support
-    Fields holding the amount of unused topmost memory that should trigger
-    trimming, and a counter to force periodic scanning to release unused
-    non-topmost segments.
-
-  Locking
-    If USE_LOCKS is defined, the "mutex" lock is acquired and released
-    around every public call using this mspace.
-
-  Extension support
-    A void* pointer and a size_t field that can be used to help implement
-    extensions to this malloc.

-/* ─────────────────────── Runtime Check Support ───────────────────────── */

-/*
-  For security, the main invariant is that malloc/free/etc never
-  writes to a static address other than MallocState, unless static
-  MallocState itself has been corrupted, which cannot occur via
-  malloc (because of these checks). In essence this means that we
-  believe all pointers, sizes, maps etc held in MallocState, but
-  check all of those linked or offsetted from other embedded data
-  structures.  These checks are interspersed with main code in a way
-  that tends to minimize their run-time cost.
-
-  When FOOTERS is defined, in addition to range checking, we also
-  verify footer fields of inuse chunks, which can be used guarantee
-  that the mstate controlling malloc/free is intact.  This is a
-  streamlined version of the approach described by William Robertson
-  et al in "Run-time Detection of Heap-based Overflows" LISA'03
-  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
-  of an inuse chunk holds the xor of its mstate and a random seed,
-  that is checked upon calls to free() and realloc().  This is
-  (probabalistically) unguessable from outside the program, but can be
-  computed by any code successfully malloc'ing any chunk, so does not
-  itself provide protection against code that has already broken
-  security through some other means.  Unlike Robertson et al, we
-  always dynamically check addresses of all offset chunks (previous,
-  next, etc). This turns out to be cheaper than relying on hashes.

-  Unlink steps:
-
-  1. If x is a chained node, unlink it from its same-sized fd/bk links
-     and choose its bk node as its replacement.
-  2. If x was the last node of its size, but not a leaf node, it must
-     be replaced with a leaf node (not merely one with an open left or
-     right), to make sure that lefts and rights of descendents
-     correspond properly to bit masks.  We use the rightmost descendent
-     of x.  We could use any other leaf, but this is easy to locate and
-     tends to counteract removal of leftmosts elsewhere, and so keeps
-     paths shorter than minimally guaranteed.  This doesn't loop much
-     because on average a node in a tree is near the bottom.
-  3. If x is the base of a chain (i.e., has parent links) relink
-     x's parent and children to x's replacement (or null if none).

- * number of bytes allocated via malloc (or realloc, etc) but not yet
- * freed. Note that this is the number of bytes allocated, not the
- * number requested. It will be larger than the number requested because
- * of alignment and bookkeeping overhead. Because it includes alignment
- * wastage as being in use, this figure may be greater than zero even
- * when no user-level chunks are allocated.
- *
- * The reported current and maximum system memory can be inaccurate if a
- * program makes other calls to system memory allocation functions
- * (normally sbrk) outside of malloc.
- *
- * malloc_stats prints only the most commonly interesting statistics.

-- zip sometimes crashes on some versions of NetBSD (0.8, 0.9 and early
-  0.9-current), FreeBSD (<= 1.1) and BSDI (< 1.1) . This is due to a
-  bug in stdio.
-  Upgrading the stdio package in /usr/src/lib/libc/stdio should
-  fix the problem. See *BSD mirrors in src/lib/libc/stdio
-  You must at least replace setvbuf.o in all the libc's with a newer version.

-Note:  Zip 2.4 was never released.  That code was the start of the Zip 3.0
-effort below.  Some changes and fixes also made it to the Zip 2.3x releases.
-
----------------------- January 21st 2004 version 3.0a ----------------------
-Initial work on Zip 3.0 by Ed Gordon and Rainer Nausedat
- 1. Changed some comments to update copyrights (Ed)
- 2. Changed text in command line messages from zip 2.4 to zip 3.0 (Ed)
- 3. Changes to many files for Zip64 wrapped in ifdef ZIP64_SUPPORT (Rainer)
- 4. Attempt to fix buggy Win32 buffered 64-bit calls (Ed)
- 5. Add functions to zipfile.c for Little-Endian memory writes (Rainer)
- 6. Add functions to zipfile.c for writing Zip64 extra fields (Rainer)
- 7. Major changes to putlocal, putcentral, and putend (Rainer)
- 8. Fixing -F and -FF for Zip64 postponed (Ed and Rainer)
- 9. Command line code replaced.  Global table sets options, long options now
-    supported.  Permutes so order of arguments can vary (Ed)
-10. Fix bug where not allowed to use -@ with stdout but was with stdin.
-    Now can read filenames from stdin using -@ and output to stdout and
-    no longer am allowed to use -@ if reading from stdin (Ed)
-11. Replace stat() with zstat(), fstat() with zfstat() and struct
-    stat with z_stat in Zip64 blocks.  Put 64-bit file calls in ifdef
-    LARGE_FILE_SUPPORT blocks.  Can implement Zip64 without > 4 GB
-    file support but for now need large files for Zip64 support (Ed)
-12. Move port-specific code to osdep.h and win32.c (port specific) and
-    tailor.h (generic) and remove temporary os_io.c.  As OF() is
-    not defined until after osdep.h includes in tailor.h function
-    prototypes for zfseeko, zftello, and zstat after that in tailor.h (Ed)
-13. Settings of ZIP64_SUPPORT and LARGE_FILE_SUPPORT automatic based on
-    port and version of compiler.  Defining NO_ZIP64_SUPPORT or
-    NO_LARGE_FILE_SUPPORT overrides this (Ed)
-14. Bugs compiling scanzipf_fix(...) in zipfile.c and the fix functions could
-    use rewrite (Rainer and Ed)
-15. Add prototype for zfopen for mapping to 64-bit fopen on ports using
-    inodes but not implemented (Ed)
-16. More work on extended local headers and encypted archives (Rainer)
-17. Fix DLL files so now compiles (Ed)
-18. File size in dll limited to 32-bit in structure.  A new DLL api is needed
-    to return 64-bit file sizes.  Current api fixed to return max 32-bit if
-    more than that (Ed)
-19. Add local header Zip64 support and local extra field.  Fixed cast
-    to ulg missed previously that forced zstat to return value mod 4 GB in
-    zipup.c which kept local header code from seeing actual file size (Ed)
-20. Add new option --force-zip64 to force use of zip64 fields.  Could
-    be temporary (Ed)
-21. Fix for VB added to api.c that just store the passed strings internally.
-    Should update api to optionally return file sizes as 64-bit in call back
-    and to accept RootDir and other strings in same call that zips (Ed)
-22. Readme updated to describe new features and mention updated mail group
-    web links (Ed)
-23. Minor bugs in output format found and fixed.  Now can add
-    files > 4 GB to archive and unzip using major unzippers (Ed)
-24. If zip used as filter (zip - -) and sizes exceed limits of extended
-    local header (data descriptor) then set max 32-bit values there.  Major
-    unzippers ignore and use central directory values which are correct.  Can
-    create Zip64 data descriptor using --force-zip64 option but seems no need
-    for it (Ed)
-25. A few bugs in how headers are handled prevented zipping large numbers
-    of files.  Fixed (Rainer)
-26. A bit of an attempt to fix -F and -FF.  Seems to work but not that
-    robust.  More work needed (Ed)
-27. After some cast and other fixes zip compiles on Linux Red Hat 9 using Unix
-    generic.  Added automatic detection of fseeko64 and if detected
-    sets LARGE_FILE_SUPPORT and setting that sets ZIP64_SUPPORT.  Works but
-    could not test large files on the small system (Ed)
-28. Tried to fix bug that prevents zipnotes from compiling when ZIP64_SUPPORT
-    is set.  Still broke.  This crashes the Unix Makefile but after
-    zip is compiled (Ed)
----------------------- May 8th 2004 version 3.0b ----------------------
- 1. Update license headers on more files (Ed)
- 2. Change many ZIP64_SUPPORT ifdefs to LARGE_FILE_SUPPORT where appropriate.
-    Now can test ports using three stages, compile with NO_LARGE_FILE_SUPPORT
-    (which disables ZIP64_SUPPORT) to test base code, compile with
-    NO_ZIP64_SUPPORT to test the 64-bit file calls (assuming port sets
-    LARGE_FILE_SUPPORT) but otherwise use the base code, and without either
-    to test Zip64 if enabled on port (Ed)
- 3. Fix zipnotes bug by moving a ZIP64_SUPPORT block in zipfile.c (Ed)
- 4. Add Large File Summit (LFS) code to Unix port to enable 64-bit calls.
-    Update configure to include test for all needed 64-bit file calls before
-    enabling LARGE_FILE_SUPPORT for unix port (Ed)
- 5. Merge encryption code from zcrypt29 (files from unzip) into zip and
-    enable by default (Ed)
- 6. New man pages for zipnote, zipsplit, and zipcloak (Greg, Ed)
- 7. Add encryption notice to crypt.c comments and to version information
-    in zip.c (Greg, Ed)
- 8. Add Russian OEM EBCDIC support when OEM_RUSS defined in ebcdic.h but
-    Dmitri reports that 0x2F not '/' so make recommended change in cutpath
-    call in zipfile.c used by -D option (Dmitri - Nov 10 2003 email)
- 9. ToDo30 file added to list what's left to do in this release (Ed)
-10. Change fopen to zfopen for large file code and map to fopen64 for
-    Unix (Ed)
-11. ftello64 seems broken in zipup.c on Linux (kernel 2.4), returning
-    negatives past the 2 GB barrier, though ftello64 works in a test program.
-    Likely error in defines.  For now skip ftello64 check for Unix with
-    LARGE_FILE_SUPPORT.
-12. A few updates in Readme.  Needs overhaul likely.  Also verified mxserver
-    is gone and replaced with list addresses (Ed)
-13. First iterations at updating WinDLL for Zip64 (Mike)
-14. Decide to drop backward dll compatibility in favor of a cleaner
-    dll interface.  Decide to add string interfaces for VB (Ed, Mike)
-15. Add string interfaces to dll interface to bypass array limitations
-    imposed by VB and add -x and -i to interface (Mike)
-16. Create new VB example using new Zip64 dll interface (Ed)
-17. Add O_LARGEFILE define for zopen in unix/zipup.h to enable reading
-    large files in unix (Ed)
-18. Combine ZpSetOptions and ZpArchive dll calls to allow removing all VB kluges
-    in api.c to work around VB garbage collecting passed strings (Mike)
-19. Change new VBz64 example to use updated interface.  All works without
-    kluges (Ed)
----------------------- August 15th 2004 version 3.0c ----------------------
- 1. Add date formats in -t and -tt date errors (Ed)
- 2. Add -so to display all available options (Ed)
- 3. Many fixes from Dan Nelson to fix some large file support problems and
-    add large file support to a few ports.  Main change is rather than use
-    explicit 64-bit calls like fopen64 now set 64-bit environment and use
-    standard calls.  Also add a define for 64-bit printf format used to
-    print 64-bit stats (Dan, Ed)
- 4. Changes to Unix config based on suggestions from Dan Nelson.  Check
-    if off_t is at least 64 bit (Dan, Ed)
- 5. Add -- to get_option.  Any arguments after -- on command line now
-    read as paths and not options (Ed)
- 6. Add extended help (Ed)
- 7. Change add_filter flag parameter from char to int as some compilers have
-    problems with char arguments (Ed)
- 8. Changed filter() to do R and i separately so i has precedence over R (Ed)
- 9. Split variable t in zip.c into t (off_t) and tf (ulg) (Ed)
-10. Add quotes to zipname in check_zipfile for MSDOS to allow spaces in
-    archive path given to unzip to test ( , Ed)
-11. Move zip.h include before ctype.h include in trees.c and zipup.c as
-    when ctype.h is first and using 64-bit environment at least on unix port
-    found it defines off_t as 4 bytes in those files as off_t is defined as
-    8 bytes in other files and this changes the size of the zlist structure
-    which is not good (Ed)
-12. Add default 64-bit file environment to tailor.h if LARGE_FILE_SUPPORT
-    is set but no port 64-bit file defines are set up earlier in the file.
-    Should allow other ports to set LARGE_FILE_SUPPORT on the compiler
-    command line to test if the standard defines work (Ed)
-13. Adjust binary detection in trees.c by changing 20% binary (4 out of 5
-    ascii) that used >> 2 to 2% (64 out of 65) using >> 6 instead.
-    trees.c  (Ed)
----------------------- November 12th 2004 version 3.0d ----------------------
- 1. Add global variable for EncryptionPassword in VBz64 example and
-    some other password callback cleanup (Ed)
- 2. Add -W option to turn on WILD_STOP_AT_DIR where wildcards will not
-    include directory boundaries in matches (Ed)
- 3. Add -nw option "no wild" to completely disable wildcards in MATCH
-    function.  Allows a list of files to be read in without worrying about
-    wildcards or escapes (Ed)
- 4. Add -s option split-size but not implemented (Ed)
- 5. Add -sp option split-pause but not implemented (Ed)
- 6. Add changes for WiZ including moving Win32 64-bit wrappers into
-    win32i64.c to avoid naming conflict between libraries in WiZ (Mike, Ed)
- 7. Some large file fixes in crypt.c (Ed)
- 8. Add new error code ZE_UNSUP for unsupported compiler options.  Add
-    check of size of zoff_t in zip.c when LARGE_FILE_SUPPORT enabled (Ed)
- 9. Changed ZE_UNSUP to ZE_COMPERR to avoid conflict with unzip (Ed)
-10. On VMS (sufficiently recent, non-VAX), DECC$ARGV_PARSE_STYLE is set
-    automatically to preserve case of the command line if the user has
-    SET PROCESS /PARSE = EXTEND.  This obviates quoting upper-case
-    options, like -V, when enabled.  VMS.C (Steven Schweda (SMS))
-11. On VMS, building with macro VMS_PRESERVE_CASE defined preserves case
-    of names in archive, instead of forcing lower-case (the former and
-    current default behavior).  VMSZIP.C (SMS)
-12. On VMS, in some of the simplest cases, ODS5 extended file name
-    escape characters ("^") are removed from names in archive.
-    VMSZIP.C (SMS)
-13. On VMS, fixed a problem in some cases with mixed-case directory
-    names, where too much of the directory hierarchy was included in the
-    path names in the archive.  VMSZIP.C (SMS)
-14. On VMS, minor changes for large file support (long -> zoff_t).
-    VMSZIP.C (SMS)
-15. On VMS, changed some structure declarations to typedefs, and
-    rearranged to simplify #if's and reduce potential name conflicts.
-    VMS.H, VMS_IM.C, VMS_PK.C (SMS)
-16. On VMS, reformed -V (/VMS) processing.  Added -VV (/VMS=ALL).
-    Removed some sign bits to accomodate files bigger than 2GB.
-    CMDLINE.C, VMS_IM.C, VMS_PK.C, ZIP.C, ZIP_CLI.CLD, ZIP_CLI.HELP,
-    ZIPUP.H (SMS)
-17. Update command line options to support -VV as distinct option (Ed)
-18. More VMS changes (SMS)
-19. Add zoff_t format function (SMS)
-20. On VMS, when -b was not used, temporary archive files were always
-    created in the current default directory, rather than in the archive
-    file destination directory.  VMS now uses its own tempname()
-    function.  FILEIO.C, VMS.C (SMS)
-21. Remove using FNMAX for path size in a few places including filetime.c
-    to avoid exceeding limit (based on fixes from Greg and others) (Ed)
-22. Add port atheos (Ruslan Nickolaev, Ed)
-23. Bug fix adds different extra fields for local and central in VMS (SMS)
-24. Now short options also take optional values as next argument (Ed)
-25. Change -dd to control -v dots (SMS, Ed)
-26. On VMS, a new open callback function senses (where supported) the
-    process RMS_DEFAULT values for file extend quantity (deq),
-    multi-block count (mbc), and multi-buffer count (mbf), and sets the
-    FAB/RAB parameters accordingly.  The default deq is now much larger
-    than before (16384, was none), and the default mbc is now 127
-    (up from 64), speeding creation of a large archive file.  Explicitly
-    set RMS_DEFAULT values override built-in defaults.  OSDEP.H, VMS.C
-    (SMS)
-27. VMS CLI definitions and CLI help have been updated, and may be
-    approximately correct.  CMDLINE.C, ZIP_CLI.CLD, ZIP_CLI.HELP (SMS)
-28. The man file zip.1 updated and Makefile updated to generate manual
-    pages for zipcloak.1, zipnote.1, and zipsplit.1 (Ed)
----------------------- July 23rd 2005 version 3.0e ----------------------
- 1. Debian patch 004 - apply 2.4i configure changes from Onno to remove
-    need for -fno-builtin in unix/configure (Onno, Ed)
- 2. Debian patch 005 for bug 279867 - fix bug that could crash on large paths
-    and create security problem.  Apply patch changes from Greg (Greg, Ed)
- 3. SourceForge patch 1074363 - add win32i64.c to win32/makefile.w32 (Ed)
- 4. Add check when not ZIP64_SUPPORT in scanzipf_reg() in zipfile.c if
-    Zip64 archive being read (Ed)
- 5. Renamed fzofft() used to format zoff_t values to zip_fzofft() to remove
-    conflict when combined with UnZip in WiZ (Mike)
- 6. Add check in scanzipf_reg() in zipfile.c if Zip64 archive being read (Ed)
- 7. Fixes for amiga/makefile.azt to define directory for object files (Paul)
- 8. Define prototypes for local functions optionerr, get_shortopt and
-    get_longopt in fileio.c.  Define err argument of optionerr as ZCONST (Paul)
- 9. Add help_extended and DisplayRunningStats prototypes, fix other prototypes
-    in zip.c (Paul)
-10. Split int kk off of k for argument types (Paul)
-11. Aztec #endif quirk fix in zip.c for Amiga (Paul)
-12. Add detection of binary in first buffer read from file in zipup.c to avoid
-    a -l or -ll translation on binary file.  Not perfect but at least should
-    catch some binary files (Ed)
-13. Remove check for >= 128 from binary check in zipup.c as <= 6 enough for
-    signed char (SMS, Ed)
-14. SF Bug 1074368 - check for empty zip file in readzipfile() in zipfile.c
-    (Christian d'Heureuse, Ed)
-15. Add error exit to prevent archive corruption when updating a large-file
-    archive with a small-file program.  Add ZE_ZIP64 error.
-    ziperr.h, zipfile.c (SMS)
-16. Change percent() in zipup.c to do rounding better, handle cases near limits
-    while rounding, and allow negative percent returns (SMS, Ed)
-17. Add function ffile_size() in zipfile.c but in #if 0 block until determine
-    if works on all ports under all conditions.  Currently only used for size
-    check for Zip64 archive detection if compiled without ZIP64_SUPPORT and
-    this check may already be handled in scanzipf_reg() and should be added to
-    scanzipf_fix() when that is updated (SMS, Ed)
-18. Change >>1 to /2 in zipsplit.c to allow for negative percent returns (SMS)
-19. Add type uzoff_t for unsigned zoff_t things.  Should clean up some casting
-    (Ed)
-20. Based on discussions with other development groups, when data descriptors
-    (extended local headers) are used, force to Zip64.  This is compatible
-    with other unzips and does not require a change of the AppNote, but the
-    resulting archive requires Zip64 to read.  Using standard data descriptors
-    would mean that the zip operation would fail if a Zip64 entry was
-    encountered.  See zipfile.c (Ed)
-21. Add define SPLIT_SUPPORT to enable splits.  The command line options are
-    done and the globals are set up but nothing more.  globals.c, zip.h, and
-    zip.c mainly (Ed)
-22. Create spanning signature at beginning of archive when splitting enabled.
-    If reading a split archive skip the spanning signature unless creating a
-    split archive.  zip.c, globals.c (Ed)
-23. Start implementing split archives.  Define two methods. split_method = 1
-    updates local headers and is the most compatible but requires updating
-    previous splits.  split_method = 2 uses data descriptors and should work
-    for streams and removable media but may not be as compatible with other
-    zip applications.  (In part based on previous discussions with Rainer.)
-    Updated global variables to include bytes written to just the current
-    entry in the current split.  zipfile.c (Ed)
-24. Add note about output redirection to zip.1 (?, Ed)
-25. Remove num < 0 check as num now unsigned.  util.c (SMS, Ed)
-26. Change lastchar to lastchr in fileio.c in places to avoid function by same
-    name (SMS, Ed)
-27. Moved #endif /* !WINDLL */ in zip.c (Mike)
-28. Account for vms directory version being ;1.  vmszip.c (SMS)
-29. Fix Zip64 check in scanzipf_reg to use the buffer.  zipfile.c (Ed)
-30. Default define size_t (for use by Steve's ffile_size() function).  tailor.h (Ed)
-31. Enable Steve's ffile_size() function and enable large file check.  It
-    currently does not allow file sizes over 2 GB but the code is not supporting
-    it anyway without large file support.  Should remove that part of the check
-    when the casts are fixed.  zipfile.c (Ed)
-32. Fixes for djgpp.  Now compiles with djgpp 2 (Ed)
-33. Add new VC6 projects for win32 and windll (Cosmin)
-34. Convert some variables in zipsplit.c from ulg to zoff_t so compiles (Ed)
-35. Add wildcards to extended help.  zip.c (Ed)
-36. For optional option value now '-' is same as missing value.  fileio.c (Ed)
-37. Remove extra free() from -dd option switch.  zip.c (Ed)
-38. Change write_unsigned_to_mem() to write_ulong_to_mem() and write_short_to_mem()
-    to write_ushort_to_mem().  zipfile.c (Ed)
-39. Create new append to mem functions.  zipfile.c (Ed)
-40. Change zlist nam and ext from extent to ushort as that is what gets written.
-    zipfile.c (Ed)
-41. Change GetSD to use ush instead of size_t.  win32/win32zip.c (Ed)
-42. Change PutLocal(), PutExtended(), PutCentral(), and PutEnd() to write to
-    memory and then write the block at once to the file.  zipfile.c (Ed)
-43. Change zcomlen from extent to ush, other extent conversions.  zipfile.c,
-    globals.c, zip.h (Ed)
-44. Add is_seekable() and global output_is_seekable.  Do seekable check
-    when output file is opened.  zipup.c, globals.c, zip.h, zip.c (Ed)
-45. Do not increment files_so_far and bytes_so_far if file could not be read.
-    zip.c (Ed)
-46. If force_zip64 set, only force compressed size in central directory to Zip64
-    instead of all entries (csize, usize, off, disk) in Zip64 extra field.  This
-    fixes inconsistent handling of disk numbers.  zipfile.c (Ed)
-47. Add end status if displaying running stats and not all files were read.
-    zip.c (Ed)
-48. Change force_zip64 to zip64_archive in putend().  zipfile.c (Ed)
-49. Enable the i686-optimized code by default.  crc_i386.S,
-    win32/crc_i386.asm, win32/crc_i386.c (Cosmin)
-50. Document and implement a new text detection scheme provided by Cosmin in
-    set_file_type().  Should be able to handle UTF-8 and some other character sets.
-    proginfo/txtvsbin.txt, trees.c (Cosmin, Johnny, Christian)
-51. Update binary detection for -l and -ll to use Cosmin black list.  zipup.c (Ed)
-52. Change ZE_BIG to include read and write.  ziperr.h (Ed)
-53. If archive not seekable then use data descriptors.  If ZIP64_SUPPORT always
-    create Zip64 data descriptors and add a Zip64 extra field to flag it is
-    a Zip64 data descriptor.  This is klugy but should be compatible with other
-    unzips.  See the note in zipfile.c for details.  (Ed)
-54. Use ush for comment length in putend().  Instead of extent use ush for
-    zcount and fcount same as in zip file.  zip.h (Ed)
-55. Update VB readme.  windll/VB/readmeVB.txt (Ed)
-56. Change (INSTALL) to (INSTALL_PROGRAM).  unix/Makefile (, Ed)
-57. During update the file and byte status counts were off.  Fixed by not coun-
-    ting files copied from old to new as those are not in totals.  zip.c (Ed)
-58. Change from -b to -bx for nroff of manuals to text files.  unix/Makefile (Ed)
-59. Add cygwin to makefile.  unix/Makefile (, Ed)
-60. Fix bug where files to delete not added to list.  zip.c (Ed)
-61. Fix delete stats.  zip.c (Ed)
-62. Increment version of crypt to 2.10.  Update default behavior notes.
-    crypt.c, crypt.h (Paul, Christian)
-63. Format changes, add parentheses to zfseeko(), fix output bytes, add ifdef
-    blocks for ZIP10, fzofft formatting, casts.  crypt.c (Christian)
-64. Cast block_start to unsigned.  deflate.c (Christian)
-65. Let -R patterns match in subdirectories.  Update filter() to use switch,
-    use global icount and Rcount, handle subdirectories, update icount and
-    RCount in filterlist_to_patterns().  fileio.c, zip.c, zip.h, globals.c
-    (Christian)
-66. Enclose option -! and use_privileges under NTSD_EAS guard.  globals.c,
-    zip.c, zip.h (Cosmin)
-67. Updates to version, copyright, license.  [I did not split the copyright
-    to 2 lines as it already takes up space on the help screen.  Ed]
-    revision.h (Christian)
-68. Add ZCONST to some read-only string pointer arguments in function
-    declarations.  zipcloak.c, zipnote.c, zipsplit.c, zip.c, zip.h (Christian)
-69. Fix byte counts on exit in zipcloak() and zipbare() to fix zipcloak bug
-    (Christian)
-70. Modified zipnote.c to use WRBUFSIZ to handle line widths of at least 2047
-    characters in write mode (Christian)
-71. Change simple() and greedy() from zoff_t to uzoff_t.  zipsplit.c (Christian)
-72. Remove duplicate copyright notices.  zipsplit.c (Christian)
-73. Remove export notice from help page.  Move notice to bottom of license
-    page.  zipcloak.c (Ed)
-74. File USexport.msg export history added. (Greg)
-75. Added support for VMS ODS5 extended file names.  (Eight-bit only, no

-     Found that using -dd with an optional value got confusing as detection
-     of an optional argument, when the next argument was not either an option
-     or the end of the line, was easy to overlook.  Easier to avoid optional
-     values.  zip.c (Ed)
-121. Change text output of manual pages to zip.txt, zip.txt, zipcloak.txt,

-150. Change Zip64 not supported warning in scanzipf_reg().  zipfile.c (Ed)
-151. Fix bug where local and central headers were not matching when compiled
-     with NO_LARGE_FILE_SUPPORT.  Restored order of zlist structure elements
-     to match order of local header as scanzipf_reg() compares it as an
-     array of bytes to the local header.  Gag.  It needs fixing but at least
-     it works as intended now.  zip.h, zipfile.c (Ed)
-152. Minor fix from 10000 to 10 K for WriteNumString().  util.c (Ed)

-     does.  fileio.c (Ed)
-167. If bytes_total is smaller than bytes_so_far for some reason then display
-     negative of bytes_to_go.  This can happen if files grow in size after all
-     the sizes are initially added up.  zip.c (Ed)
-168. Use usize from filetime for adding to bytes_total when updating instead
-     of size in old entry.  zip.c (Ed)
-169. Change status counts files_so_far and bytes_so_far to include bad files
-     so the status counts end at the end but add bad_files_so_far and
-     bad_bytes_so_far to track bad files.  After minor fixes it looks like
-     the counts remaining at the end are correct, even when some files are
-     not readable.  Update bad file warnings.  zip.c, zip.h, globals.c,
-     zipup.c (Ed)
-170. Add uq for unsigned q in zipup().  Initialize z->len in case an error
-     later so have a valid size.  zipup.c (Ed)
-171. Check noisy in DisplayRunningStats() so logging is independent of it.
-     zip.c (Ed)

-     user.  zip.c, msdos/msdos.c, msdos/osdep.h (Johnny)
-173. Add errno.h for strerror(errno) call.  zip.c, zipup.c (SMS)
-174. Fix log problem if using -q option.  zipup.c (Ed)
-175. Change "Far char" to "char Far" as Far is a qualifier not for the char
-     type but the storage allocation of the array.  fileio.c (Christian)
-176. Update note on extent.  globals.c (Christian, Ed)
-177. Remove extra USE_ZLIB.  zip.c (Christian)
-178. Add note for the OEM_RUSS '/' bug.  Need to look at later as it seems
-     the Russian bug remains unfixed.  zipfile.c (Christian, Ed)
-180. So byte counts always come out even, create good_bytes_so_far to
-     count bytes read in and convert bytes_so_far to use the counts
-     from the initial scan.  If files change during the zip operation
-     good_bytes_so_far will change and not match bytes_so_far.
-     zip.h, globals.c, zip.c (Ed)
-181. Changes to extended help.  zip.c (Ed)
-182. Update WhatsNew (Ed)
-183. Update DLL resource copyright.  windll.rc, windll.aps (Ed)
-184. Add directory search improvements to Win32 (within recursion, reuse
-     attribs from directory lookup to avoid calling stat()).  Add
-     getd_attribs(), procname_win32().  win32/win32zip.c (Johnny)
-185. Cache result of IsFileSystemOldFAT() to avoid repetitive system calls
-     for identical information.  win32/win32.c  (Johnny)
-186. Add optimization to dosmatch(): apply alternate shortcut code when the
-     pattern to match consists of one multichar wildcard ('*') followed
-     by a fixed string.  util.c (Johnny)
-187. Move DOS check_for_windows() checks to Help and Version and errors
-     only.  Shorten message to one line.  zip.c, msdos/msdos.c (Ed)
-188. Define WIN32_OEM to enable oem ansi conversions for more than RSXNT.
-     Not yet fully implemented.  win32/win32.c, win32zip.c, zip.c,
-     zipfile.c (Ed)
-189. Directory search improvements for MSDOS.  msdos/msdos.c (Johnny)
-190. Add caching of directory information.  If pattern is just *string no
-     need to recurse.  win32/win32.c (Johnny)
-191. If wild_stop_at_dir then do recurse to handle cases like a/b/*.txt.
-     win32/win32.c (Ed)
-192. Additional improvements to directory search speedups, including
-     a) MSDOS port fixes for Turbo C++ compiler
-     b) In both Win32 and MSDOS, change getDirEntryAttr() into macro,
-        saving one function call overhead
-     e) Add explaining comment to optimized procname_{local} code
-     f) In util.c, move "*literal" pattern-matching optimization from
-        dosmatch() to recmatch(). Advantages:
-        - optimization used for all systems
-        - optimization applied to all occurences where a "*" is last wildcard
-          in pattern
-        - "dosmatch()" only preconditoning wrapper for matching workhorse
-          "recmatch()", it should not implement matching algorithms itself
-        - optimization not applied for WILD_STOP_AT_DIR option
-     g) >>>disabled<<< "*literal" optimization for all MBCS-aware environments,
-        because suspect that supplied optimization code is not MBCS-clean
-        (for details see the comment within the patch), so IS NOT USED for
-        win32 port!  Can force activation of match optimization by specifying
-        conditional compilation symbol TEST_FOR_MBCS_CLEAN.
-     (Christian)
-193. Add and move comments, implement changes for directory search improvements
-     in Zip 3.0 util.c (Ed)

-     and on AIX 4.2.0. AIX 5.1 with gcc-3.4.3 (32-bit) and Darwin built fine
-     - though AIX 5.1 needed CC=gcc make -e ... to find gcc.  According to the
-     HP-UX man page -Ae is equivalent to -Aa -D_HPUX_SOURCE +e it seems the
-     +e is needed and -Ae is more terse anyway."  Expression generated before
-     was too long.  unix/configure (Rodney Brown)
-199. Add support for osf4.0f that does not have fseeko or ftello but has 64-bit

- 2. Add -zq and use assembler.  os2/makefile.os2 (Christian)
- 3. Update header.  os2/match32.asm (Christian)
- 4. Change len from int to unsigned int.  os2/os2.c (Christian)
- 5. In GetLongPathEA() limit tempbuf to CCHMAXPATH.  os2/os2.c (Christian)

- 8. Add UNICODE_SUPPORT define.  zip.h, zip.c (Ed)
- 9. Add oname to f and z structs for the display name to use in messages.
-    Change z->zname to z->oname in messages.  fileio.c, zip.c, win32zip.c,
-    zipup.c, zipfile.c, zip.h (Ed)
-10. Move multi-byte defines to make global (they were needed with wide
-    characters but that was taken out and left them where they are).
-    fileio.c, zip.h
-11. Add copy_args(), free_args(), and insert_arg() to create copy of argv
-    that can free() and to support inserting "@" in get_option for lists.
-    fileio.c, zip.h
-12. Insert arg "@" after list if not followed by option.  fileio.c
-13. Add args variable and copy argv to args so can use insert_arg(). zip.c
-14. Add MKS Korn Shell note.  zip.c
-15. Change cast of option in add_filter() calls from char to int. zip.c
-16. Implement multi-byte version of Unicode support.  To support Win32 NT
-    wide calls will require additional work not planned for this release.
-    Changes include (Ed):
-    - Add use_wide_to_mb_default flag.  globals.c, zip.h
-    - Add compiler UNICODE_SUPPORT version information.  zip.c
-    - Add uname to f and z structs for UTF-8 name. zip.c
-    - Moved some defines out of ZIP64 section.  zipfile.c
-    - Add define UTF8_PATH_EF_TAG for Unicode Path extra field.  Currently
-      the tag is 0x7075 which is 'u' 'p' for Unicode path and seems
-      free according to the AppNote.  The extra field is
-        tag (2 bytes 'u' 'p')
-        size (2 bytes)
-        Unicode Path size (2 bytes)
-        unused (2 bytes set to 0)
-        unused (2 bytes set to 0)
-        Unicode path (variable)
-      The unused locations also serve as a check in case the tag is in
-      use already.
-    - Add add_Unicode_Path_local_extra_field() and
-      add_Unicode_Path_cen_extra_field() functions. zipfile.c
-    - Add read_Unicode_Path_entry() function. zipfile.c
-    - Set uname and oname in scanzipf_ref(). zipfile.c
-    - Add define wide_to_mb_default.  Add zchar but not used. win32/osdep.h
-    - Add wide command line reading but don't use. win32/win32.c
-    - Add port functions for Unicode, including local_to_utf8_string(),
-      wide_to_escape_string() (for converting a wide character that can't be
-      converted to mb in the local character set to a reversable escape string),
-      escape_string_to_wide(), wide_to_local_string(), local_to_display_string()
-      (for creating the display version of name), utf8_to_local_string(),
-      local_to_wide_string(), wide_to_utf8_string() (NOT IMPLEMENTED), and
-      utf8_to_wide_string() (NOT IMPLEMENTED).  win32/win32.c
-    - Implement attempt at escape function.  Whenever a wide character can't
-      be mapped to the local character set, this function gets called.
-      Currently the wide character is converted to a string of hex digits.
-      If the wide can fit in 2 bytes then the form #1234 is used.  If not,
-      the 4-byte form #L12345678 is used.
-    It compiles but needs the utf8 functions implemented.  Also needs testing
-    in a multi-byte environment and only Windows is implemented so need to at
-    least do Unix. (Ed)
-17. Update freeup() to include uname and oname.  zip.c
-18. Move define wide_to_mb_default so default for all is '_'. zip.h (Ed)
-19. No changes needed to osdep.h and update unix/unix.c but not tested. (Ed)
----------------------- October 19th 2005 version 3.0f02 ----------------------
- 1. Remove null value check for split_size as get_option() already checks.
-    zip.c (Ed)
- 2. Update f$search().  vms/descrip.mms (SMS)
- 3. Save parse name before search and use that on failure.  Change name parsing
-    in ziptyp() to solve a problem with search-list logical name device directory
-    specs.  vms/vms.c (SMS)
- 4. Compile in UNICODE_SUPPORT if have wchar_t and mbstowcs().  unix/configure (Ed)
- 5. Move Unicode defines to zip.h and functions to fileio.c so generic.  Create
-    a new OEM function for Windows.  fileio.c, zip.h, tailor.h, win32/win32.c (Ed)
- 6. Add UTF-8 functions.  fileio.c (Paul)
- 7. Convert Unicode functions to use zwchar defined as unsigned long for wide
-    char.  fileio.c, zip.h (Ed)
- 8. Add wchar_t check for Unix.  unix/configure (Ed)
- 9. Add default when zwchar (4 bytes) is too big for wchar_t (2 bytes).  zip.h (Ed)
-10. Allow for states for wide characters but surrogates not done.  fileio.c (Ed)
-11. Update WhatsNew (Ed)
----------------------- December 16th 2005 version 3.0f03 ----------------------
- 1. Fix broke encryption when ZIP64_SUPPORT enabled by accounting for need for
-    data description when encrypting.  Data description is not required for
-    encryption (WinZip does not use one) but seems needed by Zip for some reason.
-    zipfile.c (Ed)
- 2. Add function bfwrite() to do buffered fwrite().  Most output already is
-    written by zfwrite used by crypt.c which now calls bfwrite.  All splitting
-    and new byte counts are done in bfwrite.  fileio.c (Ed)
- 3. Move some functions out of ZIP64_SUPPORT defines for use with UNICODE_SUPPORT.
-    zipfile.c, zip.h (Ed)
- 4. Add is_ascii_string() and only create Unicode extra field if z->iname is
-    not ascii.  zipfile.c, zip.h, fileio.c,  (Ed)
- 5. Add parameter rewrite to putlocal() to note when rewriting bytes so the bytes
-    rewritten are not counted in output totals.  zipfile.c, zip.h (Ed)
- 6. Handle VMS ... wildcard.  util.c (SMS)
- 7. Make tempzip file name global.  zip.c, globals.c, zip.h (Ed)
- 8. Add out_path global and -O path option to allow the output archive to have a
-    different name than the input archive, if there is one.  This allows
-    updating a split archive, since output to the same split name would otherwise
-    be complicated and not user friendly.  Use out_path for output.  zip.h,
-    zip.c, globals.c (Ed)
- 9. Many output functions that had output file y as parameter, such as zipup(),
-    zipcopy(), putlocal(), putcentral(), and putend(), now do not as y is
-    now global.  This allows changing y as splits are created.  zip.c (Ed)
-10. Add function zipmessage() for writing messages like zipwarn() but are
-    informational.  zip.c (Ed)
-11. Minor changes to help.  zip.c (Ed)
-12. Add SPLIT_SUPPORT to version output.  zip.c (Ed)

-14. Add set_filetype() to set attributes of split.  zip.c (Ed)
-15. Change variable a (holds attributes) to zipfile_attributes and make global.
-    zip.c, zip.h, globals.c (Ed)
-16. Add key_needed flag for encryption and move setting key to after
-    command line processed.  zip.c (SMS)
-17. Initialize dot size using default only if dot_size not set.  zip.c (Ed)
-18. Change command line processing so that last -P or -e is used.  zip.c
-    (Ed)
-19. Fix broke writing of 4-byte spanning signature at the beginning of the archive
-    if splitting.  zip.c (Ed)
-20. Use bfcopy() instead of fcopy() to copy archive beginning.  bfcopy() uses
-    global y.  zip.c (Ed)
-21. It looks like tempzf is no longer used.  zip.c (Ed)
-22. Account for SUNPRO_C and DECC_VER.  Change SPARC to Sparc.  unix/unix.c (SMS)
-23. Remove GNUC.  vms/cmdline.c (SMS)
-24. Change case of system calls.  vms/vms.c (SMS)
-25. Add fix for VMS ... matching, but may change Zip to avoid ex2in() and in2ex()
-    for pattern matching in future.  vms/vmszip.c (SMS)
-26. Remove /NODIRNAMES and /DIRNAMES from VMS help.  vms/zip_cli.help (SMS)
-27. Define new globals zip64_eocd_disk, zip64_eocd_offset, current_local_tempname,
-    bytes_this_split, and bytes_this_entry for splits.  globals.c, zip.h (Ed)
-28. Add SUNPRO C and DEC C compile checks.  unix/configure (SMS)
-29. Add CFLAGS_NOOPT for removing optimization for configure.  unix/Makefile (SMS)
-30. Modify crypthead() to use bfwrite().  crypt.h, crypt.c (Ed)
-31. Modify zfwrite() to use global output file.  crypt.h, crypt.c (Ed)
-32. Modify zfwrite() when no encryption to use bfwrite().  crypt.h (Ed)
-33. Add bfcopy() to copy to y.  fileio.c (Ed)
-34. Add close_split() and bfwrite() for splits.  fileio.c (Ed)
-35. Add is_ascii_string() to check if UTF-8 extra field is needed.  fileio.c (Ed)
-36. Change Unicode escape of 2-byte wide from #1234 to #U1234.  fileio.c (Ed)
-37. Add read_Unicode_Path_entry() to read the UTF-8 path extra field.  zipfile.c (Ed)
-38. Latest Unicode Path extra field format is
-      1 byte     Version of Unicode Path Extra Field
-      2 bytes    Name Field Checksum
-      variable   UTF-8 Version of Name
-39. Use CRC-32 for Unicode Path Checksum and AND halves.  zipfile.c (Paul)
-40. Add Unicode Path Checksum check to make sure extra field applies to Name field
-    still.  zipfile.c (Christian)
-41. Move get_extra_field() out of Zip64 block and make available for splits.
-    zipfile.c (Ed)
-42. Check in putlocal() using is_ascii_string() and don't create Unicode path
-    extra field if name is ASCII characters.  zipfile.c (Ed)
-43. If local header for split is on another disk and using split method 1, close
-    that split in putlocal() after rewrite local header.  zipfile.c (Ed)
-44. Fix data descriptor bug when encrypting where putextended() did not handle the
-    not Zip64 case, which mostly only happens now for encryption.  zipfile.c (Ed)
-45. Check for ASCII name using is_ascii_string() in putcentral() for Unicode path
-    extra field.  zipfile.c (Ed)
-46. Instead of single disk values, update putend() to use real split values for
-    current_disk, cd-start_disk, cd_entries_this_disk, cd_start_offset,
-    zip64_eocd_disk, zip64_eocd_offset, and current_disk and allow for
-    needing Zip64 if exceed standard max values for current_disk, cd_start_disk,
-    cd_entries_this_disk, total_cd_entries, and cd_start_offset.  zipfile.c (Ed)
-47. Use current_local_offset and current_local_disk for z->off and z->dsk in
-    zipup().  zipup.c (Ed)
-48. Fix bug where force_zip64 was used to determine descriptor size but can have
-    Zip64 entry without force_zip64 so use zip64_entry.  zipup.c (Ed)
-49. Change the p - o != s compression size test for splits to bytes_this_entry
-    != (key ? s + 12 : s) and avoid ftell() in split.  zipup.c (Ed)
-50. If local header is on a previous split and split method 1 do the seek on that
-    split to update header.  zipup.c (Ed)
-51. For streaming, only force Zip64 if reading stdin and writing a non-seekable
-    device.  In other cases can detect either the input file size and set Zip64
-    if needed or seek in the output to update the local headers.  zipup.c,
-    zipfile.c, zipup.c (Ed)
-52. Allow creation of stored archives with descriptors for testing.  Currently
-    they can't reliably be read but this is planned.  zipup.c, zipfile.c, zip.c
-    (Ed)
-53. Update help, adding in -e, -P, -s splitsize, -sp, and -sv options.  zip.c (Ed)
-54. Spelling fix in zipsplit man page.  man/zipsplit.1, zipsplit.txt (Ed)
-55. New option -sv and variable noisy_splits to enable verbose splitting.
-    Default is to quietly create splits, unless -sp set to pause between splits.

- 5. Initialize many variables such as y and tempzip.  zip.c, fileio.c,
-    zipfile.c (Ed)
- 6. Add loop to pause during split method 2 to allow changing disk or changing
-    the path for the next split.  fileio.c (Ed)
- 7. If after starting new split there is not enough room for the remaining buffer
-    for split method 1 display error and exit and for split method 2 we can
-    display a warning and user can replace disk or change path.  fileio.c (Ed)
- 8. Add list to store input file arguments using add_name() to add the name to
-    filelist_struc filelist and then process the names after the input archive
-    is read.  zip.c (Ed)
- 9. Fix infinite loop when opening a log file whose name contains multiple '/'.
-    zip.c (Cosmin)

-    zip.h, zip.c, zipup.c, fileio.c (Ed)
- 5. Make dot_count and dot_size uzoff_t, dot_count because with global dots
-    dot_count does not reset and with terabyte files the number of buffers

- 5. Change is_ascii_string to use 0x7F for ASCII detection.  fileio.c (Ed)
- 6. Add copy_only global for when -O is used to change the format of an
-    archive without changing the contents.  This allows for converting an
-    archive to a split archive for instance.  The global copy_only is used
-    to output status information for copies when normally copied files
-    have no status messages.  globals.c (Ed)
- 7. Add in_file, split_path, total_disks, current_in_disk, and
-    current_in_offset as globals to track reading splits.  zip.h,

-    copying instead of error message *Nothing to do*.  zip.c (Ed)
-14. If zipbeg is just 4 bytes and spanning then assume is spanning
-    signature and set zipbeg to 0 to ignore.  zip.c (Ed)
-15. Don't open initial write test as modify if have_out is set and so have
-    a separate output file.  zip.c (Ed)
-16. If zipbeg is 0 and nothing at beginning of archive to copy then don't
-    open input file until zipcopy() does.  zip.c (Ed)
-17. If stuff at beginning then copy and close input file.  Should be able
-    to keep it open but easier to close it and let zipcopy() reopen it.
-    zip.c (Ed)
-18. Add status message when copy_only set so something is displayed.
-    zip.c (Ed)
-19. Instead of closing x at bottom close in_file.  The variable x was used
-    inconsistently and it seemed easier to make in_file global instead.
-    Then again y remains the global output variable.  zip.c (Ed)
-20. Update copyright.  zipnote.c, zipsplit.c, zipcloak.c (Ed)
-21. Change adjust_zip_local_entry() to return 1 if the entry is Zip64 and
-    0 if not.  This is needed to know how large the extended local header
-    is later.  zipfile.c (Ed)
-22. Add read_Unicode_Path_local_entry() to read the local version of the
-    Unicode Path extra field.  zipfile.c (Ed)
-23. Handle disk in adjust_zip_central_entry().  zipfile.c (Ed)
-24. Change USE_NEW_READ to SPLIT_SUPPORT as splits seems to be stable more
-    or less.  zipfile.c (Ed)
-25. Add is_signature() to compate signatures.  zipfile.c (Ed)
-26. Create scanzipf_fixnew().  It should look like scanzipf_regnew().
-    zipfile.c (Ed)
-27. Change scanzipf_regnew() to read the central directory and create zlist
-    and handle reading traditionally.  Allows using central directory
-    information, in particular file sizes, in zipcopy() while reading
-    entries.  Use global in_file instead of f for input file and set to NULL
-    when not a valid file so finish() only tries to close it if needed.
-    Check to make sure the End Of Central Directory record found is infact
-    the last one in case a stored archive is in the last 64 KB.  Refuse
-    to update a split archive but recommend using -O instead.  zipfile.c (Ed)
-28. Change readable check in readzipfile() to require input archive to exist
-    if using -O out_archive.  zipfile.c (Ed)
-29. Change putlocal() to not create a Zip64 extra field unless needed and
-    on rewriting the local header to remove Zip64 extra field if was created
-    but not needed.  Add check if assumed entry does not need Zip64 but does,
-    meaning probably the uncompressed size is less than 4 GB but the
-    compressed size is over 4 GB.  zipfile.c (Ed)
-30. Change zipcopy() to use the global in_file and y files and to open and
-    close read splits as needed.  Checks the local header against the
-    central directory header to verify same file, which should be as using
-    the disk and offset values from the central directory.  Update disk and
-    offset in central directory.  zipfile.c (Ed)
-31. Change out_path and out_len to base_path and base_len in
-    get_split_path().  fileio.c (SMS)
-32. Update command line options for VMS to include verbose splitting.
-    vms/zip_cli.cmd, vms/cmdline.c (SMS)
-33. Handle HP.  unix/unix.c (SMS)
-34. Add adler16() checksum function.  util.c (Cosmin)
-35. Use FILE_FLAG_BACKUP_SEMANTICS and a less demanding access mode
-    in CreateFile() when retrieving file attributes.  Fixes a problem
-    when adding a directory entry from an NTFS or a CDFS partition
-    (i.e. one that stores timestamps using universal time), and the
-    directory timestamp is not the same daylight savings time setting.
-    The effect is an offset in the timestamp by one hour, if zip is
-    built using NT_TZBUG_WORKAROUND. The problem is not exposed,
-    however, if NO_W32TIMES_IZFIX is defined.  win32/win32.c (Cosmin)
----------------------- March 19th 2006 version 3.0f09 ----------------------
- 1. Fix encryption problem where a large file with uncompressable data

- 3. Add zip_fzofft() for outputting uzoff_t bin size c.  zipsplit.c (SMS)
- 4. Add only_archive_set and clear_archive_bits to do Window archive bit
-    selection and clearing.  Add -AS option to require DOS Archive bit
-    be set and -AC to clear archive bits of included files.  Add
-    ClearArchiveBit() to clear archive bits after archive created.
-    Only Win32.  globals.c, zip.h, zip.c, win32zip.c, win32.c (Ed)
- 5. Change procname_win32() and readd() to check archive bit.

-    warning.  zip.c (Ed)
-11. Copy Zip 2.32 csharp example, though it is designed for zip32.dll and
-    not zip32z64.dll from Zip 3.0.  Updated note.  windll/csharp (Ed)
-12. Change -M to -MM and define -mm to avoid accidental use of -m.
-    zip.c (Ed)
-13. Define split_method -1 to not allow splitting, mainly used when reading
-    a split archive to stop automatic splitting of output with same
-    split size.  Now -s=0 or -s- disables splitting.  zip.h, globals.c,
-    zip.c (Ed)
-14. Add fflush() after dots displayed.  deflate.c, fileio.c, zipup.c (Ed)
-15. Instead of assuming buffer size as 32 KB for dots, use WSIZE for
-    compressing and SBSZ for storing and calculate as dots are counted.
-    Now dot_count and dot_size are bytes instead of buffers.  Add dots
-    to Delete and Archive modes.  zip.c, zipup.c, deflate.c, fileio.c (Ed)
-16. If reading a split archive and split size has not been given, get
-    size of first split read by zipcopy(), which should be the first
-    split, and set split size to that, making the output archive the same
-    split size as the input archive.  Delay -sv split size message
-    if split size is 0 at first but then changed.  zipfile.c (Ed)

-18. Fix cd_start_offset bug.  fileio.c (Ed)
-19. Create new action ARCHIVE that looks for matches only in old archive
-    for Copy Mode.  If no input paths and there is an output archive,
-    Copy Mode is assumed even without ARCHIVE.  Old default Copy Mode
-    when no input files updated to work like -U mode and allow filters.
-    New global copy_only currently only used to control global dots.
-    zip.c, fileio.c, globals.c, zip.h (Ed)

-    examples from top basic section.  Indent examples.  Help for new
-    --out and Copy Mode.  Add warnings that output using data descriptors
-    may not be compatible with some unzips.  Update dots help and add
-    warning that dot size is approximate.  Add help for new DOS archive
-    bit options.  More help for -b and -MM.  zip.c (Ed)
-21. Add support for Unix FIFO (named pipe).  Add set_extra_field() stat
-    name ending in '/' fix found in Zip 2.32.  unix/unix.c (Ed)
-22. Add check to not allow setting -U (internal copy) in similar cases to
-    -d (delete).  zip.c (Ed)
-23. Add counts for internal modes Delete and Archive.  Byte counts for -db
-    remain uncompressed size for external modes, but internal modes Delete
-    and Archive now use compressed sizes as these copy that many bytes.
-    zip.c (Ed)
-24. Add check for when ftell() wraps. zipup.c (Ed)
-25. Add mesg_line_started = 0 to result percentage message.  zipup.c (Ed)

-    and not on stdout as list can be long.  Only list totals on stdout.
-    zip.c (Ed)
-17. Create check_unzip_version().  Fix Unix check.  Zip still creates
-    the temporary archive then does the check, and if it fails
-    the archive is deleted, even if the check fails because of the wrong
-    verion of UnZip.  On Unix only 'unzip' the system version of UnZip
-    is checked, not './unzip' which would allow putting a local more
-    up to date version of UnZip in the current directory for the check.

-11. Add note for bzip2.  zip.c (Ed)
-12. Do not do seek wrap test if ftell() returns -1 as from a pipe.  Add
-    output of last ftell() and current ftell() for zipfile too big seek
-    error.  zipup.c (Ed)

-    central directory say they are.  This allows all recovered entries to
-    be complete with all central directory information.  Calculate CRC of
-    input entry and compare to CRC from central directory.  Allow skipping
-    split disks the user may not have.  Store state of output archive

-    '?' in the name.  These are characters in the Unicode name stored on
-    disk but not represented in the multi-byte character set used by zip
-    for the scan.  In this case, return the short name in 8.3 format so
-    directory scan can continue.  Could put the Unicode name in the Unicode
-    extra field, but not done.  Add warning when long name is replaced
-    by short name.  Not fully tested.  win32/win32zip.c, zip.h, zip.c,
-    fileio.c (Ed)

- 3. Instead of tempname use temp_name as parameter to avoid function
-    tempname().  zipsplit.c, zipnote.c, zipcloak.c, zip.c (Ed)
- 4. If fixing archive with -FF and no EOCDR to get disk count, see if top of
-    archive has spanning signature or local header and guess if it is

-    are not installed.  zip.c (Ed)
- 8. If new global unicode_escape_all is set, then escape all non-ASCII
-    characters when converting Unicode file path.  This allows viewing paths
-    as escapes on Unix that would otherwise be white space.  If not set, any
-    characters that map to the current locale are returned as is.  Can only
-    display if either supported as base by the OS or fonts installed.  Set
-    using -UN=escape option.  zip.c, fileio.c, zip.h, globals.c (Ed)

- 1. Add note for UnZip.  crypt.c (Christian)
- 2. Change current_disk and disk_number from int to ulg.  Change num from int
-    to unsigned int.  [Even though a 16-bit system likely won't see more than

-    match from long to int as the number of possible options should always fit
-    in that.  fileio.c, globals.c (Christian)
- 3. Use -Gt to force some data into separate data segments so all data fits.
-    msdos/makefile.msc (Christian)

-    the next signature and that reads a byte at a time, the scan buf is only
-    used to read in the found headers.  Since we skip the extra parts of the
-    Zip64 EOCDR, all headers are a fixed size.  Remove unused variables from
-    scanzipf_fixnew().  Use ENDCOM for end comment offset.  Instead of 64 KB
-    seek back 128 KB to find EOCDR.  Use ENDOFF and ENDTOT for offsets in

-    allows -FF to work on .exe sfx files without adding .zip.  zipfile.c (Ed)
- 7. Fix bug where only backed up 20 bytes to find Z64 EOCD Locator.  Now back
-    up 24 bytes to include size of Z64 EOCD Locator signature.  This prevented

-    zip.c (Ed)
- 6. In GetFileMode() and GetFileModeW() when get attributes fails
-    instead of fprintf(mesg, ...) use zipwarn() so error goes in
-    log file and new lines are displayed when needed.  win32/win32.c (Ed)
- 7. In GetSD(), change cbytes from long to ulg.  Check cbytes (the
-    compressed size of the security descriptor) and issue warning if
-    the compressed security descriptor is greater than 0x7FFF (32k)
-    as the entire header this extra field is in needs to fit in the
-    64k header.  Should be a check on the running size of the header

-    function would be used to allow Unicode escapes on the command line
-    without using the -UN=escape option, but the utility of this is still
-    being determined.  zipfile.c (SMS, Ed)
- 3. Remove declaration for unused bz_deflate_init().  zipup.c (SMS, Ed)

- 1. Update copyright.  Add check for NO_UNICODE_SUPPORT.  tailor.h (Ed)
- 2. Fix bug where Unicode General Purpose Bit Flag 11 should force keeping
-    the old name field but it was being overwritten by the escaped name
-    in the central directory header.  Fixed some ZIPERR() calls in
-    putcentral() that referred to putlocal().  zipfile.c (Ed)
- 3. Add comment about OCRCU8 and OCRCTB.  unix/configure (Ed)
- 4. Change line in instructions to note that manuals should be made after
-    Zip is made.  Change OCRTB to OCRCTB.  Add $(OCRCTB) to rule for

------------------------- May 12th 2008 version 3.0h10 ----------------------
- 1. Add use of new Unix UID/GID extra field and of old Unix 16-bit UID/GID
-    extra field when system uses 16-bit UIDs/GIDs to version information.
-    zip.c (SMS, Ed)

------------------------- May 19th 2008 version 3.0h11 ----------------------
- 1. Initialize f->namew when streaming stdin to fix bug.  fileio.c (Ed)
- 2. Change force_zip64 to start as -1 as unset, then use 1 for forcing use
-    of Zip64 and 0 for disabling use of Zip64.  Add negation of -fz to
-    prevent use of Zip64 during streaming from stdin to a non-seekable
-    output where data descriptors will be used, which allows creating
-    archives with the old stream format but will fail if a large file is
-    streamed.  Default is still to force Zip64 data descriptors when
-    streaming, which covers all cases but requires a Zip64 compatible
-    unzip.  zip.c, globals.c, zipfile.c (Ed)
- 3. Handle case of bad Unicode in archive.  zipfile.c (Ed)
------------------------- May 22nd 2008 version 3.0h12 ----------------------

- 2. Change non existent to nonexistent.  unix/configure (SMS)
- 3. Don't output blank line when zipmessage_nl() gets passed an empty
-    string.  This removes blank lines for skipped entries when -FS used.
-    zip.c (Ed)
------------------------- May 27th 2008 version 3.0h13 ----------------------
- 1. Change UNICODE_ALLOW_FORCE to UNICODE_SUPPORT, -UN=force to -UN=UTF8,
-    and unicode_force to utf8_force.  This option now standard with Unicode
-    support and forces Zip to save UTF-8 paths and comments, when not ASCII,
-    as if UTF-8 were the native character set.  globals.c, zip.c, zip.h (Ed)
- 2. Add note to Todo that it's out of date.  TODO (Ed)

------------------------- May 31st 2008 version 3.0h ------------------------
- 1. In putlocal() if using UTF-8 bit then also set UTF-8 bit in z->lflg so
-    is set in local header for streaming.  zipfile.c (Ed)
- 2. Update announcement date for beta.  zip30h.ann (Ed)
- 3. Rename lib and dll projects to zip32z64 and update project files so
-    project name is same as lib and dll libraries.  Export make files.
-    windll/visualc/dll/zip32z64.dsp, windll/visualc/dll/zip32z64.dsw,

-Zip 3.0 is the first Zip update adding large file support.  For now Zip 2.3x
-remains available and supported, but users should switch to this new release.
-
-Testing for Zip 3.0 has focused mainly on Unix, VMS, Max OS X, and Win32,
-and some other ports may not be fully supported yet.  If you find your
-favorite port is broke, send us the details or, better, send bug fixes.  It's
-possible that support for some older ports may be dropped in the future.

-Copyright (c) 1990-2008 Info-ZIP.  All rights reserved.
-
-See the accompanying file LICENSE (the contents of which are also included
-in unzip.h, zip.h and wiz.h) for terms of use.  If, for some reason, all
-of these files are missing, the Info-ZIP license also may be found at:
-ftp://ftp.info-zip.org/pub/infozip/license.html and
-http://www.info-zip.org/pub/infozip/license.html.
-
-
-Zip 3.0 is a compression and file packaging utility.  It is compatible with
-PKZIP 2.04g (Phil Katz ZIP) for MSDOS systems.  There is a companion to zip
-called unzip (of course) which you should be able to find in the same place
-you got zip.  See the file 'WHERE' for details on ftp sites and mail
-servers.
-
-So far zip has been ported to a wide array of Unix and other mainframes,
-minis, and micros including VMS, OS/2, Minix, MSDOS, Windows, Atari, Amiga,
-BeOS and VM/CMS.  Although highly compatible with PKware's PKZIP and PKUNZIP
-utilities of MSDOS fame, our primary objective has been one of portability
-and other-than-MSDOS functionality.  Features not found in the PKWare version
-include creation of zip files in a pipe or on a device; VMS, BeOS and OS/2
-extended file attributes; conversion from Unix to MSDOS text file format; and,
-of course, the ability to run on most of your favorite operating systems.  And
-it's free.
-
-See the file zip30.ann for a summary of new features in Zip 3.0 and WhatsNew
-for the detailed list of new features and changes since Zip 2.32.  The file
-CHANGES details all day-to-day changes during development.
-
-Notes:
-
-Multi-volume support.  This version does not support multi-volume spanned
-archives as in pkzip 2.04g, and there is no intention at this point to support
-spanned archives, but Zip 3.0 supports split archives.  A split archive is an
-archive split into a set of files, each file a piece of the archive and each
-file using an extension, such as .z02 as in the file name archive.z02, that
-provides the order of the splits.  In contrast, a spanned archive is the
-original multi-floppy archive supported by pkzip 2.0g where the split order
-is contained in the volume labels.  The contents of split and spanned archives
-are mostly identical and there is a simple procedure to convert between the
-formats.  Many current unzips now support split archives.
-
-Zip64 support.  This version supports Zip64 archives as described in the
-PKWare AppNote.  These archives use additional fields to support archives
-greater than 2 GB and files in archives over the 2 GB previous limit (4 GB
-on some ports).  The Zip64 format also allows more than 64k entries in an
-archive.  Support by the OS for files larger than 4 GB is needed for Zip to
-create and read large files and archives.  On Unix, Win32, and some other
-ports, large file and Zip64 support is automatically checked for and
-compiled in if available.  Use of Zip64 by Zip is automatic and to maximize
-backward compatibility the Zip64 fields will only be used if needed.  A
-Zip64 archive requires a pkzip 4.5 compatible unzip, such as UnZip 6.0.
-
-Unicode support.  This version has initial Unicode support.  This allows
-paths and names of files in other character sets to be accurately recreated
-on OS that have sufficient character set support.  On Win32, if wide
-character calls are supported (not Win 9x unless Unicode support has been
-added) all files (including paths with illegal characters in the current
-character set) should now be readable by zip.  Unicode support is provided
-using a new set of UTF-8 path and comment extra fields and a new UTF-8 bit
-for flagging when the current character set is already UTF-8.  Zip 3.0
-maintains backward compatibility with older archives and is mostly compliant
-with the new Unicode additions in the latest PKWare AppNote.  The exception
-is UTF-8 comments, which are not supported if UTF-8 is not the native
-character set, but should be fully implemented in Zip 3.1.
-
-16-bit OS support.  Though Zip 3.0 is designed to support the latest zip
-standards and modern OS, some effort has been made to maintain support
-for older and smaller systems.  If you find Zip 3.0 does not fit on or
-otherwise does not work well on a particular OS, send in the details and
-we might be able to help.
-
-Compression methods.  In addition to the standard store and deflate methods,
-Zip now can use the bzip2 compression format using the bzip2 library.  Though
-bzip2 compression generally takes longer, in many cases using bzip2 results
-in much better compression.  However, many unzips may not yet support
-bzip2 compressed entries in archives, so test your unzip first before using
-bzip2 compression.
-
-Installation.  Please read the file INSTALL for information on how to compile
-and install zip, zipsplit, zipcloak, and zipnote and please read the manual
-pages ZIP.txt, ZIPSPLIT.txt, ZIPCLOAK.txt, and ZIPNOTE.txt for information on
-how to use them.  Also, if you are using MSDOS or Windows, note that text
-files in the distribution are generally in Unix line end format (LF only)
-and Windows and DOS users will need to either convert the files as needed to
-DOS line ends (CR LF) or extract the distribution contents using unzip -a.
-
-Utilities.  At this point zipsplit, zipcloak, and zipnote should work with
-large files, but they currently do not handle split archives.  A work around
-is to use zip to convert a split archive to a single file archive and then use
-the utilities on that archive.
-
-Encryption.  This version supports standard zip encryption.  Until recently
-the encryption code was distributed separately because of the US export
-regulations but now is part of the main distribution.  See crypt.c for
-details.  Decryption can be made with unzip 5.0p1 or later, or with zipcloak.
-
-Bug reports.  All bug reports or patches should go to zip-bugs via the web
-site contact form at http://www.info-zip.org/zip-bug.html (we have discontinued
-the old email address zip-bugs@lists.wku.edu because of too much spam lately)
-and suggestions for new features can be submitted there also (although we don't
-promise to use all of them).  We also are on SourceForge at
-http://sourceforge.net/projects/infozip/ and now automatically get Bug Reports
-and Feature Requests submitted there.  In addition, a new Info-ZIP discussion
-forum is available as well.  See below.  Though bug reports can be posted there,
-we don't have automatic monitoring of all postings set up yet so you may want
-to use the web form or SoureForge for a quicker response.  A good approach may
-be to post the details on the forum so others can benefit from the posting,
-then use the web reply form to let us know you did that if you don't get a
-reply in a reasonable time.
-
-Ports.  If you're considering a port, please check in with zip-bugs FIRST,
-since the code is constantly being updated behind the scenes.  We'll
-arrange to give you access to the latest source.
-
-Discussion group.  If you'd like to keep up to date with our Zip (and companion
-UnZip utility) development, join the ranks of BETA testers, add your own
-thoughts and contributions, etc., check out the new discussion forum.  This is
-the latest offering, after the various Info-ZIP mailing-lists on
-mxserver@lists.wku.edu (courtesy of Hunter Goatley) were no longer available
-and the temporary QuickTopic discussion group for Info-ZIP issues at
-http://www.quicktopic.com/27/H/V6ZQZ54uKNL died a horrible death due to large
-amounts of spam.  The new discussion forum is now available at
-http://www.info-zip.org/board/board.pl (thanks again to Hunter Goatley) and
-can be used to discuss issues, request features, and is one place new betas
-and releases are announced.  It also is a place to post bug reports, and
-patches can be submitted as attachments.  However, we don't yet get
-automatic notification of all postings there so try one of the other methods
-if you don't get a response.  You can also post Bug Reports and Feature
-Requests at Source Forge.  However, the web site contact form remains
-available if you would rather not post on the public forums.
-
-Frequently asked questions on zip and unzip:
-
-Q. When unzipping I get an error message about "compression method 8".
-
-A. This is standard deflate, which has been around for awhile.  Please
-   get a current version of unzip.  See the file 'WHERE' for details.
-
-
-Q. How about "compression method 12"?
-
-A. Compression method 12 is bzip2 and requires a relatively modern unzip.
-   Please get the latest version of unzip.
-
-
-Q. I can't extract this zip file that I just downloaded.  I get
-   "zipfile is part of multi-disk archive" or some other message.
-
-A. Please make sure that you made the transfer in binary mode.  Check
-   in particular that your copy has exactly the same size as the original.
-   Note that the above message also may actually mean you have only part
-   of a multi-part archive.  Also note that UnZip 5.x does not and UnZip 6.0
-   probably won't have multi-disk (split) archive support.  A work around
-   is to use Zip 3.0 to convert the split archive to a single-file archive
-   then use UnZip on that archive.  As a last result, if there's something
-   readable in what you have, zip -FF should be able to recover it.
-
-
-Q. When running unzip, I get a message about "End-of-central-directory
-   signature not found".
-
-A. This usually means that your zip archive is damaged, or that you
-   have an uncompressed file with the same name in the same directory.
-   In the first case, it makes more sense to contact the person you
-   obtained the zip file from rather than the Info-ZIP software
-   developers, and to make sure that your copy is strictly identical to
-   the original.  In the second case, use "unzip zipfile.zip" instead
-   of "unzip zipfile", to let unzip know which file is the zip archive
-   you want to extract.
-
-
-Q. Why doesn't zip do <something> just like PKZIP does?
-
-A. Zip is not a PKZIP clone and is not intended to be one.  In some
-   cases we feel PKZIP does not do the right thing (e.g., not
-   including pathnames by default); in some cases the operating system
-   itself is responsible (e.g., under Unix it is the shell which
-   expands wildcards, not zip).  Info-ZIP's and PKWARE's zipfiles
-   are interchangeable, not the programs.
-
-   For example, if you are used to the following PKZIP command:
-               pkzip -rP foo *.c
-   you must use instead on Unix:
-               zip -R foo "*.c"
-   (the quotes are needed to let the shell know that it should
-    not expand the *.c argument but instead pass it on to the program,
-    but are not needed on ports that do not expand file paths like
-    MSDOS)
-
-
-Q. Can I distribute zip and unzip sources and/or executables?
-
-A. You may redistribute the latest official distributions without any
-   modification, without even asking us for permission. You can charge
-   for the cost of the media (CDROM, diskettes, etc...) and a small copying
-   fee.  If you want to distribute modified versions please contact us at
-   www.Info-ZIP.org first. You must not distribute beta versions.
-   The latest official distributions are always on ftp.Info-ZIP.org in
-   directory /pub/infozip and subdirectories and at SourceForge.
-
-
-Q. Can I use the executables of zip and unzip to distribute my software?
-
-A. Yes, so long as it is made clear in the product documentation that
-   zip or unzip are not being sold, that the source code is freely
-   available, and that there are no extra or hidden charges resulting
-   from its use by or inclusion with the commercial product.  See the
-   Info-ZIP license for more.  Here is an example of a suitable notice:
-
-     NOTE:  <Product> is packaged on this CD using Info-ZIP's compression
-     utility.  The installation program uses UnZip to read zip files from
-     the CD.  Info-ZIP's software (Zip, UnZip and related utilities) is
-     freely distributed under the Info-ZIP license and can be obtained as
-     source code or executables from various anonymous-ftp sites,
-     including ftp://ftp.info-zip.org/pub/infozip.
-
-
-Q. Can I use the source code of zip and unzip in my commercial application?
-
-A. Yes, as long as the conditions in the Info-ZIP license are met.  We
-   recommend you include in your product documentation an acknowledgment
-   and note that the original compression sources are available at
-   www.Info-ZIP.org. If you have special requirements contact us.

-  This is Info-ZIP's README.CR for zcrypt29.zip, last updated 27 March 2008.
-_____________________________________________________________________________
-
-
-The files described below contain the encryption/decryption code for Zip 2.31,
-UnZip 5.52, and WiZ 5.02 (and later).  These files are included in the main
-source distributions for all of these now, but the encryption patch is still
-available for earlier versions of these.  This file both describes the history
-of the encryption package and notes the current conditions for use.  Check
-the comments at the top of crypt.c and crypt.h for additional information.
-
-As of version 2.9, this encryption source code is copyrighted by Info-ZIP;
-see the enclosed LICENSE file for details.  Older versions remain in the pub-
-lic domain.  Zcrypt was originally written in Europe and, as of April 2000,
-can be freely distributed from the US as well as other countries.
-
-(The ability to export from the US is new and is due to a change in the Bureau
-of Export Administration's regulations, as published in Volume 65, Number
-10, of the Federal Register [14 January 2000].  Info-ZIP filed the required
-notification via e-mail on 9 April 2000; see the USexport.msg file in this
-archive.  However, as of June 2002, it can now be freely distributed in both
-source and object forms from any country, including the USA under License
-Exception TSU of the U.S. Export Administration Regulations (section 740.13(e))

-    FOR ANY DAMAGES RESULTING FROM THE USE OF THIS SOFTWARE.
-
-The encryption code is a direct transcription of the algorithm from
-Roger Schlafly, described by Phil Katz in the file appnote.txt.  This
-file is distributed with the PKZIP program (even in the version without
-encryption capabilities).  Note that the encryption will probably resist
-attacks by amateurs if the password is well chosen and long enough (at 
-least 8 characters) but it will probably not resist attacks by experts.
-Paul Kocher has made available information concerning a known-plaintext
-attack for the PKWARE encryption scheme; see http://www.cryptography.com/
-for details.)  Short passwords consisting of lowercase letters only can be
-recovered in a few hours on any workstation.  But for casual cryptography
-designed to keep your mother from reading your mail, it's OK.
-
-For more serious encryption, check into PGP (Pretty Good Privacy), a
-public-key-based encryption system available from various Internet sites.
-PGP has Zip and UnZip built into it.  The most recent version at the time
-this was originally written was 6.5, although older versions were still
-widespread.  At the time of this writing there are now GPG, PGP Universal
-2.0, and various others based on OpenPGP.
-
-We are looking at adding AES strong encryption to future versions of Zip and
-UnZip.
-
-Zip 2.3x and UnZip 5.5x and later are compatible with PKZIP 2.04g.  (Thanks
-to Phil Katz for accepting our suggested minor changes to the zipfile format.)
-
-IMPORTANT NOTE:
-
-  Zip archives produced by Zip 2.0 or later must not be *updated* by
-  Zip 1.1 or PKZIP 1.10 or PKZIP 1.93a, if they contain encrypted members
-  or if they have been produced in a pipe or on a non-seekable device.
-  The old versions of Zip or PKZIP would destroy the zip structure.  The
-  old versions can list the contents of the zipfile but cannot extract
-  it anyway (because of the new compression algorithm).  If you do not
-  use encryption and compress regular disk files, you need not worry about
-  this problem.
-
-
-Contents that were distributed and now are part of the main source files:
-
-  file           what it is
-  ----           ----------
-  README.CR      this file
-  LICENSE        Info-ZIP license (terms of reuse and redistribution)
-  USexport.msg   export notice sent to US Bureau of Export Administration
-  WHERE          where Zip/UnZip/WiZ and related utilities can be found
-  crypt.c        code for encryption and decryption
-  crypt.h        code for encryption and decryption
-  file_id.diz    description file for some BBSes
-
-Most all of the files are in Unix (LF only) format.  On MSDOS systems, you
-can use the -a option of UnZip to convert the source files to CRLF
-format.  This is only necessary if you wish to edit the files -- they
-will compile as is with Microsoft C and Turbo/Borland C++ 1.0 or
-later.  However, you will have to convert the files (using "unzip -a")
-to the CRLF format to compile with the older Turbo C 1.0 or 2.0.  You
-should be able to find Zip and UnZip in the same place you found this 
-(see ftp://ftp.info-zip.org/pub/infozip/Info-ZIP.html or the file
-"WHERE" for details).
-
-Current releases all have encryption built in.  To update previous versions
-using the zcrypt sources:
-
-  (1) Get the main sources (e.g., Zip 2.3) and unpack into a working
-      directory, as usual.
-
-  (2) Overwrite the dummy crypt.c and crypt.h from the main sources with 
-      the versions from this package.  If you want to overwrite directly
-      out of the zcrypt29 archive, do not use UnZip's freshen/updating
-      option; the dummy files may be newer than the real sources in
-      zcrypt29.  ("unzip -o zcrypt29 -d /your/working/dir" will do the
-      Right Thing in most cases, although it may overwrite a newer WHERE
-      file under some circumstances.)
-
-  (3) Read the main INSTALL document and compile normally!  No makefile
-      changes are necessary on account of the zcrypt sources.  You can
-      check that the version you just compiled has encryption or decryption
-      support enabled by typing "zip -v" or "unzip -v" and verifying that
-      the last "special compilation option" says encryption or decryption
-      is included.
-
-Encryption enables new "-e" and "-P password" options in Zip, and a new
-"-P password" option in UnZip--see the normal Zip and UnZip documentation
-for details.  (Note that passing a plaintext password on the command line
-is potentially much more insecure than being prompted for it interactively,
-which is the default for UnZip and for Zip with "-e".  Also note that the
-interactive method allows UnZip to deal with archives that use different
-passwords for different files.)

-Todo list (last updated 12 June 2008).
-
-Features for next official version:
-
-- Extended attributes for Windows, Linux, and Mac OS X.
-- Win32 ACL rewrite to use backup api to create new and more useful extra
-  field (need unzip support) (Kai).
-- Allow -d@ to read in a list of names to delete (11/17/2005).
-- AES encryption (3/19/05).
-
-Features that may make the next release:
-
-- Allow reading in list of files using @filename.
-- When -R, -x, or -i pattern ends in a directory add / to the end
-      (11/5/2004 Nehal).
-- Decide if -R, -i and -x should use external rather than internal patterns.
-      Also, change pattern matching to not do ex2in() and then in2ex() if
-      appropriate.  (12/26/2005 SMS)
-- Though Unicode paths have been implemented and tested, Unicode comments
-      are not yet supported (except for comments on UTF-8 native systems which
-      are supported).
-- Verbose mode -v may still need work.
-
-- Add C# example for Zip 3.0 (need to be converted to new DLLs) - original
-      C# example added with note.
-- Path Prefix maybe, so entries added to an archive can have a directory
-      path string prepended to each path so can zip multiple drives and avoid
-      name conflicts (4/17/2006).
-- UNC paths like \\server\path (4/26/2005).
-- Support for other languages maybe.
-
-- Add About page option similar to -h2 and -v but lists Info-ZIP
-      information (could be -sa) (4/29/2006).
-- Update utilities ZipSplit, ZipNote, and ZipCloak to handle split archives.
-- Update ziperr and finish if needed.
-- Review memory allocation and fill in memory leaks if any.
-- Enhance -FF to fix common problems such as archives ftp in text mode
-      and fixing checksums so entries can be extracted if that makes
-      sense (6/17/2007).
-- Add \ to / conversion in zipsplit to fix problem in
-      1/29/2004 email.
-- Encryption bug with small stored file (12/27/2005) (fixed?).
-
-- When updating large archives with few entries being
-      updated maybe display something in large periods of
-      quiet (1/23/2006).
-- Windows OEM comments (5/17/2006).
-- Example of using MVS zip and unzip (3/30/2004) (Need one).
-- UTF-8 comments need to be implemented (6/17/2007)
-- Maybe convert ../ in archive (5/20/2006).
-- Per so many buffers dll callback (12/23/2005 Ale).
-- Allow rename stdin "-" to something else (12/27/2005 gregor).
-- Check for possible buffer overrun weaknesses while reading zip files.
-- Do Active Template Library (ATL) (4/27/2005).
-- Flush Win16 support - to be determined (Mike).
-- Way to convert file names on input, converting foo.c to dir/foo_bar.c
-      for instance (4/8/2004, 3/12/2004).
-- French WiZ (not a Zip thing actually but dependent on zip and unzip).
-- Then there is that wierd ^D being converted to \000 error reported
-      in 6/21/2003 email when Zip is outputted into a pipe on Windows ports.
-
-Old list:
-
-Main features still missing for next official version (last updated 2/11/2001):
-
-- what about the binary/text detection ? (seems done)
-- -b and -t options in help screen (covered in -h2)
-- findfirst/findnext and after that LSSTAT (performance!!)
-- use IS_EXEC from djgpp stat.h
-- use install in unix/Makefile instead of mkdir -p, look at install sh script.
-- #elif for those ports that can handle it.
-- what about zopen vs. fopen ?
-- Add zcreate or zfcreate for win32.
-- Assembler stuff in match.S (subexpressions)
-- zipping huge files (> 2G, unsigned 32bit) (done)
-- Testsuite for zip and unzip (John D. Mitchell)
-- make a version.c or version.h that includes all the compiler names
-- run utils with dmalloc().
-- what to do with zip -F and zip -FF (readzipfile2()) ? (done?)
-- profiling of the code
-- multi disk zip files (could be done)
-- zipfile modification tool (Greg)
-- Implement -- option (Thomas Klauser, wiz@danbala.tuwien.ac.at) (could be done)
-- don't add files with "Archive bit" or add files with "Archive bit"
-	(uwe.becher@metronet.de) (could be done with -AS and -AC)
-- 32 bit file attributes
-- generate output without having to seek at all (this seems to be stream output)
-- remove contractions from zip error messages, make them clearer (Steve)
-- display "[text]" for ascii files when not quiet (no -q) (Timo Salmi)
-- does zipnote accept names with version number?
-- for a WORM, zip should create temp file only when updating; new archives
-	should be created directly.
-- APPNOTE.TXT specifies "4) The entries in the central directory may
-      not necessarily be in the same order that files appear in the zipfile"
-      but readzipfile() relies on same order. (new read does not, and now
-      the read for -FF searches for central directory matches rather than
-      rely on the order)
-- on Mac, MPW C 3.3.1 requires #if (a || b)  ["#if a || b" taken as "#if a"]
-- on Unix, let -S be "include non-regular files without reading from them"
-	(as pkzip on Unix). This requires unzip support.
-- zip -l should do ebcdic->ascii translation on CMS and MVS
-- zip as subroutine (zdig/241) (some work done on this)
-- accept k and M in zipsplit
-- store / (part of file name) as ! in OS/2 (problem only with -E ?)
-- in addition to -l (LF to CR LF) and -ll (CR LF to LF) add -lc
-	(LF to CR LF but CR LF remains unchanged)
-
-Known bugs:
-
-- On VMS, zip fails reading some files with "byte record too large for
-	user's buffer". You must use the "-V" option for such files.
-	(many changes to VMS so may be fixed)
-
-- on MSDOS, zip386.exe does not like "zip -bc: foo ..."
-
-- on MSDOS, zip386.exe is sometimes much slower than zip.exe. This is
-	probably a problem with DJGPP (to be investigated).
-
-- on NT with C shell, zip should not do file name expansion again.
-
-- zip zipfile ... ignores existing zipfile if name does not have an extension
-      (except for the -A option, generally used on self-extracting files).
-      (archives should probably have extensions.  Things like archive.jar work)
-
-- For an sfx file without extension, "zip -A sfx" works but "zip sfx -A"
-	doesn't.  (because options were required first, but now both OK)
-
-- When storing files in a zipfile (-0), zip marks all of them as binary.
-
-- On VMS, some indexed files are not restored correctly after zip -V and unzip.
-	(This is now known to be a problem of UnZip. The workaround for Zip 2.2
-	and newer is to use PK-style VMS extra fields; this is now the default.
-	NOTE that UnZip 5.32 has been fixed [971019]!) (many VMS changes so
-	this may be fixed)
-
-- zip and unzip should use the same pattern matching rules, particularly
-	on MSDOS and OS/2. On OS/2, "zip foo *.*" should also match files
-	without extension.
-	Partially DONE (OS/2 "*.*" matches "*".)
-
-- there should be a way to avoid updating archive members (only addition
-	of new files allowed)

-(1) This notice is being sent in order to ensure that we may legally

-    "corresponding object code."  The encryption code in question is
-    unchanged since our original notification of 9 April 2000, appended

-    (Indeed, there has been no change to the core encryption/decryption
-    code in well over five years.)
-
-(2) The (larger) source archives for Zip, UnZip, MacZip, WiZ, and

-    directory given above, also contain (or may contain) copies of
-    the same zcrypt source code.
-
-(3) ftp.info-zip.org currently points to a site in Germany, so techni-
-    cally it is not involved in "US export" in any direct way.  However,
-    we encourage other sites to "mirror" our software, and some of these
-    mirror sites may be US-based (and therefore involved in reexport of
-    the code in question).  In addition, some Info-ZIP members reside in
-    the US, and www.info-zip.org currently points to a site in Kentucky.

-What's New
-
-Last updated 1 July 2008
-
-This file is the full list of new features and major changes for Zip 3.0
-by beta release.  See the announcement file zip30.ann for a quick summary
-of all features and changes in Zip 3.0.  Also see the file README for
-release information, INSTALL for installation procedures, and the manual
-pages zip.txt, zipsplit.txt, zipcloak.txt, and zipnote.txt for how to use
-the new features.  The file CHANGES has all the day-to-day changes made
-during development.
-
-
-Below are some of the more significant items on the list for Zip 3.1
-(see ToDo for a more complete list):
-
-- AES encryption.
-- Extended attributes for Windows, Linux, and Mac OS X.
-- Support -d@ for deleting list of files.
-- Decide if -R, -i and -x should use external rather than internal patterns.
-- Though Unicode paths have been implemented and tested, Unicode comments
-  are not yet supported (except for comments on UTF-8 native systems which

-
-
-MAJOR CHANGES BY BETA VERSION
------------------------------
-
-New things in Zip 3.0 since Zip 3.0h:
-
-- Unicode fixes.
-- Test and fix various ports as needed.
-- Update Win32 resource to support more Windows ports.
-- Add djgpp 2.x makefile that includes bzip2.
-- Add Win32 version resource to Win32 executable.
-- Bug fixes.
-- Documentation updates.
-- Package for release.
-
-
-New things in Zip 3.0h
-
-- Allow -@ and -x to work together.
-- Unicode code cleanup.
-- Allow forcing use of UTF-8 storage in standard path and comment.
-- Update symbolic link checks.
-- Add support for storing 32-bit UIDs/GIDs using new extra field.
-  Backward compatible support for the old 16-bit UID/GID extra field
-  remains if Zip is compiled on an OS that has 16-bit UID/GID
-  storage.
-- Update VMS notes.
-- Directory scan using -AS (include only files with Windows archive
-  bit set) now ignores archive bit on directories to include all files
-  with archive bit set in all directories.  Also, to avoid empty
-  directories being created, -AS now does not store directory
-  entries.
-- Add Unix IBM support.
-- Change -W to -ws to free -W for later use.
-- Fix large file support for MinGW.
-- Fix large file support for bzip2.
-- Fix compile error in ZipCloak when UNICODE_SUPPORT is not enabled.
-- Fix Unicode bug in ZipCloak involving Unicode paths.
-- Long Unicode escapes changed from #Lxxxxxxxx to #Lxxxxxx to shorten
-  paths with escaped Unicode.
-- Bug fixes.
-
-
-New things in Zip 3.0g
-
-- Add split support to VB project for Zip64.
-- Disable reading of Unix FIFOs unless new -FI option used to avoid an
-  archiving operation stopping when it hits an active unfed FIFO.
-- The "[list]" wildcard expression (regular expression matching of any
-  character or range of characters in list) is now disabled on DOS and
-  Windows as it has caused confusion when filenames have [ and ] in
-  them.  The new -RE option reenables it.
-- Add negation to many display options such as -dc and -db.
-- Allow -FF to read and fix archives having local entries that appear
-  after central directory entries.
-- Bug fixes.
-
-
-New things in Zip 3.0f
-
-- bzip2 - The bzip2 compression method looks supported for at least
-  Windows, Unix, and VMS using the bzip2 library.  A new option, -Z cm,
-  selects the compression method.
-
-- Split archives - Can now use -s to create a split archive.  The
-  default is to update split files as the archive is being written,
-  which requires all splits to remain open until the archive is done.
-  This should be no problem when writing the archive to a hard drive,
-  for example, and this approach creates archives that should be
-  supported by all unzips that support splits.  Adding the -sp option
-  enables split pause mode that instead writes splits that do not
-  need updating and pauses Zip after each split.  This allows splits
-  to be written directly to removable media, however -sp archives
-  may not be as universally compatible.
-
-- Unicode support - Zip now stores Unicode paths that should be more
-  portable across character sets and languages.  The unzip must have
-  Unicode support enabled or the Unicode paths are ignored.  If
-  reading an archive with Unicode paths, unsupported characters are
-  replaced by #Uxxxx and #Lxxxxxxxx escapes in the file name.  Option
-  -UN controls how Unicode is handled.  Also, on systems where the
-  current character set is UTF-8, preliminary support for the new
-  General Purpose Bit Flag, bit 11, UTF-8 flag, that indicates UTF-8
-  is stored in the path and comment fields is implemented for paths.
-- Unicode on Win32 - On WIN32 systems that support the wide character
-  calls (mainly NT and later systems using NTFS), when UNICODE SUPPORT
-  is enabled Zip will now do directory scans using Unicode and convert
-  the Unicode paths to the local character set for storage in the standard
-  path field and store UTF-8 in the Unicode extra field.  This allows
-  directory scans to complete successfully regardless of the character
-  set the path is in.  On Win9x systems wide character scans are not
-  generally supported and Zip automatically uses a local character scan
-  instead.
-
-- Keep extra fields option - The default operation has been, and continues
-  to be, to read then strip old extra fields when reading entries from an
-  existing archive and then recreate the extra fields that Zip knows about.
-  Extra fields specific to each operating system get added by default also.
-  The new option -X- (negated -X) keeps any old extra fields, copying
-  them to the updated archive unchanged (unless Zip has updated them).
-  The unnegated -X still strips most all extra fields except Zip64,
-  Unicode, and UT time.
-
-- License - minor updates to the license.
-
-- Windows OEM - When compiled with WIN32_OEM (the default for WIN32),
-  Zip on WIN32 now stores OEM paths, which should be more compatible
-  with other zips and should fix some character set problems.
-- Windows Archive Bit support - On Windows can now use new -AS
-  (include if archive bit set) option to select files with the DOS
-  archive bit set and use new -AC (clear archive bits) option to clear
-  the archive bits on files after the archive has been created.
-  But -DF is probably better.
-
-- Difference mode - A new option -DF (--dif) creates an output archive
-  that includes only files changed or new since the input archive was
-  created.  Can use to create incremental backups.
-- File Sync - The new option -FS enables File Sync, a new mode that
-  synchronizes the entries in an archive with the files on the file
-  system, adding updating, and deleting entries as needed.  This
-  should create the same results as creating a new archive, but
-  since existing entries are copied, may be much faster.
-
-- Copy Mode - A new --out option allows creating a new archive with a
-  different name than the input archive, leaving the input archive
-  unchanged.  This allows updating split archives.  It also allows
-  for a new copy mode to select entries in one archive and copy them
-  directly to a new archive.
-- Empty archives - Now an empty archive is created when -i or -i@ is used
-  and the file patterns given do not match anything.  This has been
-  requested to support scripts.
-
-- Global dots - A new -dg option now displays progress dots as -dd does,
-  but instead of displaying them for each file, the dots track the total
-  bytes read for the archive.  The -dg option also works when -q is used
-  to disable most output, which allows for something like zip -qdgds 100m
-  to be used to not display specific files but display a dot every 100 MB
-  as a global status.
-- Date range - Can now use -t and -tt to set a date range
-- Fix options - Option -F redone and can recover files from an archive
-  with a mostly complete central directory more reliably, but no longer
-  can handle truncated archives.  Option -FF redone and now can salvage
-  files from slightly more damaged archives, including truncated archives.
-  In some ways -F is less powerful but more stable than it was and -FF will
-  be needed where -F in Zip 2.32 was enough.  One big change is -F and -FF
-  both now support split archives.
-- Console writing - Updates to how messages are written to the console have
-  been made including more consistent handling of line breaks.
-- Show Files options - Option -sf lists the files that would be operated
-  on.  This option can be used alone to list the files in an archive.
-  Also see options -su and -sU for showing Unicode paths.
-- UnZip Check - Now check that UnZip 6.00 or later is being used for
-  unzip if testing a Zip64 archive.  A new option -TT can be used to set
-  the unzip to use with the -T check.  Currently UnZip does not support
-  split archives so split archives can't be tested by UnZip.
-- Streaming - Directories are now handled better when streaming.
-- Case matching - Normally all matching against archive entries is case
-  sensitive, so *.BAR will not match or find foo.bar in an archive
-  when deleting, copying, or freshening entries (deleting and copying
-  only on VMS).  New option -ic (--ignore-case) enables case insensitive
-  matching.  Currently -ic is only implemented on WIN32 and VMS.
-
-- Delete date bug fixed - Bug when using -d to delete files while
-  using -t or -tt to select the files based on date is fixed
-- Large file encryption bug fixed - Fix for bug that very rarely
-  results in bad data being stored when deflating and encrypting
-  uncompressable data and resulting in CRC errors when extracting,
-  but the chance of error increases with file size (thanks to
-  WinZip for finding this bug).  See CHANGES for details.
-
-
-New things in Zip 3.0e
-
-- Bugs described in Debian patches 004 (unix configure script update) and
-  005 (large path bug) fixed
-- Various fixes
-- Add optional running stats and also end stats if not all files could
-  be read
-- Options -l and -ll now do quick binary check on first buffer and skip
-  formatting if first buffer has binary - still check at end to note
-  if formatting was done on file that was later determined to be binary,
-  but now potential file corruption is generally avoided
-- Main binary check now uses new algorithm that should also treat UTF-8 and
-  other similar encodings as text, allowing proper line end translation
-  for UTF-8 files
-- When output is not updatable by seeking back and Zip64 is enabled, output
-  is forced to Zip64 to avoid possible later need for Zip64 when not enabled
-- More work on splits, but still not usable
-- Fixes for djgpp
-- Add log file capability to save all errors and optionally messages
-- Add code to test for a Zip64 archive when compiled without Zip64 support
-- New VC6 projects for Win32 and WinDLL
-- Updates to extended help
-- Changes to force-zip64 option
-- ZE_BIG error now given also for files too big to read or write
-- Fix file delete bug
-- Update license
-- Update export documentation
-- Add VMS extended filename support
-- Add directory traversal improvements, some for Win32 ports and some for
-  all ports, that can result in a 10 times increase in speed in some cases
-
-
-New things in Zip 3.0d
-
-- Some large file crypt fixes
-- Some updates to support WiZ
-- On VMS, changed -V (/VMS) processing to truncate file at EOF, allowing
-  greater compatability with non-VMS systems.  New -VV (/VMS=ALL) option
-  saves all allocated blocks in a file.  (Previously, -V did neither.)
-- On VMS, pushed 2GB file size limit with -V out to 4GB
-- On VMS (recent, non-VAX), with SET PROCESS /PARSE = EXTEND,
-  command-line case is preserved.  This obviates quoting upper-case
-  options, like -V, when enabled
-- On VMS, fixed problems with mixed-case directory names.  Also changed
-  to keep ODS5 extended file name escape characters ("^") out of the
-  archived names in simple cases
-- Changes to the display dots
-- Option -W should now force wildcard matching to not cross directory
-  separators.  For example, a/b*r/d will match a/bar/d but not a/ba/r/d
-- Option -nw should turn off all wildcard matching so foo[bar] is matched
-  literally and [bar] is not considered a regular expression
-- Atheos port
-- Debugging of Unix and VMS large file ports.  Most features may work now
-  on these ports for large files.  Still need to fix 2 GB to 4 GB when not
-  compiled with large file support
-- On VMS, added an open callback function which (where supported) senses
-  the process RMS_DEFAULT values for file extend quantity (deq)
-  multi-block count (mbc), and multi-buffer count (mbf), and sets the
-  FAB/RAB parameters accordingly.  The default deq is now much larger
-  than before (16384 blocks, was none), and the default mbc is now 127
-  (up from 64), speeding creation of a large archive file.  The "-v"
-  option shows some of the activity.  On old VMS versions, RMS_DEFAULT
-  sensing (GETJPI) fails (silently, without "-v"), and no changes will
-  be made.  Even there, (DCL) SET RMS /EXTEND = <big> can help
-  performance.  RMS_DEFAULT values override built-in default values.
-
-
-New things in Zip 3.0c
-
-- Converted to using 64-bit file environment instead of transitional functions
-  like fseeko64 for ports that support it
-- Added "--" argument to read all following arguments as paths
-- Second help page added
-- Binary detection adjusted from 20% binary is binary to 2%
-- When -R and -i used together now -i has precedence over -R
-- Archive names with spaces can now be tested on MSDOS and Win32
-
-
-New things in Zip 3.0b
-
-- Fixed ifdefs so can test base code by compiling with NO_LARGE_FILE_SUPPORT, then
-  compiling with NO_ZIP64_SUPPORT to test 64-bit file calls (if port enables) but
-  otherwise use base code, and compiling normally to enable Zip64 code
-- Unix Zip64 fixes - should now be able to create and read large files
-- WinDLL changes to support Zip64.  Zip 3.0 dll named Zip32z64.dll
-- New VB example to show use of Zip32z64.dll
-- New options -sc (show final command line and exit) and -sd (show each
-  step zip is doing, a little different than verbose which is still there) added
-  to help debug but both or at least -sd might go away in the release
-- Some minor posted bugs fixed (see Changes)
-
-
-New things in Zip 3.0a
-
-- Initial Zip64 support allowing large files and large numbers of files
-- New command line processor
-- Other changes, see file Changes
-
-
-Note:  Zip 2.4 was never released.  That code was the start of the Zip 3.0
-effort above.
-
-
-New things in Zip 2.3
-
-- IBM OS/390 port (Unix like, but EBCDIC) by Paul von Behren
-- Apple Macintosh (MACOS) port by Dirk Haase
-- Theos port by Jean-Michel Dubois
-- Multibyte characterset support by Yoshioka Tsuneo
-- Support for ISO 8601 date format with -t and -tt options
-- Info-ZIP license
-
-
-New things in Zip 2.2
-
-- BEOS port by Chris Herborth
-- QDOS port by Jonathan Hudson
-- TANDEM port by Dave Smith
-- WINDLL port (16-bit Win 3.x and 32-bit WinNT/Win95) by Mike White
-- SYSV packages support by John Bush
-- zip -P SeCrEt encrypts entries in the zip file with password SeCrEt
-  (WARNING: THIS IS INSECURE, use at your own risk)
-- zip -R recurses into subdirectories of current dir like "PKZIP -rP"
-- zip -x@exclude.lst excludes files specified in the file exclude.lst
-- zip -i@include.lst includes files specified in the file include.lst
-- zip -@ only handles one filename per line, but supports whitespace in names
-- zip -t mmddyyyy, 4 digit year number for uniqueness of years beyond 2000
-- zip -tt mmddyyyy only includes files before a specified date

-    See UnZip's INSTALL file for details.
-
-[**] As of January 2000, US export regulations were amended to allow export
-     of free encryption source code from the US.  As of June 2002, these
-     regulations were further relaxed to allow export of encryption binaries
-     associated with free encryption source code.  The Zip 2.31, UnZip 5.52
-     and Wiz 5.02 archives now include full crypto source code.  As of the
-     Zip 2.31 release, all official binaries include encryption support; the
-     former "zcr" archives ceased to exist.
-     (Note that restrictions may still exist in other countries, of course.)

- * 17 Jun 00, Paul Kienitz, added the PD-based tzset(), localtime(), and so on
- *            to amiga/filedate.c, replacing GNU-based functions which had
- *            replaced time_lib.c, both having been rejected for licensing
- *            reasons.  Support for timezone files and leap seconds was removed.
- *
- * 23 Aug 00, Paul Kienitz, split into separate timezone.c file, made platform
- *            independent, copied in mktime() and mkgmtime() from Zip, renamed
- *            locale_TZ as GetPlatformLocalTimezone(), for use as a generic
- *            hook by other platforms.

+
+    TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+    1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+    2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+    3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+    4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+    5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+    6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+    7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+    8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+    9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+    END OF TERMS AND CONDITIONS
+
+    APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.
+
+    Copyright [yyyy] [name of copyright owner]

+---- LLVM Exceptions to the Apache 2.0 License ----
+
+As an exception, if, as a result of your compiling your source code, portions
+of this Software are embedded into an Object form of such source code, you
+may redistribute such embedded portions in such Object form without complying
+with the conditions of Sections 4(a), 4(b) and 4(d) of the License.
+
+In addition, if you combine or link compiled forms of this Software with
+software that is licensed under the GPLv2 ("Combined Software") and if a
+court of competent jurisdiction determines that the patent provision (Section
+3), the indemnity provision (Section 9) or other Section of the License
+conflicts with the conditions of the GPLv2, you may retroactively and
+prospectively choose to deem waived or otherwise exclude such Section(s) of
+the License, but only in their entirety and only with respect to the Combined
+Software.

+Software from third parties included in the LLVM Project:
+==============================================================================
+The LLVM Project contains third party software which is under different license
+terms. All such code will be identified clearly using at least one of two
+mechanisms:
+1) It will be in a separate directory tree with its own `LICENSE.txt` or
+   `LICENSE` file at the top containing the specific license and restrictions
+   which apply to that software, or
+2) It will contain specific license and restriction terms at the top of every
+   file.
+

+_NodePtr algorithms
+
+The algorithms taking _NodePtr are red black tree algorithms.  Those
+algorithms taking a parameter named __root should assume that __root
+points to a proper red black tree (unless otherwise specified).
+
+Each algorithm herein assumes that __root->__parent_ points to a non-null
+structure which has a member __left_ which points back to __root.  No other
+member is read or written to at __root->__parent_.
+
+__root->__parent_ will be referred to below (in comments only) as end_node.
+end_node->__left_ is an externably accessible lvalue for __root, and can be
+changed by node insertion and removal (without explicit reference to end_node).
+
+All nodes (with the exception of end_node), even the node referred to as
+__root, have a non-null __parent_ field.

+// primes which the potential prime is not divisible by, the set of potential
+// primes more closely approximates the set of prime numbers.  And thus there
+// are fewer potential primes to search, and fewer potential primes to divide

+// ------------------------------------------------------------------------- //
+// This implementation of type_info assumes a unique copy of the RTTI for a
+// given type inside a program. This is a valid assumption when abiding to
+// Itanium ABI (http://itanium-cxx-abi.github.io/cxx-abi/abi.html#vtable-components).
+// Under this assumption, we can always compare the addresses of the type names
+// to implement equality-comparison of type_infos instead of having to perform
+// a deep string comparison.
+// -------------------------------------------------------------------------- //
+//                             NonUnique
+// -------------------------------------------------------------------------- //
+// This implementation of type_info does not assume there is always a unique
+// copy of the RTTI for a given type inside a program. For various reasons
+// the linker may have failed to merge every copy of a types RTTI
+// (For example: -Bsymbolic or llvm.org/PR37398). Under this assumption, two
+// type_infos are equal if their addresses are equal or if a deep string
+// comparison is equal.
+// -------------------------------------------------------------------------- //
+//                          NonUniqueARMRTTIBit
+// -------------------------------------------------------------------------- //
+// This implementation of type_info does not assume always a unique copy of
+// the RTTI for a given type inside a program. It packs the pointer to the
+// type name into a uintptr_t and reserves the high bit of that pointer (which
+// is assumed to be free for use under the ABI in use) to represent whether
+// that specific copy of the RTTI can be assumed unique inside the program.
+// To implement equality-comparison of type_infos, we check whether BOTH
+// type_infos are guaranteed unique, and if so, we simply compare the addresses
+// of their type names instead of doing a deep string comparison, which is
+// faster. If at least one of the type_infos can't guarantee uniqueness, we
+// have no choice but to fall back to a deep string comparison.
+//
+// This implementation is specific to ARM64 on Apple platforms.
+//
+// Note that the compiler is the one setting (or unsetting) the high bit of
+// the pointer when it constructs the type_info, depending on whether it can
+// guarantee uniqueness for that specific type_info.

 LOCAL MODIFICATIONS
 
+  Lua now uses a bestline REPL with bash-style code completion.
+
+  Integer literals such as `033` will now be interpreted as octal.
+
+  Integer literals such as `0b10` will now be interpreted as binary.
+
   The `\e` string literal escape sequence has been added, which is
   equivalent to `\27` (the Lua version of `\033`) or the ASCII ESC
   character. It may be used for teletypewriter control like having
   bold text, which can be encoded elegantly as `\e[1mHELLO\e[0m`.
+
+  Added luaL_traceback2() for function parameters in traceback.
+
+  Added Python-like printf modulus operator for strings.

-1 Notes on the Free Translation Project
-***************************************
-
-Free software is going international!  The Free Translation Project is
-a way to get maintainers of free software, translators, and users all
-together, so that free software will gradually become able to speak many
-languages.  A few packages already provide translations for their
-messages.
-
-   If you found this `ABOUT-NLS' file inside a distribution, you may
-assume that the distributed package does use GNU `gettext' internally,
-itself available at your nearest GNU archive site.  But you do _not_
-need to install GNU `gettext' prior to configuring, installing or using
-this package with messages translated.
-
-   Installers will find here some useful hints.  These notes also
-explain how users should proceed for getting the programs to use the
-available translations.  They tell how people wanting to contribute and
-work on translations can contact the appropriate team.
-
-1.1 INSTALL Matters
-===================
-
-Some packages are "localizable" when properly installed; the programs
-they contain can be made to speak your own native language.  Most such
-packages use GNU `gettext'.  Other packages have their own ways to
-internationalization, predating GNU `gettext'.
-
-   By default, this package will be installed to allow translation of
-messages.  It will automatically detect whether the system already
-provides the GNU `gettext' functions.  Installers may use special
-options at configuration time for changing the default behaviour.  The
-command:
-
-     ./configure --disable-nls
-
-will _totally_ disable translation of messages.
-
-   When you already have GNU `gettext' installed on your system and run
-configure without an option for your new package, `configure' will
-probably detect the previously built and installed `libintl' library
-and will decide to use it.  If not, you may have to to use the
-`--with-libintl-prefix' option to tell `configure' where to look for it.
-
-   Internationalized packages usually have many `po/LL.po' files, where
-LL gives an ISO 639 two-letter code identifying the language.  Unless
-translations have been forbidden at `configure' time by using the
-`--disable-nls' switch, all available translations are installed
-together with the package.  However, the environment variable `LINGUAS'
-may be set, prior to configuration, to limit the installed set.
-`LINGUAS' should then contain a space separated list of two-letter
-codes, stating which languages are allowed.
-
-1.2 Using This Package
-======================
-
-As a user, if your language has been installed for this package, you
-only have to set the `LANG' environment variable to the appropriate
-`LL_CC' combination.  If you happen to have the `LC_ALL' or some other
-`LC_xxx' environment variables set, you should unset them before
-setting `LANG', otherwise the setting of `LANG' will not have the
-desired effect.  Here `LL' is an ISO 639 two-letter language code, and
-`CC' is an ISO 3166 two-letter country code.  For example, let's
-suppose that you speak German and live in Germany.  At the shell
-prompt, merely execute `setenv LANG de_DE' (in `csh'),
-`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
-This can be done from your `.login' or `.profile' file, once and for
-all.
-
-   You might think that the country code specification is redundant.
-But in fact, some languages have dialects in different countries.  For
-example, `de_AT' is used for Austria, and `pt_BR' for Brazil.  The
-country code serves to distinguish the dialects.
-
-   The locale naming convention of `LL_CC', with `LL' denoting the
-language and `CC' denoting the country, is the one use on systems based
-on GNU libc.  On other systems, some variations of this scheme are
-used, such as `LL' or `LL_CC.ENCODING'.  You can get the list of
-locales supported by your system for your language by running the
-command `locale -a | grep '^LL''.
-
-   Not all programs have translations for all languages.  By default, an
-English message is shown in place of a nonexistent translation.  If you
-understand other languages, you can set up a priority list of languages.
-This is done through a different environment variable, called
-`LANGUAGE'.  GNU `gettext' gives preference to `LANGUAGE' over `LANG'
-for the purpose of message handling, but you still need to have `LANG'
-set to the primary language; this is required by other parts of the
-system libraries.  For example, some Swedish users who would rather
-read translations in German than English for when Swedish is not
-available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
-
-   Special advice for Norwegian users: The language code for Norwegian
-bokma*l changed from `no' to `nb' recently (in 2003).  During the
-transition period, while some message catalogs for this language are
-installed under `nb' and some older ones under `no', it's recommended
-for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and
-older translations are used.
-
-   In the `LANGUAGE' environment variable, but not in the `LANG'
-environment variable, `LL_CC' combinations can be abbreviated as `LL'
-to denote the language's main dialect.  For example, `de' is equivalent
-to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
-(Portuguese as spoken in Portugal) in this context.
-
-1.3 Translating Teams
-=====================
-
-For the Free Translation Project to be a success, we need interested
-people who like their own language and write it well, and who are also
-able to synergize with other translators speaking the same language.
-Each translation team has its own mailing list.  The up-to-date list of
-teams can be found at the Free Translation Project's homepage,
-`http://translationproject.org/', in the "Teams" area.
-
-   If you'd like to volunteer to _work_ at translating messages, you
-should become a member of the translating team for your own language.
-The subscribing address is _not_ the same as the list itself, it has
-`-request' appended.  For example, speakers of Swedish can send a
-message to `sv-request@li.org', having this message body:
-
-     subscribe
-
-   Keep in mind that team members are expected to participate
-_actively_ in translations, or at solving translational difficulties,
-rather than merely lurking around.  If your team does not exist yet and
-you want to start one, or if you are unsure about what to do or how to
-get started, please write to `coordinator@translationproject.org' to
-reach the coordinator for all translator teams.
-
-   The English team is special.  It works at improving and uniformizing
-the terminology in use.  Proven linguistic skills are praised more than
-programming skills, here.
-
-1.4 Available Packages
-======================
-
-Languages are not equally supported in all packages.  The following
-matrix shows the current state of internationalization, as of June
-2010.  The matrix shows, in regard of each package, for which languages
-PO files have been submitted to translation coordination, with a
-translation percentage of at least 50%.

-   Some counters in the preceding matrix are higher than the number of
-visible blocks let us expect.  This is because a few extra PO files are
-used for implementing regional variants of languages, or language
-dialects.
-
-   For a PO file in the matrix above to be effective, the package to
-which it applies should also have been internationalized and
-distributed as such by its maintainer.  There might be an observable
-lag between the mere existence a PO file and its wide availability in a
-distribution.

-   If June 2010 seems to be old, you may fetch a more recent copy of
-this `ABOUT-NLS' file on most GNU archive sites.  The most up-to-date
-matrix with full percentage details can be found at

-1.5 Using `gettext' in new packages
-===================================
-
-If you are writing a freely available program and want to
-internationalize it you are welcome to use GNU `gettext' in your
-package.  Of course you have to respect the GNU Library General Public
-License which covers the use of the GNU `gettext' library.  This means
-in particular that even non-free programs can use `libintl' as a shared
-library, whereas only free software can use `libintl' as a static
-library or use modified versions of `libintl'.
-
-   Once the sources are changed appropriately and the setup can handle
-the use of `gettext' the only thing missing are the translations.  The
-Free Translation Project is also available for packages which are not
-developed inside the GNU project.  Therefore the information given above
-applies also for every other Free Software Project.  Contact
-`coordinator@translationproject.org' to make the `.pot' files available
-to the translation teams.

-
-2020-01-19  Paul Smith  <psmith@gnu.org>
-
-	[SV 40657] Reinstate old behavior for suffix rules with prereqs
-	POSIX says that suffix rules cannot have prerequisites, but after
-	making this change we observed a number of makefiles "in the wild"
-	that were relying on this behavior and failed.
-
-	For .POSIX: makefiles, obey POSIX.  Otherwise preserve the old
-	behavior.  However, generate a warning so users know this is a
-	problem.  In a future version we will change all behavior to be
-	POSIX-conforming.
-
-	* NEWS: describe the change
-	* src/rule.c (convert_to_pattern): If posix_pedantic don't make a
-	pattern rule if prereqs exist.  Otherwise show a warning.
-	* tests/scripts/features/suffixrules: Add tests for the new behavior
-	including .POSIX vs. non-.POSIX.
-
-2020-01-05  Dmitry Goncharov  <dgoncharov@users.sf.net>

-
-	* doc/make.texi: Change the GFDL to an Appendix
-
-	* NEWS: Clarify authorship of new features.
-
-	Enable compilation with C90 compilers
-	* configure.ac: Try compiling Guile headers: they don't work with C90.
-	* maintMakefile: Simplify config checks via target-specific variables.
-	* src/makeint.h: Use ATTRIBUTE rather than defining __attribute__,
-	as that causes compile issues with system headers.
-	(ENUM_BITFIELD): Don't use enum bitfields in ANSI mode.
-	* src/main.c: Use ATTRIBUTE instead of __attribute__.
-	* src/job.h: Ditto.
-	* src/file.c: Don't define variables inside for loops.
-	* src/rule.c: Ditto.
-	* src/dep.h (SI): Only use static inline in non-ANSI mode.

-	* src/dep.h (struct dep): New flag to note extra prereq deps.
-	* src/filedef.h (expand_extra_prereqs): Declare a function to expand
-	the value of .EXTRA_PREREQS.
-	* src/file.c (expand_extra_prereqs): Given a struct variable lookup
-	of .EXTRA_PREREQS, convert it into a list of deps and for each one
-	make sure it has a struct file and has the new flag set.
-	(snap_file): A new function invoked by hash_map that will perform
-	per-file operations: set up second expansion, intermediate, and also
-	.EXTRA_PREREQS.  Manage circular dependencies by ignoring them.
-	(snap_deps): Defer per-file operations until the end.  Look up the
-	global .EXTRA_PREREQS and pass it along to snap_file for each file.
-	* src/implicit.c (struct patdeps): Remember the extra prereqs flag.
-	(pattern_search): Transfer extra prereqs flag settings into the
-	matched pattern rule.
-	* src/rule.h (snap_implicit_rules): Rename count_implicit_rules to
-	snap_implicit_rules since we now do more than count.
-	* src/rule.c (snap_implicit_rules): As we walk through all the pattern
-	rules, add in any global .EXTRA_PREREQS to the dep list.  Ensure we
-	take them into account for the max number of prereqs and name length.
-	* src/main.c (main): Add extra-prereqs to .FEATURES.

-2019-12-27  Paul Smith  <psmith@gnu.org>
-
-	[SV 57022] Avoid posix_spawn which fails asynchronously
-	Avoid using posix_spawn implementations that fail asynchronously when
-	the spawned program can't be invoked: this means instead of getting
-	an error such as "No such file or directory" we get just "Exit 127".
-
-	Original implementation of the configure.ac macro provided by
-	Martin Dorey <martin.dorey@hds.com>
-
-	Original implementation of the regression tests provided by
-	Dmitry Goncharov <dgoncharov@users.sf.net>
-
-	* configure.ac: Test whether posix_spawn fails asynchronously.  In a

-	that it does, fall back to fork/exec.
-	* tests/scripts/features/exec: Add regression tests for different

-
-2019-12-18  Jouke Witteveen  <j.witteveen@gmail.com>
-
-	[SV 54161] Fix second expansion of $* for paths
-	If the stem matches a path containing a directory not just a
-	filename, make sure the second expansion of $* in the
-	prerequisites matches $* in the recipe.  This requires using
-	$(*F) when replacing % in the first expansion to preserve the
-	simple filename.
-
-	* src/implicit.c (pattern_search): If lastslash is set prepend
-	the directory onto the stem.  Then use $(*F) when expanding %.
-	* tests/scripts/features/se_implicit: Add a test case
-
-2019-12-17  Jouke Witteveen  <j.witteveen@gmail.com>
-
-	* src/implicit.c (pattern_search): Set lastslash correctly
-	If filename contained multiple slashes lastslash is wrongly set to 0.
-	* configure.ac: Check for the GNU memrchr() extension function.
-	* src/misc.c (memrchr): Supply memrchr() if not available.

-	* src/implicit.c (pattern-search): Remove unneeded 'dir' variable
-
-2019-12-17  Paul Smith  <psmith@gnu.org>
-
-	* Makefile.am: Build lzip package instead of bzip2
-	* README.git: Mention changed requirements.
-
-	* src/job.c (load_too_high): Disable Linux /proc/loadavg for now
-	This new feature has a problem: if you provide a load which is
-	larger than the number of cores then it will always run every job.
-	Before we can enable it we need to at the least learn how to clamp
-	this value to the number of cores.  To experiment with it, set
-	PROC_FD_INIT to -2 in job.c to re-enable the feature.
-
-	* tests/run_make_tests.pl (set_more_defaults): Fix typo
-
-2019-12-16  Paul Smith  <psmith@gnu.org>
-
-	* tests/run_make_tests.pl (subst_make_string): Force use of /
-	On Windows the path to the helper tool will contain '\': this will
-	fail if recipes are run with a POSIX shell.  Convert '\' to '/'
-	on Windows.  While here, escape any spaces in the path as well.
-
-	Rename jhelp.pl to thelp.pl and make it a generic test helper.
-	* tests/thelp.pl: Rename from tests/jhelp.pl.
-	(op): Use names instead of options for the operations.
-	(op): Add new operations for sleep, mkdir, and rm.
-	(op): Enhance wait to time out
-	* tests/run_make_tests.pl: Add a new #HELPER# replacement
-	(subst_make_string): Use fully-qualified path to thelp.pl
-	* tests/scripts/features/parallelism: Update to use thelp.pl
-	and the new named operations.  Use thelp.pl sleep instead of
-	system-specific sleep commands.
-	* tests/scripts/features/output-sync: Update to use thelp.pl
-	instead of complex shell scripts.
-	* Makefile.am: Distribute tests/thelp.pl instead of tests/jhelp.pl
-
-2019-10-10  Paul Eggert  <eggert@cs.ucla.edu>
-
-	Port functions/shell test to Solaris 10
-	* tests/scripts/functions/shell: Port exit-status calculation
-	to Solaris 10 with Perl 5.8.4.
-
-2019-10-08  Paul Smith  <psmith@gnu.org>
-
-	Release GNU make 4.2.92

-	* tests/scripts/features/archives: Call get_config() rather than
-	using %CONFIG_FLAGS directly.
-	* tests/scripts/features/load: Ditto.
-	* tests/scripts/features/loadapi: Ditto.
-	* tests/scripts/functions/wildcard: Ditto.
-
-	* src/hash.c (jhash_string): Don't read past end of string.

-	This reverts commit 6264deece3bb77798240a906ceed79097adbcf48.
-	Further investigation discovers that the real issue is that
-	GNU Emacs compile mode doesn't have a matching regex for GNU
-	make error messages generated when targets fail.  I submitted
-	a patch to GNU Emacs adding a matcher for compile mode.
-
-2019-09-21  Paul Smith  <psmith@gnu.org>

-	This reverts commit 38e96eadea6e2cd42a0f414959bac327de9f468a.
-	Per discussion on Savannah, the modified behavior matches

-	[SV 56834] Support local PATH search with posix_spawnp
-	When using exec we install the child's environment before invoking
-	execlp(), so commands are found on the child's PATH.  posix_spawnp
-	searches on the parent's PATH, which we don't want.
-
-	Import gnulib's findprog-in module and use it to search the child's
-	PATH, then use posix_spawn() to run it.
-
-	Also, posix_spawn() does not fall back to trying sh on ENOEXEC, as
-	execlp() does, so implement that as well.
-
-	* bootstrap.conf: Add the findprog-in gnulib module
-	* src/job.c: Include findprog.h if we're using posix_spawn.
-	(start_job_command): Remove the handling of child->cmd_name,
-	(child_execute_job): and add it here.  Look up the command to be
-	run in the child's path and invoke it if found.  If it fails with
-	ENOEXEC then retry it as an argument to the default shell.
-	* tests/scripts/misc/general4: Test makefile PATH assignments.
-	* tests/scripts/features/targetvars: Ditto, for target variables.

-	work so well on systems where we don't fork at all.  Instead, treat

-	* src/dir.c: Preserve glob d_type field
-	When using GNU make on a system with glibc glob a pattern ending in
-	a slash is also matching regular files, but only in subdirectories:
-
-	$ mkdir -p dir/subdir
-	$ cd dir
-	$ touch file1 subdir/file2
-	$ echo 'test:; @echo $(wildcard */ */*/)' | make -f -
-	subdir/ subdir/file2
-	$ echo 'test: */ */*/; @echo "$?" != */ */*/' | make -f -
-	subdir/ subdir/file2 != subdir/ */*/
-
-	It happens because in the gl->gl_readdir callback supplied to glob(),
-	dirent->d_type is set to DT_UNKNOWN, and the glob() implementation
-	in glibc assumes that such a directory entry *cannot* possibly be a
-	regular file.
-
-	Pass the actual d_type down to glob(); this is the right thing to do
-	even if glibc is fixed, because it saves an extra stat() syscall for
-	each dirent.

-
-	Remove unsupported build facilities.
-	Over time the non-standard build and install systems (nmake files,
-	smake files, Visual Studio project files, etc.) have atrophied and
-	maintaining them is not worth the effort, for such a simple utility
-	as make.  Remove all the non-standard build tool support and unify
-	OS-specific build rules under a basic set of (GNU make) makefiles.
-
-	Preserve the existing bootstrapping scripts (for POSIX, Windows,
-	and MS-DOS).  Also the existing VMS build scripts are left unchanged:
-	I don't have enough experience with VMS to venture into this area.
-	Perhaps one of the VMS maintainers might like to determine whether
-	conversion would be appropriate.
-
-	Rather than create libraries for w32 and glob (non-POSIX), simply
-	link the object files directly to remove the complexity.
-
-	* NEWS: Update with user-facing notes.
-	* Makefile.am: Clean up to use the latest automake best practices.
-	Build Windows code directly from the root makefile to avoid recursion.

-
-	Do not use STOP_SET for singleton compares.
-	Compare against '$' directly rather than using MAP_VARIABLE.
-	This saves ~10% for find_map_function, which is the top hotspot in
-	QEMU's no-op build.  The build is sped up overall by about 1.5%
-	more (from 11.1s to 10.95s).
-
-	* read.c (find_map_function): Do not compare against singleton sets.
-
-2017-11-11  Paolo Bonzini  <pbonzini@redhat.com>
-
-	Speedup parsing of functions.
-	Use the stopchar map to quickly jump over everything that is
-	not an open/close brace, an open/close parenthesis or a comma.
-
-	This saves 1% on QEMU's noop build (from 11.23s to 11.1s).
-
-	* function.c (find_next_argument, handle_function): Check
-	with STOP_SET before comparing against individual characters.
-	* main.c (initialize_stopchar_map): Initialize MAP_VARSEP
-	mappings in stopchar_map.
-	* makeint.h (MAP_VARSEP): New.

-
-	Remove MAP_PERCENT as strchr is faster.
-	* read.c (find_percent_cached): Use strchr instead of STOP_SET

-	* main.c (initialize_stopchar_map): Remove.
-
-2017-11-11  Paolo Bonzini  <pbonzini@redhat.com>
-
-	Use Jenkins hash.
-	This is about twice as fast as the current hash, and removes the
-	need for double hashing (improving locality of reference).  The
-	hash function is based on Bob Jenkins' design, slightly adapted
-	wherever Make needs to hash NUL-terminated strings.  The old hash
-	function is kept for case-insensitive hashing.
-
-	This saves 8.5% on QEMU's no-op build (from 12.87s to 11.78s).
-
-	* configure.ac: Check endianness.
-	* hash.c (rol32, jhash_mix, jhash_final, JHASH_INITVAL,
-	sum_get_unaligned_32, jhash): New.
-	* hash.h (STRING_HASH_1, STRING_N_HASH_1): Use jhash.
-	(STRING_HASH_2, STRING_N_HASH_2): Return a dummy value.
-	(STRING_N_COMPARE, return_STRING_N_COMPARE): Prefer memcmp to strncmp.
-
-2017-11-11  Paolo Bonzini  <pbonzini@redhat.com>
-
-	Use strchr for simple case of find_char_unquote.
-	In most cases, find_char_unquote has a single stopchar.  In that
-	case we can look for it using strchr's optimized implementation.
-
-	This saves 3.5% on QEMU's noop build (from 11.78s to 11.37s).
-
-	* read.c (find_char_unquote): Rename to find_map_unquote.  Replace
-	with an implementation optimized for the case where the stopchar
-	is a singleton.  Adjust all callers.
-
-2017-11-11  Paolo Bonzini  <pbonzini@redhat.com>
-
-	Use strchr/memmove in collapse_continuations.
-	collapse_continuations is already using strchr to speed up the
-	common case of no backslash-newline sequence, but on modern
-	processors it is faster to scan the string twice with
-	strchr+memmove (or strlen+memmove) than to move bytes manually.
-
-	Saves about 1.5% on QEMU's no-op build (from 11.37s to 11.23s).
-
-	* misc.c (collapse_continuations): Rewrite the scanning of LINE.

-	glob: Do not assume glibc glob internals.
-	It has been proposed that glibc glob start using gl_lstat,
-	which the API allows it to do.  GNU 'make' should not get in

-
-	[SV 47995] Ensure forced double-colon rules work with -j.
-	The fix for SV 44742 had a side-effect that some double-colon targets
-	were skipped.  This happens because the "considered" facility assumed
-	that all targets would be visited on each walk through the dependency
-	graph: we used a bit for considered and toggled it on each pass; if
-	we didn't walk the entire graph on every pass the bit would get out
-	of sync.  The new behavior after SV 44742 might return early without
-	walking the entire graph.  To fix this I changed the considered value
-	to an integer which is monotonically increasing: it is then never
-	possible to incorrectly determine that a previous pass through the
-	graph already considered the current target.
-
-	* filedef.h (struct file): make CONSIDERED an unsigned int.
-	* main.c (main): No longer need to reset CONSIDERED.
-	* remake.c (update_goal_chain): increment CONSIDERED rather than

-
-	[SV 45728] Detect changes in .VARIABLES more accurately.
-	For performance, we only recompute .VARIABLES when (a) it's expanded

-	you undefine and redefine the same number of entries in between
-	expanding .VARIABLES, it doesn't detect any change.  Instead, keep
-	an increasing change number.

-	Also pselect() supports a timeout so avoid alarm() calls.
-
-	Clean up some compiler warnings.

-
-	* tests/scripts/features/archives: Handle deterministic archives.
-	Newer versions of binutils allow ar to be compiled to generate
-	"deterministic archives" by default: in this mode no timestamp
-	information is generated in the static archive, which utterly
-	breaks GNU make's archive updating capability.  Debian and Ubuntu
-	have turned this feature on by default in their distributions
-	which causes the regression tests to fail.
-
-	Update the regression tests to check for the availability of the
-	"U" option to ar which disables deterministic archives and allows
-	GNU make's archive support to work properly again.

-
-	* implicit.c (pattern_search): [SV 43677] Mark files secondary.
-	In order to fix SV 12267 we were marking the prerequisites of
-	implicit (pattern) targets that existed elsewhere in the makefile
-	as precious to keep them from being deleted as intermediate files.
-	However this also keeps them from being deleted on error.  Instead

-	implementation was incomplete.  Instead, create a one-off large
-	string cache entry and add it directly to the full cache list
-	without changing the default buffer size.

-
-2015-01-27  John Malmberg  <wb8tyw@qsl.net>
-
-	Fix bs-nl handling, exit and Environment for VMS.
-	This fix required a complete rewrite of the command parser vmsjobs.c
-	child_execute_job.  The old parser had too many incorrect assumptions
-	about DCL commands and could not be repaired to extended.
-
-	The parser now more closely parses VMS commands and handles quoted
-	commands and redirection.  Command File mode has been improved, but can
-	not fully support bs-nl syntax.
-
-	VMS Unix shell simulation has been improved.
-
-	* commands.c: vms_comma_separator is now a run-time setting.
-	* function.c: vms_comma_separator is now a run-time setting.
-	* function.c(func_basename_dir) now reports "[]" or "./" based on
-	  VMS crtl runtime setting.
-	* job.c(start_job_command): VMS Handle empty commands propery.
-	* main.c: Add VMS environment variables for run-time settings.
-	  * vms_legacy_behavior - Force older behavior.

-	* readme.vms: Update to current behavior.
-	* variable.c(define_variable_in_set): Fix VMS Environment variable
-	  lookup.
-	* variable.c(define_automatic_variables): Remove some VMS specific
-	  automatic variables and use the Unix ones instead.
-	* vms_export_symbol.c: Set max symbol size correctly.
-	* vmsjobs.c: child_execute_job() complete rewrite of VMS comand
-	  parsing.

-2014-10-20  John Malmberg  <wb8tyw@qsl.net>
-
-	Fix VMS implicit rules and UNIX paths.
-	This fixes VMS implicit rules and UNIX style pathname handling.
-	It also fixes some of the VMS style pathname handling, more work
-	there will be needed later.
-	TODO: There are other case insensitive platforms besides VMS.
-	We need to find out why there is extra VMS code for this.  This
-	indicates either the extra VMS code is not needed, or the case
-	insensitive support may not be complete on the other case
-	insensitive platforms.
-
-	* default.c: Add missing definitions to default_suffix_rules[] and
-	default_variables[].
-	TODO: As it is important that VMS DCL mode definitions must always
-	be a superset of UNIX definitions, a better way of maintaining the
-	VMS DCL mode definitions should be devised.
-	* dir.c (downcase_inplace): Add a reentrant downcase() routine.
-	Add future support for VMS 8.2+ _USE_STD_STAT macro which will
-	disable a lot of VMS specific code from compiling.
-	(dir_file_exists_p): vmsify filename only if directory name has VMS
-	directory delimiters.
-	(file_exists_p): Handle both VMS and UNIX directories.

-
-	[SV 42447]: VMS simulate exporting symbols
-	This also includes fixing the most of the exit handling code for VMS.
-
-	Self tests:
-	 Previously about 94 Tests in 36 categories fail.
-	 Now about 45 tests in 22 categories fail.
-
-	Because some tests do not properly clean up, the number of tests that
-	fail can vary by one or two test cases between consecutive runs.
-
-	* Makefile.am: Add new VMS files.
-	* job.c: add prototype for vms_strsignal().
-	* job.c: (child_error): Remove VMS specific code as no longer needed.

-	status to 0 instead of setting it to the proper exit status.
-	* job.h: Add vms_launch_status to struct child.
-	* main.c: (main): Use environment variables for options to use MCR
-	* instead of a foreign command, and to always use command files for
-	subprocesses.
-	For VMS use (set_program_name) routine which is common to ports of
-	other GNU packages to VMS to set the program name used internally.
-	Use (vms_putenv_symbol) to set up symbols to be visible in child
-	programs, including recursive make launched by execve()
-	Start of Bash shell detection code for VMS.
-	* makefile.com: Need nested_include=none for building on VMS search
-	lists.  Add vms_progname, vms_exit, and vms_export_symbol.
-	* makefile.vms: Need nested_include=none for building on VMS search
-	lists.  Add vms_progname, vms_exit, vms_export_symbol.
-	* makeint.h: Make sure non-standard "VMS" macro is defined.  Add
-	prototypes for new VMS routines.  Remove VMS-specific failure codes.
-	* vmsjobs.c: Add VMS POSIX exit code constants.
-	(_is_unixy_shell): Detect Bash shell.
-	(vms_strsignal): simulate strsignal() on VMS.

-	child and restore afterward unless option to use command files for
-	subprocesses is set.  Improve handling of UNIX null commands ":".
-	* vms_exit.c: Provides vms_exit() to detect if an exit code is UNIX
-	or VMS, and converts the UNIX code into a VMS exit code.
-	* vms_export_symbol.c: Routines to create DCL symbols that work like
-	shell aliases or exported shell symbols and clean them up on exit.
-	* vms_export_symbol_test.com: Unit test for vms_export_symbol.c
-	* vms_progname.c: New file: VMS specific replace for progname.c that

-	run from the VMS DCL Interpreter.  When the tests are run from GNV
-	on VMS, the $port_type will be 'UNIX'.
-	* run_make_tests.com: VMS search list support.  This is needed for
-	using a search list such as prj_root = lcl_root:,vms_root:,src_root:
-	for building and testing.

-	enables forced DCL symbol substitution in the actions.
-
-	Fix VMS automatic variable expansion

-
-	Fix MinGW64 problem with non-compliant vsnprintf.
-	 makeint.h (__USE_MINGW_ANSI_STDIO) [__MINGW64_VERSION_MAJOR]:

-	 implementation of vsnprintf.  Reported by Christian Boos
-	 <cboos@edgewall.org>.
-
-	Fix the MSVC build on MS-Windows.
-	 output.c (vsnprintf) [_MSC_VER]: Define, instead of defining

-	Add makefile rules for updating the http://www.gnu.org/software/make
-	web pages, including the online GNU make manual.
-
-	Convert to auto-generated ChangeLog files.
-	Rename existing ChangeLog files so they won't be distributed.
-	Add targets to maintMakefile to generate ChangeLog from the Git
-	repository.  This will require a version of gnulib be available.
-	Because ChangeLog is auto-generated, we have to switch our
-	automake mode to "foreign" or it will complain and fail.
-
-	Set up for the next release.

-Version 4.3 (19 Jan 2020)
-
-A complete list of bugs fixed in this version is available here:
-
-https://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=108&set=custom
-
-* WARNING: Backward-incompatibility!
-  Number signs (#) appearing inside a macro reference or function invocation
-  no longer introduce comments and should not be escaped with backslashes:
-  thus a call such as:
-    foo := $(shell echo '#')
-  is legal.  Previously the number sign needed to be escaped, for example:
-    foo := $(shell echo '\#')
-  Now this latter will resolve to "\#".  If you want to write makefiles
-  portable to both versions, assign the number sign to a variable:
-    H := \#
-    foo := $(shell echo '$H')
-  This was claimed to be fixed in 3.81, but wasn't, for some reason.
-  To detect this change search for 'nocomment' in the .FEATURES variable.
-
-* WARNING: Backward-incompatibility!
-  Previously appending using '+=' to an empty variable would result in a value
-  starting with a space.  Now the initial space is only added if the variable
-  already contains some value.  Similarly, appending an empty string does not
-  add a trailing space.
-
-* NOTE: Deprecated behavior.
-  Contrary to the documentation, suffix rules with prerequisites are being
-  treated BOTH as simple targets AND as pattern rules.  Further, the
-  prerequisites are ignored by the pattern rules.  POSIX specifies that in
-  order to be a suffix rule there can be no prerequisites defined.  In this
-  release if POSIX mode is enabled then rules with prerequisites cannot be
-  suffix rules.  If POSIX mode is not enabled then the previous behavior is
-  preserved (a pattern rule with no extra prerequisites is created) AND a
-  warning about this behavior is generated:
-    warning: ignoring prerequisites on suffix rule definition
-  The POSIX behavior will be adopted as the only behavior in a future release
-  of GNU make so please resolve any warnings.
-
-* New feature: Grouped explicit targets
-  Pattern rules have always had the ability to generate multiple targets with
-  a single invocation of the recipe.  It's now possible to declare that an
-  explicit rule generates multiple targets with a single invocation.  To use
-  this, replace the ":" token with "&:" in the rule.  To detect this feature
-  search for 'grouped-target' in the .FEATURES special variable.
-  Implementation contributed by Kaz Kylheku <kaz@kylheku.com>
-
-* New feature: .EXTRA_PREREQS variable
-  Words in this variable are considered prerequisites of targets but they are
-  not added to any of the automatic variable values when expanding the
-  recipe.  This variable can either be global (applies to all targets) or
-  a target-specific variable.  To detect this feature search for 'extra-prereqs'
-  in the .FEATURES special variable.
-  Implementation contributed by Christof Warlich <cwarlich@gmx.de>
-
-* Makefiles can now specify the '-j' option in their MAKEFLAGS variable and
-  this will cause make to enable that parallelism mode.
-
-* GNU make will now use posix_spawn() on systems where it is available.
-  If you prefer to use fork/exec even on systems where posix_spawn() is
-  present, you can use the --disable-posix-spawn option to configure.
-  Implementation contributed by Aron Barath <baratharon@caesar.elte.hu>
-
-* Error messages printed when invoking non-existent commands have been cleaned
-  up and made consistent.
-
-* The previous limit of 63 jobs under -jN on MS-Windows is now
-  increased to 4095.  That limit includes the subprocess started by
-  the $(shell) function.
-
-* A new option --no-silent has been added, that cancels the effect of the
-  -s/--silent/--quiet flag.
-
-* A new option -E has been added as a short alias for --eval.
-
-* All wildcard expansion within GNU make, including $(wildcard ...), will sort
-  the results.  See https://savannah.gnu.org/bugs/index.php?52076
-
-* Interoperate with newer GNU libc and musl C runtime libraries.
-
-* Performance improvements provided by Paolo Bonzini <pbonzini@redhat.com>
-
-GNU make Developer News
-
-* Import the GNU standard bootstrap script to replace the hand-rolled
-  "make update" method for building code from a GNU make Git repository.
-
-* Rework the source distribution to move source files into the src/*
-  subdirectory.  This aligns with modern best practices in GNU.
-
-* Replace local portability code with Gnulib content.  Unfortunately due to a
-  problem with Gnulib support for getloadavg, this forces a requirement on
-  Automake 1.16 or above in order to build from Git.  See README.git.

-Version 4.2 (22 May 2016)
-
-A complete list of bugs fixed in this version is available here:
-
-https://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=106&set=custom
-
-* New variable: $(.SHELLSTATUS) is set to the exit status of the last != or
-  $(shell ...) function invoked in this instance of make.  This will be "0" if
-  successful or not "0" if not successful.  The variable value is unset if no
-  != or $(shell ...) function has been invoked.
-
-* The $(file ...) function can now read from a file with $(file <FILE).
-  The function is expanded to the contents of the file.  The contents are
-  expanded verbatim except that the final newline, if any, is stripped.
-
-* The makefile line numbers shown by GNU make now point directly to the
-  specific line in the recipe where the failure or warning occurred.
-  Sample changes suggested by Brian Vandenberg <phantall@gmail.com>
-
-* The interface to GNU make's "jobserver" is stable as documented in the
-  manual, for tools which may want to access it.
-
-  WARNING: Backward-incompatibility! The internal-only command line option
-  --jobserver-fds has been renamed for publishing, to --jobserver-auth.
-
-* The amount of parallelism can be determined by querying MAKEFLAGS, even when
-  the job server is enabled (previously MAKEFLAGS would always contain only
-  "-j", with no number, when job server was enabled).
-
-* VMS-specific changes:
-
-  * Perl test harness now works.
-
-  * Full support for converting Unix exit status codes to VMS exit status
-    codes.  BACKWARD INCOMPATIBILITY Notice: On a child failure the VMS exit
-    code is now the encoded Unix exit status that Make usually generates, not
-    the VMS exit status of the child.

-Version 4.1 (05 Oct 2014)
-
-A complete list of bugs fixed in this version is available here:
-
-https://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=105&set=custom
-
-* New variables: $(MAKE_TERMOUT) and $(MAKE_TERMERR) are set to non-empty
-  values if stdout or stderr, respectively, are believed to be writing to a
-  terminal.  These variables are exported by default.
-
-* Allow a no-text-argument form of the $(file ...) function.  Without a text
-  argument nothing is written to the file: it is simply opened in the
-  requested mode, then closed again.
-
-* Change the fatal error for mixed explicit and implicit rules, that was
-  introduced in GNU make 3.82, to a non-fatal error.  However, this syntax is
-  still deprecated and may return to being illegal in a future version of GNU
-  make.  Makefiles that rely on this syntax should be fixed.
-  See https://savannah.gnu.org/bugs/?33034
-
-* VMS-specific changes:
-
-  * Support for library files added, including support for using the GNV ar
-    utility.
-
-  * Partial support for properly encoding Unix exit status codes into VMS exit
-    status codes.
-
-    WARNING: Backward-incompatibility! These are different exit status codes
-    than Make exited with in the past.
-
-  * Macros to hold the current make command are set up to translate the
-    argv[0] string to a VMS format path name and prefix it with "MCR " so that
-    the macro has a space in it.
-
-    WARNING: Backward-incompatibility!  This may break complex makefiles that
-    do processing on those macros.  This is unlikely because so much in that
-    area was not and is still not currently working on VMS, it is unlikely to
-    find such a complex makefile, so this is more likely to impact
-    construction of a future makefile.
-
-  * A command file is always used to run the commands for a recipe.
-
-    WARNING: Backward-incompatibility!  Running the make self tests has
-    exposed that there are significant differences in behavior when running
-    with the command file mode.  It is unknown if this will be noticed by most
-    existing VMS makefiles.
-
-Version 4.0 (09 Oct 2013)
-
-A complete list of bugs fixed in this version is available here:
-
-https://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=101&set=custom
-
-* WARNING: Backward-incompatibility!
-  If .POSIX is specified, then make adheres to the POSIX backslash/newline
-  handling requirements, which introduces the following changes to the
-  standard backslash/newline handling in non-recipe lines:
-  * Any trailing space before the backslash is preserved
-  * Each backslash/newline (plus subsequent whitespace) is converted to a
-    single space
-
-* New feature: GNU Guile integration
-  This version of GNU make can be compiled with GNU Guile integration.
-  GNU Guile serves as an embedded extension language for make.
-  See the "Guile Function" section in the GNU Make manual for details.
-  Currently GNU Guile 1.8 and 2.0+ are supported.  In Guile 1.8 there is no
-  support for internationalized character sets.  In Guile 2.0+, scripts can be
-  encoded in UTF-8.
-
-* New command line option: --output-sync (-O) enables grouping of output by
-  target or by recursive make.  This is useful during parallel builds to avoid
-  mixing output from different jobs together giving hard-to-understand
-  results.  Original implementation by David Boyce <dsb@boyski.com>.
-  Reworked and enhanced by Frank Heckenbach <f.heckenbach@fh-soft.de>.
-  Windows support by Eli Zaretskii <eliz@gnu.org>.
-
-* New command line option: --trace enables tracing of targets.  When enabled
-  the recipe to be invoked is printed even if it would otherwise be suppressed
-  by .SILENT or a "@" prefix character.  Also before each recipe is run the
-  makefile name and linenumber where it was defined are shown as well as the
-  prerequisites that caused the target to be considered out of date.
-
-* New command line option argument: --debug now accepts a "n" (none) flag
-  which disables all debugging settings that are currently enabled.
-
-* New feature: The "job server" capability is now supported on Windows.
-  Implementation contributed by Troy Runkel <Troy.Runkel@mathworks.com>
-
-* New feature: The .ONESHELL capability is now supported on Windows.  Support
-  added by Eli Zaretskii <eliz@gnu.org>.
-
-* New feature: "!=" shell assignment operator as an alternative to the
-  $(shell ...) function.  Implemented for compatibility with BSD makefiles.
-  Note there are subtle differences between "!=" and $(shell ...).  See the
-  description in the GNU make manual.
-  WARNING: Backward-incompatibility!
-  Variables ending in "!" previously defined as "variable!= value" will now be
-  interpreted as shell assignment.  Change your assignment to add whitespace
-  between the "!" and "=": "variable! = value"
-
-* New feature: "::=" simple assignment operator as defined by POSIX in 2012.
-  This operator has identical functionality to ":=" in GNU make, but will be
-  portable to any implementation of make conforming to a sufficiently new
-  version of POSIX (see http://austingroupbugs.net/view.php?id=330).  It is
-  not necessary to define the .POSIX target to access this operator.
-
-* New feature: Loadable objects
-  This version of GNU make contains a "technology preview": the ability to
-  load dynamic objects into the make runtime.  These objects can be created by
-  the user and can add extended functionality, usable by makefiles.
-
-* New function: $(file ...) writes to a file.
-
-* New variable: $(GNUMAKEFLAGS) will be parsed for make flags, just like
-  MAKEFLAGS is.  It can be set in the environment or the makefile, containing
-  GNU make-specific flags to allow your makefile to be portable to other
-  versions of make.  Once this variable is parsed, GNU make will set it to the
-  empty string so that flags will not be duplicated on recursion.
-
-* New variable: `MAKE_HOST' gives the name of the host architecture
-  make was compiled for.  This is the same value you see after 'Built for'
-  when running 'make --version'.
-
-* Behavior of MAKEFLAGS and MFLAGS is more rigorously defined.  All simple
-  flags are grouped together in the first word of MAKEFLAGS.  No options that
-  accept arguments appear in the first word.  If no simple flags are present
-  MAKEFLAGS begins with a space.  Flags with both short and long versions
-  always use the short versions in MAKEFLAGS.  Flags are listed in
-  alphabetical order using ASCII ordering.  MFLAGS never begins with "- ".
-
-* Setting the -r and -R options in MAKEFLAGS inside a makefile now works as
-  expected, removing all built-in rules and variables, respectively.
-
-* If a recipe fails, the makefile name and linenumber of the recipe are shown.
-
-* A .RECIPEPREFIX setting is remembered per-recipe and variables expanded
-  in that recipe also use that recipe prefix setting.
-
-* In -p output, .RECIPEPREFIX settings are shown and all target-specific
-  variables are output as if in a makefile, instead of as comments.
-
-* On MS-Windows, recipes that use ".." quoting will no longer force
-  invocation of commands via temporary batch files and stock Windows
-  shells, they will be short-circuited and invoked directly.  (In
-  other words, " is no longer a special character for stock Windows
-  shells.)  This avoids hitting shell limits for command length when
-  quotes are used, but nothing else in the command requires the shell.
-  This change could potentially mean some minor incompatibilities in
-  behavior when the recipe uses quoted string on shell command lines.
-

-Version 3.82 (28 Jul 2010)
-
-A complete list of bugs fixed in this version is available here:
-
-https://sv.gnu.org/bugs/index.php?group=make&report_id=111&fix_release_id=104&set=custom
-
-* Compiling GNU make now requires a conforming ISO C 1989 compiler and
-  standard runtime library.
-
-* WARNING: Backward-incompatibility!
-  The POSIX standard for make was changed in the 2008 version in a
-  fundamentally incompatible way: make is required to invoke the shell as if
-  the '-e' flag were provided.  Because this would break many makefiles that
-  have been written to conform to the original text of the standard, the
-  default behavior of GNU make remains to invoke the shell with simply '-c'.
-  However, any makefile specifying the .POSIX special target will follow the
-  new POSIX standard and pass '-e' to the shell.  See also .SHELLFLAGS
-  below.
-
-* WARNING: Backward-incompatibility!
-  The '$?' variable now contains all prerequisites that caused the target to
-  be considered out of date, even if they do not exist (previously only
-  existing targets were provided in $?).
-
-* WARNING: Backward-incompatibility!
-  Wildcards were not documented as returning sorted values, but the results
-  have been sorted up until this release..  If your makefiles require sorted
-  results from wildcard expansions, use the $(sort ...)  function to request
-  it explicitly.
-
-* WARNING: Backward-incompatibility!
-  As a result of parser enhancements, three backward-compatibility issues
-  exist: first, a prerequisite containing an "=" cannot be escaped with a
-  backslash any longer.  You must create a variable containing an "=" and
-  use that variable in the prerequisite.  Second, variable names can no
-  longer contain whitespace, unless you put the whitespace in a variable and
-  use the variable.  Third, in previous versions of make it was sometimes
-  not flagged as an error for explicit and pattern targets to appear in the
-  same rule.  Now this is always reported as an error.
-
-* WARNING: Backward-incompatibility!
-  The pattern-specific variables and pattern rules are now applied in the
-  shortest stem first order instead of the definition order (variables
-  and rules with the same stem length are still applied in the definition
-  order). This produces the usually-desired behavior where more specific
-  patterns are preferred. To detect this feature search for 'shortest-stem'
-  in the .FEATURES special variable.
-
-* WARNING: Backward-incompatibility!
-  The library search behavior has changed to be compatible with the standard
-  linker behavior. Prior to this version for prerequisites specified using
-  the -lfoo syntax make first searched for libfoo.so in the current
-  directory, vpath directories, and system directories. If that didn't yield
-  a match, make then searched for libfoo.a in these directories. Starting
-  with this version make searches first for libfoo.so and then for libfoo.a
-  in each of these directories in order.
-
-* New command line option: --eval=STRING causes STRING to be evaluated as
-  makefile syntax (akin to using the $(eval ...) function).  The evaluation
-  is performed after all default rules and variables are defined, but before
-  any makefiles are read.
-
-* New special variable: .RECIPEPREFIX allows you to reset the recipe
-  introduction character from the default (TAB) to something else.  The
-  first character of this variable value is the new recipe introduction
-  character.  If the variable is set to the empty string, TAB is used again.
-  It can be set and reset at will; recipes will use the value active when
-  they were first parsed.  To detect this feature check the value of
-  $(.RECIPEPREFIX).
-
-* New special variable: .SHELLFLAGS allows you to change the options passed
-  to the shell when it invokes recipes.  By default the value will be "-c"
-  (or "-ec" if .POSIX is set).
-
-* New special target: .ONESHELL instructs make to invoke a single instance
-  of the shell and provide it with the entire recipe, regardless of how many
-  lines it contains.  As a special feature to allow more straightforward
-  conversion of makefiles to use .ONESHELL, any recipe line control
-  characters ('@', '+', or '-') will be removed from the second and
-  subsequent recipe lines.  This happens _only_ if the SHELL value is deemed
-  to be a standard POSIX-style shell.  If not, then no interior line control
-  characters are removed (as they may be part of the scripting language used
-  with the alternate SHELL).
-
-* New variable modifier 'private': prefixing a variable assignment with the
-  modifier 'private' suppresses inheritance of that variable by
-  prerequisites.  This is most useful for target- and pattern-specific
-  variables.
-
-* New make directive: 'undefine' allows you to undefine a variable so that
-  it appears as if it was never set. Both $(flavor) and $(origin) functions
-  will return 'undefined' for such a variable. To detect this feature search
-  for 'undefine' in the .FEATURES special variable.
-
-* The parser for variable assignments has been enhanced to allow multiple
-  modifiers ('export', 'override', 'private') on the same line as variables,
-  including define/endef variables, and in any order.  Also, it is possible
-  to create variables and targets named as these modifiers.
-
-* The 'define' make directive now allows a variable assignment operator
-  after the variable name, to allow for simple, conditional, or appending
-  multi-line variable assignment.
-
-* VMS-specific changes:
-
-  * Michael Gehre (at VISTEC-SEMI dot COM) supplied a fix for a problem with
-    timestamps of object modules in OLBs. The timestamps were not correctly
-    adjusted to GMT based time, if the local VMS time was using a daylight
-    saving algorithm and if daylight saving was switched off.
-
-  * John Eisenbraun (at HP dot COM) supplied fixes and and an enhancement to
-    append output redirection in action lines.
-
-  * Rework of ctrl+c and ctrl+y handling.
-
-  * Fix a problem with cached strings, which showed on case-insensitive file
-    systems.
-
-  * Build fixes for const-ified code in VMS specific sources.
-
-  * A note on appending the redirected output. With this change, a simple
-    mechanism is implemented to make ">>" work in action lines. In VMS
-    there is no simple feature like ">>" to have DCL command or program
-    output redirected and appended to a file. GNU make for VMS already
-    implements the redirection of output. If such a redirection is detected,
-    an ">" on the action line, GNU make creates a DCL command procedure to
-    execute the action and to redirect its output. Based on that, now ">>"
-    is also recognized and a similar but different command procedure is
-    created to implement the append. The main idea here is to create a
-    temporary file which collects the output and which is appended to the
-    wanted output file. Then the temporary file is deleted. This is all done
-    in the command procedure to keep changes in make small and simple. This
-    obviously has some limitations but it seems good enough compared with
-    the current ">" implementation. (And in my opinion, redirection is not
-    really what GNU make has to do.) With this approach, it may happen that
-    the temporary file is not yet appended and is left in SYS$SCRATCH.
-    The temporary file names look like "CMDxxxxx.". Any time the created
-    command procedure can not complete, this happens. Pressing Ctrl+Y to
-    abort make is one case. In case of Ctrl+Y the associated command
-    procedure is left in SYS$SCRATCH as well. Its name is CMDxxxxx.COM.
-
-  * Change in the Ctrl+Y handling. The CtrlY handler now uses $delprc to
-    delete all children. This way also actions with DCL commands will be
-    stopped. As before the CtrlY handler then sends SIGQUIT to itself,
-    which is handled in common code.
-
-  * Change in deleteing temporary command files. Temporary command files
-    are now deleted in the vms child termination handler. That deletes
-    them even if a Ctrl+C was pressed.
-
-  * The behavior of pressing Ctrl+C is not changed. It still has only an
-    effect, after the current action is terminated. If that doesn't happen
-    or takes too long, Ctrl+Y should be used instead.
-

-Version 3.81 (01 Apr 2006)
-
-* GNU make is ported to OS/2.
-
-* GNU make is ported to MinGW.  The MinGW build is only supported by
-  the build_w32.bat batch file; see the file README.W32 for more
-  details.
-
-* WARNING: Future backward-incompatibility!
-  Up to and including this release, the '$?' variable does not contain
-  any prerequisite that does not exist, even though that prerequisite
-  might have caused the target to rebuild.  Starting with the _next_
-  release of GNU make, '$?' will contain all prerequisites that caused
-  the target to be considered out of date.
-  See https://savannah.gnu.org/bugs/?16051
-
-* WARNING: Backward-incompatibility!
-  GNU make now implements a generic "second expansion" feature on the
-  prerequisites of both explicit and implicit (pattern) rules.  In order
-  to enable this feature, the special target '.SECONDEXPANSION' must be
-  defined before the first target which takes advantage of it.  If this
-  feature is enabled then after all rules have been parsed the
-  prerequisites are expanded again, this time with all the automatic
-  variables in scope.  This means that in addition to using standard
-  SysV $$@ in prerequisites lists, you can also use complex functions
-  such as $$(notdir $$@) etc.  This behavior applies to implicit rules,
-  as well, where the second expansion occurs when the rule is matched.
-  However, this means that when '.SECONDEXPANSION' is enabled you must
-  double-quote any "$" in your filenames; instead of "foo: boo$$bar" you
-  now must write "foo: foo$$$$bar".  Note that the SysV $$@ etc. feature,
-  which used to be available by default, is now ONLY available when the
-  .SECONDEXPANSION target is defined.  If your makefiles take advantage
-  of this SysV feature you will need to update them.
-
-* WARNING: Backward-incompatibility!
-  In order to comply with POSIX, the way in which GNU make processes
-  backslash-newline sequences in recipes has changed.  If your makefiles
-  use backslash-newline sequences inside of single-quoted strings in
-  recipes you will be impacted by this change.  See the GNU make manual
-  subsection "Splitting Recipe Lines" (node "Splitting Lines"), in
-  section "Recipe Syntax", chapter "Writing Recipe in Rules", for
-  details.
-
-* WARNING: Backward-incompatibility!
-  Some previous versions of GNU make had a bug where "#" in a function
-  invocation such as $(shell ...) was treated as a make comment.  A
-  workaround was to escape these with backslashes.  This bug has been
-  fixed: if your makefile uses "\#" in a function invocation the
-  backslash is now preserved, so you'll need to remove it.
-
-* New command line option: -L (--check-symlink-times).  On systems that
-  support symbolic links, if this option is given then GNU make will
-  use the most recent modification time of any symbolic links that are
-  used to resolve target files.  The default behavior remains as it
-  always has: use the modification time of the actual target file only.
-
-* The "else" conditional line can now be followed by any other valid
-  conditional on the same line: this does not increase the depth of the
-  conditional nesting, so only one "endif" is required to close the
-  conditional.
-
-* All pattern-specific variables that match a given target are now used
-  (previously only the first match was used).
-
-* Target-specific variables can be marked as exportable using the
-  "export" keyword.
-
-* In a recursive $(call ...) context, any extra arguments from the outer
-  call are now masked in the context of the inner call.
-
-* Implemented a solution for the "thundering herd" problem with "-j -l".
-  This version of GNU make uses an algorithm suggested by Thomas Riedl
-  <thomas.riedl@siemens.com> to track the number of jobs started in the
-  last second and artificially adjust GNU make's view of the system's
-  load average accordingly.
-
-* New special variables available in this release:
-   - .INCLUDE_DIRS: Expands to a list of directories that make searches
-     for included makefiles.
-   - .FEATURES: Contains a list of special features available in this
-     version of GNU make.
-   - .DEFAULT_GOAL: Set the name of the default goal make will
-     use if no goals are provided on the command line.
-   - MAKE_RESTARTS: If set, then this is the number of times this
-     instance of make has been restarted (see "How Makefiles Are Remade"
-     in the manual).
-   - New automatic variable: $| (added in 3.80, actually): contains all
-     the order-only prerequisites defined for the target.
-
-* New functions available in this release:
-   - $(lastword ...) returns the last word in the list.  This gives
-     identical results as $(word $(words ...) ...), but is much faster.
-   - $(abspath ...) returns the absolute path (all "." and ".."
-     directories resolved, and any duplicate "/" characters removed) for
-     each path provided.
-   - $(realpath ...) returns the canonical pathname for each path
-     provided.  The canonical pathname is the absolute pathname, with
-     all symbolic links resolved as well.
-   - $(info ...) prints its arguments to stdout.  No makefile name or
-     line number info, etc. is printed.
-   - $(flavor ...) returns the flavor of a variable.
-   - $(or ...) provides a short-circuiting OR conditional: each argument
-     is expanded.  The first true (non-empty) argument is returned; no
-     further arguments are expanded.  Expands to empty if there are no
-     true arguments.
-   - $(and ...) provides a short-circuiting AND conditional: each
-     argument is expanded.  The first false (empty) argument is
-     returned; no further arguments are expanded.  Expands to the last
-     argument if all arguments are true.
-
-* Changes made for POSIX compatibility:
-   - Only touch targets (under -t) if they have a recipe.
-   - Setting the SHELL make variable does NOT change the value of the
-     SHELL environment variable given to programs invoked by make.  As
-     an enhancement to POSIX, if you export the make variable SHELL then
-     it will be set in the environment, just as before.
-
-* On MS Windows systems, explicitly setting SHELL to a pathname ending
-  in "cmd" or "cmd.exe" (case-insensitive) will force GNU make to use
-  the DOS command interpreter in batch mode even if a UNIX-like shell
-  could be found on the system.
-
-* On VMS there is now support for case-sensitive filesystems such as ODS5.
-  See the README.VMS file for information.
-
-* Parallel builds (-jN) no longer require a working Bourne shell on
-  Windows platforms.  They work even with the stock Windows shells, such
-  as cmd.exe and command.com.
-
-* Updated to autoconf 2.59, automake 1.9.5, and gettext 0.14.1.  Users
-  should not be impacted.
-
-* New translations for Swedish, Chinese (simplified), Ukrainian,
-  Belarusian, Finnish, Kinyarwandan, and Irish.  Many updated
-  translations.

-
-
-Version 3.80 (03 Oct 2002)
-
-* A new feature exists: order-only prerequisites.  These prerequisites
-  affect the order in which targets are built, but they do not impact
-  the rebuild/no-rebuild decision of their dependents.  That is to say,
-  they allow you to require target B be built before target A, without
-  requiring that target A will always be rebuilt if target B is updated.
-  Patch for this feature provided by Greg McGary <greg@mcgary.org>.
-
-* For compatibility with SysV make, GNU make now supports the peculiar
-  syntax $$@, $$(@D), and $$(@F) in the prerequisites list of a rule.
-  This syntax is only valid within explicit and static pattern rules: it
-  cannot be used in implicit (suffix or pattern) rules.  Edouard G. Parmelan
-  <egp@free.fr> provided a patch implementing this feature; however, I
-  decided to implement it in a different way.
-
-* The argument to the "ifdef" conditional is now expanded before it's
-  tested, so it can be a constructed variable name.
-
-  Similarly, the arguments to "export" (when not used in a variable
-  definition context) and "unexport" are also now expanded.
-
-* A new function is defined: $(value ...).  The argument to this
-  function is the _name_ of a variable.  The result of the function is
-  the value of the variable, without having been expanded.
-
-* A new function is defined: $(eval ...).  The arguments to this
-  function should expand to makefile commands, which will then be
-  evaluated as if they had appeared in the makefile.  In combination
-  with define/endef multiline variable definitions this is an extremely
-  powerful capability.  The $(value ...) function is also sometimes
-  useful here.
-
-* A new built-in variable is defined, $(MAKEFILE_LIST).  It contains a
-  list of each makefile GNU make has read, or started to read, in the
-  order in which they were encountered.  So, the last filename in the
-  list when a makefile is just being read (before any includes) is the
-  name of the current makefile.
-
-* A new built-in variable is defined: $(.VARIABLES).  When it is
-  expanded it returns a complete list of variable names defined by all
-  makefiles at that moment.
-
-* A new command line option is defined, -B or --always-make.  If
-  specified GNU make will consider all targets out-of-date even if they
-  would otherwise not be.
-
-* The arguments to $(call ...) functions were being stored in $1, $2,
-  etc. as recursive variables, even though they are fully expanded
-  before assignment.  This means that escaped dollar signs ($$ etc.)
-  were not behaving properly.  Now the arguments are stored as simple
-  variables.  This may mean that if you added extra escaping to your
-  $(call ...) function arguments you will need to undo it now.
-
-* The variable invoked by $(call ...) can now be recursive: unlike other
-  variables it can reference itself and this will not produce an error
-  when it is used as the first argument to $(call ...) (but only then).
-
-* New pseudo-target .LOW_RESOLUTION_TIME, superseding the configure
-  option --disable-nsec-timestamps.  You might need this if your build
-  process depends on tools like "cp -p" preserving time stamps, since
-  "cp -p" (right now) doesn't preserve the subsecond portion of a time
-  stamp.
-
-* Updated translations for French, Galician, German, Japanese, Korean,
-  and Russian.  New translations for Croatian, Danish, Hebrew, and
-  Turkish.
-
-* Updated internationalization support to Gettext 0.11.5.
-  GNU make now uses Gettext's "external" feature, and does not include
-  any internationalization code itself.  Configure will search your
-  system for an existing implementation of GNU Gettext (only GNU Gettext
-  is acceptable) and use it if it exists.  If not, NLS will be disabled.
-  See ABOUT-NLS for more information.
-
-* Updated to autoconf 2.54 and automake 1.7.  Users should not be impacted.
-
-* VMS-specific changes:
-
-  * In default.c define variable ARCH as IA64 for VMS on Itanium systems.
-
-  * In makefile.vms avoid name collision for glob and globfree.
-
-  * This is the VMS port of GNU Make done by Hartmut.Becker@compaq.com.
-
-    It is based on the specific version 3.77k and on 3.78.1. 3.77k was done
-    by Klaus K�mpf <kkaempf@rmi.de>, the code was based on the VMS port of
-    GNU Make 3.60 by Mike Moretti.
-
-    It was ported on OpenVMS/Alpha V7.1, DECC V5.7-006. It was re-build and
-    tested on OpenVMS/Alpha V7.2, OpenVMS/VAX 7.1 and 5.5-2. Different
-    versions of DECC were used. VAXC was tried: it fails; but it doesn't
-    seem worth to get it working. There are still some PTRMISMATCH warnings
-    during the compile. Although perl is working on VMS the test scripts
-    don't work. The function $shell is still missing.
-
-    There is a known bug in some of the VMS CRTLs. It is in the shipped
-    versions of VMS V7.2 and V7.2-1 and in the currently (October 1999)
-    available ECOs for VMS V7.1 and newer versions. It is fixed in versions
-    shipped with newer VMS versions and all ECO kits after October 1999. It
-    only shows up during the daylight saving time period (DST): stat()
-    returns a modification time 1 hour ahead. This results in GNU make
-    warning messages. For a just created source you will see:
-
-     $ gmake x.exe
-     gmake.exe;1: *** Warning: File 'x.c' has modification time in the future
-     (940582863 > 940579269)
-     cc    /obj=x.obj x.c
-     link  x.obj    /exe=x.exe
-     gmake.exe;1: *** Warning:  Clock skew detected.  Your build may be
-     incomplete.

-
-
-Version 3.79.1 (23 Jun 2000)
-
-* .SECONDARY with no prerequisites now prevents any target from being
-  removed because make thinks it's an intermediate file, not just those
-  listed in the makefile.
-
-* New configure option --disable-nsec-timestamps, but this was
-  superseded in later versions by the .LOW_RESOLUTION_TIME pseudo-target.
-
-Version 3.79 (04 Apr 2000)
-
-* GNU make optionally supports internationalization and locales via the
-  GNU gettext (or local gettext if suitable) package.  See the ABOUT-NLS
-  file for more information on configuring GNU make for NLS.
-
-* Previously, GNU make quoted variables such as MAKEFLAGS and
-  MAKEOVERRIDES for proper parsing by the shell.  This allowed them to
-  be used within make build scripts.  However, using them there is not
-  proper behavior: they are meant to be passed to subshells via the
-  environment.  Unfortunately the values were not quoted properly to be
-  passed through the environment.  This meant that make didn't properly
-  pass some types of command line values to submakes.
-
-  With this version we change that behavior: now these variables are
-  quoted properly for passing through the environment, which is the
-  correct way to do it.  If you previously used these variables
-  explicitly within a make rule you may need to re-examine your use for
-  correctness given this change.
-
-* A new pseudo-target .NOTPARALLEL is available.  If defined, the
-  current makefile is run serially regardless of the value of -j.
-  However, submakes are still eligible for parallel execution.
-
-* The --debug option has changed: it now allows optional flags
-  controlling the amount and type of debugging output.  By default only
-  a minimal amount information is generated, displaying the names of
-  "normal" targets (not makefiles) that were deemed out of date and in
-  need of being rebuilt.
-
-  Note that the -d option behaves as before: it takes no arguments and
-  all debugging information is generated.
-
-* The `-p' (print database) output now includes filename and linenumber
-  information for variable definitions, to aid debugging.
-
-* The wordlist function no longer reverses its arguments if the "start"
-  value is greater than the "end" value.  If that's true, nothing is
-  returned.
-
-* Hartmut Becker provided many updates for the VMS port of GNU make.
-  See the README.VMS file for more details.
-
-* VMS-specific changes:
-
-  * Fix a problem with automatically remaking makefiles. GNU make uses an
-    execve to restart itself after a successful remake of the makefile. On
-    UNIX systems execve replaces the running program with a new one and
-    resets all signal handling to the default. On VMS execve creates a child
-    process, signal and exit handlers of the parent are still active, and,
-    unfortunately, corrupt the exit code from the child. Fix in job.c:
-    ignore SIGCHLD.
-
-  * Added some switches to reflect latest features of DECC. Modifications in
-    makefile.vms.
-
-  * Set some definitions to reflect latest features of DECC. Modifications in
-    config.h-vms (which is copied to config.h).
-
-  * Added extern strcmpi declaration to avoid 'implicitly declared' messages.
-    Modification in make.h.
-
-  * Default rule for C++, conditionals for gcc (GCC_IS_NATIVE) or DEC/Digital/
-    Compaq c/c++ compilers. Modifications in default.c.
-
-  * Usage of opendir() and friends, suppress file version. Modifications in
-    dir.c.
-
-  * Added VMS specific code to handle ctrl+c and ctrl+y to abort make.
-    Modifications in job.c.
-
-  * Added support to have case sensitive targets and dependencies but to
-    still use case blind file names. This is especially useful for Java
-    makefiles on VMS:
-
-        .SUFFIXES :
-        .SUFFIXES : .class .java
-        .java.class :
-                javac "$<
-        HelloWorld.class :      HelloWorld.java
-
-  * A new macro WANT_CASE_SENSITIVE_TARGETS in config.h-vms was introduced.
-    It needs to be enabled to get this feature; default is disabled.  The
-    macro HAVE_CASE_INSENSITIVE_FS must not be touched: it is still enabled.
-    Modifications in file.c and config.h-vms.
-
-  * Bootstrap make to start building make is still makefile.com, but make
-    needs to be re-made with a make to make a correct version: ignore all
-    possible warnings, delete all objects, rename make.exe to a different
-    name and run it.
-
-  * Made some minor modifications to the bootstrap build makefile.com.
-
-Version 3.78 (22 Sep 1999)
-
-* Two new functions, $(error ...) and $(warning ...) are available.  The
-  former will cause make to fail and exit immediately upon expansion of
-  the function, with the text provided as the error message.  The latter
-  causes the text provided to be printed as a warning message, but make
-  proceeds normally.
-
-* A new function $(call ...) is available.  This allows users to create
-  their own parameterized macros and invoke them later.  Original
-  implementation of this function was provided by Han-Wen Nienhuys
-  <hanwen@cs.uu.nl>.
-
-* A new function $(if ...) is available.  It provides if-then-else
-  capabilities in a builtin function.  Original implementation of this
-  function was provided by Han-Wen Nienhuys <hanwen@cs.uu.nl>.
-
-* Make defines a new variable, .LIBPATTERNS.  This variable controls how
-  library dependency expansion (dependencies like ``-lfoo'') is performed.
-
-* Make accepts CRLF sequences as well as traditional LF, for
-  compatibility with makefiles created on other operating systems.
-
-* Make accepts a new option: -R, or --no-builtin-variables.  This option
-  disables the definition of the rule-specific builtin variables (CC,
-  LD, AR, etc.).  Specifying this option forces -r (--no-builtin-rules)
-  as well.
-
-* A "job server" feature, suggested by Howard Chu <hyc@highlandsun.com>.
-
-  On systems that support POSIX pipe(2) semantics, GNU make can now pass
-  -jN options to submakes rather than forcing them all to use -j1.  The
-  top make and all its sub-make processes use a pipe to communicate with
-  each other to ensure that no more than N jobs are started across all
-  makes.  To get the old behavior of -j back, you can configure make
-  with the --disable-job-server option.
-
-* The confusing term "dependency" has been replaced by the more accurate
-  and standard term "prerequisite", both in the manual and in all GNU make
-  output.
-
-* GNU make supports the "big archive" library format introduced in AIX 4.3.
-
-* GNU make supports large files on AIX, HP-UX, and IRIX.  These changes
-  were provided by Paul Eggert <eggert@twinsun.com>.  (Large file
-  support for Solaris and Linux was introduced in 3.77, but the
-  configuration had issues: these have also been resolved).
-
-* The Windows 95/98/NT (W32) version of GNU make now has native support
-  for the Cygnus Cygwin release B20.1 shell (bash).
-
-* The GNU make regression test suite, long available separately "under
-  the table", has been integrated into the release.  You can invoke it
-  by running "make check" in the distribution.  Note that it requires
-  Perl (either Perl 4 or Perl 5) to run.
-
-Version 3.77 (28 Jul 1998)
-
-* Implement BSD make's "?=" variable assignment operator.  The variable
-  is assigned the specified value only if that variable is not already
-  defined.
-
-* Make defines a new variable, "CURDIR", to contain the current working
-  directory (after the -C option, if any, has been processed).
-  Modifying this variable has no effect on the operation of make.
-
-* Make defines a new default RCS rule, for new-style master file
-  storage: ``% :: RCS/%'' (note no ``,v'' suffix).
-
-  Make defines new default rules for DOS-style C++ file naming
-  conventions, with ``.cpp'' suffixes.  All the same rules as for
-  ``.cc'' and ``.C'' suffixes are provided, along with LINK.cpp and
-  COMPILE.cpp macros (which default to the same value as LINK.cc and
-  COMPILE.cc).  Note CPPFLAGS is still C preprocessor flags!  You should
-  use CXXFLAGS to change C++ compiler flags.
-
-* A new feature, "target-specific variable values", has been added.
-  This is a large change so please see the appropriate sections of the
-  manual for full details.  Briefly, syntax like this:
-
-    TARGET: VARIABLE = VALUE
-
-  defines VARIABLE as VALUE within the context of TARGET.  This is
-  similar to SunOS make's "TARGET := VARIABLE = VALUE" feature.  Note
-  that the assignment may be of any type, not just recursive, and that
-  the override keyword is available.
-
-  COMPATIBILITY: This new syntax means that if you have any rules where
-  the first or second dependency has an equal sign (=) in its name,
-  you'll have to escape them with a backslash: "foo : bar\=baz".
-  Further, if you have any dependencies which already contain "\=",
-  you'll have to escape both of them: "foo : bar\\\=baz".
-
-* A new appendix listing the most common error and warning messages
-  generated by GNU make, with some explanation, has been added to the
-  GNU make User's Manual.
-
-* Updates to the GNU make Customs library support (see README.customs).
-
-* Updates to the Windows 95/NT port from Rob Tulloh (see README.W32),
-  and to the DOS port from Eli Zaretski (see README.DOS).
-
-* VMS-specific changes:
-
-  * This is the VMS port of GNU Make.
-    It is based on the VMS port of GNU Make 3.60 by Mike Moretti.
-    This port was done by Klaus K�mpf <kkaempf@rmi.de>
-
-  * There is first-level support available from proGIS Software, Germany.
-    Visit their web-site at http://www.progis.de to get information
-    about other vms software and forthcoming updates to gnu make.
-
-  * /bin/sh style I/O redirection is supported. You can now write lines like
-        mcr sys$disk:[]program.exe < input.txt > output.txt &> error.txt
-
-  * Makefile variables are looked up in the current environment. You can set
-    symbols or logicals in DCL and evaluate them in the Makefile via
-    $(<name-of-symbol-or-logical>).  Variables defined in the Makefile
-    override VMS symbols/logicals !
-
-  * Functions for file names are working now. See the GNU Make manual for
-    $(dir ...)  and $(wildcard ...).  Unix-style and VMS-style names are
-    supported as arguments.
-
-  * The default rules are set up for GNU C. Building an executable from a
-    single source file is as easy as 'make file.exe'.
-
-  * The variable $(ARCH) is predefined as ALPHA or VAX resp. Makefiles for
-    different VMS systems can now be written by checking $(ARCH) as in
-      ifeq ($(ARCH),ALPHA)
-        $(ECHO) "On the Alpha"
-      else
-        $(ECHO) "On the VAX"
-      endif
-
-  * Command lines of excessive length are correctly broken and written to a
-    batch file in sys$scratch for later execution. There's no limit to the
-    lengths of commands (and no need for .opt files :-) any more.
-
-  * Empty commands are handled correctly and don't end in a new DCL process.
-
-Version 3.76.1 (19 Sep 1997)
-
-* Small (but serious) bug fix.  Quick rollout to get into the GNU source CD.
-
-Version 3.76 (16 Sep 1997)
-
-* GNU make now uses automake to control Makefile.in generation.  This
-  should make it more consistent with the GNU standards.
-
-* VPATH functionality has been changed to incorporate the VPATH+ patch,
-  previously maintained by Paul Smith <psmith@baynetworks.com>.  See the
-  manual.
-
-* Make defines a new variable, `MAKECMDGOALS', to contain the goals that
-  were specified on the command line, if any.  Modifying this variable
-  has no effect on the operation of make.
-
-* A new function, `$(wordlist S,E,TEXT)', is available: it returns a
-  list of words from number S to number E (inclusive) of TEXT.
-
-* Instead of an error, detection of future modification times gives a
-  warning and continues.  The warning is repeated just before GNU make
-  exits, so it is less likely to be lost.
-
-* Fix the $(basename) and $(suffix) functions so they only operate on
-  the last filename, not the entire string:
-
-      Command              Old Result             New Result
-      -------              ----------             ----------
-    $(basename a.b)        a                      a
-    $(basename a.b/c)      a                      a.b/c
-    $(suffix a.b)          b                      b
-    $(suffix a.b/c)        b/c                    <empty>
-
-* The $(strip) function now removes newlines as well as TABs and spaces.
-
-* The $(shell) function now changes CRLF (\r\n) pairs to a space as well
-  as newlines (\n).
-
-* Updates to the Windows 95/NT port from Rob Tulloh (see README.W32).
-
-* Eli Zaretskii has updated the port to 32-bit protected mode on MSDOS
-  and MS-Windows, building with the DJGPP v2 port of GNU C/C++ compiler
-  and utilities.  See README.DOS for details, and direct all questions
-  concerning this port to Eli Zaretskii <eliz@is.elta.co.il> or DJ
-  Delorie <dj@delorie.com>.
-
-* VMS-specific changes:
-
-  * John W. Eaton has updated the VMS port to support libraries and VPATH.
-
-  * The cd command is supported if it's called as $(CD). This invokes
-    the 'builtin_cd' command which changes the directory.
-    Calling 'set def' doesn't do the trick, since a sub-shell is
-    spawned for this command, the directory is changed *in this sub-shell*
-    and the sub-shell ends.
-
-  * Libraries are not supported. They were in GNU Make 3.60 but somehow I
-    didn't care porting the code. If there is enough interest, I'll do it at
-    some later time.
-
-  * The variable $^ separates files with commas instead of spaces (It's the
-    natural thing to do for VMS).
-
-  * See defaults.c for VMS default suffixes and my definitions for default
-    rules and variables.
-
-  * The shell function is not implemented yet.
-
-  * Load average routines haven't been implemented for VMS yet.
-
-  * The default include directory for including other makefiles is
-    SYS$SYSROOT:[SYSLIB] (I don't remember why I didn't just use
-    SYS$LIBRARY: instead; maybe it wouldn't work that way).
-
-  * The default makefiles make looks for are: makefile.vms, gnumakefile,
-    makefile., and gnumakefile. .
-
-  * The stat() function and handling of time stamps in VMS is broken, so I
-    replaced it with a hack in vmsfunctions.c. I will provide a full rewrite
-    somewhere in the future. Be warned, the time resolution inside make is
-    less than what vms provides. This might be a problem on the faster Alphas.
-
-  * You can use a : in a filename only if you precede it with a backslash ('\').
-    E.g.- hobbes\:[bogas.files]
-
-  * Make ignores success, informational, or warning errors (-S-, -I-, or -W-).
-    But it will stop on -E- and -F- errors. (unless you do something
-    to override this in your makefile, or whatever).
-
-  * Remote stuff isn't implemented yet.
-
-  * Multiple line DCL commands, such as "if" statements, must be put inside
-    command files.  You can run a command file by using \@.
-
-Version 3.75 (27 Aug 1996)
-
-* The directory messages printed by `-w' and implicitly in sub-makes,
-  are now omitted if Make runs no commands and has no other messages to print.
-
-* Make now detects files that for whatever reason have modification times
-  in the future and gives an error.  Files with such impossible timestamps
-  can result from unsynchronized clocks, or archived distributions
-  containing bogus timestamps; they confuse Make's dependency engine
-  thoroughly.
-
-* The new directive `sinclude' is now recognized as another name for
-  `-include', for compatibility with some other Makes.
-
-* Aaron Digulla has contributed a port to AmigaDOS.  See README.Amiga for
-  details, and direct all Amiga-related questions to <digulla@fh-konstanz.de>.
-
-* Rob Tulloh of Tivoli Systems has contributed a port to Windows NT or 95.
-  See README.W32 for details, and direct all Windows-related questions to
-  <rob_tulloh@tivoli.com>.
-
-* VMS-specific changes:
-
-  * Lots of default settings are adapted for VMS. See default.c.
-
-  * Long command lines are now converted to command files.
-
-  * Comma (',') as a separator is now allowed. See makefile.vms for an example.
-
-Version 3.73 (05 Apr 1995)
-
-* Converted to use Autoconf version 2, so `configure' has some new options.
-  See INSTALL for details.
-
-* You can now send a SIGUSR1 signal to Make to toggle printing of debugging
-  output enabled by -d, at any time during the run.
-
-Version 3.72 (04 Nov 1994)
-
-* DJ Delorie has ported Make to MS-DOS using the GO32 extender.
-  He is maintaining the DOS port, not the GNU Make maintainer;
-  please direct bugs and questions for DOS to <djgpp@sun.soe.clarkson.edu>.
-  MS-DOS binaries are available for FTP from ftp.simtel.net in
-  /pub/simtelnet/gnu/djgpp/.
-
-* The `MAKEFLAGS' variable (in the environment or in a makefile) can now
-  contain variable definitions itself; these are treated just like
-  command line variable definitions.  Make will automatically insert any
-  variable definitions from the environment value of `MAKEFLAGS' or from
-  the command line, into the `MAKEFLAGS' value exported to children.  The
-  `MAKEOVERRIDES' variable previously included in the value of `$(MAKE)'
-  for sub-makes is now included in `MAKEFLAGS' instead.  As before, you can
-  reset `MAKEOVERRIDES' in your makefile to avoid putting all the variables
-  in the environment when its size is limited.
-
-* If `.DELETE_ON_ERROR' appears as a target, Make will delete the target of
-  a rule if it has changed when its recipe exits with a nonzero status,
-  just as when the recipe gets a signal.
-
-* The automatic variable `$+' is new.  It lists all the dependencies like
-  `$^', but preserves duplicates listed in the makefile.  This is useful
-  for linking rules, where library files sometimes need to be listed twice
-  in the link order.
-
-* You can now specify the `.IGNORE' and `.SILENT' special targets with
-  dependencies to limit their effects to those files.  If a file appears as
-  a dependency of `.IGNORE', then errors will be ignored while running the
-  recipe to update that file.  Likewise if a file appears as a dependency
-  of `.SILENT', then the recipe to update that file will not be printed
-  before it is run.  (This change was made to conform to POSIX.2.)
-
-Version 3.71 (21 May 1994)
-
-* The automatic variables `$(@D)', `$(%D)', `$(*D)', `$(<D)', `$(?D)', and
-  `$(^D)' now omit the trailing slash from the directory name.  (This change
-  was made to comply with POSIX.2.)
-
-* The source distribution now includes the Info files for the Make manual.
-  There is no longer a separate distribution containing Info and DVI files.
-
-* You can now set the variables `binprefix' and/or `manprefix' in
-  Makefile.in (or on the command line when installing) to install GNU make
-  under a name other than `make' (i.e., ``make binprefix=g install''
-  installs GNU make as `gmake').
-
-* The built-in Texinfo rules use the new variables `TEXI2DVI_FLAGS' for
-  flags to the `texi2dvi' script, and `MAKEINFO_FLAGS' for flags to the
-  Makeinfo program.
-
-* The exit status of Make when it runs into errors is now 2 instead of 1.
-  The exit status is 1 only when using -q and some target is not up to date.
-  (This change was made to comply with POSIX.2.)
-
-Version 3.70 (03 Jan 1994)
-
-* It is no longer a fatal error to have a NUL character in a makefile.
-  You should never put a NUL in a makefile because it can have strange
-  results, but otherwise empty lines full of NULs (such as produced by
-  the `xmkmf' program) will always work fine.
-
-* The error messages for nonexistent included makefiles now refer to the
-  makefile name and line number where the `include' appeared, so Emacs's
-  C-x ` command takes you there (in case it's a typo you need to fix).
-
-Version 3.69 (07 Nov 1993)
-
-* Implicit rule search for archive member references is now done in the
-  opposite order from previous versions: the whole target name `LIB(MEM)'
-  first, and just the member name and parentheses `(MEM)' second.
-
-* Make now gives an error for an unterminated variable or function reference.
-  For example, `$(foo' with no matching `)' or `${bar' with no matching `}'.
-
-* The new default variable `MAKE_VERSION' gives the version number of
-  Make, and a string describing the remote job support compiled in (if any).
-  Thus the value (in this release) is something like `3.69' or `3.69-Customs'.
-
-* Commands in an invocation of the `shell' function are no longer run
-  with a modified environment like recipes are.  As in versions before
-  3.68, they now run with the environment that `make' started with.  We
-  have reversed the change made in version 3.68 because it turned out to
-  cause a paradoxical situation in cases like:
-
-        export variable = $(shell echo value)
-
-  When Make attempted to put this variable in the environment for a
-  recipe, it would try expand the value by running the shell command
-  `echo value'.  In version 3.68, because it constructed an environment
-  for that shell command in the same way, Make would begin to go into an
-  infinite loop and then get a fatal error when it detected the loop.
-
-* The recipe given for `.DEFAULT' is now used for phony targets with no
-  recipe.
-
-Version 3.68 (28 Jul 1993)
-
-* You can list several archive member names inside parenthesis:
-  `lib(mem1 mem2 mem3)' is equivalent to `lib(mem1) lib(mem2) lib(mem3)'.
-
-* You can use wildcards inside archive member references.  For example,
-  `lib(*.o)' expands to all existing members of `lib' whose names end in
-  `.o' (e.g. `lib(a.o) lib(b.o)'); `*.a(*.o)' expands to all such members
-  of all existing files whose names end in `.a' (e.g. `foo.a(a.o)
-  foo.a(b.o) bar.a(c.o) bar.a(d.o)'.
-
-* A suffix rule `.X.a' now produces two pattern rules:
-        (%.o): %.X	# Previous versions produced only this.
-        %.a: %.X	# Now produces this as well, just like other suffixes.
-
-* The new flag `--warn-undefined-variables' says to issue a warning message
-  whenever Make expands a reference to an undefined variable.
-
-* The new `-include' directive is just like `include' except that there is
-  no error (not even a warning) for a nonexistent makefile.
-
-* Commands in an invocation of the `shell' function are now run with a
-  modified environment like recipes are, so you can use `export' et al
-  to set up variables for them.  They used to run with the environment
-  that `make' started with.
-
-Version 3.66 (21 May 1993)
-
-* `make --version' (or `make -v') now exits immediately after printing
-  the version number.
-
-Version 3.65 (09 May 1993)
-
-* Make now supports long-named members in `ar' archive files.
-
-Version 3.64 (21 Apr 1993)
-
-* Make now supports the `+=' syntax for a variable definition which appends
-  to the variable's previous value.  See the section `Appending More Text
-  to Variables' in the manual for full details.
-
-* The new option `--no-print-directory' inhibits the `-w' or
-  `--print-directory' feature.  Make turns on `--print-directory'
-  automatically if you use `-C' or `--directory', and in sub-makes; some
-  users have found this behavior undesirable.
-
-* The built-in implicit rules now support the alternative extension
-  `.txinfo' for Texinfo files, just like `.texinfo' and `.texi'.
-
-Version 3.63 (22 Jan 1993)
-
-* Make now uses a standard GNU `configure' script.  See the new file
-  INSTALL for the new (and much simpler) installation procedure.
-
-* There is now a shell script to build Make the first time, if you have no
-  other `make' program.  `build.sh' is created by `configure'; see README.
-
-* GNU Make now completely conforms to the POSIX.2 specification for `make'.
-
-* Elements of the `$^' and `$?' automatic variables that are archive
-  member references now list only the member name, as in Unix and POSIX.2.
-
-* You should no longer ever need to specify the `-w' switch, which prints
-  the current directory before and after Make runs.  The `-C' switch to
-  change directory, and recursive use of Make, now set `-w' automatically.
-
-* Multiple double-colon rules for the same target will no longer have their
-  recipes run simultaneously under -j, as this could result in the two
-  recipes trying to change the file at the same time and interfering with
-  one another.
-
-* The `SHELL' variable is now never taken from the environment.
-  Each makefile that wants a shell other than the default (/bin/sh) must
-  set SHELL itself.  SHELL is always exported to child processes.
-  This change was made for compatibility with POSIX.2.
-
-* Make now accepts long options.  There is now an informative usage message
-  that tells you what all the options are and what they do.  Try `make --help'.
-
-* There are two new directives: `export' and `unexport'.  All variables are
-  no longer automatically put into the environments of the recipe lines that
-  Make runs.  Instead, only variables specified on the command line or in
-  the environment are exported by default.  To export others, use:
-        export VARIABLE
-  or you can define variables with:
-        export VARIABLE = VALUE
-  or:
-        export VARIABLE := VALUE
-  You can use just:
-        export
-  or:
-        .EXPORT_ALL_VARIABLES:
-  to get the old behavior.  See the node `Variables/Recursion' in the manual
-  for a full description.
-
-* The recipe from the `.DEFAULT' special target is only applied to
-  targets which have no rules at all, not all targets with no recipe.
-  This change was made for compatibility with Unix make.
-
-* All fatal error messages now contain `***', so they are easy to find in
-  compilation logs.
-
-* Dependency file names like `-lNAME' are now replaced with the actual file
-  name found, as with files found by normal directory search (VPATH).
-  The library file `libNAME.a' may now be found in the current directory,
-  which is checked before VPATH; the standard set of directories (/lib,
-  /usr/lib, /usr/local/lib) is now checked last.
-  See the node `Libraries/Search' in the manual for full details.
-
-* A single `include' directive can now specify more than one makefile to
-  include, like this:
-        include file1 file2
-  You can also use shell file name patterns in an `include' directive:
-        include *.mk
-
-* The default directories to search for included makefiles, and for
-  libraries specified with `-lNAME', are now set by configuration.
-
-* You can now use blanks as well as colons to separate the directories in a
-  search path for the `vpath' directive or the `VPATH' variable.
-
-* You can now use variables and functions in the left hand side of a
-  variable assignment, as in "$(foo)bar = value".
-
-* The `MAKE' variable is always defined as `$(MAKE_COMMAND) $(MAKEOVERRIDES)'.
-  The `MAKE_COMMAND' variable is now defined to the name with which make
-  was invoked.
-
-* The built-in rules for C++ compilation now use the variables `$(CXX)' and
-  `$(CXXFLAGS)' instead of `$(C++)' and `$(C++FLAGS)'.  The old names had
-  problems with shells that cannot have `+' in environment variable names.
-
-* The value of a recursively expanded variable is now expanded when putting
-  it into the environment for child processes.  This change was made for
-  compatibility with Unix make.
-
-* A rule with no targets before the `:' is now accepted and ignored.
-  This change was made for compatibility with SunOS 4 make.
-  We do not recommend that you write your makefiles to take advantage of this.
-
-* The `-I' switch can now be used in MAKEFLAGS, and are put there
-  automatically just like other switches.
-
-Version 3.61
-
-* Built-in rules for C++ source files with the `.C' suffix.
-  We still recommend that you use `.cc' instead.
-
-* If a recipe is given too many times for a single target, the last one
-  given is used, and a warning message is printed.
-
-* Error messages about makefiles are in standard GNU error format,
-  so C-x ` in Emacs works on them.
-
-* Dependencies of pattern rules which contain no % need not actually exist
-  if they can be created (just like dependencies which do have a %).
-
-Version 3.60
-
-* A message is always printed when Make decides there is nothing to be done.
-  It used to be that no message was printed for top-level phony targets
-  (because "`phony' is up to date" isn't quite right).  Now a different
-  message "Nothing to be done for `phony'" is printed in that case.
-
-* Archives on AIX now supposedly work.
-
-* When the recipes specified for .DEFAULT are used to update a target,
-  the $< automatic variable is given the same value as $@ for that target.
-  This is how Unix make behaves, and this behavior is mandated by POSIX.2.
-
-Version 3.59
-
-* The -n, -q, and -t options are not put in the `MAKEFLAGS' and `MFLAG'
-  variables while remaking makefiles, so recursive makes done while remaking
-  makefiles will behave properly.
-
-* If the special target `.NOEXPORT' is specified in a makefile,
-  only variables that came from the environment and variables
-  defined on the command line are exported.
-
-Version 3.58
-
-* Suffix rules may have dependencies (which are ignored).
-
-Version 3.57
-
-* Dependencies of the form `-lLIB' are searched for as /usr/local/lib/libLIB.a
-  as well as libLIB.a in /usr/lib, /lib, the current directory, and VPATH.
-
-Version 3.55
-
-* There is now a Unix man page for GNU Make.  It is certainly not a
-  replacement for the Texinfo manual, but it documents the basic
-  functionality and the switches.  For full documentation, you should
-  still read the Texinfo manual.  Thanks to Dennis Morse of Stanford
-  University for contributing the initial version of this.
-
-* Variables which are defined by default (e.g., `CC') will no longer be
-  put into the environment for child processes.  (If these variables are
-  reset by the environment, makefiles, or the command line, they will
-  still go into the environment.)
-
-* Makefiles which have recipes but no dependencies (and thus are always
-  considered out of date and in need of remaking), will not be remade (if they
-  were being remade only because they were makefiles).  This means that GNU
-  Make will no longer go into an infinite loop when fed the makefiles that
-  `imake' (necessary to build X Windows) produces.
-
-* There is no longer a warning for using the `vpath' directive with an explicit
-pathname (instead of a `%' pattern).
-
-Version 3.51
-
-* When removing intermediate files, only one `rm' command line is printed,
-  listing all file names.
-
-* There are now automatic variables `$(^D)', `$(^F)', `$(?D)', and `$(?F)'.
-  These are the directory-only and file-only versions of `$^' and `$?'.
-
-* Library dependencies given as `-lNAME' will use "libNAME.a" in the current
-  directory if it exists.
-
-* The automatic variable `$($/)' is no longer defined.
-
-* Leading `+' characters on a recipe line make that line be executed even
-  under -n, -t, or -q (as if the line contained `$(MAKE)').
-
-* For recipe lines containing `$(MAKE)', `${MAKE}', or leading `+' characters,
-  only those lines are executed, not the entire recipe.
-  (This is how Unix make behaves for lines containing `$(MAKE)' or `${MAKE}'.)
-
-Version 3.50
-
-* Filenames in rules will now have ~ and ~USER expanded.
-
-* The `-p' output has been changed so it can be used as a makefile.
-  (All information that isn't specified by makefiles is prefaced with comment
-  characters.)
-
-Version 3.49
-
-* The % character can be quoted with backslash in implicit pattern rules,
-  static pattern rules, `vpath' directives, and `patsubst', `filter', and
-  `filter-out' functions.  A warning is issued if a `vpath' directive's
-  pattern contains no %.
-
-* The `wildcard' variable expansion function now expands ~ and ~USER.
-
-* Messages indicating failed recipe lines now contain the target name:
-        make: *** [target] Error 1
-
-* The `-p' output format has been changed somewhat to look more like
-  makefile rules and to give all information that Make has about files.
-
-Version 3.48
-
-Version 3.47
-
-* The `-l' switch with no argument removes any previous load-average limit.
-
-* When the `-w' switch is in effect, and Make has updated makefiles,
-  it will write a `Leaving directory' message before re-executing itself.
-  This makes the `directory change tracking' changes to Emacs's compilation
-  commands work properly.
-
-Version 3.46
-
-* The automatic variable `$*' is now defined for explicit rules,
-  as it is in Unix make.
-
-Version 3.45
-
-* The `-j' switch is now put in the MAKEFLAGS and MFLAGS variables when
-  specified without an argument (indicating infinite jobs).
-  The `-l' switch is not always put in the MAKEFLAGS and MFLAGS variables.
-
-* Make no longer checks hashed directories after running recipes.
-  The behavior implemented in 3.41 caused too much slowdown.
-
-Version 3.44
-
-* A dependency is NOT considered newer than its dependent if
-  they have the same modification time.  The behavior implemented
-  in 3.43 conflicts with RCS.
-
-Version 3.43
-
-* Dependency loops are no longer fatal errors.
-
-* A dependency is considered newer than its dependent if
-  they have the same modification time.
-
-Version 3.42
-
-* The variables F77 and F77FLAGS are now set by default to $(FC) and
-  $(FFLAGS).  Makefiles designed for System V make may use these variables in
-  explicit rules and expect them to be set.  Unfortunately, there is no way to
-  make setting these affect the Fortran implicit rules unless FC and FFLAGS
-  are not used (and these are used by BSD make).
-
-Version 3.41
-
-* Make now checks to see if its hashed directories are changed by recipes.
-  Other makes that hash directories (Sun, 4.3 BSD) don't do this.
-
-Version 3.39
-
-* The `shell' function no longer captures standard error output.
-
-Version 3.32
-
-* A file beginning with a dot can be the default target if it also contains
-  a slash (e.g., `../bin/foo').  (Unix make allows this as well.)
-
-Version 3.31
-
-* Archive member names are truncated to 15 characters.
-
-* Yet more USG stuff.
-
-* Minimal support for Microport System V (a 16-bit machine and a
-  brain-damaged compiler).  This has even lower priority than other USG
-  support, so if it gets beyond trivial, I will take it out completely.
-
-* Revamped default implicit rules (not much visible change).
-
-* The -d and -p options can come from the environment.
-
-Version 3.30
-
-* Improved support for USG and HPUX (hopefully).
-
-* A variable reference like `$(foo:a=b)', if `a' contains a `%', is
-  equivalent to `$(patsubst a,b,$(foo))'.
-
-* Defining .DEFAULT with no deps or recipe clears its recipe.
-
-* New default implicit rules for .S (cpp, then as), and .sh (copy and
-  make executable).  All default implicit rules that use cpp (even
-  indirectly), use $(CPPFLAGS).
-
-Version 3.29
-
-* Giving the -j option with no arguments gives you infinite jobs.
-
-Version 3.28
-
-* New option: "-l LOAD" says not to start any new jobs while others are
-  running if the load average is not below LOAD (a floating-point number).
-
-* There is support in place for implementations of remote command execution
-  in Make.  See the file remote.c.
-
-Version 3.26
-
-* No more than 10 directories will be kept open at once.
-  (This number can be changed by redefining MAX_OPEN_DIRECTORIES in dir.c.)
-
-Version 3.25
-
-* Archive files will have their modification times recorded before doing
-  anything that might change their modification times by updating an archive
-  member.
-
-Version 3.20
-
-* The `MAKELEVEL' variable is defined for use by makefiles.
-
-Version 3.19
-
-* The recursion level indications in error messages are much shorter than
-  they were in version 3.14.
-
-Version 3.18
-
-* Leading spaces before directives are ignored (as documented).
-
-* Included makefiles can determine the default goal target.
-  (System V Make does it this way, so we are being compatible).
-
-Version 3.14.
-
-* Variables that are defaults built into Make will not be put in the
-  environment for children.  This just saves some environment space and,
-  except under -e, will be transparent to sub-makes.
-
-* Error messages from sub-makes will indicate the level of recursion.
-
-* Hopefully some speed-up for large directories due to a change in the
-  directory hashing scheme.
-
-* One child will always get a standard input that is usable.
-
-* Default makefiles that don't exist will be remade and read in.
-
-Version 3.13.
-
-* Count parentheses inside expansion function calls so you can
-  have nested calls: `$(sort $(foreach x,a b,$(x)))'.
-
-Version 3.12.
-
-* Several bug fixes, including USG and Sun386i support.
-
-* `shell' function to expand shell commands a la `
-
-* If the `-d' flag is given, version information will be printed.
-
-* The `-c' option has been renamed to `-C' for compatibility with tar.
-
-* The `-p' option no longer inhibits other normal operation.
-
-* Makefiles will be updated and re-read if necessary.
-
-* Can now run several recipes at once (parallelism), -j option.
-
-* Error messages will contain the level of Make recursion, if any.
-
-* The `MAKEFLAGS' and `MFLAGS' variables will be scanned for options after
-  makefiles are read.
-
-* A double-colon rule with no dependencies will always have its recipe run.
-  (This is how both the BSD and System V versions of Make do it.)
-
-Version 3.05

-(Changes from versions 1 through 3.05 were never recorded.  Sorry.)

-Short: Port of GNU make with SAS/C (no ixemul.library required)
-Author: GNU, Amiga port by Aaron "Optimizer" Digulla
-Uploader: Aaron "Optimizer" Digulla (digulla@fh-konstanz.de)
-Type: dev/c
-
-This is a pure Amiga port of GNU make. It needs no extra libraries or
-anything. It has the following features (in addition to any features of
-GNU make):
-
-- Runs Amiga-Commands with SystemTags() (Execute)
-- Can run multi-line statements
-- Allows to use Device-Names in targets:
-
-        c:make : make.o
-
-    is ok. To distinguish between device-names and target : or ::, MAKE
-    looks for spaces. If there are any around :, it's taken as a target
-    delimiter, if there are none, it's taken as the name of a device. Note
-    that "make:make.o" tries to create "make.o" on the device "make:".
-- Replaces @@ by a newline in any command line:
-
-        if exists make @@\
-            delete make.bak quiet @@\
-            rename make make.bak @@\
-        endif @@\
-        $(CC) Link Make.o To make
-
-    works. Note that the @@ must stand alone (i.e., "make@@\" is illegal).
-    Also be careful that there is a space after the "\" (i.e., at the
-    beginning of the next line).
-- Can be made resident to save space and time
-- Amiga specific wildcards can be used in $(wildcard ...)
-
-BUGS:
-- The line
-
-    dummy.h : src/*.c
-
-tries to make dummy.h from "src/*.c" (i.e., no wildcard-expansion takes
-place). You have to use "$(wildcard src/*.c)" instead.
-
-COMPILING FROM SCRATCH
-----------------------
-
-To recompile, you need SAS/C 6.51.
-
-As of GNU make 4.3, the build environment has been cleaned up and alternate
-make files (including smakefiles) have been removed.  If you have an existing
-version of GNU make available you _should_ be able to run:
-
-   make -f Basic.mk
-
-However this is untested.
-
-If you have an Amiga system and would like to collaborate on getting
-bootstrapping to work properly please contact bug-make@gnu.org.
-
-INSTALLATION
-
-Copy make somewhere in your search path (e.g., sc:c or sc:bin).
-If you plan to use recursive makes, install make resident:
-
-    Resident make Add

-Port of GNU Make to 32-bit protected mode on MSDOS and MS-Windows.
-
-Builds with DJGPP v2 port of GNU C/C++ compiler and utilities.
-
-
-New (since 3.74) DOS-specific features:
-
-   1. Supports long filenames when run from DOS box on Windows 9x.
-
-   2. Supports both stock DOS COMMAND.COM and Unix-style shells
-      (details in 'Notes' below).
-
-   3. Supports DOS drive letters in dependencies and pattern rules.
-
-   4. Better support for DOS-style backslashes in pathnames (but see
-      'Notes' below).
-
-   5. The $(shell) built-in can run arbitrary complex commands,
-      including pipes and redirection, even when COMMAND.COM is your
-      shell.
-
-   6. Can be built without floating-point code (see below).
-
-   7. Supports signals in child programs and restores the original
-      directory if the child was interrupted.
-
-   8. Can be built without (a previous version of) Make.
-
-   9. The build process requires only standard tools.  (Optional
-      targets like "check:" still need additional programs, though,
-      see below.)
-
-  10. Beginning with v3.78, the test suite works in the DJGPP
-      environment (requires Perl and auxiliary tools; see below).
-
-
-To install a binary distribution:
-
-   Simply unzip the makNNNb.zip file (where NNN is the version number)
-   preserving the directory structure (-d switch if you use PKUNZIP).
-   If you are installing Make on Windows 9X or Windows 2000, use an
-   unzip program that supports long filenames in zip files.  After
-   unzipping, make sure the directory with make.exe is on your PATH,
-   and that's all you need to use Make.
-
-
-To build from sources:
-
-   1. Unzip the archive, preserving the directory structure (-d switch
-      if you use PKUNZIP).  If you build Make on Windows 9X or Windows
-      2000, use an unzip program that supports long filenames in zip
-      files.
-
-      If you are unpacking an official GNU source distribution, use
-      either DJTAR (which is part of the DJGPP development
-      environment), or the DJGPP port of GNU Tar.
-
-   2. If you have a working Make already, you can run:
-
-          make -f Basic.mk
-
-   3. If you don't have a working Make already you can bootstrap one
-      by running:
-
-          .\builddos.bat
-
-   4. If you are building from outside of the source directory, you
-      need to tell Make where the sources are, like this:
-
-          make -f c:/djgpp/gnu/make/Basic.mk SRCDIR=c:/djgpp/gnu/make
-
-      or:
-
-          c:/djgpp/gnu/make/builddos.bat c:/djgpp/gnu/make
-
-   5. To run the test suite, type "make check".  This requires a Unix
-      shell (I used the DJGPP port of Bash 2.03), Perl, Sed, Fileutils
-      and Sh-utils.
-
-   6. To install copy make.exe to the preferred location.
-
-      Since GNU make 4.3, support for customized platform installations
-      has been removed.  If you'd like to collaborate on reinstating
-      these capabilities, contact bug-make@gnu.org.
-
-
-Notes:
------
-
-   1. The shell issue.
-
-      This is probably the most significant improvement, first
-      introduced in the port of GNU Make 3.75.
-
-      The original behavior of GNU Make is to invoke commands
-      directly, as long as they don't include characters special to
-      the shell or internal shell commands, because that is faster.
-      When shell features like redirection or filename wildcards are
-      involved, Make calls the shell.
-
-      This port supports both DOS shells (the stock COMMAND.COM and its
-      4DOS/NDOS replacements), and Unix-style shells (tested with the
-      venerable Stewartson's 'ms_sh' 2.3 and the DJGPP port of 'bash' by
-      Daisuke Aoyama <jack@st.rim.or.jp>).
-
-      When the $SHELL variable points to a Unix-style shell, Make
-      works just like you'd expect on Unix, calling the shell for any
-      command that involves characters special to the shell or
-      internal shell commands.  The only difference is that, since
-      there is no standard way to pass command lines longer than the
-      infamous DOS 126-character limit, this port of Make writes the
-      command line to a temporary disk file and then invokes the shell
-      on that file.
-
-      If $SHELL points to a DOS-style shell, however, Make will not
-      call it automatically, as it does with Unix shells.  Stock
-      COMMAND.COM is too dumb and would unnecessarily limit the
-      functionality of Make.  For example, you would not be able to
-      use long command lines in commands that use redirection or
-      pipes.  Therefore, when presented with a DOS shell, this port of
-      Make will emulate most of the shell functionality, like
-      redirection and pipes, and shall only call the shell when a
-      batch file or a command internal to the shell is invoked.  (Even
-      when a command is an internal shell command, Make will first
-      search the $PATH for it, so that if a Makefile calls 'mkdir',
-      you can install, say, a port of GNU 'mkdir' and have it called
-      in that case.)
-
-      The key to all this is the extended functionality of 'spawn' and
-      'system' functions from the DJGPP library; this port just calls
-      'system' where it would invoke the shell on Unix.  The most
-      important aspect of these functions is that they use a special
-      mechanism to pass long (up to 16KB) command lines to DJGPP
-      programs.  In addition, 'system' emulates some internal
-      commands, like 'cd' (so that you can now use forward slashes
-      with it, and can also change the drive if the directory is on
-      another drive).  Another aspect worth mentioning is that you can
-      call Unix shell scripts directly, provided that the shell whose
-      name is mentioned on the first line of the script is installed
-      anywhere along the $PATH.  It is impossible to tell here
-      everything about these functions; refer to the DJGPP library
-      reference for more details.
-
-      The $(shell) built-in is implemented in this port by calling
-      'popen'.  Since 'popen' calls 'system', the above considerations
-      are valid for $(shell) as well.  In particular, you can put
-      arbitrary complex commands, including pipes and redirection,
-      inside $(shell), which is in many cases a valid substitute for
-      the Unix-style command substitution (`command`) feature.
-
-
-   2. "SHELL=/bin/sh" -- or is it?
-
-      Many Unix Makefiles include a line which sets the SHELL, for
-      those versions of Make which don't have this as the default.
-      Since many DOS systems don't have 'sh' installed (in fact, most
-      of them don't even have a '/bin' directory), this port takes
-      such directives with a grain of salt.  It will only honor such a
-      directive if the basename of the shell name (like 'sh' in the
-      above example) can indeed be found in the directory that is
-      mentioned in the SHELL= line ('/bin' in the above example), or
-      in the current working directory, or anywhere on the $PATH (in
-      that order).  If the basename doesn't include a filename
-      extension, Make will look for any known extension that indicates
-      an executable file (.exe, .com, .bat, .btm, .sh, and even .sed
-      and .pl).  If any such file is found, then $SHELL will be
-      defined to the exact pathname of that file, and that shell will
-      hence be used for the rest of processing.  But if the named
-      shell is *not* found, the line which sets it will be effectively
-      ignored, leaving the value of $SHELL as it was before.  Since a
-      lot of decisions that this port makes depend on the gender of
-      the shell, I feel it doesn't make any sense to tailor Make's
-      behavior to a shell which is nowhere to be found.
-
-      Note that the above special handling of "SHELL=" only happens
-      for Makefiles; if you set $SHELL in the environment or on the
-      Make command line, you are expected to give the complete
-      pathname of the shell, including the filename extension.
-
-      The default value of $SHELL is computed as on Unix (see the Make
-      manual for details), except that if $SHELL is not defined in the
-      environment, $COMSPEC is used.  Also, if an environment variable
-      named $MAKESHELL is defined, it takes precedence over both
-      $COMSPEC and $SHELL.  Note that, unlike Unix, $SHELL in the
-      environment *is* used to set the shell (since on MSDOS, it's
-      unlikely that the interactive shell will not be suitable for
-      Makefile processing).
-
-      The bottom line is that you can now write Makefiles where some
-      of the targets require a real (i.e. Unix-like) shell, which will
-      nevertheless work when such shell is not available (provided, of
-      course, that the commands which should always work, don't
-      require such a shell).  More important, you can convert Unix
-      Makefiles to MSDOS and leave the line which sets the shell
-      intact, so that people who do have Unixy shell could use it for
-      targets which aren't converted to DOS (like 'install' and
-      'uninstall', for example).
-
-
-   3. Default directories.
-
-      GNU Make knows about standard directories where it searches for
-      library and include files mentioned in the Makefile.  Since
-      MSDOS machines don't have standard places for these, this port
-      will search ${DJDIR}/lib and ${DJDIR}/include respectively.
-      $DJDIR is defined automatically by the DJGPP startup code as the
-      root of the DJGPP installation tree (unless you've tampered with
-      the DJGPP.ENV file).  This should provide reasonable default
-      values, unless you moved parts of DJGPP to other directories.
-
-
-   4. Letter-case in filenames.
-
-      If you run Make on Windows 9x, you should be aware of the
-      letter-case issue.  Make is internally case-sensitive, but all
-      file operations are case-insensitive on Windows 9x, so
-      e.g. files 'FAQ', 'faq' and 'Faq' all refer to the same file, as
-      far as Windows is concerned.  The underlying DJGPP C library
-      functions honor the letter-case of the filenames they get from
-      the OS, except that by default, they down-case 8+3 DOS filenames
-      which are stored in upper case in the directory and would break
-      many Makefiles otherwise.  (The details of which filenames are
-      converted to lower case are explained in the DJGPP libc docs,
-      under the '_preserve_fncase' and '_lfn_gen_short_fname'
-      functions, but as a thumb rule, any filename that is stored in
-      upper case in the directory, is a valid DOS 8+3 filename and
-      doesn't include characters invalid on MSDOS FAT filesystems,
-      will be automatically down-cased.)  User reports that I have
-      indicate that this default behavior is generally what you'd
-      expect; however, your input is most welcome.
-
-      In any case, if you hit a situation where you must force Make to
-      get the 8+3 DOS filenames in upper case, set FNCASE=y in the
-      environment or in the Makefile.
-
-
-   5. DOS-style pathnames.
-
-      There are a lot of places throughout the program sources which
-      make implicit assumptions about the pathname syntax.  In
-      particular, the directories are assumed to be separated by '/',
-      and any pathname which doesn't begin with a '/' is assumed to be
-      relative to the current directory.  This port attempts to
-      support DOS-style pathnames which might include the drive letter
-      and use backslashes instead of forward slashes.  However, this
-      support is not complete; I feel that pursuing this support too
-      far might break some more important features, particularly if
-      you use a Unix-style shell (where a backslash is a quote
-      character).  I only consider support of backslashes desirable
-      because some Makefiles invoke non-DJGPP programs which don't
-      understand forward slashes.  A notable example of such programs
-      is the standard programs which come with MSDOS.  Otherwise, you
-      are advised to stay away from backslashes whenever possible.  In
-      particular, filename globbing won't work on pathnames with
-      backslashes, because the GNU 'glob' library doesn't support them
-      (backslash is special in filename wildcards, and I didn't want
-      to break that).
-
-      One feature which *does* work with backslashes is the filename-
-      related built-in functions such as $(dir), $(notdir), etc.
-      Drive letters in pathnames are also fully supported.
-
-
-
-Bug reports:
------------
-
-   Bugs that are clearly related to the MSDOS/DJGPP port should be
-   reported first on the comp.os.msdos.djgpp news group (if you cannot
-   post to Usenet groups, write to the DJGPP mailing list,
-   <djgpp@delorie.com>, which is an email gateway into the above news
-   group).  For other bugs, please follow the procedure explained in
-   the "Bugs" chapter of the Info docs.  If you don't have an Info
-   reader, look up that chapter in the 'make.i1' file with any text
-   browser/editor.
-
-
-   Enjoy,

-Port of GNU make to OS/2.
-
-Features of GNU make that do not work under OS/2:
-  - remote job execution
-  - dynamic load balancing
-
-
-Special features of the OS/2 version:
-
-Due to the fact that some people might want to use sh syntax in
-Makefiles while others might want to use OS/2's native shell cmd.exe,
-GNU make supports both shell types. The following list defines the order
-that is used to determine the shell:
-
- 1. The shell specified by the environment variable MAKESHELL.
- 2. The shell specified by the SHELL variable within a Makefile. Like
-    Unix, SHELL is NOT taken from the environment.
- 3. The shell specified by the COMSPEC environment variable.
- 4. The shell specified by the OS2_SHELL environment variable.
- 5. If none of the above is defined /bin/sh is used as default.  This
-    happens e.g. in the make testsuite.
-
-Note: - Points 3 and 4 can be turned off at compile time by adding
-        -DNO_CMD_DEFAULT to the CPPFLAGS.
-      - DOS support is not tested for EMX and therefore might not work.
-      - The UNIXROOT environment variable is supported to find /bin/sh
-        if it is not on the current drive.
-
-
-COMPILATION OF GNU MAKE FOR OS/2:
-
-I. ***** SPECIAL OPTIONS *****
-
- - At compile time you can turn off that cmd is used as default shell
-   (but only /bin/sh). Simply set CPPFLAGS="-DNO_CMD_DEFAULT" and make
-   will not use cmd unless you cause it to do so by setting MAKESHELL to
-   cmd or by specifying SHELL=cmd in your Makefile.
-
- - At compile time you can set CPPFLAGS="-DNO_CHDIR2" to turn off that
-   GNU make prints drive letters. This is necessary if you want to run
-   the testsuite.
-
-
-II. ***** REQUIREMENTS FOR THE COMPILATION *****
-
-A standard Unix like build environment:
-
- - sh compatible shell (ksh, bash, ash, but tested only with pdksh 5.2.14
-   release 2)
-   If you use pdksh it is recommended to update to 5.2.14 release 2. Older
-   versions may not work! You can get this version at
-   http://www.math.ohio-state.edu/~ilya/software/os2/pdksh-5.2.14-bin-2.zip
- - GNU file utilities (make sure that install.exe from the file utilities
-   is in front of your PATH before X:\OS2\INSTALL\INSTALL.EXE. I recommend
-   also to change the filename to ginstall.exe instead of install.exe
-   to avoid confusion with X:\OS2\INSTALL\INSTALL.EXE)
- - GNU shell utilities
- - GNU text utilities
- - gawk
- - grep
- - sed
- - GNU make 3.79.1 (special OS/2 patched version) or higher
- - perl 5.005 or higher
- - GNU texinfo (you can use 3.1 (gnuinfo.zip), but I recommend 4.0)
-
-If you want to recreate the configuration files (developers only!)
-you need also: GNU m4 1.4, autoconf 2.59, automake 1.9.6 (or compatible)
-
-
-III. ***** COMPILATION AND INSTALLATION *****
-
- a) ** Developers only - Everyone else should skip this section **
-    To recreate the configuration files use:
-
-      export EMXSHELL=ksh
-      aclocal -I config
-      automake
-      autoconf
-      autoheader
-
-
-b) Installation into x:/usr
-
-   Note: Although it is possible to compile make using "./configure",
-         "make", "make install" this is not recommended.  In particular,
-         you must ALWAYS use LDFLAGS="-Zstack 0x6000" because the default
-         stack size is far to small and make will not work properly!
-
-Recommended environment variables and installation options:
-
-    export ac_executable_extensions=".exe"
-    export CPPFLAGS="-D__ST_MT_ERRNO__"
-    export CFLAGS="-O2 -Zomf -Zmt"
-    export LDFLAGS="-Zcrtdll -Zlinker /exepack:2 -Zlinker /pm:vio -Zstack 0x6000"
-    export RANLIB="echo"
-    ./configure --prefix=x:/usr --infodir=x:/usr/share/info --mandir=x:/usr/share/man --without-included-gettext
-    make AR=emxomfar
-    make install
-
-Note: If you use gcc 2.9.x I recommend to set also LIBS="-lgcc"
-
-Note: You can add -DNO_CMD_DEFAULT and -DNO_CHDIR2 to CPPFLAGS.
-      See section I. for details.
-
-
-IV. ***** NLS support *****
-
-GNU make has NLS (National Language Support), with the following
-caveats:
-
- a) It will only work with GNU gettext, and
- b) GNU gettext support is not included in the GNU make package.
-
-Therefore, if you wish to enable the internationalization features of
-GNU make you must install GNU gettext on your system before configuring
-GNU make.
-
-You can choose the languages to be installed. To install support for
-English, German and French only enter:
-
-  export LINGUAS="en de fr"
-
-If you don't specify LINGUAS all languages are installed.
-
-If you don't want NLS support (English only) use the option
---disable-nls for the configure script.  Note if GNU gettext is not
-installed then NLS will not be enabled regardless of this flag.
-
-
-V. ***** Running the make test suite *****
-
-To run the included make test suite you have to set
-
-  CPPFLAGS="-D__ST_MT_ERRNO__ -DNO_CMD_DEFAULT -DNO_CHDIR2"
-
-before you compile make. This is due to some restrictions of the
-testsuite itself. -DNO_CMD_DEFAULT causes make to use /bin/sh as default
-shell in every case. Normally you could simply set MAKESHELL="/bin/sh"
-to do this but the testsuite ignores the environment. -DNO_CHDIR2 causes
-make not to use drive letters for directory names (i.e. _chdir2() and
-_getcwd2() are NOT used).  The testsuite interpretes the whole output of
-make, especially statements like make[1]: Entering directory
-'C:/somewhere/make-3.79.1/tests' where the testsuite does not expect the
-drive letter. This would be interpreted as an error even if there is
-none.
-
-To run the testsuite do the following:
-
-  export CPPFLAGS="-D__ST_MT_ERRNO__ -DNO_CMD_DEFAULT -DNO_CHDIR2"
-  export CFLAGS="-Zomf -O2 -Zmt"
-  export LDFLAGS="-Zcrtdll -s -Zlinker /exepack:2 -Zlinker /pm:vio -Zstack 0x6000"
-  export RANLIB="echo"
-  ./configure --prefix=x:/usr --disable-nls
-  make AR=emxomfar
-  make check
-
-All tests should work fine with the exception of one of the "INCLUDE_DIRS"
-tests which will fail if your /usr/include directory is on a drive different
-from the make source tree.

----------
-
-  This version of GNU make has been tested on:
-  OpenVMS V8.3/V8.4 (Alpha) and V8.4 (Integrity) AND V7.3 (VAX)
-
-  This version of GNU Make is intended to be run from DCL to run
-  make scripts with a special syntax that is described below.  It
-  likely will not be able to run unmodified Unix makefiles.
-
-  There is an older implementation of GNU Make that was ported to GNV.
-  Work is now in progress to merge that port to get a single version
-  of GNU Make available.  When that merge is done, GNU Make will auto
-  detect that it is running under a Posix shell and then operate as close to
-  GNU Make on Unix as possible.
-
-  The descriptions below are for running GNU make from DCL or equivalent.
-
-Recipe differences:
--------------------
-
-  GNU Make for OpenVMS can not currently run native Unix make files because of
-  differences in the implementation.
-
-  I am trying to document the current behavior in this section.  This is based
-  on the information in the file NEWS. and running the test suite.
-  TODO: More tests are needed to validate and demonstrate the OpenVMS
-  expected behavior.
-
-  In some cases the older behavior of GNU Make when run from DCL is not
-  compatible with standard makefile behavior.
-
-  This behavior can be changed when running GNU Make from DCL by setting
-  either DCL symbols or logical names of the format GNV$.  The settings
-  are enabled with a string starting with one of '1', 'T', or 'E' for "1",
-  "TRUE", or "ENABLE".  They are disabled with a '0', 'F', or 'D' for "1",
-  "FALSE", or "DISABLE".  If they are not explicitly set to one of these
-  values, then they will be set to their default values.
-
-  The value of the setting DECC$FILENAME_UNIX_REPORT or
-  DECC$FILENAME_UNIX_ONLY will now cause the $(dir x) function to return
-  './' or '[]' as appropriate.
-
-  The name GNV$MAKE_OLD_VMS when enabled will cause GNU Make to behave as
-  much as the older method as can be done with out disabling VMS features.
-  When it is disabled GNU Make have the new behavior which more closely
-  matches Unix Make behavior.
-
-  The default is currently the old behavior when running GNU Make from DCL.
-  In the future this may change.  When running make from GNV Bash the new
-  behavior is the default.
-
-  This is a global setting that sets the default behavior for several other
-  options that can be individually changed.  Many of the individual settings
-  are to make it so that the self tests for GNU Make need less VMS specific
-  modifications.
-
-  The name GNV$MAKE_COMMA when enabled will cause GNU Make to expect a comma
-  for a path separator and use a comma for the separator for a list of files.
-  When disabled, it will cause GNU Make to use a colon for a path separator
-  and a space for the separator for a list of files.  The default is to be
-  enabled if the GNU Make is set to the older behavior.
-
-  The name GNV$MAKE_SHELL_SIM when enabled will cause GNU Make to try to
-  simulate a Posix shell more closely.  The following behaviors occur:
-
-    * Single quotes are converted to double quotes and any double
-      quotes inside of them are doubled.  No environment variable expansion
-      is simulated.
-    * A exit command status will be converted to a Posix Exit
-      where 0 is success and non-zero is failure.
-    * The $ character will cause environment variable expansion.
-    * Environent variables can be set on the command line before a command.
-
-  VMS generally uses logical name search lists instead of path variables
-  where the resolution is handled by VMS independent of the program.  Which
-  means that it is likely that nothing will notice if the default path
-  specifier is changed in the future.
-
-  Currently the built in VMS specific macros and recipes depend on the comma
-  being used as a file list separator.
-  TODO: Remove this dependency as other functions in GNU Make depend on a
-  space being used as a separator.
-
-  The format for recipes are a combination of Unix macros, a subset of
-  simulated UNIX commands, some shell emulation, and OpenVMS commands.
-  This makes the resulting makefiles unique to the OpenVMS port of GNU make.
-
-  If you are creating a OpenVMS specific makefile from scratch, you should also
-  look at MMK (Madgoat Make) available at https://github.com/endlesssoftware/mmk
-  MMK uses full OpenVMS syntax and a persistent subprocess is used for the
-  recipe lines, allowing multiple line rules.
-
-  The default makefile search order is "makefile.vms", "gnumakefile",
-  "makefile".  TODO: See if that lookup is case sensitive.
-
-  When Make is invoked from DCL, it will create a foreign command
-  using the name of executable image, with any facility prefix removed,
-  for the duration of the make program, so it can be used internally
-  to recursively run make().  The macro MAKE_COMMAND will be set to
-  this foreign command.
-
-  When make is launched from an exec*() command from a C program,
-  the foreign command is not created.  The macro MAKE_COMMAND will be
-  set to the actual command passed as argv[0] to the exec*() function.
-
-  If the DCL symbol or logical name GNV$MAKE_USE_MCR exists, then
-  the macro MAKE_COMMAND will be set to be an "MCR" command with the
-  absolute path used by DCL to launch make.  The foreign command
-  will not be created.
-
-  The macro MAKE is set to be the same value as the macro MAKE_COMMAND
-  on all platforms.
-
-  Each recipe command is normally run as a separate spawned processes,
-  except for the cases documented below where a temporary DCL command
-  file may be used.
-
-  BUG: Testing has shown that the commands in the temporary command files
-  are not always created properly.  This issue is still under investigation.
-
-  Any macros marked as exported are temporarily created as DCL symbols
-  for child images to use.  DCL symbol substitution is not done with these
-  commands.
-  Untested: Symbol substitution.
-
-  When a temporary DCL command file is used, DCL symbol substitution
-  will work.
-
-  For VMS 7.3-1 and earlier, command lines are limited to 255 characters
-  or 1024 characters in a command file.
-  For VMS 7.3-2 and later, command lines are limited to 4059 characters
-  or 8192 characters in a command file.
-
-  VMS limits each token of a command line to 256 characters, and limits
-  a command line to 127 tokens.
-
-  Command lines above the limit length are written to a command file
-  in sys$scratch:.
-
-  In order to handle Unix style extensions to VMS DCL, GNU Make has
-  parsed the recipe commands and them modified them as needed.  The
-  parser has been re-written to resolve numerous bugs in handling
-  valid VMS syntax and potential buffer overruns.
-
-  The new parser may need whitespace characters where DCL does not require
-  it, and also may require that quotes are matched were DCL forgives if
-  they are not.  There is a small chance that existing VMS specific makefiles
-  will be affected.
-
-  The '<', '>' was previously implemented using command files.  Now
-  GNU Make will check to see if the is already a VMS "PIPE" command and
-  if it is not, will convert the command to a VMS "PIPE" command.
-
-  The '>>' redirection has been implemented by using a temporary command file.
-  This will be described later.
-
-  The DCL symbol or logical name GNV$MAKE_USE_CMD_FILE when set to a
-  string starting with one of '1','T', or 'E' for "1", "TRUE", or "ENABLE",
-  then temporary DCL command files are always used for running commands.
-
-  Some recipe strings with embedded new lines will not be handled correctly
-  when a command file is used.
-
-  GNU Make generally does text comparisons for the targets and sources.  The
-  make program itself can handle either Unix or OpenVMS format filenames, but
-  normally does not do any conversions from one format to another.
-  TODO: The OpenVMS format syntax handling is incomplete.
-  TODO: ODS-5 EFS support is missing.
-  BUG: The internal routines to convert filenames to and from OpenVMS format
-  do not work correctly.
-
-  Note: In the examples below, line continuations such as a backslash may have
-  been added to make the examples easier to read in this format.
-  BUG: That feature does not completely work at this time.
-
-  Since the OpenVMS utilities generally expect OpenVMS format paths, you will
-  usually have to use OpenVMS format paths for rules and targets.
-  BUG: Relative OpenVMS paths may not work in targets, especially combined
-  with vpaths.  This is because GNU make will just concatenate the directories
-  as it does on Unix.
-
-  The variables $^ and $@ separate files with commas instead of spaces.
-  This is controlled by the name GNV$MAKE_COMMA as documented in the
-  previous section.
-
-  While this may seem the natural thing to do with OpenVMS, it actually
-  causes problems when trying to use other make functions that expect the
-  files to be separated by spaces.  If you run into this, you need the
-  following workaround to convert the output.
-  TODO: Look at have the $^ and $@ use spaces like on Unix and have
-  and easy to use function to do the conversions and have the built
-  in OpenVMS specific recipes and macros use it.
-
-  Example:
-
-comma := ,
-empty :=
-space := $(empty) $(empty)
-
-foo: $(addsuffix .3,$(subs $(comma),$(space),$^)
-
-
-  Makefile variables are looked up in the current environment. You can set
-  symbols or logicals in DCL and evaluate them in the Makefile via
-  $(<name-of-symbol-or-logical>).  Variables defined in the Makefile
-  override OpenVMS symbols/logicals.
-
-  OpenVMS logical and symbols names show up as "environment" using the
-  origin function.  when the "-e" option is specified, the origion function
-  shows them as "environment override".  On Posix the test scripts indicate
-  that they should show up just as "environment".
-
-  When GNU make reads in a symbol or logical name into the environment, it
-  converts any dollar signs found to double dollar signs for convenience in
-  using DCL symbols and logical names in recipes.  When GNU make exports a
-  DCL symbol for a child process, if the first dollar sign found is followed
-  by second dollar sign, then all double dollar signs will be convirted to
-  single dollar signs.
-
-  The variable $(ARCH) is predefined as IA64, ALPHA or VAX respectively.
-  Makefiles for different OpenVMS systems can now be written by checking
-  $(ARCH).  Since IA64 and ALPHA are similar, usually just a check for
-  VAX or not VAX is sufficient.
-
-  You may have to update makefiles that assume VAX if not ALPHA.
-
-ifeq ($(ARCH),VAX)
-  $(ECHO) "On the VAX"
-else
-  $(ECHO) "On the ALPHA  or IA64"
-endif
-
-  Empty commands are handled correctly and don't end in a new DCL process.
-
-  The exit command needs to have OpenVMS exit codes.  To pass a Posix code
-  back to the make script, you need to encode it by multiplying it by 8
-  and then adding %x1035a002 for a failure code and %x1035a001 for a
-  success.  Make will interpret any posix code other than 0 as a failure.
-  TODO: Add an option have simulate Posix exit commands in recipes.
-
-  Lexical functions can be used in pipes to simulate shell file test rules.
-
-  Example:
-
-  Posix:
-b : c ; [ -f $@ ] || echo >> $@
-
-  OpenVMS:
-b : c ; if f$$search("$@") then pipe open/append xx $@ ; write xx "" ; close xx
-
-
-  You can also use pipes and turning messages off to silently test for a
-  failure.
-
-x = %x1035a00a
-
-%.b : %.c
-<tab>pipe set mess/nofac/noiden/nosev/notext ; type $^/output=$@ || exit $(x)
-
-
-Runtime issues:
-
-  The OpenVMS C Runtime has a convention for encoding a Posix exit status into
-  to OpenVMS exit codes.  These status codes will have the hex value of
-  0x35a000.  OpenVMS exit code may also have a hex value of %x10000000 set on
-  them.  This is a flag to tell DCL not to write out the exit code.
-
-  To convert an OpenVMS encoded Posix exit status code to the original code
-  You subtract %x35a000 and any flags from the OpenVMS code and divide it by 8.
-
-  WARNING: Backward-incompatibility!
-  The make program exit now returns the same encoded Posix exit code as on
-  Unix. Previous versions returned the OpenVMS exit status code if that is what
-  caused the recipe to fail.
-  TODO: Provide a way for scripts calling make to obtain that OpenVMS status
-  code.
-
-  Make internally has two error codes, MAKE_FAILURE and MAKE_TROUBLE.  These
-  will have the error "-E-" severity set on exit.
-
-  MAKE_TROUBLE is returned only if the option "-q" or "--question" is used and
-  has a Posix value of 1 and an OpenVMS status of %x1035a00a.
-
-  MAKE_FAILURE has a Posix value of 2 and an OpenVMS status of %x1035a012.
-
-  Output from GNU make may have single quotes around some values where on
-  other platforms it does not.  Also output that would be in double quotes
-  on some platforms may show up as single quotes on VMS.
-
-  There may be extra blank lines in the output on VMS.
-  https://savannah.gnu.org/bugs/?func=detailitem&item_id=41760
-
-  There may be a "Waiting for unfinished jobs..." show up in the output.
-
-  Error messages generated by Make or Unix utilities may slightly vary from
-  Posix platforms.  Typically the case may be different.
-
-  When make deletes files, on posix platforms it writes out 'rm' and the list
-  of files.  On VMS, only the files are writen out, one per line.
-  TODO: VMS
-
-  There may be extra leading white space or additional or missing whitespace
-  in the output of recipes.
-
-  GNU Make uses sys$scratch: for the tempfiles that it creates.
-
-  The OpenVMS CRTL library maps /tmp to sys$scratch if the TMP: logical name
-  does not exist.  As the CRTL may use both sys$scratch: and /tmp internally,
-  if you define the TMP logical name to be different than SYS$SCRATCH:,
-  you may end up with only some temporary files in TMP: and some in SYS$SCRATCH:
-
-  The default include directory for including other makefiles is
-  SYS$SYSROOT:[SYSLIB] (I don't remember why I didn't just use
-  SYS$LIBRARY: instead; maybe it wouldn't work that way).
-  TODO:  A better default may be desired.
-
-  If the device for a file in a recipe does not exist, on OpenVMS an error
-  message of "stat: <file>: no such device or address" will be output.
-
-  Make ignores success, informational, or warning errors (-S-, -I-, or
-  -W-).  But it will stop on -E- and -F- errors. (unless you do something
-  to override this in your makefile, or whatever).
-
-
-Unix compatibilty features:
----------------------------
-
-  If the command 'echo' is seen, any single quotes on the line will be
-  converted to double quotes.
-
-  The variable $(CD) is implemented as a built in Change Directory
-  command. This invokes the 'builtin_cd'  Executing a 'set default'
-  recipe doesn't do the trick, since it only affects the subprocess
-  spawned for that command.
-
-  The 'builtin_cd' is generally expected to be on its own line.
-  The 'builtin_cd' either from the expansion of $(CD) or directly
-  put in a recipe line will be executed before any other commands in
-  that recipe line.  DCL parameter substitution will not work for the
-  'builtin_cd' command.
-
-  Putting a 'builtin_cd' in a pipeline or an IF-THEN line should not be
-  done because the 'builtin_cd' is always executed
-  and executed first.  The directory change is persistent.
-
-  Unix shell style I/O redirection is supported. You can now write lines like:
-  "<tab>mcr sys$disk:[]program.exe < input.txt > output.txt &> error.txt"
-
-  Posix shells have ":" as a null command.  These are now handled.
-  https://savannah.gnu.org/bugs/index.php?41761
-
-  A note on appending the redirected output.  A simple mechanism is
-  implemented to make ">>" work in action lines. In OpenVMS there is no simple
-  feature like ">>" to have DCL command or program output redirected and
-  appended to a file. GNU make for OpenVMS implements the redirection
-  of ">>" by using a command procedure.
-
-  The current algorithm creates the output file if it does not exist and
-  then uses the DCL open/append to extend it.  SYS$OUTPUT is then directed
-  to that file.
-
-  The implementation supports only one redirected append output to a file
-  and that redirection is done before any other commands in that line
-  are executed, so it redirects all output for that command.
-
-  The older implementation wrote the output to a temporary file in
-  in sys$scratch: and then attempted to append the file to the existing file.
-  The temporary file names looked like "CMDxxxxx.". Any time the created
-  command procedure can not complete, this happens. Pressing Ctrl+Y to
-  abort make is one case.
-
-  In case of Ctrl+Y the associated command procedure is left in SYS$SCRATCH:.
-  The command procedures will be named gnv$make_cmd*.com.
-
-  The CtrlY handler now uses $delprc to delete all children. This way also
-  actions with DCL commands will be stopped. As before the CtrlY handler
-  then sends SIGQUIT to itself, which is handled in common code.
-
-  Temporary command files are now deleted in the OpenVMS child termination
-  handler. That deletes them even if a Ctrl+C was pressed.
-  TODO: Does the previous section about >> leaving files still apply?
-
-  The behavior of pressing Ctrl+C is not changed. It still has only an effect,
-  after the current action is terminated. If that doesn't happen or takes too
-  long, Ctrl+Y should be used instead.
-
-
-Build Options:
-
-  Added support to have case sensitive targets and dependencies but to
-  still use case blind file names. This is especially useful for Java
-  makefiles on VMS:
-
-<TAB>.SUFFIXES :
-<TAB>.SUFFIXES : .class .java
-<TAB>.java.class :
-<TAB><TAB>javac "$<"
-<TAB>HelloWorld.class :      HelloWorld.java
-
-  A new macro WANT_CASE_SENSITIVE_TARGETS in config.h-vms was introduced.
-  It needs to be enabled to get this feature; default is disabled.
-  TODO: This should be a run-time setting based on if the process
-  has been set to case sensitive.
-
-
-Unimplemented functionality:
-
-  The new feature "Loadable objects" is not yet supported. If you need it,
-  please send a change request or submit a bug report.
-
-  The new option --output-sync (-O) is accepted but has no effect: GNU make
-  for OpenVMS does not support running multiple commands simultaneously.
-
-
-Self test failures and todos:
------------------------------
-
-  The test harness can not handle testing some of the VMS specific modes
-  because of the features needed for to be set for the Perl to run.
-  Need to find a way to set the VMS features before running make as a
-  child.
-
-  GNU make was not currently translating the OpenVMS encoded POSIX values
-  returned to it back to the Posix values.  I have temporarily modified the
-  Perl test script to compensate for it.  This should be being handled
-  internally to Make.
-  TODO: Verify and update the Perl test script.
-
-  The features/parallelism test was failing. OpenVMS is executing the rules
-  in sequence not in parallel as this feature was not implemented.
-  GNU Make on VMS no longer claims it is implemented.
-  TODO: Implement it.
-
-  Symlink support is not present.  Symlinks are supported by OpenVMS 8.3 and
-  later.
-
-  Error messages should be supressed with the "-" at the beginning of a line.
-  On openVMS they were showing up.  TODO: Is this still an issue?
-
-  The internal vmsify and unixify OpenVMS to/from UNIX are not handling logical
-  names correctly.
-
-
-Build instructions:
-------------------
-
-  Don't use the HP C V7.2-001 compiler, which has an incompatible change
-  how __STDC__ is defined. This results at least in compile time warnings.
-
-Make a 1st version
-       $ @makefile.com  ! ignore any compiler and/or linker warning
-       $ copy make.exe 1st-make.exe
-
-  Use the 1st version to generate a 2nd version as a test.
-       $ mc sys$disk:[]1st-make clean  ! ignore any file not found messages
-       $ mc sys$disk:[]1st-make
-
-  Verify your 2nd version by building Make again.

-Running the tests:
-------------------
-
-  Running the tests on OpenVMS requires the following software to be installed
-  as most of the tests are Unix oriented.
-
-  * Perl 5.18 or later.
-    https://sourceforge.net/projects/vmsperlkit/files/
-  * GNV 2.1.3 + Updates including a minimum of:
-    * Bash 4.3.30
-    * ld_tools 3.0.2
-    * coreutils 8.21
-   https://sourceforge.net/p/gnv/wiki/InstallingGNVPackages/
-   https://sourceforge.net/projects/gnv/files/
-
-   As the test scripts need to create some foreign commands that persist
-   after the test is run, it is recommend that either you use a subprocess or
-   a dedicated login to run the tests.
-
-   To get detailed information for running the tests:
-
-   $ set default [.tests]
-   $ @run_make_tests help
-
-   Running the script with no parameters will run all the tests.
-
-   After the the test script has been run once in a session, assuming
-   that you built make in sys$disk:[make], you can redefined the
-   "bin" logical name as follows:
-
-   $ define bin sys$disk:[make],gnv$gnu:[bin]
-
-   Then you can use Perl to run the scripts.
-
-   $ perl run_make_tests.pl

-This version of GNU make has been tested on:
-  Microsoft Windows 2000/XP/2003/Vista/7/8/10
-It has also been used on Windows 95/98/NT, and on OS/2.
-
-It builds with the MinGW port of GCC (tested with GCC 3.4.2, 4.8.1,
-and 4.9.3).
-
-It also builds with MSVC 2.x, 4.x, 5.x, 6.x, 2005, 2008, 2010, 2012,
-2013, and 2015 as well as with .NET 7.x and .NET 2003.
-
-Building with Guile is supported (tested with Guile 2.0.x).  To build
-with Guile, you will need, in addition to Guile itself, its dependency
-libraries and the pkg-config program.  The latter is used to figure out
-which compilation and link switches and libraries need to be mentioned
-on the compiler command lines to correctly link with Guile.  A Windows
-port of pkg-config can be found on ezwinports site:
-
-  http://sourceforge.net/projects/ezwinports/
-
-The libraries on which Guile depends can vary depending on your
-version and build of Guile.  At the very least, the Boehm's GC library
-will be needed, and typically also GNU MP, libffi, libunistring, and
-libtool's libltdl.  Whoever built the port of Guile you have should
-also provide you with these dependencies or a URL where to download
-them.  A precompiled 32-bit Windows build of Guile is available from
-the ezwinports site mentioned above.
-
-The Windows port of GNU make is maintained jointly by various people.
-It was originally made by Rob Tulloh.
-It is currently maintained by Eli Zaretskii.
-
-
-Do this first, regardless of the build method you choose:
----------------------------------------------------------
-
- 1. Edit config.h.W32 to your liking (especially the few shell-related
-    defines near the end, or HAVE_CASE_INSENSITIVE_FS which corresponds
-    to './configure --enable-case-insensitive-file-system').  (We don't
-    recommend to define HAVE_CASE_INSENSITIVE_FS, but you may wish to
-    consider that if you have a lot of files whose names are in upper
-    case, while Makefile rules are written for lower-case versions.)
-
-
-Building with (MinGW-)GCC using build_w32.bat
----------------------------------------------
-
- 2. Open a W32 command prompt for your installed (MinGW-)GCC, setup a
-    correct PATH and other environment variables for it, then execute ...
-
-        .\build_w32.bat gcc
-
-    This produces gnumake.exe in the GccRel directory.
-
-    If you want a version of GNU make built with debugging enabled,
-    add the --debug option.  Output goes into the GccDebug directory.
-
-    The batch file will probe for Guile installation, and will build
-    gnumake.exe with Guile if it finds it.  If you have Guile
-    installed, but want to build Make without Guile support, type
-
-        .\build_w32.bat --without-guile gcc
-
-
-Building with (MSVC++-)cl using build_w32.bat
----------------------------------------------
-
- 2. Open a command shell, then execute ...
-
-        .\build_w32.bat
-
-    This produces a 64bit Release build of gnumake.exe in .\WinRel, using
-    the compiler found on the %Path%.  If no compiler is found, the batch
-    file will probe your system and choose the newest MSVC version it can
-    find.
-
-    If you want a 32bit version of GNU make, add the --x86 option.
-
-    If you want a Debug build of GNU make, add the --debug option.  Output
-    will go into the .\WinDebug directory.
-
-    The batch file will probe for Guile installation, and will build
-    gnumake.exe with Guile if it finds it.  If Guile is installed,
-    but you prefer to build GNU make without Guile support, add the
-    --without-guile option.
-
-
-Building with (MinGW-)GCC using GNU make
-----------------------------------------
-
- 2. If you already have a version of GNU make available you can use it
-    to build this version.  Open a W32 command prompt for your installed
-    (MinGW-)GCC, setup a correct PATH and other environment variables
-    for it, then execute ...
-
-        make -f Basic.mk TOOLCHAIN=gcc
-
-    This produces GccRel\gnumake.exe.
-    If you want a version of GNU make built with debugging enabled,
-    add the TARGET_TYPE=debug option:
-
-        make -f Basic.mk TOOLCHAIN=gcc TARGET_TYPE=debug
-
-    The makefile doesn't support Guile integration.  Use build_w32.bat
-    if you want to build with Guile support.
-
-
-Building with (MSVC++-)cl using GNU make
-----------------------------------------
-
- 2. If you already have a version of GNU make available you can use it
-    to build this version.  Open a W32 command prompt for your installed
-    (MSVC++-)cl, setup a correct PATH and other environment variables
-    for it (usually via executing vcvars32.bat or vsvars32.bat from the
-    cl-installation, or using a corresponding start menu entry from the
-    cl-installation), then execute ...
-
-        make -f Basic.mk
-
-    This produces an optimized WinRel/gnumake.exe.
-    If you want a version of GNU make built with debugging enabled,
-    add the TARGET_TYPE=debug option:
-
-        make -f Basic.mk TARGET_TYPE=debug
-
-    The makefile doesn't support Guile integration.  Use build_w32.bat
-    if you want to build with Guile support.
-
-
-Running the test suite
-----------------------
-
- 3. You will need an installation of Perl.  Be sure to use a relatively
-    modern version: older versions will sometimes throw spurious errors.
-
-    To run the suite after building using GNU make, use:
-
-        make -f Basic.mk check
-
-    Alternatively if you'd like to run tests by hand, use:
-
-        cd tests
-        .\run_make_tests.bat -make <path-to-make>
-
-    I've found <path-to-make> seems to want forward-slashes in the path.
-    For example if building with .\build_w32.bat non-debug, use:
-
-        cd tests
-        .\run_make_tests.bat -make ../WinRel/gnumake.exe
-
-    I've tested this with the MSYS2 shell and POSIX tools installation
-    that you get by installing Git for Windows.

--- Notes/Caveats --
--------------------
-
-GNU make on Windows 32-bit platforms:
-
-        This version of make is ported natively to Windows32 platforms
-        (Windows NT 3.51, Windows NT 4.0, Windows 2000, Windows XP,
-        Windows 95, and Windows 98). It does not rely on any 3rd party
-        software or add-on packages for building. The only thing
-        needed is a Windows compiler.  Two compilers supported
-        officially are the MinGW port of GNU GCC, and the various
-        versions of the Microsoft C compiler.
-
-        Do not confuse this port of GNU make with other Windows32 projects
-        which provide a GNU make binary. These are separate projects
-        and are not connected to this port effort.
-
-GNU make and sh.exe:
-
-        This port prefers if you have a working sh.exe somewhere on
-        your system. If you don't have sh.exe, the port falls back to
-        MSDOS mode for launching programs (via a batch file).  The
-        MSDOS mode style execution has not been tested that carefully
-        though (The author uses GNU bash as sh.exe).
-
-        There are very few true ports of Bourne shell for NT right now.
-        There is a version of GNU bash available from Cygnus "Cygwin"
-        porting effort (http://www.cygwin.com/).
-        Other possibilities are the MKS version of sh.exe, or building
-        your own with a package like NutCracker (DataFocus) or Portage
-        (Consensys).  Also MinGW includes sh (http://mingw.org/).
-
-GNU make and brain-dead shells (BATCH_MODE_ONLY_SHELL):
-
-        Some versions of Bourne shell do not behave well when invoked
-        as 'sh -c' from CreateProcess().  The main problem is they seem
-        to have a hard time handling quoted strings correctly. This can
-        be circumvented by writing commands to be executed to a batch
-        file and then executing the command by calling 'sh file'.
-
-        To work around this difficulty, this version of make supports
-        a batch mode.  When BATCH_MODE_ONLY_SHELL is defined at compile
-        time, make forces all command lines to be executed via script
-        files instead of by command line.  In this mode you must have a
-        working sh.exe in order to use parallel builds (-j).
-
-        A native Windows32 system with no Bourne shell will also run
-        in batch mode.  All command lines will be put into batch files
-        and executed via $(COMSPEC) (%COMSPEC%).  However, parallel
-        builds ARE supported with Windows shells (cmd.exe and
-        command.com).  See the next section about some peculiarities
-        of parallel builds on Windows.
-
-Support for parallel builds
-
-        Parallel builds (-jN) are supported in this port.  The number of
-        concurrent processes has a hard limit of 4095.
-
-GNU make and Cygnus GNU Windows32 tools:
-
-        Good news! Make now has native support for Cygwin sh. To enable,
-        define the HAVE_CYGWIN_SHELL in config.h and rebuild make
-        from scratch. This version of make tested with B20.1 of Cygwin.
-        Do not define BATCH_MODE_ONLY_SHELL if you use HAVE_CYGWIN_SHELL.
-
-GNU make and the MKS shell:
-
-        There is now semi-official support for the MKS shell. To turn this
-        support on, define HAVE_MKS_SHELL in the config.h.W32 before you
-        build make.  Do not define BATCH_MODE_ONLY_SHELL if you turn
-        on HAVE_MKS_SHELL.
-
-GNU make handling of drive letters in pathnames (PATH, vpath, VPATH):
-
-        There is a caveat that should be noted with respect to handling
-        single character pathnames on Windows systems.  When colon is
-        used in PATH variables, make tries to be smart about knowing when
-        you are using colon as a separator versus colon as a drive
-        letter.  Unfortunately, something as simple as the string 'x:/'
-        could be interpreted 2 ways: (x and /) or (x:/).
-
-        Make chooses to interpret a letter plus colon (e.g. x:/) as a
-        drive letter pathname.  If it is necessary to use single
-        character directories in paths (VPATH, vpath, Path, PATH), the
-        user must do one of two things:
-
-         a. Use semicolon as the separator to disambiguate colon. For
-            example use 'x;/' if you want to say 'x' and '/' are
-            separate components.
-
-         b. Qualify the directory name so that there is more than
-            one character in the path(s) used. For example, none
-            of these settings are ambiguous:
-
-              ./x:./y
-              /some/path/x:/some/path/y
-              x:/some/path/x:x:/some/path/y
-
-        Please note that you are free to mix colon and semi-colon in the
-        specification of paths.  Make is able to figure out the intended
-        result and convert the paths internally to the format needed
-        when interacting with the operating system, providing the path
-        is not within quotes, e.g. "x:/test/test.c".
-
-        You are encouraged to use colon as the separator character.
-        This should ease the pain of deciding how to handle various path
-        problems which exist between platforms.  If colon is used on
-        both Unix and Windows systems, then no ifdef'ing will be
-        necessary in the makefile source.
-
-Pathnames and white space:
-
-        Unlike Unix, Windows 95/NT systems encourage pathnames which
-        contain white space (e.g. C:\Program Files\). These sorts of
-        pathnames are valid on Unix too, but are never encouraged.
-        There is at least one place in make (VPATH/vpath handling) where
-        paths containing white space will simply not work. There may be
-        others too. I chose to not try and port make in such a way so
-        that these sorts of paths could be handled. I offer these
-        suggestions as workarounds:
-
-                1. Use 8.3 notation. i.e. "x:/long~1/", which is actually
-                   "x:\longpathtest".  Type "dir /x" to view these filenames
-                   within the cmd.exe shell.
-                2. Rename the directory so it does not contain white space.
-
-        If you are unhappy with this choice, this is free software
-        and you are free to take a crack at making this work. The code
-        in w32/pathstuff.c and vpath.c would be the places to start.
-
-Pathnames and Case insensitivity:
-
-        Unlike Unix, Windows 95/NT systems are case insensitive but case
-        preserving.  For example if you tell the file system to create a
-        file named "Target", it will preserve the case.  Subsequent access to
-        the file with other case permutations will succeed (i.e. opening a
-        file named "target" or "TARGET" will open the file "Target").
-
-        By default, GNU make retains its case sensitivity when comparing
-        target names and existing files or directories.  It can be
-        configured, however, into a case preserving and case insensitive
-        mode by adding a define for HAVE_CASE_INSENSITIVE_FS to
-        config.h.W32.
-
-        For example, the following makefile will create a file named
-        Target in the directory subdir which will subsequently be used
-        to satisfy the dependency of SUBDIR/DepTarget on SubDir/TARGET.
-        Without HAVE_CASE_INSENSITIVE_FS configured, the dependency link
-        will not be made:
-
-        subdir/Target:
-                touch $@
-
-        SUBDIR/DepTarget: SubDir/TARGET
-                cp $^ $@
-
-        Reliance on this behavior also eliminates the ability of GNU make
-        to use case in comparison of matching rules.  For example, it is
-        not possible to set up a C++ rule using %.C that is different
-        than a C rule using %.c.  GNU make will consider these to be the
-        same rule and will issue a warning.
-
-SAMBA/NTFS/VFAT:
-
-        I have not had any success building the debug version of this
-        package using SAMBA as my file server. The reason seems to be
-        related to the way VC++ 4.0 changes the case name of the pdb
-        filename it is passed on the command line. It seems to change
-        the name always to to lower case. I contend that the VC++
-        compiler should not change the casename of files that are passed
-        as arguments on the command line. I don't think this was a
-        problem in MSVC 2.x, but I know it is a problem in MSVC 4.x.
-
-        The package builds fine on VFAT and NTFS filesystems.
-
-        Most all of the development I have done to date has been using
-        NTFS and long file names. I have not done any considerable work
-        under VFAT. VFAT users may wish to be aware that this port of
-        make does respect case sensitivity.
-
-FAT:
-
-        Version 3.76 added support for FAT filesystems. Make works
-        around some difficulties with stat'ing of files and caching of
-        filenames and directories internally.
-
-Bug reports:
-
-        Please submit bugs via the normal bug reporting mechanism which
-        is described in the GNU make manual and the base README.

-
-GNU make can utilize the Customs library, distributed with Pmake, to
-provide builds distributed across multiple hosts.
-
-In order to utilize this capability, you must first download and build
-the Customs library.  It is contained in the Pmake distribution, which
-can be obtained at:
-
-  ftp://ftp.icsi.berkeley.edu/pub/ai/stolcke/software/
-
-This integration was tested (superficially) with Pmake 2.1.33.
-
-
-BUILDING CUSTOMS
-----------------
-
-First, build pmake and Customs.  You need to build pmake first, because
-Customs require pmake to build.  Unfortunately, this is not trivial;
-please see the pmake and Customs documentation for details.  The best
-place to look for instructions is in the pmake-2.1.33/INSTALL file.
-
-Note that the 2.1.33 Pmake distribution comes with a set of patches to
-GNU make, distributed in the pmake-2.1.33/etc/gnumake/ directory.  These
-patches are based on GNU make 3.75 (there are patches for earlier
-versions of GNU make, also).  The parts of this patchfile which relate
-directly to Customs support have already been incorporated into this
-version of GNU make, so you should _NOT_ apply the patch file.
-
-However, there are a few non-Customs specific (as far as I could tell)
-changes here which are not incorporated (for example, the modification
-to try expanding -lfoo to libfoo.so).  If you rely on these changes
-you'll need to re-apply them by hand.
-
-Install the Customs library and header files according to the
-documentation.  You should also install the man pages (contrary to
-comments in the documentation, they weren't installed automatically for
-me; I had to cd to the 'pmake-2.1.33/doc' directory and run 'pmake
-install' there directly).
-
-
-BUILDING GNU MAKE
------------------
-
-Once you've installed Customs, you can build GNU make to use it.  When
-configuring GNU make, merely use the '--with-customs=DIR' option.
-Provide the directory containing the 'lib' and 'include/customs'
-subdirectories as DIR.  For example, if you installed the customs
-library in /usr/local/lib and the headers in /usr/local/include/customs,
-then you'd pass '--with-customs=/usr/local' as an option to configure.
-
-Run make (or use build.sh) normally to build GNU make as described in
-the INSTALL file.
-
-See the documentation for Customs for information on starting and
-configuring Customs.
-
-
-INVOKING CUSTOMS-IZED GNU MAKE
------------------------------
-
-One thing you should be aware of is that the default build environment
-for Customs requires root permissions.  Practically, this means that GNU
-make must be installed setuid root to use Customs.
-
-If you don't want to do this, you can build Customs such that root
-permissions are not necessary.  Andreas Stolcke <stolcke@speech.sri.com>
-writes:
-
- > pmake, gnumake or any other customs client program is not required to
- > be suid root if customs was compiled WITHOUT the USE_RESERVED_PORTS
- > option in customs/config.h.  Make sure the "customs" service in
- > /etc/services is defined accordingly (port 8231 instead of 1001).
-
- > Not using USE_RESERVED_PORTS means that a user with programming
- > skills could impersonate another user by writing a fake customs
- > client that pretends to be someone other than himself.  See the
- > discussion in etc/SECURITY.
-
-
-PROBLEMS
---------
-
-SunOS 4.1.x:
-  The customs/sprite.h header file #includes the <malloc.h> header
-  files; this conflicts with GNU make's configuration so you'll get a
-  compile error if you use GCC (or any other ANSI-capable C compiler).
-
-  I commented out the #include in sprite.h:107:
-
-    #if defined(sun) || defined(ultrix) || defined(hpux) || defined(sgi)
-    /* #include <malloc.h> */
-    #else
-
-  YMMV.

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
-# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
-#
-# Of course, Automake must honor this variable whenever it calls a
-# tool from the auxiliary directory.  The problem is that $srcdir (and
-# therefore $ac_aux_dir as well) can be either absolute or relative,
-# depending on how configure is run.  This is pretty annoying, since
-# it makes $ac_aux_dir quite unusable in subdirectories: in the top
-# source directory, any form will work fine, but in subdirectories a
-# relative path needs to be adjusted first.
-#
-# $ac_aux_dir/missing
-#    fails when called from a subdirectory if $ac_aux_dir is relative
-# $top_srcdir/$ac_aux_dir/missing
-#    fails if $ac_aux_dir is absolute,
-#    fails when called from a subdirectory in a VPATH build with
-#          a relative $ac_aux_dir
-#
-# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
-# are both prefixed by $srcdir.  In an in-source build this is usually
-# harmless because $srcdir is '.', but things will broke when you
-# start a VPATH build or use an absolute $srcdir.
-#
-# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
-# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
-#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
-# and then we would define $MISSING as
-#   MISSING="\${SHELL} $am_aux_dir/missing"
-# This will work as long as MISSING is not called from configure, because
-# unfortunately $(top_srcdir) has no meaning in configure.
-# However there are other variables, like CC, which are often used in
-# configure, and could therefore not use this "fixed" $ac_aux_dir.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH.  The drawback is that using absolute paths prevent a

-# Configuration subroutine to validate and canonicalize a configuration type.
-# Supply the specified configuration type as an argument.
-# If it is invalid, we print an error message on stderr and exit with code 1.
-# Otherwise, we print the canonical config type on stdout and succeed.

-# This file is supposed to be the same for all GNU packages

-# The goal of this file is to map all the various variations of a given
-# machine specification into a single specification in the form:
-#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
-# or in some cases, the newer four-part form:
-#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

-##   supported by the other compilers which use the 'gcc' depmode.
-## - Using -M directly means running the compiler twice (even worse

-## This next piece of magic avoids the "deleted header file" problem.
-## The problem is that when a header file which appears in a .P file
-## is deleted, the dependency causes make to die (because there is
-## typically no way to rebuild the header).  We avoid this by adding
-## dummy dependencies for each header file.  Too bad gcc doesn't do
-## this for us directly.
-## Some versions of gcc put a space before the ':'.  On the theory
-## that the space means something, we add a space to the output as
-## well.  hp depmode also adds that space, but also prefixes the VPATH
-## to the object.  Take care to not repeat it in the output.

-% To process a Texinfo manual with TeX, it's most reliable to use the
-% texi2dvi shell script that comes with the distribution.  For a simple
-% manual foo.texi, however, you can get away with this:
-%   tex foo.texi
-%   texindex foo.??
-%   tex foo.texi
-%   tex foo.texi
-%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
-% The extra TeX runs get the cross-reference information correct.
-% Sometimes one run after texindex suffices, and sometimes you need more

-% @multitable macros
-% Amy Hendrickson, 8/18/94, 3/6/96
-%
-% @multitable ... @end multitable will make as many columns as desired.
-% Contents of each column will wrap at width given in preamble.  Width
-% can be specified either with sample text given in a template line,
-% or in percent of \hsize, the current width of text on page.
-
-% Table can continue over pages but will only break between lines.
-
-% To make preamble:
-%
-% Either define widths of columns in terms of percent of \hsize:
-%   @multitable @columnfractions .25 .3 .45
-%   @item ...
-%
-%   Numbers following @columnfractions are the percent of the total
-%   current hsize to be used for each column. You may use as many
-%   columns as desired.
-
-
-% Or use a template:
-%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-%   @item ...
-%   using the widest term desired in each column.
-
-% Each new table line starts with @item, each subsequent new column
-% starts with @tab. Empty columns may be produced by supplying @tab's
-% with nothing between them for as many times as empty columns are needed,
-% ie, @tab@tab@tab will produce two empty columns.
-
-% @item, @tab do not need to be on their own lines, but it will not hurt
-% if they are.
-
-% Sample multitable:
-
-%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
-%   @item first col stuff @tab second col stuff @tab third col
-%   @item
-%   first col stuff
-%   @tab
-%   second col stuff
-%   @tab
-%   third col
-%   @item first col stuff @tab second col stuff
-%   @tab Many paragraphs of text may be used in any column.
-%
-%         They will wrap at the width determined by the template.
-%   @item@tab@tab This will be in third column.
-%   @end multitable
-
-% Default dimensions may be reset by user.
-% @multitableparskip is vertical space between paragraphs in table.
-% @multitableparindent is paragraph indent in table.
-% @multitablecolmargin is horizontal space to be left between columns.
-% @multitablelinespace is space to leave between table items, baseline
-%                                                            to baseline.

+   Suppress extern inline with HP-UX cc, as it appears to be broken; see
+   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
+
+   Suppress extern inline with Sun C in standards-conformance mode, as it
+   mishandles inline functions that call each other.  E.g., for 'inline void f
+   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+   'reference to static identifier "f" in extern inline function'.
+   This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
+
+   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+   on configurations that mistakenly use 'static inline' to implement
+   functions or macros in standard C headers like <ctype.h>.  For example,
+   if isdigit is mistakenly implemented via a static inline function,
+   a program containing an extern inline function that calls isdigit
+   may not work since the C standard prohibits extern inline functions
+   from calling static functions (ISO C 99 section 6.7.4.(3).
+   This bug is known to occur on:
+
+     OS X 10.8 and earlier; see:
+     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
+
+     DragonFly; see
+     http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
+
+     FreeBSD; see:
+     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
+
+   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
+   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
+   Assume DragonFly and FreeBSD will be similar.
+
+   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+   inline semantics, unless -fgnu89-inline is used.  It defines a macro
+   __GNUC_STDC_INLINE__ to indicate this situation or a macro
+   __GNUC_GNU_INLINE__ to indicate the opposite situation.
+   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
+   semantics but warns, unless -fgnu89-inline is used:
+     warning: C99 inline functions are not supported; using GNU89
+     warning: to disable this warning use -fgnu89-inline or the gnu_inline
+   function attribute It defines a macro __GNUC_GNU_INLINE__ to indicate this

-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files

-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-

-@c hence no sectioning command or @node.

-Copyright @copyright{} 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.

-PREAMBLE
-
-The purpose of this License is to make a manual, textbook, or other
-functional and useful document @dfn{free} in the sense of freedom: to
-assure everyone the effective freedom to copy and redistribute it,
-with or without modifying it, either commercially or noncommercially.
-Secondarily, this License preserves for the author and publisher a way
-to get credit for their work, while not being considered responsible
-for modifications made by others.
-
-This License is a kind of ``copyleft'', which means that derivative
-works of the document must themselves be free in the same sense.  It
-complements the GNU General Public License, which is a copyleft
-license designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free
-program should come with manuals providing the same freedoms that the
-software does.  But this License is not limited to software manuals;
-it can be used for any textual work, regardless of subject matter or
-whether it is published as a printed book.  We recommend this License
-principally for works whose purpose is instruction or reference.
-
-@item
-APPLICABILITY AND DEFINITIONS
-
-This License applies to any manual or other work, in any medium, that
-contains a notice placed by the copyright holder saying it can be
-distributed under the terms of this License.  Such a notice grants a
-world-wide, royalty-free license, unlimited in duration, to use that
-work under the conditions stated herein.  The ``Document'', below,
-refers to any such manual or work.  Any member of the public is a
-licensee, and is addressed as ``you''.  You accept the license if you
-copy, modify or distribute the work in a way requiring permission
-under copyright law.
-
-A ``Modified Version'' of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-A ``Secondary Section'' is a named appendix or a front-matter section
-of the Document that deals exclusively with the relationship of the
-publishers or authors of the Document to the Document's overall
-subject (or to related matters) and contains nothing that could fall
-directly within that overall subject.  (Thus, if the Document is in
-part a textbook of mathematics, a Secondary Section may not explain
-any mathematics.)  The relationship could be a matter of historical
-connection with the subject or with related matters, or of legal,
-commercial, philosophical, ethical or political position regarding
-them.
-
-The ``Invariant Sections'' are certain Secondary Sections whose titles
-are designated, as being those of Invariant Sections, in the notice
-that says that the Document is released under this License.  If a
-section does not fit the above definition of Secondary then it is not
-allowed to be designated as Invariant.  The Document may contain zero
-Invariant Sections.  If the Document does not identify any Invariant
-Sections then there are none.
-
-The ``Cover Texts'' are certain short passages of text that are listed,
-as Front-Cover Texts or Back-Cover Texts, in the notice that says that
-the Document is released under this License.  A Front-Cover Text may
-be at most 5 words, and a Back-Cover Text may be at most 25 words.
-
-A ``Transparent'' copy of the Document means a machine-readable copy,
-represented in a format whose specification is available to the
-general public, that is suitable for revising the document
-straightforwardly with generic text editors or (for images composed of
-pixels) generic paint programs or (for drawings) some widely available
-drawing editor, and that is suitable for input to text formatters or
-for automatic translation to a variety of formats suitable for input
-to text formatters.  A copy made in an otherwise Transparent file
-format whose markup, or absence of markup, has been arranged to thwart
-or discourage subsequent modification by readers is not Transparent.
-An image format is not Transparent if used for any substantial amount
-of text.  A copy that is not ``Transparent'' is called ``Opaque''.
-
-Examples of suitable formats for Transparent copies include plain
-ASCII without markup, Texinfo input format, La@TeX{} input
-format, SGML or XML using a publicly available
-DTD, and standard-conforming simple HTML,
-PostScript or PDF designed for human modification.  Examples
-of transparent image formats include PNG, XCF and
-JPG@.  Opaque formats include proprietary formats that can be
-read and edited only by proprietary word processors, SGML or
-XML for which the DTD and/or processing tools are
-not generally available, and the machine-generated HTML,
-PostScript or PDF produced by some word processors for
-output purposes only.
-
-The ``Title Page'' means, for a printed book, the title page itself,
-plus such following pages as are needed to hold, legibly, the material
-this License requires to appear in the title page.  For works in
-formats which do not have any title page as such, ``Title Page'' means
-the text near the most prominent appearance of the work's title,
-preceding the beginning of the body of the text.
-
-The ``publisher'' means any person or entity that distributes copies
-of the Document to the public.
-
-A section ``Entitled XYZ'' means a named subunit of the Document whose
-title either is precisely XYZ or contains XYZ in parentheses following
-text that translates XYZ in another language.  (Here XYZ stands for a
-specific section name mentioned below, such as ``Acknowledgements'',
-``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
-of such a section when you modify the Document means that it remains a
-section ``Entitled XYZ'' according to this definition.
-
-The Document may include Warranty Disclaimers next to the notice which
-states that this License applies to the Document.  These Warranty
-Disclaimers are considered to be included by reference in this
-License, but only as regards disclaiming warranties: any other
-implication that these Warranty Disclaimers may have is void and has
-no effect on the meaning of this License.

-VERBATIM COPYING
-
-You may copy and distribute the Document in any medium, either
-commercially or noncommercially, provided that this License, the
-copyright notices, and the license notice saying this License applies
-to the Document are reproduced in all copies, and that you add no other
-conditions whatsoever to those of this License.  You may not use
-technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute.  However, you may accept
-compensation in exchange for copies.  If you distribute a large enough
-number of copies you must also follow the conditions in section 3.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-@item
-COPYING IN QUANTITY
-
-If you publish printed copies (or copies in media that commonly have
-printed covers) of the Document, numbering more than 100, and the
-Document's license notice requires Cover Texts, you must enclose the
-copies in covers that carry, clearly and legibly, all these Cover
-Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
-the back cover.  Both covers must also clearly and legibly identify
-you as the publisher of these copies.  The front cover must present
-the full title with all words of the title equally prominent and
-visible.  You may add other material on the covers in addition.
-Copying with changes limited to the covers, as long as they preserve
-the title of the Document and satisfy these conditions, can be treated
-as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute Opaque copies of the Document numbering
-more than 100, you must either include a machine-readable Transparent
-copy along with each Opaque copy, or state in or with each Opaque copy
-a computer-network location from which the general network-using
-public has access to download using public-standard network protocols
-a complete Transparent copy of the Document, free of added material.
-If you use the latter option, you must take reasonably prudent steps,
-when you begin distribution of Opaque copies in quantity, to ensure
-that this Transparent copy will remain thus accessible at the stated
-location until at least one year after the last time you distribute an
-Opaque copy (directly or through your agents or retailers) of that
-edition to the public.
-
-It is requested, but not required, that you contact the authors of the
-Document well before redistributing any large number of copies, to give
-them a chance to provide you with an updated version of the Document.
-
-@item
-MODIFICATIONS
-
-You may copy and distribute a Modified Version of the Document under
-the conditions of sections 2 and 3 above, provided that you release
-the Modified Version under precisely this License, with the Modified
-Version filling the role of the Document, thus licensing distribution
-and modification of the Modified Version to whoever possesses a copy
-of it.  In addition, you must do these things in the Modified Version:
-
-@enumerate A
-@item
-Use in the Title Page (and on the covers, if any) a title distinct
-from that of the Document, and from those of previous versions
-(which should, if there were any, be listed in the History section
-of the Document).  You may use the same title as a previous version
-if the original publisher of that version gives permission.
-
-@item
-List on the Title Page, as authors, one or more persons or entities
-responsible for authorship of the modifications in the Modified
-Version, together with at least five of the principal authors of the
-Document (all of its principal authors, if it has fewer than five),
-unless they release you from this requirement.
-
-@item
-State on the Title page the name of the publisher of the
-Modified Version, as the publisher.
-
-@item
-Preserve all the copyright notices of the Document.
-
-@item
-Add an appropriate copyright notice for your modifications
-adjacent to the other copyright notices.
-
-@item
-Include, immediately after the copyright notices, a license notice
-giving the public permission to use the Modified Version under the
-terms of this License, in the form shown in the Addendum below.
-
-@item
-Preserve in that license notice the full lists of Invariant Sections
-and required Cover Texts given in the Document's license notice.
-
-@item
-Include an unaltered copy of this License.
-
-@item
-Preserve the section Entitled ``History'', Preserve its Title, and add
-to it an item stating at least the title, year, new authors, and
-publisher of the Modified Version as given on the Title Page.  If
-there is no section Entitled ``History'' in the Document, create one
-stating the title, year, authors, and publisher of the Document as
-given on its Title Page, then add an item describing the Modified
-Version as stated in the previous sentence.
-
-@item
-Preserve the network location, if any, given in the Document for
-public access to a Transparent copy of the Document, and likewise
-the network locations given in the Document for previous versions
-it was based on.  These may be placed in the ``History'' section.
-You may omit a network location for a work that was published at
-least four years before the Document itself, or if the original
-publisher of the version it refers to gives permission.
-
-@item
-For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
-the Title of the section, and preserve in the section all the
-substance and tone of each of the contributor acknowledgements and/or
-dedications given therein.
-
-@item
-Preserve all the Invariant Sections of the Document,
-unaltered in their text and in their titles.  Section numbers
-or the equivalent are not considered part of the section titles.
-
-@item
-Delete any section Entitled ``Endorsements''.  Such a section
-may not be included in the Modified Version.
-
-@item
-Do not retitle any existing section to be Entitled ``Endorsements'' or
-to conflict in title with any Invariant Section.
-
-@item
-Preserve any Warranty Disclaimers.
-@end enumerate
-
-If the Modified Version includes new front-matter sections or
-appendices that qualify as Secondary Sections and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant.  To do this, add their titles to the
-list of Invariant Sections in the Modified Version's license notice.
-These titles must be distinct from any other section titles.
-
-You may add a section Entitled ``Endorsements'', provided it contains
-nothing but endorsements of your Modified Version by various
-parties---for example, statements of peer review or that the text has
-been approved by an organization as the authoritative definition of a
-standard.
-
-You may add a passage of up to five words as a Front-Cover Text, and a
-passage of up to 25 words as a Back-Cover Text, to the end of the list
-of Cover Texts in the Modified Version.  Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or
-through arrangements made by) any one entity.  If the Document already
-includes a cover text for the same cover, previously added by you or
-by arrangement made by the same entity you are acting on behalf of,
-you may not add another; but you may replace the old one, on explicit
-permission from the previous publisher that added the old one.
-
-The author(s) and publisher(s) of the Document do not by this License
-give permission to use their names for publicity for or to assert or
-imply endorsement of any Modified Version.
-
-@item
-COMBINING DOCUMENTS
-
-You may combine the Document with other documents released under this
-License, under the terms defined in section 4 above for modified
-versions, provided that you include in the combination all of the
-Invariant Sections of all of the original documents, unmodified, and
-list them all as Invariant Sections of your combined work in its
-license notice, and that you preserve all their Warranty Disclaimers.
-
-The combined work need only contain one copy of this License, and
-multiple identical Invariant Sections may be replaced with a single
-copy.  If there are multiple Invariant Sections with the same name but
-different contents, make the title of each such section unique by
-adding at the end of it, in parentheses, the name of the original
-author or publisher of that section if known, or else a unique number.
-Make the same adjustment to the section titles in the list of
-Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections Entitled ``History''
-in the various original documents, forming one section Entitled
-``History''; likewise combine any sections Entitled ``Acknowledgements'',
-and any sections Entitled ``Dedications''.  You must delete all
-sections Entitled ``Endorsements.''
-
-@item
-COLLECTIONS OF DOCUMENTS
-
-You may make a collection consisting of the Document and other documents
-released under this License, and replace the individual copies of this
-License in the various documents with a single copy that is included in
-the collection, provided that you follow the rules of this License for
-verbatim copying of each of the documents in all other respects.
-
-You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-
-@item
-AGGREGATION WITH INDEPENDENT WORKS
-
-A compilation of the Document or its derivatives with other separate
-and independent documents or works, in or on a volume of a storage or
-distribution medium, is called an ``aggregate'' if the copyright
-resulting from the compilation is not used to limit the legal rights
-of the compilation's users beyond what the individual works permit.
-When the Document is included in an aggregate, this License does not
-apply to the other works in the aggregate which are not themselves
-derivative works of the Document.
-
-If the Cover Text requirement of section 3 is applicable to these
-copies of the Document, then if the Document is less than one half of
-the entire aggregate, the Document's Cover Texts may be placed on
-covers that bracket the Document within the aggregate, or the
-electronic equivalent of covers if the Document is in electronic form.
-Otherwise they must appear on printed covers that bracket the whole
-aggregate.
-
-@item
-TRANSLATION
-
-Translation is considered a kind of modification, so you may
-distribute translations of the Document under the terms of section 4.
-Replacing Invariant Sections with translations requires special
-permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections.  You may include a
-translation of this License, and all the license notices in the
-Document, and any Warranty Disclaimers, provided that you also include
-the original English version of this License and the original versions
-of those notices and disclaimers.  In case of a disagreement between
-the translation and the original version of this License or a notice
-or disclaimer, the original version will prevail.
-
-If a section in the Document is Entitled ``Acknowledgements'',
-``Dedications'', or ``History'', the requirement (section 4) to Preserve
-its Title (section 1) will typically require changing the actual
-title.
-
-@item
-TERMINATION
-
-You may not copy, modify, sublicense, or distribute the Document
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense, or distribute it is void, and
-will automatically terminate your rights under this License.
-
-However, if you cease all violation of this License, then your license
-from a particular copyright holder is reinstated (a) provisionally,
-unless and until the copyright holder explicitly and finally
-terminates your license, and (b) permanently, if the copyright holder
-fails to notify you of the violation by some reasonable means prior to
-60 days after the cessation.
-
-Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, receipt of a copy of some or all of the same material does
-not give you any rights to use it.
-
-@item
-FUTURE REVISIONS OF THIS LICENSE
-
-The Free Software Foundation may publish new, revised versions
-of the GNU Free Documentation License from time to time.  Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.  See
-@uref{https://www.gnu.org/copyleft/}.
-
-Each version of the License is given a distinguishing version number.
-If the Document specifies that a particular numbered version of this
-License ``or any later version'' applies to it, you have the option of
-following the terms and conditions either of that specified version or
-of any later version that has been published (not as a draft) by the
-Free Software Foundation.  If the Document does not specify a version
-number of this License, you may choose any version ever published (not
-as a draft) by the Free Software Foundation.  If the Document
-specifies that a proxy can decide which future versions of this
-License can be used, that proxy's public statement of acceptance of a
-version permanently authorizes you to choose that version for the
-Document.

-RELICENSING
-
-``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
-World Wide Web server that publishes copyrightable works and also
-provides prominent facilities for anybody to edit those works.  A
-public wiki that anybody can edit is an example of such a server.  A
-``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
-site means any set of copyrightable works thus published on the MMC
-site.
-
-``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
-license published by Creative Commons Corporation, a not-for-profit
-corporation with a principal place of business in San Francisco,
-California, as well as future copyleft versions of that license
-published by that same organization.
-
-``Incorporate'' means to publish or republish a Document, in whole or
-in part, as part of another Document.
-
-An MMC is ``eligible for relicensing'' if it is licensed under this
-License, and if all works that were first published under this License
-somewhere other than this MMC, and subsequently incorporated in whole
-or in part into the MMC, (1) had no cover texts or invariant sections,
-and (2) were thus incorporated prior to November 1, 2008.
-
-The operator of an MMC Site may republish an MMC contained in the site
-under CC-BY-SA on the same site at any time before August 1, 2009,
-provided the MMC is eligible for relicensing.

-@end menu
-
-@node Makefile Basics
-@section General Conventions for Makefiles
-
-Every Makefile should contain this line:
-
-@example
-SHELL = /bin/sh
-@end example
-
-@noindent
-to avoid trouble on systems where the @code{SHELL} variable might be
-inherited from the environment.  (This is never a problem with GNU
-@code{make}.)
-
-Different @code{make} programs have incompatible suffix lists and
-implicit rules, and this sometimes creates confusion or misbehavior.  So
-it is a good idea to set the suffix list explicitly using only the
-suffixes you need in the particular Makefile, like this:
-
-@example
-.SUFFIXES:
-.SUFFIXES: .c .o
-@end example
-
-@noindent
-The first line clears out the suffix list, the second introduces all
-suffixes which may be subject to implicit rules in this Makefile.
-
-Don't assume that @file{.} is in the path for command execution.  When
-you need to run programs that are a part of your package during the
-make, please make sure that it uses @file{./} if the program is built as
-part of the make or @file{$(srcdir)/} if the file is an unchanging part
-of the source code.  Without one of these prefixes, the current search
-path is used.
-
-The distinction between @file{./} (the @dfn{build directory}) and
-@file{$(srcdir)/} (the @dfn{source directory}) is important because
-users can build in a separate directory using the @samp{--srcdir} option
-to @file{configure}.  A rule of the form:
-
-@smallexample
-foo.1 : foo.man sedscript
-        sed -f sedscript foo.man > foo.1
-@end smallexample
-
-@noindent
-will fail when the build directory is not the source directory, because
-@file{foo.man} and @file{sedscript} are in the source directory.
-
-When using GNU @code{make}, relying on @samp{VPATH} to find the source
-file will work in the case where there is a single dependency file,
-since the @code{make} automatic variable @samp{$<} will represent the
-source file wherever it is.  (Many versions of @code{make} set @samp{$<}
-only in implicit rules.)  A Makefile target like
-
-@smallexample
-foo.o : bar.c
-        $(CC) -I. -I$(srcdir) $(CFLAGS) -c bar.c -o foo.o
-@end smallexample
-
-@noindent
-should instead be written as
-
-@smallexample
-foo.o : bar.c
-        $(CC) -I. -I$(srcdir) $(CFLAGS) -c $< -o $@@
-@end smallexample
-
-@noindent
-in order to allow @samp{VPATH} to work correctly.  When the target has
-multiple dependencies, using an explicit @samp{$(srcdir)} is the easiest
-way to make the rule work well.  For example, the target above for
-@file{foo.1} is best written as:
-
-@smallexample
-foo.1 : foo.man sedscript
-        sed -f $(srcdir)/sedscript $(srcdir)/foo.man > $@@
-@end smallexample
-
-GNU distributions usually contain some files which are not source
-files---for example, Info files, and the output from Autoconf, Automake,
-Bison or Flex.  Since these files normally appear in the source
-directory, they should always appear in the source directory, not in the
-build directory.  So Makefile rules to update them should put the
-updated files in the source directory.
-
-However, if a file does not appear in the distribution, then the
-Makefile should not put it in the source directory, because building a
-program in ordinary circumstances should not modify the source directory
-in any way.
-
-Try to make the build and installation targets, at least (and all their
-subtargets) work correctly with a parallel @code{make}.
-
-@node Utilities in Makefiles
-@section Utilities in Makefiles
-
-Write the Makefile commands (and any shell scripts, such as
-@code{configure}) to run under @code{sh} (both the traditional Bourne
-shell and the @sc{posix} shell), not @code{csh}.  Don't use any
-special features of @code{ksh} or @code{bash}, or @sc{posix} features
-not widely supported in traditional Bourne @code{sh}.
-
-The @code{configure} script and the Makefile rules for building and
-installation should not use any utilities directly except these:
-
-@c dd find
-@c gunzip gzip md5sum
-@c mkfifo mknod tee uname
-
-@example
-awk cat cmp cp diff echo egrep expr false grep install-info ln ls
-mkdir mv printf pwd rm rmdir sed sleep sort tar test touch tr true
-@end example
-
-Compression programs such as @code{gzip} can be used in the
-@code{dist} rule.
-
-Generally, stick to the widely-supported (usually
-@sc{posix}-specified) options and features of these programs.  For
-example, don't use @samp{mkdir -p}, convenient as it may be, because a
-few systems don't support it at all and with others, it is not safe
-for parallel execution.  For a list of known incompatibilities, see
-@ref{Portable Shell, Portable Shell Programming,, autoconf, Autoconf}.
-
-
-It is a good idea to avoid creating symbolic links in makefiles, since a
-few file systems don't support them.
-
-The Makefile rules for building and installation can also use compilers
-and related programs, but should do so via @code{make} variables so that the
-user can substitute alternatives.  Here are some of the programs we
-mean:
-
-@example
-ar bison cc flex install ld ldconfig lex
-make makeinfo ranlib texi2dvi yacc
-@end example
-
-Use the following @code{make} variables to run those programs:
-
-@example
-$(AR) $(BISON) $(CC) $(FLEX) $(INSTALL) $(LD) $(LDCONFIG) $(LEX)
-$(MAKE) $(MAKEINFO) $(RANLIB) $(TEXI2DVI) $(YACC)
-@end example
-
-When you use @code{ranlib} or @code{ldconfig}, you should make sure
-nothing bad happens if the system does not have the program in question.
-Arrange to ignore an error from that command, and print a message before
-the command to tell the user that failure of this command does not mean
-a problem.  (The Autoconf @samp{AC_PROG_RANLIB} macro can help with
-this.)
-
-If you use symbolic links, you should implement a fallback for systems
-that don't have symbolic links.
-
-Additional utilities that can be used via Make variables are:
-
-@example
-chgrp chmod chown mknod
-@end example
-
-It is ok to use other utilities in Makefile portions (or scripts)
-intended only for particular systems where you know those utilities
-exist.
-
-@node Command Variables
-@section Variables for Specifying Commands
-
-Makefiles should provide variables for overriding certain commands, options,
-and so on.
-
-In particular, you should run most utility programs via variables.
-Thus, if you use Bison, have a variable named @code{BISON} whose default
-value is set with @samp{BISON = bison}, and refer to it with
-@code{$(BISON)} whenever you need to use Bison.
-
-File management utilities such as @code{ln}, @code{rm}, @code{mv}, and
-so on, need not be referred to through variables in this way, since users
-don't need to replace them with other programs.
-
-Each program-name variable should come with an options variable that is
-used to supply options to the program.  Append @samp{FLAGS} to the
-program-name variable name to get the options variable name---for
-example, @code{BISONFLAGS}.  (The names @code{CFLAGS} for the C
-compiler, @code{YFLAGS} for yacc, and @code{LFLAGS} for lex, are
-exceptions to this rule, but we keep them because they are standard.)
-Use @code{CPPFLAGS} in any compilation command that runs the
-preprocessor, and use @code{LDFLAGS} in any compilation command that
-does linking as well as in any direct use of @code{ld}.
-
-If there are C compiler options that @emph{must} be used for proper
-compilation of certain files, do not include them in @code{CFLAGS}.
-Users expect to be able to specify @code{CFLAGS} freely themselves.
-Instead, arrange to pass the necessary options to the C compiler
-independently of @code{CFLAGS}, by writing them explicitly in the
-compilation commands or by defining an implicit rule, like this:
-
-@smallexample
-CFLAGS = -g
-ALL_CFLAGS = -I. $(CFLAGS)
-.c.o:
-        $(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $<
-@end smallexample
-
-Do include the @samp{-g} option in @code{CFLAGS}, because that is not
-@emph{required} for proper compilation.  You can consider it a default
-that is only recommended.  If the package is set up so that it is
-compiled with GCC by default, then you might as well include @samp{-O}
-in the default value of @code{CFLAGS} as well.
-
-Put @code{CFLAGS} last in the compilation command, after other variables
-containing compiler options, so the user can use @code{CFLAGS} to
-override the others.
-
-@code{CFLAGS} should be used in every invocation of the C compiler,
-both those which do compilation and those which do linking.
-
-Every Makefile should define the variable @code{INSTALL}, which is the
-basic command for installing a file into the system.
-
-Every Makefile should also define the variables @code{INSTALL_PROGRAM}
-and @code{INSTALL_DATA}.  (The default for @code{INSTALL_PROGRAM} should
-be @code{$(INSTALL)}; the default for @code{INSTALL_DATA} should be
-@code{$@{INSTALL@} -m 644}.)  Then it should use those variables as the
-commands for actual installation, for executables and non-executables
-respectively.  Minimal use of these variables is as follows:
-
-@example
-$(INSTALL_PROGRAM) foo $(bindir)/foo
-$(INSTALL_DATA) libfoo.a $(libdir)/libfoo.a
-@end example
-
-However, it is preferable to support a @code{DESTDIR} prefix on the
-target files, as explained in the next section.
-
-It is acceptable, but not required, to install multiple files in one
-command, with the final argument being a directory, as in:
-
-@example
-$(INSTALL_PROGRAM) foo bar baz $(bindir)
-@end example
-
-
-@node DESTDIR
-@section @code{DESTDIR}: Support for Staged Installs
-
-@vindex DESTDIR
-@cindex staged installs
-@cindex installations, staged
-
-@code{DESTDIR} is a variable prepended to each installed target file,
-like this:
-
-@example
-$(INSTALL_PROGRAM) foo $(DESTDIR)$(bindir)/foo
-$(INSTALL_DATA) libfoo.a $(DESTDIR)$(libdir)/libfoo.a
-@end example
-
-The @code{DESTDIR} variable is specified by the user on the @code{make}
-command line as an absolute file name.  For example:
-
-@example
-make DESTDIR=/tmp/stage install
-@end example
-
-@noindent
-@code{DESTDIR} should be supported only in the @code{install*} and
-@code{uninstall*} targets, as those are the only targets where it is
-useful.
-
-If your installation step would normally install
-@file{/usr/local/bin/foo} and @file{/usr/@/local/@/lib/@/libfoo.a}, then an
-installation invoked as in the example above would install
-@file{/tmp/stage/usr/local/bin/foo} and
-@file{/tmp/stage/usr/local/lib/libfoo.a} instead.
-
-Prepending the variable @code{DESTDIR} to each target in this way
-provides for @dfn{staged installs}, where the installed files are not
-placed directly into their expected location but are instead copied
-into a temporary location (@code{DESTDIR}).  However, installed files
-maintain their relative directory structure and any embedded file names
-will not be modified.
-
-You should not set the value of @code{DESTDIR} in your @file{Makefile}
-at all; then the files are installed into their expected locations by
-default.  Also, specifying @code{DESTDIR} should not change the
-operation of the software in any way, so its value should not be
-included in any file contents.
-
-@code{DESTDIR} support is commonly used in package creation.  It is
-also helpful to users who want to understand what a given package will
-install where, and to allow users who don't normally have permissions
-to install into protected areas to build and install before gaining
-those permissions.  Finally, it can be useful with tools such as
-@code{stow}, where code is installed in one place but made to appear
-to be installed somewhere else using symbolic links or special mount
-operations.  So, we strongly recommend GNU packages support
-@code{DESTDIR}, though it is not an absolute requirement.
-
-
-@node Directory Variables
-@section Variables for Installation Directories
-
-Installation directories should always be named by variables, so it is
-easy to install in a nonstandard place.  The standard names for these
-variables and the values they should have in GNU packages are
-described below.  They are based on a standard file system layout;
-variants of it are used in GNU/Linux and other modern operating
-systems.
-
-Installers are expected to override these values when calling
-@command{make} (e.g., @kbd{make prefix=/usr install}) or
-@command{configure} (e.g., @kbd{configure --prefix=/usr}).  GNU
-packages should not try to guess which value should be appropriate for
-these variables on the system they are being installed onto: use the
-default settings specified here so that all GNU packages behave
-identically, allowing the installer to achieve any desired layout.
-
-@cindex directories, creating installation
-@cindex installation directories, creating
-All installation directories, and their parent directories, should be
-created (if necessary) before they are installed into.
-
-These first two variables set the root for the installation.  All the
-other installation directories should be subdirectories of one of
-these two, and nothing should be directly installed into these two
-directories.
-
-@table @code
-@item prefix
-@vindex prefix
-A prefix used in constructing the default values of the variables listed
-below.  The default value of @code{prefix} should be @file{/usr/local}.
-When building the complete GNU system, the prefix will be empty and
-@file{/usr} will be a symbolic link to @file{/}.
-(If you are using Autoconf, write it as @samp{@@prefix@@}.)
-
-Running @samp{make install} with a different value of @code{prefix} from
-the one used to build the program should @emph{not} recompile the
-program.
-
-@item exec_prefix
-@vindex exec_prefix
-A prefix used in constructing the default values of some of the
-variables listed below.  The default value of @code{exec_prefix} should
-be @code{$(prefix)}.
-(If you are using Autoconf, write it as @samp{@@exec_prefix@@}.)
-
-Generally, @code{$(exec_prefix)} is used for directories that contain
-machine-specific files (such as executables and subroutine libraries),
-while @code{$(prefix)} is used directly for other directories.
-
-Running @samp{make install} with a different value of @code{exec_prefix}
-from the one used to build the program should @emph{not} recompile the
-program.
-@end table
-
-Executable programs are installed in one of the following directories.
-
-@table @code
-@item bindir
-@vindex bindir
-The directory for installing executable programs that users can run.
-This should normally be @file{/usr/local/bin}, but write it as
-@file{$(exec_prefix)/bin}.
-(If you are using Autoconf, write it as @samp{@@bindir@@}.)
-
-@item sbindir
-@vindex sbindir
-The directory for installing executable programs that can be run from
-the shell, but are only generally useful to system administrators.  This
-should normally be @file{/usr/local/sbin}, but write it as
-@file{$(exec_prefix)/sbin}.
-(If you are using Autoconf, write it as @samp{@@sbindir@@}.)
-
-@item libexecdir
-@vindex libexecdir
-@comment This paragraph adjusted to avoid overfull hbox --roland 5jul94
-The directory for installing executable programs to be run by other
-programs rather than by users.  This directory should normally be
-@file{/usr/local/libexec}, but write it as @file{$(exec_prefix)/libexec}.
-(If you are using Autoconf, write it as @samp{@@libexecdir@@}.)
-
-The definition of @samp{libexecdir} is the same for all packages, so
-you should install your data in a subdirectory thereof.  Most packages
-install their data under @file{$(libexecdir)/@var{package-name}/},
-possibly within additional subdirectories thereof, such as
-@file{$(libexecdir)/@var{package-name}/@var{machine}/@var{version}}.
-@end table
-
-Data files used by the program during its execution are divided into
-categories in two ways.
-
-@itemize @bullet
-@item
-Some files are normally modified by programs; others are never normally
-modified (though users may edit some of these).
-
-@item
-Some files are architecture-independent and can be shared by all
-machines at a site; some are architecture-dependent and can be shared
-only by machines of the same kind and operating system; others may never
-be shared between two machines.
-@end itemize
-
-This makes for six different possibilities.  However, we want to
-discourage the use of architecture-dependent files, aside from object
-files and libraries.  It is much cleaner to make other data files
-architecture-independent, and it is generally not hard.
-
-Here are the variables Makefiles should use to specify directories
-to put these various kinds of files in:
-
-@table @samp
-@item datarootdir
-The root of the directory tree for read-only architecture-independent
-data files.  This should normally be @file{/usr/local/share}, but
-write it as @file{$(prefix)/share}.  (If you are using Autoconf, write
-it as @samp{@@datarootdir@@}.)  @samp{datadir}'s default value is
-based on this variable; so are @samp{infodir}, @samp{mandir}, and
-others.
-
-@item datadir
-The directory for installing idiosyncratic read-only
-architecture-independent data files for this program.  This is usually
-the same place as @samp{datarootdir}, but we use the two separate
-variables so that you can move these program-specific files without
-altering the location for Info files, man pages, etc.
-
-@c raggedright  (not until next Texinfo release)
-This should normally be @file{/usr/local/share}, but write it as
-@file{$(datarootdir)}.  (If you are using Autoconf, write it as
-@samp{@@datadir@@}.)
-@c end raggedright
-
-The definition of @samp{datadir} is the same for all packages, so you
-should install your data in a subdirectory thereof.  Most packages
-install their data under @file{$(datadir)/@var{package-name}/}.
-
-@item sysconfdir
-The directory for installing read-only data files that pertain to a
-single machine--that is to say, files for configuring a host.  Mailer
-and network configuration files, @file{/etc/passwd}, and so forth belong
-here.  All the files in this directory should be ordinary ASCII text
-files.  This directory should normally be @file{/usr/local/etc}, but
-write it as @file{$(prefix)/etc}.
-(If you are using Autoconf, write it as @samp{@@sysconfdir@@}.)
-
-Do not install executables here in this directory (they probably belong
-in @file{$(libexecdir)} or @file{$(sbindir)}).  Also do not install
-files that are modified in the normal course of their use (programs
-whose purpose is to change the configuration of the system excluded).
-Those probably belong in @file{$(localstatedir)}.
-
-@item sharedstatedir
-The directory for installing architecture-independent data files which
-the programs modify while they run.  This should normally be
-@file{/usr/local/com}, but write it as @file{$(prefix)/com}.
-(If you are using Autoconf, write it as @samp{@@sharedstatedir@@}.)
-
-@item localstatedir
-The directory for installing data files which the programs modify while
-they run, and that pertain to one specific machine.  Users should never
-need to modify files in this directory to configure the package's
-operation; put such configuration information in separate files that go
-in @file{$(datadir)} or @file{$(sysconfdir)}.  @file{$(localstatedir)}
-should normally be @file{/usr/local/var}, but write it as
-@file{$(prefix)/var}.
-(If you are using Autoconf, write it as @samp{@@localstatedir@@}.)
-
-@item runstatedir
-The directory for installing data files which the programs modify
-while they run, that pertain to one specific machine, and which need
-not persist longer than the execution of the program---which is
-generally long-lived, for example, until the next reboot.  PID files
-for system daemons are a typical use.  In addition, this directory
-should not be cleaned except perhaps at reboot, while the general
-@file{/tmp} (@code{TMPDIR}) may be cleaned arbitrarily.  This should
-normally be @file{/var/run}, but write it as
-@file{$(localstatedir)/run}.  Having it as a separate variable allows
-the use of @file{/run} if desired, for example.  (If you are using
-Autoconf 2.70 or later, write it as @samp{@@runstatedir@@}.)
-@end table
-
-These variables specify the directory for installing certain specific
-types of files, if your program has them.  Every GNU package should
-have Info files, so every program needs @samp{infodir}, but not all
-need @samp{libdir} or @samp{lispdir}.
-
-@table @samp
-@item includedir
-The directory for installing header files to be included by user
-programs with the C @samp{#include} preprocessor directive.  This
-should normally be @file{/usr/local/include}, but write it as
-@file{$(prefix)/include}.
-(If you are using Autoconf, write it as @samp{@@includedir@@}.)
-
-Most compilers other than GCC do not look for header files in directory
-@file{/usr/local/include}.  So installing the header files this way is
-only useful with GCC.  Sometimes this is not a problem because some
-libraries are only really intended to work with GCC.  But some libraries
-are intended to work with other compilers.  They should install their
-header files in two places, one specified by @code{includedir} and one
-specified by @code{oldincludedir}.
-
-@item oldincludedir
-The directory for installing @samp{#include} header files for use with
-compilers other than GCC.  This should normally be @file{/usr/include}.
-(If you are using Autoconf, you can write it as @samp{@@oldincludedir@@}.)
-
-The Makefile commands should check whether the value of
-@code{oldincludedir} is empty.  If it is, they should not try to use
-it; they should cancel the second installation of the header files.
-
-A package should not replace an existing header in this directory unless
-the header came from the same package.  Thus, if your Foo package
-provides a header file @file{foo.h}, then it should install the header
-file in the @code{oldincludedir} directory if either (1) there is no
-@file{foo.h} there or (2) the @file{foo.h} that exists came from the Foo
-package.
-
-To tell whether @file{foo.h} came from the Foo package, put a magic
-string in the file---part of a comment---and @code{grep} for that string.
-
-@item docdir
-The directory for installing documentation files (other than Info) for
-this package.  By default, it should be
-@file{/usr/local/share/doc/@var{yourpkg}}, but it should be written as
-@file{$(datarootdir)/doc/@var{yourpkg}}.  (If you are using Autoconf,
-write it as @samp{@@docdir@@}.)  The @var{yourpkg} subdirectory, which
-may include a version number, prevents collisions among files with
-common names, such as @file{README}.
-
-@item infodir
-The directory for installing the Info files for this package.  By
-default, it should be @file{/usr/local/share/info}, but it should be
-written as @file{$(datarootdir)/info}.  (If you are using Autoconf,
-write it as @samp{@@infodir@@}.)  @code{infodir} is separate from
-@code{docdir} for compatibility with existing practice.
-
-@item htmldir
-@itemx dvidir
-@itemx pdfdir
-@itemx psdir
-Directories for installing documentation files in the particular
-format.  They should all be set to @code{$(docdir)} by default.  (If
-you are using Autoconf, write them as @samp{@@htmldir@@},
-@samp{@@dvidir@@}, etc.)  Packages which supply several translations
-of their documentation should install them in
-@samp{$(htmldir)/}@var{ll}, @samp{$(pdfdir)/}@var{ll}, etc. where
-@var{ll} is a locale abbreviation such as @samp{en} or @samp{pt_BR}.
-
-@item libdir
-The directory for object files and libraries of object code.  Do not
-install executables here, they probably ought to go in @file{$(libexecdir)}
-instead.  The value of @code{libdir} should normally be
-@file{/usr/local/lib}, but write it as @file{$(exec_prefix)/lib}.
-(If you are using Autoconf, write it as @samp{@@libdir@@}.)
-
-@item lispdir
-The directory for installing any Emacs Lisp files in this package.  By
-default, it should be @file{/usr/local/share/emacs/site-lisp}, but it
-should be written as @file{$(datarootdir)/emacs/site-lisp}.
-
-If you are using Autoconf, write the default as @samp{@@lispdir@@}.
-In order to make @samp{@@lispdir@@} work, you need the following lines
-in your @file{configure.ac} file:
-
-@example
-lispdir='$@{datarootdir@}/emacs/site-lisp'
-AC_SUBST(lispdir)
-@end example
-
-@item localedir
-The directory for installing locale-specific message catalogs for this
-package.  By default, it should be @file{/usr/local/share/locale}, but
-it should be written as @file{$(datarootdir)/locale}.  (If you are
-using Autoconf, write it as @samp{@@localedir@@}.)  This directory
-usually has a subdirectory per locale.
-@end table
-
-Unix-style man pages are installed in one of the following:
-
-@table @samp
-@item mandir
-The top-level directory for installing the man pages (if any) for this
-package.  It will normally be @file{/usr/local/share/man}, but you
-should write it as @file{$(datarootdir)/man}.  (If you are using
-Autoconf, write it as @samp{@@mandir@@}.)
-
-@item man1dir
-The directory for installing section 1 man pages.  Write it as
-@file{$(mandir)/man1}.
-@item man2dir
-The directory for installing section 2 man pages.  Write it as
-@file{$(mandir)/man2}
-@item @dots{}
-
-@strong{Don't make the primary documentation for any GNU software be a
-man page.  Write a manual in Texinfo instead.  Man pages are just for
-the sake of people running GNU software on Unix, which is a secondary
-application only.}
-
-@item manext
-The file name extension for the installed man page.  This should contain
-a period followed by the appropriate digit; it should normally be @samp{.1}.
-
-@item man1ext
-The file name extension for installed section 1 man pages.
-@item man2ext
-The file name extension for installed section 2 man pages.
-@item @dots{}
-Use these names instead of @samp{manext} if the package needs to install man
-pages in more than one section of the manual.
-@end table
-
-And finally, you should set the following variable:
-
-@table @samp
-@item srcdir
-The directory for the sources being compiled.  The value of this
-variable is normally inserted by the @code{configure} shell script.
-(If you are using Autoconf, use @samp{srcdir = @@srcdir@@}.)
-@end table
-
-For example:
-
-@smallexample
-@c I have changed some of the comments here slightly to fix an overfull
-@c hbox, so the make manual can format correctly. --roland
-# Common prefix for installation directories.
-# NOTE: This directory must exist when you start the install.
-prefix = /usr/local
-datarootdir = $(prefix)/share
-datadir = $(datarootdir)
-exec_prefix = $(prefix)
-# Where to put the executable for the command 'gcc'.
-bindir = $(exec_prefix)/bin
-# Where to put the directories used by the compiler.
-libexecdir = $(exec_prefix)/libexec
-# Where to put the Info files.
-infodir = $(datarootdir)/info
-@end smallexample
-
-If your program installs a large number of files into one of the
-standard user-specified directories, it might be useful to group them
-into a subdirectory particular to that program.  If you do this, you
-should write the @code{install} rule to create these subdirectories.
-
-Do not expect the user to include the subdirectory name in the value of
-any of the variables listed above.  The idea of having a uniform set of
-variable names for installation directories is to enable the user to
-specify the exact same values for several different GNU packages.  In
-order for this to be useful, all the packages must be designed so that
-they will work sensibly when the user does so.
-
-At times, not all of these variables may be implemented in the current
-release of Autoconf and/or Automake; but as of Autoconf@tie{}2.60, we
-believe all of them are.  When any are missing, the descriptions here
-serve as specifications for what Autoconf will implement.  As a
-programmer, you can either use a development version of Autoconf or
-avoid using these variables until a stable release is made which
-supports them.
-
-
-@node Standard Targets
-@section Standard Targets for Users
-
-All GNU programs should have the following targets in their Makefiles:
-
-@table @samp
-@item all
-Compile the entire program.  This should be the default target.  This
-target need not rebuild any documentation files; Info files should
-normally be included in the distribution, and DVI (and other
-documentation format) files should be made only when explicitly asked
-for.
-
-By default, the Make rules should compile and link with @samp{-g}, so
-that executable programs have debugging symbols.  Otherwise, you are
-essentially helpless in the face of a crash, and it is often far from
-easy to reproduce with a fresh build.
-
-@item install
-Compile the program and copy the executables, libraries, and so on to
-the file names where they should reside for actual use.  If there is a
-simple test to verify that a program is properly installed, this target
-should run that test.
-
-Do not strip executables when installing them.  This helps eventual
-debugging that may be needed later, and nowadays disk space is cheap
-and dynamic loaders typically ensure debug sections are not loaded during
-normal execution.  Users that need stripped binaries may invoke the
-@code{install-strip} target to do that.
-
-If possible, write the @code{install} target rule so that it does not
-modify anything in the directory where the program was built, provided
-@samp{make all} has just been done.  This is convenient for building the
-program under one user name and installing it under another.
-
-The commands should create all the directories in which files are to be
-installed, if they don't already exist.  This includes the directories
-specified as the values of the variables @code{prefix} and
-@code{exec_prefix}, as well as all subdirectories that are needed.
-One way to do this is by means of an @code{installdirs} target
-as described below.
-
-Use @samp{-} before any command for installing a man page, so that
-@code{make} will ignore any errors.  This is in case there are systems
-that don't have the Unix man page documentation system installed.
-
-The way to install Info files is to copy them into @file{$(infodir)}
-with @code{$(INSTALL_DATA)} (@pxref{Command Variables}), and then run
-the @code{install-info} program if it is present.  @code{install-info}
-is a program that edits the Info @file{dir} file to add or update the
-menu entry for the given Info file; it is part of the Texinfo package.
-
-Here is a sample rule to install an Info file that also tries to
-handle some additional situations, such as @code{install-info} not
-being present.
-
-@comment This example has been carefully formatted for the Make manual.
-@comment Please do not reformat it without talking to bug-make@gnu.org.
-@smallexample
-do-install-info: foo.info installdirs
-        $(NORMAL_INSTALL)
-# Prefer an info file in . to one in srcdir.
-        if test -f foo.info; then d=.; \
-         else d="$(srcdir)"; fi; \
-        $(INSTALL_DATA) $$d/foo.info \
-          "$(DESTDIR)$(infodir)/foo.info"
-# Run install-info only if it exists.
-# Use 'if' instead of just prepending '-' to the
-# line so we notice real errors from install-info.
-# Use '$(SHELL) -c' because some shells do not
-# fail gracefully when there is an unknown command.
-        $(POST_INSTALL)
-        if $(SHELL) -c 'install-info --version' \
-           >/dev/null 2>&1; then \
-          install-info --dir-file="$(DESTDIR)$(infodir)/dir" \
-                       "$(DESTDIR)$(infodir)/foo.info"; \
-        else true; fi
-@end smallexample
-
-When writing the @code{install} target, you must classify all the
-commands into three categories: normal ones, @dfn{pre-installation}
-commands and @dfn{post-installation} commands.  @xref{Install Command
-Categories}.
-
-@item install-html
-@itemx install-dvi
-@itemx install-pdf
-@itemx install-ps
-These targets install documentation in formats other than Info;
-they're intended to be called explicitly by the person installing the
-package, if that format is desired.  GNU prefers Info files, so these
-must be installed by the @code{install} target.
-
-When you have many documentation files to install, we recommend that
-you avoid collisions and clutter by arranging for these targets to
-install in subdirectories of the appropriate installation directory,
-such as @code{htmldir}.  As one example, if your package has multiple
-manuals, and you wish to install HTML documentation with many files
-(such as the ``split'' mode output by @code{makeinfo --html}), you'll
-certainly want to use subdirectories, or two nodes with the same name
-in different manuals will overwrite each other.
-
-Please make these @code{install-@var{format}} targets invoke the
-commands for the @var{format} target, for example, by making
-@var{format} a dependency.
-
-@item uninstall
-Delete all the installed files---the copies that the @samp{install}
-and @samp{install-*} targets create.
-
-This rule should not modify the directories where compilation is done,
-only the directories where files are installed.
-
-The uninstallation commands are divided into three categories, just like
-the installation commands.  @xref{Install Command Categories}.
-
-@item install-strip
-Like @code{install}, but strip the executable files while installing
-them.  In simple cases, this target can use the @code{install} target in
-a simple way:
-
-@smallexample
-install-strip:
-        $(MAKE) INSTALL_PROGRAM='$(INSTALL_PROGRAM) -s' \
-                install
-@end smallexample
-
-But if the package installs scripts as well as real executables, the
-@code{install-strip} target can't just refer to the @code{install}
-target; it has to strip the executables but not the scripts.
-
-@code{install-strip} should not strip the executables in the build
-directory which are being copied for installation.  It should only strip
-the copies that are installed.
-
-Normally we do not recommend stripping an executable unless you are sure
-the program has no bugs.  However, it can be reasonable to install a
-stripped executable for actual execution while saving the unstripped
-executable elsewhere in case there is a bug.
-
-@item clean
-Delete all files in the current directory that are normally created by
-building the program.  Also delete files in other directories if they
-are created by this makefile.  However, don't delete the files that
-record the configuration.  Also preserve files that could be made by
-building, but normally aren't because the distribution comes with
-them.  There is no need to delete parent directories that were created
-with @samp{mkdir -p}, since they could have existed anyway.
-
-Delete @file{.dvi} files here if they are not part of the distribution.
-
-@item distclean
-Delete all files in the current directory (or created by this
-makefile) that are created by configuring or building the program.  If
-you have unpacked the source and built the program without creating
-any other files, @samp{make distclean} should leave only the files
-that were in the distribution.  However, there is no need to delete
-parent directories that were created with @samp{mkdir -p}, since they
-could have existed anyway.
-
-@item mostlyclean
-Like @samp{clean}, but may refrain from deleting a few files that people
-normally don't want to recompile.  For example, the @samp{mostlyclean}
-target for GCC does not delete @file{libgcc.a}, because recompiling it
-is rarely necessary and takes a lot of time.
-
-@item maintainer-clean
-Delete almost everything that can be reconstructed with this Makefile.
-This typically includes everything deleted by @code{distclean}, plus
-more: C source files produced by Bison, tags tables, Info files, and
-so on.
-
-The reason we say ``almost everything'' is that running the command
-@samp{make maintainer-clean} should not delete @file{configure} even
-if @file{configure} can be remade using a rule in the Makefile.  More
-generally, @samp{make maintainer-clean} should not delete anything
-that needs to exist in order to run @file{configure} and then begin to
-build the program.  Also, there is no need to delete parent
-directories that were created with @samp{mkdir -p}, since they could
-have existed anyway.  These are the only exceptions;
-@code{maintainer-clean} should delete everything else that can be
-rebuilt.
-
-The @samp{maintainer-clean} target is intended to be used by a maintainer of
-the package, not by ordinary users.  You may need special tools to
-reconstruct some of the files that @samp{make maintainer-clean} deletes.
-Since these files are normally included in the distribution, we don't
-take care to make them easy to reconstruct.  If you find you need to
-unpack the full distribution again, don't blame us.
-
-To help make users aware of this, the commands for the special
-@code{maintainer-clean} target should start with these two:
-
-@smallexample
-@@echo 'This command is intended for maintainers to use; it'
-@@echo 'deletes files that may need special tools to rebuild.'
-@end smallexample
-
-@item TAGS
-Update a tags table for this program.
-@c ADR: how?
-
-@item info
-Generate any Info files needed.  The best way to write the rules is as
-follows:
-
-@smallexample
-info: foo.info
-
-foo.info: foo.texi chap1.texi chap2.texi
-        $(MAKEINFO) $(srcdir)/foo.texi
-@end smallexample
-
-@noindent
-You must define the variable @code{MAKEINFO} in the Makefile.  It should
-run the @code{makeinfo} program, which is part of the Texinfo
-distribution.
-
-Normally a GNU distribution comes with Info files, and that means the
-Info files are present in the source directory.  Therefore, the Make
-rule for an info file should update it in the source directory.  When
-users build the package, ordinarily Make will not update the Info files
-because they will already be up to date.
-
-@item dvi
-@itemx html
-@itemx pdf
-@itemx ps
-Generate documentation files in the given format.  These targets
-should always exist, but any or all can be a no-op if the given output
-format cannot be generated.  These targets should not be dependencies
-of the @code{all} target; the user must manually invoke them.
-
-Here's an example rule for generating DVI files from Texinfo:
-
-@smallexample
-dvi: foo.dvi
-
-foo.dvi: foo.texi chap1.texi chap2.texi
-        $(TEXI2DVI) $(srcdir)/foo.texi
-@end smallexample
-
-@noindent
-You must define the variable @code{TEXI2DVI} in the Makefile.  It
-should run the program @code{texi2dvi}, which is part of the Texinfo
-distribution.  (@code{texi2dvi} uses @TeX{} to do the real work of
-formatting. @TeX{} is not distributed with Texinfo.)  Alternatively,
-write only the dependencies, and allow GNU @code{make} to provide the
-command.
-
-Here's another example, this one for generating HTML from Texinfo:
-
-@smallexample
-html: foo.html
-
-foo.html: foo.texi chap1.texi chap2.texi
-        $(TEXI2HTML) $(srcdir)/foo.texi
-@end smallexample
-
-@noindent
-Again, you would define the variable @code{TEXI2HTML} in the Makefile;
-for example, it might run @code{makeinfo --no-split --html}
-(@command{makeinfo} is part of the Texinfo distribution).
-
-@item dist
-Create a distribution tar file for this program.  The tar file should be
-set up so that the file names in the tar file start with a subdirectory
-name which is the name of the package it is a distribution for.  This
-name can include the version number.
-
-For example, the distribution tar file of GCC version 1.40 unpacks into
-a subdirectory named @file{gcc-1.40}.
-
-The easiest way to do this is to create a subdirectory appropriately
-named, use @code{ln} or @code{cp} to install the proper files in it, and
-then @code{tar} that subdirectory.
-
-Compress the tar file with @code{gzip}.  For example, the actual
-distribution file for GCC version 1.40 is called @file{gcc-1.40.tar.gz}.
-It is ok to support other free compression formats as well.
-
-The @code{dist} target should explicitly depend on all non-source files
-that are in the distribution, to make sure they are up to date in the
-distribution.
-@ifset CODESTD
-@xref{Releases, , Making Releases}.
-@end ifset
-@ifclear CODESTD
-@xref{Releases, , Making Releases, standards, GNU Coding Standards}.
-@end ifclear
-
-@item check
-Perform self-tests (if any).  The user must build the program before
-running the tests, but need not install the program; you should write
-the self-tests so that they work when the program is built but not
-installed.
-@end table
-
-The following targets are suggested as conventional names, for programs
-in which they are useful.
-
-@table @code
-@item installcheck
-Perform installation tests (if any).  The user must build and install
-the program before running the tests.  You should not assume that
-@file{$(bindir)} is in the search path.
-
-@item installdirs
-It's useful to add a target named @samp{installdirs} to create the
-directories where files are installed, and their parent directories.
-There is a script called @file{mkinstalldirs} which is convenient for
-this; you can find it in the Gnulib package.
-You can use a rule like this:
-
-@comment This has been carefully formatted to look decent in the Make manual.
-@comment Please be sure not to make it extend any further to the right.--roland
-@smallexample
-# Make sure all installation directories (e.g. $(bindir))
-# actually exist by making them if necessary.
-installdirs: mkinstalldirs
-        $(srcdir)/mkinstalldirs $(bindir) $(datadir) \
-                                $(libdir) $(infodir) \
-                                $(mandir)
-@end smallexample
-
-@noindent
-or, if you wish to support @env{DESTDIR} (strongly encouraged),
-
-@smallexample
-# Make sure all installation directories (e.g. $(bindir))
-# actually exist by making them if necessary.
-installdirs: mkinstalldirs
-        $(srcdir)/mkinstalldirs \
-            $(DESTDIR)$(bindir) $(DESTDIR)$(datadir) \
-            $(DESTDIR)$(libdir) $(DESTDIR)$(infodir) \
-            $(DESTDIR)$(mandir)
-@end smallexample
-
-This rule should not modify the directories where compilation is done.
-It should do nothing but create installation directories.
-@end table
-
-@node Install Command Categories
-@section Install Command Categories
-
-@cindex pre-installation commands
-@cindex post-installation commands
-When writing the @code{install} target, you must classify all the
-commands into three categories: normal ones, @dfn{pre-installation}
-commands and @dfn{post-installation} commands.
-
-Normal commands move files into their proper places, and set their
-modes.  They may not alter any files except the ones that come entirely
-from the package they belong to.
-
-Pre-installation and post-installation commands may alter other files;
-in particular, they can edit global configuration files or data bases.
-
-Pre-installation commands are typically executed before the normal
-commands, and post-installation commands are typically run after the
-normal commands.
-
-The most common use for a post-installation command is to run
-@code{install-info}.  This cannot be done with a normal command, since
-it alters a file (the Info directory) which does not come entirely and
-solely from the package being installed.  It is a post-installation
-command because it needs to be done after the normal command which
-installs the package's Info files.
-
-Most programs don't need any pre-installation commands, but we have the
-feature just in case it is needed.
-
-To classify the commands in the @code{install} rule into these three
-categories, insert @dfn{category lines} among them.  A category line
-specifies the category for the commands that follow.
-
-A category line consists of a tab and a reference to a special Make
-variable, plus an optional comment at the end.  There are three
-variables you can use, one for each category; the variable name
-specifies the category.  Category lines are no-ops in ordinary execution
-because these three Make variables are normally undefined (and you
-@emph{should not} define them in the makefile).
-
-Here are the three possible category lines, each with a comment that
-explains what it means:
-
-@smallexample
-        $(PRE_INSTALL)     # @r{Pre-install commands follow.}
-        $(POST_INSTALL)    # @r{Post-install commands follow.}
-        $(NORMAL_INSTALL)  # @r{Normal commands follow.}
-@end smallexample
-
-If you don't use a category line at the beginning of the @code{install}
-rule, all the commands are classified as normal until the first category
-line.  If you don't use any category lines, all the commands are
-classified as normal.
-
-These are the category lines for @code{uninstall}:
-
-@smallexample
-        $(PRE_UNINSTALL)     # @r{Pre-uninstall commands follow.}
-        $(POST_UNINSTALL)    # @r{Post-uninstall commands follow.}
-        $(NORMAL_UNINSTALL)  # @r{Normal commands follow.}
-@end smallexample
-
-Typically, a pre-uninstall command would be used for deleting entries
-from the Info directory.
-
-If the @code{install} or @code{uninstall} target has any dependencies
-which act as subroutines of installation, then you should start
-@emph{each} dependency's commands with a category line, and start the
-main target's commands with a category line also.  This way, you can
-ensure that each command is placed in the right category regardless of
-which of the dependencies actually run.
-
-Pre-installation and post-installation commands should not run any
-programs except for these:
-
-@example
-[ basename bash cat chgrp chmod chown cmp cp dd diff echo
-egrep expand expr false fgrep find getopt grep gunzip gzip
-hostname install install-info kill ldconfig ln ls md5sum
-mkdir mkfifo mknod mv printenv pwd rm rmdir sed sort tee
-test touch true uname xargs yes
-@end example
-
-@cindex binary packages
-The reason for distinguishing the commands in this way is for the sake
-of making binary packages.  Typically a binary package contains all the
-executables and other files that need to be installed, and has its own
-method of installing them---so it does not need to run the normal
-installation commands.  But installing the binary package does need to
-execute the pre-installation and post-installation commands.
-
-Programs to build binary packages work by extracting the
-pre-installation and post-installation commands.  Here is one way of
-extracting the pre-installation commands (the @option{-s} option to
-@command{make} is needed to silence messages about entering
-subdirectories):
-
-@smallexample
-make -s -n install -o all \
-      PRE_INSTALL=pre-install \
-      POST_INSTALL=post-install \
-      NORMAL_INSTALL=normal-install \
-  | gawk -f pre-install.awk
-@end smallexample
-
-@noindent
-where the file @file{pre-install.awk} could contain this:
-
-@smallexample
-$0 ~ /^(normal-install|post-install)[ \t]*$/ @{on = 0@}
-on @{print $0@}
-$0 ~ /^pre-install[ \t]*$/ @{on = 1@}
-@end smallexample

-.TH MAKE 1 "28 February 2016" "GNU" "User Commands"
-.SH NAME
-make \- GNU make utility to maintain groups of programs
-.SH SYNOPSIS
-.B make
-[\fIOPTION\fR]... [\fITARGET\fR]...
-.SH DESCRIPTION
-.LP
-The
-.I make
-utility will determine automatically which pieces of a large program need to
-be recompiled, and issue the commands to recompile them.  The manual describes
-the GNU implementation of
-.BR make ,
-which was written by Richard Stallman and Roland McGrath, and is currently
-maintained by Paul Smith.  Our examples show C programs, since they are very
-common, but you can use
-.B make
-with any programming language whose compiler can be run with a shell command.
-In fact,
-.B make
-is not limited to programs.  You can use it to describe any task where some
-files must be updated automatically from others whenever the others change.
-.LP
-To prepare to use
-.BR make ,
-you must write a file called the
-.I makefile
-that describes the relationships among files in your program, and the states
-the commands for updating each file.  In a program, typically the executable
-file is updated from object files, which are in turn made by compiling source
-files.
-.LP
-Once a suitable makefile exists, each time you change some source files,
-this simple shell command:
-.sp 1
-.RS
-.B make
-.RE
-.sp 1
-suffices to perform all necessary recompilations.
-The
-.B make
-program uses the makefile description and the last-modification times of the
-files to decide which of the files need to be updated.  For each of those
-files, it issues the commands recorded in the makefile.
-.LP
-.B make
-executes commands in the
-.I makefile
-to update one or more target
-.IR names ,
-where
-.I name
-is typically a program.
-If no
-.B \-f
-option is present,
-.B make
-will look for the makefiles
-.IR GNUmakefile ,
-.IR makefile ,
-and
-.IR Makefile ,
-in that order.
-.LP
-Normally you should call your makefile either
-.I makefile
-or
-.IR Makefile .
-(We recommend
-.I Makefile
-because it appears prominently near the beginning of a directory
-listing, right near other important files such as
-.IR  README .)
-The first name checked,
-.IR GNUmakefile ,
-is not recommended for most makefiles.  You should use this name if you have a
-makefile that is specific to GNU
-.BR make ,
-and will not be understood by other versions of
-.BR make .
-If
-.I makefile
-is '\-', the standard input is read.
-.LP
-.B make
-updates a target if it depends on prerequisite files
-that have been modified since the target was last modified,
-or if the target does not exist.
-.SH OPTIONS
-.sp 1
-.TP 0.5i
-\fB\-b\fR, \fB\-m\fR
-These options are ignored for compatibility with other versions of
-.BR make .
-.TP 0.5i
-\fB\-B\fR, \fB\-\-always\-make\fR
-Unconditionally make all targets.
-.TP 0.5i
-\fB\-C\fR \fIdir\fR, \fB\-\-directory\fR=\fIdir\fR
-Change to directory
-.I dir
-before reading the makefiles or doing anything else.
-If multiple
-.B \-C
-options are specified, each is interpreted relative to the
-previous one:
-.BR "\-C " /
-.BR "\-C " etc
-is equivalent to
-.BR "\-C " /etc.
-This is typically used with recursive invocations of
-.BR make .
-.TP 0.5i
-.B \-d
-Print debugging information in addition to normal processing.
-The debugging information says which files are being considered for
-remaking, which file-times are being compared and with what results,
-which files actually need to be remade, which implicit rules are
-considered and which are applied---everything interesting about how
-.B make
-decides what to do.
-.TP 0.5i
-.BI \-\-debug "[=FLAGS]"
-Print debugging information in addition to normal processing.
-If the
-.I FLAGS
-are omitted, then the behavior is the same as if
-.B \-d
-was specified.
-.I FLAGS
-may be
-.I a
-for all debugging output (same as using
-.BR \-d ),
-.I b
-for basic debugging,
-.I v
-for more verbose basic debugging,
-.I i
-for showing implicit rules,
-.I j
-for details on invocation of commands, and
-.I m
-for debugging while remaking makefiles.  Use
-.I n
-to disable all previous debugging flags.
-.TP 0.5i
-\fB\-e\fR, \fB\-\-environment\-overrides\fR
-Give variables taken from the environment precedence over variables
-from makefiles.
-.TP 0.5i
-\fB\-E\fR \fIstring\fR, \fB\-\-eval\fR \fIstring\fR
-Interpret \fIstring\fR using the \fBeval\fR function, before parsing any
-makefiles.
-.TP 0.5i
-\fB\-f\fR \fIfile\fR, \fB\-\-file\fR=\fIfile\fR, \fB\-\-makefile\fR=\fIFILE\fR
-Use
-.I file
-as a makefile.
-.TP 0.5i
-\fB\-i\fR, \fB\-\-ignore\-errors\fR
-Ignore all errors in commands executed to remake files.
-.TP 0.5i
-\fB\-I\fR \fIdir\fR, \fB\-\-include\-dir\fR=\fIdir\fR
-Specifies a directory
-.I dir
-to search for included makefiles.
-If several
-.B \-I
-options are used to specify several directories, the directories are
-searched in the order specified.
-Unlike the arguments to other flags of
-.BR make ,
-directories given with
-.B \-I
-flags may come directly after the flag:
-.BI \-I dir
-is allowed, as well as
-.B \-I
-.IR dir .
-This syntax is allowed for compatibility with the C
-preprocessor's
-.B \-I
-flag.
-.TP 0.5i
-\fB\-j\fR [\fIjobs\fR], \fB\-\-jobs\fR[=\fIjobs\fR]
-Specifies the number of
-.I jobs
-(commands) to run simultaneously.
-If there is more than one
-.B \-j
-option, the last one is effective.
-If the
-.B \-j
-option is given without an argument,
-.BR make
-will not limit the number of jobs that can run simultaneously.
-.TP 0.5i
-\fB\-k\fR, \fB\-\-keep\-going\fR
-Continue as much as possible after an error.
-While the target that failed, and those that depend on it, cannot
-be remade, the other dependencies of these targets can be processed
-all the same.
-.TP 0.5i
-\fB\-l\fR [\fIload\fR], \fB\-\-load\-average\fR[=\fIload\fR]
-Specifies that no new jobs (commands) should be started if there are
-others jobs running and the load average is at least
-.I load
-(a floating-point number).
-With no argument, removes a previous load limit.
-.TP 0.5i
-\fB\-L\fR, \fB\-\-check\-symlink\-times\fR
-Use the latest mtime between symlinks and target.
-.TP 0.5i
-\fB\-n\fR, \fB\-\-just\-print\fR, \fB\-\-dry\-run\fR, \fB\-\-recon\fR
-Print the commands that would be executed, but do not execute them (except in
-certain circumstances).
-.TP 0.5i
-\fB\-o\fR \fIfile\fR, \fB\-\-old\-file\fR=\fIfile\fR, \fB\-\-assume\-old\fR=\fIfile\fR
-Do not remake the file
-.I file
-even if it is older than its dependencies, and do not remake anything
-on account of changes in
-.IR file .
-Essentially the file is treated as very old and its rules are ignored.
-.TP 0.5i
-\fB\-O\fR[\fItype\fR], \fB\-\-output\-sync\fR[=\fItype\fR]
-When running multiple jobs in parallel with \fB-j\fR, ensure the output of
-each job is collected together rather than interspersed with output from
-other jobs.  If
-.I type
-is not specified or is
-.B target
-the output from the entire recipe for each target is grouped together.  If
-.I type
-is
-.B line
-the output from each command line within a recipe is grouped together.
-If
-.I type
-is
-.B recurse
-output from an entire recursive make is grouped together.  If
-.I type
-is
-.B none
-output synchronization is disabled.
-.TP 0.5i
-\fB\-p\fR, \fB\-\-print\-data\-base\fR
-Print the data base (rules and variable values) that results from
-reading the makefiles; then execute as usual or as otherwise
-specified.
-This also prints the version information given by the
-.B \-v
-switch (see below).
-To print the data base without trying to remake any files, use
-.IR "make \-p \-f/dev/null" .
-.TP 0.5i
-\fB\-q\fR, \fB\-\-question\fR
-``Question mode''.
-Do not run any commands, or print anything; just return an exit status
-that is zero if the specified targets are already up to date, nonzero
-otherwise.
-.TP 0.5i
-\fB\-r\fR, \fB\-\-no\-builtin\-rules\fR
-Eliminate use of the built\-in implicit rules.
-Also clear out the default list of suffixes for suffix rules.
-.TP 0.5i
-\fB\-R\fR, \fB\-\-no\-builtin\-variables\fR
-Don't define any built\-in variables.
-.TP 0.5i
-\fB\-s\fR, \fB\-\-silent\fR, \fB\-\-quiet\fR
-Silent operation; do not print the commands as they are executed.
-.TP 0.5i
-.B \-\-no\-silent
-Cancel the effect of the \fB\-s\fR option.
-.TP 0.5i
-\fB\-S\fR, \fB\-\-no\-keep\-going\fR, \fB\-\-stop\fR
-Cancel the effect of the
-.B \-k
-option.
-.TP 0.5i
-\fB\-t\fR, \fB\-\-touch\fR
-Touch files (mark them up to date without really changing them)
-instead of running their commands.
-This is used to pretend that the commands were done, in order to fool
-future invocations of
-.BR make .
-.TP 0.5i
-.B \-\-trace
-Information about the disposition of each target is printed (why the target is
-being rebuilt and what commands are run to rebuild it).
-.TP 0.5i
-\fB\-v\fR, \fB\-\-version\fR
-Print the version of the
-.B make
-program plus a copyright, a list of authors and a notice that there
-is no warranty.
-.TP 0.5i
-\fB\-w\fR, \fB\-\-print\-directory\fR
-Print a message containing the working directory
-before and after other processing.
-This may be useful for tracking down errors from complicated nests of
-recursive
-.B make
-commands.
-.TP 0.5i
-.B \-\-no\-print\-directory
-Turn off
-.BR \-w ,
-even if it was turned on implicitly.
-.TP 0.5i
-\fB\-W\fR \fIfile\fR, \fB\-\-what\-if\fR=\fIfile\fR, \fB\-\-new\-file\fR=\fIfile\fR, \fB\-\-assume\-new\fR=\fIfile\fR
-Pretend that the target
-.I file
-has just been modified.
-When used with the
-.B \-n
-flag, this shows you what would happen if you were to modify that file.
-Without
-.BR \-n ,
-it is almost the same as running a
-.I touch
-command on the given file before running
-.BR make ,
-except that the modification time is changed only in the imagination of
-.BR make .
-.TP 0.5i
-.B \-\-warn\-undefined\-variables
-Warn when an undefined variable is referenced.
-.SH "EXIT STATUS"
-GNU
-.B make
-exits with a status of zero if all makefiles were successfully parsed
-and no targets that were built failed.  A status of one will be returned
-if the
-.B \-q
-flag was used and
-.B make
-determines that a target needs to be rebuilt.  A status of two will be
-returned if any errors were encountered.
-.SH "SEE ALSO"
-The full documentation for
-.B make
-is maintained as a Texinfo manual.  If the
-.B info
-and
-.B make
-programs are properly installed at your site, the command
-.IP
-.B info make
-.PP
-should give you access to the complete manual.

-1 Overview of 'make'
-********************
-
-The 'make' utility automatically determines which pieces of a large
-program need to be recompiled, and issues commands to recompile them.
-This manual describes GNU 'make', which was implemented by Richard
-Stallman and Roland McGrath.  Development since Version 3.76 has been
-handled by Paul D. Smith.
-
-   GNU 'make' conforms to section 6.2 of 'IEEE Standard 1003.2-1992'
-(POSIX.2).
-
-   Our examples show C programs, since they are most common, but you can
-use 'make' with any programming language whose compiler can be run with
-a shell command.  Indeed, 'make' is not limited to programs.  You can
-use it to describe any task where some files must be updated
-automatically from others whenever the others change.

-
-Preparing and Running Make
-==========================
-
-To prepare to use 'make', you must write a file called the "makefile"
-that describes the relationships among files in your program and
-provides commands for updating each file.  In a program, typically, the
-executable file is updated from object files, which are in turn made by
-compiling source files.
-
-   Once a suitable makefile exists, each time you change some source
-files, this simple shell command:
-
-     make
-
-suffices to perform all necessary recompilations.  The 'make' program
-uses the makefile data base and the last-modification times of the files
-to decide which of the files need to be updated.  For each of those
-files, it issues the recipes recorded in the data base.
-
-   You can provide command line arguments to 'make' to control which
-files should be recompiled, or how.  *Note How to Run 'make': Running.

-1.1 How to Read This Manual
-===========================
-
-If you are new to 'make', or are looking for a general introduction,
-read the first few sections of each chapter, skipping the later
-sections.  In each chapter, the first few sections contain introductory
-or general information and the later sections contain specialized or
-technical information.  The exception is the second chapter, *note An
-Introduction to Makefiles: Introduction, all of which is introductory.
-
-   If you are familiar with other 'make' programs, see *note Features of
-GNU 'make': Features, which lists the enhancements GNU 'make' has, and
-*note Incompatibilities and Missing Features: Missing, which explains
-the few things GNU 'make' lacks that others have.

-1.2 Problems and Bugs
-=====================
-
-If you have problems with GNU 'make' or think you've found a bug, please
-report it to the developers; we cannot promise to do anything but we
-might well want to fix it.
-
-   Before reporting a bug, make sure you've actually found a real bug.
-Carefully reread the documentation and see if it really says you can do
-what you're trying to do.  If it's not clear whether you should be able
-to do something or not, report that too; it's a bug in the
-documentation!
-
-   Before reporting a bug or trying to fix it yourself, try to isolate
-it to the smallest possible makefile that reproduces the problem.  Then
-send us the makefile and the exact results 'make' gave you, including
-any error or warning messages.  Please don't paraphrase these messages:
-it's best to cut and paste them into your report.  When generating this
-small makefile, be sure to not use any non-free or unusual tools in your
-recipes: you can almost always emulate what such a tool would do with
-simple shell commands.  Finally, be sure to explain what you expected to
-occur; this will help us decide whether the problem was really in the
-documentation.
-
-   Once you have a precise problem you can report it in one of two ways.
-Either send electronic mail to:
-
-         bug-make@gnu.org
-
-or use our Web-based project management tool, at:
-
-         http://savannah.gnu.org/projects/make/
-
-In addition to the information above, please be careful to include the
-version number of 'make' you are using.  You can get this information
-with the command 'make --version'.  Be sure also to include the type of
-machine and operating system you are using.  One way to obtain this
-information is by looking at the final lines of output from the command
-'make --help'.

-
-2 An Introduction to Makefiles
-******************************
-
-You need a file called a "makefile" to tell 'make' what to do.  Most
-often, the makefile tells 'make' how to compile and link a program.
-
-   In this chapter, we will discuss a simple makefile that describes how
-to compile and link a text editor which consists of eight C source files
-and three header files.  The makefile can also tell 'make' how to run
-miscellaneous commands when explicitly asked (for example, to remove
-certain files as a clean-up operation).  To see a more complex example
-of a makefile, see *note Complex Makefile::.
-
-   When 'make' recompiles the editor, each changed C source file must be
-recompiled.  If a header file has changed, each C source file that
-includes the header file must be recompiled to be safe.  Each
-compilation produces an object file corresponding to the source file.
-Finally, if any source file has been recompiled, all the object files,
-whether newly made or saved from previous compilations, must be linked
-together to produce the new executable editor.

-
-2.1 What a Rule Looks Like
-==========================
-
-A simple makefile consists of "rules" with the following shape:
-
-     TARGET ... : PREREQUISITES ...
-             RECIPE
-             ...
-             ...
-
-   A "target" is usually the name of a file that is generated by a
-program; examples of targets are executable or object files.  A target
-can also be the name of an action to carry out, such as 'clean' (*note
-Phony Targets::).
-
-   A "prerequisite" is a file that is used as input to create the
-target.  A target often depends on several files.
-
-   A "recipe" is an action that 'make' carries out.  A recipe may have
-more than one command, either on the same line or each on its own line.
-*Please note:* you need to put a tab character at the beginning of every
-recipe line!  This is an obscurity that catches the unwary.  If you
-prefer to prefix your recipes with a character other than tab, you can
-set the '.RECIPEPREFIX' variable to an alternate character (*note
-Special Variables::).
-
-   Usually a recipe is in a rule with prerequisites and serves to create
-a target file if any of the prerequisites change.  However, the rule
-that specifies a recipe for the target need not have prerequisites.  For
-example, the rule containing the delete command associated with the
-target 'clean' does not have prerequisites.
-
-   A "rule", then, explains how and when to remake certain files which
-are the targets of the particular rule.  'make' carries out the recipe
-on the prerequisites to create or update the target.  A rule can also
-explain how and when to carry out an action.  *Note Writing Rules:
-Rules.
-
-   A makefile may contain other text besides rules, but a simple
-makefile need only contain rules.  Rules may look somewhat more
-complicated than shown in this template, but all fit the pattern more or
-less.
-

-
-2.2 A Simple Makefile
-=====================
-
-Here is a straightforward makefile that describes the way an executable
-file called 'edit' depends on eight object files which, in turn, depend
-on eight C source and three header files.
-
-   In this example, all the C files include 'defs.h', but only those
-defining editing commands include 'command.h', and only low level files
-that change the editor buffer include 'buffer.h'.
-
-     edit : main.o kbd.o command.o display.o \
-            insert.o search.o files.o utils.o
-             cc -o edit main.o kbd.o command.o display.o \
-                        insert.o search.o files.o utils.o
-
-     main.o : main.c defs.h
-             cc -c main.c
-     kbd.o : kbd.c defs.h command.h
-             cc -c kbd.c
-     command.o : command.c defs.h command.h
-             cc -c command.c
-     display.o : display.c defs.h buffer.h
-             cc -c display.c
-     insert.o : insert.c defs.h buffer.h
-             cc -c insert.c
-     search.o : search.c defs.h buffer.h
-             cc -c search.c
-     files.o : files.c defs.h buffer.h command.h
-             cc -c files.c
-     utils.o : utils.c defs.h
-             cc -c utils.c
-     clean :
-             rm edit main.o kbd.o command.o display.o \
-                insert.o search.o files.o utils.o
-
-We split each long line into two lines using backslash/newline; this is
-like using one long line, but is easier to read.  *Note Splitting Long
-Lines: Splitting Lines.
-
-   To use this makefile to create the executable file called 'edit',
-type:
-
-     make
-
-   To use this makefile to delete the executable file and all the object
-files from the directory, type:
-
-     make clean
-
-   In the example makefile, the targets include the executable file
-'edit', and the object files 'main.o' and 'kbd.o'.  The prerequisites
-are files such as 'main.c' and 'defs.h'.  In fact, each '.o' file is
-both a target and a prerequisite.  Recipes include 'cc -c main.c' and
-'cc -c kbd.c'.
-
-   When a target is a file, it needs to be recompiled or relinked if any
-of its prerequisites change.  In addition, any prerequisites that are
-themselves automatically generated should be updated first.  In this
-example, 'edit' depends on each of the eight object files; the object
-file 'main.o' depends on the source file 'main.c' and on the header file
-'defs.h'.
-
-   A recipe may follow each line that contains a target and
-prerequisites.  These recipes say how to update the target file.  A tab
-character (or whatever character is specified by the '.RECIPEPREFIX'
-variable; *note Special Variables::) must come at the beginning of every
-line in the recipe to distinguish recipes from other lines in the
-makefile.  (Bear in mind that 'make' does not know anything about how
-the recipes work.  It is up to you to supply recipes that will update
-the target file properly.  All 'make' does is execute the recipe you
-have specified when the target file needs to be updated.)
-
-   The target 'clean' is not a file, but merely the name of an action.
-Since you normally do not want to carry out the actions in this rule,
-'clean' is not a prerequisite of any other rule.  Consequently, 'make'
-never does anything with it unless you tell it specifically.  Note that
-this rule not only is not a prerequisite, it also does not have any
-prerequisites, so the only purpose of the rule is to run the specified
-recipe.  Targets that do not refer to files but are just actions are
-called "phony targets".  *Note Phony Targets::, for information about
-this kind of target.  *Note Errors in Recipes: Errors, to see how to
-cause 'make' to ignore errors from 'rm' or any other command.
-
-
-File: make.info,  Node: How Make Works,  Next: Variables Simplify,  Prev: Simple Makefile,  Up: Introduction
-
-2.3 How 'make' Processes a Makefile
-===================================
-
-By default, 'make' starts with the first target (not targets whose names
-start with '.').  This is called the "default goal".  ("Goals" are the
-targets that 'make' strives ultimately to update.  You can override this
-behavior using the command line (*note Arguments to Specify the Goals:
-Goals.) or with the '.DEFAULT_GOAL' special variable (*note Other
-Special Variables: Special Variables.).
-
-   In the simple example of the previous section, the default goal is to
-update the executable program 'edit'; therefore, we put that rule first.
-
-   Thus, when you give the command:
-
-     make
-
-'make' reads the makefile in the current directory and begins by
-processing the first rule.  In the example, this rule is for relinking
-'edit'; but before 'make' can fully process this rule, it must process
-the rules for the files that 'edit' depends on, which in this case are
-the object files.  Each of these files is processed according to its own
-rule.  These rules say to update each '.o' file by compiling its source
-file.  The recompilation must be done if the source file, or any of the
-header files named as prerequisites, is more recent than the object
-file, or if the object file does not exist.
-
-   The other rules are processed because their targets appear as
-prerequisites of the goal.  If some other rule is not depended on by the
-goal (or anything it depends on, etc.), that rule is not processed,
-unless you tell 'make' to do so (with a command such as 'make clean').
-
-   Before recompiling an object file, 'make' considers updating its
-prerequisites, the source file and header files.  This makefile does not
-specify anything to be done for them--the '.c' and '.h' files are not
-the targets of any rules--so 'make' does nothing for these files.  But
-'make' would update automatically generated C programs, such as those
-made by Bison or Yacc, by their own rules at this time.
-
-   After recompiling whichever object files need it, 'make' decides
-whether to relink 'edit'.  This must be done if the file 'edit' does not
-exist, or if any of the object files are newer than it.  If an object
-file was just recompiled, it is now newer than 'edit', so 'edit' is
-relinked.
-
-   Thus, if we change the file 'insert.c' and run 'make', 'make' will
-compile that file to update 'insert.o', and then link 'edit'.  If we
-change the file 'command.h' and run 'make', 'make' will recompile the
-object files 'kbd.o', 'command.o' and 'files.o' and then link the file
-'edit'.
-

-
-2.4 Variables Make Makefiles Simpler
-====================================
-
-In our example, we had to list all the object files twice in the rule
-for 'edit' (repeated here):
-
-     edit : main.o kbd.o command.o display.o \
-                   insert.o search.o files.o utils.o
-             cc -o edit main.o kbd.o command.o display.o \
-                        insert.o search.o files.o utils.o
-
-   Such duplication is error-prone; if a new object file is added to the
-system, we might add it to one list and forget the other.  We can
-eliminate the risk and simplify the makefile by using a variable.
-"Variables" allow a text string to be defined once and substituted in
-multiple places later (*note How to Use Variables: Using Variables.).
-
-   It is standard practice for every makefile to have a variable named
-'objects', 'OBJECTS', 'objs', 'OBJS', 'obj', or 'OBJ' which is a list of
-all object file names.  We would define such a variable 'objects' with a
-line like this in the makefile:
-
-     objects = main.o kbd.o command.o display.o \
-               insert.o search.o files.o utils.o
-
-Then, each place we want to put a list of the object file names, we can
-substitute the variable's value by writing '$(objects)' (*note How to
-Use Variables: Using Variables.).
-
-   Here is how the complete simple makefile looks when you use a
-variable for the object files:
-
-     objects = main.o kbd.o command.o display.o \
-               insert.o search.o files.o utils.o
-
-     edit : $(objects)
-             cc -o edit $(objects)
-     main.o : main.c defs.h
-             cc -c main.c
-     kbd.o : kbd.c defs.h command.h
-             cc -c kbd.c
-     command.o : command.c defs.h command.h
-             cc -c command.c
-     display.o : display.c defs.h buffer.h
-             cc -c display.c
-     insert.o : insert.c defs.h buffer.h
-             cc -c insert.c
-     search.o : search.c defs.h buffer.h
-             cc -c search.c
-     files.o : files.c defs.h buffer.h command.h
-             cc -c files.c
-     utils.o : utils.c defs.h
-             cc -c utils.c
-     clean :
-             rm edit $(objects)

-2.5 Letting 'make' Deduce the Recipes
-=====================================
-
-It is not necessary to spell out the recipes for compiling the
-individual C source files, because 'make' can figure them out: it has an
-"implicit rule" for updating a '.o' file from a correspondingly named
-'.c' file using a 'cc -c' command.  For example, it will use the recipe
-'cc -c main.c -o main.o' to compile 'main.c' into 'main.o'.  We can
-therefore omit the recipes from the rules for the object files.  *Note
-Using Implicit Rules: Implicit Rules.
-
-   When a '.c' file is used automatically in this way, it is also
-automatically added to the list of prerequisites.  We can therefore omit
-the '.c' files from the prerequisites, provided we omit the recipe.
-
-   Here is the entire example, with both of these changes, and a
-variable 'objects' as suggested above:
-
-     objects = main.o kbd.o command.o display.o \
-               insert.o search.o files.o utils.o
-
-     edit : $(objects)
-             cc -o edit $(objects)
-
-     main.o : defs.h
-     kbd.o : defs.h command.h
-     command.o : defs.h command.h
-     display.o : defs.h buffer.h
-     insert.o : defs.h buffer.h
-     search.o : defs.h buffer.h
-     files.o : defs.h buffer.h command.h
-     utils.o : defs.h
-
-     .PHONY : clean
-     clean :
-             rm edit $(objects)
-
-This is how we would write the makefile in actual practice.  (The
-complications associated with 'clean' are described elsewhere.  See
-*note Phony Targets::, and *note Errors in Recipes: Errors.)
-
-   Because implicit rules are so convenient, they are important.  You
-will see them used frequently.

-
-2.6 Another Style of Makefile
-=============================
-
-When the objects of a makefile are created only by implicit rules, an
-alternative style of makefile is possible.  In this style of makefile,
-you group entries by their prerequisites instead of by their targets.
-Here is what one looks like:
-
-     objects = main.o kbd.o command.o display.o \
-               insert.o search.o files.o utils.o
-
-     edit : $(objects)
-             cc -o edit $(objects)
-
-     $(objects) : defs.h
-     kbd.o command.o files.o : command.h
-     display.o insert.o search.o files.o : buffer.h
-
-Here 'defs.h' is given as a prerequisite of all the object files;
-'command.h' and 'buffer.h' are prerequisites of the specific object
-files listed for them.
-
-   Whether this is better is a matter of taste: it is more compact, but
-some people dislike it because they find it clearer to put all the
-information about each target in one place.

-2.7 Rules for Cleaning the Directory
-====================================
-
-Compiling a program is not the only thing you might want to write rules
-for.  Makefiles commonly tell how to do a few other things besides
-compiling a program: for example, how to delete all the object files and
-executables so that the directory is 'clean'.
-
-   Here is how we could write a 'make' rule for cleaning our example
-editor:
-
-     clean:
-             rm edit $(objects)
-
-   In practice, we might want to write the rule in a somewhat more
-complicated manner to handle unanticipated situations.  We would do
-this:
-
-     .PHONY : clean
-     clean :
-             -rm edit $(objects)
-
-This prevents 'make' from getting confused by an actual file called
-'clean' and causes it to continue in spite of errors from 'rm'.  (See
-*note Phony Targets::, and *note Errors in Recipes: Errors.)
-
-A rule such as this should not be placed at the beginning of the
-makefile, because we do not want it to run by default!  Thus, in the
-example makefile, we want the rule for 'edit', which recompiles the
-editor, to remain the default goal.
-
-   Since 'clean' is not a prerequisite of 'edit', this rule will not run
-at all if we give the command 'make' with no arguments.  In order to
-make the rule run, we have to type 'make clean'.  *Note How to Run
-'make': Running.

-
-3.1 What Makefiles Contain
-==========================
-
-Makefiles contain five kinds of things: "explicit rules", "implicit
-rules", "variable definitions", "directives", and "comments".  Rules,
-variables, and directives are described at length in later chapters.
-
-   * An "explicit rule" says when and how to remake one or more files,
-     called the rule's "targets".  It lists the other files that the
-     targets depend on, called the "prerequisites" of the target, and
-     may also give a recipe to use to create or update the targets.
-     *Note Writing Rules: Rules.
-
-   * An "implicit rule" says when and how to remake a class of files
-     based on their names.  It describes how a target may depend on a
-     file with a name similar to the target and gives a recipe to create
-     or update such a target.  *Note Using Implicit Rules: Implicit
-     Rules.
-
-   * A "variable definition" is a line that specifies a text string
-     value for a variable that can be substituted into the text later.
-     The simple makefile example shows a variable definition for
-     'objects' as a list of all object files (*note Variables Make
-     Makefiles Simpler: Variables Simplify.).
-
-   * A "directive" is an instruction for 'make' to do something special
-     while reading the makefile.  These include:
-
-        * Reading another makefile (*note Including Other Makefiles:
-          Include.).
-
-        * Deciding (based on the values of variables) whether to use or
-          ignore a part of the makefile (*note Conditional Parts of
-          Makefiles: Conditionals.).
-
-        * Defining a variable from a verbatim string containing multiple
-          lines (*note Defining Multi-Line Variables: Multi-Line.).
-
-   * '#' in a line of a makefile starts a "comment".  It and the rest of
-     the line are ignored, except that a trailing backslash not escaped
-     by another backslash will continue the comment across multiple
-     lines.  A line containing just a comment (with perhaps spaces
-     before it) is effectively blank, and is ignored.  If you want a
-     literal '#', escape it with a backslash (e.g., '\#').  Comments may
-     appear on any line in the makefile, although they are treated
-     specially in certain situations.
-
-     You cannot use comments within variable references or function
-     calls: any instance of '#' will be treated literally (rather than
-     as the start of a comment) inside a variable reference or function
-     call.
-
-     Comments within a recipe are passed to the shell, just as with any
-     other recipe text.  The shell decides how to interpret it: whether
-     or not this is a comment is up to the shell.
-
-     Within a 'define' directive, comments are not ignored during the
-     definition of the variable, but rather kept intact in the value of
-     the variable.  When the variable is expanded they will either be
-     treated as 'make' comments or as recipe text, depending on the
-     context in which the variable is evaluated.

-* Splitting Lines::             Splitting long lines in makefiles
-
-
-File: make.info,  Node: Splitting Lines,  Prev: Makefile Contents,  Up: Makefile Contents
-
-3.1.1 Splitting Long Lines
---------------------------
-
-Makefiles use a "line-based" syntax in which the newline character is
-special and marks the end of a statement.  GNU 'make' has no limit on
-the length of a statement line, up to the amount of memory in your
-computer.
-
-   However, it is difficult to read lines which are too long to display
-without wrapping or scrolling.  So, you can format your makefiles for
-readability by adding newlines into the middle of a statement: you do
-this by escaping the internal newlines with a backslash ('\') character.
-Where we need to make a distinction we will refer to "physical lines" as
-a single line ending with a newline (regardless of whether it is
-escaped) and a "logical line" being a complete statement including all
-escaped newlines up to the first non-escaped newline.
-
-   The way in which backslash/newline combinations are handled depends
-on whether the statement is a recipe line or a non-recipe line.
-Handling of backslash/newline in a recipe line is discussed later (*note
-Splitting Recipe Lines::).
-
-   Outside of recipe lines, backslash/newlines are converted into a
-single space character.  Once that is done, all whitespace around the
-backslash/newline is condensed into a single space: this includes all
-whitespace preceding the backslash, all whitespace at the beginning of
-the line after the backslash/newline, and any consecutive
-backslash/newline combinations.
-
-   If the '.POSIX' special target is defined then backslash/newline
-handling is modified slightly to conform to POSIX.2: first, whitespace
-preceding a backslash is not removed and second, consecutive
-backslash/newlines are not condensed.
-
-Splitting Without Adding Whitespace
-...................................
-
-If you need to split a line but do _not_ want any whitespace added, you
-can utilize a subtle trick: replace your backslash/newline pairs with
-the three characters dollar sign/backslash/newline:
-
-     var := one$\
-            word
-
-   After 'make' removes the backslash/newline and condenses the
-following line into a single space, this is equivalent to:
-
-     var := one$ word
-
-   Then 'make' will perform variable expansion.  The variable reference
-'$ ' refers to a variable with the one-character name " " (space) which
-does not exist, and so expands to the empty string, giving a final
-assignment which is the equivalent of:
-
-     var := oneword
-

-
-3.2 What Name to Give Your Makefile
-===================================
-
-By default, when 'make' looks for the makefile, it tries the following
-names, in order: 'GNUmakefile', 'makefile' and 'Makefile'.
-
-   Normally you should call your makefile either 'makefile' or
-'Makefile'.  (We recommend 'Makefile' because it appears prominently
-near the beginning of a directory listing, right near other important
-files such as 'README'.)  The first name checked, 'GNUmakefile', is not
-recommended for most makefiles.  You should use this name if you have a
-makefile that is specific to GNU 'make', and will not be understood by
-other versions of 'make'.  Other 'make' programs look for 'makefile' and
-'Makefile', but not 'GNUmakefile'.
-
-   If 'make' finds none of these names, it does not use any makefile.
-Then you must specify a goal with a command argument, and 'make' will
-attempt to figure out how to remake it using only its built-in implicit
-rules.  *Note Using Implicit Rules: Implicit Rules.
-
-   If you want to use a nonstandard name for your makefile, you can
-specify the makefile name with the '-f' or '--file' option.  The
-arguments '-f NAME' or '--file=NAME' tell 'make' to read the file NAME
-as the makefile.  If you use more than one '-f' or '--file' option, you
-can specify several makefiles.  All the makefiles are effectively
-concatenated in the order specified.  The default makefile names
-'GNUmakefile', 'makefile' and 'Makefile' are not checked automatically
-if you specify '-f' or '--file'.
-
-
-File: make.info,  Node: Include,  Next: MAKEFILES Variable,  Prev: Makefile Names,  Up: Makefiles
-
-3.3 Including Other Makefiles
-=============================
-
-The 'include' directive tells 'make' to suspend reading the current
-makefile and read one or more other makefiles before continuing.  The
-directive is a line in the makefile that looks like this:
-
-     include FILENAMES...
-
-FILENAMES can contain shell file name patterns.  If FILENAMES is empty,
-nothing is included and no error is printed.
-
-   Extra spaces are allowed and ignored at the beginning of the line,
-but the first character must not be a tab (or the value of
-'.RECIPEPREFIX')--if the line begins with a tab, it will be considered a
-recipe line.  Whitespace is required between 'include' and the file
-names, and between file names; extra whitespace is ignored there and at
-the end of the directive.  A comment starting with '#' is allowed at the
-end of the line.  If the file names contain any variable or function
-references, they are expanded.  *Note How to Use Variables: Using
-Variables.
-
-   For example, if you have three '.mk' files, 'a.mk', 'b.mk', and
-'c.mk', and '$(bar)' expands to 'bish bash', then the following
-expression
-
-     include foo *.mk $(bar)
-
-   is equivalent to
-
-     include foo a.mk b.mk c.mk bish bash
-
-   When 'make' processes an 'include' directive, it suspends reading of
-the containing makefile and reads from each listed file in turn.  When
-that is finished, 'make' resumes reading the makefile in which the
-directive appears.
-
-   One occasion for using 'include' directives is when several programs,
-handled by individual makefiles in various directories, need to use a
-common set of variable definitions (*note Setting Variables: Setting.)
-or pattern rules (*note Defining and Redefining Pattern Rules: Pattern
-Rules.).
-
-   Another such occasion is when you want to generate prerequisites from
-source files automatically; the prerequisites can be put in a file that
-is included by the main makefile.  This practice is generally cleaner
-than that of somehow appending the prerequisites to the end of the main
-makefile as has been traditionally done with other versions of 'make'.
-*Note Automatic Prerequisites::.
-
-   If the specified name does not start with a slash, and the file is
-not found in the current directory, several other directories are
-searched.  First, any directories you have specified with the '-I' or
-'--include-dir' option are searched (*note Summary of Options: Options
-Summary.).  Then the following directories (if they exist) are searched,
-in this order: 'PREFIX/include' (normally '/usr/local/include' (1))
-'/usr/gnu/include', '/usr/local/include', '/usr/include'.
-
-   If an included makefile cannot be found in any of these directories,
-a warning message is generated, but it is not an immediately fatal
-error; processing of the makefile containing the 'include' continues.
-Once it has finished reading makefiles, 'make' will try to remake any
-that are out of date or don't exist.  *Note How Makefiles Are Remade:
-Remaking Makefiles.  Only after it has tried to find a way to remake a
-makefile and failed, will 'make' diagnose the missing makefile as a
-fatal error.
-
-   If you want 'make' to simply ignore a makefile which does not exist
-or cannot be remade, with no error message, use the '-include' directive
-instead of 'include', like this:
-
-     -include FILENAMES...
-
-   This acts like 'include' in every way except that there is no error
-(not even a warning) if any of the FILENAMES (or any prerequisites of
-any of the FILENAMES) do not exist or cannot be remade.
-
-   For compatibility with some other 'make' implementations, 'sinclude'
-is another name for '-include'.

-has been defined to be the root of the DJGPP tree hierarchy.

-
-3.4 The Variable 'MAKEFILES'
-============================
-
-If the environment variable 'MAKEFILES' is defined, 'make' considers its
-value as a list of names (separated by whitespace) of additional
-makefiles to be read before the others.  This works much like the
-'include' directive: various directories are searched for those files
-(*note Including Other Makefiles: Include.).  In addition, the default
-goal is never taken from one of these makefiles (or any makefile
-included by them) and it is not an error if the files listed in
-'MAKEFILES' are not found.
-
-   The main use of 'MAKEFILES' is in communication between recursive
-invocations of 'make' (*note Recursive Use of 'make': Recursion.).  It
-usually is not desirable to set the environment variable before a
-top-level invocation of 'make', because it is usually better not to mess
-with a makefile from outside.  However, if you are running 'make'
-without a specific makefile, a makefile in 'MAKEFILES' can do useful
-things to help the built-in implicit rules work better, such as defining
-search paths (*note Directory Search::).
-
-   Some users are tempted to set 'MAKEFILES' in the environment
-automatically on login, and program makefiles to expect this to be done.
-This is a very bad idea, because such makefiles will fail to work if run
-by anyone else.  It is much better to write explicit 'include'
-directives in the makefiles.  *Note Including Other Makefiles: Include.
-
-
-File: make.info,  Node: Remaking Makefiles,  Next: Overriding Makefiles,  Prev: MAKEFILES Variable,  Up: Makefiles
-
-3.5 How Makefiles Are Remade
-============================
-
-Sometimes makefiles can be remade from other files, such as RCS or SCCS
-files.  If a makefile can be remade from other files, you probably want
-'make' to get an up-to-date version of the makefile to read in.
-
-   To this end, after reading in all makefiles 'make' will consider each
-as a goal target and attempt to update it.  If a makefile has a rule
-which says how to update it (found either in that very makefile or in
-another one) or if an implicit rule applies to it (*note Using Implicit
-Rules: Implicit Rules.), it will be updated if necessary.  After all
-makefiles have been checked, if any have actually been changed, 'make'
-starts with a clean slate and reads all the makefiles over again.  (It
-will also attempt to update each of them over again, but normally this
-will not change them again, since they are already up to date.)  Each
-restart will cause the special variable 'MAKE_RESTARTS' to be updated
-(*note Special Variables::).
-
-   If you know that one or more of your makefiles cannot be remade and
-you want to keep 'make' from performing an implicit rule search on them,
-perhaps for efficiency reasons, you can use any normal method of
-preventing implicit rule look-up to do so.  For example, you can write
-an explicit rule with the makefile as the target, and an empty recipe
-(*note Using Empty Recipes: Empty Recipes.).
-
-   If the makefiles specify a double-colon rule to remake a file with a
-recipe but no prerequisites, that file will always be remade (*note
-Double-Colon::).  In the case of makefiles, a makefile that has a
-double-colon rule with a recipe but no prerequisites will be remade
-every time 'make' is run, and then again after 'make' starts over and
-reads the makefiles in again.  This would cause an infinite loop: 'make'
-would constantly remake the makefile, and never do anything else.  So,
-to avoid this, 'make' will *not* attempt to remake makefiles which are
-specified as targets of a double-colon rule with a recipe but no
-prerequisites.
-
-   If you do not specify any makefiles to be read with '-f' or '--file'
-options, 'make' will try the default makefile names; *note What Name to
-Give Your Makefile: Makefile Names.  Unlike makefiles explicitly
-requested with '-f' or '--file' options, 'make' is not certain that
-these makefiles should exist.  However, if a default makefile does not
-exist but can be created by running 'make' rules, you probably want the
-rules to be run so that the makefile can be used.
-
-   Therefore, if none of the default makefiles exists, 'make' will try
-to make each of them in the same order in which they are searched for
-(*note What Name to Give Your Makefile: Makefile Names.) until it
-succeeds in making one, or it runs out of names to try.  Note that it is
-not an error if 'make' cannot find or make any makefile; a makefile is
-not always necessary.
-
-   When you use the '-t' or '--touch' option (*note Instead of Executing
-Recipes: Instead of Execution.), you would not want to use an
-out-of-date makefile to decide which targets to touch.  So the '-t'
-option has no effect on updating makefiles; they are really updated even
-if '-t' is specified.  Likewise, '-q' (or '--question') and '-n' (or
-'--just-print') do not prevent updating of makefiles, because an
-out-of-date makefile would result in the wrong output for other targets.
-Thus, 'make -f mfile -n foo' will update 'mfile', read it in, and then
-print the recipe to update 'foo' and its prerequisites without running
-it.  The recipe printed for 'foo' will be the one specified in the
-updated contents of 'mfile'.
-
-   However, on occasion you might actually wish to prevent updating of
-even the makefiles.  You can do this by specifying the makefiles as
-goals in the command line as well as specifying them as makefiles.  When
-the makefile name is specified explicitly as a goal, the options '-t'
-and so on do apply to them.
-
-   Thus, 'make -f mfile -n mfile foo' would read the makefile 'mfile',
-print the recipe needed to update it without actually running it, and
-then print the recipe needed to update 'foo' without running that.  The
-recipe for 'foo' will be the one specified by the existing contents of
-'mfile'.
-

-
-3.6 Overriding Part of Another Makefile
-=======================================
-
-Sometimes it is useful to have a makefile that is mostly just like
-another makefile.  You can often use the 'include' directive to include
-one in the other, and add more targets or variable definitions.
-However, it is invalid for two makefiles to give different recipes for
-the same target.  But there is another way.
-
-   In the containing makefile (the one that wants to include the other),
-you can use a match-anything pattern rule to say that to remake any
-target that cannot be made from the information in the containing
-makefile, 'make' should look in another makefile.  *Note Pattern
-Rules::, for more information on pattern rules.
-
-   For example, if you have a makefile called 'Makefile' that says how
-to make the target 'foo' (and other targets), you can write a makefile
-called 'GNUmakefile' that contains:
-
-     foo:
-             frobnicate > foo
-
-     %: force
-             @$(MAKE) -f Makefile $@
-     force: ;
-
-   If you say 'make foo', 'make' will find 'GNUmakefile', read it, and
-see that to make 'foo', it needs to run the recipe 'frobnicate > foo'.
-If you say 'make bar', 'make' will find no way to make 'bar' in
-'GNUmakefile', so it will use the recipe from the pattern rule: 'make -f
-Makefile bar'.  If 'Makefile' provides a rule for updating 'bar', 'make'
-will apply the rule.  And likewise for any other target that
-'GNUmakefile' does not say how to make.
-
-   The way this works is that the pattern rule has a pattern of just
-'%', so it matches any target whatever.  The rule specifies a
-prerequisite 'force', to guarantee that the recipe will be run even if
-the target file already exists.  We give the 'force' target an empty
-recipe to prevent 'make' from searching for an implicit rule to build
-it--otherwise it would apply the same match-anything rule to 'force'
-itself and create a prerequisite loop!

-
-3.7 How 'make' Reads a Makefile
-===============================
-
-GNU 'make' does its work in two distinct phases.  During the first phase
-it reads all the makefiles, included makefiles, etc.  and internalizes
-all the variables and their values and implicit and explicit rules, and
-builds a dependency graph of all the targets and their prerequisites.
-During the second phase, 'make' uses this internalized data to determine
-which targets need to be updated and run the recipes necessary to update
-them.
-
-   It's important to understand this two-phase approach because it has a
-direct impact on how variable and function expansion happens; this is
-often a source of some confusion when writing makefiles.  Below is a
-summary of the different constructs that can be found in a makefile, and
-the phase in which expansion happens for each part of the construct.
-
-   We say that expansion is "immediate" if it happens during the first
-phase: 'make' will expand that part of the construct as the makefile is
-parsed.  We say that expansion is "deferred" if it is not immediate.
-Expansion of a deferred construct part is delayed until the expansion is
-used: either when it is referenced in an immediate context, or when it
-is needed during the second phase.
-
-   You may not be familiar with some of these constructs yet.  You can
-reference this section as you become familiar with them, in later
-chapters.
-
-Variable Assignment
--------------------
-
-Variable definitions are parsed as follows:
-
-     IMMEDIATE = DEFERRED
-     IMMEDIATE ?= DEFERRED
-     IMMEDIATE := IMMEDIATE
-     IMMEDIATE ::= IMMEDIATE
-     IMMEDIATE += DEFERRED or IMMEDIATE
-     IMMEDIATE != IMMEDIATE
-
-     define IMMEDIATE
-       DEFERRED
-     endef
-
-     define IMMEDIATE =
-       DEFERRED
-     endef
-
-     define IMMEDIATE ?=
-       DEFERRED

-     define IMMEDIATE +=
-       DEFERRED or IMMEDIATE
-     endef
-
-     define IMMEDIATE !=
-       IMMEDIATE
-     endef
-
-   For the append operator '+=', the right-hand side is considered
-immediate if the variable was previously set as a simple variable (':='
-or '::='), and deferred otherwise.
-
-   For the shell assignment operator '!=', the right-hand side is
-evaluated immediately and handed to the shell.  The result is stored in
-the variable named on the left, and that variable becomes a simple
-variable (and will thus be re-evaluated on each reference).
-
-Conditional Directives
-----------------------
-
-Conditional directives are parsed immediately.  This means, for example,
-that automatic variables cannot be used in conditional directives, as
-automatic variables are not set until the recipe for that rule is
-invoked.  If you need to use automatic variables in a conditional
-directive you _must_ move the condition into the recipe and use shell
-conditional syntax instead.
-
-Rule Definition
----------------
-
-A rule is always expanded the same way, regardless of the form:
-
-     IMMEDIATE : IMMEDIATE ; DEFERRED
-             DEFERRED
-
-   That is, the target and prerequisite sections are expanded
-immediately, and the recipe used to build the target is always deferred.
-This is true for explicit rules, pattern rules, suffix rules, static
-pattern rules, and simple prerequisite definitions.

-3.8 How Makefiles Are Parsed
-============================
-
-GNU 'make' parses makefiles line-by-line.  Parsing proceeds using the
-following steps:
-
-  1. Read in a full logical line, including backslash-escaped lines
-     (*note Splitting Long Lines: Splitting Lines.).
-
-  2. Remove comments (*note What Makefiles Contain: Makefile Contents.).
-
-  3. If the line begins with the recipe prefix character and we are in a
-     rule context, add the line to the current recipe and read the next
-     line (*note Recipe Syntax::).
-
-  4. Expand elements of the line which appear in an _immediate_
-     expansion context (*note How 'make' Reads a Makefile: Reading
-     Makefiles.).
-
-  5. Scan the line for a separator character, such as ':' or '=', to
-     determine whether the line is a macro assignment or a rule (*note
-     Recipe Syntax::).
-
-  6. Internalize the resulting operation and read the next line.
-
-   An important consequence of this is that a macro can expand to an
-entire rule, _if it is one line long_.  This will work:
-
-     myrule = target : ; echo built
-
-     $(myrule)
-
-   However, this will not work because 'make' does not re-split lines
-after it has expanded them:
-
-     define myrule
-     target:
-             echo built
-     endef
-
-     $(myrule)
-
-   The above makefile results in the definition of a target 'target'
-with prerequisites 'echo' and 'built', as if the makefile contained
-'target: echo built', rather than a rule with a recipe.  Newlines still
-present in a line after expansion is complete are ignored as normal
-whitespace.
-
-   In order to properly expand a multi-line macro you must use the
-'eval' function: this causes the 'make' parser to be run on the results
-of the expanded macro (*note Eval Function::).

-
-3.9 Secondary Expansion
-=======================
-
-Previously we learned that GNU 'make' works in two distinct phases: a
-read-in phase and a target-update phase (*note How 'make' Reads a
-Makefile: Reading Makefiles.).  GNU make also has the ability to enable
-a _second expansion_ of the prerequisites (only) for some or all targets
-defined in the makefile.  In order for this second expansion to occur,
-the special target '.SECONDEXPANSION' must be defined before the first
-prerequisite list that makes use of this feature.
-
-   If that special target is defined then in between the two phases
-mentioned above, right at the end of the read-in phase, all the
-prerequisites of the targets defined after the special target are
-expanded a _second time_.  In most circumstances this secondary
-expansion will have no effect, since all variable and function
-references will have been expanded during the initial parsing of the
-makefiles.  In order to take advantage of the secondary expansion phase
-of the parser, then, it's necessary to _escape_ the variable or function
-reference in the makefile.  In this case the first expansion merely
-un-escapes the reference but doesn't expand it, and expansion is left to
-the secondary expansion phase.  For example, consider this makefile:
-
-     .SECONDEXPANSION:
-     ONEVAR = onefile
-     TWOVAR = twofile
-     myfile: $(ONEVAR) $$(TWOVAR)
-
-   After the first expansion phase the prerequisites list of the
-'myfile' target will be 'onefile' and '$(TWOVAR)'; the first (unescaped)
-variable reference to ONEVAR is expanded, while the second (escaped)
-variable reference is simply unescaped, without being recognized as a
-variable reference.  Now during the secondary expansion the first word
-is expanded again but since it contains no variable or function
-references it remains the value 'onefile', while the second word is now
-a normal reference to the variable TWOVAR, which is expanded to the
-value 'twofile'.  The final result is that there are two prerequisites,
-'onefile' and 'twofile'.
-
-   Obviously, this is not a very interesting case since the same result
-could more easily have been achieved simply by having both variables
-appear, unescaped, in the prerequisites list.  One difference becomes
-apparent if the variables are reset; consider this example:
-
-     .SECONDEXPANSION:
-     AVAR = top
-     onefile: $(AVAR)
-     twofile: $$(AVAR)
-     AVAR = bottom
-
-   Here the prerequisite of 'onefile' will be expanded immediately, and
-resolve to the value 'top', while the prerequisite of 'twofile' will not
-be full expanded until the secondary expansion and yield a value of
-'bottom'.
-
-   This is marginally more exciting, but the true power of this feature
-only becomes apparent when you discover that secondary expansions always
-take place within the scope of the automatic variables for that target.
-This means that you can use variables such as '$@', '$*', etc.  during
-the second expansion and they will have their expected values, just as
-in the recipe.  All you have to do is defer the expansion by escaping
-the '$'.  Also, secondary expansion occurs for both explicit and
-implicit (pattern) rules.  Knowing this, the possible uses for this
-feature increase dramatically.  For example:
-
-     .SECONDEXPANSION:
-     main_OBJS := main.o try.o test.o
-     lib_OBJS := lib.o api.o
-
-     main lib: $$($$@_OBJS)
-
-   Here, after the initial expansion the prerequisites of both the
-'main' and 'lib' targets will be '$($@_OBJS)'.  During the secondary
-expansion, the '$@' variable is set to the name of the target and so the
-expansion for the 'main' target will yield '$(main_OBJS)', or 'main.o
-try.o test.o', while the secondary expansion for the 'lib' target will
-yield '$(lib_OBJS)', or 'lib.o api.o'.
-
-   You can also mix in functions here, as long as they are properly
-escaped:
-
-     main_SRCS := main.c try.c test.c
-     lib_SRCS := lib.c api.c
-
-     .SECONDEXPANSION:
-     main lib: $$(patsubst %.c,%.o,$$($$@_SRCS))
-
-   This version allows users to specify source files rather than object
-files, but gives the same resulting prerequisites list as the previous
-example.
-
-   Evaluation of automatic variables during the secondary expansion
-phase, especially of the target name variable '$$@', behaves similarly
-to evaluation within recipes.  However, there are some subtle
-differences and "corner cases" which come into play for the different
-types of rule definitions that 'make' understands.  The subtleties of
-using the different automatic variables are described below.
-
-Secondary Expansion of Explicit Rules
--------------------------------------
-
-During the secondary expansion of explicit rules, '$$@' and '$$%'
-evaluate, respectively, to the file name of the target and, when the
-target is an archive member, the target member name.  The '$$<' variable
-evaluates to the first prerequisite in the first rule for this target.
-'$$^' and '$$+' evaluate to the list of all prerequisites of rules _that
-have already appeared_ for the same target ('$$+' with repetitions and
-'$$^' without).  The following example will help illustrate these
-behaviors:
-
-     .SECONDEXPANSION:
-
-     foo: foo.1 bar.1 $$< $$^ $$+    # line #1
-
-     foo: foo.2 bar.2 $$< $$^ $$+    # line #2
-
-     foo: foo.3 bar.3 $$< $$^ $$+    # line #3
-
-   In the first prerequisite list, all three variables ('$$<', '$$^',
-and '$$+') expand to the empty string.  In the second, they will have
-values 'foo.1', 'foo.1 bar.1', and 'foo.1 bar.1' respectively.  In the
-third they will have values 'foo.1', 'foo.1 bar.1 foo.2 bar.2', and
-'foo.1 bar.1 foo.2 bar.2 foo.1 foo.1 bar.1 foo.1 bar.1' respectively.
-
-   Rules undergo secondary expansion in makefile order, except that the
-rule with the recipe is always evaluated last.
-
-   The variables '$$?' and '$$*' are not available and expand to the
-empty string.
-
-Secondary Expansion of Static Pattern Rules
--------------------------------------------
-
-Rules for secondary expansion of static pattern rules are identical to
-those for explicit rules, above, with one exception: for static pattern
-rules the '$$*' variable is set to the pattern stem.  As with explicit
-rules, '$$?' is not available and expands to the empty string.
-
-Secondary Expansion of Implicit Rules
--------------------------------------
-
-As 'make' searches for an implicit rule, it substitutes the stem and
-then performs secondary expansion for every rule with a matching target
-pattern.  The value of the automatic variables is derived in the same
-fashion as for static pattern rules.  As an example:
-
-     .SECONDEXPANSION:
-
-     foo: bar
-
-     foo foz: fo%: bo%
-
-     %oo: $$< $$^ $$+ $$*
-
-   When the implicit rule is tried for target 'foo', '$$<' expands to
-'bar', '$$^' expands to 'bar boo', '$$+' also expands to 'bar boo', and
-'$$*' expands to 'f'.
-
-   Note that the directory prefix (D), as described in *note Implicit
-Rule Search Algorithm: Implicit Rule Search, is appended (after
-expansion) to all the patterns in the prerequisites list.  As an
-example:
-
-     .SECONDEXPANSION:
-
-     /tmp/foo.o:
-
-     %.o: $$(addsuffix /%.c,foo bar) foo.h
-             @echo $^
-
-   The prerequisite list printed, after the secondary expansion and
-directory prefix reconstruction, will be '/tmp/foo/foo.c /tmp/bar/foo.c
-foo.h'.  If you are not interested in this reconstruction, you can use
-'$$*' instead of '%' in the prerequisites list.

-4 Writing Rules
-***************
-
-A "rule" appears in the makefile and says when and how to remake certain
-files, called the rule's "targets" (most often only one per rule).  It
-lists the other files that are the "prerequisites" of the target, and
-the "recipe" to use to create or update the target.
-
-   The order of rules is not significant, except for determining the
-"default goal": the target for 'make' to consider, if you do not
-otherwise specify one.  The default goal is the target of the first rule
-in the first makefile.  If the first rule has multiple targets, only the
-first target is taken as the default.  There are two exceptions: a
-target starting with a period is not a default unless it contains one or
-more slashes, '/', as well; and, a target that defines a pattern rule
-has no effect on the default goal.  (*Note Defining and Redefining
-Pattern Rules: Pattern Rules.)
-
-   Therefore, we usually write the makefile so that the first rule is
-the one for compiling the entire program or all the programs described
-by the makefile (often with a target called 'all').  *Note Arguments to
-Specify the Goals: Goals.

-4.1 Rule Example
-================
-
-Here is an example of a rule:
-
-     foo.o : foo.c defs.h       # module for twiddling the frobs
-             cc -c -g foo.c
-
-   Its target is 'foo.o' and its prerequisites are 'foo.c' and 'defs.h'.
-It has one command in the recipe: 'cc -c -g foo.c'.  The recipe starts
-with a tab to identify it as a recipe.
-
-   This rule says two things:
-
-   * How to decide whether 'foo.o' is out of date: it is out of date if
-     it does not exist, or if either 'foo.c' or 'defs.h' is more recent
-     than it.
-
-   * How to update the file 'foo.o': by running 'cc' as stated.  The
-     recipe does not explicitly mention 'defs.h', but we presume that
-     'foo.c' includes it, and that is why 'defs.h' was added to the
-     prerequisites.
-
-

-
-4.2 Rule Syntax
-===============
-
-In general, a rule looks like this:
-
-     TARGETS : PREREQUISITES
-             RECIPE
-             ...
-
-or like this:
-
-     TARGETS : PREREQUISITES ; RECIPE
-             RECIPE
-             ...
-
-   The TARGETS are file names, separated by spaces.  Wildcard characters
-may be used (*note Using Wildcard Characters in File Names: Wildcards.)
-and a name of the form 'A(M)' represents member M in archive file A
-(*note Archive Members as Targets: Archive Members.).  Usually there is
-only one target per rule, but occasionally there is a reason to have
-more (*note Multiple Targets in a Rule: Multiple Targets.).
-
-   The RECIPE lines start with a tab character (or the first character
-in the value of the '.RECIPEPREFIX' variable; *note Special
-Variables::).  The first recipe line may appear on the line after the
-prerequisites, with a tab character, or may appear on the same line,
-with a semicolon.  Either way, the effect is the same.  There are other
-differences in the syntax of recipes.  *Note Writing Recipes in Rules:
-Recipes.
-
-   Because dollar signs are used to start 'make' variable references, if
-you really want a dollar sign in a target or prerequisite you must write
-two of them, '$$' (*note How to Use Variables: Using Variables.).  If
-you have enabled secondary expansion (*note Secondary Expansion::) and
-you want a literal dollar sign in the prerequisites list, you must
-actually write _four_ dollar signs ('$$$$').
-
-   You may split a long line by inserting a backslash followed by a
-newline, but this is not required, as 'make' places no limit on the
-length of a line in a makefile.
-
-   A rule tells 'make' two things: when the targets are out of date, and
-how to update them when necessary.
-
-   The criterion for being out of date is specified in terms of the
-PREREQUISITES, which consist of file names separated by spaces.
-(Wildcards and archive members (*note Archives::) are allowed here too.)
-A target is out of date if it does not exist or if it is older than any
-of the prerequisites (by comparison of last-modification times).  The
-idea is that the contents of the target file are computed based on
-information in the prerequisites, so if any of the prerequisites
-changes, the contents of the existing target file are no longer
-necessarily valid.
-
-   How to update is specified by a RECIPE.  This is one or more lines to
-be executed by the shell (normally 'sh'), but with some extra features
-(*note Writing Recipes in Rules: Recipes.).
-
-
-File: make.info,  Node: Prerequisite Types,  Next: Wildcards,  Prev: Rule Syntax,  Up: Rules
-
-4.3 Types of Prerequisites
-==========================
-
-There are actually two different types of prerequisites understood by
-GNU 'make': normal prerequisites such as described in the previous
-section, and "order-only" prerequisites.  A normal prerequisite makes
-two statements: first, it imposes an order in which recipes will be
-invoked: the recipes for all prerequisites of a target will be completed
-before the recipe for the target is run.  Second, it imposes a
-dependency relationship: if any prerequisite is newer than the target,
-then the target is considered out-of-date and must be rebuilt.
-
-   Normally, this is exactly what you want: if a target's prerequisite
-is updated, then the target should also be updated.
-
-   Occasionally, however, you have a situation where you want to impose
-a specific ordering on the rules to be invoked _without_ forcing the
-target to be updated if one of those rules is executed.  In that case,
-you want to define "order-only" prerequisites.  Order-only prerequisites
-can be specified by placing a pipe symbol ('|') in the prerequisites
-list: any prerequisites to the left of the pipe symbol are normal; any
-prerequisites to the right are order-only:
-
-     TARGETS : NORMAL-PREREQUISITES | ORDER-ONLY-PREREQUISITES
-
-   The normal prerequisites section may of course be empty.  Also, you
-may still declare multiple lines of prerequisites for the same target:
-they are appended appropriately (normal prerequisites are appended to
-the list of normal prerequisites; order-only prerequisites are appended
-to the list of order-only prerequisites).  Note that if you declare the
-same file to be both a normal and an order-only prerequisite, the normal
-prerequisite takes precedence (since they have a strict superset of the
-behavior of an order-only prerequisite).
-
-   Consider an example where your targets are to be placed in a separate
-directory, and that directory might not exist before 'make' is run.  In
-this situation, you want the directory to be created before any targets
-are placed into it but, because the timestamps on directories change
-whenever a file is added, removed, or renamed, we certainly don't want
-to rebuild all the targets whenever the directory's timestamp changes.
-One way to manage this is with order-only prerequisites: make the
-directory an order-only prerequisite on all the targets:
-
-     OBJDIR := objdir
-     OBJS := $(addprefix $(OBJDIR)/,foo.o bar.o baz.o)
-
-     $(OBJDIR)/%.o : %.c
-             $(COMPILE.c) $(OUTPUT_OPTION) $<
-
-     all: $(OBJS)
-
-     $(OBJS): | $(OBJDIR)
-
-     $(OBJDIR):
-             mkdir $(OBJDIR)
-
-   Now the rule to create the 'objdir' directory will be run, if needed,
-before any '.o' is built, but no '.o' will be built because the 'objdir'
-directory timestamp changed.

-
-4.4 Using Wildcard Characters in File Names
-===========================================
-
-A single file name can specify many files using "wildcard characters".
-The wildcard characters in 'make' are '*', '?' and '[...]', the same as
-in the Bourne shell.  For example, '*.c' specifies a list of all the
-files (in the working directory) whose names end in '.c'.
-
-   The character '~' at the beginning of a file name also has special
-significance.  If alone, or followed by a slash, it represents your home
-directory.  For example '~/bin' expands to '/home/you/bin'.  If the '~'
-is followed by a word, the string represents the home directory of the
-user named by that word.  For example '~john/bin' expands to
-'/home/john/bin'.  On systems which don't have a home directory for each
-user (such as MS-DOS or MS-Windows), this functionality can be simulated
-by setting the environment variable HOME.
-
-   Wildcard expansion is performed by 'make' automatically in targets
-and in prerequisites.  In recipes, the shell is responsible for wildcard
-expansion.  In other contexts, wildcard expansion happens only if you
-request it explicitly with the 'wildcard' function.
-
-   The special significance of a wildcard character can be turned off by
-preceding it with a backslash.  Thus, 'foo\*bar' would refer to a
-specific file whose name consists of 'foo', an asterisk, and 'bar'.

-
-4.4.1 Wildcard Examples
------------------------
-
-Wildcards can be used in the recipe of a rule, where they are expanded
-by the shell.  For example, here is a rule to delete all the object
-files:
-
-     clean:
-             rm -f *.o
-
-   Wildcards are also useful in the prerequisites of a rule.  With the
-following rule in the makefile, 'make print' will print all the '.c'
-files that have changed since the last time you printed them:
-
-     print: *.c
-             lpr -p $?
-             touch print
-
-This rule uses 'print' as an empty target file; see *note Empty Target
-Files to Record Events: Empty Targets.  (The automatic variable '$?' is
-used to print only those files that have changed; see *note Automatic
-Variables::.)
-
-   Wildcard expansion does not happen when you define a variable.  Thus,
-if you write this:
-
-     objects = *.o
-
-then the value of the variable 'objects' is the actual string '*.o'.
-However, if you use the value of 'objects' in a target or prerequisite,
-wildcard expansion will take place there.  If you use the value of
-'objects' in a recipe, the shell may perform wildcard expansion when the
-recipe runs.  To set 'objects' to the expansion, instead use:
-
-     objects := $(wildcard *.o)
-
-*Note Wildcard Function::.

-
-4.4.2 Pitfalls of Using Wildcards
----------------------------------
-
-Now here is an example of a naive way of using wildcard expansion, that
-does not do what you would intend.  Suppose you would like to say that
-the executable file 'foo' is made from all the object files in the
-directory, and you write this:
-
-     objects = *.o
-
-     foo : $(objects)
-             cc -o foo $(CFLAGS) $(objects)
-
-The value of 'objects' is the actual string '*.o'.  Wildcard expansion
-happens in the rule for 'foo', so that each _existing_ '.o' file becomes
-a prerequisite of 'foo' and will be recompiled if necessary.
-
-   But what if you delete all the '.o' files?  When a wildcard matches
-no files, it is left as it is, so then 'foo' will depend on the
-oddly-named file '*.o'.  Since no such file is likely to exist, 'make'
-will give you an error saying it cannot figure out how to make '*.o'.
-This is not what you want!
-
-   Actually it is possible to obtain the desired result with wildcard
-expansion, but you need more sophisticated techniques, including the
-'wildcard' function and string substitution.  *Note The Function
-'wildcard': Wildcard Function.
-
-   Microsoft operating systems (MS-DOS and MS-Windows) use backslashes
-to separate directories in pathnames, like so:
-
-       c:\foo\bar\baz.c
-
-   This is equivalent to the Unix-style 'c:/foo/bar/baz.c' (the 'c:'
-part is the so-called drive letter).  When 'make' runs on these systems,
-it supports backslashes as well as the Unix-style forward slashes in
-pathnames.  However, this support does _not_ include the wildcard
-expansion, where backslash is a quote character.  Therefore, you _must_
-use Unix-style slashes in these cases.

-
-4.4.3 The Function 'wildcard'
------------------------------
-
-Wildcard expansion happens automatically in rules.  But wildcard
-expansion does not normally take place when a variable is set, or inside
-the arguments of a function.  If you want to do wildcard expansion in
-such places, you need to use the 'wildcard' function, like this:
-
-     $(wildcard PATTERN...)
-
-This string, used anywhere in a makefile, is replaced by a
-space-separated list of names of existing files that match one of the
-given file name patterns.  If no existing file name matches a pattern,
-then that pattern is omitted from the output of the 'wildcard' function.
-Note that this is different from how unmatched wildcards behave in
-rules, where they are used verbatim rather than ignored (*note Wildcard
-Pitfall::).
-
-   One use of the 'wildcard' function is to get a list of all the C
-source files in a directory, like this:
-
-     $(wildcard *.c)
-
-   We can change the list of C source files into a list of object files
-by replacing the '.c' suffix with '.o' in the result, like this:
-
-     $(patsubst %.c,%.o,$(wildcard *.c))
-
-(Here we have used another function, 'patsubst'.  *Note Functions for
-String Substitution and Analysis: Text Functions.)
-
-   Thus, a makefile to compile all C source files in the directory and
-then link them together could be written as follows:
-
-     objects := $(patsubst %.c,%.o,$(wildcard *.c))
-
-     foo : $(objects)
-             cc -o foo $(objects)
-
-(This takes advantage of the implicit rule for compiling C programs, so
-there is no need to write explicit rules for compiling the files.  *Note
-The Two Flavors of Variables: Flavors, for an explanation of ':=', which
-is a variant of '='.)

-4.5 Searching Directories for Prerequisites
-===========================================
-
-For large systems, it is often desirable to put sources in a separate
-directory from the binaries.  The "directory search" features of 'make'
-facilitate this by searching several directories automatically to find a
-prerequisite.  When you redistribute the files among directories, you do
-not need to change the individual rules, just the search paths.

-4.5.1 'VPATH': Search Path for All Prerequisites
-------------------------------------------------
-
-The value of the 'make' variable 'VPATH' specifies a list of directories
-that 'make' should search.  Most often, the directories are expected to
-contain prerequisite files that are not in the current directory;
-however, 'make' uses 'VPATH' as a search list for both prerequisites and
-targets of rules.
-
-   Thus, if a file that is listed as a target or prerequisite does not
-exist in the current directory, 'make' searches the directories listed
-in 'VPATH' for a file with that name.  If a file is found in one of
-them, that file may become the prerequisite (see below).  Rules may then
-specify the names of files in the prerequisite list as if they all
-existed in the current directory.  *Note Writing Recipes with Directory
-Search: Recipes/Search.
-
-   In the 'VPATH' variable, directory names are separated by colons or
-blanks.  The order in which directories are listed is the order followed
-by 'make' in its search.  (On MS-DOS and MS-Windows, semi-colons are
-used as separators of directory names in 'VPATH', since the colon can be
-used in the pathname itself, after the drive letter.)
-
-   For example,
-
-     VPATH = src:../headers
-
-specifies a path containing two directories, 'src' and '../headers',
-which 'make' searches in that order.
-
-   With this value of 'VPATH', the following rule,
-
-     foo.o : foo.c
-
-is interpreted as if it were written like this:
-
-     foo.o : src/foo.c
-
-assuming the file 'foo.c' does not exist in the current directory but is
-found in the directory 'src'.
-
-
-File: make.info,  Node: Selective Search,  Next: Search Algorithm,  Prev: General Search,  Up: Directory Search
-
-4.5.2 The 'vpath' Directive
----------------------------
-
-Similar to the 'VPATH' variable, but more selective, is the 'vpath'
-directive (note lower case), which allows you to specify a search path
-for a particular class of file names: those that match a particular
-pattern.  Thus you can supply certain search directories for one class
-of file names and other directories (or none) for other file names.
-
-   There are three forms of the 'vpath' directive:
-
-'vpath PATTERN DIRECTORIES'
-     Specify the search path DIRECTORIES for file names that match
-     PATTERN.
-
-     The search path, DIRECTORIES, is a list of directories to be
-     searched, separated by colons (semi-colons on MS-DOS and
-     MS-Windows) or blanks, just like the search path used in the
-     'VPATH' variable.
-
-'vpath PATTERN'
-     Clear out the search path associated with PATTERN.
-
-'vpath'
-
-     Clear all search paths previously specified with 'vpath'
-     directives.
-
-   A 'vpath' pattern is a string containing a '%' character.  The string
-must match the file name of a prerequisite that is being searched for,
-the '%' character matching any sequence of zero or more characters (as
-in pattern rules; *note Defining and Redefining Pattern Rules: Pattern
-Rules.).  For example, '%.h' matches files that end in '.h'.  (If there
-is no '%', the pattern must match the prerequisite exactly, which is not
-useful very often.)
-
-   '%' characters in a 'vpath' directive's pattern can be quoted with
-preceding backslashes ('\').  Backslashes that would otherwise quote '%'
-characters can be quoted with more backslashes.  Backslashes that quote
-'%' characters or other backslashes are removed from the pattern before
-it is compared to file names.  Backslashes that are not in danger of
-quoting '%' characters go unmolested.
-
-   When a prerequisite fails to exist in the current directory, if the
-PATTERN in a 'vpath' directive matches the name of the prerequisite
-file, then the DIRECTORIES in that directive are searched just like (and
-before) the directories in the 'VPATH' variable.
-
-   For example,
-
-     vpath %.h ../headers
-
-tells 'make' to look for any prerequisite whose name ends in '.h' in the
-directory '../headers' if the file is not found in the current
-directory.
-
-   If several 'vpath' patterns match the prerequisite file's name, then
-'make' processes each matching 'vpath' directive one by one, searching
-all the directories mentioned in each directive.  'make' handles
-multiple 'vpath' directives in the order in which they appear in the
-makefile; multiple directives with the same pattern are independent of
-each other.
-
-   Thus,
-
-     vpath %.c foo
-     vpath %   blish
-     vpath %.c bar
-
-will look for a file ending in '.c' in 'foo', then 'blish', then 'bar',
-while
-
-     vpath %.c foo:bar
-     vpath %   blish
-
-will look for a file ending in '.c' in 'foo', then 'bar', then 'blish'.

-
-4.5.3 How Directory Searches are Performed
-------------------------------------------
-
-When a prerequisite is found through directory search, regardless of
-type (general or selective), the pathname located may not be the one
-that 'make' actually provides you in the prerequisite list.  Sometimes
-the path discovered through directory search is thrown away.
-
-   The algorithm 'make' uses to decide whether to keep or abandon a path
-found via directory search is as follows:
-
-  1. If a target file does not exist at the path specified in the
-     makefile, directory search is performed.
-
-  2. If the directory search is successful, that path is kept and this
-     file is tentatively stored as the target.
-
-  3. All prerequisites of this target are examined using this same
-     method.
-
-  4. After processing the prerequisites, the target may or may not need
-     to be rebuilt:
-
-       a. If the target does _not_ need to be rebuilt, the path to the
-          file found during directory search is used for any
-          prerequisite lists which contain this target.  In short, if
-          'make' doesn't need to rebuild the target then you use the
-          path found via directory search.
-
-       b. If the target _does_ need to be rebuilt (is out-of-date), the
-          pathname found during directory search is _thrown away_, and
-          the target is rebuilt using the file name specified in the
-          makefile.  In short, if 'make' must rebuild, then the target
-          is rebuilt locally, not in the directory found via directory
-          search.
-
-   This algorithm may seem complex, but in practice it is quite often
-exactly what you want.
-
-   Other versions of 'make' use a simpler algorithm: if the file does
-not exist, and it is found via directory search, then that pathname is
-always used whether or not the target needs to be built.  Thus, if the
-target is rebuilt it is created at the pathname discovered during
-directory search.
-
-   If, in fact, this is the behavior you want for some or all of your
-directories, you can use the 'GPATH' variable to indicate this to
-'make'.
-
-   'GPATH' has the same syntax and format as 'VPATH' (that is, a space-
-or colon-delimited list of pathnames).  If an out-of-date target is
-found by directory search in a directory that also appears in 'GPATH',
-then that pathname is not thrown away.  The target is rebuilt using the
-expanded path.

-
-4.5.4 Writing Recipes with Directory Search
--------------------------------------------
-
-When a prerequisite is found in another directory through directory
-search, this cannot change the recipe of the rule; they will execute as
-written.  Therefore, you must write the recipe with care so that it will
-look for the prerequisite in the directory where 'make' finds it.
-
-   This is done with the "automatic variables" such as '$^' (*note
-Automatic Variables::).  For instance, the value of '$^' is a list of
-all the prerequisites of the rule, including the names of the
-directories in which they were found, and the value of '$@' is the
-target.  Thus:
-
-     foo.o : foo.c
-             cc -c $(CFLAGS) $^ -o $@
-
-(The variable 'CFLAGS' exists so you can specify flags for C compilation
-by implicit rules; we use it here for consistency so it will affect all
-C compilations uniformly; *note Variables Used by Implicit Rules:
-Implicit Variables.)
-
-   Often the prerequisites include header files as well, which you do
-not want to mention in the recipe.  The automatic variable '$<' is just
-the first prerequisite:
-
-     VPATH = src:../headers
-     foo.o : foo.c defs.h hack.h
-             cc -c $(CFLAGS) $< -o $@
-
-
-File: make.info,  Node: Implicit/Search,  Next: Libraries/Search,  Prev: Recipes/Search,  Up: Directory Search
-
-4.5.5 Directory Search and Implicit Rules
------------------------------------------
-
-The search through the directories specified in 'VPATH' or with 'vpath'
-also happens during consideration of implicit rules (*note Using
-Implicit Rules: Implicit Rules.).
-
-   For example, when a file 'foo.o' has no explicit rule, 'make'
-considers implicit rules, such as the built-in rule to compile 'foo.c'
-if that file exists.  If such a file is lacking in the current
-directory, the appropriate directories are searched for it.  If 'foo.c'
-exists (or is mentioned in the makefile) in any of the directories, the
-implicit rule for C compilation is applied.
-
-   The recipes of implicit rules normally use automatic variables as a
-matter of necessity; consequently they will use the file names found by
-directory search with no extra effort.
-
-
-File: make.info,  Node: Libraries/Search,  Prev: Implicit/Search,  Up: Directory Search
-
-4.5.6 Directory Search for Link Libraries
------------------------------------------
-
-Directory search applies in a special way to libraries used with the
-linker.  This special feature comes into play when you write a
-prerequisite whose name is of the form '-lNAME'.  (You can tell
-something strange is going on here because the prerequisite is normally
-the name of a file, and the _file name_ of a library generally looks
-like 'libNAME.a', not like '-lNAME'.)
-
-   When a prerequisite's name has the form '-lNAME', 'make' handles it
-specially by searching for the file 'libNAME.so', and, if it is not
-found, for the file 'libNAME.a' in the current directory, in directories
-specified by matching 'vpath' search paths and the 'VPATH' search path,
-and then in the directories '/lib', '/usr/lib', and 'PREFIX/lib'
-(normally '/usr/local/lib', but MS-DOS/MS-Windows versions of 'make'
-behave as if PREFIX is defined to be the root of the DJGPP installation
-tree).
-
-   For example, if there is a '/usr/lib/libcurses.a' library on your
-system (and no '/usr/lib/libcurses.so' file), then
-
-     foo : foo.c -lcurses
-             cc $^ -o $@
-
-would cause the command 'cc foo.c /usr/lib/libcurses.a -o foo' to be
-executed when 'foo' is older than 'foo.c' or than
-'/usr/lib/libcurses.a'.
-
-   Although the default set of files to be searched for is 'libNAME.so'
-and 'libNAME.a', this is customizable via the '.LIBPATTERNS' variable.
-Each word in the value of this variable is a pattern string.  When a
-prerequisite like '-lNAME' is seen, 'make' will replace the percent in
-each pattern in the list with NAME and perform the above directory
-searches using each library file name.
-
-   The default value for '.LIBPATTERNS' is 'lib%.so lib%.a', which
-provides the default behavior described above.
-
-   You can turn off link library expansion completely by setting this
-variable to an empty value.

-
-4.6 Phony Targets
-=================
-
-A phony target is one that is not really the name of a file; rather it
-is just a name for a recipe to be executed when you make an explicit
-request.  There are two reasons to use a phony target: to avoid a
-conflict with a file of the same name, and to improve performance.
-
-   If you write a rule whose recipe will not create the target file, the
-recipe will be executed every time the target comes up for remaking.
-Here is an example:
-
-     clean:
-             rm *.o temp
-
-Because the 'rm' command does not create a file named 'clean', probably
-no such file will ever exist.  Therefore, the 'rm' command will be
-executed every time you say 'make clean'.
-
-   In this example, the 'clean' target will not work properly if a file
-named 'clean' is ever created in this directory.  Since it has no
-prerequisites, 'clean' would always be considered up to date and its
-recipe would not be executed.  To avoid this problem you can explicitly
-declare the target to be phony by making it a prerequisite of the
-special target '.PHONY' (*note Special Built-in Target Names: Special
-Targets.) as follows:
-
-     .PHONY: clean
-     clean:
-             rm *.o temp
-
-Once this is done, 'make clean' will run the recipe regardless of
-whether there is a file named 'clean'.
-
-   Phony targets are also useful in conjunction with recursive
-invocations of 'make' (*note Recursive Use of 'make': Recursion.).  In
-this situation the makefile will often contain a variable which lists a
-number of sub-directories to be built.  A simplistic way to handle this
-is to define one rule with a recipe that loops over the sub-directories,
-like this:
-
-     SUBDIRS = foo bar baz
-
-     subdirs:
-             for dir in $(SUBDIRS); do \
-               $(MAKE) -C $$dir; \
-             done
-
-   There are problems with this method, however.  First, any error
-detected in a sub-make is ignored by this rule, so it will continue to
-build the rest of the directories even when one fails.  This can be
-overcome by adding shell commands to note the error and exit, but then
-it will do so even if 'make' is invoked with the '-k' option, which is
-unfortunate.  Second, and perhaps more importantly, you cannot take
-advantage of 'make''s ability to build targets in parallel (*note
-Parallel Execution: Parallel.), since there is only one rule.
-
-   By declaring the sub-directories as '.PHONY' targets (you must do
-this as the sub-directory obviously always exists; otherwise it won't be
-built) you can remove these problems:
-
-     SUBDIRS = foo bar baz
-
-     .PHONY: subdirs $(SUBDIRS)
-
-     subdirs: $(SUBDIRS)
-
-     $(SUBDIRS):
-             $(MAKE) -C $@
-
-     foo: baz
-
-   Here we've also declared that the 'foo' sub-directory cannot be built
-until after the 'baz' sub-directory is complete; this kind of
-relationship declaration is particularly important when attempting
-parallel builds.
-
-   The implicit rule search (*note Implicit Rules::) is skipped for
-'.PHONY' targets.  This is why declaring a target as '.PHONY' is good
-for performance, even if you are not worried about the actual file
-existing.
-
-   A phony target should not be a prerequisite of a real target file; if
-it is, its recipe will be run every time 'make' goes to update that
-file.  As long as a phony target is never a prerequisite of a real
-target, the phony target recipe will be executed only when the phony
-target is a specified goal (*note Arguments to Specify the Goals:
-Goals.).
-
-   Phony targets can have prerequisites.  When one directory contains
-multiple programs, it is most convenient to describe all of the programs
-in one makefile './Makefile'.  Since the target remade by default will
-be the first one in the makefile, it is common to make this a phony
-target named 'all' and give it, as prerequisites, all the individual
-programs.  For example:
-
-     all : prog1 prog2 prog3
-     .PHONY : all
-
-     prog1 : prog1.o utils.o
-             cc -o prog1 prog1.o utils.o
-
-     prog2 : prog2.o
-             cc -o prog2 prog2.o
-
-     prog3 : prog3.o sort.o utils.o
-             cc -o prog3 prog3.o sort.o utils.o
-
-Now you can say just 'make' to remake all three programs, or specify as
-arguments the ones to remake (as in 'make prog1 prog3').  Phoniness is
-not inherited: the prerequisites of a phony target are not themselves
-phony, unless explicitly declared to be so.
-
-   When one phony target is a prerequisite of another, it serves as a
-subroutine of the other.  For example, here 'make cleanall' will delete
-the object files, the difference files, and the file 'program':
-
-     .PHONY: cleanall cleanobj cleandiff
-
-     cleanall : cleanobj cleandiff
-             rm program
-
-     cleanobj :
-             rm *.o
-
-     cleandiff :
-             rm *.diff

-
-4.7 Rules without Recipes or Prerequisites
-==========================================
-
-If a rule has no prerequisites or recipe, and the target of the rule is
-a nonexistent file, then 'make' imagines this target to have been
-updated whenever its rule is run.  This implies that all targets
-depending on this one will always have their recipe run.
-
-   An example will illustrate this:
-
-     clean: FORCE
-             rm $(objects)
-     FORCE:
-
-   Here the target 'FORCE' satisfies the special conditions, so the
-target 'clean' that depends on it is forced to run its recipe.  There is
-nothing special about the name 'FORCE', but that is one name commonly
-used this way.
-
-   As you can see, using 'FORCE' this way has the same results as using
-'.PHONY: clean'.
-
-   Using '.PHONY' is more explicit and more efficient.  However, other
-versions of 'make' do not support '.PHONY'; thus 'FORCE' appears in many
-makefiles.  *Note Phony Targets::.

-
-4.8 Empty Target Files to Record Events
-=======================================
-
-The "empty target" is a variant of the phony target; it is used to hold
-recipes for an action that you request explicitly from time to time.
-Unlike a phony target, this target file can really exist; but the file's
-contents do not matter, and usually are empty.
-
-   The purpose of the empty target file is to record, with its
-last-modification time, when the rule's recipe was last executed.  It
-does so because one of the commands in the recipe is a 'touch' command
-to update the target file.
-
-   The empty target file should have some prerequisites (otherwise it
-doesn't make sense).  When you ask to remake the empty target, the
-recipe is executed if any prerequisite is more recent than the target;
-in other words, if a prerequisite has changed since the last time you
-remade the target.  Here is an example:
-
-     print: foo.c bar.c
-             lpr -p $?
-             touch print
-
-With this rule, 'make print' will execute the 'lpr' command if either
-source file has changed since the last 'make print'.  The automatic
-variable '$?' is used to print only those files that have changed (*note
-Automatic Variables::).

-
-4.9 Special Built-in Target Names
-=================================
-
-Certain names have special meanings if they appear as targets.
-
-'.PHONY'
-
-     The prerequisites of the special target '.PHONY' are considered to
-     be phony targets.  When it is time to consider such a target,
-     'make' will run its recipe unconditionally, regardless of whether a
-     file with that name exists or what its last-modification time is.
-     *Note Phony Targets: Phony Targets.
-
-'.SUFFIXES'
-
-     The prerequisites of the special target '.SUFFIXES' are the list of
-     suffixes to be used in checking for suffix rules.  *Note
-     Old-Fashioned Suffix Rules: Suffix Rules.
-
-'.DEFAULT'
-
-     The recipe specified for '.DEFAULT' is used for any target for
-     which no rules are found (either explicit rules or implicit rules).
-     *Note Last Resort::.  If a '.DEFAULT' recipe is specified, every
-     file mentioned as a prerequisite, but not as a target in a rule,
-     will have that recipe executed on its behalf.  *Note Implicit Rule
-     Search Algorithm: Implicit Rule Search.
-
-'.PRECIOUS'
-
-     The targets which '.PRECIOUS' depends on are given the following
-     special treatment: if 'make' is killed or interrupted during the
-     execution of their recipes, the target is not deleted.  *Note
-     Interrupting or Killing 'make': Interrupts.  Also, if the target is
-     an intermediate file, it will not be deleted after it is no longer
-     needed, as is normally done.  *Note Chains of Implicit Rules:
-     Chained Rules.  In this latter respect it overlaps with the
-     '.SECONDARY' special target.
-
-     You can also list the target pattern of an implicit rule (such as
-     '%.o') as a prerequisite file of the special target '.PRECIOUS' to
-     preserve intermediate files created by rules whose target patterns
-     match that file's name.
-
-'.INTERMEDIATE'
-
-     The targets which '.INTERMEDIATE' depends on are treated as
-     intermediate files.  *Note Chains of Implicit Rules: Chained Rules.
-     '.INTERMEDIATE' with no prerequisites has no effect.
-
-'.SECONDARY'
-
-     The targets which '.SECONDARY' depends on are treated as
-     intermediate files, except that they are never automatically
-     deleted.  *Note Chains of Implicit Rules: Chained Rules.
-
-     '.SECONDARY' with no prerequisites causes all targets to be treated
-     as secondary (i.e., no target is removed because it is considered
-     intermediate).
-
-'.SECONDEXPANSION'
-
-     If '.SECONDEXPANSION' is mentioned as a target anywhere in the
-     makefile, then all prerequisite lists defined _after_ it appears
-     will be expanded a second time after all makefiles have been read
-     in.  *Note Secondary Expansion: Secondary Expansion.
-
-'.DELETE_ON_ERROR'
-
-     If '.DELETE_ON_ERROR' is mentioned as a target anywhere in the
-     makefile, then 'make' will delete the target of a rule if it has
-     changed and its recipe exits with a nonzero exit status, just as it
-     does when it receives a signal.  *Note Errors in Recipes: Errors.
-
-'.IGNORE'
-
-     If you specify prerequisites for '.IGNORE', then 'make' will ignore
-     errors in execution of the recipe for those particular files.  The
-     recipe for '.IGNORE' (if any) is ignored.
-
-     If mentioned as a target with no prerequisites, '.IGNORE' says to
-     ignore errors in execution of recipes for all files.  This usage of
-     '.IGNORE' is supported only for historical compatibility.  Since
-     this affects every recipe in the makefile, it is not very useful;
-     we recommend you use the more selective ways to ignore errors in
-     specific recipes.  *Note Errors in Recipes: Errors.
-
-'.LOW_RESOLUTION_TIME'
-
-     If you specify prerequisites for '.LOW_RESOLUTION_TIME', 'make'
-     assumes that these files are created by commands that generate low
-     resolution time stamps.  The recipe for the '.LOW_RESOLUTION_TIME'
-     target are ignored.
-
-     The high resolution file time stamps of many modern file systems
-     lessen the chance of 'make' incorrectly concluding that a file is
-     up to date.  Unfortunately, some hosts do not provide a way to set
-     a high resolution file time stamp, so commands like 'cp -p' that
-     explicitly set a file's time stamp must discard its sub-second
-     part.  If a file is created by such a command, you should list it
-     as a prerequisite of '.LOW_RESOLUTION_TIME' so that 'make' does not
-     mistakenly conclude that the file is out of date.  For example:
-
-          .LOW_RESOLUTION_TIME: dst
-          dst: src
-                  cp -p src dst
-
-     Since 'cp -p' discards the sub-second part of 'src''s time stamp,
-     'dst' is typically slightly older than 'src' even when it is up to
-     date.  The '.LOW_RESOLUTION_TIME' line causes 'make' to consider
-     'dst' to be up to date if its time stamp is at the start of the
-     same second that 'src''s time stamp is in.
-
-     Due to a limitation of the archive format, archive member time
-     stamps are always low resolution.  You need not list archive
-     members as prerequisites of '.LOW_RESOLUTION_TIME', as 'make' does
-     this automatically.
-
-'.SILENT'
-
-     If you specify prerequisites for '.SILENT', then 'make' will not
-     print the recipe used to remake those particular files before
-     executing them.  The recipe for '.SILENT' is ignored.
-
-     If mentioned as a target with no prerequisites, '.SILENT' says not
-     to print any recipes before executing them.  You may also use more
-     selective ways to silence specific recipe command lines.  *Note
-     Recipe Echoing: Echoing.  If you want to silence all recipes for a
-     particular run of 'make', use the '-s' or '--silent' option (*note
-     Options Summary::).
-
-'.EXPORT_ALL_VARIABLES'
-
-     Simply by being mentioned as a target, this tells 'make' to export
-     all variables to child processes by default.  *Note Communicating
-     Variables to a Sub-'make': Variables/Recursion.
-
-'.NOTPARALLEL'
-
-     If '.NOTPARALLEL' is mentioned as a target, then this invocation of
-     'make' will be run serially, even if the '-j' option is given.  Any
-     recursively invoked 'make' command will still run recipes in
-     parallel (unless its makefile also contains this target).  Any
-     prerequisites on this target are ignored.
-
-'.ONESHELL'
-
-     If '.ONESHELL' is mentioned as a target, then when a target is
-     built all lines of the recipe will be given to a single invocation
-     of the shell rather than each line being invoked separately (*note
-     Recipe Execution: Execution.).
-
-'.POSIX'
-
-     If '.POSIX' is mentioned as a target, then the makefile will be
-     parsed and run in POSIX-conforming mode.  This does _not_ mean that
-     only POSIX-conforming makefiles will be accepted: all advanced GNU
-     'make' features are still available.  Rather, this target causes
-     'make' to behave as required by POSIX in those areas where 'make''s
-     default behavior differs.
-
-     In particular, if this target is mentioned then recipes will be
-     invoked as if the shell had been passed the '-e' flag: the first
-     failing command in a recipe will cause the recipe to fail
-     immediately.
-
-   Any defined implicit rule suffix also counts as a special target if
-it appears as a target, and so does the concatenation of two suffixes,
-such as '.c.o'.  These targets are suffix rules, an obsolete way of
-defining implicit rules (but a way still widely used).  In principle,
-any target name could be special in this way if you break it in two and
-add both pieces to the suffix list.  In practice, suffixes normally
-begin with '.', so these special target names also begin with '.'.

-4.10 Multiple Targets in a Rule
-===============================
-
-When an explicit rule has multiple targets they can be treated in one of
-two possible ways: as independent targets or as grouped targets.  The
-manner in which they are treated is determined by the separator that
-appears after the list of targets.
-
-Rules with Independent Targets
-..............................
-
-Rules that use the standard target separator, ':', define independent
-targets.  This is equivalent to writing the same rule once for each
-target, with duplicated prerequisites and recipes.  Typically, the
-recipe would use automatic variables such as '$@' to specify which
-target is being built.
-
-   Rules with independent targets are useful in two cases:
-
-   * You want just prerequisites, no recipe.  For example:
-
-          kbd.o command.o files.o: command.h
-
-     gives an additional prerequisite to each of the three object files
-     mentioned.  It is equivalent to writing:
-
-          kbd.o: command.h
-          command.o: command.h
-          files.o: command.h
-
-   * Similar recipes work for all the targets.  The automatic variable
-     '$@' can be used to substitute the particular target to be remade
-     into the commands (*note Automatic Variables::).  For example:
-
-          bigoutput littleoutput : text.g
-                  generate text.g -$(subst output,,$@) > $@
-
-     is equivalent to
-
-          bigoutput : text.g
-                  generate text.g -big > bigoutput
-          littleoutput : text.g
-                  generate text.g -little > littleoutput
-
-     Here we assume the hypothetical program 'generate' makes two types
-     of output, one if given '-big' and one if given '-little'.  *Note
-     Functions for String Substitution and Analysis: Text Functions, for
-     an explanation of the 'subst' function.
-
-   Suppose you would like to vary the prerequisites according to the
-target, much as the variable '$@' allows you to vary the recipe.  You
-cannot do this with multiple targets in an ordinary rule, but you can do
-it with a "static pattern rule".  *Note Static Pattern Rules: Static
-Pattern.
-
-Rules with Grouped Targets
-..........................
-
-If instead of independent targets you have a recipe that generates
-multiple files from a single invocation, you can express that
-relationship by declaring your rule to use _grouped targets_.  A grouped
-target rule uses the separator '&:' (the '&' here is used to imply
-"all").
-
-   When 'make' builds any one of the grouped targets, it understands
-that all the other targets in the group are also created as a result of
-the invocation of the recipe.  Furthermore, if only some of the grouped
-targets are out of date or missing 'make' will realize that running the
-recipe will update all of the targets.
-
-   As an example, this rule defines a grouped target:
-
-     foo bar biz &: baz boz
-             echo $^ > foo
-             echo $^ > bar
-             echo $^ > biz
-
-   During the execution of a grouped target's recipe, the automatic
-variable '$@' is set to the name of the particular target in the group
-which triggered the rule.  Caution must be used if relying on this
-variable in the recipe of a grouped target rule.
-
-   Unlike independent targets, a grouped target rule _must_ include a
-recipe.  However, targets that are members of a grouped target may also
-appear in independent target rule definitions that do not have recipes.
-
-   Each target may have only one recipe associated with it.  If a
-grouped target appears in either an independent target rule or in
-another grouped target rule with a recipe, you will get a warning and
-the latter recipe will replace the former recipe.  Additionally the
-target will be removed from the previous group and appear only in the
-new group.
-
-   If you would like a target to appear in multiple groups, then you
-must use the double-colon grouped target separator, '&::' when declaring
-all of the groups containing that target.  Grouped double-colon targets
-are each considered independently, and each grouped double-colon rule's
-recipe is executed at most once, if at least one of its multiple targets
-requires updating.
-
-

-
-4.11 Multiple Rules for One Target
-==================================
-
-One file can be the target of several rules.  All the prerequisites
-mentioned in all the rules are merged into one list of prerequisites for
-the target.  If the target is older than any prerequisite from any rule,
-the recipe is executed.
-
-   There can only be one recipe to be executed for a file.  If more than
-one rule gives a recipe for the same file, 'make' uses the last one
-given and prints an error message.  (As a special case, if the file's
-name begins with a dot, no error message is printed.  This odd behavior
-is only for compatibility with other implementations of 'make'... you
-should avoid using it).  Occasionally it is useful to have the same
-target invoke multiple recipes which are defined in different parts of
-your makefile; you can use "double-colon rules" (*note Double-Colon::)
-for this.
-
-   An extra rule with just prerequisites can be used to give a few extra
-prerequisites to many files at once.  For example, makefiles often have
-a variable, such as 'objects', containing a list of all the compiler
-output files in the system being made.  An easy way to say that all of
-them must be recompiled if 'config.h' changes is to write the following:
-
-     objects = foo.o bar.o
-     foo.o : defs.h
-     bar.o : defs.h test.h
-     $(objects) : config.h
-
-   This could be inserted or taken out without changing the rules that
-really specify how to make the object files, making it a convenient form
-to use if you wish to add the additional prerequisite intermittently.
-
-   Another wrinkle is that the additional prerequisites could be
-specified with a variable that you set with a command line argument to
-'make' (*note Overriding Variables: Overriding.).  For example,
-
-     extradeps=
-     $(objects) : $(extradeps)
-
-means that the command 'make extradeps=foo.h' will consider 'foo.h' as a
-prerequisite of each object file, but plain 'make' will not.
-
-   If none of the explicit rules for a target has a recipe, then 'make'
-searches for an applicable implicit rule to find one *note Using
-Implicit Rules: Implicit Rules.).

-
-4.12 Static Pattern Rules
-=========================
-
-"Static pattern rules" are rules which specify multiple targets and
-construct the prerequisite names for each target based on the target
-name.  They are more general than ordinary rules with multiple targets
-because the targets do not have to have identical prerequisites.  Their
-prerequisites must be _analogous_, but not necessarily _identical_.

-
-4.12.1 Syntax of Static Pattern Rules
--------------------------------------
-
-Here is the syntax of a static pattern rule:
-
-     TARGETS ...: TARGET-PATTERN: PREREQ-PATTERNS ...
-             RECIPE
-             ...
-
-The TARGETS list specifies the targets that the rule applies to.  The
-targets can contain wildcard characters, just like the targets of
-ordinary rules (*note Using Wildcard Characters in File Names:
-Wildcards.).
-
-   The TARGET-PATTERN and PREREQ-PATTERNS say how to compute the
-prerequisites of each target.  Each target is matched against the
-TARGET-PATTERN to extract a part of the target name, called the "stem".
-This stem is substituted into each of the PREREQ-PATTERNS to make the
-prerequisite names (one from each PREREQ-PATTERN).
-
-   Each pattern normally contains the character '%' just once.  When the
-TARGET-PATTERN matches a target, the '%' can match any part of the
-target name; this part is called the "stem".  The rest of the pattern
-must match exactly.  For example, the target 'foo.o' matches the pattern
-'%.o', with 'foo' as the stem.  The targets 'foo.c' and 'foo.out' do not
-match that pattern.
-
-   The prerequisite names for each target are made by substituting the
-stem for the '%' in each prerequisite pattern.  For example, if one
-prerequisite pattern is '%.c', then substitution of the stem 'foo' gives
-the prerequisite name 'foo.c'.  It is legitimate to write a prerequisite
-pattern that does not contain '%'; then this prerequisite is the same
-for all targets.
-
-   '%' characters in pattern rules can be quoted with preceding
-backslashes ('\').  Backslashes that would otherwise quote '%'
-characters can be quoted with more backslashes.  Backslashes that quote
-'%' characters or other backslashes are removed from the pattern before
-it is compared to file names or has a stem substituted into it.
-Backslashes that are not in danger of quoting '%' characters go
-unmolested.  For example, the pattern 'the\%weird\\%pattern\\' has
-'the%weird\' preceding the operative '%' character, and 'pattern\\'
-following it.  The final two backslashes are left alone because they
-cannot affect any '%' character.
-
-   Here is an example, which compiles each of 'foo.o' and 'bar.o' from
-the corresponding '.c' file:
-
-     objects = foo.o bar.o
-
-     all: $(objects)
-
-     $(objects): %.o: %.c
-             $(CC) -c $(CFLAGS) $< -o $@
-
-Here '$<' is the automatic variable that holds the name of the
-prerequisite and '$@' is the automatic variable that holds the name of
-the target; see *note Automatic Variables::.
-
-   Each target specified must match the target pattern; a warning is
-issued for each target that does not.  If you have a list of files, only
-some of which will match the pattern, you can use the 'filter' function
-to remove non-matching file names (*note Functions for String
-Substitution and Analysis: Text Functions.):
-
-     files = foo.elc bar.o lose.o
-
-     $(filter %.o,$(files)): %.o: %.c
-             $(CC) -c $(CFLAGS) $< -o $@
-     $(filter %.elc,$(files)): %.elc: %.el
-             emacs -f batch-byte-compile $<
-
-In this example the result of '$(filter %.o,$(files))' is 'bar.o
-lose.o', and the first static pattern rule causes each of these object
-files to be updated by compiling the corresponding C source file.  The
-result of '$(filter %.elc,$(files))' is 'foo.elc', so that file is made
-from 'foo.el'.
-
-   Another example shows how to use '$*' in static pattern rules:
-
-     bigoutput littleoutput : %output : text.g
-             generate text.g -$* > $@
-
-When the 'generate' command is run, '$*' will expand to the stem, either
-'big' or 'little'.

-
-4.12.2 Static Pattern Rules versus Implicit Rules
--------------------------------------------------
-
-A static pattern rule has much in common with an implicit rule defined
-as a pattern rule (*note Defining and Redefining Pattern Rules: Pattern
-Rules.).  Both have a pattern for the target and patterns for
-constructing the names of prerequisites.  The difference is in how
-'make' decides _when_ the rule applies.
-
-   An implicit rule _can_ apply to any target that matches its pattern,
-but it _does_ apply only when the target has no recipe otherwise
-specified, and only when the prerequisites can be found.  If more than
-one implicit rule appears applicable, only one applies; the choice
-depends on the order of rules.
-
-   By contrast, a static pattern rule applies to the precise list of
-targets that you specify in the rule.  It cannot apply to any other
-target and it invariably does apply to each of the targets specified.
-If two conflicting rules apply, and both have recipes, that's an error.
-
-   The static pattern rule can be better than an implicit rule for these
-reasons:
-
-   * You may wish to override the usual implicit rule for a few files
-     whose names cannot be categorized syntactically but can be given in
-     an explicit list.
-
-   * If you cannot be sure of the precise contents of the directories
-     you are using, you may not be sure which other irrelevant files
-     might lead 'make' to use the wrong implicit rule.  The choice might
-     depend on the order in which the implicit rule search is done.
-     With static pattern rules, there is no uncertainty: each rule
-     applies to precisely the targets specified.

-
-4.13 Double-Colon Rules
-=======================
-
-"Double-colon" rules are explicit rules written with '::' instead of ':'
-after the target names.  They are handled differently from ordinary
-rules when the same target appears in more than one rule.  Pattern rules
-with double-colons have an entirely different meaning (*note
-Match-Anything Rules::).
-
-   When a target appears in multiple rules, all the rules must be the
-same type: all ordinary, or all double-colon.  If they are double-colon,
-each of them is independent of the others.  Each double-colon rule's
-recipe is executed if the target is older than any prerequisites of that
-rule.  If there are no prerequisites for that rule, its recipe is always
-executed (even if the target already exists).  This can result in
-executing none, any, or all of the double-colon rules.
-
-   Double-colon rules with the same target are in fact completely
-separate from one another.  Each double-colon rule is processed
-individually, just as rules with different targets are processed.
-
-   The double-colon rules for a target are executed in the order they
-appear in the makefile.  However, the cases where double-colon rules
-really make sense are those where the order of executing the recipes
-would not matter.
-
-   Double-colon rules are somewhat obscure and not often very useful;
-they provide a mechanism for cases in which the method used to update a
-target differs depending on which prerequisite files caused the update,
-and such cases are rare.
-
-   Each double-colon rule should specify a recipe; if it does not, an
-implicit rule will be used if one applies.  *Note Using Implicit Rules:
-Implicit Rules.

-
-4.14 Generating Prerequisites Automatically
-===========================================
-
-In the makefile for a program, many of the rules you need to write often
-say only that some object file depends on some header file.  For
-example, if 'main.c' uses 'defs.h' via an '#include', you would write:
-
-     main.o: defs.h
-
-You need this rule so that 'make' knows that it must remake 'main.o'
-whenever 'defs.h' changes.  You can see that for a large program you
-would have to write dozens of such rules in your makefile.  And, you
-must always be very careful to update the makefile every time you add or
-remove an '#include'.
-
-   To avoid this hassle, most modern C compilers can write these rules
-for you, by looking at the '#include' lines in the source files.
-Usually this is done with the '-M' option to the compiler.  For example,
-the command:
-
-     cc -M main.c
-
-generates the output:
-
-     main.o : main.c defs.h
-
-Thus you no longer have to write all those rules yourself.  The compiler
-will do it for you.
-
-   Note that such a rule constitutes mentioning 'main.o' in a makefile,
-so it can never be considered an intermediate file by implicit rule
-search.  This means that 'make' won't ever remove the file after using
-it; *note Chains of Implicit Rules: Chained Rules.
-
-   With old 'make' programs, it was traditional practice to use this
-compiler feature to generate prerequisites on demand with a command like
-'make depend'.  That command would create a file 'depend' containing all
-the automatically-generated prerequisites; then the makefile could use
-'include' to read them in (*note Include::).
-
-   In GNU 'make', the feature of remaking makefiles makes this practice
-obsolete--you need never tell 'make' explicitly to regenerate the
-prerequisites, because it always regenerates any makefile that is out of
-date.  *Note Remaking Makefiles::.
-
-   The practice we recommend for automatic prerequisite generation is to
-have one makefile corresponding to each source file.  For each source
-file 'NAME.c' there is a makefile 'NAME.d' which lists what files the
-object file 'NAME.o' depends on.  That way only the source files that
-have changed need to be rescanned to produce the new prerequisites.
-
-   Here is the pattern rule to generate a file of prerequisites (i.e., a
-makefile) called 'NAME.d' from a C source file called 'NAME.c':
-
-     %.d: %.c
-             @set -e; rm -f $@; \
-              $(CC) -M $(CPPFLAGS) $< > $@.$$$$; \
-              sed 's,\($*\)\.o[ :]*,\1.o $@ : ,g' < $@.$$$$ > $@; \
-              rm -f $@.$$$$
-
-*Note Pattern Rules::, for information on defining pattern rules.  The
-'-e' flag to the shell causes it to exit immediately if the '$(CC)'
-command (or any other command) fails (exits with a nonzero status).
-
-   With the GNU C compiler, you may wish to use the '-MM' flag instead
-of '-M'.  This omits prerequisites on system header files.  *Note
-Options Controlling the Preprocessor: (gcc)Preprocessor Options, for
-details.
-
-   The purpose of the 'sed' command is to translate (for example):
-
-     main.o : main.c defs.h
-
-into:
-
-     main.o main.d : main.c defs.h
-
-This makes each '.d' file depend on all the source and header files that
-the corresponding '.o' file depends on.  'make' then knows it must
-regenerate the prerequisites whenever any of the source or header files
-changes.
-
-   Once you've defined the rule to remake the '.d' files, you then use
-the 'include' directive to read them all in.  *Note Include::.  For
-example:
-
-     sources = foo.c bar.c
-
-     include $(sources:.c=.d)
-
-(This example uses a substitution variable reference to translate the
-list of source files 'foo.c bar.c' into a list of prerequisite
-makefiles, 'foo.d bar.d'.  *Note Substitution Refs::, for full
-information on substitution references.)  Since the '.d' files are
-makefiles like any others, 'make' will remake them as necessary with no
-further work from you.  *Note Remaking Makefiles::.
-
-   Note that the '.d' files contain target definitions; you should be
-sure to place the 'include' directive _after_ the first, default goal in
-your makefiles or run the risk of having a random object file become the
-default goal.  *Note How Make Works::.

-5 Writing Recipes in Rules

-5.1 Recipe Syntax
-=================
-
-Makefiles have the unusual property that there are really two distinct
-syntaxes in one file.  Most of the makefile uses 'make' syntax (*note
-Writing Makefiles: Makefiles.).  However, recipes are meant to be
-interpreted by the shell and so they are written using shell syntax.
-The 'make' program does not try to understand shell syntax: it performs
-only a very few specific translations on the content of the recipe
-before handing it to the shell.

-   Each line in the recipe must start with a tab (or the first character
-in the value of the '.RECIPEPREFIX' variable; *note Special
-Variables::), except that the first recipe line may be attached to the
-target-and-prerequisites line with a semicolon in between.  _Any_ line
-in the makefile that begins with a tab and appears in a "rule context"

-   Some consequences of these rules include:
-
-   * A blank line that begins with a tab is not blank: it's an empty

-
-   * A comment in a recipe is not a 'make' comment; it will be passed to
-     the shell as-is.  Whether the shell treats it as a comment or not
-     depends on your shell.
-
-   * A variable definition in a "rule context" which is indented by a
-     tab as the first character on the line, will be considered part of
-     a recipe, not a 'make' variable definition, and passed to the

-   * A conditional expression ('ifdef', 'ifeq', etc.  *note Syntax of

-5.1.1 Splitting Recipe Lines
-----------------------------
-
-One of the few ways in which 'make' does interpret recipes is checking
-for a backslash just before the newline.  As in normal makefile syntax,
-a single logical recipe line can be split into multiple physical lines
-in the makefile by placing a backslash before each newline.  A sequence
-of lines like this is considered a single recipe line, and one instance
-of the shell will be invoked to run it.
-
-   However, in contrast to how they are treated in other places in a
-makefile (*note Splitting Long Lines: Splitting Lines.),
-backslash/newline pairs are _not_ removed from the recipe.  Both the
-backslash and the newline characters are preserved and passed to the
-shell.  How the backslash/newline is interpreted depends on your shell.
-If the first character of the next line after the backslash/newline is
-the recipe prefix character (a tab by default; *note Special
-Variables::), then that character (and only that character) is removed.
-Whitespace is never added to the recipe.
-
-   For example, the recipe for the all target in this makefile:
-
-     all :
-             @echo no\
-     space
-             @echo no\
-             space
-             @echo one \
-             space
-             @echo one\
-              space
-
-consists of four separate shell commands where the output is:
-
-     nospace
-     nospace
-     one space
-     one space
-
-   As a more complex example, this makefile:
-
-     all : ; @echo 'hello \
-             world' ; echo "hello \
-         world"
-
-will invoke one shell with a command of:
-
-     echo 'hello \
-     world' ; echo "hello \
-         world"
-
-which, according to shell quoting rules, will yield the following
-output:
-
-     hello \
-     world
-     hello     world
-
-Notice how the backslash/newline pair was removed inside the string
-quoted with double quotes ('"..."'), but not from the string quoted with
-single quotes (''...'').  This is the way the default shell ('/bin/sh')
-handles backslash/newline pairs.  If you specify a different shell in
-your makefiles it may treat them differently.
-
-   Sometimes you want to split a long line inside of single quotes, but
-you don't want the backslash/newline to appear in the quoted content.
-This is often the case when passing scripts to languages such as Perl,
-where extraneous backslashes inside the script can change its meaning or
-even be a syntax error.  One simple way of handling this is to place the
-quoted string, or even the entire command, into a 'make' variable then
-use the variable in the recipe.  In this situation the newline quoting
-rules for makefiles will be used, and the backslash/newline will be
-removed.  If we rewrite our example above using this method:
-
-     HELLO = 'hello \
-     world'
-
-     all : ; @echo $(HELLO)
-
-we will get output like this:
-
-     hello world
-
-   If you like, you can also use target-specific variables (*note
-Target-specific Variable Values: Target-specific.) to obtain a tighter
-correspondence between the variable and the recipe that uses it.

-
-5.1.2 Using Variables in Recipes
---------------------------------
-
-The other way in which 'make' processes recipes is by expanding any
-variable references in them (*note Basics of Variable References:
-Reference.).  This occurs after make has finished reading all the
-makefiles and the target is determined to be out of date; so, the
-recipes for targets which are not rebuilt are never expanded.
-
-   Variable and function references in recipes have identical syntax and
-semantics to references elsewhere in the makefile.  They also have the
-same quoting rules: if you want a dollar sign to appear in your recipe,
-you must double it ('$$').  For shells like the default shell, that use
-dollar signs to introduce variables, it's important to keep clear in
-your mind whether the variable you want to reference is a 'make'
-variable (use a single dollar sign) or a shell variable (use two dollar
-signs).  For example:
-
-     LIST = one two three
-     all:
-             for i in $(LIST); do \
-                 echo $$i; \
-             done
-
-results in the following command being passed to the shell:
-
-     for i in one two three; do \
-         echo $i; \
-     done
-
-which generates the expected result:
-
-     one
-     two
-     three

-
-5.2 Recipe Echoing
-==================
-
-Normally 'make' prints each line of the recipe before it is executed.
-We call this "echoing" because it gives the appearance that you are
-typing the lines yourself.
-
-   When a line starts with '@', the echoing of that line is suppressed.
-The '@' is discarded before the line is passed to the shell.  Typically
-you would use this for a command whose only effect is to print
-something, such as an 'echo' command to indicate progress through the
-makefile:
-
-     @echo About to make distribution files
-
-   When 'make' is given the flag '-n' or '--just-print' it only echoes
-most recipes, without executing them.  *Note Summary of Options: Options
-Summary.  In this case even the recipe lines starting with '@' are
-printed.  This flag is useful for finding out which recipes 'make'
-thinks are necessary without actually doing them.
-
-   The '-s' or '--silent' flag to 'make' prevents all echoing, as if all
-recipes started with '@'.  A rule in the makefile for the special target
-'.SILENT' without prerequisites has the same effect (*note Special
-Built-in Target Names: Special Targets.).
-
-
-File: make.info,  Node: Execution,  Next: Parallel,  Prev: Echoing,  Up: Recipes
-
-5.3 Recipe Execution
-====================
-
-When it is time to execute recipes to update a target, they are executed
-by invoking a new sub-shell for each line of the recipe, unless the
-'.ONESHELL' special target is in effect (*note Using One Shell: One
-Shell.) (In practice, 'make' may take shortcuts that do not affect the
-results.)
-
-   *Please note:* this implies that setting shell variables and invoking
-shell commands such as 'cd' that set a context local to each process
-will not affect the following lines in the recipe.(1)  If you want to
-use 'cd' to affect the next statement, put both statements in a single
-recipe line.  Then 'make' will invoke one shell to run the entire line,
-and the shell will execute the statements in sequence.  For example:
-
-     foo : bar/lose
-             cd $(<D) && gobble $(<F) > ../$@
-
-Here we use the shell AND operator ('&&') so that if the 'cd' command
-fails, the script will fail without trying to invoke the 'gobble'
-command in the wrong directory, which could cause problems (in this case
-it would certainly cause '../foo' to be truncated, at least).

-
-
-File: make.info,  Node: One Shell,  Next: Choosing the Shell,  Prev: Execution,  Up: Execution
-
-5.3.1 Using One Shell
----------------------
-
-Sometimes you would prefer that all the lines in the recipe be passed to
-a single invocation of the shell.  There are generally two situations
-where this is useful: first, it can improve performance in makefiles
-where recipes consist of many command lines, by avoiding extra
-processes.  Second, you might want newlines to be included in your
-recipe command (for example perhaps you are using a very different
-interpreter as your 'SHELL').  If the '.ONESHELL' special target appears
-anywhere in the makefile then _all_ recipe lines for each target will be
-provided to a single invocation of the shell.  Newlines between recipe
-lines will be preserved.  For example:
-
-     .ONESHELL:
-     foo : bar/lose
-             cd $(@D)
-             gobble $(@F) > ../$@
-
-would now work as expected even though the commands are on different
-recipe lines.
-
-   If '.ONESHELL' is provided, then only the first line of the recipe
-will be checked for the special prefix characters ('@', '-', and '+').
-Subsequent lines will include the special characters in the recipe line
-when the 'SHELL' is invoked.  If you want your recipe to start with one
-of these special characters you'll need to arrange for them to not be
-the first characters on the first line, perhaps by adding a comment or
-similar.  For example, this would be a syntax error in Perl because the
-first '@' is removed by make:
-
-     .ONESHELL:
-     SHELL = /usr/bin/perl
-     .SHELLFLAGS = -e
-     show :
-             @f = qw(a b c);
-             print "@f\n";
-
-However, either of these alternatives would work properly:
-
-     .ONESHELL:
-     SHELL = /usr/bin/perl
-     .SHELLFLAGS = -e
-     show :
-             # Make sure "@" is not the first character on the first line
-             @f = qw(a b c);
-             print "@f\n";
-
-or
-
-     .ONESHELL:
-     SHELL = /usr/bin/perl
-     .SHELLFLAGS = -e
-     show :
-             my @f = qw(a b c);
-             print "@f\n";
-
-   As a special feature, if 'SHELL' is determined to be a POSIX-style
-shell, the special prefix characters in "internal" recipe lines will be
-_removed_ before the recipe is processed.  This feature is intended to
-allow existing makefiles to add the '.ONESHELL' special target and still
-run properly without extensive modifications.  Since the special prefix
-characters are not legal at the beginning of a line in a POSIX shell
-script this is not a loss in functionality.  For example, this works as
-expected:
-
-     .ONESHELL:
-     foo : bar/lose
-             @cd $(@D)
-             @gobble $(@F) > ../$@
-
-   Even with this special feature, however, makefiles with '.ONESHELL'
-will behave differently in ways that could be noticeable.  For example,
-normally if any line in the recipe fails, that causes the rule to fail
-and no more recipe lines are processed.  Under '.ONESHELL' a failure of
-any but the final recipe line will not be noticed by 'make'.  You can
-modify '.SHELLFLAGS' to add the '-e' option to the shell which will
-cause any failure anywhere in the command line to cause the shell to
-fail, but this could itself cause your recipe to behave differently.
-Ultimately you may need to harden your recipe lines to allow them to
-work with '.ONESHELL'.
-
-
-File: make.info,  Node: Choosing the Shell,  Prev: One Shell,  Up: Execution
-
-5.3.2 Choosing the Shell
-------------------------
-
-The program used as the shell is taken from the variable 'SHELL'.  If
-this variable is not set in your makefile, the program '/bin/sh' is used
-as the shell.  The argument(s) passed to the shell are taken from the
-variable '.SHELLFLAGS'.  The default value of '.SHELLFLAGS' is '-c'
-normally, or '-ec' in POSIX-conforming mode.
-
-   Unlike most variables, the variable 'SHELL' is never set from the
-environment.  This is because the 'SHELL' environment variable is used
-to specify your personal choice of shell program for interactive use.
-It would be very bad for personal choices like this to affect the
-functioning of makefiles.  *Note Variables from the Environment:
-Environment.
-
-   Furthermore, when you do set 'SHELL' in your makefile that value is
-_not_ exported in the environment to recipe lines that 'make' invokes.
-Instead, the value inherited from the user's environment, if any, is
-exported.  You can override this behavior by explicitly exporting
-'SHELL' (*note Communicating Variables to a Sub-'make':
-Variables/Recursion.), forcing it to be passed in the environment to
-recipe lines.
-
-   However, on MS-DOS and MS-Windows the value of 'SHELL' in the
-environment *is* used, since on those systems most users do not set this
-variable, and therefore it is most likely set specifically to be used by
-'make'.  On MS-DOS, if the setting of 'SHELL' is not suitable for
-'make', you can set the variable 'MAKESHELL' to the shell that 'make'
-should use; if set it will be used as the shell instead of the value of
-'SHELL'.
-
-Choosing a Shell in DOS and Windows
-...................................
-
-Choosing a shell in MS-DOS and MS-Windows is much more complex than on
-other systems.
-
-   On MS-DOS, if 'SHELL' is not set, the value of the variable 'COMSPEC'
-(which is always set) is used instead.
-
-   The processing of lines that set the variable 'SHELL' in Makefiles is
-different on MS-DOS. The stock shell, 'command.com', is ridiculously
-limited in its functionality and many users of 'make' tend to install a
-replacement shell.  Therefore, on MS-DOS, 'make' examines the value of
-'SHELL', and changes its behavior based on whether it points to a
-Unix-style or DOS-style shell.  This allows reasonable functionality
-even if 'SHELL' points to 'command.com'.
-
-   If 'SHELL' points to a Unix-style shell, 'make' on MS-DOS
-additionally checks whether that shell can indeed be found; if not, it
-ignores the line that sets 'SHELL'.  In MS-DOS, GNU 'make' searches for
-the shell in the following places:
-
-  1. In the precise place pointed to by the value of 'SHELL'.  For
-     example, if the makefile specifies 'SHELL = /bin/sh', 'make' will
-     look in the directory '/bin' on the current drive.
-
-  2. In the current directory.
-
-  3. In each of the directories in the 'PATH' variable, in order.
-
-   In every directory it examines, 'make' will first look for the
-specific file ('sh' in the example above).  If this is not found, it
-will also look in that directory for that file with one of the known
-extensions which identify executable files.  For example '.exe', '.com',
-'.bat', '.btm', '.sh', and some others.
-
-   If any of these attempts is successful, the value of 'SHELL' will be
-set to the full pathname of the shell as found.  However, if none of
-these is found, the value of 'SHELL' will not be changed, and thus the
-line that sets it will be effectively ignored.  This is so 'make' will
-only support features specific to a Unix-style shell if such a shell is
-actually installed on the system where 'make' runs.
-
-   Note that this extended search for the shell is limited to the cases
-where 'SHELL' is set from the Makefile; if it is set in the environment
-or command line, you are expected to set it to the full pathname of the
-shell, exactly as things are on Unix.
-
-   The effect of the above DOS-specific processing is that a Makefile
-that contains 'SHELL = /bin/sh' (as many Unix makefiles do), will work
-on MS-DOS unaltered if you have e.g. 'sh.exe' installed in some
-directory along your 'PATH'.

-
-5.4 Parallel Execution
-======================
-
-GNU 'make' knows how to execute several recipes at once.  Normally,
-'make' will execute only one recipe at a time, waiting for it to finish
-before executing the next.  However, the '-j' or '--jobs' option tells
-'make' to execute many recipes simultaneously.  You can inhibit
-parallelism in a particular makefile with the '.NOTPARALLEL'
-pseudo-target (*note Special Built-in Target Names: Special Targets.).
-
-   On MS-DOS, the '-j' option has no effect, since that system doesn't
-support multi-processing.
-
-   If the '-j' option is followed by an integer, this is the number of
-recipes to execute at once; this is called the number of "job slots".
-If there is nothing looking like an integer after the '-j' option, there
-is no limit on the number of job slots.  The default number of job slots
-is one, which means serial execution (one thing at a time).
-
-   Handling recursive 'make' invocations raises issues for parallel
-execution.  For more information on this, see *note Communicating
-Options to a Sub-'make': Options/Recursion.
-
-   If a recipe fails (is killed by a signal or exits with a nonzero
-status), and errors are not ignored for that recipe (*note Errors in
-Recipes: Errors.), the remaining recipe lines to remake the same target
-will not be run.  If a recipe fails and the '-k' or '--keep-going'
-option was not given (*note Summary of Options: Options Summary.),
-'make' aborts execution.  If make terminates for any reason (including a
-signal) with child processes running, it waits for them to finish before
-actually exiting.
-
-   When the system is heavily loaded, you will probably want to run
-fewer jobs than when it is lightly loaded.  You can use the '-l' option
-to tell 'make' to limit the number of jobs to run at once, based on the
-load average.  The '-l' or '--max-load' option is followed by a
-floating-point number.  For example,
-
-     -l 2.5
-
-will not let 'make' start more than one job if the load average is above
-2.5.  The '-l' option with no following number removes the load limit,
-if one was given with a previous '-l' option.
-
-   More precisely, when 'make' goes to start up a job, and it already
-has at least one job running, it checks the current load average; if it
-is not lower than the limit given with '-l', 'make' waits until the load
-average goes below that limit, or until all the other jobs finish.
-
-   By default, there is no load limit.

-5.4.1 Output During Parallel Execution
---------------------------------------
-
-When running several recipes in parallel the output from each recipe
-appears as soon as it is generated, with the result that messages from
-different recipes may be interspersed, sometimes even appearing on the
-same line.  This can make reading the output very difficult.
-
-   To avoid this you can use the '--output-sync' ('-O') option.  This
-option instructs 'make' to save the output from the commands it invokes
-and print it all once the commands are completed.  Additionally, if
-there are multiple recursive 'make' invocations running in parallel,
-they will communicate so that only one of them is generating output at a
-time.
-
-   If working directory printing is enabled (*note The
-'--print-directory' Option: -w Option.), the enter/leave messages are
-printed around each output grouping.  If you prefer not to see these
-messages add the '--no-print-directory' option to 'MAKEFLAGS'.
-
-   There are four levels of granularity when synchronizing output,
-specified by giving an argument to the option (e.g., '-Oline' or
-'--output-sync=recurse').
-
-'none'
-     This is the default: all output is sent directly as it is generated
-     and no synchronization is performed.
-
-'line'
-     Output from each individual line of the recipe is grouped and
-     printed as soon as that line is complete.  If a recipe consists of
-     multiple lines, they may be interspersed with lines from other
-     recipes.
-
-'target'
-     Output from the entire recipe for each target is grouped and
-     printed once the target is complete.  This is the default if the
-     '--output-sync' or '-O' option is given with no argument.
-
-'recurse'
-     Output from each recursive invocation of 'make' is grouped and
-     printed once the recursive invocation is complete.
-
-   Regardless of the mode chosen, the total build time will be the same.
-The only difference is in how the output appears.
-
-   The 'target' and 'recurse' modes both collect the output of the
-entire recipe of a target and display it uninterrupted when the recipe
-completes.  The difference between them is in how recipes that contain
-recursive invocations of 'make' are treated (*note Recursive Use of
-'make': Recursion.).  For all recipes which have no recursive lines, the
-'target' and 'recurse' modes behave identically.
-
-   If the 'recurse' mode is chosen, recipes that contain recursive
-'make' invocations are treated the same as other targets: the output
-from the recipe, including the output from the recursive 'make', is
-saved and printed after the entire recipe is complete.  This ensures
-output from all the targets built by a given recursive 'make' instance
-are grouped together, which may make the output easier to understand.
-However it also leads to long periods of time during the build where no
-output is seen, followed by large bursts of output.  If you are not
-watching the build as it proceeds, but instead viewing a log of the
-build after the fact, this may be the best option for you.
-
-   If you are watching the output, the long gaps of quiet during the
-build can be frustrating.  The 'target' output synchronization mode
-detects when 'make' is going to be invoked recursively, using the
-standard methods, and it will not synchronize the output of those lines.
-The recursive 'make' will perform the synchronization for its targets
-and the output from each will be displayed immediately when it
-completes.  Be aware that output from recursive lines of the recipe are
-not synchronized (for example if the recursive line prints a message
-before running 'make', that message will not be synchronized).
-
-   The 'line' mode can be useful for front-ends that are watching the
-output of 'make' to track when recipes are started and completed.
-
-   Some programs invoked by 'make' may behave differently if they
-determine they're writing output to a terminal versus a file (often
-described as "interactive" vs.  "non-interactive" modes).  For example,
-many programs that can display colorized output will not do so if they
-determine they are not writing to a terminal.  If your makefile invokes
-a program like this then using the output synchronization options will
-cause the program to believe it's running in "non-interactive" mode even
-though the output will ultimately go to the terminal.

-
-5.4.2 Input During Parallel Execution
--------------------------------------
-
-Two processes cannot both take input from the same device at the same
-time.  To make sure that only one recipe tries to take input from the
-terminal at once, 'make' will invalidate the standard input streams of
-all but one running recipe.  If another recipe attempts to read from
-standard input it will usually incur a fatal error (a 'Broken pipe'
-signal).
-
-   It is unpredictable which recipe will have a valid standard input
-stream (which will come from the terminal, or wherever you redirect the
-standard input of 'make').  The first recipe run will always get it
-first, and the first recipe started after that one finishes will get it
-next, and so on.
-
-   We will change how this aspect of 'make' works if we find a better
-alternative.  In the mean time, you should not rely on any recipe using
-standard input at all if you are using the parallel execution feature;
-but if you are not using this feature, then standard input works
-normally in all recipes.

-
-5.5 Errors in Recipes
-=====================
-
-After each shell invocation returns, 'make' looks at its exit status.
-If the shell completed successfully (the exit status is zero), the next
-line in the recipe is executed in a new shell; after the last line is
-finished, the rule is finished.
-
-   If there is an error (the exit status is nonzero), 'make' gives up on
-the current rule, and perhaps on all rules.
-
-   Sometimes the failure of a certain recipe line does not indicate a
-problem.  For example, you may use the 'mkdir' command to ensure that a
-directory exists.  If the directory already exists, 'mkdir' will report
-an error, but you probably want 'make' to continue regardless.
-
-   To ignore errors in a recipe line, write a '-' at the beginning of
-the line's text (after the initial tab).  The '-' is discarded before
-the line is passed to the shell for execution.
-
-   For example,
-
-     clean:
-             -rm -f *.o
-
-This causes 'make' to continue even if 'rm' is unable to remove a file.
-
-   When you run 'make' with the '-i' or '--ignore-errors' flag, errors
-are ignored in all recipes of all rules.  A rule in the makefile for the
-special target '.IGNORE' has the same effect, if there are no
-prerequisites.  This is less flexible but sometimes useful.
-
-   When errors are to be ignored, because of either a '-' or the '-i'
-flag, 'make' treats an error return just like success, except that it
-prints out a message that tells you the status code the shell exited
-with, and says that the error has been ignored.
-
-   When an error happens that 'make' has not been told to ignore, it
-implies that the current target cannot be correctly remade, and neither
-can any other that depends on it either directly or indirectly.  No
-further recipes will be executed for these targets, since their
-preconditions have not been achieved.
-
-   Normally 'make' gives up immediately in this circumstance, returning
-a nonzero status.  However, if the '-k' or '--keep-going' flag is
-specified, 'make' continues to consider the other prerequisites of the
-pending targets, remaking them if necessary, before it gives up and
-returns nonzero status.  For example, after an error in compiling one
-object file, 'make -k' will continue compiling other object files even
-though it already knows that linking them will be impossible.  *Note
-Summary of Options: Options Summary.
-
-   The usual behavior assumes that your purpose is to get the specified
-targets up to date; once 'make' learns that this is impossible, it might
-as well report the failure immediately.  The '-k' option says that the
-real purpose is to test as many of the changes made in the program as
-possible, perhaps to find several independent problems so that you can
-correct them all before the next attempt to compile.  This is why Emacs'
-'compile' command passes the '-k' flag by default.
-
-   Usually when a recipe line fails, if it has changed the target file
-at all, the file is corrupted and cannot be used--or at least it is not
-completely updated.  Yet the file's time stamp says that it is now up to
-date, so the next time 'make' runs, it will not try to update that file.
-The situation is just the same as when the shell is killed by a signal;
-*note Interrupts::.  So generally the right thing to do is to delete the
-target file if the recipe fails after beginning to change the file.
-'make' will do this if '.DELETE_ON_ERROR' appears as a target.  This is
-almost always what you want 'make' to do, but it is not historical
-practice; so for compatibility, you must explicitly request it.

-
-5.6 Interrupting or Killing 'make'
-==================================
-
-If 'make' gets a fatal signal while a shell is executing, it may delete
-the target file that the recipe was supposed to update.  This is done if
-the target file's last-modification time has changed since 'make' first
-checked it.
-
-   The purpose of deleting the target is to make sure that it is remade
-from scratch when 'make' is next run.  Why is this?  Suppose you type
-'Ctrl-c' while a compiler is running, and it has begun to write an
-object file 'foo.o'.  The 'Ctrl-c' kills the compiler, resulting in an
-incomplete file whose last-modification time is newer than the source
-file 'foo.c'.  But 'make' also receives the 'Ctrl-c' signal and deletes
-this incomplete file.  If 'make' did not do this, the next invocation of
-'make' would think that 'foo.o' did not require updating--resulting in a
-strange error message from the linker when it tries to link an object
-file half of which is missing.
-
-   You can prevent the deletion of a target file in this way by making
-the special target '.PRECIOUS' depend on it.  Before remaking a target,
-'make' checks to see whether it appears on the prerequisites of
-'.PRECIOUS', and thereby decides whether the target should be deleted if
-a signal happens.  Some reasons why you might do this are that the
-target is updated in some atomic fashion, or exists only to record a
-modification-time (its contents do not matter), or must exist at all
-times to prevent other sorts of trouble.
-
-   Although 'make' does its best to clean up there are certain
-situations in which cleanup is impossible.  For example, 'make' may be
-killed by an uncatchable signal.  Or, one of the programs make invokes
-may be killed or crash, leaving behind an up-to-date but corrupt target
-file: 'make' will not realize that this failure requires the target to
-be cleaned.  Or 'make' itself may encounter a bug and crash.
-
-   For these reasons it's best to write _defensive recipes_, which won't
-leave behind corrupted targets even if they fail.  Most commonly these
-recipes create temporary files rather than updating the target directly,
-then rename the temporary file to the final target name.  Some compilers
-already behave this way, so that you don't need to write a defensive
-recipe.

-5.7 Recursive Use of 'make'
-===========================
-
-Recursive use of 'make' means using 'make' as a command in a makefile.
-This technique is useful when you want separate makefiles for various
-subsystems that compose a larger system.  For example, suppose you have
-a sub-directory 'subdir' which has its own makefile, and you would like
-the containing directory's makefile to run 'make' on the sub-directory.
-You can do it by writing this:
-
-     subsystem:
-             cd subdir && $(MAKE)
-
-or, equivalently, this (*note Summary of Options: Options Summary.):
-
-     subsystem:
-             $(MAKE) -C subdir
-
-   You can write recursive 'make' commands just by copying this example,
-but there are many things to know about how they work and why, and about
-how the sub-'make' relates to the top-level 'make'.  You may also find
-it useful to declare targets that invoke recursive 'make' commands as
-'.PHONY' (for more discussion on when this is useful, see *note Phony
-Targets::).
-
-   For your convenience, when GNU 'make' starts (after it has processed
-any '-C' options) it sets the variable 'CURDIR' to the pathname of the
-current working directory.  This value is never touched by 'make' again:
-in particular note that if you include files from other directories the
-value of 'CURDIR' does not change.  The value has the same precedence it
-would have if it were set in the makefile (by default, an environment
-variable 'CURDIR' will not override this value).  Note that setting this
-variable has no impact on the operation of 'make' (it does not cause
-'make' to change its working directory, for example).

-
-5.7.1 How the 'MAKE' Variable Works
------------------------------------
-
-Recursive 'make' commands should always use the variable 'MAKE', not the
-explicit command name 'make', as shown here:
-
-     subsystem:
-             cd subdir && $(MAKE)
-
-   The value of this variable is the file name with which 'make' was
-invoked.  If this file name was '/bin/make', then the recipe executed is
-'cd subdir && /bin/make'.  If you use a special version of 'make' to run
-the top-level makefile, the same special version will be executed for
-recursive invocations.
-
-   As a special feature, using the variable 'MAKE' in the recipe of a
-rule alters the effects of the '-t' ('--touch'), '-n' ('--just-print'),
-or '-q' ('--question') option.  Using the 'MAKE' variable has the same
-effect as using a '+' character at the beginning of the recipe line.
-*Note Instead of Executing the Recipes: Instead of Execution.  This
-special feature is only enabled if the 'MAKE' variable appears directly
-in the recipe: it does not apply if the 'MAKE' variable is referenced
-through expansion of another variable.  In the latter case you must use
-the '+' token to get these special effects.
-
-   Consider the command 'make -t' in the above example.  (The '-t'
-option marks targets as up to date without actually running any recipes;
-see *note Instead of Execution::.)  Following the usual definition of
-'-t', a 'make -t' command in the example would create a file named
-'subsystem' and do nothing else.  What you really want it to do is run
-'cd subdir && make -t'; but that would require executing the recipe, and
-'-t' says not to execute recipes.
-
-   The special feature makes this do what you want: whenever a recipe
-line of a rule contains the variable 'MAKE', the flags '-t', '-n' and
-'-q' do not apply to that line.  Recipe lines containing 'MAKE' are
-executed normally despite the presence of a flag that causes most
-recipes not to be run.  The usual 'MAKEFLAGS' mechanism passes the flags
-to the sub-'make' (*note Communicating Options to a Sub-'make':
-Options/Recursion.), so your request to touch the files, or print the
-recipes, is propagated to the subsystem.

-
-5.7.2 Communicating Variables to a Sub-'make'
----------------------------------------------
-
-Variable values of the top-level 'make' can be passed to the sub-'make'
-through the environment by explicit request.  These variables are
-defined in the sub-'make' as defaults, but they do not override
-variables defined in the makefile used by the sub-'make' unless you use
-the '-e' switch (*note Summary of Options: Options Summary.).
-
-   To pass down, or "export", a variable, 'make' adds the variable and
-its value to the environment for running each line of the recipe.  The
-sub-'make', in turn, uses the environment to initialize its table of
-variable values.  *Note Variables from the Environment: Environment.
-
-   Except by explicit request, 'make' exports a variable only if it is
-either defined in the environment initially or set on the command line,
-and if its name consists only of letters, numbers, and underscores.
-Some shells cannot cope with environment variable names consisting of
-characters other than letters, numbers, and underscores.
-
-   The value of the 'make' variable 'SHELL' is not exported.  Instead,
-the value of the 'SHELL' variable from the invoking environment is
-passed to the sub-'make'.  You can force 'make' to export its value for
-'SHELL' by using the 'export' directive, described below.  *Note
-Choosing the Shell::.
-
-   The special variable 'MAKEFLAGS' is always exported (unless you
-unexport it).  'MAKEFILES' is exported if you set it to anything.
-
-   'make' automatically passes down variable values that were defined on
-the command line, by putting them in the 'MAKEFLAGS' variable.  *Note
-Options/Recursion::.
-
-   Variables are _not_ normally passed down if they were created by
-default by 'make' (*note Variables Used by Implicit Rules: Implicit
-Variables.).  The sub-'make' will define these for itself.
-
-   If you want to export specific variables to a sub-'make', use the
-'export' directive, like this:
-
-     export VARIABLE ...
-
-If you want to _prevent_ a variable from being exported, use the
-'unexport' directive, like this:
-
-     unexport VARIABLE ...
-
-In both of these forms, the arguments to 'export' and 'unexport' are
-expanded, and so could be variables or functions which expand to a (list
-of) variable names to be (un)exported.
-
-   As a convenience, you can define a variable and export it at the same
-time by doing:
-
-     export VARIABLE = value
-
-has the same result as:
-
-     VARIABLE = value
-     export VARIABLE
-
-and
-
-     export VARIABLE := value
-
-has the same result as:
-
-     VARIABLE := value
-     export VARIABLE
-
-   Likewise,
-
-     export VARIABLE += value
-
-is just like:
-
-     VARIABLE += value
-     export VARIABLE
-
-*Note Appending More Text to Variables: Appending.
-
-   You may notice that the 'export' and 'unexport' directives work in
-'make' in the same way they work in the shell, 'sh'.
-
-   If you want all variables to be exported by default, you can use
-'export' by itself:
-
-     export
-
-This tells 'make' that variables which are not explicitly mentioned in
-an 'export' or 'unexport' directive should be exported.  Any variable
-given in an 'unexport' directive will still _not_ be exported.  If you
-use 'export' by itself to export variables by default, variables whose
-names contain characters other than alphanumerics and underscores will
-not be exported unless specifically mentioned in an 'export' directive.
-
-   The behavior elicited by an 'export' directive by itself was the
-default in older versions of GNU 'make'.  If your makefiles depend on
-this behavior and you want to be compatible with old versions of 'make',
-you can write a rule for the special target '.EXPORT_ALL_VARIABLES'
-instead of using the 'export' directive.  This will be ignored by old
-'make's, while the 'export' directive will cause a syntax error.
-
-   Likewise, you can use 'unexport' by itself to tell 'make' _not_ to
-export variables by default.  Since this is the default behavior, you
-would only need to do this if 'export' had been used by itself earlier
-(in an included makefile, perhaps).  You *cannot* use 'export' and
-'unexport' by themselves to have variables exported for some recipes and
-not for others.  The last 'export' or 'unexport' directive that appears
-by itself determines the behavior for the entire run of 'make'.
-
-   As a special feature, the variable 'MAKELEVEL' is changed when it is
-passed down from level to level.  This variable's value is a string
-which is the depth of the level as a decimal number.  The value is '0'
-for the top-level 'make'; '1' for a sub-'make', '2' for a
-sub-sub-'make', and so on.  The incrementation happens when 'make' sets
-up the environment for a recipe.
-
-   The main use of 'MAKELEVEL' is to test it in a conditional directive
-(*note Conditional Parts of Makefiles: Conditionals.); this way you can
-write a makefile that behaves one way if run recursively and another way
-if run directly by you.
-
-   You can use the variable 'MAKEFILES' to cause all sub-'make' commands
-to use additional makefiles.  The value of 'MAKEFILES' is a
-whitespace-separated list of file names.  This variable, if defined in
-the outer-level makefile, is passed down through the environment; then
-it serves as a list of extra makefiles for the sub-'make' to read before
-the usual or specified ones.  *Note The Variable 'MAKEFILES': MAKEFILES
-Variable.

-
-5.7.3 Communicating Options to a Sub-'make'
--------------------------------------------
-
-Flags such as '-s' and '-k' are passed automatically to the sub-'make'
-through the variable 'MAKEFLAGS'.  This variable is set up automatically
-by 'make' to contain the flag letters that 'make' received.  Thus, if
-you do 'make -ks' then 'MAKEFLAGS' gets the value 'ks'.
-
-   As a consequence, every sub-'make' gets a value for 'MAKEFLAGS' in
-its environment.  In response, it takes the flags from that value and
-processes them as if they had been given as arguments.  *Note Summary of
-Options: Options Summary.
-
-   Likewise variables defined on the command line are passed to the
-sub-'make' through 'MAKEFLAGS'.  Words in the value of 'MAKEFLAGS' that
-contain '=', 'make' treats as variable definitions just as if they
-appeared on the command line.  *Note Overriding Variables: Overriding.
-
-   The options '-C', '-f', '-o', and '-W' are not put into 'MAKEFLAGS';
-these options are not passed down.
-
-   The '-j' option is a special case (*note Parallel Execution:
-Parallel.).  If you set it to some numeric value 'N' and your operating
-system supports it (most any UNIX system will; others typically won't),
-the parent 'make' and all the sub-'make's will communicate to ensure
-that there are only 'N' jobs running at the same time between them all.
-Note that any job that is marked recursive (*note Instead of Executing
-Recipes: Instead of Execution.) doesn't count against the total jobs
-(otherwise we could get 'N' sub-'make's running and have no slots left
-over for any real work!)
-
-   If your operating system doesn't support the above communication,
-then no '-j' is added to 'MAKEFLAGS', so that sub-'make's run in
-non-parallel mode.  If the '-j' option were passed down to sub-'make's
-you would get many more jobs running in parallel than you asked for.  If
-you give '-j' with no numeric argument, meaning to run as many jobs as
-possible in parallel, this is passed down, since multiple infinities are
-no more than one.
-
-   If you do not want to pass the other flags down, you must change the
-value of 'MAKEFLAGS', like this:
-
-     subsystem:
-             cd subdir && $(MAKE) MAKEFLAGS=
-
-   The command line variable definitions really appear in the variable
-'MAKEOVERRIDES', and 'MAKEFLAGS' contains a reference to this variable.
-If you do want to pass flags down normally, but don't want to pass down
-the command line variable definitions, you can reset 'MAKEOVERRIDES' to
-empty, like this:
-
-     MAKEOVERRIDES =
-
-This is not usually useful to do.  However, some systems have a small
-fixed limit on the size of the environment, and putting so much
-information into the value of 'MAKEFLAGS' can exceed it.  If you see the
-error message 'Arg list too long', this may be the problem.  (For strict
-compliance with POSIX.2, changing 'MAKEOVERRIDES' does not affect
-'MAKEFLAGS' if the special target '.POSIX' appears in the makefile.  You
-probably do not care about this.)
-
-   A similar variable 'MFLAGS' exists also, for historical
-compatibility.  It has the same value as 'MAKEFLAGS' except that it does
-not contain the command line variable definitions, and it always begins
-with a hyphen unless it is empty ('MAKEFLAGS' begins with a hyphen only
-when it begins with an option that has no single-letter version, such as
-'--warn-undefined-variables').  'MFLAGS' was traditionally used
-explicitly in the recursive 'make' command, like this:
-
-     subsystem:
-             cd subdir && $(MAKE) $(MFLAGS)
-
-but now 'MAKEFLAGS' makes this usage redundant.  If you want your
-makefiles to be compatible with old 'make' programs, use this technique;
-it will work fine with more modern 'make' versions too.
-
-   The 'MAKEFLAGS' variable can also be useful if you want to have
-certain options, such as '-k' (*note Summary of Options: Options
-Summary.), set each time you run 'make'.  You simply put a value for
-'MAKEFLAGS' in your environment.  You can also set 'MAKEFLAGS' in a
-makefile, to specify additional flags that should also be in effect for
-that makefile.  (Note that you cannot use 'MFLAGS' this way.  That
-variable is set only for compatibility; 'make' does not interpret a
-value you set for it in any way.)
-
-   When 'make' interprets the value of 'MAKEFLAGS' (either from the
-environment or from a makefile), it first prepends a hyphen if the value
-does not already begin with one.  Then it chops the value into words
-separated by blanks, and parses these words as if they were options
-given on the command line (except that '-C', '-f', '-h', '-o', '-W', and
-their long-named versions are ignored; and there is no error for an
-invalid option).
-
-   If you do put 'MAKEFLAGS' in your environment, you should be sure not
-to include any options that will drastically affect the actions of
-'make' and undermine the purpose of makefiles and of 'make' itself.  For
-instance, the '-t', '-n', and '-q' options, if put in one of these
-variables, could have disastrous consequences and would certainly have
-at least surprising and probably annoying effects.
-
-   If you'd like to run other implementations of 'make' in addition to
-GNU 'make', and hence do not want to add GNU 'make'-specific flags to
-the 'MAKEFLAGS' variable, you can add them to the 'GNUMAKEFLAGS'
-variable instead.  This variable is parsed just before 'MAKEFLAGS', in
-the same way as 'MAKEFLAGS'.  When 'make' constructs 'MAKEFLAGS' to pass
-to a recursive 'make' it will include all flags, even those taken from
-'GNUMAKEFLAGS'.  As a result, after parsing 'GNUMAKEFLAGS' GNU 'make'
-sets this variable to the empty string to avoid duplicating flags during
-recursion.
-
-   It's best to use 'GNUMAKEFLAGS' only with flags which won't
-materially change the behavior of your makefiles.  If your makefiles
-require GNU make anyway then simply use 'MAKEFLAGS'.  Flags such as
-'--no-print-directory' or '--output-sync' may be appropriate for
-'GNUMAKEFLAGS'.

-
-5.7.4 The '--print-directory' Option
-------------------------------------
-
-If you use several levels of recursive 'make' invocations, the '-w' or
-'--print-directory' option can make the output a lot easier to
-understand by showing each directory as 'make' starts processing it and
-as 'make' finishes processing it.  For example, if 'make -w' is run in
-the directory '/u/gnu/make', 'make' will print a line of the form:
-
-     make: Entering directory `/u/gnu/make'.
-
-before doing anything else, and a line of the form:
-
-     make: Leaving directory `/u/gnu/make'.
-
-when processing is completed.
-
-   Normally, you do not need to specify this option because 'make' does
-it for you: '-w' is turned on automatically when you use the '-C'
-option, and in sub-'make's.  'make' will not automatically turn on '-w'
-if you also use '-s', which says to be silent, or if you use
-'--no-print-directory' to explicitly disable it.

-
-5.8 Defining Canned Recipes
-===========================
-
-When the same sequence of commands is useful in making various targets,
-you can define it as a canned sequence with the 'define' directive, and
-refer to the canned sequence from the recipes for those targets.  The
-canned sequence is actually a variable, so the name must not conflict
-with other variable names.
-
-   Here is an example of defining a canned recipe:
-
-     define run-yacc =
-     yacc $(firstword $^)
-     mv y.tab.c $@
-     endef
-
-Here 'run-yacc' is the name of the variable being defined; 'endef' marks
-the end of the definition; the lines in between are the commands.  The
-'define' directive does not expand variable references and function
-calls in the canned sequence; the '$' characters, parentheses, variable
-names, and so on, all become part of the value of the variable you are
-defining.  *Note Defining Multi-Line Variables: Multi-Line, for a
-complete explanation of 'define'.
-
-   The first command in this example runs Yacc on the first prerequisite
-of whichever rule uses the canned sequence.  The output file from Yacc
-is always named 'y.tab.c'.  The second command moves the output to the
-rule's target file name.
-
-   To use the canned sequence, substitute the variable into the recipe
-of a rule.  You can substitute it like any other variable (*note Basics
-of Variable References: Reference.).  Because variables defined by
-'define' are recursively expanded variables, all the variable references
-you wrote inside the 'define' are expanded now.  For example:
-
-     foo.c : foo.y
-             $(run-yacc)
-
-'foo.y' will be substituted for the variable '$^' when it occurs in
-'run-yacc''s value, and 'foo.c' for '$@'.
-
-   This is a realistic example, but this particular one is not needed in
-practice because 'make' has an implicit rule to figure out these
-commands based on the file names involved (*note Using Implicit Rules:
-Implicit Rules.).
-
-   In recipe execution, each line of a canned sequence is treated just
-as if the line appeared on its own in the rule, preceded by a tab.  In
-particular, 'make' invokes a separate sub-shell for each line.  You can
-use the special prefix characters that affect command lines ('@', '-',
-and '+') on each line of a canned sequence.  *Note Writing Recipes in
-Rules: Recipes.  For example, using this canned sequence:
-
-     define frobnicate =
-     @echo "frobnicating target $@"
-     frob-step-1 $< -o $@-step-1
-     frob-step-2 $@-step-1 -o $@
-     endef
-
-'make' will not echo the first line, the 'echo' command.  But it _will_
-echo the following two recipe lines.
-
-   On the other hand, prefix characters on the recipe line that refers
-to a canned sequence apply to every line in the sequence.  So the rule:
-
-     frob.out: frob.in
-             @$(frobnicate)
-
-does not echo _any_ recipe lines.  (*Note Recipe Echoing: Echoing, for a
-full explanation of '@'.)
-
-
-File: make.info,  Node: Empty Recipes,  Prev: Canned Recipes,  Up: Recipes
-
-5.9 Using Empty Recipes
-=======================
-
-It is sometimes useful to define recipes which do nothing.  This is done
-simply by giving a recipe that consists of nothing but whitespace.  For
-example:
-
-     target: ;
-
-defines an empty recipe for 'target'.  You could also use a line
-beginning with a recipe prefix character to define an empty recipe, but
-this would be confusing because such a line looks empty.
-
-   You may be wondering why you would want to define a recipe that does
-nothing.  One reason this is useful is to prevent a target from getting
-implicit recipes (from implicit rules or the '.DEFAULT' special target;
-*note Implicit Rules:: and *note Defining Last-Resort Default Rules:
-Last Resort.).
-
-   Empty recipes can also be used to avoid errors for targets that will
-be created as a side-effect of another recipe: if the target does not
-exist the empty recipe ensures that 'make' won't complain that it
-doesn't know how to build the target, and 'make' will assume the target
-is out of date.
-
-   You may be inclined to define empty recipes for targets that are not
-actual files, but only exist so that their prerequisites can be remade.
-However, this is not the best way to do that, because the prerequisites
-may not be remade properly if the target file actually does exist.
-*Note Phony Targets: Phony Targets, for a better way to do this.

-6 How to Use Variables
-**********************
-
-A "variable" is a name defined in a makefile to represent a string of
-text, called the variable's "value".  These values are substituted by
-explicit request into targets, prerequisites, recipes, and other parts
-of the makefile.  (In some other versions of 'make', variables are
-called "macros".)
-
-   Variables and functions in all parts of a makefile are expanded when
-read, except for in recipes, the right-hand sides of variable
-definitions using '=', and the bodies of variable definitions using the
-'define' directive.
-
-   Variables can represent lists of file names, options to pass to
-compilers, programs to run, directories to look in for source files,
-directories to write output in, or anything else you can imagine.
-
-   A variable name may be any sequence of characters not containing ':',
-'#', '=', or whitespace.  However, variable names containing characters
-other than letters, numbers, and underscores should be considered
-carefully, as in some shells they cannot be passed through the
-environment to a sub-'make' (*note Communicating Variables to a
-Sub-'make': Variables/Recursion.).  Variable names beginning with '.'
-and an uppercase letter may be given special meaning in future versions
-of 'make'.
-
-   Variable names are case-sensitive.  The names 'foo', 'FOO', and 'Foo'
-all refer to different variables.
-
-   It is traditional to use upper case letters in variable names, but we
-recommend using lower case letters for variable names that serve
-internal purposes in the makefile, and reserving upper case for
-parameters that control implicit rules or for parameters that the user
-should override with command options (*note Overriding Variables:

-
-   A few variables have names that are a single punctuation character or
-just a few characters.  These are the "automatic variables", and they

-6.1 Basics of Variable References
-=================================
-
-To substitute a variable's value, write a dollar sign followed by the
-name of the variable in parentheses or braces: either '$(foo)' or
-'${foo}' is a valid reference to the variable 'foo'.  This special
-significance of '$' is why you must write '$$' to have the effect of a
-single dollar sign in a file name or recipe.
-
-   Variable references can be used in any context: targets,
-prerequisites, recipes, most directives, and new variable values.  Here
-is an example of a common case, where a variable holds the names of all
-the object files in a program:
-
-     objects = program.o foo.o utils.o
-     program : $(objects)
-             cc -o program $(objects)
-
-     $(objects) : defs.h
-
-   Variable references work by strict textual substitution.  Thus, the
-rule
-
-     foo = c
-     prog.o : prog.$(foo)
-             $(foo)$(foo) -$(foo) prog.$(foo)
-
-could be used to compile a C program 'prog.c'.  Since spaces before the
-variable value are ignored in variable assignments, the value of 'foo'
-is precisely 'c'.  (Don't actually write your makefiles this way!)
-
-   A dollar sign followed by a character other than a dollar sign,
-open-parenthesis or open-brace treats that single character as the
-variable name.  Thus, you could reference the variable 'x' with '$x'.
-However, this practice can lead to confusion (e.g., '$foo' refers to the
-variable 'f' followed by the string 'oo') so we recommend using
-parentheses or braces around all variables, even single-letter
-variables, unless omitting them gives significant readability
-improvements.  One place where readability is often improved is
-automatic variables (*note Automatic Variables::).

-
-6.2 The Two Flavors of Variables
-================================
-
-There are two ways that a variable in GNU 'make' can have a value; we
-call them the two "flavors" of variables.  The two flavors are
-distinguished in how they are defined and in what they do when expanded.
-
-   The first flavor of variable is a "recursively expanded" variable.
-Variables of this sort are defined by lines using '=' (*note Setting
-Variables: Setting.) or by the 'define' directive (*note Defining
-Multi-Line Variables: Multi-Line.).  The value you specify is installed
-verbatim; if it contains references to other variables, these references
-are expanded whenever this variable is substituted (in the course of
-expanding some other string).  When this happens, it is called
-"recursive expansion".
-
-   For example,
-
-     foo = $(bar)
-     bar = $(ugh)
-     ugh = Huh?
-
-     all:;echo $(foo)
-
-will echo 'Huh?': '$(foo)' expands to '$(bar)' which expands to '$(ugh)'
-which finally expands to 'Huh?'.
-
-   This flavor of variable is the only sort supported by most other
-versions of 'make'.  It has its advantages and its disadvantages.  An
-advantage (most would say) is that:
-
-     CFLAGS = $(include_dirs) -O
-     include_dirs = -Ifoo -Ibar
-
-will do what was intended: when 'CFLAGS' is expanded in a recipe, it
-will expand to '-Ifoo -Ibar -O'.  A major disadvantage is that you
-cannot append something on the end of a variable, as in
-
-     CFLAGS = $(CFLAGS) -O
-
-because it will cause an infinite loop in the variable expansion.
-(Actually 'make' detects the infinite loop and reports an error.)
-
-   Another disadvantage is that any functions (*note Functions for
-Transforming Text: Functions.) referenced in the definition will be
-executed every time the variable is expanded.  This makes 'make' run
-slower; worse, it causes the 'wildcard' and 'shell' functions to give
-unpredictable results because you cannot easily control when they are
-called, or even how many times.
-
-   To avoid all the problems and inconveniences of recursively expanded
-variables, there is another flavor: simply expanded variables.
-
-   "Simply expanded variables" are defined by lines using ':=' or '::='
-(*note Setting Variables: Setting.).  Both forms are equivalent in GNU
-'make'; however only the '::=' form is described by the POSIX standard
-(support for '::=' was added to the POSIX standard in 2012, so older
-versions of 'make' won't accept this form either).
-
-   The value of a simply expanded variable is scanned once and for all,
-expanding any references to other variables and functions, when the
-variable is defined.  The actual value of the simply expanded variable
-is the result of expanding the text that you write.  It does not contain
-any references to other variables; it contains their values _as of the
-time this variable was defined_.  Therefore,
-
-     x := foo
-     y := $(x) bar
-     x := later
-
-is equivalent to
-
-     y := foo bar
-     x := later
-
-   When a simply expanded variable is referenced, its value is
-substituted verbatim.
-
-   Here is a somewhat more complicated example, illustrating the use of
-':=' in conjunction with the 'shell' function.  (*Note The 'shell'
-Function: Shell Function.)  This example also shows use of the variable
-'MAKELEVEL', which is changed when it is passed down from level to
-level.  (*Note Communicating Variables to a Sub-'make':
-Variables/Recursion, for information about 'MAKELEVEL'.)
-
-     ifeq (0,${MAKELEVEL})
-     whoami    := $(shell whoami)
-     host-type := $(shell arch)
-     MAKE := ${MAKE} host-type=${host-type} whoami=${whoami}
-     endif
-
-An advantage of this use of ':=' is that a typical 'descend into a
-directory' recipe then looks like this:
-
-     ${subdirs}:
-             ${MAKE} -C $@ all
-
-   Simply expanded variables generally make complicated makefile
-programming more predictable because they work like variables in most
-programming languages.  They allow you to redefine a variable using its
-own value (or its value processed in some way by one of the expansion
-functions) and to use the expansion functions much more efficiently
-(*note Functions for Transforming Text: Functions.).
-
-   You can also use them to introduce controlled leading whitespace into
-variable values.  Leading whitespace characters are discarded from your
-input before substitution of variable references and function calls;
-this means you can include leading spaces in a variable value by
-protecting them with variable references, like this:
-
-     nullstring :=
-     space := $(nullstring) # end of the line
-
-Here the value of the variable 'space' is precisely one space.  The
-comment '# end of the line' is included here just for clarity.  Since
-trailing space characters are _not_ stripped from variable values, just
-a space at the end of the line would have the same effect (but be rather
-hard to read).  If you put whitespace at the end of a variable value, it
-is a good idea to put a comment like that at the end of the line to make
-your intent clear.  Conversely, if you do _not_ want any whitespace
-characters at the end of your variable value, you must remember not to
-put a random comment on the end of the line after some whitespace, such
-as this:
-
-     dir := /foo/bar    # directory to put the frobs in
-
-Here the value of the variable 'dir' is '/foo/bar    ' (with four
-trailing spaces), which was probably not the intention.  (Imagine
-something like '$(dir)/file' with this definition!)
-
-   There is another assignment operator for variables, '?='.  This is
-called a conditional variable assignment operator, because it only has
-an effect if the variable is not yet defined.  This statement:
-
-     FOO ?= bar
-
-is exactly equivalent to this (*note The 'origin' Function: Origin
-Function.):
-
-     ifeq ($(origin FOO), undefined)
-       FOO = bar
-     endif
-
-   Note that a variable set to an empty value is still defined, so '?='
-will not set that variable.

-6.3 Advanced Features for Reference to Variables
-================================================
-
-This section describes some advanced features you can use to reference
-variables in more flexible ways.
-
-* Menu:
-
-* Substitution Refs::           Referencing a variable with
-                                  substitutions on the value.
-* Computed Names::              Computing the name of the variable to refer to.
-
-
-File: make.info,  Node: Substitution Refs,  Next: Computed Names,  Prev: Advanced,  Up: Advanced
-
-6.3.1 Substitution References
------------------------------
-
-A "substitution reference" substitutes the value of a variable with
-alterations that you specify.  It has the form '$(VAR:A=B)' (or
-'${VAR:A=B}') and its meaning is to take the value of the variable VAR,
-replace every A at the end of a word with B in that value, and
-substitute the resulting string.
-
-   When we say "at the end of a word", we mean that A must appear either
-followed by whitespace or at the end of the value in order to be
-replaced; other occurrences of A in the value are unaltered.  For
-example:
-
-     foo := a.o b.o l.a c.o
-     bar := $(foo:.o=.c)
-
-sets 'bar' to 'a.c b.c l.a c.c'.  *Note Setting Variables: Setting.
-
-   A substitution reference is shorthand for the 'patsubst' expansion
-function (*note Functions for String Substitution and Analysis: Text
-Functions.): '$(VAR:A=B)' is equivalent to '$(patsubst %A,%B,VAR)'.  We
-provide substitution references as well as 'patsubst' for compatibility
-with other implementations of 'make'.
-
-   Another type of substitution reference lets you use the full power of
-the 'patsubst' function.  It has the same form '$(VAR:A=B)' described
-above, except that now A must contain a single '%' character.  This case
-is equivalent to '$(patsubst A,B,$(VAR))'.  *Note Functions for String
-Substitution and Analysis: Text Functions, for a description of the
-'patsubst' function.
-
-For example:
-
-     foo := a.o b.o l.a c.o
-     bar := $(foo:%.o=%.c)
-
-sets 'bar' to 'a.c b.c l.a c.c'.
-
-
-File: make.info,  Node: Computed Names,  Prev: Substitution Refs,  Up: Advanced
-
-6.3.2 Computed Variable Names
------------------------------
-
-Computed variable names are a complicated concept needed only for
-sophisticated makefile programming.  For most purposes you need not
-consider them, except to know that making a variable with a dollar sign
-in its name might have strange results.  However, if you are the type
-that wants to understand everything, or you are actually interested in
-what they do, read on.
-
-   Variables may be referenced inside the name of a variable.  This is
-called a "computed variable name" or a "nested variable reference".  For
-example,
-
-     x = y
-     y = z
-     a := $($(x))
-
-defines 'a' as 'z': the '$(x)' inside '$($(x))' expands to 'y', so
-'$($(x))' expands to '$(y)' which in turn expands to 'z'.  Here the name
-of the variable to reference is not stated explicitly; it is computed by
-expansion of '$(x)'.  The reference '$(x)' here is nested within the
-outer variable reference.
-
-   The previous example shows two levels of nesting, but any number of
-levels is possible.  For example, here are three levels:
-
-     x = y
-     y = z
-     z = u
-     a := $($($(x)))
-
-Here the innermost '$(x)' expands to 'y', so '$($(x))' expands to '$(y)'
-which in turn expands to 'z'; now we have '$(z)', which becomes 'u'.
-
-   References to recursively-expanded variables within a variable name
-are re-expanded in the usual fashion.  For example:
-
-     x = $(y)
-     y = z
-     z = Hello
-     a := $($(x))
-
-defines 'a' as 'Hello': '$($(x))' becomes '$($(y))' which becomes '$(z)'
-which becomes 'Hello'.
-
-   Nested variable references can also contain modified references and
-function invocations (*note Functions for Transforming Text:
-Functions.), just like any other reference.  For example, using the
-'subst' function (*note Functions for String Substitution and Analysis:
-Text Functions.):
-
-     x = variable1
-     variable2 := Hello
-     y = $(subst 1,2,$(x))
-     z = y
-     a := $($($(z)))
-
-eventually defines 'a' as 'Hello'.  It is doubtful that anyone would
-ever want to write a nested reference as convoluted as this one, but it
-works: '$($($(z)))' expands to '$($(y))' which becomes '$($(subst
-1,2,$(x)))'.  This gets the value 'variable1' from 'x' and changes it by
-substitution to 'variable2', so that the entire string becomes
-'$(variable2)', a simple variable reference whose value is 'Hello'.
-
-   A computed variable name need not consist entirely of a single
-variable reference.  It can contain several variable references, as well
-as some invariant text.  For example,
-
-     a_dirs := dira dirb
-     1_dirs := dir1 dir2
-
-     a_files := filea fileb
-     1_files := file1 file2
-
-     ifeq "$(use_a)" "yes"
-     a1 := a
-     else
-     a1 := 1
-     endif
-
-     ifeq "$(use_dirs)" "yes"
-     df := dirs
-     else
-     df := files
-     endif
-
-     dirs := $($(a1)_$(df))
-
-will give 'dirs' the same value as 'a_dirs', '1_dirs', 'a_files' or
-'1_files' depending on the settings of 'use_a' and 'use_dirs'.
-
-   Computed variable names can also be used in substitution references:
-
-     a_objects := a.o b.o c.o
-     1_objects := 1.o 2.o 3.o
-
-     sources := $($(a1)_objects:.o=.c)
-
-defines 'sources' as either 'a.c b.c c.c' or '1.c 2.c 3.c', depending on
-the value of 'a1'.
-
-   The only restriction on this sort of use of nested variable
-references is that they cannot specify part of the name of a function to
-be called.  This is because the test for a recognized function name is
-done before the expansion of nested references.  For example,
-
-     ifdef do_sort
-     func := sort
-     else
-     func := strip
-     endif
-
-     bar := a d b g q c
-
-     foo := $($(func) $(bar))
-
-attempts to give 'foo' the value of the variable 'sort a d b g q c' or
-'strip a d b g q c', rather than giving 'a d b g q c' as the argument to
-either the 'sort' or the 'strip' function.  This restriction could be
-removed in the future if that change is shown to be a good idea.
-
-   You can also use computed variable names in the left-hand side of a
-variable assignment, or in a 'define' directive, as in:
-
-     dir = foo
-     $(dir)_sources := $(wildcard $(dir)/*.c)
-     define $(dir)_print =
-     lpr $($(dir)_sources)
-     endef
-
-This example defines the variables 'dir', 'foo_sources', and
-'foo_print'.
-
-   Note that "nested variable references" are quite different from
-"recursively expanded variables" (*note The Two Flavors of Variables:
-Flavors.), though both are used together in complex ways when doing
-makefile programming.

-6.4 How Variables Get Their Values
-==================================
-
-Variables can get values in several different ways:
-
-   * You can specify an overriding value when you run 'make'.  *Note
-     Overriding Variables: Overriding.
-
-   * You can specify a value in the makefile, either with an assignment
-     (*note Setting Variables: Setting.) or with a verbatim definition
-     (*note Defining Multi-Line Variables: Multi-Line.).
-
-   * Variables in the environment become 'make' variables.  *Note
-     Variables from the Environment: Environment.
-
-   * Several "automatic" variables are given new values for each rule.
-     Each of these has a single conventional use.  *Note Automatic
-     Variables::.
-
-   * Several variables have constant initial values.  *Note Variables
-     Used by Implicit Rules: Implicit Variables.
-
-
-File: make.info,  Node: Setting,  Next: Appending,  Prev: Values,  Up: Using Variables
-
-6.5 Setting Variables
-=====================
-
-To set a variable from the makefile, write a line starting with the
-variable name followed by '=', ':=', or '::='.  Whatever follows the
-'=', ':=', or '::=' on the line becomes the value.  For example,
-
-     objects = main.o foo.o bar.o utils.o
-
-defines a variable named 'objects'.  Whitespace around the variable name
-and immediately after the '=' is ignored.
-
-   Variables defined with '=' are "recursively expanded" variables.
-Variables defined with ':=' or '::=' are "simply expanded" variables;
-these definitions can contain variable references which will be expanded
-before the definition is made.  *Note The Two Flavors of Variables:
-Flavors.
-
-   The variable name may contain function and variable references, which
-are expanded when the line is read to find the actual variable name to
-use.
-
-   There is no limit on the length of the value of a variable except the
-amount of memory on the computer.  You can split the value of a variable
-into multiple physical lines for readability (*note Splitting Long
-Lines: Splitting Lines.).
-
-   Most variable names are considered to have the empty string as a
-value if you have never set them.  Several variables have built-in
-initial values that are not empty, but you can set them in the usual
-ways (*note Variables Used by Implicit Rules: Implicit Variables.).
-Several special variables are set automatically to a new value for each
-rule; these are called the "automatic" variables (*note Automatic
-Variables::).
-
-   If you'd like a variable to be set to a value only if it's not
-already set, then you can use the shorthand operator '?=' instead of
-'='.  These two settings of the variable 'FOO' are identical (*note The
-'origin' Function: Origin Function.):
-
-     FOO ?= bar
-
-and
-
-     ifeq ($(origin FOO), undefined)
-     FOO = bar
-     endif
-
-   The shell assignment operator '!=' can be used to execute a shell
-script and set a variable to its output.  This operator first evaluates
-the right-hand side, then passes that result to the shell for execution.
-If the result of the execution ends in a newline, that one newline is
-removed; all other newlines are replaced by spaces.  The resulting
-string is then placed into the named recursively-expanded variable.  For
-example:
-
-     hash != printf '\043'
-     file_list != find . -name '*.c'
-
-   If the result of the execution could produce a '$', and you don't
-intend what follows that to be interpreted as a make variable or
-function reference, then you must replace every '$' with '$$' as part of
-the execution.  Alternatively, you can set a simply expanded variable to
-the result of running a program using the 'shell' function call.  *Note
-The 'shell' Function: Shell Function.  For example:
-
-     hash := $(shell printf '\043')
-     var := $(shell find . -name "*.c")
-
-   As with the 'shell' function, the exit status of the just-invoked
-shell script is stored in the '.SHELLSTATUS' variable.
-
-
-File: make.info,  Node: Appending,  Next: Override Directive,  Prev: Setting,  Up: Using Variables
-
-6.6 Appending More Text to Variables
-====================================
-
-Often it is useful to add more text to the value of a variable already
-defined.  You do this with a line containing '+=', like this:
-
-     objects += another.o
-
-This takes the value of the variable 'objects', and adds the text
-'another.o' to it (preceded by a single space, if it has a value
-already).  Thus:
-
-     objects = main.o foo.o bar.o utils.o
-     objects += another.o
-
-sets 'objects' to 'main.o foo.o bar.o utils.o another.o'.
-
-   Using '+=' is similar to:
-
-     objects = main.o foo.o bar.o utils.o
-     objects := $(objects) another.o
-
-but differs in ways that become important when you use more complex
-values.
-
-   When the variable in question has not been defined before, '+=' acts
-just like normal '=': it defines a recursively-expanded variable.
-However, when there _is_ a previous definition, exactly what '+=' does
-depends on what flavor of variable you defined originally.  *Note The
-Two Flavors of Variables: Flavors, for an explanation of the two flavors
-of variables.
-
-   When you add to a variable's value with '+=', 'make' acts essentially
-as if you had included the extra text in the initial definition of the
-variable.  If you defined it first with ':=' or '::=', making it a
-simply-expanded variable, '+=' adds to that simply-expanded definition,
-and expands the new text before appending it to the old value just as
-':=' does (see *note Setting Variables: Setting, for a full explanation
-of ':=' or '::=').  In fact,
-
-     variable := value
-     variable += more
-
-is exactly equivalent to:
-
-     variable := value
-     variable := $(variable) more
-
-   On the other hand, when you use '+=' with a variable that you defined
-first to be recursively-expanded using plain '=', 'make' does something
-a bit different.  Recall that when you define a recursively-expanded
-variable, 'make' does not expand the value you set for variable and
-function references immediately.  Instead it stores the text verbatim,
-and saves these variable and function references to be expanded later,
-when you refer to the new variable (*note The Two Flavors of Variables:
-Flavors.).  When you use '+=' on a recursively-expanded variable, it is
-this unexpanded text to which 'make' appends the new text you specify.
-
-     variable = value
-     variable += more
-
-is roughly equivalent to:
-
-     temp = value
-     variable = $(temp) more
-
-except that of course it never defines a variable called 'temp'.  The
-importance of this comes when the variable's old value contains variable
-references.  Take this common example:
-
-     CFLAGS = $(includes) -O
-     ...
-     CFLAGS += -pg # enable profiling
-
-The first line defines the 'CFLAGS' variable with a reference to another
-variable, 'includes'.  ('CFLAGS' is used by the rules for C compilation;
-*note Catalogue of Built-In Rules: Catalogue of Rules.)  Using '=' for
-the definition makes 'CFLAGS' a recursively-expanded variable, meaning
-'$(includes) -O' is _not_ expanded when 'make' processes the definition
-of 'CFLAGS'.  Thus, 'includes' need not be defined yet for its value to
-take effect.  It only has to be defined before any reference to
-'CFLAGS'.  If we tried to append to the value of 'CFLAGS' without using
-'+=', we might do it like this:
-
-     CFLAGS := $(CFLAGS) -pg # enable profiling
-
-This is pretty close, but not quite what we want.  Using ':=' redefines
-'CFLAGS' as a simply-expanded variable; this means 'make' expands the
-text '$(CFLAGS) -pg' before setting the variable.  If 'includes' is not
-yet defined, we get ' -O -pg', and a later definition of 'includes' will
-have no effect.  Conversely, by using '+=' we set 'CFLAGS' to the
-_unexpanded_ value '$(includes) -O -pg'.  Thus we preserve the reference
-to 'includes', so if that variable gets defined at any later point, a
-reference like '$(CFLAGS)' still uses its value.

-6.7 The 'override' Directive
-============================
-
-If a variable has been set with a command argument (*note Overriding
-Variables: Overriding.), then ordinary assignments in the makefile are
-ignored.  If you want to set the variable in the makefile even though it
-was set with a command argument, you can use an 'override' directive,
-which is a line that looks like this:
-
-     override VARIABLE = VALUE
-
-or
-
-     override VARIABLE := VALUE
-
-   To append more text to a variable defined on the command line, use:
-
-     override VARIABLE += MORE TEXT
-
-*Note Appending More Text to Variables: Appending.
-
-   Variable assignments marked with the 'override' flag have a higher
-priority than all other assignments, except another 'override'.
-Subsequent assignments or appends to this variable which are not marked
-'override' will be ignored.
-
-   The 'override' directive was not invented for escalation in the war
-between makefiles and command arguments.  It was invented so you can
-alter and add to values that the user specifies with command arguments.
-
-   For example, suppose you always want the '-g' switch when you run the
-C compiler, but you would like to allow the user to specify the other
-switches with a command argument just as usual.  You could use this
-'override' directive:
-
-     override CFLAGS += -g
-
-   You can also use 'override' directives with 'define' directives.
-This is done as you might expect:
-
-     override define foo =
-     bar
-     endef
-

-
-6.8 Defining Multi-Line Variables
-=================================
-
-Another way to set the value of a variable is to use the 'define'
-directive.  This directive has an unusual syntax which allows newline
-characters to be included in the value, which is convenient for defining
-both canned sequences of commands (*note Defining Canned Recipes: Canned
-Recipes.), and also sections of makefile syntax to use with 'eval'
-(*note Eval Function::).
-
-   The 'define' directive is followed on the same line by the name of
-the variable being defined and an (optional) assignment operator, and
-nothing more.  The value to give the variable appears on the following
-lines.  The end of the value is marked by a line containing just the
-word 'endef'.
-
-   Aside from this difference in syntax, 'define' works just like any
-other variable definition.  The variable name may contain function and
-variable references, which are expanded when the directive is read to
-find the actual variable name to use.
-
-   The final newline before the 'endef' is not included in the value; if
-you want your value to contain a trailing newline you must include a
-blank line.  For example in order to define a variable that contains a
-newline character you must use _two_ empty lines, not one:
-
-     define newline
-
-
-     endef
-
-   You may omit the variable assignment operator if you prefer.  If
-omitted, 'make' assumes it to be '=' and creates a recursively-expanded
-variable (*note The Two Flavors of Variables: Flavors.).  When using a
-'+=' operator, the value is appended to the previous value as with any
-other append operation: with a single space separating the old and new
-values.
-
-   You may nest 'define' directives: 'make' will keep track of nested
-directives and report an error if they are not all properly closed with
-'endef'.  Note that lines beginning with the recipe prefix character are
-considered part of a recipe, so any 'define' or 'endef' strings
-appearing on such a line will not be considered 'make' directives.
-
-     define two-lines
-     echo foo
-     echo $(bar)
-     endef
-
-   When used in a recipe, the previous example is functionally
-equivalent to this:
-
-     two-lines = echo foo; echo $(bar)
-
-since two commands separated by semicolon behave much like two separate
-shell commands.  However, note that using two separate lines means
-'make' will invoke the shell twice, running an independent sub-shell for
-each line.  *Note Recipe Execution: Execution.
-
-   If you want variable definitions made with 'define' to take
-precedence over command-line variable definitions, you can use the
-'override' directive together with 'define':
-
-     override define two-lines =
-     foo
-     $(bar)
-     endef
-
-*Note The 'override' Directive: Override Directive.

-
-6.9 Undefining Variables
-========================
-
-If you want to clear a variable, setting its value to empty is usually
-sufficient.  Expanding such a variable will yield the same result (empty
-string) regardless of whether it was set or not.  However, if you are
-using the 'flavor' (*note Flavor Function::) and 'origin' (*note Origin
-Function::) functions, there is a difference between a variable that was
-never set and a variable with an empty value.  In such situations you
-may want to use the 'undefine' directive to make a variable appear as if
-it was never set.  For example:
-
-     foo := foo
-     bar = bar
-
-     undefine foo
-     undefine bar
-
-     $(info $(origin foo))
-     $(info $(flavor bar))
-
-   This example will print "undefined" for both variables.
-
-   If you want to undefine a command-line variable definition, you can
-use the 'override' directive together with 'undefine', similar to how
-this is done for variable definitions:
-
-     override undefine CFLAGS
-
-
-File: make.info,  Node: Environment,  Next: Target-specific,  Prev: Undefine Directive,  Up: Using Variables
-
-6.10 Variables from the Environment
-===================================
-
-Variables in 'make' can come from the environment in which 'make' is
-run.  Every environment variable that 'make' sees when it starts up is
-transformed into a 'make' variable with the same name and value.
-However, an explicit assignment in the makefile, or with a command
-argument, overrides the environment.  (If the '-e' flag is specified,
-then values from the environment override assignments in the makefile.
-*Note Summary of Options: Options Summary.  But this is not recommended
-practice.)
-
-   Thus, by setting the variable 'CFLAGS' in your environment, you can
-cause all C compilations in most makefiles to use the compiler switches
-you prefer.  This is safe for variables with standard or conventional
-meanings because you know that no makefile will use them for other
-things.  (Note this is not totally reliable; some makefiles set 'CFLAGS'
-explicitly and therefore are not affected by the value in the
-environment.)
-
-   When 'make' runs a recipe, variables defined in the makefile are
-placed into the environment of each shell.  This allows you to pass
-values to sub-'make' invocations (*note Recursive Use of 'make':
-Recursion.).  By default, only variables that came from the environment
-or the command line are passed to recursive invocations.  You can use
-the 'export' directive to pass other variables.  *Note Communicating
-Variables to a Sub-'make': Variables/Recursion, for full details.
-
-   Other use of variables from the environment is not recommended.  It
-is not wise for makefiles to depend for their functioning on environment
-variables set up outside their control, since this would cause different
-users to get different results from the same makefile.  This is against
-the whole purpose of most makefiles.
-
-   Such problems would be especially likely with the variable 'SHELL',
-which is normally present in the environment to specify the user's
-choice of interactive shell.  It would be very undesirable for this
-choice to affect 'make'; so, 'make' handles the 'SHELL' environment
-variable in a special way; see *note Choosing the Shell::.
-

-File: make.info,  Node: Target-specific,  Next: Pattern-specific,  Prev: Environment,  Up: Using Variables
-
-6.11 Target-specific Variable Values
-====================================
-
-Variable values in 'make' are usually global; that is, they are the same
-regardless of where they are evaluated (unless they're reset, of
-course).  One exception to that is automatic variables (*note Automatic
-Variables::).
-
-   The other exception is "target-specific variable values".  This
-feature allows you to define different values for the same variable,
-based on the target that 'make' is currently building.  As with
-automatic variables, these values are only available within the context
-of a target's recipe (and in other target-specific assignments).
-
-   Set a target-specific variable value like this:
-
-     TARGET ... : VARIABLE-ASSIGNMENT
-
-   Target-specific variable assignments can be prefixed with any or all
-of the special keywords 'export', 'override', or 'private'; these apply
-their normal behavior to this instance of the variable only.
-
-   Multiple TARGET values create a target-specific variable value for
-each member of the target list individually.
-
-   The VARIABLE-ASSIGNMENT can be any valid form of assignment;
-recursive ('='), simple (':=' or '::='), appending ('+='), or
-conditional ('?=').  All variables that appear within the
-VARIABLE-ASSIGNMENT are evaluated within the context of the target:
-thus, any previously-defined target-specific variable values will be in
-effect.  Note that this variable is actually distinct from any "global"
-value: the two variables do not have to have the same flavor (recursive
-vs. simple).
-
-   Target-specific variables have the same priority as any other
-makefile variable.  Variables provided on the command line (and in the
-environment if the '-e' option is in force) will take precedence.
-Specifying the 'override' directive will allow the target-specific
-variable value to be preferred.
-
-   There is one more special feature of target-specific variables: when
-you define a target-specific variable that variable value is also in
-effect for all prerequisites of this target, and all their
-prerequisites, etc. (unless those prerequisites override that variable
-with their own target-specific variable value).  So, for example, a
-statement like this:
-
-     prog : CFLAGS = -g
-     prog : prog.o foo.o bar.o
-
-will set 'CFLAGS' to '-g' in the recipe for 'prog', but it will also set
-'CFLAGS' to '-g' in the recipes that create 'prog.o', 'foo.o', and
-'bar.o', and any recipes which create their prerequisites.
-
-   Be aware that a given prerequisite will only be built once per
-invocation of make, at most.  If the same file is a prerequisite of
-multiple targets, and each of those targets has a different value for
-the same target-specific variable, then the first target to be built
-will cause that prerequisite to be built and the prerequisite will
-inherit the target-specific value from the first target.  It will ignore
-the target-specific values from any other targets.

-
-6.12 Pattern-specific Variable Values
-=====================================
-
-In addition to target-specific variable values (*note Target-specific
-Variable Values: Target-specific.), GNU 'make' supports pattern-specific
-variable values.  In this form, the variable is defined for any target
-that matches the pattern specified.
-
-   Set a pattern-specific variable value like this:
-
-     PATTERN ... : VARIABLE-ASSIGNMENT
-   where PATTERN is a %-pattern.  As with target-specific variable
-values, multiple PATTERN values create a pattern-specific variable value
-for each pattern individually.  The VARIABLE-ASSIGNMENT can be any valid
-form of assignment.  Any command line variable setting will take
-precedence, unless 'override' is specified.
-
-   For example:
-
-     %.o : CFLAGS = -O
-
-will assign 'CFLAGS' the value of '-O' for all targets matching the
-pattern '%.o'.
-
-   If a target matches more than one pattern, the matching
-pattern-specific variables with longer stems are interpreted first.
-This results in more specific variables taking precedence over the more
-generic ones, for example:
-
-     %.o: %.c
-             $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@
-
-     lib/%.o: CFLAGS := -fPIC -g
-     %.o: CFLAGS := -g
-
-     all: foo.o lib/bar.o
-
-   In this example the first definition of the 'CFLAGS' variable will be
-used to update 'lib/bar.o' even though the second one also applies to
-this target.  Pattern-specific variables which result in the same stem
-length are considered in the order in which they were defined in the
-makefile.
-
-   Pattern-specific variables are searched after any target-specific
-variables defined explicitly for that target, and before target-specific
-variables defined for the parent target.

-
-6.13 Suppressing Inheritance
-============================
-
-As described in previous sections, 'make' variables are inherited by
-prerequisites.  This capability allows you to modify the behavior of a
-prerequisite based on which targets caused it to be rebuilt.  For
-example, you might set a target-specific variable on a 'debug' target,
-then running 'make debug' will cause that variable to be inherited by
-all prerequisites of 'debug', while just running 'make all' (for
-example) would not have that assignment.
-
-   Sometimes, however, you may not want a variable to be inherited.  For
-these situations, 'make' provides the 'private' modifier.  Although this
-modifier can be used with any variable assignment, it makes the most
-sense with target- and pattern-specific variables.  Any variable marked
-'private' will be visible to its local target but will not be inherited
-by prerequisites of that target.  A global variable marked 'private'
-will be visible in the global scope but will not be inherited by any
-target, and hence will not be visible in any recipe.
-
-   As an example, consider this makefile:
-     EXTRA_CFLAGS =
-
-     prog: private EXTRA_CFLAGS = -L/usr/local/lib
-     prog: a.o b.o
-
-   Due to the 'private' modifier, 'a.o' and 'b.o' will not inherit the
-'EXTRA_CFLAGS' variable assignment from the 'prog' target.
-
-
-File: make.info,  Node: Special Variables,  Prev: Suppressing Inheritance,  Up: Using Variables
-
-6.14 Other Special Variables
-============================
-
-GNU 'make' supports some variables that have special properties.
-
-'MAKEFILE_LIST'
-     Contains the name of each makefile that is parsed by 'make', in the
-     order in which it was parsed.  The name is appended just before
-     'make' begins to parse the makefile.  Thus, if the first thing a
-     makefile does is examine the last word in this variable, it will be
-     the name of the current makefile.  Once the current makefile has
-     used 'include', however, the last word will be the just-included
-     makefile.
-
-     If a makefile named 'Makefile' has this content:
-
-          name1 := $(lastword $(MAKEFILE_LIST))
-
-          include inc.mk
-
-          name2 := $(lastword $(MAKEFILE_LIST))
-
-          all:
-                  @echo name1 = $(name1)
-                  @echo name2 = $(name2)
-
-     then you would expect to see this output:
-
-          name1 = Makefile
-          name2 = inc.mk
-
-'.DEFAULT_GOAL'
-     Sets the default goal to be used if no targets were specified on
-     the command line (*note Arguments to Specify the Goals: Goals.).
-     The '.DEFAULT_GOAL' variable allows you to discover the current
-     default goal, restart the default goal selection algorithm by
-     clearing its value, or to explicitly set the default goal.  The
-     following example illustrates these cases:
-
-          # Query the default goal.
-          ifeq ($(.DEFAULT_GOAL),)
-            $(warning no default goal is set)
-          endif
-
-          .PHONY: foo
-          foo: ; @echo $@
-
-          $(warning default goal is $(.DEFAULT_GOAL))
-
-          # Reset the default goal.
-          .DEFAULT_GOAL :=
-
-          .PHONY: bar
-          bar: ; @echo $@
-
-          $(warning default goal is $(.DEFAULT_GOAL))
-
-          # Set our own.
-          .DEFAULT_GOAL := foo
-
-     This makefile prints:
-
-          no default goal is set
-          default goal is foo
-          default goal is bar
-          foo
-
-     Note that assigning more than one target name to '.DEFAULT_GOAL' is
-     invalid and will result in an error.
-
-'MAKE_RESTARTS'
-     This variable is set only if this instance of 'make' has restarted
-     (*note How Makefiles Are Remade: Remaking Makefiles.): it will
-     contain the number of times this instance has restarted.  Note this
-     is not the same as recursion (counted by the 'MAKELEVEL' variable).
-     You should not set, modify, or export this variable.
-
-'MAKE_TERMOUT'
-'MAKE_TERMERR'
-     When 'make' starts it will check whether stdout and stderr will
-     show their output on a terminal.  If so, it will set 'MAKE_TERMOUT'
-     and 'MAKE_TERMERR', respectively, to the name of the terminal
-     device (or 'true' if this cannot be determined).  If set these
-     variables will be marked for export.  These variables will not be
-     changed by 'make' and they will not be modified if already set.
-
-     These values can be used (particularly in combination with output
-     synchronization (*note Output During Parallel Execution: Parallel
-     Output.) to determine whether 'make' itself is writing to a
-     terminal; they can be tested to decide whether to force recipe
-     commands to generate colorized output for example.
-
-     If you invoke a sub-'make' and redirect its stdout or stderr it is
-     your responsibility to reset or unexport these variables as well,
-     if your makefiles rely on them.
-
-'.RECIPEPREFIX'
-     The first character of the value of this variable is used as the
-     character make assumes is introducing a recipe line.  If the
-     variable is empty (as it is by default) that character is the
-     standard tab character.  For example, this is a valid makefile:
-
-          .RECIPEPREFIX = >
-          all:
-          > @echo Hello, world
-
-     The value of '.RECIPEPREFIX' can be changed multiple times; once
-     set it stays in effect for all rules parsed until it is modified.
-
-'.VARIABLES'
-     Expands to a list of the _names_ of all global variables defined so
-     far.  This includes variables which have empty values, as well as
-     built-in variables (*note Variables Used by Implicit Rules:
-     Implicit Variables.), but does not include any variables which are
-     only defined in a target-specific context.  Note that any value you
-     assign to this variable will be ignored; it will always return its
-     special value.
-
-'.FEATURES'
-     Expands to a list of special features supported by this version of
-     'make'.  Possible values include, but are not limited to:
-
-     'archives'
-          Supports 'ar' (archive) files using special file name syntax.
-          *Note Using 'make' to Update Archive Files: Archives.
-
-     'check-symlink'
-          Supports the '-L' ('--check-symlink-times') flag.  *Note
-          Summary of Options: Options Summary.
-
-     'else-if'
-          Supports "else if" non-nested conditionals.  *Note Syntax of
-          Conditionals: Conditional Syntax.
-
-     'jobserver'
-          Supports "job server" enhanced parallel builds.  *Note
-          Parallel Execution: Parallel.
-
-     'oneshell'
-          Supports the '.ONESHELL' special target.  *Note Using One
-          Shell: One Shell.
-
-     'order-only'
-          Supports order-only prerequisites.  *Note Types of
-          Prerequisites: Prerequisite Types.
-
-     'second-expansion'
-          Supports secondary expansion of prerequisite lists.
-
-     'shortest-stem'
-          Uses the "shortest stem" method of choosing which pattern, of
-          multiple applicable options, will be used.  *Note How Patterns
-          Match: Pattern Match.
-
-     'target-specific'
-          Supports target-specific and pattern-specific variable
-          assignments.  *Note Target-specific Variable Values:
-          Target-specific.
-
-     'undefine'
-          Supports the 'undefine' directive.  *Note Undefine
-          Directive::.
-
-     'guile'
-          Has GNU Guile available as an embedded extension language.
-          *Note GNU Guile Integration: Guile Integration.
-
-     'load'
-          Supports dynamically loadable objects for creating custom
-          extensions.  *Note Loading Dynamic Objects: Loading Objects.
-
-'.INCLUDE_DIRS'
-     Expands to a list of directories that 'make' searches for included
-     makefiles (*note Including Other Makefiles: Include.).
-
-'.EXTRA_PREREQS'
-     Each word in this variable is a new prerequisite which is added to
-     targets for which it is set.  These prerequisites differ from
-     normal prerequisites in that they do not appear in any of the
-     automatic variables (*note Automatic Variables::).  This allows
-     prerequisites to be defined which do not impact the recipe.
-
-     Consider a rule to link a program:
-
-          myprog: myprog.o file1.o file2.o
-                 $(CC) $(CFLAGS) $(LDFLAGS) -o $@ $^ $(LDLIBS)
-
-     Now suppose you want to enhance this makefile to ensure that
-     updates to the compiler cause the program to be re-linked.  You can
-     add the compiler as a prerequisite, but you must ensure that it's
-     not passed as an argument to link command.  You'll need something
-     like this:
-
-          myprog: myprog.o file1.o file2.o $(CC)
-                 $(CC) $(CFLAGS) $(LDFLAGS) -o $@ $(filter-out $(CC),$^) $(LDLIBS)
-
-     Then consider having multiple extra prerequisites: they would all
-     have to be filtered out.  Using '.EXTRA_PREREQS' and
-     target-specific variables provides a simpler solution:
-
-          myprog: myprog.o file1.o file2.o
-                 $(CC) $(CFLAGS) $(LDFLAGS) -o $@ $^ $(LDLIBS)
-          myprog: .EXTRA_PREREQS = $(CC)
-
-     This feature can also be useful if you want to add prerequisites to
-     a makefile you cannot easily modify: you can create a new file such
-     as 'extra.mk':
-
-          myprog: .EXTRA_PREREQS = $(CC)
-
-     then invoke 'make -f extra.mk -f Makefile'.
-
-     Setting '.EXTRA_PREREQS' globally will cause those prerequisites to
-     be added to all targets (which did not themselves override it with
-     a target-specific value).  Note 'make' is smart enough not to add a
-     prerequisite listed in '.EXTRA_PREREQS' as a prerequisite to
-     itself.

-7 Conditional Parts of Makefiles
-********************************
-
-A "conditional" directive causes part of a makefile to be obeyed or
-ignored depending on the values of variables.  Conditionals can compare
-the value of one variable to another, or the value of a variable to a
-constant string.  Conditionals control what 'make' actually "sees" in
-the makefile, so they _cannot_ be used to control recipes at the time of
-execution.

-7.1 Example of a Conditional
-============================
-
-The following example of a conditional tells 'make' to use one set of
-libraries if the 'CC' variable is 'gcc', and a different set of
-libraries otherwise.  It works by controlling which of two recipe lines
-will be used for the rule.  The result is that 'CC=gcc' as an argument
-to 'make' changes not only which compiler is used but also which
-libraries are linked.
-
-     libs_for_gcc = -lgnu
-     normal_libs =
-
-     foo: $(objects)
-     ifeq ($(CC),gcc)
-             $(CC) -o foo $(objects) $(libs_for_gcc)
-     else
-             $(CC) -o foo $(objects) $(normal_libs)
-     endif
-
-   This conditional uses three directives: one 'ifeq', one 'else' and
-one 'endif'.
-
-   The 'ifeq' directive begins the conditional, and specifies the
-condition.  It contains two arguments, separated by a comma and
-surrounded by parentheses.  Variable substitution is performed on both
-arguments and then they are compared.  The lines of the makefile
-following the 'ifeq' are obeyed if the two arguments match; otherwise
-they are ignored.
-
-   The 'else' directive causes the following lines to be obeyed if the
-previous conditional failed.  In the example above, this means that the
-second alternative linking command is used whenever the first
-alternative is not used.  It is optional to have an 'else' in a
-conditional.
-
-   The 'endif' directive ends the conditional.  Every conditional must
-end with an 'endif'.  Unconditional makefile text follows.
-
-   As this example illustrates, conditionals work at the textual level:
-the lines of the conditional are treated as part of the makefile, or
-ignored, according to the condition.  This is why the larger syntactic
-units of the makefile, such as rules, may cross the beginning or the end
-of the conditional.
-
-   When the variable 'CC' has the value 'gcc', the above example has
-this effect:
-
-     foo: $(objects)
-             $(CC) -o foo $(objects) $(libs_for_gcc)
-
-When the variable 'CC' has any other value, the effect is this:
-
-     foo: $(objects)
-             $(CC) -o foo $(objects) $(normal_libs)
-
-   Equivalent results can be obtained in another way by conditionalizing
-a variable assignment and then using the variable unconditionally:
-
-     libs_for_gcc = -lgnu
-     normal_libs =
-
-     ifeq ($(CC),gcc)
-       libs=$(libs_for_gcc)
-     else
-       libs=$(normal_libs)
-     endif
-
-     foo: $(objects)
-             $(CC) -o foo $(objects) $(libs)

-7.2 Syntax of Conditionals
-==========================
-
-The syntax of a simple conditional with no 'else' is as follows:
-
-     CONDITIONAL-DIRECTIVE
-     TEXT-IF-TRUE
-     endif
-
-The TEXT-IF-TRUE may be any lines of text, to be considered as part of
-the makefile if the condition is true.  If the condition is false, no
-text is used instead.
-
-   The syntax of a complex conditional is as follows:
-
-     CONDITIONAL-DIRECTIVE
-     TEXT-IF-TRUE
-     else
-     TEXT-IF-FALSE
-     endif
-
-   or:
-
-     CONDITIONAL-DIRECTIVE-ONE
-     TEXT-IF-ONE-IS-TRUE
-     else CONDITIONAL-DIRECTIVE-TWO
-     TEXT-IF-TWO-IS-TRUE
-     else
-     TEXT-IF-ONE-AND-TWO-ARE-FALSE
-     endif
-
-There can be as many "'else' CONDITIONAL-DIRECTIVE" clauses as
-necessary.  Once a given condition is true, TEXT-IF-TRUE is used and no
-other clause is used; if no condition is true then TEXT-IF-FALSE is
-used.  The TEXT-IF-TRUE and TEXT-IF-FALSE can be any number of lines of
-text.
-
-   The syntax of the CONDITIONAL-DIRECTIVE is the same whether the
-conditional is simple or complex; after an 'else' or not.  There are
-four different directives that test different conditions.  Here is a
-table of them:
-
-'ifeq (ARG1, ARG2)'
-'ifeq 'ARG1' 'ARG2''
-'ifeq "ARG1" "ARG2"'
-'ifeq "ARG1" 'ARG2''
-'ifeq 'ARG1' "ARG2"'
-     Expand all variable references in ARG1 and ARG2 and compare them.
-     If they are identical, the TEXT-IF-TRUE is effective; otherwise,
-     the TEXT-IF-FALSE, if any, is effective.
-
-     Often you want to test if a variable has a non-empty value.  When
-     the value results from complex expansions of variables and
-     functions, expansions you would consider empty may actually contain
-     whitespace characters and thus are not seen as empty.  However, you
-     can use the 'strip' function (*note Text Functions::) to avoid
-     interpreting whitespace as a non-empty value.  For example:
-
-          ifeq ($(strip $(foo)),)
-          TEXT-IF-EMPTY
-          endif
-
-     will evaluate TEXT-IF-EMPTY even if the expansion of '$(foo)'
-     contains whitespace characters.
-
-'ifneq (ARG1, ARG2)'
-'ifneq 'ARG1' 'ARG2''
-'ifneq "ARG1" "ARG2"'
-'ifneq "ARG1" 'ARG2''
-'ifneq 'ARG1' "ARG2"'
-     Expand all variable references in ARG1 and ARG2 and compare them.
-     If they are different, the TEXT-IF-TRUE is effective; otherwise,
-     the TEXT-IF-FALSE, if any, is effective.
-
-'ifdef VARIABLE-NAME'
-     The 'ifdef' form takes the _name_ of a variable as its argument,
-     not a reference to a variable.  If the value of that variable has a
-     non-empty value, the TEXT-IF-TRUE is effective; otherwise, the
-     TEXT-IF-FALSE, if any, is effective.  Variables that have never
-     been defined have an empty value.  The text VARIABLE-NAME is
-     expanded, so it could be a variable or function that expands to the
-     name of a variable.  For example:
-
-          bar = true
-          foo = bar
-          ifdef $(foo)
-          frobozz = yes
-          endif
-
-     The variable reference '$(foo)' is expanded, yielding 'bar', which
-     is considered to be the name of a variable.  The variable 'bar' is
-     not expanded, but its value is examined to determine if it is
-     non-empty.
-
-     Note that 'ifdef' only tests whether a variable has a value.  It
-     does not expand the variable to see if that value is nonempty.
-     Consequently, tests using 'ifdef' return true for all definitions
-     except those like 'foo ='.  To test for an empty value, use
-     'ifeq ($(foo),)'.  For example,
-
-          bar =
-          foo = $(bar)
-          ifdef foo
-          frobozz = yes
-          else
-          frobozz = no
-          endif
-
-     sets 'frobozz' to 'yes', while:
-
-          foo =
-          ifdef foo
-          frobozz = yes
-          else
-          frobozz = no
-          endif
-
-     sets 'frobozz' to 'no'.
-
-'ifndef VARIABLE-NAME'
-     If the variable VARIABLE-NAME has an empty value, the TEXT-IF-TRUE
-     is effective; otherwise, the TEXT-IF-FALSE, if any, is effective.
-     The rules for expansion and testing of VARIABLE-NAME are identical
-     to the 'ifdef' directive.
-
-   Extra spaces are allowed and ignored at the beginning of the
-conditional directive line, but a tab is not allowed.  (If the line
-begins with a tab, it will be considered part of a recipe for a rule.)
-Aside from this, extra spaces or tabs may be inserted with no effect
-anywhere except within the directive name or within an argument.  A
-comment starting with '#' may appear at the end of the line.
-
-   The other two directives that play a part in a conditional are 'else'
-and 'endif'.  Each of these directives is written as one word, with no
-arguments.  Extra spaces are allowed and ignored at the beginning of the
-line, and spaces or tabs at the end.  A comment starting with '#' may
-appear at the end of the line.
-
-   Conditionals affect which lines of the makefile 'make' uses.  If the
-condition is true, 'make' reads the lines of the TEXT-IF-TRUE as part of
-the makefile; if the condition is false, 'make' ignores those lines
-completely.  It follows that syntactic units of the makefile, such as
-rules, may safely be split across the beginning or the end of the
-conditional.
-
-   'make' evaluates conditionals when it reads a makefile.
-Consequently, you cannot use automatic variables in the tests of
-conditionals because they are not defined until recipes are run (*note
-Automatic Variables::).
-
-   To prevent intolerable confusion, it is not permitted to start a
-conditional in one makefile and end it in another.  However, you may
-write an 'include' directive within a conditional, provided you do not
-attempt to terminate the conditional inside the included file.

-
-7.3 Conditionals that Test Flags
-================================
-
-You can write a conditional that tests 'make' command flags such as '-t'
-by using the variable 'MAKEFLAGS' together with the 'findstring'
-function (*note Functions for String Substitution and Analysis: Text
-Functions.).  This is useful when 'touch' is not enough to make a file
-appear up to date.
-
-   The 'findstring' function determines whether one string appears as a
-substring of another.  If you want to test for the '-t' flag, use 't' as
-the first string and the value of 'MAKEFLAGS' as the other.
-
-   For example, here is how to arrange to use 'ranlib -t' to finish
-marking an archive file up to date:
-
-     archive.a: ...
-     ifneq (,$(findstring t,$(MAKEFLAGS)))
-             +touch archive.a
-             +ranlib -t archive.a
-     else
-             ranlib archive.a
-     endif
-
-The '+' prefix marks those recipe lines as "recursive" so that they will
-be executed despite use of the '-t' flag.  *Note Recursive Use of
-'make': Recursion.

-8 Functions for Transforming Text
-*********************************
-
-"Functions" allow you to do text processing in the makefile to compute
-the files to operate on or the commands to use in recipes.  You use a
-function in a "function call", where you give the name of the function
-and some text (the "arguments") for the function to operate on.  The
-result of the function's processing is substituted into the makefile at
-the point of the call, just as a variable might be substituted.

-
-8.1 Function Call Syntax
-========================
-
-A function call resembles a variable reference.  It can appear anywhere
-a variable reference can appear, and it is expanded using the same rules
-as variable references.  A function call looks like this:
-
-     $(FUNCTION ARGUMENTS)
-
-or like this:
-
-     ${FUNCTION ARGUMENTS}
-
-   Here FUNCTION is a function name; one of a short list of names that
-are part of 'make'.  You can also essentially create your own functions
-by using the 'call' built-in function.
-
-   The ARGUMENTS are the arguments of the function.  They are separated
-from the function name by one or more spaces or tabs, and if there is
-more than one argument, then they are separated by commas.  Such
-whitespace and commas are not part of an argument's value.  The
-delimiters which you use to surround the function call, whether
-parentheses or braces, can appear in an argument only in matching pairs;
-the other kind of delimiters may appear singly.  If the arguments
-themselves contain other function calls or variable references, it is
-wisest to use the same kind of delimiters for all the references; write
-'$(subst a,b,$(x))', not '$(subst a,b,${x})'.  This is because it is
-clearer, and because only one type of delimiter is matched to find the
-end of the reference.
-
-   The text written for each argument is processed by substitution of
-variables and function calls to produce the argument value, which is the
-text on which the function acts.  The substitution is done in the order
-in which the arguments appear.
-
-   Commas and unmatched parentheses or braces cannot appear in the text
-of an argument as written; leading spaces cannot appear in the text of
-the first argument as written.  These characters can be put into the
-argument value by variable substitution.  First define variables 'comma'
-and 'space' whose values are isolated comma and space characters, then
-substitute these variables where such characters are wanted, like this:
-
-     comma:= ,
-     empty:=
-     space:= $(empty) $(empty)
-     foo:= a b c
-     bar:= $(subst $(space),$(comma),$(foo))
-     # bar is now 'a,b,c'.
-
-Here the 'subst' function replaces each space with a comma, through the
-value of 'foo', and substitutes the result.

-8.2 Functions for String Substitution and Analysis
-==================================================
-
-Here are some functions that operate on strings:
-
-'$(subst FROM,TO,TEXT)'
-     Performs a textual replacement on the text TEXT: each occurrence of
-     FROM is replaced by TO.  The result is substituted for the function
-     call.  For example,
-
-          $(subst ee,EE,feet on the street)
-
-     produces the value 'fEEt on the strEEt'.
-
-'$(patsubst PATTERN,REPLACEMENT,TEXT)'
-     Finds whitespace-separated words in TEXT that match PATTERN and
-     replaces them with REPLACEMENT.  Here PATTERN may contain a '%'
-     which acts as a wildcard, matching any number of any characters
-     within a word.  If REPLACEMENT also contains a '%', the '%' is
-     replaced by the text that matched the '%' in PATTERN.  Only the
-     first '%' in the PATTERN and REPLACEMENT is treated this way; any
-     subsequent '%' is unchanged.
-
-     '%' characters in 'patsubst' function invocations can be quoted
-     with preceding backslashes ('\').  Backslashes that would otherwise
-     quote '%' characters can be quoted with more backslashes.
-     Backslashes that quote '%' characters or other backslashes are
-     removed from the pattern before it is compared file names or has a
-     stem substituted into it.  Backslashes that are not in danger of
-     quoting '%' characters go unmolested.  For example, the pattern
-     'the\%weird\\%pattern\\' has 'the%weird\' preceding the operative
-     '%' character, and 'pattern\\' following it.  The final two
-     backslashes are left alone because they cannot affect any '%'
-     character.
-
-     Whitespace between words is folded into single space characters;
-     leading and trailing whitespace is discarded.
-
-     For example,
-
-          $(patsubst %.c,%.o,x.c.c bar.c)
-
-     produces the value 'x.c.o bar.o'.
-
-     Substitution references (*note Substitution References:
-     Substitution Refs.) are a simpler way to get the effect of the
-     'patsubst' function:
-
-          $(VAR:PATTERN=REPLACEMENT)
-
-     is equivalent to
-
-          $(patsubst PATTERN,REPLACEMENT,$(VAR))
-
-     The second shorthand simplifies one of the most common uses of
-     'patsubst': replacing the suffix at the end of file names.
-
-          $(VAR:SUFFIX=REPLACEMENT)
-
-     is equivalent to
-
-          $(patsubst %SUFFIX,%REPLACEMENT,$(VAR))
-
-     For example, you might have a list of object files:
-
-          objects = foo.o bar.o baz.o
-
-     To get the list of corresponding source files, you could simply
-     write:
-
-          $(objects:.o=.c)
-
-     instead of using the general form:
-
-          $(patsubst %.o,%.c,$(objects))
-
-'$(strip STRING)'
-     Removes leading and trailing whitespace from STRING and replaces
-     each internal sequence of one or more whitespace characters with a
-     single space.  Thus, '$(strip a b c )' results in 'a b c'.
-
-     The function 'strip' can be very useful when used in conjunction
-     with conditionals.  When comparing something with the empty string
-     '' using 'ifeq' or 'ifneq', you usually want a string of just
-     whitespace to match the empty string (*note Conditionals::).
-
-     Thus, the following may fail to have the desired results:
-
-          .PHONY: all
-          ifneq   "$(needs_made)" ""
-          all: $(needs_made)
-          else
-          all:;@echo 'Nothing to make!'
-          endif
-
-     Replacing the variable reference '$(needs_made)' with the function
-     call '$(strip $(needs_made))' in the 'ifneq' directive would make
-     it more robust.
-
-'$(findstring FIND,IN)'
-     Searches IN for an occurrence of FIND.  If it occurs, the value is
-     FIND; otherwise, the value is empty.  You can use this function in
-     a conditional to test for the presence of a specific substring in a
-     given string.  Thus, the two examples,
-
-          $(findstring a,a b c)
-          $(findstring a,b c)
-
-     produce the values 'a' and '' (the empty string), respectively.
-     *Note Testing Flags::, for a practical application of 'findstring'.
-
-'$(filter PATTERN...,TEXT)'
-     Returns all whitespace-separated words in TEXT that _do_ match any
-     of the PATTERN words, removing any words that _do not_ match.  The
-     patterns are written using '%', just like the patterns used in the
-     'patsubst' function above.
-
-     The 'filter' function can be used to separate out different types
-     of strings (such as file names) in a variable.  For example:
-
-          sources := foo.c bar.c baz.s ugh.h
-          foo: $(sources)
-                  cc $(filter %.c %.s,$(sources)) -o foo
-
-     says that 'foo' depends of 'foo.c', 'bar.c', 'baz.s' and 'ugh.h'
-     but only 'foo.c', 'bar.c' and 'baz.s' should be specified in the
-     command to the compiler.
-
-'$(filter-out PATTERN...,TEXT)'
-     Returns all whitespace-separated words in TEXT that _do not_ match
-     any of the PATTERN words, removing the words that _do_ match one or
-     more.  This is the exact opposite of the 'filter' function.
-
-     For example, given:
-
-          objects=main1.o foo.o main2.o bar.o
-          mains=main1.o main2.o
-
-     the following generates a list which contains all the object files
-     not in 'mains':
-
-          $(filter-out $(mains),$(objects))
-
-'$(sort LIST)'
-     Sorts the words of LIST in lexical order, removing duplicate words.
-     The output is a list of words separated by single spaces.  Thus,
-
-          $(sort foo bar lose)
-
-     returns the value 'bar foo lose'.
-
-     Incidentally, since 'sort' removes duplicate words, you can use it
-     for this purpose even if you don't care about the sort order.
-
-'$(word N,TEXT)'
-     Returns the Nth word of TEXT.  The legitimate values of N start
-     from 1.  If N is bigger than the number of words in TEXT, the value
-     is empty.  For example,
-
-          $(word 2, foo bar baz)
-
-     returns 'bar'.
-
-'$(wordlist S,E,TEXT)'
-     Returns the list of words in TEXT starting with word S and ending
-     with word E (inclusive).  The legitimate values of S start from 1;
-     E may start from 0.  If S is bigger than the number of words in
-     TEXT, the value is empty.  If E is bigger than the number of words
-     in TEXT, words up to the end of TEXT are returned.  If S is greater
-     than E, nothing is returned.  For example,
-
-          $(wordlist 2, 3, foo bar baz)
-
-     returns 'bar baz'.
-
-'$(words TEXT)'
-     Returns the number of words in TEXT.  Thus, the last word of TEXT
-     is '$(word $(words TEXT),TEXT)'.
-
-'$(firstword NAMES...)'
-     The argument NAMES is regarded as a series of names, separated by
-     whitespace.  The value is the first name in the series.  The rest
-     of the names are ignored.
-
-     For example,
-
-          $(firstword foo bar)
-
-     produces the result 'foo'.  Although '$(firstword TEXT)' is the
-     same as '$(word 1,TEXT)', the 'firstword' function is retained for
-     its simplicity.
-
-'$(lastword NAMES...)'
-     The argument NAMES is regarded as a series of names, separated by
-     whitespace.  The value is the last name in the series.
-
-     For example,
-
-          $(lastword foo bar)
-
-     produces the result 'bar'.  Although '$(lastword TEXT)' is the same
-     as '$(word $(words TEXT),TEXT)', the 'lastword' function was added
-     for its simplicity and better performance.
-
-   Here is a realistic example of the use of 'subst' and 'patsubst'.
-Suppose that a makefile uses the 'VPATH' variable to specify a list of
-directories that 'make' should search for prerequisite files (*note
-'VPATH' Search Path for All Prerequisites: General Search.).  This
-example shows how to tell the C compiler to search for header files in
-the same list of directories.
-
-   The value of 'VPATH' is a list of directories separated by colons,
-such as 'src:../headers'.  First, the 'subst' function is used to change
-the colons to spaces:
-
-     $(subst :, ,$(VPATH))
-
-This produces 'src ../headers'.  Then 'patsubst' is used to turn each
-directory name into a '-I' flag.  These can be added to the value of the
-variable 'CFLAGS', which is passed automatically to the C compiler, like
-this:
-
-     override CFLAGS += $(patsubst %,-I%,$(subst :, ,$(VPATH)))
-
-The effect is to append the text '-Isrc -I../headers' to the previously
-given value of 'CFLAGS'.  The 'override' directive is used so that the
-new value is assigned even if the previous value of 'CFLAGS' was
-specified with a command argument (*note The 'override' Directive:
-Override Directive.).

-8.3 Functions for File Names
-============================
-
-Several of the built-in expansion functions relate specifically to
-taking apart file names or lists of file names.
-
-   Each of the following functions performs a specific transformation on
-a file name.  The argument of the function is regarded as a series of
-file names, separated by whitespace.  (Leading and trailing whitespace
-is ignored.)  Each file name in the series is transformed in the same
-way and the results are concatenated with single spaces between them.
-
-'$(dir NAMES...)'
-     Extracts the directory-part of each file name in NAMES.  The
-     directory-part of the file name is everything up through (and
-     including) the last slash in it.  If the file name contains no
-     slash, the directory part is the string './'.  For example,
-
-          $(dir src/foo.c hacks)
-
-     produces the result 'src/ ./'.
-
-'$(notdir NAMES...)'
-     Extracts all but the directory-part of each file name in NAMES.  If
-     the file name contains no slash, it is left unchanged.  Otherwise,
-     everything through the last slash is removed from it.
-
-     A file name that ends with a slash becomes an empty string.  This
-     is unfortunate, because it means that the result does not always
-     have the same number of whitespace-separated file names as the
-     argument had; but we do not see any other valid alternative.
-
-     For example,
-
-          $(notdir src/foo.c hacks)
-
-     produces the result 'foo.c hacks'.
-
-'$(suffix NAMES...)'
-     Extracts the suffix of each file name in NAMES.  If the file name
-     contains a period, the suffix is everything starting with the last
-     period.  Otherwise, the suffix is the empty string.  This
-     frequently means that the result will be empty when NAMES is not,
-     and if NAMES contains multiple file names, the result may contain
-     fewer file names.
-
-     For example,
-
-          $(suffix src/foo.c src-1.0/bar.c hacks)
-
-     produces the result '.c .c'.
-
-'$(basename NAMES...)'
-     Extracts all but the suffix of each file name in NAMES.  If the
-     file name contains a period, the basename is everything starting up
-     to (and not including) the last period.  Periods in the directory
-     part are ignored.  If there is no period, the basename is the
-     entire file name.  For example,
-
-          $(basename src/foo.c src-1.0/bar hacks)
-
-     produces the result 'src/foo src-1.0/bar hacks'.
-
-'$(addsuffix SUFFIX,NAMES...)'
-     The argument NAMES is regarded as a series of names, separated by
-     whitespace; SUFFIX is used as a unit.  The value of SUFFIX is
-     appended to the end of each individual name and the resulting
-     larger names are concatenated with single spaces between them.  For
-     example,
-
-          $(addsuffix .c,foo bar)
-
-     produces the result 'foo.c bar.c'.
-
-'$(addprefix PREFIX,NAMES...)'
-     The argument NAMES is regarded as a series of names, separated by
-     whitespace; PREFIX is used as a unit.  The value of PREFIX is
-     prepended to the front of each individual name and the resulting
-     larger names are concatenated with single spaces between them.  For
-     example,
-
-          $(addprefix src/,foo bar)
-
-     produces the result 'src/foo src/bar'.
-
-'$(join LIST1,LIST2)'
-     Concatenates the two arguments word by word: the two first words
-     (one from each argument) concatenated form the first word of the
-     result, the two second words form the second word of the result,
-     and so on.  So the Nth word of the result comes from the Nth word
-     of each argument.  If one argument has more words that the other,
-     the extra words are copied unchanged into the result.
-
-     For example, '$(join a b,.c .o)' produces 'a.c b.o'.
-
-     Whitespace between the words in the lists is not preserved; it is
-     replaced with a single space.
-
-     This function can merge the results of the 'dir' and 'notdir'
-     functions, to produce the original list of files which was given to
-     those two functions.
-
-'$(wildcard PATTERN)'
-     The argument PATTERN is a file name pattern, typically containing
-     wildcard characters (as in shell file name patterns).  The result
-     of 'wildcard' is a space-separated list of the names of existing
-     files that match the pattern.  *Note Using Wildcard Characters in
-     File Names: Wildcards.
-
-'$(realpath NAMES...)'
-     For each file name in NAMES return the canonical absolute name.  A
-     canonical name does not contain any '.' or '..' components, nor any
-     repeated path separators ('/') or symlinks.  In case of a failure
-     the empty string is returned.  Consult the 'realpath(3)'
-     documentation for a list of possible failure causes.
-
-'$(abspath NAMES...)'
-     For each file name in NAMES return an absolute name that does not
-     contain any '.' or '..' components, nor any repeated path
-     separators ('/').  Note that, in contrast to 'realpath' function,
-     'abspath' does not resolve symlinks and does not require the file
-     names to refer to an existing file or directory.  Use the
-     'wildcard' function to test for existence.

-8.4 Functions for Conditionals
-==============================
-
-There are three functions that provide conditional expansion.  A key
-aspect of these functions is that not all of the arguments are expanded
-initially.  Only those arguments which need to be expanded, will be
-expanded.
-
-'$(if CONDITION,THEN-PART[,ELSE-PART])'
-     The 'if' function provides support for conditional expansion in a
-     functional context (as opposed to the GNU 'make' makefile
-     conditionals such as 'ifeq' (*note Syntax of Conditionals:
-     Conditional Syntax.)).
-
-     The first argument, CONDITION, first has all preceding and trailing
-     whitespace stripped, then is expanded.  If it expands to any
-     non-empty string, then the condition is considered to be true.  If
-     it expands to an empty string, the condition is considered to be
-     false.
-
-     If the condition is true then the second argument, THEN-PART, is
-     evaluated and this is used as the result of the evaluation of the
-     entire 'if' function.
-
-     If the condition is false then the third argument, ELSE-PART, is
-     evaluated and this is the result of the 'if' function.  If there is
-     no third argument, the 'if' function evaluates to nothing (the
-     empty string).
-
-     Note that only one of the THEN-PART or the ELSE-PART will be
-     evaluated, never both.  Thus, either can contain side-effects (such
-     as 'shell' function calls, etc.)
-
-'$(or CONDITION1[,CONDITION2[,CONDITION3...]])'
-     The 'or' function provides a "short-circuiting" OR operation.  Each
-     argument is expanded, in order.  If an argument expands to a
-     non-empty string the processing stops and the result of the
-     expansion is that string.  If, after all arguments are expanded,
-     all of them are false (empty), then the result of the expansion is
-     the empty string.
-
-'$(and CONDITION1[,CONDITION2[,CONDITION3...]])'
-     The 'and' function provides a "short-circuiting" AND operation.
-     Each argument is expanded, in order.  If an argument expands to an
-     empty string the processing stops and the result of the expansion
-     is the empty string.  If all arguments expand to a non-empty string
-     then the result of the expansion is the expansion of the last
-     argument.

-
-8.5 The 'foreach' Function
-==========================
-
-The 'foreach' function is very different from other functions.  It
-causes one piece of text to be used repeatedly, each time with a
-different substitution performed on it.  It resembles the 'for' command
-in the shell 'sh' and the 'foreach' command in the C-shell 'csh'.
-
-   The syntax of the 'foreach' function is:
-
-     $(foreach VAR,LIST,TEXT)
-
-The first two arguments, VAR and LIST, are expanded before anything else
-is done; note that the last argument, TEXT, is *not* expanded at the
-same time.  Then for each word of the expanded value of LIST, the
-variable named by the expanded value of VAR is set to that word, and
-TEXT is expanded.  Presumably TEXT contains references to that variable,
-so its expansion will be different each time.
-
-   The result is that TEXT is expanded as many times as there are
-whitespace-separated words in LIST.  The multiple expansions of TEXT are
-concatenated, with spaces between them, to make the result of 'foreach'.
-
-   This simple example sets the variable 'files' to the list of all
-files in the directories in the list 'dirs':
-
-     dirs := a b c d
-     files := $(foreach dir,$(dirs),$(wildcard $(dir)/*))
-
-   Here TEXT is '$(wildcard $(dir)/*)'.  The first repetition finds the
-value 'a' for 'dir', so it produces the same result as '$(wildcard
-a/*)'; the second repetition produces the result of '$(wildcard b/*)';
-and the third, that of '$(wildcard c/*)'.
-
-   This example has the same result (except for setting 'dirs') as the
-following example:
-
-     files := $(wildcard a/* b/* c/* d/*)
-
-   When TEXT is complicated, you can improve readability by giving it a
-name, with an additional variable:
-
-     find_files = $(wildcard $(dir)/*)
-     dirs := a b c d
-     files := $(foreach dir,$(dirs),$(find_files))
-
-Here we use the variable 'find_files' this way.  We use plain '=' to
-define a recursively-expanding variable, so that its value contains an
-actual function call to be re-expanded under the control of 'foreach'; a
-simply-expanded variable would not do, since 'wildcard' would be called
-only once at the time of defining 'find_files'.
-
-   The 'foreach' function has no permanent effect on the variable VAR;
-its value and flavor after the 'foreach' function call are the same as
-they were beforehand.  The other values which are taken from LIST are in
-effect only temporarily, during the execution of 'foreach'.  The
-variable VAR is a simply-expanded variable during the execution of
-'foreach'.  If VAR was undefined before the 'foreach' function call, it
-is undefined after the call.  *Note The Two Flavors of Variables:
-Flavors.
-
-   You must take care when using complex variable expressions that
-result in variable names because many strange things are valid variable
-names, but are probably not what you intended.  For example,
-
-     files := $(foreach Esta-escrito-en-espanol!,b c ch,$(find_files))
-
-might be useful if the value of 'find_files' references the variable
-whose name is 'Esta-escrito-en-espanol!' (es un nombre bastante largo,
-no?), but it is more likely to be a mistake.

-
-8.6 The 'file' Function
-=======================
-
-The 'file' function allows the makefile to write to or read from a file.
-Two modes of writing are supported: overwrite, where the text is written
-to the beginning of the file and any existing content is lost, and
-append, where the text is written to the end of the file, preserving the
-existing content.  In both cases the file is created if it does not
-exist.  It is a fatal error if the file cannot be opened for writing, or
-if the write operation fails.  The 'file' function expands to the empty
-string when writing to a file.
-
-   When reading from a file, the 'file' function expands to the verbatim
-contents of the file, except that the final newline (if there is one)
-will be stripped.  Attempting to read from a non-existent file expands
-to the empty string.
-
-   The syntax of the 'file' function is:
-
-     $(file OP FILENAME[,TEXT])
-
-   When the 'file' function is evaluated all its arguments are expanded
-first, then the file indicated by FILENAME will be opened in the mode
-described by OP.
-
-   The operator OP can be '>' to indicate the file will be overwritten
-with new content, '>>' to indicate the current contents of the file will
-be appended to, or '<' to indicate the contents of the file will be read
-in.  The FILENAME specifies the file to be written to or read from.
-There may optionally be whitespace between the operator and the file
-name.
-
-   When reading files, it is an error to provide a TEXT value.
-
-   When writing files, TEXT will be written to the file.  If TEXT does
-not already end in a newline a final newline will be written (even if
-TEXT is the empty string).  If the TEXT argument is not given at all,
-nothing will be written.
-
-   For example, the 'file' function can be useful if your build system
-has a limited command line size and your recipe runs a command that can
-accept arguments from a file as well.  Many commands use the convention
-that an argument prefixed with an '@' specifies a file containing more
-arguments.  Then you might write your recipe in this way:
-
-     program: $(OBJECTS)
-             $(file >$@.in,$^)
-             $(CMD) $(CMDFLAGS) @$@.in
-             @rm $@.in
-
-   If the command required each argument to be on a separate line of the
-input file, you might write your recipe like this:
-
-     program: $(OBJECTS)
-             $(file >$@.in) $(foreach O,$^,$(file >>$@.in,$O))
-             $(CMD) $(CMDFLAGS) @$@.in
-             @rm $@.in
-
-
-File: make.info,  Node: Call Function,  Next: Value Function,  Prev: File Function,  Up: Functions
-
-8.7 The 'call' Function
-=======================
-
-The 'call' function is unique in that it can be used to create new
-parameterized functions.  You can write a complex expression as the
-value of a variable, then use 'call' to expand it with different values.
-
-   The syntax of the 'call' function is:
-
-     $(call VARIABLE,PARAM,PARAM,...)
-
-   When 'make' expands this function, it assigns each PARAM to temporary
-variables '$(1)', '$(2)', etc.  The variable '$(0)' will contain
-VARIABLE.  There is no maximum number of parameter arguments.  There is
-no minimum, either, but it doesn't make sense to use 'call' with no
-parameters.
-
-   Then VARIABLE is expanded as a 'make' variable in the context of
-these temporary assignments.  Thus, any reference to '$(1)' in the value
-of VARIABLE will resolve to the first PARAM in the invocation of 'call'.
-
-   Note that VARIABLE is the _name_ of a variable, not a _reference_ to
-that variable.  Therefore you would not normally use a '$' or
-parentheses when writing it.  (You can, however, use a variable
-reference in the name if you want the name not to be a constant.)
-
-   If VARIABLE is the name of a built-in function, the built-in function
-is always invoked (even if a 'make' variable by that name also exists).
-
-   The 'call' function expands the PARAM arguments before assigning them
-to temporary variables.  This means that VARIABLE values containing
-references to built-in functions that have special expansion rules, like
-'foreach' or 'if', may not work as you expect.
-
-   Some examples may make this clearer.
-
-   This macro simply reverses its arguments:
-
-     reverse = $(2) $(1)
-
-     foo = $(call reverse,a,b)
-
-Here FOO will contain 'b a'.
-
-   This one is slightly more interesting: it defines a macro to search
-for the first instance of a program in 'PATH':
-
-     pathsearch = $(firstword $(wildcard $(addsuffix /$(1),$(subst :, ,$(PATH)))))
-
-     LS := $(call pathsearch,ls)
-
-Now the variable LS contains '/bin/ls' or similar.
-
-   The 'call' function can be nested.  Each recursive invocation gets
-its own local values for '$(1)', etc. that mask the values of
-higher-level 'call'.  For example, here is an implementation of a "map"
-function:
-
-     map = $(foreach a,$(2),$(call $(1),$(a)))
-
-   Now you can MAP a function that normally takes only one argument,
-such as 'origin', to multiple values in one step:
-
-     o = $(call map,origin,o map MAKE)
-
-   and end up with O containing something like 'file file default'.
-
-   A final caution: be careful when adding whitespace to the arguments
-to 'call'.  As with other functions, any whitespace contained in the
-second and subsequent arguments is kept; this can cause strange effects.
-It's generally safest to remove all extraneous whitespace when providing
-parameters to 'call'.

-
-8.8 The 'value' Function
-========================
-
-The 'value' function provides a way for you to use the value of a
-variable _without_ having it expanded.  Please note that this does not
-undo expansions which have already occurred; for example if you create a
-simply expanded variable its value is expanded during the definition; in
-that case the 'value' function will return the same result as using the
-variable directly.
-
-   The syntax of the 'value' function is:
-
-     $(value VARIABLE)
-
-   Note that VARIABLE is the _name_ of a variable, not a _reference_ to
-that variable.  Therefore you would not normally use a '$' or
-parentheses when writing it.  (You can, however, use a variable
-reference in the name if you want the name not to be a constant.)
-
-   The result of this function is a string containing the value of
-VARIABLE, without any expansion occurring.  For example, in this
-makefile:
-
-     FOO = $PATH
-
-     all:
-             @echo $(FOO)
-             @echo $(value FOO)
-
-The first output line would be 'ATH', since the "$P" would be expanded
-as a 'make' variable, while the second output line would be the current
-value of your '$PATH' environment variable, since the 'value' function
-avoided the expansion.
-
-   The 'value' function is most often used in conjunction with the
-'eval' function (*note Eval Function::).
-
-
-File: make.info,  Node: Eval Function,  Next: Origin Function,  Prev: Value Function,  Up: Functions
-
-8.9 The 'eval' Function
-=======================
-
-The 'eval' function is very special: it allows you to define new
-makefile constructs that are not constant; which are the result of
-evaluating other variables and functions.  The argument to the 'eval'
-function is expanded, then the results of that expansion are parsed as
-makefile syntax.  The expanded results can define new 'make' variables,
-targets, implicit or explicit rules, etc.
-
-   The result of the 'eval' function is always the empty string; thus,
-it can be placed virtually anywhere in a makefile without causing syntax
-errors.
-
-   It's important to realize that the 'eval' argument is expanded
-_twice_; first by the 'eval' function, then the results of that
-expansion are expanded again when they are parsed as makefile syntax.
-This means you may need to provide extra levels of escaping for "$"
-characters when using 'eval'.  The 'value' function (*note Value
-Function::) can sometimes be useful in these situations, to circumvent
-unwanted expansions.
-
-   Here is an example of how 'eval' can be used; this example combines a
-number of concepts and other functions.  Although it might seem overly
-complex to use 'eval' in this example, rather than just writing out the
-rules, consider two things: first, the template definition (in
-'PROGRAM_template') could need to be much more complex than it is here;
-and second, you might put the complex, "generic" part of this example
-into another makefile, then include it in all the individual makefiles.
-Now your individual makefiles are quite straightforward.
-
-     PROGRAMS    = server client
-
-     server_OBJS = server.o server_priv.o server_access.o
-     server_LIBS = priv protocol
-
-     client_OBJS = client.o client_api.o client_mem.o
-     client_LIBS = protocol

-     # Everything after this is generic

-     .PHONY: all
-     all: $(PROGRAMS)

-
-8.10 The 'origin' Function
-==========================
-
-The 'origin' function is unlike most other functions in that it does not
-operate on the values of variables; it tells you something _about_ a
-variable.  Specifically, it tells you where it came from.
-
-   The syntax of the 'origin' function is:
-
-     $(origin VARIABLE)
-
-   Note that VARIABLE is the _name_ of a variable to inquire about, not
-a _reference_ to that variable.  Therefore you would not normally use a
-'$' or parentheses when writing it.  (You can, however, use a variable
-reference in the name if you want the name not to be a constant.)
-
-   The result of this function is a string telling you how the variable
-VARIABLE was defined:
-
-'undefined'
-
-     if VARIABLE was never defined.
-
-'default'
-
-     if VARIABLE has a default definition, as is usual with 'CC' and so
-     on.  *Note Variables Used by Implicit Rules: Implicit Variables.
-     Note that if you have redefined a default variable, the 'origin'
-     function will return the origin of the later definition.
-
-'environment'
-
-     if VARIABLE was inherited from the environment provided to 'make'.
-
-'environment override'
-
-     if VARIABLE was inherited from the environment provided to 'make',
-     and is overriding a setting for VARIABLE in the makefile as a
-     result of the '-e' option (*note Summary of Options: Options
-     Summary.).
-
-'file'
-
-     if VARIABLE was defined in a makefile.
-
-'command line'
-
-     if VARIABLE was defined on the command line.
-
-'override'
-
-     if VARIABLE was defined with an 'override' directive in a makefile
-     (*note The 'override' Directive: Override Directive.).
-
-'automatic'
-
-     if VARIABLE is an automatic variable defined for the execution of
-     the recipe for each rule (*note Automatic Variables::).
-
-   This information is primarily useful (other than for your curiosity)
-to determine if you want to believe the value of a variable.  For
-example, suppose you have a makefile 'foo' that includes another
-makefile 'bar'.  You want a variable 'bletch' to be defined in 'bar' if
-you run the command 'make -f bar', even if the environment contains a
-definition of 'bletch'.  However, if 'foo' defined 'bletch' before
-including 'bar', you do not want to override that definition.  This
-could be done by using an 'override' directive in 'foo', giving that
-definition precedence over the later definition in 'bar'; unfortunately,
-the 'override' directive would also override any command line
-definitions.  So, 'bar' could include:
-
-     ifdef bletch
-     ifeq "$(origin bletch)" "environment"
-     bletch = barf, gag, etc.
-     endif
-     endif
-
-If 'bletch' has been defined from the environment, this will redefine
-it.
-
-   If you want to override a previous definition of 'bletch' if it came
-from the environment, even under '-e', you could instead write:
-
-     ifneq "$(findstring environment,$(origin bletch))" ""
-     bletch = barf, gag, etc.
-     endif
-
-   Here the redefinition takes place if '$(origin bletch)' returns
-either 'environment' or 'environment override'.  *Note Functions for
-String Substitution and Analysis: Text Functions.

-
-8.11 The 'flavor' Function
-==========================
-
-The 'flavor' function, like the 'origin' function, does not operate on
-the values of variables but rather it tells you something _about_ a
-variable.  Specifically, it tells you the flavor of a variable (*note
-The Two Flavors of Variables: Flavors.).
-
-   The syntax of the 'flavor' function is:
-
-     $(flavor VARIABLE)
-
-   Note that VARIABLE is the _name_ of a variable to inquire about, not
-a _reference_ to that variable.  Therefore you would not normally use a
-'$' or parentheses when writing it.  (You can, however, use a variable
-reference in the name if you want the name not to be a constant.)
-
-   The result of this function is a string that identifies the flavor of
-the variable VARIABLE:
-
-'undefined'
-
-     if VARIABLE was never defined.
-
-'recursive'
-
-     if VARIABLE is a recursively expanded variable.
-
-'simple'
-
-     if VARIABLE is a simply expanded variable.

-
-8.12 Functions That Control Make
-================================
-
-These functions control the way make runs.  Generally, they are used to
-provide information to the user of the makefile or to cause make to stop
-if some sort of environmental error is detected.
-
-'$(error TEXT...)'
-     Generates a fatal error where the message is TEXT.  Note that the
-     error is generated whenever this function is evaluated.  So, if you
-     put it inside a recipe or on the right side of a recursive variable
-     assignment, it won't be evaluated until later.  The TEXT will be
-     expanded before the error is generated.
-
-     For example,
-
-          ifdef ERROR1
-          $(error error is $(ERROR1))
-          endif
-
-     will generate a fatal error during the read of the makefile if the
-     'make' variable 'ERROR1' is defined.  Or,
-
-          ERR = $(error found an error!)
-
-          .PHONY: err
-          err: ; $(ERR)
-
-     will generate a fatal error while 'make' is running, if the 'err'
-     target is invoked.
-
-'$(warning TEXT...)'
-     This function works similarly to the 'error' function, above,
-     except that 'make' doesn't exit.  Instead, TEXT is expanded and the
-     resulting message is displayed, but processing of the makefile
-     continues.
-
-     The result of the expansion of this function is the empty string.
-
-'$(info TEXT...)'
-     This function does nothing more than print its (expanded)
-     argument(s) to standard output.  No makefile name or line number is
-     added.  The result of the expansion of this function is the empty
-     string.

-8.13 The 'shell' Function
-=========================
-
-The 'shell' function is unlike any other function other than the
-'wildcard' function (*note The Function 'wildcard': Wildcard Function.)
-in that it communicates with the world outside of 'make'.
-
-   The 'shell' function performs the same function that backquotes ('`')
-perform in most shells: it does "command expansion".  This means that it
-takes as an argument a shell command and evaluates to the output of the
-command.  The only processing 'make' does on the result is to convert
-each newline (or carriage-return / newline pair) to a single space.  If
-there is a trailing (carriage-return and) newline it will simply be
-removed.
-
-   The commands run by calls to the 'shell' function are run when the
-function calls are expanded (*note How 'make' Reads a Makefile: Reading
-Makefiles.).  Because this function involves spawning a new shell, you
-should carefully consider the performance implications of using the
-'shell' function within recursively expanded variables vs. simply
-expanded variables (*note The Two Flavors of Variables: Flavors.).
-
-   After the 'shell' function or '!=' assignment operator is used, its
-exit status is placed in the '.SHELLSTATUS' variable.
-
-   Here are some examples of the use of the 'shell' function:
-
-     contents := $(shell cat foo)
-
-sets 'contents' to the contents of the file 'foo', with a space (rather
-than a newline) separating each line.
-
-     files := $(shell echo *.c)
-
-sets 'files' to the expansion of '*.c'.  Unless 'make' is using a very
-strange shell, this has the same result as '$(wildcard *.c)' (as long as
-at least one '.c' file exists).
-
-
-File: make.info,  Node: Guile Function,  Prev: Shell Function,  Up: Functions
-
-8.14 The 'guile' Function
-=========================
-
-If GNU 'make' is built with support for GNU Guile as an embedded
-extension language then the 'guile' function will be available.  The
-'guile' function takes one argument which is first expanded by 'make' in
-the normal fashion, then passed to the GNU Guile evaluator.  The result
-of the evaluator is converted into a string and used as the expansion of
-the 'guile' function in the makefile.  See *note GNU Guile Integration:
-Guile Integration. for details on writing extensions to 'make' in Guile.
-
-   You can determine whether GNU Guile support is available by checking
-the '.FEATURES' variable for the word GUILE.

-9 How to Run 'make'
-*******************
-
-A makefile that says how to recompile a program can be used in more than
-one way.  The simplest use is to recompile every file that is out of
-date.  Usually, makefiles are written so that if you run 'make' with no
-arguments, it does just that.
-
-   But you might want to update only some of the files; you might want
-to use a different compiler or different compiler options; you might
-want just to find out which files are out of date without changing them.
-
-   By giving arguments when you run 'make', you can do any of these
-things and many others.
-
-   The exit status of 'make' is always one of three values:
-'0'
-     The exit status is zero if 'make' is successful.
-'2'
-     The exit status is two if 'make' encounters any errors.  It will
-     print messages describing the particular errors.
-'1'
-     The exit status is one if you use the '-q' flag and 'make'
-     determines that some target is not already up to date.  *Note

-
-9.1 Arguments to Specify the Makefile
-=====================================
-
-The way to specify the name of the makefile is with the '-f' or '--file'
-option ('--makefile' also works).  For example, '-f altmake' says to use
-the file 'altmake' as the makefile.
-
-   If you use the '-f' flag several times and follow each '-f' with an
-argument, all the specified files are used jointly as makefiles.
-
-   If you do not use the '-f' or '--file' flag, the default is to try
-'GNUmakefile', 'makefile', and 'Makefile', in that order, and use the
-first of these three which exists or can be made (*note Writing
-Makefiles: Makefiles.).
-
-
-File: make.info,  Node: Goals,  Next: Instead of Execution,  Prev: Makefile Arguments,  Up: Running
-
-9.2 Arguments to Specify the Goals
-==================================
-
-The "goals" are the targets that 'make' should strive ultimately to
-update.  Other targets are updated as well if they appear as
-prerequisites of goals, or prerequisites of prerequisites of goals, etc.
-
-   By default, the goal is the first target in the makefile (not
-counting targets that start with a period).  Therefore, makefiles are
-usually written so that the first target is for compiling the entire
-program or programs they describe.  If the first rule in the makefile
-has several targets, only the first target in the rule becomes the
-default goal, not the whole list.  You can manage the selection of the
-default goal from within your makefile using the '.DEFAULT_GOAL'
-variable (*note Other Special Variables: Special Variables.).
-
-   You can also specify a different goal or goals with command line
-arguments to 'make'.  Use the name of the goal as an argument.  If you
-specify several goals, 'make' processes each of them in turn, in the
-order you name them.
-
-   Any target in the makefile may be specified as a goal (unless it
-starts with '-' or contains an '=', in which case it will be parsed as a
-switch or variable definition, respectively).  Even targets not in the
-makefile may be specified, if 'make' can find implicit rules that say
-how to make them.
-
-   'Make' will set the special variable 'MAKECMDGOALS' to the list of
-goals you specified on the command line.  If no goals were given on the
-command line, this variable is empty.  Note that this variable should be
-used only in special circumstances.
-
-   An example of appropriate use is to avoid including '.d' files during
-'clean' rules (*note Automatic Prerequisites::), so 'make' won't create
-them only to immediately remove them again:
-
-     sources = foo.c bar.c
-
-     ifneq ($(MAKECMDGOALS),clean)
-     include $(sources:.c=.d)
-     endif
-
-   One use of specifying a goal is if you want to compile only a part of
-the program, or only one of several programs.  Specify as a goal each
-file that you wish to remake.  For example, consider a directory
-containing several programs, with a makefile that starts like this:
-
-     .PHONY: all
-     all: size nm ld ar as
-
-   If you are working on the program 'size', you might want to say
-'make size' so that only the files of that program are recompiled.
-
-   Another use of specifying a goal is to make files that are not
-normally made.  For example, there may be a file of debugging output, or
-a version of the program that is compiled specially for testing, which
-has a rule in the makefile but is not a prerequisite of the default
-goal.
-
-   Another use of specifying a goal is to run the recipe associated with
-a phony target (*note Phony Targets::) or empty target (*note Empty
-Target Files to Record Events: Empty Targets.).  Many makefiles contain
-a phony target named 'clean' which deletes everything except source
-files.  Naturally, this is done only if you request it explicitly with
-'make clean'.  Following is a list of typical phony and empty target
-names.  *Note Standard Targets::, for a detailed list of all the
-standard target names which GNU software packages use.
-
-'all'
-     Make all the top-level targets the makefile knows about.
-
-'clean'
-     Delete all files that are normally created by running 'make'.
-
-'mostlyclean'
-     Like 'clean', but may refrain from deleting a few files that people
-     normally don't want to recompile.  For example, the 'mostlyclean'
-     target for GCC does not delete 'libgcc.a', because recompiling it
-     is rarely necessary and takes a lot of time.
-
-'distclean'
-'realclean'
-'clobber'
-     Any of these targets might be defined to delete _more_ files than
-     'clean' does.  For example, this would delete configuration files
-     or links that you would normally create as preparation for
-     compilation, even if the makefile itself cannot create these files.
-
-'install'
-     Copy the executable file into a directory that users typically
-     search for commands; copy any auxiliary files that the executable
-     uses into the directories where it will look for them.
-
-'print'
-     Print listings of the source files that have changed.
-
-'tar'
-     Create a tar file of the source files.
-
-'shar'
-     Create a shell archive (shar file) of the source files.
-
-'dist'
-     Create a distribution file of the source files.  This might be a
-     tar file, or a shar file, or a compressed version of one of the
-     above, or even more than one of the above.
-
-'TAGS'
-     Update a tags table for this program.
-
-'check'
-'test'
-     Perform self tests on the program this makefile builds.

-
-9.3 Instead of Executing Recipes
-================================
-
-The makefile tells 'make' how to tell whether a target is up to date,
-and how to update each target.  But updating the targets is not always
-what you want.  Certain options specify other activities for 'make'.
-
-'-n'
-'--just-print'
-'--dry-run'
-'--recon'
-
-     "No-op".  Causes 'make' to print the recipes that are needed to
-     make the targets up to date, but not actually execute them.  Note
-     that some recipes are still executed, even with this flag (*note
-     How the 'MAKE' Variable Works: MAKE Variable.).  Also any recipes
-     needed to update included makefiles are still executed (*note How
-     Makefiles Are Remade: Remaking Makefiles.).
-
-'-t'
-'--touch'
-
-     "Touch".  Marks targets as up to date without actually changing
-     them.  In other words, 'make' pretends to update the targets but
-     does not really change their contents; instead only their modified
-     times are updated.
-
-'-q'
-'--question'
-
-     "Question".  Silently check whether the targets are up to date, but
-     do not execute recipes; the exit code shows whether any updates are
-     needed.
-
-'-W FILE'
-'--what-if=FILE'
-'--assume-new=FILE'
-'--new-file=FILE'
-
-     "What if".  Each '-W' flag is followed by a file name.  The given
-     files' modification times are recorded by 'make' as being the
-     present time, although the actual modification times remain the
-     same.  You can use the '-W' flag in conjunction with the '-n' flag
-     to see what would happen if you were to modify specific files.
-
-   With the '-n' flag, 'make' prints the recipe that it would normally
-execute but usually does not execute it.
-
-   With the '-t' flag, 'make' ignores the recipes in the rules and uses
-(in effect) the command 'touch' for each target that needs to be remade.
-The 'touch' command is also printed, unless '-s' or '.SILENT' is used.
-For speed, 'make' does not actually invoke the program 'touch'.  It does
-the work directly.
-
-   With the '-q' flag, 'make' prints nothing and executes no recipes,
-but the exit status code it returns is zero if and only if the targets
-to be considered are already up to date.  If the exit status is one,
-then some updating needs to be done.  If 'make' encounters an error, the
-exit status is two, so you can distinguish an error from a target that
-is not up to date.
-
-   It is an error to use more than one of these three flags in the same
-invocation of 'make'.
-
-   The '-n', '-t', and '-q' options do not affect recipe lines that
-begin with '+' characters or contain the strings '$(MAKE)' or '${MAKE}'.
-Note that only the line containing the '+' character or the strings
-'$(MAKE)' or '${MAKE}' is run regardless of these options.  Other lines
-in the same rule are not run unless they too begin with '+' or contain
-'$(MAKE)' or '${MAKE}' (*Note How the 'MAKE' Variable Works: MAKE
-Variable.)
-
-   The '-t' flag prevents phony targets (*note Phony Targets::) from
-being updated, unless there are recipe lines beginning with '+' or
-containing '$(MAKE)' or '${MAKE}'.
-
-   The '-W' flag provides two features:
-
-   * If you also use the '-n' or '-q' flag, you can see what 'make'
-     would do if you were to modify some files.
-
-   * Without the '-n' or '-q' flag, when 'make' is actually executing
-     recipes, the '-W' flag can direct 'make' to act as if some files
-     had been modified, without actually running the recipes for those
-     files.
-
-   Note that the options '-p' and '-v' allow you to obtain other
-information about 'make' or about the makefiles in use (*note Summary of
-Options: Options Summary.).

-
-9.4 Avoiding Recompilation of Some Files
-========================================
-
-Sometimes you may have changed a source file but you do not want to
-recompile all the files that depend on it.  For example, suppose you add
-a macro or a declaration to a header file that many other files depend
-on.  Being conservative, 'make' assumes that any change in the header
-file requires recompilation of all dependent files, but you know that
-they do not need to be recompiled and you would rather not waste the
-time waiting for them to compile.
-
-   If you anticipate the problem before changing the header file, you
-can use the '-t' flag.  This flag tells 'make' not to run the recipes in
-the rules, but rather to mark the target up to date by changing its
-last-modification date.  You would follow this procedure:
-
-  1. Use the command 'make' to recompile the source files that really
-     need recompilation, ensuring that the object files are up-to-date
-     before you begin.
-
-  2. Make the changes in the header files.
-
-  3. Use the command 'make -t' to mark all the object files as up to
-     date.  The next time you run 'make', the changes in the header
-     files will not cause any recompilation.
-
-   If you have already changed the header file at a time when some files
-do need recompilation, it is too late to do this.  Instead, you can use
-the '-o FILE' flag, which marks a specified file as "old" (*note Summary
-of Options: Options Summary.).  This means that the file itself will not
-be remade, and nothing else will be remade on its account.  Follow this
-procedure:
-
-  1. Recompile the source files that need compilation for reasons
-     independent of the particular header file, with 'make -o
-     HEADERFILE'.  If several header files are involved, use a separate
-     '-o' option for each header file.
-
-  2. Touch all the object files with 'make -t'.
-
-
-File: make.info,  Node: Overriding,  Next: Testing,  Prev: Avoiding Compilation,  Up: Running
-
-9.5 Overriding Variables
-========================
-
-An argument that contains '=' specifies the value of a variable: 'V=X'
-sets the value of the variable V to X.  If you specify a value in this
-way, all ordinary assignments of the same variable in the makefile are
-ignored; we say they have been "overridden" by the command line
-argument.
-
-   The most common way to use this facility is to pass extra flags to
-compilers.  For example, in a properly written makefile, the variable
-'CFLAGS' is included in each recipe that runs the C compiler, so a file
-'foo.c' would be compiled something like this:
-
-     cc -c $(CFLAGS) foo.c
-
-   Thus, whatever value you set for 'CFLAGS' affects each compilation
-that occurs.  The makefile probably specifies the usual value for
-'CFLAGS', like this:
-
-     CFLAGS=-g
-
-   Each time you run 'make', you can override this value if you wish.
-For example, if you say 'make CFLAGS='-g -O'', each C compilation will
-be done with 'cc -c -g -O'.  (This also illustrates how you can use
-quoting in the shell to enclose spaces and other special characters in
-the value of a variable when you override it.)
-
-   The variable 'CFLAGS' is only one of many standard variables that
-exist just so that you can change them this way.  *Note Variables Used
-by Implicit Rules: Implicit Variables, for a complete list.
-
-   You can also program the makefile to look at additional variables of
-your own, giving the user the ability to control other aspects of how
-the makefile works by changing the variables.
-
-   When you override a variable with a command line argument, you can
-define either a recursively-expanded variable or a simply-expanded
-variable.  The examples shown above make a recursively-expanded
-variable; to make a simply-expanded variable, write ':=' or '::='
-instead of '='.  But, unless you want to include a variable reference or
-function call in the _value_ that you specify, it makes no difference
-which kind of variable you create.
-
-   There is one way that the makefile can change a variable that you
-have overridden.  This is to use the 'override' directive, which is a
-line that looks like this: 'override VARIABLE = VALUE' (*note The
-'override' Directive: Override Directive.).

-9.6 Testing the Compilation of a Program
-========================================
-
-Normally, when an error happens in executing a shell command, 'make'
-gives up immediately, returning a nonzero status.  No further recipes
-are executed for any target.  The error implies that the goal cannot be
-correctly remade, and 'make' reports this as soon as it knows.
-
-   When you are compiling a program that you have just changed, this is
-not what you want.  Instead, you would rather that 'make' try compiling
-every file that can be tried, to show you as many compilation errors as
-possible.
-
-   On these occasions, you should use the '-k' or '--keep-going' flag.
-This tells 'make' to continue to consider the other prerequisites of the
-pending targets, remaking them if necessary, before it gives up and
-returns nonzero status.  For example, after an error in compiling one
-object file, 'make -k' will continue compiling other object files even
-though it already knows that linking them will be impossible.  In
-addition to continuing after failed shell commands, 'make -k' will
-continue as much as possible after discovering that it does not know how
-to make a target or prerequisite file.  This will always cause an error
-message, but without '-k', it is a fatal error (*note Summary of
-Options: Options Summary.).
-
-   The usual behavior of 'make' assumes that your purpose is to get the
-goals up to date; once 'make' learns that this is impossible, it might
-as well report the failure immediately.  The '-k' flag says that the
-real purpose is to test as much as possible of the changes made in the
-program, perhaps to find several independent problems so that you can
-correct them all before the next attempt to compile.  This is why Emacs'
-'M-x compile' command passes the '-k' flag by default.

-
-9.7 Summary of Options
-======================
-
-Here is a table of all the options 'make' understands:
-
-'-b'
-'-m'
-     These options are ignored for compatibility with other versions of
-     'make'.
-
-'-B'
-'--always-make'
-     Consider all targets out-of-date.  GNU 'make' proceeds to consider
-     targets and their prerequisites using the normal algorithms;
-     however, all targets so considered are always remade regardless of
-     the status of their prerequisites.  To avoid infinite recursion, if
-     'MAKE_RESTARTS' (*note Other Special Variables: Special Variables.)
-     is set to a number greater than 0 this option is disabled when
-     considering whether to remake makefiles (*note How Makefiles Are
-     Remade: Remaking Makefiles.).
-
-'-C DIR'
-'--directory=DIR'
-     Change to directory DIR before reading the makefiles.  If multiple
-     '-C' options are specified, each is interpreted relative to the
-     previous one: '-C / -C etc' is equivalent to '-C /etc'.  This is
-     typically used with recursive invocations of 'make' (*note
-     Recursive Use of 'make': Recursion.).
-
-'-d'
-
-     Print debugging information in addition to normal processing.  The
-     debugging information says which files are being considered for
-     remaking, which file-times are being compared and with what
-     results, which files actually need to be remade, which implicit
-     rules are considered and which are applied--everything interesting
-     about how 'make' decides what to do.  The '-d' option is equivalent
-     to '--debug=a' (see below).
-
-'--debug[=OPTIONS]'
-
-     Print debugging information in addition to normal processing.
-     Various levels and types of output can be chosen.  With no
-     arguments, print the "basic" level of debugging.  Possible
-     arguments are below; only the first character is considered, and
-     values must be comma- or space-separated.
-
-     'a (all)'
-          All types of debugging output are enabled.  This is equivalent
-          to using '-d'.
-
-     'b (basic)'
-          Basic debugging prints each target that was found to be
-          out-of-date, and whether the build was successful or not.
-
-     'v (verbose)'
-          A level above 'basic'; includes messages about which makefiles
-          were parsed, prerequisites that did not need to be rebuilt,
-          etc.  This option also enables 'basic' messages.
-
-     'i (implicit)'
-          Prints messages describing the implicit rule searches for each
-          target.  This option also enables 'basic' messages.
-
-     'j (jobs)'
-          Prints messages giving details on the invocation of specific
-          sub-commands.
-
-     'm (makefile)'
-          By default, the above messages are not enabled while trying to
-          remake the makefiles.  This option enables messages while
-          rebuilding makefiles, too.  Note that the 'all' option does
-          enable this option.  This option also enables 'basic'
-          messages.
-
-     'n (none)'
-          Disable all debugging currently enabled.  If additional
-          debugging flags are encountered after this they will still
-          take effect.
-
-'-e'
-'--environment-overrides'
-     Give variables taken from the environment precedence over variables
-     from makefiles.  *Note Variables from the Environment: Environment.
-
-'-E STRING'
-'--eval=STRING'
-
-     Evaluate STRING as makefile syntax.  This is a command-line version
-     of the 'eval' function (*note Eval Function::).  The evaluation is
-     performed after the default rules and variables have been defined,
-     but before any makefiles are read.
-
-'-f FILE'
-'--file=FILE'
-'--makefile=FILE'
-     Read the file named FILE as a makefile.  *Note Writing Makefiles:
-     Makefiles.
-
-'-h'
-'--help'
-
-     Remind you of the options that 'make' understands and then exit.
-
-'-i'
-'--ignore-errors'
-     Ignore all errors in recipes executed to remake files.  *Note
-     Errors in Recipes: Errors.
-
-'-I DIR'
-'--include-dir=DIR'
-     Specifies a directory DIR to search for included makefiles.  *Note
-     Including Other Makefiles: Include.  If several '-I' options are
-     used to specify several directories, the directories are searched
-     in the order specified.
-
-'-j [JOBS]'
-'--jobs[=JOBS]'
-     Specifies the number of recipes (jobs) to run simultaneously.  With
-     no argument, 'make' runs as many recipes simultaneously as
-     possible.  If there is more than one '-j' option, the last one is
-     effective.  *Note Parallel Execution: Parallel, for more
-     information on how recipes are run.  Note that this option is
-     ignored on MS-DOS.
-
-'-k'
-'--keep-going'
-     Continue as much as possible after an error.  While the target that
-     failed, and those that depend on it, cannot be remade, the other
-     prerequisites of these targets can be processed all the same.
-     *Note Testing the Compilation of a Program: Testing.
-
-'-l [LOAD]'
-'--load-average[=LOAD]'
-'--max-load[=LOAD]'
-     Specifies that no new recipes should be started if there are other
-     recipes running and the load average is at least LOAD (a
-     floating-point number).  With no argument, removes a previous load
-     limit.  *Note Parallel Execution: Parallel.
-
-'-L'
-'--check-symlink-times'
-     On systems that support symbolic links, this option causes 'make'
-     to consider the timestamps on any symbolic links in addition to the
-     timestamp on the file referenced by those links.  When this option
-     is provided, the most recent timestamp among the file and the
-     symbolic links is taken as the modification time for this target
-     file.
-
-'-n'
-'--just-print'
-'--dry-run'
-'--recon'
-
-     Print the recipe that would be executed, but do not execute it
-     (except in certain circumstances).  *Note Instead of Executing
-     Recipes: Instead of Execution.
-
-'-o FILE'
-'--old-file=FILE'
-'--assume-old=FILE'
-     Do not remake the file FILE even if it is older than its
-     prerequisites, and do not remake anything on account of changes in
-     FILE.  Essentially the file is treated as very old and its rules
-     are ignored.  *Note Avoiding Recompilation of Some Files: Avoiding
-     Compilation.
-
-'-O[TYPE]'
-'--output-sync[=TYPE]'
-     Ensure that the complete output from each recipe is printed in one
-     uninterrupted sequence.  This option is only useful when using the
-     '--jobs' option to run multiple recipes simultaneously (*note
-     Parallel Execution: Parallel.) Without this option output will be
-     displayed as it is generated by the recipes.
-
-     With no type or the type 'target', output from the entire recipe of
-     each target is grouped together.  With the type 'line', output from
-     each line in the recipe is grouped together.  With the type
-     'recurse', the output from an entire recursive make is grouped
-     together.  With the type 'none', no output synchronization is
-     performed.  *Note Output During Parallel Execution: Parallel
-     Output.
-
-'-p'
-'--print-data-base'
-     Print the data base (rules and variable values) that results from
-     reading the makefiles; then execute as usual or as otherwise
-     specified.  This also prints the version information given by the
-     '-v' switch (see below).  To print the data base without trying to
-     remake any files, use 'make -qp'.  To print the data base of
-     predefined rules and variables, use 'make -p -f /dev/null'.  The
-     data base output contains file name and line number information for
-     recipe and variable definitions, so it can be a useful debugging
-     tool in complex environments.
-
-'-q'
-'--question'
-     "Question mode".  Do not run any recipes, or print anything; just
-     return an exit status that is zero if the specified targets are
-     already up to date, one if any remaking is required, or two if an
-     error is encountered.  *Note Instead of Executing Recipes: Instead
-     of Execution.
-
-'-r'
-'--no-builtin-rules'
-     Eliminate use of the built-in implicit rules (*note Using Implicit
-     Rules: Implicit Rules.).  You can still define your own by writing
-     pattern rules (*note Defining and Redefining Pattern Rules: Pattern
-     Rules.).  The '-r' option also clears out the default list of
-     suffixes for suffix rules (*note Old-Fashioned Suffix Rules: Suffix
-     Rules.).  But you can still define your own suffixes with a rule
-     for '.SUFFIXES', and then define your own suffix rules.  Note that
-     only _rules_ are affected by the '-r' option; default variables
-     remain in effect (*note Variables Used by Implicit Rules: Implicit
-     Variables.); see the '-R' option below.
-
-'-R'
-'--no-builtin-variables'
-     Eliminate use of the built-in rule-specific variables (*note
-     Variables Used by Implicit Rules: Implicit Variables.).  You can
-     still define your own, of course.  The '-R' option also
-     automatically enables the '-r' option (see above), since it doesn't
-     make sense to have implicit rules without any definitions for the
-     variables that they use.
-
-'-s'
-'--silent'
-'--quiet'
-
-     Silent operation; do not print the recipes as they are executed.
-     *Note Recipe Echoing: Echoing.
-
-'-S'
-'--no-keep-going'
-'--stop'
-
-     Cancel the effect of the '-k' option.  This is never necessary
-     except in a recursive 'make' where '-k' might be inherited from the
-     top-level 'make' via 'MAKEFLAGS' (*note Recursive Use of 'make':
-     Recursion.) or if you set '-k' in 'MAKEFLAGS' in your environment.
-
-'-t'
-'--touch'
-
-     Touch files (mark them up to date without really changing them)
-     instead of running their recipes.  This is used to pretend that the
-     recipes were done, in order to fool future invocations of 'make'.
-     *Note Instead of Executing Recipes: Instead of Execution.
-
-'--trace'
-     Show tracing information for 'make' execution.  Prints the entire
-     recipe to be executed, even for recipes that are normally silent
-     (due to '.SILENT' or '@').  Also prints the makefile name and line
-     number where the recipe was defined, and information on why the
-     target is being rebuilt.
-
-'-v'
-'--version'
-     Print the version of the 'make' program plus a copyright, a list of
-     authors, and a notice that there is no warranty; then exit.
-
-'-w'
-'--print-directory'
-     Print a message containing the working directory both before and
-     after executing the makefile.  This may be useful for tracking down
-     errors from complicated nests of recursive 'make' commands.  *Note
-     Recursive Use of 'make': Recursion.  (In practice, you rarely need
-     to specify this option since 'make' does it for you; see *note The
-     '--print-directory' Option: -w Option.)
-
-'--no-print-directory'
-     Disable printing of the working directory under '-w'.  This option
-     is useful when '-w' is turned on automatically, but you do not want
-     to see the extra messages.  *Note The '--print-directory' Option:
-     -w Option.
-
-'-W FILE'
-'--what-if=FILE'
-'--new-file=FILE'
-'--assume-new=FILE'
-     Pretend that the target FILE has just been modified.  When used
-     with the '-n' flag, this shows you what would happen if you were to
-     modify that file.  Without '-n', it is almost the same as running a
-     'touch' command on the given file before running 'make', except
-     that the modification time is changed only in the imagination of
-     'make'.  *Note Instead of Executing Recipes: Instead of Execution.
-
-'--warn-undefined-variables'
-     Issue a warning message whenever 'make' sees a reference to an
-     undefined variable.  This can be helpful when you are trying to
-     debug makefiles which use variables in complex ways.

-10 Using Implicit Rules
-***********************
-
-Certain standard ways of remaking target files are used very often.  For
-example, one customary way to make an object file is from a C source
-file using the C compiler, 'cc'.
-
-   "Implicit rules" tell 'make' how to use customary techniques so that
-you do not have to specify them in detail when you want to use them.
-For example, there is an implicit rule for C compilation.  File names
-determine which implicit rules are run.  For example, C compilation
-typically takes a '.c' file and makes a '.o' file.  So 'make' applies
-the implicit rule for C compilation when it sees this combination of
-file name endings.
-
-   A chain of implicit rules can apply in sequence; for example, 'make'
-will remake a '.o' file from a '.y' file by way of a '.c' file.
-
-   The built-in implicit rules use several variables in their recipes so
-that, by changing the values of the variables, you can change the way
-the implicit rule works.  For example, the variable 'CFLAGS' controls
-the flags given to the C compiler by the implicit rule for C
-compilation.
-
-   You can define your own implicit rules by writing "pattern rules".
-
-   "Suffix rules" are a more limited way to define implicit rules.
-Pattern rules are more general and clearer, but suffix rules are
-retained for compatibility.

-10.1 Using Implicit Rules
-=========================
-
-To allow 'make' to find a customary method for updating a target file,
-all you have to do is refrain from specifying recipes yourself.  Either
-write a rule with no recipe, or don't write a rule at all.  Then 'make'
-will figure out which implicit rule to use based on which kind of source
-file exists or can be made.
-
-   For example, suppose the makefile looks like this:
-
-     foo : foo.o bar.o
-             cc -o foo foo.o bar.o $(CFLAGS) $(LDFLAGS)
-
-Because you mention 'foo.o' but do not give a rule for it, 'make' will
-automatically look for an implicit rule that tells how to update it.
-This happens whether or not the file 'foo.o' currently exists.
-
-   If an implicit rule is found, it can supply both a recipe and one or
-more prerequisites (the source files).  You would want to write a rule
-for 'foo.o' with no recipe if you need to specify additional
-prerequisites, such as header files, that the implicit rule cannot
-supply.
-
-   Each implicit rule has a target pattern and prerequisite patterns.
-There may be many implicit rules with the same target pattern.  For
-example, numerous rules make '.o' files: one, from a '.c' file with the
-C compiler; another, from a '.p' file with the Pascal compiler; and so
-on.  The rule that actually applies is the one whose prerequisites exist
-or can be made.  So, if you have a file 'foo.c', 'make' will run the C
-compiler; otherwise, if you have a file 'foo.p', 'make' will run the
-Pascal compiler; and so on.
-
-   Of course, when you write the makefile, you know which implicit rule
-you want 'make' to use, and you know it will choose that one because you
-know which possible prerequisite files are supposed to exist.  *Note
-Catalogue of Built-In Rules: Catalogue of Rules, for a catalogue of all
-the predefined implicit rules.
-
-   Above, we said an implicit rule applies if the required prerequisites
-"exist or can be made".  A file "can be made" if it is mentioned
-explicitly in the makefile as a target or a prerequisite, or if an
-implicit rule can be recursively found for how to make it.  When an
-implicit prerequisite is the result of another implicit rule, we say
-that "chaining" is occurring.  *Note Chains of Implicit Rules: Chained
-Rules.
-
-   In general, 'make' searches for an implicit rule for each target, and
-for each double-colon rule, that has no recipe.  A file that is
-mentioned only as a prerequisite is considered a target whose rule
-specifies nothing, so implicit rule search happens for it.  *Note
-Implicit Rule Search Algorithm: Implicit Rule Search, for the details of
-how the search is done.
-
-   Note that explicit prerequisites do not influence implicit rule
-search.  For example, consider this explicit rule:
-
-     foo.o: foo.p
-
-The prerequisite on 'foo.p' does not necessarily mean that 'make' will
-remake 'foo.o' according to the implicit rule to make an object file, a
-'.o' file, from a Pascal source file, a '.p' file.  For example, if
-'foo.c' also exists, the implicit rule to make an object file from a C
-source file is used instead, because it appears before the Pascal rule
-in the list of predefined implicit rules (*note Catalogue of Built-In
-Rules: Catalogue of Rules.).
-
-   If you do not want an implicit rule to be used for a target that has
-no recipe, you can give that target an empty recipe by writing a
-semicolon (*note Defining Empty Recipes: Empty Recipes.).

-
-10.2 Catalogue of Built-In Rules
-================================
-
-Here is a catalogue of predefined implicit rules which are always
-available unless the makefile explicitly overrides or cancels them.
-*Note Canceling Implicit Rules: Canceling Rules, for information on
-canceling or overriding an implicit rule.  The '-r' or
-'--no-builtin-rules' option cancels all predefined rules.
-
-   This manual only documents the default rules available on POSIX-based
-operating systems.  Other operating systems, such as VMS, Windows, OS/2,
-etc.  may have different sets of default rules.  To see the full list of
-default rules and variables available in your version of GNU 'make', run
-'make -p' in a directory with no makefile.
-
-   Not all of these rules will always be defined, even when the '-r'
-option is not given.  Many of the predefined implicit rules are
-implemented in 'make' as suffix rules, so which ones will be defined
-depends on the "suffix list" (the list of prerequisites of the special
-target '.SUFFIXES').  The default suffix list is: '.out', '.a', '.ln',
-'.o', '.c', '.cc', '.C', '.cpp', '.p', '.f', '.F', '.m', '.r', '.y',
-'.l', '.ym', '.lm', '.s', '.S', '.mod', '.sym', '.def', '.h', '.info',
-'.dvi', '.tex', '.texinfo', '.texi', '.txinfo', '.w', '.ch' '.web',
-'.sh', '.elc', '.el'.  All of the implicit rules described below whose
-prerequisites have one of these suffixes are actually suffix rules.  If
-you modify the suffix list, the only predefined suffix rules in effect
-will be those named by one or two of the suffixes that are on the list
-you specify; rules whose suffixes fail to be on the list are disabled.
-*Note Old-Fashioned Suffix Rules: Suffix Rules, for full details on
-suffix rules.
-
-Compiling C programs
-     'N.o' is made automatically from 'N.c' with a recipe of the form
-     '$(CC) $(CPPFLAGS) $(CFLAGS) -c'.
-
-Compiling C++ programs
-     'N.o' is made automatically from 'N.cc', 'N.cpp', or 'N.C' with a
-     recipe of the form '$(CXX) $(CPPFLAGS) $(CXXFLAGS) -c'.  We
-     encourage you to use the suffix '.cc' for C++ source files instead
-     of '.C'.
-
-Compiling Pascal programs
-     'N.o' is made automatically from 'N.p' with the recipe '$(PC)
-     $(PFLAGS) -c'.
-
-Compiling Fortran and Ratfor programs
-     'N.o' is made automatically from 'N.r', 'N.F' or 'N.f' by running
-     the Fortran compiler.  The precise recipe used is as follows:
-
-     '.f'
-          '$(FC) $(FFLAGS) -c'.
-     '.F'
-          '$(FC) $(FFLAGS) $(CPPFLAGS) -c'.
-     '.r'
-          '$(FC) $(FFLAGS) $(RFLAGS) -c'.
-
-Preprocessing Fortran and Ratfor programs
-     'N.f' is made automatically from 'N.r' or 'N.F'.  This rule runs
-     just the preprocessor to convert a Ratfor or preprocessable Fortran
-     program into a strict Fortran program.  The precise recipe used is
-     as follows:
-
-     '.F'
-          '$(FC) $(CPPFLAGS) $(FFLAGS) -F'.
-     '.r'
-          '$(FC) $(FFLAGS) $(RFLAGS) -F'.
-
-Compiling Modula-2 programs
-     'N.sym' is made from 'N.def' with a recipe of the form '$(M2C)
-     $(M2FLAGS) $(DEFFLAGS)'.  'N.o' is made from 'N.mod'; the form is:
-     '$(M2C) $(M2FLAGS) $(MODFLAGS)'.
-
-Assembling and preprocessing assembler programs
-     'N.o' is made automatically from 'N.s' by running the assembler,
-     'as'.  The precise recipe is '$(AS) $(ASFLAGS)'.
-
-     'N.s' is made automatically from 'N.S' by running the C
-     preprocessor, 'cpp'.  The precise recipe is '$(CPP) $(CPPFLAGS)'.
-
-Linking a single object file
-     'N' is made automatically from 'N.o' by running the linker (usually
-     called 'ld') via the C compiler.  The precise recipe used is
-     '$(CC) $(LDFLAGS) N.o $(LOADLIBES) $(LDLIBS)'.
-
-     This rule does the right thing for a simple program with only one
-     source file.  It will also do the right thing if there are multiple
-     object files (presumably coming from various other source files),
-     one of which has a name matching that of the executable file.
-     Thus,
-
-          x: y.o z.o
-
-     when 'x.c', 'y.c' and 'z.c' all exist will execute:
-
-          cc -c x.c -o x.o
-          cc -c y.c -o y.o
-          cc -c z.c -o z.o
-          cc x.o y.o z.o -o x
-          rm -f x.o
-          rm -f y.o
-          rm -f z.o
-
-     In more complicated cases, such as when there is no object file
-     whose name derives from the executable file name, you must write an
-     explicit recipe for linking.
-
-     Each kind of file automatically made into '.o' object files will be
-     automatically linked by using the compiler ('$(CC)', '$(FC)' or
-     '$(PC)'; the C compiler '$(CC)' is used to assemble '.s' files)
-     without the '-c' option.  This could be done by using the '.o'
-     object files as intermediates, but it is faster to do the compiling
-     and linking in one step, so that's how it's done.
-
-Yacc for C programs
-     'N.c' is made automatically from 'N.y' by running Yacc with the
-     recipe '$(YACC) $(YFLAGS)'.
-
-Lex for C programs
-     'N.c' is made automatically from 'N.l' by running Lex.  The actual
-     recipe is '$(LEX) $(LFLAGS)'.
-
-Lex for Ratfor programs
-     'N.r' is made automatically from 'N.l' by running Lex.  The actual
-     recipe is '$(LEX) $(LFLAGS)'.
-
-     The convention of using the same suffix '.l' for all Lex files
-     regardless of whether they produce C code or Ratfor code makes it
-     impossible for 'make' to determine automatically which of the two
-     languages you are using in any particular case.  If 'make' is
-     called upon to remake an object file from a '.l' file, it must
-     guess which compiler to use.  It will guess the C compiler, because
-     that is more common.  If you are using Ratfor, make sure 'make'
-     knows this by mentioning 'N.r' in the makefile.  Or, if you are
-     using Ratfor exclusively, with no C files, remove '.c' from the
-     list of implicit rule suffixes with:
-
-          .SUFFIXES:
-          .SUFFIXES: .o .r .f .l ...
-
-Making Lint Libraries from C, Yacc, or Lex programs
-     'N.ln' is made from 'N.c' by running 'lint'.  The precise recipe is
-     '$(LINT) $(LINTFLAGS) $(CPPFLAGS) -i'.  The same recipe is used on
-     the C code produced from 'N.y' or 'N.l'.
-
-TeX and Web
-     'N.dvi' is made from 'N.tex' with the recipe '$(TEX)'.  'N.tex' is
-     made from 'N.web' with '$(WEAVE)', or from 'N.w' (and from 'N.ch'
-     if it exists or can be made) with '$(CWEAVE)'.  'N.p' is made from
-     'N.web' with '$(TANGLE)' and 'N.c' is made from 'N.w' (and from
-     'N.ch' if it exists or can be made) with '$(CTANGLE)'.
-
-Texinfo and Info
-     'N.dvi' is made from 'N.texinfo', 'N.texi', or 'N.txinfo', with the
-     recipe '$(TEXI2DVI) $(TEXI2DVI_FLAGS)'.  'N.info' is made from
-     'N.texinfo', 'N.texi', or 'N.txinfo', with the recipe
-     '$(MAKEINFO) $(MAKEINFO_FLAGS)'.
-
-RCS
-     Any file 'N' is extracted if necessary from an RCS file named
-     either 'N,v' or 'RCS/N,v'.  The precise recipe used is
-     '$(CO) $(COFLAGS)'.  'N' will not be extracted from RCS if it
-     already exists, even if the RCS file is newer.  The rules for RCS
-     are terminal (*note Match-Anything Pattern Rules: Match-Anything
-     Rules.), so RCS files cannot be generated from another source; they
-     must actually exist.
-
-SCCS
-     Any file 'N' is extracted if necessary from an SCCS file named
-     either 's.N' or 'SCCS/s.N'.  The precise recipe used is
-     '$(GET) $(GFLAGS)'.  The rules for SCCS are terminal (*note
-     Match-Anything Pattern Rules: Match-Anything Rules.), so SCCS files
-     cannot be generated from another source; they must actually exist.
-
-     For the benefit of SCCS, a file 'N' is copied from 'N.sh' and made
-     executable (by everyone).  This is for shell scripts that are
-     checked into SCCS. Since RCS preserves the execution permission of
-     a file, you do not need to use this feature with RCS.
-
-     We recommend that you avoid using of SCCS. RCS is widely held to be
-     superior, and is also free.  By choosing free software in place of
-     comparable (or inferior) proprietary software, you support the free
-     software movement.
-
-   Usually, you want to change only the variables listed in the table
-above, which are documented in the following section.
-
-   However, the recipes in built-in implicit rules actually use
-variables such as 'COMPILE.c', 'LINK.p', and 'PREPROCESS.S', whose
-values contain the recipes listed above.
-
-   'make' follows the convention that the rule to compile a '.X' source
-file uses the variable 'COMPILE.X'.  Similarly, the rule to produce an
-executable from a '.X' file uses 'LINK.X'; and the rule to preprocess a
-'.X' file uses 'PREPROCESS.X'.
-
-   Every rule that produces an object file uses the variable
-'OUTPUT_OPTION'.  'make' defines this variable either to contain '-o
-$@', or to be empty, depending on a compile-time option.  You need the
-'-o' option to ensure that the output goes into the right file when the
-source file is in a different directory, as when using 'VPATH' (*note
-Directory Search::).  However, compilers on some systems do not accept a
-'-o' switch for object files.  If you use such a system, and use
-'VPATH', some compilations will put their output in the wrong place.  A
-possible workaround for this problem is to give 'OUTPUT_OPTION' the
-value '; mv $*.o $@'.

-10.3 Variables Used by Implicit Rules
-=====================================
-
-The recipes in built-in implicit rules make liberal use of certain
-predefined variables.  You can alter the values of these variables in
-the makefile, with arguments to 'make', or in the environment to alter
-how the implicit rules work without redefining the rules themselves.
-You can cancel all variables used by implicit rules with the '-R' or
-'--no-builtin-variables' option.
-
-   For example, the recipe used to compile a C source file actually says
-'$(CC) -c $(CFLAGS) $(CPPFLAGS)'.  The default values of the variables
-used are 'cc' and nothing, resulting in the command 'cc -c'.  By
-redefining 'CC' to 'ncc', you could cause 'ncc' to be used for all C
-compilations performed by the implicit rule.  By redefining 'CFLAGS' to
-be '-g', you could pass the '-g' option to each compilation.  _All_
-implicit rules that do C compilation use '$(CC)' to get the program name
-for the compiler and _all_ include '$(CFLAGS)' among the arguments given
-to the compiler.
-
-   The variables used in implicit rules fall into two classes: those
-that are names of programs (like 'CC') and those that contain arguments
-for the programs (like 'CFLAGS').  (The "name of a program" may also
-contain some command arguments, but it must start with an actual
-executable program name.)  If a variable value contains more than one
-argument, separate them with spaces.
-
-   The following tables describe of some of the more commonly-used
-predefined variables.  This list is not exhaustive, and the default
-values shown here may not be what 'make' selects for your environment.
-To see the complete list of predefined variables for your instance of
-GNU 'make' you can run 'make -p' in a directory with no makefiles.
-
-   Here is a table of some of the more common variables used as names of
-programs in built-in rules:
-
-'AR'

-10.4 Chains of Implicit Rules
-=============================
-
-Sometimes a file can be made by a sequence of implicit rules.  For
-example, a file 'N.o' could be made from 'N.y' by running first Yacc and
-then 'cc'.  Such a sequence is called a "chain".
-
-   If the file 'N.c' exists, or is mentioned in the makefile, no special
-searching is required: 'make' finds that the object file can be made by
-C compilation from 'N.c'; later on, when considering how to make 'N.c',
-the rule for running Yacc is used.  Ultimately both 'N.c' and 'N.o' are
-updated.
-
-   However, even if 'N.c' does not exist and is not mentioned, 'make'
-knows how to envision it as the missing link between 'N.o' and 'N.y'!
-In this case, 'N.c' is called an "intermediate file".  Once 'make' has
-decided to use the intermediate file, it is entered in the data base as
-if it had been mentioned in the makefile, along with the implicit rule
-that says how to create it.
-
-   Intermediate files are remade using their rules just like all other
-files.  But intermediate files are treated differently in two ways.
-
-   The first difference is what happens if the intermediate file does
-not exist.  If an ordinary file B does not exist, and 'make' considers a
-target that depends on B, it invariably creates B and then updates the
-target from B.  But if B is an intermediate file, then 'make' can leave
-well enough alone.  It won't bother updating B, or the ultimate target,
-unless some prerequisite of B is newer than that target or there is some
-other reason to update that target.
-
-   The second difference is that if 'make' _does_ create B in order to
-update something else, it deletes B later on after it is no longer
-needed.  Therefore, an intermediate file which did not exist before
-'make' also does not exist after 'make'.  'make' reports the deletion to
-you by printing a 'rm -f' command showing which file it is deleting.
-
-   Ordinarily, a file cannot be intermediate if it is mentioned in the
-makefile as a target or prerequisite.  However, you can explicitly mark
-a file as intermediate by listing it as a prerequisite of the special
-target '.INTERMEDIATE'.  This takes effect even if the file is mentioned
-explicitly in some other way.
-
-   You can prevent automatic deletion of an intermediate file by marking
-it as a "secondary" file.  To do this, list it as a prerequisite of the
-special target '.SECONDARY'.  When a file is secondary, 'make' will not
-create the file merely because it does not already exist, but 'make'
-does not automatically delete the file.  Marking a file as secondary
-also marks it as intermediate.
-
-   You can list the target pattern of an implicit rule (such as '%.o')
-as a prerequisite of the special target '.PRECIOUS' to preserve
-intermediate files made by implicit rules whose target patterns match
-that file's name; see *note Interrupts::.
-
-   A chain can involve more than two implicit rules.  For example, it is
-possible to make a file 'foo' from 'RCS/foo.y,v' by running RCS, Yacc
-and 'cc'.  Then both 'foo.y' and 'foo.c' are intermediate files that are
-deleted at the end.
-
-   No single implicit rule can appear more than once in a chain.  This
-means that 'make' will not even consider such a ridiculous thing as
-making 'foo' from 'foo.o.o' by running the linker twice.  This
-constraint has the added benefit of preventing any infinite loop in the
-search for an implicit rule chain.
-
-   There are some special implicit rules to optimize certain cases that
-would otherwise be handled by rule chains.  For example, making 'foo'
-from 'foo.c' could be handled by compiling and linking with separate
-chained rules, using 'foo.o' as an intermediate file.  But what actually
-happens is that a special rule for this case does the compilation and
-linking with a single 'cc' command.  The optimized rule is used in
-preference to the step-by-step chain because it comes earlier in the
-ordering of rules.
-
-   Finally, for performance reasons 'make' will not consider
-non-terminal match-anything rules (i.e., '%:') when searching for a rule
-to build a prerequisite of an implicit rule (*note Match-Anything
-Rules::).

-
-10.5 Defining and Redefining Pattern Rules
-==========================================
-
-You define an implicit rule by writing a "pattern rule".  A pattern rule
-looks like an ordinary rule, except that its target contains the
-character '%' (exactly one of them).  The target is considered a pattern
-for matching file names; the '%' can match any nonempty substring, while
-other characters match only themselves.  The prerequisites likewise use
-'%' to show how their names relate to the target name.
-
-   Thus, a pattern rule '%.o : %.c' says how to make any file 'STEM.o'
-from another file 'STEM.c'.
-
-   Note that expansion using '%' in pattern rules occurs *after* any
-variable or function expansions, which take place when the makefile is
-read.  *Note How to Use Variables: Using Variables, and *note Functions

-10.5.1 Introduction to Pattern Rules
-------------------------------------
-
-A pattern rule contains the character '%' (exactly one of them) in the
-target; otherwise, it looks exactly like an ordinary rule.  The target
-is a pattern for matching file names; the '%' matches any nonempty
-substring, while other characters match only themselves.
-
-   For example, '%.c' as a pattern matches any file name that ends in
-'.c'.  's.%.c' as a pattern matches any file name that starts with 's.',
-ends in '.c' and is at least five characters long.  (There must be at
-least one character to match the '%'.)  The substring that the '%'
-matches is called the "stem".
-
-   '%' in a prerequisite of a pattern rule stands for the same stem that
-was matched by the '%' in the target.  In order for the pattern rule to
-apply, its target pattern must match the file name under consideration
-and all of its prerequisites (after pattern substitution) must name
-files that exist or can be made.  These files become prerequisites of
-the target.
-
-   Thus, a rule of the form
-
-     %.o : %.c ; RECIPE...
-
-specifies how to make a file 'N.o', with another file 'N.c' as its
-prerequisite, provided that 'N.c' exists or can be made.
-
-   There may also be prerequisites that do not use '%'; such a
-prerequisite attaches to every file made by this pattern rule.  These
-unvarying prerequisites are useful occasionally.
-
-   A pattern rule need not have any prerequisites that contain '%', or
-in fact any prerequisites at all.  Such a rule is effectively a general
-wildcard.  It provides a way to make any file that matches the target
-pattern.  *Note Last Resort::.
-
-   More than one pattern rule may match a target.  In this case 'make'
-will choose the "best fit" rule.  *Note How Patterns Match: Pattern
-Match.
-
-   Pattern rules may have more than one target; however, every target
-must contain a '%' character.  Pattern rules are always treated as
-grouped targets (*note Multiple Targets in a Rule: Multiple Targets.)
-regardless of whether they use the ':' or '&:' separator.
-

-
-10.5.2 Pattern Rule Examples
-----------------------------
-
-Here are some examples of pattern rules actually predefined in 'make'.
-First, the rule that compiles '.c' files into '.o' files:
-
-     %.o : %.c
-             $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@
-
-defines a rule that can make any file 'X.o' from 'X.c'.  The recipe uses
-the automatic variables '$@' and '$<' to substitute the names of the
-target file and the source file in each case where the rule applies
-(*note Automatic Variables::).
-
-   Here is a second built-in rule:
-
-     % :: RCS/%,v
-             $(CO) $(COFLAGS) $<
-
-defines a rule that can make any file 'X' whatsoever from a
-corresponding file 'X,v' in the sub-directory 'RCS'.  Since the target
-is '%', this rule will apply to any file whatever, provided the
-appropriate prerequisite file exists.  The double colon makes the rule
-"terminal", which means that its prerequisite may not be an intermediate
-file (*note Match-Anything Pattern Rules: Match-Anything Rules.).
-
-   This pattern rule has two targets:
-
-     %.tab.c %.tab.h: %.y
-             bison -d $<
-
-This tells 'make' that the recipe 'bison -d X.y' will make both
-'X.tab.c' and 'X.tab.h'.  If the file 'foo' depends on the files
-'parse.tab.o' and 'scan.o' and the file 'scan.o' depends on the file
-'parse.tab.h', when 'parse.y' is changed, the recipe 'bison -d parse.y'
-will be executed only once, and the prerequisites of both 'parse.tab.o'
-and 'scan.o' will be satisfied.  (Presumably the file 'parse.tab.o' will
-be recompiled from 'parse.tab.c' and the file 'scan.o' from 'scan.c',
-while 'foo' is linked from 'parse.tab.o', 'scan.o', and its other
-prerequisites, and it will execute happily ever after.)

-
-10.5.3 Automatic Variables
---------------------------
-
-Suppose you are writing a pattern rule to compile a '.c' file into a
-'.o' file: how do you write the 'cc' command so that it operates on the
-right source file name?  You cannot write the name in the recipe,
-because the name is different each time the implicit rule is applied.
-
-   What you do is use a special feature of 'make', the "automatic
-variables".  These variables have values computed afresh for each rule
-that is executed, based on the target and prerequisites of the rule.  In
-this example, you would use '$@' for the object file name and '$<' for
-the source file name.
-
-   It's very important that you recognize the limited scope in which
-automatic variable values are available: they only have values within
-the recipe.  In particular, you cannot use them anywhere within the
-target list of a rule; they have no value there and will expand to the
-empty string.  Also, they cannot be accessed directly within the
-prerequisite list of a rule.  A common mistake is attempting to use '$@'
-within the prerequisites list; this will not work.  However, there is a
-special feature of GNU 'make', secondary expansion (*note Secondary
-Expansion::), which will allow automatic variable values to be used in
-prerequisite lists.
-
-   Here is a table of automatic variables:
-
-'$@'
-     The file name of the target of the rule.  If the target is an
-     archive member, then '$@' is the name of the archive file.  In a
-     pattern rule that has multiple targets (*note Introduction to
-     Pattern Rules: Pattern Intro.), '$@' is the name of whichever
-     target caused the rule's recipe to be run.
-
-'$%'
-     The target member name, when the target is an archive member.
-     *Note Archives::.  For example, if the target is 'foo.a(bar.o)'
-     then '$%' is 'bar.o' and '$@' is 'foo.a'.  '$%' is empty when the
-     target is not an archive member.
-
-'$<'
-     The name of the first prerequisite.  If the target got its recipe
-     from an implicit rule, this will be the first prerequisite added by
-     the implicit rule (*note Implicit Rules::).
-
-'$?'
-     The names of all the prerequisites that are newer than the target,
-     with spaces between them.  If the target does not exist, all
-     prerequisites will be included.  For prerequisites which are
-     archive members, only the named member is used (*note Archives::).
-
-'$^'
-     The names of all the prerequisites, with spaces between them.  For
-     prerequisites which are archive members, only the named member is
-     used (*note Archives::).  A target has only one prerequisite on
-     each other file it depends on, no matter how many times each file
-     is listed as a prerequisite.  So if you list a prerequisite more
-     than once for a target, the value of '$^' contains just one copy of
-     the name.  This list does *not* contain any of the order-only
-     prerequisites; for those see the '$|' variable, below.
-
-'$+'
-     This is like '$^', but prerequisites listed more than once are
-     duplicated in the order they were listed in the makefile.  This is
-     primarily useful for use in linking commands where it is meaningful
-     to repeat library file names in a particular order.
-
-'$|'
-     The names of all the order-only prerequisites, with spaces between
-     them.
-
-'$*'
-     The stem with which an implicit rule matches (*note How Patterns
-     Match: Pattern Match.).  If the target is 'dir/a.foo.b' and the
-     target pattern is 'a.%.b' then the stem is 'dir/foo'.  The stem is
-     useful for constructing names of related files.
-
-     In a static pattern rule, the stem is part of the file name that
-     matched the '%' in the target pattern.
-
-     In an explicit rule, there is no stem; so '$*' cannot be determined
-     in that way.  Instead, if the target name ends with a recognized
-     suffix (*note Old-Fashioned Suffix Rules: Suffix Rules.), '$*' is
-     set to the target name minus the suffix.  For example, if the
-     target name is 'foo.c', then '$*' is set to 'foo', since '.c' is a
-     suffix.  GNU 'make' does this bizarre thing only for compatibility
-     with other implementations of 'make'.  You should generally avoid
-     using '$*' except in implicit rules or static pattern rules.
-
-     If the target name in an explicit rule does not end with a
-     recognized suffix, '$*' is set to the empty string for that rule.
-
-   '$?' is useful even in explicit rules when you wish to operate on
-only the prerequisites that have changed.  For example, suppose that an
-archive named 'lib' is supposed to contain copies of several object
-files.  This rule copies just the changed object files into the archive:
-
-     lib: foo.o bar.o lose.o win.o
-             ar r lib $?
-
-   Of the variables listed above, four have values that are single file
-names, and three have values that are lists of file names.  These seven
-have variants that get just the file's directory name or just the file
-name within the directory.  The variant variables' names are formed by
-appending 'D' or 'F', respectively.  The functions 'dir' and 'notdir'
-can be used to obtain a similar effect (*note Functions for File Names:
-File Name Functions.).  Note, however, that the 'D' variants all omit
-the trailing slash which always appears in the output of the 'dir'
-function.  Here is a table of the variants:
-
-'$(@D)'
-     The directory part of the file name of the target, with the
-     trailing slash removed.  If the value of '$@' is 'dir/foo.o' then
-     '$(@D)' is 'dir'.  This value is '.' if '$@' does not contain a
-     slash.
-
-'$(@F)'
-     The file-within-directory part of the file name of the target.  If
-     the value of '$@' is 'dir/foo.o' then '$(@F)' is 'foo.o'.  '$(@F)'
-     is equivalent to '$(notdir $@)'.
-
-'$(*D)'
-'$(*F)'
-     The directory part and the file-within-directory part of the stem;
-     'dir' and 'foo' in this example.
-
-'$(%D)'
-'$(%F)'
-     The directory part and the file-within-directory part of the target
-     archive member name.  This makes sense only for archive member
-     targets of the form 'ARCHIVE(MEMBER)' and is useful only when
-     MEMBER may contain a directory name.  (*Note Archive Members as
-     Targets: Archive Members.)
-
-'$(<D)'
-'$(<F)'
-     The directory part and the file-within-directory part of the first
-     prerequisite.
-
-'$(^D)'
-'$(^F)'
-     Lists of the directory parts and the file-within-directory parts of
-     all prerequisites.
-
-'$(+D)'
-'$(+F)'
-     Lists of the directory parts and the file-within-directory parts of
-     all prerequisites, including multiple instances of duplicated
-     prerequisites.
-
-'$(?D)'
-'$(?F)'
-     Lists of the directory parts and the file-within-directory parts of
-     all prerequisites that are newer than the target.
-
-   Note that we use a special stylistic convention when we talk about
-these automatic variables; we write "the value of '$<'", rather than
-"the variable '<'" as we would write for ordinary variables such as
-'objects' and 'CFLAGS'.  We think this convention looks more natural in
-this special case.  Please do not assume it has a deep significance;
-'$<' refers to the variable named '<' just as '$(CFLAGS)' refers to the
-variable named 'CFLAGS'.  You could just as well use '$(<)' in place of
-'$<'.

-10.5.4 How Patterns Match
--------------------------
-
-A target pattern is composed of a '%' between a prefix and a suffix,
-either or both of which may be empty.  The pattern matches a file name
-only if the file name starts with the prefix and ends with the suffix,
-without overlap.  The text between the prefix and the suffix is called
-the "stem".  Thus, when the pattern '%.o' matches the file name
-'test.o', the stem is 'test'.  The pattern rule prerequisites are turned
-into actual file names by substituting the stem for the character '%'.
-Thus, if in the same example one of the prerequisites is written as
-'%.c', it expands to 'test.c'.
-
-   When the target pattern does not contain a slash (and it usually does
-not), directory names in the file names are removed from the file name
-before it is compared with the target prefix and suffix.  After the
-comparison of the file name to the target pattern, the directory names,
-along with the slash that ends them, are added on to the prerequisite
-file names generated from the pattern rule's prerequisite patterns and
-the file name.  The directories are ignored only for the purpose of
-finding an implicit rule to use, not in the application of that rule.
-Thus, 'e%t' matches the file name 'src/eat', with 'src/a' as the stem.
-When prerequisites are turned into file names, the directories from the
-stem are added at the front, while the rest of the stem is substituted
-for the '%'.  The stem 'src/a' with a prerequisite pattern 'c%r' gives
-the file name 'src/car'.
-
-   A pattern rule can be used to build a given file only if there is a
-target pattern that matches the file name, _and_ all prerequisites in
-that rule either exist or can be built.  The rules you write take
-precedence over those that are built in.  Note however, that a rule
-whose prerequisites actually exist or are mentioned always takes
-priority over a rule with prerequisites that must be made by chaining
-other implicit rules.
-
-   It is possible that more than one pattern rule will meet these
-criteria.  In that case, 'make' will choose the rule with the shortest
-stem (that is, the pattern that matches most specifically).  If more
-than one pattern rule has the shortest stem, 'make' will choose the
-first one found in the makefile.
-
-   This algorithm results in more specific rules being preferred over
-more generic ones; for example:
-
-     %.o: %.c
-             $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@
-
-     %.o : %.f
-             $(COMPILE.F) $(OUTPUT_OPTION) $<
-
-     lib/%.o: lib/%.c
-             $(CC) -fPIC -c $(CFLAGS) $(CPPFLAGS) $< -o $@
-
-   Given these rules and asked to build 'bar.o' where both 'bar.c' and
-'bar.f' exist, 'make' will choose the first rule and compile 'bar.c'
-into 'bar.o'.  In the same situation where 'bar.c' does not exist, then
-'make' will choose the second rule and compile 'bar.f' into 'bar.o'.
-
-   If 'make' is asked to build 'lib/bar.o' and both 'lib/bar.c' and
-'lib/bar.f' exist, then the third rule will be chosen since the stem for
-this rule ('bar') is shorter than the stem for the first rule
-('lib/bar').  If 'lib/bar.c' does not exist then the third rule is not
-eligible and the second rule will be used, even though the stem is
-longer.

-10.5.5 Match-Anything Pattern Rules
------------------------------------
-
-When a pattern rule's target is just '%', it matches any file name
-whatever.  We call these rules "match-anything" rules.  They are very
-useful, but it can take a lot of time for 'make' to think about them,
-because it must consider every such rule for each file name listed
-either as a target or as a prerequisite.
-
-   Suppose the makefile mentions 'foo.c'.  For this target, 'make' would
-have to consider making it by linking an object file 'foo.c.o', or by C
-compilation-and-linking in one step from 'foo.c.c', or by Pascal
-compilation-and-linking from 'foo.c.p', and many other possibilities.
-
-   We know these possibilities are ridiculous since 'foo.c' is a C
-source file, not an executable.  If 'make' did consider these
-possibilities, it would ultimately reject them, because files such as
-'foo.c.o' and 'foo.c.p' would not exist.  But these possibilities are so
-numerous that 'make' would run very slowly if it had to consider them.
-
-   To gain speed, we have put various constraints on the way 'make'
-considers match-anything rules.  There are two different constraints
-that can be applied, and each time you define a match-anything rule you
-must choose one or the other for that rule.
-
-   One choice is to mark the match-anything rule as "terminal" by
-defining it with a double colon.  When a rule is terminal, it does not
-apply unless its prerequisites actually exist.  Prerequisites that could
-be made with other implicit rules are not good enough.  In other words,
-no further chaining is allowed beyond a terminal rule.
-
-   For example, the built-in implicit rules for extracting sources from
-RCS and SCCS files are terminal; as a result, if the file 'foo.c,v' does
-not exist, 'make' will not even consider trying to make it as an
-intermediate file from 'foo.c,v.o' or from 'RCS/SCCS/s.foo.c,v'.  RCS
-and SCCS files are generally ultimate source files, which should not be
-remade from any other files; therefore, 'make' can save time by not
-looking for ways to remake them.
-
-   If you do not mark the match-anything rule as terminal, then it is
-non-terminal.  A non-terminal match-anything rule cannot apply to a
-prerequisite of an implicit rule, or to a file name that indicates a
-specific type of data.  A file name indicates a specific type of data if
-some non-match-anything implicit rule target matches it.
-
-   For example, the file name 'foo.c' matches the target for the pattern
-rule '%.c : %.y' (the rule to run Yacc).  Regardless of whether this
-rule is actually applicable (which happens only if there is a file
-'foo.y'), the fact that its target matches is enough to prevent
-consideration of any non-terminal match-anything rules for the file
-'foo.c'.  Thus, 'make' will not even consider trying to make 'foo.c' as
-an executable file from 'foo.c.o', 'foo.c.c', 'foo.c.p', etc.
-
-   The motivation for this constraint is that non-terminal
-match-anything rules are used for making files containing specific types
-of data (such as executable files) and a file name with a recognized
-suffix indicates some other specific type of data (such as a C source
-file).
-
-   Special built-in dummy pattern rules are provided solely to recognize
-certain file names so that non-terminal match-anything rules will not be
-considered.  These dummy rules have no prerequisites and no recipes, and
-they are ignored for all other purposes.  For example, the built-in
-implicit rule
-
-     %.p :
-
-exists to make sure that Pascal source files such as 'foo.p' match a
-specific target pattern and thereby prevent time from being wasted
-looking for 'foo.p.o' or 'foo.p.c'.
-
-   Dummy pattern rules such as the one for '%.p' are made for every
-suffix listed as valid for use in suffix rules (*note Old-Fashioned
-Suffix Rules: Suffix Rules.).

-10.5.6 Canceling Implicit Rules
--------------------------------
-
-You can override a built-in implicit rule (or one you have defined
-yourself) by defining a new pattern rule with the same target and
-prerequisites, but a different recipe.  When the new rule is defined,
-the built-in one is replaced.  The new rule's position in the sequence
-of implicit rules is determined by where you write the new rule.
-
-   You can cancel a built-in implicit rule by defining a pattern rule
-with the same target and prerequisites, but no recipe.  For example, the
-following would cancel the rule that runs the assembler:
-
-     %.o : %.s
-
-
-File: make.info,  Node: Last Resort,  Next: Suffix Rules,  Prev: Pattern Rules,  Up: Implicit Rules
-
-10.6 Defining Last-Resort Default Rules
-=======================================
-
-You can define a last-resort implicit rule by writing a terminal
-match-anything pattern rule with no prerequisites (*note Match-Anything
-Rules::).  This is just like any other pattern rule; the only thing
-special about it is that it will match any target.  So such a rule's
-recipe is used for all targets and prerequisites that have no recipe of
-their own and for which no other implicit rule applies.
-
-   For example, when testing a makefile, you might not care if the
-source files contain real data, only that they exist.  Then you might do
-this:
-
-     %::
-             touch $@
-
-to cause all the source files needed (as prerequisites) to be created
-automatically.
-
-   You can instead define a recipe to be used for targets for which
-there are no rules at all, even ones which don't specify recipes.  You
-do this by writing a rule for the target '.DEFAULT'.  Such a rule's
-recipe is used for all prerequisites which do not appear as targets in
-any explicit rule, and for which no implicit rule applies.  Naturally,
-there is no '.DEFAULT' rule unless you write one.
-
-   If you use '.DEFAULT' with no recipe or prerequisites:
-
-     .DEFAULT:
-
-the recipe previously stored for '.DEFAULT' is cleared.  Then 'make'
-acts as if you had never defined '.DEFAULT' at all.
-
-   If you do not want a target to get the recipe from a match-anything
-pattern rule or '.DEFAULT', but you also do not want any recipe to be
-run for the target, you can give it an empty recipe (*note Defining
-Empty Recipes: Empty Recipes.).
-
-   You can use a last-resort rule to override part of another makefile.

-
-10.7 Old-Fashioned Suffix Rules
-===============================
-
-"Suffix rules" are the old-fashioned way of defining implicit rules for
-'make'.  Suffix rules are obsolete because pattern rules are more
-general and clearer.  They are supported in GNU 'make' for compatibility
-with old makefiles.  They come in two kinds: "double-suffix" and
-"single-suffix".
-
-   A double-suffix rule is defined by a pair of suffixes: the target
-suffix and the source suffix.  It matches any file whose name ends with
-the target suffix.  The corresponding implicit prerequisite is made by
-replacing the target suffix with the source suffix in the file name.  A
-two-suffix rule '.c.o' (whose target and source suffixes are '.o' and
-'.c') is equivalent to the pattern rule '%.o : %.c'.
-
-   A single-suffix rule is defined by a single suffix, which is the
-source suffix.  It matches any file name, and the corresponding implicit
-prerequisite name is made by appending the source suffix.  A
-single-suffix rule whose source suffix is '.c' is equivalent to the
-pattern rule '% : %.c'.
-
-   Suffix rule definitions are recognized by comparing each rule's
-target against a defined list of known suffixes.  When 'make' sees a
-rule whose target is a known suffix, this rule is considered a
-single-suffix rule.  When 'make' sees a rule whose target is two known
-suffixes concatenated, this rule is taken as a double-suffix rule.
-
-   For example, '.c' and '.o' are both on the default list of known
-suffixes.  Therefore, if you define a rule whose target is '.c.o',
-'make' takes it to be a double-suffix rule with source suffix '.c' and
-target suffix '.o'.  Here is the old-fashioned way to define the rule
-for compiling a C source file:
-
-     .c.o:
-             $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<
-
-   Suffix rules cannot have any prerequisites of their own.  If they
-have any, they are treated as normal files with funny names, not as
-suffix rules.  Thus, the rule:
-
-     .c.o: foo.h
-             $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<
-
-tells how to make the file '.c.o' from the prerequisite file 'foo.h',
-and is not at all like the pattern rule:
-
-     %.o: %.c foo.h
-             $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@ $<
-
-which tells how to make '.o' files from '.c' files, and makes all '.o'
-files using this pattern rule also depend on 'foo.h'.
-
-   Suffix rules with no recipe are also meaningless.  They do not remove
-previous rules as do pattern rules with no recipe (*note Canceling
-Implicit Rules: Canceling Rules.).  They simply enter the suffix or pair
-of suffixes concatenated as a target in the data base.
-
-   The known suffixes are simply the names of the prerequisites of the
-special target '.SUFFIXES'.  You can add your own suffixes by writing a
-rule for '.SUFFIXES' that adds more prerequisites, as in:
-
-     .SUFFIXES: .hack .win
-
-which adds '.hack' and '.win' to the end of the list of suffixes.
-
-   If you wish to eliminate the default known suffixes instead of just
-adding to them, write a rule for '.SUFFIXES' with no prerequisites.  By
-special dispensation, this eliminates all existing prerequisites of
-'.SUFFIXES'.  You can then write another rule to add the suffixes you
-want.  For example,
-
-     .SUFFIXES:            # Delete the default suffixes
-     .SUFFIXES: .c .o .h   # Define our suffix list
-
-   The '-r' or '--no-builtin-rules' flag causes the default list of
-suffixes to be empty.
-
-   The variable 'SUFFIXES' is defined to the default list of suffixes
-before 'make' reads any makefiles.  You can change the list of suffixes
-with a rule for the special target '.SUFFIXES', but that does not alter
-this variable.

-
-10.8 Implicit Rule Search Algorithm
-===================================
-
-Here is the procedure 'make' uses for searching for an implicit rule for
-a target T.  This procedure is followed for each double-colon rule with
-no recipe, for each target of ordinary rules none of which have a
-recipe, and for each prerequisite that is not the target of any rule.
-It is also followed recursively for prerequisites that come from
-implicit rules, in the search for a chain of rules.
-
-   Suffix rules are not mentioned in this algorithm because suffix rules
-are converted to equivalent pattern rules once the makefiles have been
-read in.
-
-   For an archive member target of the form 'ARCHIVE(MEMBER)', the
-following algorithm is run twice, first using the entire target name T,
-and second using '(MEMBER)' as the target T if the first run found no
-rule.
-
-  1. Split T into a directory part, called D, and the rest, called N.
-     For example, if T is 'src/foo.o', then D is 'src/' and N is
-     'foo.o'.
-
-  2. Make a list of all the pattern rules one of whose targets matches T
-     or N.  If the target pattern contains a slash, it is matched
-     against T; otherwise, against N.
-
-  3. If any rule in that list is _not_ a match-anything rule, or if T is
-     a prerequisite of an implicit rule, then remove all non-terminal
-     match-anything rules from the list.
-
-  4. Remove from the list all rules with no recipe.
-
-  5. For each pattern rule in the list:
-
-       a. Find the stem S, which is the nonempty part of T or N matched
-          by the '%' in the target pattern.
-
-       b. Compute the prerequisite names by substituting S for '%'; if
-          the target pattern does not contain a slash, append D to the
-          front of each prerequisite name.
-
-       c. Test whether all the prerequisites exist or ought to exist.
-          (If a file name is mentioned in the makefile as a target or as
-          an explicit prerequisite, then we say it ought to exist.)
-
-          If all prerequisites exist or ought to exist, or there are no
-          prerequisites, then this rule applies.
-
-  6. If no pattern rule has been found so far, try harder.  For each
-     pattern rule in the list:
-
-       a. If the rule is terminal, ignore it and go on to the next rule.
-
-       b. Compute the prerequisite names as before.
-
-       c. Test whether all the prerequisites exist or ought to exist.
-
-       d. For each prerequisite that does not exist, follow this
-          algorithm recursively to see if the prerequisite can be made
-          by an implicit rule.
-
-       e. If all prerequisites exist, ought to exist, or can be made by
-          implicit rules, then this rule applies.
-
-  7. If no implicit rule applies, the rule for '.DEFAULT', if any,
-     applies.  In that case, give T the same recipe that '.DEFAULT' has.
-     Otherwise, there is no recipe for T.
-
-   Once a rule that applies has been found, for each target pattern of
-the rule other than the one that matched T or N, the '%' in the pattern
-is replaced with S and the resultant file name is stored until the
-recipe to remake the target file T is executed.  After the recipe is
-executed, each of these stored file names are entered into the data base
-and marked as having been updated and having the same update status as
-the file T.
-
-   When the recipe of a pattern rule is executed for T, the automatic
-variables are set corresponding to the target and prerequisites.  *Note
-Automatic Variables::.

-11 Using 'make' to Update Archive Files

-
-11.1 Archive Members as Targets
-===============================
-
-An individual member of an archive file can be used as a target or
-prerequisite in 'make'.  You specify the member named MEMBER in archive
-file ARCHIVE as follows:
-
-     ARCHIVE(MEMBER)
-
-This construct is available only in targets and prerequisites, not in
-recipes!  Most programs that you might use in recipes do not support
-this syntax and cannot act directly on archive members.  Only 'ar' and
-other programs specifically designed to operate on archives can do so.
-Therefore, valid recipes to update an archive member target probably
-must use 'ar'.  For example, this rule says to create a member 'hack.o'
-in archive 'foolib' by copying the file 'hack.o':
-
-     foolib(hack.o) : hack.o
-             ar cr foolib hack.o
-
-   In fact, nearly all archive member targets are updated in just this
-way and there is an implicit rule to do it for you.  *Please note:* The
-'c' flag to 'ar' is required if the archive file does not already exist.
-
-   To specify several members in the same archive, you can write all the
-member names together between the parentheses.  For example:
-
-     foolib(hack.o kludge.o)
-
-is equivalent to:
-
-     foolib(hack.o) foolib(kludge.o)
-
-   You can also use shell-style wildcards in an archive member
-reference.  *Note Using Wildcard Characters in File Names: Wildcards.
-For example, 'foolib(*.o)' expands to all existing members of the
-'foolib' archive whose names end in '.o'; perhaps 'foolib(hack.o)
-foolib(kludge.o)'.

-
-11.2 Implicit Rule for Archive Member Targets
-=============================================
-
-Recall that a target that looks like 'A(M)' stands for the member named
-M in the archive file A.
-
-   When 'make' looks for an implicit rule for such a target, as a
-special feature it considers implicit rules that match '(M)', as well as
-those that match the actual target 'A(M)'.
-
-   This causes one special rule whose target is '(%)' to match.  This
-rule updates the target 'A(M)' by copying the file M into the archive.
-For example, it will update the archive member target 'foo.a(bar.o)' by
-copying the _file_ 'bar.o' into the archive 'foo.a' as a _member_ named
-'bar.o'.
-
-   When this rule is chained with others, the result is very powerful.
-Thus, 'make "foo.a(bar.o)"' (the quotes are needed to protect the '('
-and ')' from being interpreted specially by the shell) in the presence
-of a file 'bar.c' is enough to cause the following recipe to be run,
-even without a makefile:
-
-     cc -c bar.c -o bar.o
-     ar r foo.a bar.o
-     rm -f bar.o
-
-Here 'make' has envisioned the file 'bar.o' as an intermediate file.
-*Note Chains of Implicit Rules: Chained Rules.
-
-   Implicit rules such as this one are written using the automatic
-variable '$%'.  *Note Automatic Variables::.
-
-   An archive member name in an archive cannot contain a directory name,
-but it may be useful in a makefile to pretend that it does.  If you
-write an archive member target 'foo.a(dir/file.o)', 'make' will perform
-automatic updating with this recipe:
-
-     ar r foo.a dir/file.o
-
-which has the effect of copying the file 'dir/file.o' into a member
-named 'file.o'.  In connection with such usage, the automatic variables
-'%D' and '%F' may be useful.

-
-11.2.1 Updating Archive Symbol Directories
-------------------------------------------
-
-An archive file that is used as a library usually contains a special
-member named '__.SYMDEF' that contains a directory of the external
-symbol names defined by all the other members.  After you update any
-other members, you need to update '__.SYMDEF' so that it will summarize
-the other members properly.  This is done by running the 'ranlib'
-program:
-
-     ranlib ARCHIVEFILE
-
-   Normally you would put this command in the rule for the archive file,
-and make all the members of the archive file prerequisites of that rule.
-For example,
-
-     libfoo.a: libfoo.a(x.o) libfoo.a(y.o) ...
-             ranlib libfoo.a
-
-The effect of this is to update archive members 'x.o', 'y.o', etc., and
-then update the symbol directory member '__.SYMDEF' by running 'ranlib'.
-The rules for updating the members are not shown here; most likely you
-can omit them and use the implicit rule which copies files into the
-archive, as described in the preceding section.
-
-   This is not necessary when using the GNU 'ar' program, which updates
-the '__.SYMDEF' member automatically.

-
-11.3 Dangers When Using Archives
-================================
-
-It is important to be careful when using parallel execution (the '-j'
-switch; *note Parallel Execution: Parallel.) and archives.  If multiple
-'ar' commands run at the same time on the same archive file, they will
-not know about each other and can corrupt the file.
-
-   Possibly a future version of 'make' will provide a mechanism to
-circumvent this problem by serializing all recipes that operate on the
-same archive file.  But for the time being, you must either write your
-makefiles to avoid this problem in some other way, or not use '-j'.
-
-
-File: make.info,  Node: Archive Suffix Rules,  Prev: Archive Pitfalls,  Up: Archives
-
-11.4 Suffix Rules for Archive Files
-===================================
-
-You can write a special kind of suffix rule for dealing with archive
-files.  *Note Suffix Rules::, for a full explanation of suffix rules.
-Archive suffix rules are obsolete in GNU 'make', because pattern rules
-for archives are a more general mechanism (*note Archive Update::).  But
-they are retained for compatibility with other 'make's.
-
-   To write a suffix rule for archives, you simply write a suffix rule
-using the target suffix '.a' (the usual suffix for archive files).  For
-example, here is the old-fashioned suffix rule to update a library
-archive from C source files:
-
-     .c.a:
-             $(CC) $(CFLAGS) $(CPPFLAGS) -c $< -o $*.o
-             $(AR) r $@ $*.o
-             $(RM) $*.o
-
-This works just as if you had written the pattern rule:
-
-     (%.o): %.c
-             $(CC) $(CFLAGS) $(CPPFLAGS) -c $< -o $*.o
-             $(AR) r $@ $*.o
-             $(RM) $*.o
-
-   In fact, this is just what 'make' does when it sees a suffix rule
-with '.a' as the target suffix.  Any double-suffix rule '.X.a' is
-converted to a pattern rule with the target pattern '(%.o)' and a
-prerequisite pattern of '%.X'.
-
-   Since you might want to use '.a' as the suffix for some other kind of
-file, 'make' also converts archive suffix rules to pattern rules in the
-normal way (*note Suffix Rules::).  Thus a double-suffix rule '.X.a'
-produces two pattern rules: '(%.o): %.X' and '%.a: %.X'.

-12 Extending GNU 'make'
-***********************
-
-GNU 'make' provides many advanced capabilities, including many useful
-functions.  However, it does not contain a complete programming language
-and so it has limitations.  Sometimes these limitations can be overcome
-through use of the 'shell' function to invoke a separate program,
-although this can be inefficient.
-
-   In cases where the built-in capabilities of GNU 'make' are
-insufficient to your requirements there are two options for extending
-'make'.  On systems where it's provided, you can utilize GNU Guile as an
-embedded scripting language (*note GNU Guile Integration: Guile
-Integration.).  On systems which support dynamically loadable objects,
-you can write your own extension in any language (which can be compiled
-into such an object) and load it to provide extended capabilities (*note
-The 'load' Directive: load Directive.).

-GNU Guile and the Scheme language and its features is beyond the scope
-of this manual: see the documentation for GNU Guile and Scheme.
-
-   You can determine if 'make' contains support for Guile by examining
-the '.FEATURES' variable; it will contain the word GUILE if Guile
-support is available.

-   The Guile integration provides one new 'make' function: 'guile'.  The
-'guile' function takes one argument which is first expanded by 'make' in
-the normal fashion, then passed to the GNU Guile evaluator.  The result
-of the evaluator is converted into a string and used as the expansion of
-the 'guile' function in the makefile.
-
-   In addition, GNU 'make' exposes Guile procedures for use in Guile
-scripts.

-
-12.1.1 Conversion of Guile Types
---------------------------------
-
-There is only one "data type" in 'make': a string.  GNU Guile, on the
-other hand, provides a rich variety of different data types.  An
-important aspect of the interface between 'make' and GNU Guile is the
-conversion of Guile data types into 'make' strings.
-
-   This conversion is relevant in two places: when a makefile invokes
-the 'guile' function to evaluate a Guile expression, the result of that
-evaluation must be converted into a make string so it can be further
-evaluated by 'make'.  And secondly, when a Guile script invokes one of
-the procedures exported by 'make' the argument provided to the procedure
-must be converted into a string.
-
-   The conversion of Guile types into 'make' strings is as below:
-
-'#f'
-     False is converted into the empty string: in 'make' conditionals
-     the empty string is considered false.
-
-'#t'
-     True is converted to the string '#t': in 'make' conditionals any
-     non-empty string is considered true.
-
-'symbol'
-'number'
-     A symbol or number is converted into the string representation of
-     that symbol or number.
-
-'character'
-     A printable character is converted to the same character.
-
-'string'
-     A string containing only printable characters is converted to the
-     same string.
-
-'list'
-     A list is converted recursively according to the above rules.  This
-     implies that any structured list will be flattened (that is, a
-     result of ''(a b (c d) e)' will be converted to the 'make' string
-     'a b c d e').
-
-'other'
-     Any other Guile type results in an error.  In future versions of
-     'make', other Guile types may be converted.
-
-   The translation of '#f' (to the empty string) and '#t' (to the
-non-empty string '#t') is designed to allow you to use Guile boolean
-results directly as 'make' boolean conditions.  For example:
-
-     $(if $(guile (access? "myfile" R_OK)),$(info myfile exists))
-
-   As a consequence of these conversion rules you must consider the
-result of your Guile script, as that result will be converted into a
-string and parsed by 'make'.  If there is no natural result for the
-script (that is, the script exists solely for its side-effects), you
-should add '#f' as the final expression in order to avoid syntax errors
-in your makefile.

-
-12.1.2 Interfaces from Guile to 'make'
---------------------------------------
-
-In addition to the 'guile' function available in makefiles, 'make'
-exposes some procedures for use in your Guile scripts.  At startup
-'make' creates a new Guile module, 'gnu make', and exports these
-procedures as public interfaces from that module:
-
-'gmk-expand'
-     This procedure takes a single argument which is converted into a
-     string.  The string is expanded by 'make' using normal 'make'
-     expansion rules.  The result of the expansion is converted into a
-     Guile string and provided as the result of the procedure.
-
-'gmk-eval'
-     This procedure takes a single argument which is converted into a
-     string.  The string is evaluated by 'make' as if it were a
-     makefile.  This is the same capability available via the 'eval'
-     function (*note Eval Function::).  The result of the 'gmk-eval'
-     procedure is always the empty string.
-
-     Note that 'gmk-eval' is not quite the same as using 'gmk-expand'
-     with the 'eval' function: in the latter case the evaluated string
-     will be expanded _twice_; first by 'gmk-expand', then again by the
-     'eval' function.
-
-
-File: make.info,  Node: Guile Example,  Prev: Guile Interface,  Up: Guile Integration
-
-12.1.3 Example Using Guile in 'make'
-------------------------------------
-
-Here is a very simple example using GNU Guile to manage writing to a
-file.  These Guile procedures simply open a file, allow writing to the
-file (one string per line), and close the file.  Note that because we
-cannot store complex values such as Guile ports in 'make' variables,
-we'll keep the port as a global variable in the Guile interpreter.
-
-   You can create Guile functions easily using 'define'/'endef' to
-create a Guile script, then use the 'guile' function to internalize it:
-
-     define GUILEIO
-     ;; A simple Guile IO library for GNU make
-
-     (define MKPORT #f)
-
-     (define (mkopen name mode)
-       (set! MKPORT (open-file name mode))
-       #f)
-
-     (define (mkwrite s)
-       (display s MKPORT)
-       (newline MKPORT)
-       #f)
-
-     (define (mkclose)
-       (close-port MKPORT)
-       #f)
-
-     #f
-     endef
-
-     # Internalize the Guile IO functions
-     $(guile $(GUILEIO))
-
-   If you have a significant amount of Guile support code, you might
-consider keeping it in a different file (e.g., 'guileio.scm') and then
-loading it in your makefile using the 'guile' function:
-
-     $(guile (load "guileio.scm"))
-
-   An advantage to this method is that when editing 'guileio.scm', your
-editor will understand that this file contains Scheme syntax rather than
-makefile syntax.
-
-   Now you can use these Guile functions to create files.  Suppose you
-need to operate on a very large list, which cannot fit on the command
-line, but the utility you're using accepts the list as input as well:
-
-     prog: $(PREREQS)
-             @$(guile (mkopen "tmp.out" "w")) \
-              $(foreach X,$^,$(guile (mkwrite "$(X)"))) \
-              $(guile (mkclose))
-             $(LINK) < tmp.out
-
-   A more comprehensive suite of file manipulation procedures is
-possible of course.  You could, for example, maintain multiple output
-files at the same time by choosing a symbol for each one and using it as
-the key to a hash table, where the value is a port, then returning the
-symbol to be stored in a 'make' variable.

-12.2 Loading Dynamic Objects
-============================
-
-     Warning: The 'load' directive and extension capability is
-     considered a "technology preview" in this release of GNU make.  We
-     encourage you to experiment with this feature and we appreciate any
-     feedback on it.  However we cannot guarantee to maintain
-     backward-compatibility in the next release.  Consider using GNU
-     Guile instead for extending GNU make (*note The 'guile' Function:
-     Guile Function.).
-
-   Many operating systems provide a facility for dynamically loading
-compiled objects.  If your system provides this facility, GNU 'make' can
-make use of it to load dynamic objects at runtime, providing new
-capabilities which may then be invoked by your makefile.
-
-   The 'load' directive is used to load a dynamic object.  Once the
-object is loaded, a "setup" function will be invoked to allow the object
-to initialize itself and register new facilities with GNU 'make'.  A
-dynamic object might include new 'make' functions, for example, and the
-"setup" function would register them with GNU 'make''s function handling
-system.

-
-
-File: make.info,  Node: load Directive,  Next: Remaking Loaded Objects,  Prev: Loading Objects,  Up: Loading Objects
-
-12.2.1 The 'load' Directive
----------------------------
-
-Objects are loaded into GNU 'make' by placing the 'load' directive into
-your makefile.  The syntax of the 'load' directive is as follows:
-
-     load OBJECT-FILE ...
-
-   or:
-
-     load OBJECT-FILE(SYMBOL-NAME) ...
-
-   The file OBJECT-FILE is dynamically loaded by GNU 'make'.  If
-OBJECT-FILE does not include a directory path then it is first looked
-for in the current directory.  If it is not found there, or a directory
-path is included, then system-specific paths will be searched.  If the
-load fails for any reason, 'make' will print a message and exit.
-
-   If the load succeeds 'make' will invoke an initializing function.
-
-   If SYMBOL-NAME is provided, it will be used as the name of the
-initializing function.
-
-   If no SYMBOL-NAME is provided, the initializing function name is
-created by taking the base file name of OBJECT-FILE, up to the first
-character which is not a valid symbol name character (alphanumerics and
-underscores are valid symbol name characters).  To this prefix will be
-appended the suffix '_gmk_setup'.
-
-   More than one object file may be loaded with a single 'load'
-directive, and both forms of 'load' arguments may be used in the same
-directive.
-
-   The initializing function will be provided the file name and line
-number of the invocation of the 'load' operation.  It should return a
-value of type 'int', which must be '0' on failure and non-'0' on
-success.  If the return value is '-1', then GNU make will _not_ attempt
-to rebuild the object file (*note How Loaded Objects Are Remade:
-Remaking Loaded Objects.).
-
-   For example:
-
-     load ../mk_funcs.so
-
-   will load the dynamic object '../mk_funcs.so'.  After the object is
-loaded, 'make' will invoke the function (assumed to be defined by the
-shared object) 'mk_funcs_gmk_setup'.
-
-   On the other hand:
-
-     load ../mk_funcs.so(init_mk_func)
-
-   will load the dynamic object '../mk_funcs.so'.  After the object is
-loaded, 'make' will invoke the function 'init_mk_func'.
-
-   Regardless of how many times an object file appears in a 'load'
-directive, it will only be loaded (and its setup function will only be
-invoked) once.
-
-   After an object has been successfully loaded, its file name is
-appended to the '.LOADED' variable.
-
-   If you would prefer that failure to load a dynamic object not be
-reported as an error, you can use the '-load' directive instead of
-'load'.  GNU 'make' will not fail and no message will be generated if an
-object fails to load.  The failed object is not added to the '.LOADED'
-variable, which can then be consulted to determine if the load was
-successful.

-
-12.2.2 How Loaded Objects Are Remade
-------------------------------------
-
-Loaded objects undergo the same re-make procedure as makefiles (*note
-How Makefiles Are Remade: Remaking Makefiles.).  If any loaded object is
-recreated, then 'make' will start from scratch and re-read all the
-makefiles, and reload the object files again.  It is not necessary for
-the loaded object to do anything special to support this.
-
-   It's up to the makefile author to provide the rules needed for
-rebuilding the loaded object.
-
-
-File: make.info,  Node: Loaded Object API,  Next: Loaded Object Example,  Prev: Remaking Loaded Objects,  Up: Loading Objects
-
-12.2.3 Loaded Object Interface
-------------------------------
-
-     Warning: For this feature to be useful your extensions will need to
-     invoke various functions internal to GNU 'make'.  The programming
-     interfaces provided in this release should not be considered
-     stable: functions may be added, removed, or change calling
-     signatures or implementations in future versions of GNU 'make'.
-
-   To be useful, loaded objects must be able to interact with GNU
-'make'.  This interaction includes both interfaces the loaded object
-provides to makefiles and also interfaces 'make' provides to the loaded
-object to manipulate 'make''s operation.
-
-   The interface between loaded objects and 'make' is defined by the
-'gnumake.h' C header file.  All loaded objects written in C should
-include this header file.  Any loaded object not written in C will need
-to implement the interface defined in this header file.
-
-   Typically, a loaded object will register one or more new GNU 'make'
-functions using the 'gmk_add_function' routine from within its setup
-function.  The implementations of these 'make' functions may make use of
-the 'gmk_expand' and 'gmk_eval' routines to perform their tasks, then
-optionally return a string as the result of the function expansion.
-
-Loaded Object Licensing
-.......................
-
-Every dynamic extension should define the global symbol
-'plugin_is_GPL_compatible' to assert that it has been licensed under a
-GPL-compatible license.  If this symbol does not exist, 'make' emits a
-fatal error and exits when it tries to load your extension.
-
-   The declared type of the symbol should be 'int'.  It does not need to
-be in any allocated section, though.  The code merely asserts that the
-symbol exists in the global scope.  Something like this is enough:
-
-     int plugin_is_GPL_compatible;
-
-Data Structures
-...............
-
-'gmk_floc'
-     This structure represents a filename/location pair.  It is provided
-     when defining items, so GNU 'make' can inform the user later where
-     the definition occurred if necessary.
-
-Registering Functions
-.....................
-
-There is currently one way for makefiles to invoke operations provided
-by the loaded object: through the 'make' function call interface.  A
-loaded object can register one or more new functions which may then be
-invoked from within the makefile in the same way as any other function.
-
-   Use 'gmk_add_function' to create a new 'make' function.  Its
-arguments are as follows:
-
-'name'
-     The function name.  This is what the makefile should use to invoke
-     the function.  The name must be between 1 and 255 characters long
-     and it may only contain alphanumeric, period ('.'), dash ('-'), and
-     underscore ('_') characters.  It may not begin with a period.
-
-'func_ptr'
-     A pointer to a function that 'make' will invoke when it expands the
-     function in a makefile.  This function must be defined by the
-     loaded object.
-
-'min_args'
-     The minimum number of arguments the function will accept.  Must be
-     between 0 and 255.  GNU 'make' will check this and fail before
-     invoking 'func_ptr' if the function was invoked with too few
-     arguments.
-
-'max_args'
-     The maximum number of arguments the function will accept.  Must be
-     between 0 and 255.  GNU 'make' will check this and fail before
-     invoking 'func_ptr' if the function was invoked with too few
-     arguments.  If the value is 0, then any number of arguments is
-     accepted.  If the value is greater than 0, then it must be greater
-     than or equal to 'min_args'.
-
-'flags'
-     Flags that specify how this function will operate; the desired
-     flags should be OR'd together.  If the 'GMK_FUNC_NOEXPAND' flag is
-     given then the function arguments will not be expanded before the
-     function is called; otherwise they will be expanded first.
-
-Registered Function Interface
-.............................
-
-A function registered with 'make' must match the 'gmk_func_ptr' type.
-It will be invoked with three parameters: 'name' (the name of the
-function), 'argc' (the number of arguments to the function), and 'argv'
-(an array of pointers to arguments to the function).  The last pointer
-(that is, 'argv[argc]') will be null ('0').
-
-   The return value of the function is the result of expanding the
-function.  If the function expands to nothing the return value may be
-null.  Otherwise, it must be a pointer to a string created with
-'gmk_alloc'.  Once the function returns, 'make' owns this string and
-will free it when appropriate; it cannot be accessed by the loaded
-object.
-
-GNU 'make' Facilities
-.....................
-
-There are some facilities exported by GNU 'make' for use by loaded
-objects.  Typically these would be run from within the setup function
-and/or the functions registered via 'gmk_add_function', to retrieve or
-modify the data 'make' works with.
-
-'gmk_expand'
-     This function takes a string and expands it using 'make' expansion
-     rules.  The result of the expansion is returned in a nil-terminated
-     string buffer.  The caller is responsible for calling 'gmk_free'
-     with a pointer to the returned buffer when done.
-
-'gmk_eval'
-     This function takes a buffer and evaluates it as a segment of
-     makefile syntax.  This function can be used to define new
-     variables, new rules, etc.  It is equivalent to using the 'eval'
-     'make' function.
-
-   Note that there is a difference between 'gmk_eval' and calling
-'gmk_expand' with a string using the 'eval' function: in the latter case
-the string will be expanded _twice_; once by 'gmk_expand' and then again
-by the 'eval' function.  Using 'gmk_eval' the buffer is only expanded
-once, at most (as it's read by the 'make' parser).
-
-Memory Management
-.................
-
-Some systems allow for different memory management schemes.  Thus you
-should never pass memory that you've allocated directly to any 'make'
-function, nor should you attempt to directly free any memory returned to
-you by any 'make' function.  Instead, use the 'gmk_alloc' and 'gmk_free'
-functions.
-
-   In particular, the string returned to 'make' by a function registered
-using 'gmk_add_function' _must_ be allocated using 'gmk_alloc', and the
-string returned from the 'make' 'gmk_expand' function _must_ be freed
-(when no longer needed) using 'gmk_free'.
-
-'gmk_alloc'
-     Return a pointer to a newly-allocated buffer.  This function will
-     always return a valid pointer; if not enough memory is available
-     'make' will exit.
-
-'gmk_free'
-     Free a buffer returned to you by 'make'.  Once the 'gmk_free'
-     function returns the string will no longer be valid.

-12.2.4 Example Loaded Object
-----------------------------
-
-Let's suppose we wanted to write a new GNU 'make' function that would
-create a temporary file and return its name.  We would like our function
-to take a prefix as an argument.  First we can write the function in a
-file 'mk_temp.c':
-
-     #include <stdlib.h>
-     #include <stdlib.h>
-     #include <stdio.h>
-     #include <string.h>
-     #include <unistd.h>
-     #include <errno.h>
-
-     #include <gnumake.h>
-
-     int plugin_is_GPL_compatible;
-
-     char *
-     gen_tmpfile(const char *nm, int argc, char **argv)
-     {
-       int fd;
-
-       /* Compute the size of the filename and allocate space for it.  */
-       int len = strlen (argv[0]) + 6 + 1;
-       char *buf = gmk_alloc (len);
-
-       strcpy (buf, argv[0]);
-       strcat (buf, "XXXXXX");
-
-       fd = mkstemp(buf);
-       if (fd >= 0)
-         {
-           /* Don't leak the file descriptor.  */
-           close (fd);
-           return buf;
-         }
-
-       /* Failure.  */
-       fprintf (stderr, "mkstemp(%s) failed: %s\n", buf, strerror (errno));
-       gmk_free (buf);
-       return NULL;
-     }
-
-     int
-     mk_temp_gmk_setup ()
-     {
-       /* Register the function with make name "mk-temp".  */
-       gmk_add_function ("mk-temp", gen_tmpfile, 1, 1, 1);
-       return 1;
-     }
-
-   Next, we will write a makefile that can build this shared object,
-load it, and use it:
-
-     all:
-             @echo Temporary file: $(mk-temp tmpfile.)
-
-     load mk_temp.so
-
-     mk_temp.so: mk_temp.c
-             $(CC) -shared -fPIC -o $ $<
-
-   On MS-Windows, due to peculiarities of how shared objects are
-produced, the compiler needs to scan the "import library" produced when
-building 'make', typically called 'libgnumake-VERSION.dll.a', where
-VERSION is the version of the load object API. So the recipe to produce
-a shared object will look on Windows like this (assuming the API version
-is 1):
-
-     mk_temp.dll: mk_temp.c
-             $(CC) -shared -o $ $< -lgnumake-1
-
-   Now when you run 'make' you'll see something like:
-
-     $ make
-     cc -shared -fPIC -o mk_temp.so mk_temp.c
-     Temporary filename: tmpfile.A7JEwd

-13 Integrating GNU 'make'
-*************************
-
-GNU 'make' is often one component in a larger system of tools, including
-integrated development environments, compiler toolchains, and others.
-The role of 'make' is to start commands and determine whether they
-succeeded or not: no special integration is needed to accomplish that.
-However, sometimes it is convenient to bind 'make' more tightly with
-other parts of the system, both higher-level (tools that invoke 'make')
-and lower-level (tools that 'make' invokes).
-
-* Menu:
-
-* Job Slots::                   Share job slots with GNU 'make'.
-* Terminal Output::             Control output to terminals.
-
-
-File: make.info,  Node: Job Slots,  Next: Terminal Output,  Prev: Integrating make,  Up: Integrating make
-
-13.1 Sharing Job Slots with GNU 'make'
-======================================
-
-GNU 'make' has the ability to run multiple recipes in parallel (*note
-Parallel Execution: Parallel.) and to cap the total number of parallel
-jobs even across recursive invocations of 'make' (*note Communicating
-Options to a Sub-'make': Options/Recursion.).  Tools that 'make' invokes
-which are also able to run multiple operations in parallel, either using
-multiple threads or multiple processes, can be enhanced to participate
-in GNU 'make''s job management facility to ensure that the total number
-of active threads/processes running on the system does not exceed the
-maximum number of slots provided to GNU 'make'.
-
-   GNU 'make' uses a method called the "jobserver" to control the number
-of active jobs across recursive invocations.  The actual implementation
-of the jobserver varies across different operating systems, but some
-fundamental aspects are always true.
-
-   First, only command lines that 'make' understands to be recursive
-invocations of 'make' (*note How the 'MAKE' Variable Works: MAKE
-Variable.) will have access to the jobserver.  When writing makefiles
-you must be sure to mark the command as recursive (most commonly by
-prefixing the command line with the '+' indicator (*note Recursive Use
-of 'make': Recursion.).
-
-   Second, 'make' will provide information necessary for accessing the
-jobserver through the environment to its children, in the 'MAKEFLAGS'
-environment variable.  Tools which want to participate in the jobserver
-protocol will need to parse this environment variable, as described in
-subsequent sections.
-
-   Third, every command 'make' starts has one implicit job slot reserved
-for it before it starts.  Any tool which wants to participate in the
-jobserver protocol should assume it can always run one job without
-having to contact the jobserver at all.
-
-   Finally, it's critical that tools that participate in the jobserver
-protocol return the exact number of slots they obtained from the
-jobserver back to the jobserver before they exit, even under error
-conditions.  Remember that the implicit job slot should *not* be
-returned to the jobserver!  Returning too few slots means that those
-slots will be lost for the rest of the build process; returning too many
-slots means that extra slots will be available.  The top-level 'make'
-command will print an error message at the end of the build if it
-detects an incorrect number of slots available in the jobserver.
-
-   As an example, suppose you are implementing a linker which provides
-for multithreaded operation.  You would like to enhance the linker so
-that if it is invoked by GNU 'make' it can participate in the jobserver
-protocol to control how many threads are used during link.  First you
-will need to modify the linker to determine if the 'MAKEFLAGS'
-environment variable is set.  Next you will need to parse the value of
-that variable to determine if the jobserver is available, and how to
-access it.  If it is available then you can access it to obtain job
-slots controlling how much parallelism your tool can use.  Once done

-13.1.1 POSIX Jobserver Interaction
-----------------------------------
-
-On POSIX systems the jobserver is implemented as a simple UNIX pipe.
-The pipe will be pre-loaded with one single-character token for each
-available job.  To obtain an extra slot you must read a single character
-from the jobserver pipe; to release a slot you must write a single
-character back into the jobserver pipe.  Note that the read side of the
-jobserver pipe is set to "blocking" mode.
-
-   To access the pipe you must parse the 'MAKEFLAGS' variable and look
-for the argument string '--jobserver-auth=R,W' where 'R' and 'W' are
-non-negative integers representing file descriptors: 'R' is the read
-file descriptor and 'W' is the write file descriptor.
-
-   It's important that when you release the job slot, you write back the
-same character you read from the pipe for that slot.  Don't assume that
-all tokens are the same character; different characters may have
-different meanings to GNU 'make'.  The order is not important, since
-'make' has no idea in what order jobs will complete anyway.
-
-   There are various error conditions you must consider to ensure your
-implementation is robust:
-
-   * Usually you will have a command-line argument controlling the
-     parallel operation of your tool.  Consider whether your tool should
-     detect situations where both the jobserver and the command-line
-     argument are specified, and how it should react.
-
-   * If your tool determines that the '--jobserver-auth' option is
-     available in 'MAKEFLAGS' but that the file descriptors specified
-     are closed, this means that the calling 'make' process did not
-     think that your tool was a recursive 'make' invocation (e.g., the
-     command line was not prefixed with a '+' character).  You should
-     notify your users of this situation.
-
-   * Your tool should also examine the first word of the 'MAKEFLAGS'
-     variable and look for the character 'n'.  If this character is
-     present then 'make' was invoked with the '-n' option and your tool
-     should stop without performing any operations.
-
-   * Your tool should be sure to write back the tokens it read, even
-     under error conditions.  This includes not only errors in your tool
-     but also outside influences such as interrupts ('SIGINT'), etc.
-     You may want to install signal handlers to manage this write-back.

-
-13.1.2 Windows Jobserver Interaction
-------------------------------------
-
-On Windows systems the jobserver is implemented as a named semaphore.
-The semaphore will be set with an initial count equal to the number of
-available slots; to obtain a slot you must wait on the semaphore (with
-or without a timeout).  To release a slot, release the semaphore.
-
-   To access the semaphore you must parse the 'MAKEFLAGS' variable and
-look for the argument string '--jobserver-auth=NAME' where 'NAME' is the
-name of the named semaphore.  Use this name with 'OpenSemaphore' to
-create a handle to the semaphore.
-
-   There are various error conditions you must consider to ensure your
-implementation is robust:
-
-   * Usually you will have a command-line argument controlling the
-     parallel operation of your tool.  Consider whether your tool should
-     detect situations where both the jobserver and the command-line
-     argument are specified, and how it should react.
-
-   * Your tool should be sure to release the semaphore for the tokens it
-     read, even under error conditions.  This includes not only errors
-     in your tool but also outside influences such as interrupts
-     ('SIGINT'), etc.  You may want to install signal handlers to manage
-     this write-back.

-
-13.2 Synchronized Terminal Output
-=================================
-
-Normally GNU 'make' will invoke all commands with access to the same
-standard and error outputs that 'make' itself was started with.  A
-number of tools will detect whether the output is a terminal or
-not-a-terminal, and use this information to change the output style.
-For example if the output goes to a terminal the tool may add control
-characters that set color, or even change the location of the cursor.
-If the output is not going to a terminal then these special control
-characters are not emitted so that they don't corrupt log files, etc.
-
-   The '--output-sync' (*note Output During Parallel Output: Parallel
-Output.) option will defeat the terminal detection.  When output
-synchronization is enabled GNU 'make' arranges for all command output to
-be written to a file, so that its output can be written as a block
-without interference from other commands.  This means that all tools
-invoked by 'make' will believe that their output is not going to be
-displayed on a terminal, even when it will be (because 'make' will
-display it there after the command is completed).
-
-   In order to facilitate tools which would like to determine whether or
-not their output will be displayed on a terminal, GNU 'make' will set
-the 'MAKE_TERMOUT' and 'MAKE_TERMERR' environment variables before
-invoking any commands.  Tools which would like to determine whether
-standard or error output (respectively) will be displayed on a terminal
-can check these environment variables to determine if they exist and
-contain a non-empty value.  If so the tool can assume that the output
-will (eventually) be displayed on a terminal.  If the variables are not
-set or have an empty value, then the tool should fall back to its normal
-methods of detecting whether output is going to a terminal or not.
-
-   The content of the variables can be parsed to determine the type of
-terminal which will be used to display the output.
-
-   Similarly, environments which invoke 'make' and would like to capture
-the output and eventually display it on a terminal (or some display
-which can interpret terminal control characters) can set these variables
-before invoking 'make'.  GNU 'make' will not modify these environment
-variables if they already exist when it starts.

-14 Features of GNU 'make'
-*************************
-
-Here is a summary of the features of GNU 'make', for comparison with and
-credit to other versions of 'make'.  We consider the features of 'make'
-in 4.2 BSD systems as a baseline.  If you are concerned with writing
-portable makefiles, you should not use the features of 'make' listed
-here, nor the ones in *note Missing::.
-
-   Many features come from the version of 'make' in System V.
-
-   * The 'VPATH' variable and its special meaning.  *Note Searching
-     Directories for Prerequisites: Directory Search.  This feature
-     exists in System V 'make', but is undocumented.  It is documented
-     in 4.3 BSD 'make' (which says it mimics System V's 'VPATH'
-     feature).
-
-   * Included makefiles.  *Note Including Other Makefiles: Include.
-     Allowing multiple files to be included with a single directive is a
-     GNU extension.
-
-   * Variables are read from and communicated via the environment.
-     *Note Variables from the Environment: Environment.
-
-   * Options passed through the variable 'MAKEFLAGS' to recursive
-     invocations of 'make'.  *Note Communicating Options to a
-     Sub-'make': Options/Recursion.
-
-   * The automatic variable '$%' is set to the member name in an archive
-     reference.  *Note Automatic Variables::.
-
-   * The automatic variables '$@', '$*', '$<', '$%', and '$?' have
-     corresponding forms like '$(@F)' and '$(@D)'.  We have generalized
-     this to '$^' as an obvious extension.  *Note Automatic Variables::.
-
-   * Substitution variable references.  *Note Basics of Variable
-     References: Reference.
-
-   * The command line options '-b' and '-m', accepted and ignored.  In
-     System V 'make', these options actually do something.
-
-   * Execution of recursive commands to run 'make' via the variable
-     'MAKE' even if '-n', '-q' or '-t' is specified.  *Note Recursive
-     Use of 'make': Recursion.
-
-   * Support for suffix '.a' in suffix rules.  *Note Archive Suffix
-     Rules::.  This feature is obsolete in GNU 'make', because the
-     general feature of rule chaining (*note Chains of Implicit Rules:
-     Chained Rules.) allows one pattern rule for installing members in
-     an archive (*note Archive Update::) to be sufficient.
-
-   * The arrangement of lines and backslash/newline combinations in
-     recipes is retained when the recipes are printed, so they appear as
-     they do in the makefile, except for the stripping of initial
-     whitespace.
-
-   The following features were inspired by various other versions of
-'make'.  In some cases it is unclear exactly which versions inspired
-which others.
-
-   * Pattern rules using '%'.  This has been implemented in several
-     versions of 'make'.  We're not sure who invented it first, but it's
-     been spread around a bit.  *Note Defining and Redefining Pattern
-     Rules: Pattern Rules.
-
-   * Rule chaining and implicit intermediate files.  This was
-     implemented by Stu Feldman in his version of 'make' for AT&T Eighth
-     Edition Research Unix, and later by Andrew Hume of AT&T Bell Labs
-     in his 'mk' program (where he terms it "transitive closure").  We
-     do not really know if we got this from either of them or thought it
-     up ourselves at the same time.  *Note Chains of Implicit Rules:
-     Chained Rules.
-
-   * The automatic variable '$^' containing a list of all prerequisites
-     of the current target.  We did not invent this, but we have no idea
-     who did.  *Note Automatic Variables::.  The automatic variable '$+'
-     is a simple extension of '$^'.
-
-   * The "what if" flag ('-W' in GNU 'make') was (as far as we know)
-     invented by Andrew Hume in 'mk'.  *Note Instead of Executing
-     Recipes: Instead of Execution.
-
-   * The concept of doing several things at once (parallelism) exists in
-     many incarnations of 'make' and similar programs, though not in the
-     System V or BSD implementations.  *Note Recipe Execution:
-     Execution.
-
-   * A number of different build tools that support parallelism also
-     support collecting output and displaying as a single block.  *Note
-     Output During Parallel Execution: Parallel Output.
-
-   * Modified variable references using pattern substitution come from
-     SunOS 4.  *Note Basics of Variable References: Reference.  This
-     functionality was provided in GNU 'make' by the 'patsubst' function
-     before the alternate syntax was implemented for compatibility with
-     SunOS 4.  It is not altogether clear who inspired whom, since GNU
-     'make' had 'patsubst' before SunOS 4 was released.
-
-   * The special significance of '+' characters preceding recipe lines
-     (*note Instead of Executing Recipes: Instead of Execution.) is
-     mandated by 'IEEE Standard 1003.2-1992' (POSIX.2).
-
-   * The '+=' syntax to append to the value of a variable comes from
-     SunOS 4 'make'.  *Note Appending More Text to Variables: Appending.
-
-   * The syntax 'ARCHIVE(MEM1 MEM2...)' to list multiple members in a
-     single archive file comes from SunOS 4 'make'.  *Note Archive
-     Members::.
-
-   * The '-include' directive to include makefiles with no error for a
-     nonexistent file comes from SunOS 4 'make'.  (But note that SunOS 4
-     'make' does not allow multiple makefiles to be specified in one
-     '-include' directive.)  The same feature appears with the name
-     'sinclude' in SGI 'make' and perhaps others.
-
-   * The '!=' shell assignment operator exists in many BSD of 'make' and
-     is purposefully implemented here to behave identically to those
-     implementations.
-
-   * Various build management tools are implemented using scripting
-     languages such as Perl or Python and thus provide a natural
-     embedded scripting language, similar to GNU 'make''s integration of
-     GNU Guile.
-
-   The remaining features are inventions new in GNU 'make':
-
-   * Use the '-v' or '--version' option to print version and copyright
-     information.
-
-   * Use the '-h' or '--help' option to summarize the options to 'make'.
-
-   * Simply-expanded variables.  *Note The Two Flavors of Variables:
-     Flavors.
-
-   * Pass command line variable assignments automatically through the
-     variable 'MAKE' to recursive 'make' invocations.  *Note Recursive
-     Use of 'make': Recursion.
-
-   * Use the '-C' or '--directory' command option to change directory.
-     *Note Summary of Options: Options Summary.
-
-   * Make verbatim variable definitions with 'define'.  *Note Defining
-     Multi-Line Variables: Multi-Line.
-
-   * Declare phony targets with the special target '.PHONY'.
-
-     Andrew Hume of AT&T Bell Labs implemented a similar feature with a
-     different syntax in his 'mk' program.  This seems to be a case of
-     parallel discovery.  *Note Phony Targets: Phony Targets.
-
-   * Manipulate text by calling functions.  *Note Functions for
-     Transforming Text: Functions.
-
-   * Use the '-o' or '--old-file' option to pretend a file's
-     modification-time is old.  *Note Avoiding Recompilation of Some
-     Files: Avoiding Compilation.
-
-   * Conditional execution.
-
-     This feature has been implemented numerous times in various
-     versions of 'make'; it seems a natural extension derived from the
-     features of the C preprocessor and similar macro languages and is
-     not a revolutionary concept.  *Note Conditional Parts of Makefiles:
-     Conditionals.
-
-   * Specify a search path for included makefiles.  *Note Including
-     Other Makefiles: Include.
-
-   * Specify extra makefiles to read with an environment variable.
-     *Note The Variable 'MAKEFILES': MAKEFILES Variable.
-
-   * Strip leading sequences of './' from file names, so that './FILE'
-     and 'FILE' are considered to be the same file.
-
-   * Use a special search method for library prerequisites written in
-     the form '-lNAME'.  *Note Directory Search for Link Libraries:
-     Libraries/Search.
-
-   * Allow suffixes for suffix rules (*note Old-Fashioned Suffix Rules:
-     Suffix Rules.) to contain any characters.  In other versions of
-     'make', they must begin with '.' and not contain any '/'
-     characters.
-
-   * Keep track of the current level of 'make' recursion using the
-     variable 'MAKELEVEL'.  *Note Recursive Use of 'make': Recursion.
-
-   * Provide any goals given on the command line in the variable
-     'MAKECMDGOALS'.  *Note Arguments to Specify the Goals: Goals.
-
-   * Specify static pattern rules.  *Note Static Pattern Rules: Static
-     Pattern.
-
-   * Provide selective 'vpath' search.  *Note Searching Directories for
-     Prerequisites: Directory Search.
-

-
-   * Update makefiles.  *Note How Makefiles Are Remade: Remaking

-15 Incompatibilities and Missing Features
-*****************************************
-
-The 'make' programs in various other systems support a few features that
-are not implemented in GNU 'make'.  The POSIX.2 standard ('IEEE Standard
-1003.2-1992') which specifies 'make' does not require any of these
-features.
-
-   * A target of the form 'FILE((ENTRY))' stands for a member of archive
-     file FILE.  The member is chosen, not by name, but by being an
-     object file which defines the linker symbol ENTRY.
-
-     This feature was not put into GNU 'make' because of the
-     non-modularity of putting knowledge into 'make' of the internal
-     format of archive file symbol tables.  *Note Updating Archive
-     Symbol Directories: Archive Symbols.
-
-   * Suffixes (used in suffix rules) that end with the character '~'
-     have a special meaning to System V 'make'; they refer to the SCCS
-     file that corresponds to the file one would get without the '~'.
-     For example, the suffix rule '.c~.o' would make the file 'N.o' from
-     the SCCS file 's.N.c'.  For complete coverage, a whole series of
-     such suffix rules is required.  *Note Old-Fashioned Suffix Rules:
-     Suffix Rules.
-
-     In GNU 'make', this entire series of cases is handled by two
-     pattern rules for extraction from SCCS, in combination with the
-     general feature of rule chaining.  *Note Chains of Implicit Rules:
-     Chained Rules.
-
-   * In System V and 4.3 BSD 'make', files found by 'VPATH' search
-     (*note Searching Directories for Prerequisites: Directory Search.)
-     have their names changed inside recipes.  We feel it is much
-     cleaner to always use automatic variables and thus make this
-     feature unnecessary.
-
-   * In some Unix 'make's, the automatic variable '$*' appearing in the
-     prerequisites of a rule has the amazingly strange "feature" of
-     expanding to the full name of the _target of that rule_.  We cannot
-     imagine what went on in the minds of Unix 'make' developers to do
-     this; it is utterly inconsistent with the normal definition of
-     '$*'.
-
-   * In some Unix 'make's, implicit rule search (*note Using Implicit
-     Rules: Implicit Rules.) is apparently done for _all_ targets, not
-     just those without recipes.  This means you can do:
-
-          foo.o:
-                  cc -c foo.c
-
-     and Unix 'make' will intuit that 'foo.o' depends on 'foo.c'.
-
-     We feel that such usage is broken.  The prerequisite properties of
-     'make' are well-defined (for GNU 'make', at least), and doing such
-     a thing simply does not fit the model.
-
-   * GNU 'make' does not include any built-in implicit rules for
-     compiling or preprocessing EFL programs.  If we hear of anyone who
-     is using EFL, we will gladly add them.
-
-   * It appears that in SVR4 'make', a suffix rule can be specified with
-     no recipe, and it is treated as if it had an empty recipe (*note
-     Empty Recipes::).  For example:
-
-          .c.a:
-
-     will override the built-in '.c.a' suffix rule.
-
-     We feel that it is cleaner for a rule without a recipe to always
-     simply add to the prerequisite list for the target.  The above
-     example can be easily rewritten to get the desired behavior in GNU
-     'make':
-
-          .c.a: ;
-
-   * Some versions of 'make' invoke the shell with the '-e' flag, except
-     under '-k' (*note Testing the Compilation of a Program: Testing.).
-     The '-e' flag tells the shell to exit as soon as any program it
-     runs returns a nonzero status.  We feel it is cleaner to write each
-     line of the recipe to stand on its own and not require this special
-     treatment.

-
-16.1 General Conventions for Makefiles
-======================================
-
-Every Makefile should contain this line:
-
-     SHELL = /bin/sh
-
-to avoid trouble on systems where the 'SHELL' variable might be
-inherited from the environment.  (This is never a problem with GNU
-'make'.)
-
-   Different 'make' programs have incompatible suffix lists and implicit
-rules, and this sometimes creates confusion or misbehavior.  So it is a
-good idea to set the suffix list explicitly using only the suffixes you
-need in the particular Makefile, like this:
-
-     .SUFFIXES:
-     .SUFFIXES: .c .o
-
-The first line clears out the suffix list, the second introduces all
-suffixes which may be subject to implicit rules in this Makefile.
-
-   Don't assume that '.' is in the path for command execution.  When you
-need to run programs that are a part of your package during the make,
-please make sure that it uses './' if the program is built as part of
-the make or '$(srcdir)/' if the file is an unchanging part of the source
-code.  Without one of these prefixes, the current search path is used.
-
-   The distinction between './' (the "build directory") and '$(srcdir)/'
-(the "source directory") is important because users can build in a
-separate directory using the '--srcdir' option to 'configure'.  A rule
-of the form:
-
-     foo.1 : foo.man sedscript
-             sed -f sedscript foo.man > foo.1
-
-will fail when the build directory is not the source directory, because
-'foo.man' and 'sedscript' are in the source directory.
-
-   When using GNU 'make', relying on 'VPATH' to find the source file
-will work in the case where there is a single dependency file, since the
-'make' automatic variable '$<' will represent the source file wherever
-it is.  (Many versions of 'make' set '$<' only in implicit rules.)  A
-Makefile target like
-
-     foo.o : bar.c
-             $(CC) -I. -I$(srcdir) $(CFLAGS) -c bar.c -o foo.o
-
-should instead be written as
-
-     foo.o : bar.c
-             $(CC) -I. -I$(srcdir) $(CFLAGS) -c $< -o $@
-
-in order to allow 'VPATH' to work correctly.  When the target has
-multiple dependencies, using an explicit '$(srcdir)' is the easiest way
-to make the rule work well.  For example, the target above for 'foo.1'
-is best written as:
-
-     foo.1 : foo.man sedscript
-             sed -f $(srcdir)/sedscript $(srcdir)/foo.man > $@
-
-   GNU distributions usually contain some files which are not source
-files--for example, Info files, and the output from Autoconf, Automake,
-Bison or Flex.  Since these files normally appear in the source
-directory, they should always appear in the source directory, not in the
-build directory.  So Makefile rules to update them should put the
-updated files in the source directory.
-
-   However, if a file does not appear in the distribution, then the
-Makefile should not put it in the source directory, because building a
-program in ordinary circumstances should not modify the source directory
-in any way.
-
-   Try to make the build and installation targets, at least (and all
-their subtargets) work correctly with a parallel 'make'.

-
-16.2 Utilities in Makefiles
-===========================
-
-Write the Makefile commands (and any shell scripts, such as 'configure')
-to run under 'sh' (both the traditional Bourne shell and the POSIX
-shell), not 'csh'.  Don't use any special features of 'ksh' or 'bash',
-or POSIX features not widely supported in traditional Bourne 'sh'.
-
-   The 'configure' script and the Makefile rules for building and
-installation should not use any utilities directly except these:
-
-     awk cat cmp cp diff echo egrep expr false grep install-info ln ls
-     mkdir mv printf pwd rm rmdir sed sleep sort tar test touch tr true
-
-   Compression programs such as 'gzip' can be used in the 'dist' rule.
-
-   Generally, stick to the widely-supported (usually POSIX-specified)
-options and features of these programs.  For example, don't use 'mkdir
--p', convenient as it may be, because a few systems don't support it at
-all and with others, it is not safe for parallel execution.  For a list
-of known incompatibilities, see *note Portable Shell Programming:
-(autoconf)Portable Shell.
-
-   It is a good idea to avoid creating symbolic links in makefiles,
-since a few file systems don't support them.
-
-   The Makefile rules for building and installation can also use
-compilers and related programs, but should do so via 'make' variables so
-that the user can substitute alternatives.  Here are some of the
-programs we mean:
-
-     ar bison cc flex install ld ldconfig lex
-     make makeinfo ranlib texi2dvi yacc
-
-   Use the following 'make' variables to run those programs:
-
-     $(AR) $(BISON) $(CC) $(FLEX) $(INSTALL) $(LD) $(LDCONFIG) $(LEX)
-     $(MAKE) $(MAKEINFO) $(RANLIB) $(TEXI2DVI) $(YACC)
-
-   When you use 'ranlib' or 'ldconfig', you should make sure nothing bad
-happens if the system does not have the program in question.  Arrange to
-ignore an error from that command, and print a message before the
-command to tell the user that failure of this command does not mean a
-problem.  (The Autoconf 'AC_PROG_RANLIB' macro can help with this.)
-
-   If you use symbolic links, you should implement a fallback for
-systems that don't have symbolic links.
-
-   Additional utilities that can be used via Make variables are:
-
-     chgrp chmod chown mknod
-
-   It is ok to use other utilities in Makefile portions (or scripts)
-intended only for particular systems where you know those utilities
-exist.

-16.3 Variables for Specifying Commands
-======================================
-
-Makefiles should provide variables for overriding certain commands,
-options, and so on.
-
-   In particular, you should run most utility programs via variables.
-Thus, if you use Bison, have a variable named 'BISON' whose default
-value is set with 'BISON = bison', and refer to it with '$(BISON)'
-whenever you need to use Bison.
-
-   File management utilities such as 'ln', 'rm', 'mv', and so on, need
-not be referred to through variables in this way, since users don't need
-to replace them with other programs.
-
-   Each program-name variable should come with an options variable that
-is used to supply options to the program.  Append 'FLAGS' to the
-program-name variable name to get the options variable name--for
-example, 'BISONFLAGS'.  (The names 'CFLAGS' for the C compiler, 'YFLAGS'
-for yacc, and 'LFLAGS' for lex, are exceptions to this rule, but we keep
-them because they are standard.)  Use 'CPPFLAGS' in any compilation
-command that runs the preprocessor, and use 'LDFLAGS' in any compilation
-command that does linking as well as in any direct use of 'ld'.
-
-   If there are C compiler options that _must_ be used for proper
-compilation of certain files, do not include them in 'CFLAGS'.  Users
-expect to be able to specify 'CFLAGS' freely themselves.  Instead,
-arrange to pass the necessary options to the C compiler independently of
-'CFLAGS', by writing them explicitly in the compilation commands or by
-defining an implicit rule, like this:
-
-     CFLAGS = -g
-     ALL_CFLAGS = -I. $(CFLAGS)
-     .c.o:
-             $(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $<
-
-   Do include the '-g' option in 'CFLAGS', because that is not
-_required_ for proper compilation.  You can consider it a default that
-is only recommended.  If the package is set up so that it is compiled
-with GCC by default, then you might as well include '-O' in the default
-value of 'CFLAGS' as well.
-
-   Put 'CFLAGS' last in the compilation command, after other variables
-containing compiler options, so the user can use 'CFLAGS' to override
-the others.
-
-   'CFLAGS' should be used in every invocation of the C compiler, both
-those which do compilation and those which do linking.
-
-   Every Makefile should define the variable 'INSTALL', which is the
-basic command for installing a file into the system.
-
-   Every Makefile should also define the variables 'INSTALL_PROGRAM' and
-'INSTALL_DATA'.  (The default for 'INSTALL_PROGRAM' should be
-'$(INSTALL)'; the default for 'INSTALL_DATA' should be '${INSTALL} -m
-644'.)  Then it should use those variables as the commands for actual
-installation, for executables and non-executables respectively.  Minimal
-use of these variables is as follows:
-
-     $(INSTALL_PROGRAM) foo $(bindir)/foo
-     $(INSTALL_DATA) libfoo.a $(libdir)/libfoo.a
-
-   However, it is preferable to support a 'DESTDIR' prefix on the target
-files, as explained in the next section.
-
-   It is acceptable, but not required, to install multiple files in one
-command, with the final argument being a directory, as in:
-
-     $(INSTALL_PROGRAM) foo bar baz $(bindir)
-
-
-File: make.info,  Node: DESTDIR,  Next: Directory Variables,  Prev: Command Variables,  Up: Makefile Conventions
-
-16.4 'DESTDIR': Support for Staged Installs
-===========================================
-
-'DESTDIR' is a variable prepended to each installed target file, like
-this:
-
-     $(INSTALL_PROGRAM) foo $(DESTDIR)$(bindir)/foo
-     $(INSTALL_DATA) libfoo.a $(DESTDIR)$(libdir)/libfoo.a
-
-   The 'DESTDIR' variable is specified by the user on the 'make' command
-line as an absolute file name.  For example:
-
-     make DESTDIR=/tmp/stage install
-
-'DESTDIR' should be supported only in the 'install*' and 'uninstall*'
-targets, as those are the only targets where it is useful.
-
-   If your installation step would normally install '/usr/local/bin/foo'
-and '/usr/local/lib/libfoo.a', then an installation invoked as in the
-example above would install '/tmp/stage/usr/local/bin/foo' and
-'/tmp/stage/usr/local/lib/libfoo.a' instead.
-
-   Prepending the variable 'DESTDIR' to each target in this way provides
-for "staged installs", where the installed files are not placed directly
-into their expected location but are instead copied into a temporary
-location ('DESTDIR').  However, installed files maintain their relative
-directory structure and any embedded file names will not be modified.
-
-   You should not set the value of 'DESTDIR' in your 'Makefile' at all;
-then the files are installed into their expected locations by default.
-Also, specifying 'DESTDIR' should not change the operation of the
-software in any way, so its value should not be included in any file
-contents.
-
-   'DESTDIR' support is commonly used in package creation.  It is also
-helpful to users who want to understand what a given package will
-install where, and to allow users who don't normally have permissions to
-install into protected areas to build and install before gaining those
-permissions.  Finally, it can be useful with tools such as 'stow', where
-code is installed in one place but made to appear to be installed
-somewhere else using symbolic links or special mount operations.  So, we
-strongly recommend GNU packages support 'DESTDIR', though it is not an
-absolute requirement.

-16.5 Variables for Installation Directories
-===========================================
-
-Installation directories should always be named by variables, so it is
-easy to install in a nonstandard place.  The standard names for these
-variables and the values they should have in GNU packages are described
-below.  They are based on a standard file system layout; variants of it
-are used in GNU/Linux and other modern operating systems.
-
-   Installers are expected to override these values when calling 'make'
-(e.g., 'make prefix=/usr install') or 'configure' (e.g., 'configure
---prefix=/usr').  GNU packages should not try to guess which value
-should be appropriate for these variables on the system they are being
-installed onto: use the default settings specified here so that all GNU
-packages behave identically, allowing the installer to achieve any
-desired layout.
-
-   All installation directories, and their parent directories, should be
-created (if necessary) before they are installed into.
-
-   These first two variables set the root for the installation.  All the
-other installation directories should be subdirectories of one of these
-two, and nothing should be directly installed into these two
-directories.
-
-'prefix'
-     A prefix used in constructing the default values of the variables
-     listed below.  The default value of 'prefix' should be
-     '/usr/local'.  When building the complete GNU system, the prefix
-     will be empty and '/usr' will be a symbolic link to '/'.  (If you
-     are using Autoconf, write it as '@prefix@'.)
-
-     Running 'make install' with a different value of 'prefix' from the
-     one used to build the program should _not_ recompile the program.
-
-'exec_prefix'
-     A prefix used in constructing the default values of some of the
-     variables listed below.  The default value of 'exec_prefix' should
-     be '$(prefix)'.  (If you are using Autoconf, write it as
-     '@exec_prefix@'.)
-
-     Generally, '$(exec_prefix)' is used for directories that contain
-     machine-specific files (such as executables and subroutine
-     libraries), while '$(prefix)' is used directly for other
-     directories.
-
-     Running 'make install' with a different value of 'exec_prefix' from
-     the one used to build the program should _not_ recompile the
-     program.
-
-   Executable programs are installed in one of the following
-directories.
-
-'bindir'
-     The directory for installing executable programs that users can
-     run.  This should normally be '/usr/local/bin', but write it as
-     '$(exec_prefix)/bin'.  (If you are using Autoconf, write it as
-     '@bindir@'.)
-
-'sbindir'
-     The directory for installing executable programs that can be run
-     from the shell, but are only generally useful to system
-     administrators.  This should normally be '/usr/local/sbin', but
-     write it as '$(exec_prefix)/sbin'.  (If you are using Autoconf,
-     write it as '@sbindir@'.)
-
-'libexecdir'
-     The directory for installing executable programs to be run by other
-     programs rather than by users.  This directory should normally be
-     '/usr/local/libexec', but write it as '$(exec_prefix)/libexec'.
-     (If you are using Autoconf, write it as '@libexecdir@'.)
-
-     The definition of 'libexecdir' is the same for all packages, so you
-     should install your data in a subdirectory thereof.  Most packages
-     install their data under '$(libexecdir)/PACKAGE-NAME/', possibly
-     within additional subdirectories thereof, such as
-     '$(libexecdir)/PACKAGE-NAME/MACHINE/VERSION'.
-
-   Data files used by the program during its execution are divided into
-categories in two ways.
-
-   * Some files are normally modified by programs; others are never
-     normally modified (though users may edit some of these).
-
-   * Some files are architecture-independent and can be shared by all
-     machines at a site; some are architecture-dependent and can be
-     shared only by machines of the same kind and operating system;
-     others may never be shared between two machines.
-
-   This makes for six different possibilities.  However, we want to
-discourage the use of architecture-dependent files, aside from object
-files and libraries.  It is much cleaner to make other data files
-architecture-independent, and it is generally not hard.
-
-   Here are the variables Makefiles should use to specify directories to
-put these various kinds of files in:
-
-'datarootdir'
-     The root of the directory tree for read-only
-     architecture-independent data files.  This should normally be
-     '/usr/local/share', but write it as '$(prefix)/share'.  (If you are
-     using Autoconf, write it as '@datarootdir@'.)  'datadir''s default
-     value is based on this variable; so are 'infodir', 'mandir', and
-     others.
-
-'datadir'
-     The directory for installing idiosyncratic read-only
-     architecture-independent data files for this program.  This is
-     usually the same place as 'datarootdir', but we use the two
-     separate variables so that you can move these program-specific
-     files without altering the location for Info files, man pages, etc.
-
-     This should normally be '/usr/local/share', but write it as
-     '$(datarootdir)'.  (If you are using Autoconf, write it as
-     '@datadir@'.)
-
-     The definition of 'datadir' is the same for all packages, so you
-     should install your data in a subdirectory thereof.  Most packages
-     install their data under '$(datadir)/PACKAGE-NAME/'.
-
-'sysconfdir'
-     The directory for installing read-only data files that pertain to a
-     single machine-that is to say, files for configuring a host.
-     Mailer and network configuration files, '/etc/passwd', and so forth
-     belong here.  All the files in this directory should be ordinary
-     ASCII text files.  This directory should normally be
-     '/usr/local/etc', but write it as '$(prefix)/etc'.  (If you are
-     using Autoconf, write it as '@sysconfdir@'.)
-
-     Do not install executables here in this directory (they probably
-     belong in '$(libexecdir)' or '$(sbindir)').  Also do not install
-     files that are modified in the normal course of their use (programs
-     whose purpose is to change the configuration of the system
-     excluded).  Those probably belong in '$(localstatedir)'.
-
-'sharedstatedir'
-     The directory for installing architecture-independent data files
-     which the programs modify while they run.  This should normally be
-     '/usr/local/com', but write it as '$(prefix)/com'.  (If you are
-     using Autoconf, write it as '@sharedstatedir@'.)
-
-'localstatedir'
-     The directory for installing data files which the programs modify
-     while they run, and that pertain to one specific machine.  Users
-     should never need to modify files in this directory to configure
-     the package's operation; put such configuration information in
-     separate files that go in '$(datadir)' or '$(sysconfdir)'.
-     '$(localstatedir)' should normally be '/usr/local/var', but write
-     it as '$(prefix)/var'.  (If you are using Autoconf, write it as
-     '@localstatedir@'.)
-
-'runstatedir'
-     The directory for installing data files which the programs modify
-     while they run, that pertain to one specific machine, and which
-     need not persist longer than the execution of the program--which is
-     generally long-lived, for example, until the next reboot.  PID
-     files for system daemons are a typical use.  In addition, this
-     directory should not be cleaned except perhaps at reboot, while the
-     general '/tmp' ('TMPDIR') may be cleaned arbitrarily.  This should
-     normally be '/var/run', but write it as '$(localstatedir)/run'.
-     Having it as a separate variable allows the use of '/run' if
-     desired, for example.  (If you are using Autoconf 2.70 or later,
-     write it as '@runstatedir@'.)
-
-   These variables specify the directory for installing certain specific
-types of files, if your program has them.  Every GNU package should have
-Info files, so every program needs 'infodir', but not all need 'libdir'
-or 'lispdir'.
-
-'includedir'
-     The directory for installing header files to be included by user
-     programs with the C '#include' preprocessor directive.  This should
-     normally be '/usr/local/include', but write it as
-     '$(prefix)/include'.  (If you are using Autoconf, write it as
-     '@includedir@'.)
-
-     Most compilers other than GCC do not look for header files in
-     directory '/usr/local/include'.  So installing the header files
-     this way is only useful with GCC. Sometimes this is not a problem
-     because some libraries are only really intended to work with GCC.
-     But some libraries are intended to work with other compilers.  They
-     should install their header files in two places, one specified by
-     'includedir' and one specified by 'oldincludedir'.
-
-'oldincludedir'
-     The directory for installing '#include' header files for use with
-     compilers other than GCC. This should normally be '/usr/include'.
-     (If you are using Autoconf, you can write it as '@oldincludedir@'.)
-
-     The Makefile commands should check whether the value of
-     'oldincludedir' is empty.  If it is, they should not try to use it;
-     they should cancel the second installation of the header files.
-
-     A package should not replace an existing header in this directory
-     unless the header came from the same package.  Thus, if your Foo
-     package provides a header file 'foo.h', then it should install the
-     header file in the 'oldincludedir' directory if either (1) there is
-     no 'foo.h' there or (2) the 'foo.h' that exists came from the Foo
-     package.
-
-     To tell whether 'foo.h' came from the Foo package, put a magic
-     string in the file--part of a comment--and 'grep' for that string.
-
-'docdir'
-     The directory for installing documentation files (other than Info)
-     for this package.  By default, it should be
-     '/usr/local/share/doc/YOURPKG', but it should be written as
-     '$(datarootdir)/doc/YOURPKG'.  (If you are using Autoconf, write it
-     as '@docdir@'.)  The YOURPKG subdirectory, which may include a
-     version number, prevents collisions among files with common names,
-     such as 'README'.
-
-'infodir'
-     The directory for installing the Info files for this package.  By
-     default, it should be '/usr/local/share/info', but it should be
-     written as '$(datarootdir)/info'.  (If you are using Autoconf,
-     write it as '@infodir@'.)  'infodir' is separate from 'docdir' for
-     compatibility with existing practice.
-
-'htmldir'
-'dvidir'
-'pdfdir'
-'psdir'
-     Directories for installing documentation files in the particular
-     format.  They should all be set to '$(docdir)' by default.  (If you
-     are using Autoconf, write them as '@htmldir@', '@dvidir@', etc.)
-     Packages which supply several translations of their documentation
-     should install them in '$(htmldir)/'LL, '$(pdfdir)/'LL, etc.  where
-     LL is a locale abbreviation such as 'en' or 'pt_BR'.
-
-'libdir'
-     The directory for object files and libraries of object code.  Do
-     not install executables here, they probably ought to go in
-     '$(libexecdir)' instead.  The value of 'libdir' should normally be
-     '/usr/local/lib', but write it as '$(exec_prefix)/lib'.  (If you
-     are using Autoconf, write it as '@libdir@'.)
-
-'lispdir'
-     The directory for installing any Emacs Lisp files in this package.
-     By default, it should be '/usr/local/share/emacs/site-lisp', but it
-     should be written as '$(datarootdir)/emacs/site-lisp'.
-
-     If you are using Autoconf, write the default as '@lispdir@'.  In
-     order to make '@lispdir@' work, you need the following lines in
-     your 'configure.ac' file:
-
-          lispdir='${datarootdir}/emacs/site-lisp'
-          AC_SUBST(lispdir)
-
-'localedir'
-     The directory for installing locale-specific message catalogs for
-     this package.  By default, it should be '/usr/local/share/locale',
-     but it should be written as '$(datarootdir)/locale'.  (If you are
-     using Autoconf, write it as '@localedir@'.)  This directory usually
-     has a subdirectory per locale.
-
-   Unix-style man pages are installed in one of the following:
-
-'mandir'
-     The top-level directory for installing the man pages (if any) for
-     this package.  It will normally be '/usr/local/share/man', but you
-     should write it as '$(datarootdir)/man'.  (If you are using
-     Autoconf, write it as '@mandir@'.)
-
-'man1dir'
-     The directory for installing section 1 man pages.  Write it as
-     '$(mandir)/man1'.
-'man2dir'
-     The directory for installing section 2 man pages.  Write it as
-     '$(mandir)/man2'
-'...'
-
-     *Don't make the primary documentation for any GNU software be a man
-     page.  Write a manual in Texinfo instead.  Man pages are just for
-     the sake of people running GNU software on Unix, which is a
-     secondary application only.*
-
-'manext'
-     The file name extension for the installed man page.  This should
-     contain a period followed by the appropriate digit; it should
-     normally be '.1'.
-
-'man1ext'
-     The file name extension for installed section 1 man pages.
-'man2ext'
-     The file name extension for installed section 2 man pages.
-'...'
-     Use these names instead of 'manext' if the package needs to install
-     man pages in more than one section of the manual.
-
-   And finally, you should set the following variable:
-
-'srcdir'
-     The directory for the sources being compiled.  The value of this
-     variable is normally inserted by the 'configure' shell script.  (If
-     you are using Autoconf, use 'srcdir = @srcdir@'.)
-
-   For example:
-
-     # Common prefix for installation directories.
-     # NOTE: This directory must exist when you start the install.
-     prefix = /usr/local
-     datarootdir = $(prefix)/share
-     datadir = $(datarootdir)
-     exec_prefix = $(prefix)
-     # Where to put the executable for the command 'gcc'.
-     bindir = $(exec_prefix)/bin
-     # Where to put the directories used by the compiler.
-     libexecdir = $(exec_prefix)/libexec
-     # Where to put the Info files.
-     infodir = $(datarootdir)/info
-
-   If your program installs a large number of files into one of the
-standard user-specified directories, it might be useful to group them
-into a subdirectory particular to that program.  If you do this, you
-should write the 'install' rule to create these subdirectories.
-
-   Do not expect the user to include the subdirectory name in the value
-of any of the variables listed above.  The idea of having a uniform set
-of variable names for installation directories is to enable the user to
-specify the exact same values for several different GNU packages.  In
-order for this to be useful, all the packages must be designed so that
-they will work sensibly when the user does so.
-
-   At times, not all of these variables may be implemented in the
-current release of Autoconf and/or Automake; but as of Autoconf 2.60, we
-believe all of them are.  When any are missing, the descriptions here
-serve as specifications for what Autoconf will implement.  As a
-programmer, you can either use a development version of Autoconf or
-avoid using these variables until a stable release is made which
-supports them.

-
-16.6 Standard Targets for Users
-===============================
-
-All GNU programs should have the following targets in their Makefiles:
-
-'all'
-     Compile the entire program.  This should be the default target.
-     This target need not rebuild any documentation files; Info files
-     should normally be included in the distribution, and DVI (and other
-     documentation format) files should be made only when explicitly
-     asked for.
-
-     By default, the Make rules should compile and link with '-g', so
-     that executable programs have debugging symbols.  Otherwise, you
-     are essentially helpless in the face of a crash, and it is often
-     far from easy to reproduce with a fresh build.
-
-'install'
-     Compile the program and copy the executables, libraries, and so on
-     to the file names where they should reside for actual use.  If
-     there is a simple test to verify that a program is properly
-     installed, this target should run that test.
-
-     Do not strip executables when installing them.  This helps eventual
-     debugging that may be needed later, and nowadays disk space is
-     cheap and dynamic loaders typically ensure debug sections are not
-     loaded during normal execution.  Users that need stripped binaries
-     may invoke the 'install-strip' target to do that.
-
-     If possible, write the 'install' target rule so that it does not
-     modify anything in the directory where the program was built,
-     provided 'make all' has just been done.  This is convenient for
-     building the program under one user name and installing it under
-     another.
-
-     The commands should create all the directories in which files are
-     to be installed, if they don't already exist.  This includes the
-     directories specified as the values of the variables 'prefix' and
-     'exec_prefix', as well as all subdirectories that are needed.  One
-     way to do this is by means of an 'installdirs' target as described
-     below.
-
-     Use '-' before any command for installing a man page, so that
-     'make' will ignore any errors.  This is in case there are systems
-     that don't have the Unix man page documentation system installed.
-
-     The way to install Info files is to copy them into '$(infodir)'
-     with '$(INSTALL_DATA)' (*note Command Variables::), and then run
-     the 'install-info' program if it is present.  'install-info' is a
-     program that edits the Info 'dir' file to add or update the menu
-     entry for the given Info file; it is part of the Texinfo package.
-
-     Here is a sample rule to install an Info file that also tries to
-     handle some additional situations, such as 'install-info' not being
-     present.
-
-          do-install-info: foo.info installdirs
-                  $(NORMAL_INSTALL)
-          # Prefer an info file in . to one in srcdir.
-                  if test -f foo.info; then d=.; \
-                   else d="$(srcdir)"; fi; \
-                  $(INSTALL_DATA) $$d/foo.info \
-                    "$(DESTDIR)$(infodir)/foo.info"
-          # Run install-info only if it exists.
-          # Use 'if' instead of just prepending '-' to the
-          # line so we notice real errors from install-info.
-          # Use '$(SHELL) -c' because some shells do not
-          # fail gracefully when there is an unknown command.
-                  $(POST_INSTALL)
-                  if $(SHELL) -c 'install-info --version' \
-                     >/dev/null 2>&1; then \
-                    install-info --dir-file="$(DESTDIR)$(infodir)/dir" \
-                                 "$(DESTDIR)$(infodir)/foo.info"; \
-                  else true; fi
-
-     When writing the 'install' target, you must classify all the
-     commands into three categories: normal ones, "pre-installation"
-     commands and "post-installation" commands.  *Note Install Command
-     Categories::.
-
-'install-html'
-'install-dvi'
-'install-pdf'
-'install-ps'
-     These targets install documentation in formats other than Info;
-     they're intended to be called explicitly by the person installing
-     the package, if that format is desired.  GNU prefers Info files, so
-     these must be installed by the 'install' target.
-
-     When you have many documentation files to install, we recommend
-     that you avoid collisions and clutter by arranging for these
-     targets to install in subdirectories of the appropriate
-     installation directory, such as 'htmldir'.  As one example, if your
-     package has multiple manuals, and you wish to install HTML
-     documentation with many files (such as the "split" mode output by
-     'makeinfo --html'), you'll certainly want to use subdirectories, or
-     two nodes with the same name in different manuals will overwrite
-     each other.
-
-     Please make these 'install-FORMAT' targets invoke the commands for
-     the FORMAT target, for example, by making FORMAT a dependency.
-
-'uninstall'
-     Delete all the installed files--the copies that the 'install' and
-     'install-*' targets create.
-
-     This rule should not modify the directories where compilation is
-     done, only the directories where files are installed.
-
-     The uninstallation commands are divided into three categories, just
-     like the installation commands.  *Note Install Command
-     Categories::.
-
-'install-strip'
-     Like 'install', but strip the executable files while installing
-     them.  In simple cases, this target can use the 'install' target in
-     a simple way:
-
-          install-strip:
-                  $(MAKE) INSTALL_PROGRAM='$(INSTALL_PROGRAM) -s' \
-                          install
-
-     But if the package installs scripts as well as real executables,
-     the 'install-strip' target can't just refer to the 'install'
-     target; it has to strip the executables but not the scripts.
-
-     'install-strip' should not strip the executables in the build
-     directory which are being copied for installation.  It should only
-     strip the copies that are installed.
-
-     Normally we do not recommend stripping an executable unless you are
-     sure the program has no bugs.  However, it can be reasonable to
-     install a stripped executable for actual execution while saving the
-     unstripped executable elsewhere in case there is a bug.
-
-'clean'
-     Delete all files in the current directory that are normally created
-     by building the program.  Also delete files in other directories if
-     they are created by this makefile.  However, don't delete the files
-     that record the configuration.  Also preserve files that could be
-     made by building, but normally aren't because the distribution
-     comes with them.  There is no need to delete parent directories
-     that were created with 'mkdir -p', since they could have existed
-     anyway.
-
-     Delete '.dvi' files here if they are not part of the distribution.
-
-'distclean'
-     Delete all files in the current directory (or created by this
-     makefile) that are created by configuring or building the program.
-     If you have unpacked the source and built the program without
-     creating any other files, 'make distclean' should leave only the
-     files that were in the distribution.  However, there is no need to
-     delete parent directories that were created with 'mkdir -p', since
-     they could have existed anyway.
-
-'mostlyclean'
-     Like 'clean', but may refrain from deleting a few files that people
-     normally don't want to recompile.  For example, the 'mostlyclean'
-     target for GCC does not delete 'libgcc.a', because recompiling it
-     is rarely necessary and takes a lot of time.
-
-'maintainer-clean'
-     Delete almost everything that can be reconstructed with this
-     Makefile.  This typically includes everything deleted by
-     'distclean', plus more: C source files produced by Bison, tags
-     tables, Info files, and so on.
-
-     The reason we say "almost everything" is that running the command
-     'make maintainer-clean' should not delete 'configure' even if
-     'configure' can be remade using a rule in the Makefile.  More
-     generally, 'make maintainer-clean' should not delete anything that
-     needs to exist in order to run 'configure' and then begin to build
-     the program.  Also, there is no need to delete parent directories
-     that were created with 'mkdir -p', since they could have existed
-     anyway.  These are the only exceptions; 'maintainer-clean' should
-     delete everything else that can be rebuilt.
-
-     The 'maintainer-clean' target is intended to be used by a
-     maintainer of the package, not by ordinary users.  You may need
-     special tools to reconstruct some of the files that 'make
-     maintainer-clean' deletes.  Since these files are normally included
-     in the distribution, we don't take care to make them easy to
-     reconstruct.  If you find you need to unpack the full distribution
-     again, don't blame us.
-
-     To help make users aware of this, the commands for the special
-     'maintainer-clean' target should start with these two:
-
-          @echo 'This command is intended for maintainers to use; it'
-          @echo 'deletes files that may need special tools to rebuild.'
-
-'TAGS'
-     Update a tags table for this program.
-
-'info'
-     Generate any Info files needed.  The best way to write the rules is
-     as follows:
-
-          info: foo.info
-
-          foo.info: foo.texi chap1.texi chap2.texi
-                  $(MAKEINFO) $(srcdir)/foo.texi
-
-     You must define the variable 'MAKEINFO' in the Makefile.  It should
-     run the 'makeinfo' program, which is part of the Texinfo
-     distribution.
-
-     Normally a GNU distribution comes with Info files, and that means
-     the Info files are present in the source directory.  Therefore, the
-     Make rule for an info file should update it in the source
-     directory.  When users build the package, ordinarily Make will not
-     update the Info files because they will already be up to date.
-
-'dvi'
-'html'
-'pdf'
-'ps'
-     Generate documentation files in the given format.  These targets
-     should always exist, but any or all can be a no-op if the given
-     output format cannot be generated.  These targets should not be
-     dependencies of the 'all' target; the user must manually invoke
-     them.
-
-     Here's an example rule for generating DVI files from Texinfo:
-
-          dvi: foo.dvi
-
-          foo.dvi: foo.texi chap1.texi chap2.texi
-                  $(TEXI2DVI) $(srcdir)/foo.texi
-
-     You must define the variable 'TEXI2DVI' in the Makefile.  It should
-     run the program 'texi2dvi', which is part of the Texinfo
-     distribution.  ('texi2dvi' uses TeX to do the real work of
-     formatting.  TeX is not distributed with Texinfo.)  Alternatively,
-     write only the dependencies, and allow GNU 'make' to provide the
-     command.
-
-     Here's another example, this one for generating HTML from Texinfo:
-
-          html: foo.html
-
-          foo.html: foo.texi chap1.texi chap2.texi
-                  $(TEXI2HTML) $(srcdir)/foo.texi
-
-     Again, you would define the variable 'TEXI2HTML' in the Makefile;
-     for example, it might run 'makeinfo --no-split --html' ('makeinfo'
-     is part of the Texinfo distribution).
-
-'dist'
-     Create a distribution tar file for this program.  The tar file
-     should be set up so that the file names in the tar file start with
-     a subdirectory name which is the name of the package it is a
-     distribution for.  This name can include the version number.
-
-     For example, the distribution tar file of GCC version 1.40 unpacks
-     into a subdirectory named 'gcc-1.40'.
-
-     The easiest way to do this is to create a subdirectory
-     appropriately named, use 'ln' or 'cp' to install the proper files
-     in it, and then 'tar' that subdirectory.
-
-     Compress the tar file with 'gzip'.  For example, the actual
-     distribution file for GCC version 1.40 is called 'gcc-1.40.tar.gz'.
-     It is ok to support other free compression formats as well.
-
-     The 'dist' target should explicitly depend on all non-source files
-     that are in the distribution, to make sure they are up to date in
-     the distribution.  *Note Making Releases: (standards)Releases.
-
-'check'
-     Perform self-tests (if any).  The user must build the program
-     before running the tests, but need not install the program; you
-     should write the self-tests so that they work when the program is
-     built but not installed.
-
-   The following targets are suggested as conventional names, for
-programs in which they are useful.
-
-'installcheck'
-     Perform installation tests (if any).  The user must build and
-     install the program before running the tests.  You should not
-     assume that '$(bindir)' is in the search path.
-
-'installdirs'
-     It's useful to add a target named 'installdirs' to create the
-     directories where files are installed, and their parent
-     directories.  There is a script called 'mkinstalldirs' which is
-     convenient for this; you can find it in the Gnulib package.  You
-     can use a rule like this:
-
-          # Make sure all installation directories (e.g. $(bindir))
-          # actually exist by making them if necessary.
-          installdirs: mkinstalldirs
-                  $(srcdir)/mkinstalldirs $(bindir) $(datadir) \
-                                          $(libdir) $(infodir) \
-                                          $(mandir)
-
-     or, if you wish to support 'DESTDIR' (strongly encouraged),
-
-          # Make sure all installation directories (e.g. $(bindir))
-          # actually exist by making them if necessary.
-          installdirs: mkinstalldirs
-                  $(srcdir)/mkinstalldirs \
-                      $(DESTDIR)$(bindir) $(DESTDIR)$(datadir) \
-                      $(DESTDIR)$(libdir) $(DESTDIR)$(infodir) \
-                      $(DESTDIR)$(mandir)
-
-     This rule should not modify the directories where compilation is
-     done.  It should do nothing but create installation directories.

-
-16.7 Install Command Categories
-===============================
-
-When writing the 'install' target, you must classify all the commands
-into three categories: normal ones, "pre-installation" commands and
-"post-installation" commands.
-
-   Normal commands move files into their proper places, and set their
-modes.  They may not alter any files except the ones that come entirely
-from the package they belong to.
-
-   Pre-installation and post-installation commands may alter other
-files; in particular, they can edit global configuration files or data
-bases.
-
-   Pre-installation commands are typically executed before the normal
-commands, and post-installation commands are typically run after the
-normal commands.
-
-   The most common use for a post-installation command is to run
-'install-info'.  This cannot be done with a normal command, since it
-alters a file (the Info directory) which does not come entirely and
-solely from the package being installed.  It is a post-installation
-command because it needs to be done after the normal command which
-installs the package's Info files.
-
-   Most programs don't need any pre-installation commands, but we have
-the feature just in case it is needed.
-
-   To classify the commands in the 'install' rule into these three
-categories, insert "category lines" among them.  A category line
-specifies the category for the commands that follow.
-
-   A category line consists of a tab and a reference to a special Make
-variable, plus an optional comment at the end.  There are three
-variables you can use, one for each category; the variable name
-specifies the category.  Category lines are no-ops in ordinary execution
-because these three Make variables are normally undefined (and you
-_should not_ define them in the makefile).
-
-   Here are the three possible category lines, each with a comment that
-explains what it means:
-
-             $(PRE_INSTALL)     # Pre-install commands follow.
-             $(POST_INSTALL)    # Post-install commands follow.
-             $(NORMAL_INSTALL)  # Normal commands follow.
-
-   If you don't use a category line at the beginning of the 'install'
-rule, all the commands are classified as normal until the first category
-line.  If you don't use any category lines, all the commands are
-classified as normal.
-
-   These are the category lines for 'uninstall':
-
-             $(PRE_UNINSTALL)     # Pre-uninstall commands follow.
-             $(POST_UNINSTALL)    # Post-uninstall commands follow.
-             $(NORMAL_UNINSTALL)  # Normal commands follow.
-
-   Typically, a pre-uninstall command would be used for deleting entries
-from the Info directory.
-
-   If the 'install' or 'uninstall' target has any dependencies which act
-as subroutines of installation, then you should start _each_
-dependency's commands with a category line, and start the main target's
-commands with a category line also.  This way, you can ensure that each
-command is placed in the right category regardless of which of the
-dependencies actually run.
-
-   Pre-installation and post-installation commands should not run any
-programs except for these:
-
-     [ basename bash cat chgrp chmod chown cmp cp dd diff echo
-     egrep expand expr false fgrep find getopt grep gunzip gzip
-     hostname install install-info kill ldconfig ln ls md5sum
-     mkdir mkfifo mknod mv printenv pwd rm rmdir sed sort tee
-     test touch true uname xargs yes
-
-   The reason for distinguishing the commands in this way is for the
-sake of making binary packages.  Typically a binary package contains all
-the executables and other files that need to be installed, and has its
-own method of installing them--so it does not need to run the normal
-installation commands.  But installing the binary package does need to
-execute the pre-installation and post-installation commands.
-
-   Programs to build binary packages work by extracting the
-pre-installation and post-installation commands.  Here is one way of
-extracting the pre-installation commands (the '-s' option to 'make' is
-needed to silence messages about entering subdirectories):
-
-     make -s -n install -o all \
-           PRE_INSTALL=pre-install \
-           POST_INSTALL=post-install \
-           NORMAL_INSTALL=normal-install \
-       | gawk -f pre-install.awk
-
-where the file 'pre-install.awk' could contain this:
-
-     $0 ~ /^(normal-install|post-install)[ \t]*$/ {on = 0}
-     on {print $0}
-     $0 ~ /^pre-install[ \t]*$/ {on = 1}

-     *Note The 'eval' Function: Eval Function.
-
-'$(file OP FILENAME,TEXT)'
-     Expand the arguments, then open the file FILENAME using mode OP and
-     write TEXT to that file.
-     *Note The 'file' Function: File Function.
-
-'$(value VAR)'
-     Evaluates to the contents of the variable VAR, with no expansion
-     performed on it.
-     *Note The 'value' Function: Value Function.
-
-   Here is a summary of the automatic variables.  *Note Automatic
-Variables::, for full information.
-
-'$@'
-     The file name of the target.
-
-'$%'
-     The target member name, when the target is an archive member.
-
-'$<'
-     The name of the first prerequisite.
-
-'$?'
-     The names of all the prerequisites that are newer than the target,
-     with spaces between them.  For prerequisites which are archive
-     members, only the named member is used (*note Archives::).
-
-'$^'
-'$+'
-     The names of all the prerequisites, with spaces between them.  For
-     prerequisites which are archive members, only the named member is
-     used (*note Archives::).  The value of '$^' omits duplicate
-     prerequisites, while '$+' retains them and preserves their order.
-
-'$*'
-     The stem with which an implicit rule matches (*note How Patterns
-     Match: Pattern Match.).
-
-'$(@D)'
-'$(@F)'
-     The directory part and the file-within-directory part of '$@'.
-
-'$(*D)'
-'$(*F)'
-     The directory part and the file-within-directory part of '$*'.
-
-'$(%D)'
-'$(%F)'
-     The directory part and the file-within-directory part of '$%'.
-
-'$(<D)'
-'$(<F)'
-     The directory part and the file-within-directory part of '$<'.
-
-'$(^D)'
-'$(^F)'
-     The directory part and the file-within-directory part of '$^'.
-
-'$(+D)'
-'$(+F)'
-     The directory part and the file-within-directory part of '$+'.
-
-'$(?D)'
-'$(?F)'
-     The directory part and the file-within-directory part of '$?'.
-
-   These variables are used specially by GNU 'make':
-
-'MAKEFILES'
-
-     Makefiles to be read on every invocation of 'make'.
-     *Note The Variable 'MAKEFILES': MAKEFILES Variable.
-
-'VPATH'
-
-     Directory search path for files not found in the current directory.
-     *Note 'VPATH' Search Path for All Prerequisites: General Search.
-
-'SHELL'
-
-     The name of the system default command interpreter, usually
-     '/bin/sh'.  You can set 'SHELL' in the makefile to change the shell
-     used to run recipes.  *Note Recipe Execution: Execution.  The
-     'SHELL' variable is handled specially when importing from and
-     exporting to the environment.  *Note Choosing the Shell::.
-
-'MAKESHELL'
-
-     On MS-DOS only, the name of the command interpreter that is to be
-     used by 'make'.  This value takes precedence over the value of
-     'SHELL'.  *Note MAKESHELL variable: Execution.
-
-'MAKE'
-
-     The name with which 'make' was invoked.  Using this variable in
-     recipes has special meaning.  *Note How the 'MAKE' Variable Works:
-     MAKE Variable.
-
-'MAKE_VERSION'
-
-     The built-in variable 'MAKE_VERSION' expands to the version number
-     of the GNU 'make' program.
-
-'MAKE_HOST'
-
-     The built-in variable 'MAKE_HOST' expands to a string representing
-     the host that GNU 'make' was built to run on.
-
-'MAKELEVEL'
-
-     The number of levels of recursion (sub-'make's).
-     *Note Variables/Recursion::.
-
-'MAKEFLAGS'
-
-     The flags given to 'make'.  You can set this in the environment or
-     a makefile to set flags.
-     *Note Communicating Options to a Sub-'make': Options/Recursion.
-
-     It is _never_ appropriate to use 'MAKEFLAGS' directly in a recipe
-     line: its contents may not be quoted correctly for use in the
-     shell.  Always allow recursive 'make''s to obtain these values
-     through the environment from its parent.
-
-'GNUMAKEFLAGS'
-
-     Other flags parsed by 'make'.  You can set this in the environment
-     or a makefile to set 'make' command-line flags.  GNU 'make' never
-     sets this variable itself.  This variable is only needed if you'd
-     like to set GNU 'make'-specific flags in a POSIX-compliant
-     makefile.  This variable will be seen by GNU 'make' and ignored by
-     other 'make' implementations.  It's not needed if you only use GNU
-     'make'; just use 'MAKEFLAGS' directly.  *Note Communicating Options
-     to a Sub-'make': Options/Recursion.
-
-'MAKECMDGOALS'
-
-     The targets given to 'make' on the command line.  Setting this
-     variable has no effect on the operation of 'make'.
-     *Note Arguments to Specify the Goals: Goals.
-
-'CURDIR'
-
-     Set to the absolute pathname of the current working directory
-     (after all '-C' options are processed, if any).  Setting this
-     variable has no effect on the operation of 'make'.
-     *Note Recursive Use of 'make': Recursion.
-
-'SUFFIXES'
-
-     The default list of suffixes before 'make' reads any makefiles.
-
-'.LIBPATTERNS'
-     Defines the naming of the libraries 'make' searches for, and their
-     order.
-     *Note Directory Search for Link Libraries: Libraries/Search.

-Appendix B Errors Generated by Make
-***********************************
-
-Here is a list of the more common errors you might see generated by
-'make', and some information about what they mean and how to fix them.
-
-   Sometimes 'make' errors are not fatal, especially in the presence of
-a '-' prefix on a recipe line, or the '-k' command line option.  Errors
-that are fatal are prefixed with the string '***'.
-
-   Error messages are all either prefixed with the name of the program
-(usually 'make'), or, if the error is found in a makefile, the name of
-the file and line number containing the problem.
-
-   In the table below, these common prefixes are left off.
-
-'[FOO] Error NN'
-'[FOO] SIGNAL DESCRIPTION'
-     These errors are not really 'make' errors at all.  They mean that a
-     program that 'make' invoked as part of a recipe returned a non-0
-     error code ('Error NN'), which 'make' interprets as failure, or it
-     exited in some other abnormal fashion (with a signal of some type).
-     *Note Errors in Recipes: Errors.
-
-     If no '***' is attached to the message, then the sub-process failed
-     but the rule in the makefile was prefixed with the '-' special
-     character, so 'make' ignored the error.
-
-'missing separator. Stop.'
-'missing separator (did you mean TAB instead of 8 spaces?). Stop.'
-     This means that 'make' could not understand much of anything about
-     the makefile line it just read.  GNU 'make' looks for various
-     separators (':', '=', recipe prefix characters, etc.)  to indicate
-     what kind of line it's parsing.  This message means it couldn't
-     find a valid one.
-
-     One of the most common reasons for this message is that you (or
-     perhaps your oh-so-helpful editor, as is the case with many
-     MS-Windows editors) have attempted to indent your recipe lines with
-     spaces instead of a tab character.  In this case, 'make' will use
-     the second form of the error above.  Remember that every line in
-     the recipe must begin with a tab character (unless you set
-     '.RECIPEPREFIX'; *note Special Variables::).  Eight spaces do not
-     count.  *Note Rule Syntax::.
-
-'recipe commences before first target. Stop.'
-'missing rule before recipe. Stop.'
-     This means the first thing in the makefile seems to be part of a
-     recipe: it begins with a recipe prefix character and doesn't appear
-     to be a legal 'make' directive (such as a variable assignment).
-     Recipes must always be associated with a target.
-
-     The second form is generated if the line has a semicolon as the
-     first non-whitespace character; 'make' interprets this to mean you
-     left out the "target: prerequisite" section of a rule.  *Note Rule
-     Syntax::.
-
-'No rule to make target `XXX'.'
-'No rule to make target `XXX', needed by `YYY'.'
-     This means that 'make' decided it needed to build a target, but
-     then couldn't find any instructions in the makefile on how to do
-     that, either explicit or implicit (including in the default rules
-     database).
-
-     If you want that file to be built, you will need to add a rule to
-     your makefile describing how that target can be built.  Other
-     possible sources of this problem are typos in the makefile (if that
-     file name is wrong) or a corrupted source tree (if that file is not
-     supposed to be built, but rather only a prerequisite).
-
-'No targets specified and no makefile found. Stop.'
-'No targets. Stop.'
-     The former means that you didn't provide any targets to be built on
-     the command line, and 'make' couldn't find any makefiles to read
-     in.  The latter means that some makefile was found, but it didn't
-     contain any default goal and none was given on the command line.
-     GNU 'make' has nothing to do in these situations.  *Note Arguments
-     to Specify the Makefile: Makefile Arguments.
-
-'Makefile `XXX' was not found.'
-'Included makefile `XXX' was not found.'
-     A makefile specified on the command line (first form) or included
-     (second form) was not found.
-
-'warning: overriding recipe for target `XXX''
-'warning: ignoring old recipe for target `XXX''
-     GNU 'make' allows only one recipe to be specified per target
-     (except for double-colon rules).  If you give a recipe for a target
-     which already has been defined to have one, this warning is issued
-     and the second recipe will overwrite the first.  *Note Multiple
-     Rules for One Target: Multiple Rules.
-
-'Circular XXX <- YYY dependency dropped.'
-     This means that 'make' detected a loop in the dependency graph:
-     after tracing the prerequisite YYY of target XXX, and its
-     prerequisites, etc., one of them depended on XXX again.
-
-'Recursive variable `XXX' references itself (eventually). Stop.'
-     This means you've defined a normal (recursive) 'make' variable XXX
-     that, when it's expanded, will refer to itself (XXX).  This is not
-     allowed; either use simply-expanded variables (':=' or '::=') or
-     use the append operator ('+=').  *Note How to Use Variables: Using
-     Variables.
-
-'Unterminated variable reference. Stop.'
-     This means you forgot to provide the proper closing parenthesis or
-     brace in your variable or function reference.
-
-'insufficient arguments to function `XXX'. Stop.'
-     This means you haven't provided the requisite number of arguments
-     for this function.  See the documentation of the function for a
-     description of its arguments.  *Note Functions for Transforming
-     Text: Functions.
-
-'missing target pattern. Stop.'
-'multiple target patterns. Stop.'
-'target pattern contains no `%'. Stop.'
-'mixed implicit and static pattern rules. Stop.'
-     These errors are generated for malformed static pattern rules
-     (*note Syntax of Static Pattern Rules: Static Usage.).  The first
-     means the target-pattern part of the rule is empty; the second
-     means there are multiple pattern characters ('%') in the
-     target-pattern part; the third means there are no pattern
-     characters in the target-pattern part; and the fourth means that
-     all three parts of the static pattern rule contain pattern
-     characters ('%')-the first part should not contain pattern
-     characters.
-
-     If you see these errors and you aren't trying to create a static
-     pattern rule, check the value of any variables in your target and
-     prerequisite lists to be sure they do not contain colons.
-
-'warning: -jN forced in submake: disabling jobserver mode.'
-     This warning and the next are generated if 'make' detects error
-     conditions related to parallel processing on systems where
-     sub-'make's can communicate (*note Communicating Options to a
-     Sub-'make': Options/Recursion.).  This warning is generated if a
-     recursive invocation of a 'make' process is forced to have '-jN' in
-     its argument list (where N is greater than one).  This could
-     happen, for example, if you set the 'MAKE' environment variable to
-     'make -j2'.  In this case, the sub-'make' doesn't communicate with
-     other 'make' processes and will simply pretend it has two jobs of
-     its own.
-
-'warning: jobserver unavailable: using -j1. Add `+' to parent make rule.'
-     In order for 'make' processes to communicate, the parent will pass
-     information to the child.  Since this could result in problems if
-     the child process isn't actually a 'make', the parent will only do
-     this if it thinks the child is a 'make'.  The parent uses the
-     normal algorithms to determine this (*note How the 'MAKE' Variable
-     Works: MAKE Variable.).  If the makefile is constructed such that
-     the parent doesn't know the child is a 'make' process, then the
-     child will receive only part of the information necessary.  In this
-     case, the child will generate this warning message and proceed with
-     its build in a sequential manner.
-
-'warning: ignoring prerequisites on suffix rule definition'
-     According to POSIX, a suffix rule cannot contain prerequisites.  If
-     a rule that could be a suffix rule has prerequisites it is
-     interpreted as a simple explicit rule, with an odd target name.
-     This requirement is obeyed when POSIX-conforming mode is enabled
-     (the '.POSIX' target is defined).  In versions of GNU 'make' prior
-     to 4.3, no warning was emitted and a suffix rule was created,
-     however all prerequisites were ignored and were not part of the
-     suffix rule.  Starting with GNU 'make' 4.3 the behavior is the
-     same, and in addition this warning is generated.  In a future
-     version the POSIX-conforming behavior will be the only behavior: no
-     rule with a prerequisite can be suffix rule and this warning will
-     be removed.

-Appendix C Complex Makefile Example
-***********************************
-
-Here is the makefile for the GNU 'tar' program.  This is a moderately
-complex makefile.  The first line uses a '#!' setting to allow the
-makefile to be executed directly.
-
-   Because it is the first target, the default goal is 'all'.  An
-interesting feature of this makefile is that 'testpad.h' is a source
-file automatically created by the 'testpad' program, itself compiled
-from 'testpad.c'.
-
-   If you type 'make' or 'make all', then 'make' creates the 'tar'
-executable, the 'rmt' daemon that provides remote tape access, and the
-'tar.info' Info file.
-
-   If you type 'make install', then 'make' not only creates 'tar',
-'rmt', and 'tar.info', but also installs them.
-
-   If you type 'make clean', then 'make' removes the '.o' files, and the
-'tar', 'rmt', 'testpad', 'testpad.h', and 'core' files.
-
-   If you type 'make distclean', then 'make' not only removes the same
-files as does 'make clean' but also the 'TAGS', 'Makefile', and
-'config.status' files.  (Although it is not evident, this makefile (and
-'config.status') is generated by the user with the 'configure' program,
-which is provided in the 'tar' distribution, but is not shown here.)
-
-   If you type 'make realclean', then 'make' removes the same files as
-does 'make distclean' and also removes the Info files generated from
-'tar.texinfo'.
-
-   In addition, there are targets 'shar' and 'dist' that create
-distribution kits.

-                     Version 1.3, 3 November 2008
-
-     Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
-     <https://fsf.org/>
-
-     Everyone is permitted to copy and distribute verbatim copies
-     of this license document, but changing it is not allowed.
-
-  0. PREAMBLE
-
-     The purpose of this License is to make a manual, textbook, or other
-     functional and useful document "free" in the sense of freedom: to
-     assure everyone the effective freedom to copy and redistribute it,
-     with or without modifying it, either commercially or
-     noncommercially.  Secondarily, this License preserves for the
-     author and publisher a way to get credit for their work, while not
-     being considered responsible for modifications made by others.
-
-     This License is a kind of "copyleft", which means that derivative
-     works of the document must themselves be free in the same sense.
-     It complements the GNU General Public License, which is a copyleft
-     license designed for free software.
-
-     We have designed this License in order to use it for manuals for
-     free software, because free software needs free documentation: a
-     free program should come with manuals providing the same freedoms
-     that the software does.  But this License is not limited to
-     software manuals; it can be used for any textual work, regardless
-     of subject matter or whether it is published as a printed book.  We
-     recommend this License principally for works whose purpose is
-     instruction or reference.
-
-  1. APPLICABILITY AND DEFINITIONS
-
-     This License applies to any manual or other work, in any medium,
-     that contains a notice placed by the copyright holder saying it can
-     be distributed under the terms of this License.  Such a notice
-     grants a world-wide, royalty-free license, unlimited in duration,
-     to use that work under the conditions stated herein.  The
-     "Document", below, refers to any such manual or work.  Any member
-     of the public is a licensee, and is addressed as "you".  You accept
-     the license if you copy, modify or distribute the work in a way
-     requiring permission under copyright law.
-
-     A "Modified Version" of the Document means any work containing the
-     Document or a portion of it, either copied verbatim, or with
-     modifications and/or translated into another language.
-
-     A "Secondary Section" is a named appendix or a front-matter section
-     of the Document that deals exclusively with the relationship of the
-     publishers or authors of the Document to the Document's overall
-     subject (or to related matters) and contains nothing that could
-     fall directly within that overall subject.  (Thus, if the Document
-     is in part a textbook of mathematics, a Secondary Section may not
-     explain any mathematics.)  The relationship could be a matter of
-     historical connection with the subject or with related matters, or
-     of legal, commercial, philosophical, ethical or political position
-     regarding them.
-
-     The "Invariant Sections" are certain Secondary Sections whose
-     titles are designated, as being those of Invariant Sections, in the
-     notice that says that the Document is released under this License.
-     If a section does not fit the above definition of Secondary then it
-     is not allowed to be designated as Invariant.  The Document may
-     contain zero Invariant Sections.  If the Document does not identify
-     any Invariant Sections then there are none.
-
-     The "Cover Texts" are certain short passages of text that are
-     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
-     that says that the Document is released under this License.  A
-     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
-     be at most 25 words.
-
-     A "Transparent" copy of the Document means a machine-readable copy,
-     represented in a format whose specification is available to the
-     general public, that is suitable for revising the document
-     straightforwardly with generic text editors or (for images composed
-     of pixels) generic paint programs or (for drawings) some widely
-     available drawing editor, and that is suitable for input to text
-     formatters or for automatic translation to a variety of formats
-     suitable for input to text formatters.  A copy made in an otherwise
-     Transparent file format whose markup, or absence of markup, has
-     been arranged to thwart or discourage subsequent modification by
-     readers is not Transparent.  An image format is not Transparent if
-     used for any substantial amount of text.  A copy that is not
-     "Transparent" is called "Opaque".
-
-     Examples of suitable formats for Transparent copies include plain
-     ASCII without markup, Texinfo input format, LaTeX input format,
-     SGML or XML using a publicly available DTD, and standard-conforming
-     simple HTML, PostScript or PDF designed for human modification.
-     Examples of transparent image formats include PNG, XCF and JPG.
-     Opaque formats include proprietary formats that can be read and
-     edited only by proprietary word processors, SGML or XML for which
-     the DTD and/or processing tools are not generally available, and
-     the machine-generated HTML, PostScript or PDF produced by some word
-     processors for output purposes only.
-
-     The "Title Page" means, for a printed book, the title page itself,
-     plus such following pages as are needed to hold, legibly, the
-     material this License requires to appear in the title page.  For
-     works in formats which do not have any title page as such, "Title
-     Page" means the text near the most prominent appearance of the
-     work's title, preceding the beginning of the body of the text.
-
-     The "publisher" means any person or entity that distributes copies
-     of the Document to the public.
-
-     A section "Entitled XYZ" means a named subunit of the Document
-     whose title either is precisely XYZ or contains XYZ in parentheses
-     following text that translates XYZ in another language.  (Here XYZ
-     stands for a specific section name mentioned below, such as
-     "Acknowledgements", "Dedications", "Endorsements", or "History".)
-     To "Preserve the Title" of such a section when you modify the
-     Document means that it remains a section "Entitled XYZ" according
-     to this definition.
-
-     The Document may include Warranty Disclaimers next to the notice
-     which states that this License applies to the Document.  These
-     Warranty Disclaimers are considered to be included by reference in
-     this License, but only as regards disclaiming warranties: any other
-     implication that these Warranty Disclaimers may have is void and
-     has no effect on the meaning of this License.
-
-  2. VERBATIM COPYING
-
-     You may copy and distribute the Document in any medium, either
-     commercially or noncommercially, provided that this License, the
-     copyright notices, and the license notice saying this License
-     applies to the Document are reproduced in all copies, and that you
-     add no other conditions whatsoever to those of this License.  You
-     may not use technical measures to obstruct or control the reading
-     or further copying of the copies you make or distribute.  However,
-     you may accept compensation in exchange for copies.  If you
-     distribute a large enough number of copies you must also follow the
-     conditions in section 3.
-
-     You may also lend copies, under the same conditions stated above,
-     and you may publicly display copies.
-
-  3. COPYING IN QUANTITY
-
-     If you publish printed copies (or copies in media that commonly
-     have printed covers) of the Document, numbering more than 100, and
-     the Document's license notice requires Cover Texts, you must
-     enclose the copies in covers that carry, clearly and legibly, all
-     these Cover Texts: Front-Cover Texts on the front cover, and
-     Back-Cover Texts on the back cover.  Both covers must also clearly
-     and legibly identify you as the publisher of these copies.  The
-     front cover must present the full title with all words of the title
-     equally prominent and visible.  You may add other material on the
-     covers in addition.  Copying with changes limited to the covers, as
-     long as they preserve the title of the Document and satisfy these
-     conditions, can be treated as verbatim copying in other respects.
-
-     If the required texts for either cover are too voluminous to fit
-     legibly, you should put the first ones listed (as many as fit
-     reasonably) on the actual cover, and continue the rest onto
-     adjacent pages.
-
-     If you publish or distribute Opaque copies of the Document
-     numbering more than 100, you must either include a machine-readable
-     Transparent copy along with each Opaque copy, or state in or with
-     each Opaque copy a computer-network location from which the general
-     network-using public has access to download using public-standard
-     network protocols a complete Transparent copy of the Document, free
-     of added material.  If you use the latter option, you must take
-     reasonably prudent steps, when you begin distribution of Opaque
-     copies in quantity, to ensure that this Transparent copy will
-     remain thus accessible at the stated location until at least one
-     year after the last time you distribute an Opaque copy (directly or
-     through your agents or retailers) of that edition to the public.
-
-     It is requested, but not required, that you contact the authors of
-     the Document well before redistributing any large number of copies,
-     to give them a chance to provide you with an updated version of the
-     Document.
-
-  4. MODIFICATIONS
-
-     You may copy and distribute a Modified Version of the Document
-     under the conditions of sections 2 and 3 above, provided that you
-     release the Modified Version under precisely this License, with the
-     Modified Version filling the role of the Document, thus licensing
-     distribution and modification of the Modified Version to whoever
-     possesses a copy of it.  In addition, you must do these things in
-     the Modified Version:
-
-       A. Use in the Title Page (and on the covers, if any) a title
-          distinct from that of the Document, and from those of previous
-          versions (which should, if there were any, be listed in the
-          History section of the Document).  You may use the same title
-          as a previous version if the original publisher of that
-          version gives permission.
-
-       B. List on the Title Page, as authors, one or more persons or
-          entities responsible for authorship of the modifications in
-          the Modified Version, together with at least five of the
-          principal authors of the Document (all of its principal
-          authors, if it has fewer than five), unless they release you
-          from this requirement.
-
-       C. State on the Title page the name of the publisher of the
-          Modified Version, as the publisher.
-
-       D. Preserve all the copyright notices of the Document.
-
-       E. Add an appropriate copyright notice for your modifications
-          adjacent to the other copyright notices.
-
-       F. Include, immediately after the copyright notices, a license
-          notice giving the public permission to use the Modified
-          Version under the terms of this License, in the form shown in
-          the Addendum below.
-
-       G. Preserve in that license notice the full lists of Invariant
-          Sections and required Cover Texts given in the Document's
-          license notice.
-
-       H. Include an unaltered copy of this License.
-
-       I. Preserve the section Entitled "History", Preserve its Title,
-          and add to it an item stating at least the title, year, new
-          authors, and publisher of the Modified Version as given on the
-          Title Page.  If there is no section Entitled "History" in the
-          Document, create one stating the title, year, authors, and
-          publisher of the Document as given on its Title Page, then add
-          an item describing the Modified Version as stated in the
-          previous sentence.
-
-       J. Preserve the network location, if any, given in the Document
-          for public access to a Transparent copy of the Document, and
-          likewise the network locations given in the Document for
-          previous versions it was based on.  These may be placed in the
-          "History" section.  You may omit a network location for a work
-          that was published at least four years before the Document
-          itself, or if the original publisher of the version it refers
-          to gives permission.
-
-       K. For any section Entitled "Acknowledgements" or "Dedications",
-          Preserve the Title of the section, and preserve in the section
-          all the substance and tone of each of the contributor
-          acknowledgements and/or dedications given therein.
-
-       L. Preserve all the Invariant Sections of the Document, unaltered
-          in their text and in their titles.  Section numbers or the
-          equivalent are not considered part of the section titles.
-
-       M. Delete any section Entitled "Endorsements".  Such a section
-          may not be included in the Modified Version.
-
-       N. Do not retitle any existing section to be Entitled
-          "Endorsements" or to conflict in title with any Invariant
-          Section.
-
-       O. Preserve any Warranty Disclaimers.
-
-     If the Modified Version includes new front-matter sections or
-     appendices that qualify as Secondary Sections and contain no
-     material copied from the Document, you may at your option designate
-     some or all of these sections as invariant.  To do this, add their
-     titles to the list of Invariant Sections in the Modified Version's
-     license notice.  These titles must be distinct from any other
-     section titles.
-
-     You may add a section Entitled "Endorsements", provided it contains
-     nothing but endorsements of your Modified Version by various
-     parties--for example, statements of peer review or that the text
-     has been approved by an organization as the authoritative
-     definition of a standard.
-
-     You may add a passage of up to five words as a Front-Cover Text,
-     and a passage of up to 25 words as a Back-Cover Text, to the end of
-     the list of Cover Texts in the Modified Version.  Only one passage
-     of Front-Cover Text and one of Back-Cover Text may be added by (or
-     through arrangements made by) any one entity.  If the Document
-     already includes a cover text for the same cover, previously added
-     by you or by arrangement made by the same entity you are acting on
-     behalf of, you may not add another; but you may replace the old
-     one, on explicit permission from the previous publisher that added
-     the old one.
-
-     The author(s) and publisher(s) of the Document do not by this
-     License give permission to use their names for publicity for or to
-     assert or imply endorsement of any Modified Version.
-
-  5. COMBINING DOCUMENTS
-
-     You may combine the Document with other documents released under
-     this License, under the terms defined in section 4 above for
-     modified versions, provided that you include in the combination all
-     of the Invariant Sections of all of the original documents,
-     unmodified, and list them all as Invariant Sections of your
-     combined work in its license notice, and that you preserve all
-     their Warranty Disclaimers.
-
-     The combined work need only contain one copy of this License, and
-     multiple identical Invariant Sections may be replaced with a single
-     copy.  If there are multiple Invariant Sections with the same name
-     but different contents, make the title of each such section unique
-     by adding at the end of it, in parentheses, the name of the
-     original author or publisher of that section if known, or else a
-     unique number.  Make the same adjustment to the section titles in
-     the list of Invariant Sections in the license notice of the
-     combined work.
-
-     In the combination, you must combine any sections Entitled
-     "History" in the various original documents, forming one section
-     Entitled "History"; likewise combine any sections Entitled
-     "Acknowledgements", and any sections Entitled "Dedications".  You
-     must delete all sections Entitled "Endorsements."
-
-  6. COLLECTIONS OF DOCUMENTS
-
-     You may make a collection consisting of the Document and other
-     documents released under this License, and replace the individual
-     copies of this License in the various documents with a single copy
-     that is included in the collection, provided that you follow the
-     rules of this License for verbatim copying of each of the documents
-     in all other respects.
-
-     You may extract a single document from such a collection, and
-     distribute it individually under this License, provided you insert
-     a copy of this License into the extracted document, and follow this
-     License in all other respects regarding verbatim copying of that
-     document.
-
-  7. AGGREGATION WITH INDEPENDENT WORKS
-
-     A compilation of the Document or its derivatives with other
-     separate and independent documents or works, in or on a volume of a
-     storage or distribution medium, is called an "aggregate" if the
-     copyright resulting from the compilation is not used to limit the
-     legal rights of the compilation's users beyond what the individual
-     works permit.  When the Document is included in an aggregate, this
-     License does not apply to the other works in the aggregate which
-     are not themselves derivative works of the Document.
-
-     If the Cover Text requirement of section 3 is applicable to these
-     copies of the Document, then if the Document is less than one half
-     of the entire aggregate, the Document's Cover Texts may be placed
-     on covers that bracket the Document within the aggregate, or the
-     electronic equivalent of covers if the Document is in electronic
-     form.  Otherwise they must appear on printed covers that bracket
-     the whole aggregate.
-
-  8. TRANSLATION
-
-     Translation is considered a kind of modification, so you may
-     distribute translations of the Document under the terms of section
-     4.  Replacing Invariant Sections with translations requires special
-     permission from their copyright holders, but you may include
-     translations of some or all Invariant Sections in addition to the
-     original versions of these Invariant Sections.  You may include a
-     translation of this License, and all the license notices in the
-     Document, and any Warranty Disclaimers, provided that you also
-     include the original English version of this License and the
-     original versions of those notices and disclaimers.  In case of a
-     disagreement between the translation and the original version of
-     this License or a notice or disclaimer, the original version will
-     prevail.
-
-     If a section in the Document is Entitled "Acknowledgements",
-     "Dedications", or "History", the requirement (section 4) to
-     Preserve its Title (section 1) will typically require changing the
-     actual title.
-
-  9. TERMINATION
-
-     You may not copy, modify, sublicense, or distribute the Document
-     except as expressly provided under this License.  Any attempt
-     otherwise to copy, modify, sublicense, or distribute it is void,
-     and will automatically terminate your rights under this License.
-
-     However, if you cease all violation of this License, then your
-     license from a particular copyright holder is reinstated (a)
-     provisionally, unless and until the copyright holder explicitly and
-     finally terminates your license, and (b) permanently, if the
-     copyright holder fails to notify you of the violation by some
-     reasonable means prior to 60 days after the cessation.
-
-     Moreover, your license from a particular copyright holder is
-     reinstated permanently if the copyright holder notifies you of the
-     violation by some reasonable means, this is the first time you have
-     received notice of violation of this License (for any work) from
-     that copyright holder, and you cure the violation prior to 30 days
-     after your receipt of the notice.
-
-     Termination of your rights under this section does not terminate
-     the licenses of parties who have received copies or rights from you
-     under this License.  If your rights have been terminated and not
-     permanently reinstated, receipt of a copy of some or all of the
-     same material does not give you any rights to use it.
-
-  10. FUTURE REVISIONS OF THIS LICENSE
-
-     The Free Software Foundation may publish new, revised versions of
-     the GNU Free Documentation License from time to time.  Such new
-     versions will be similar in spirit to the present version, but may
-     differ in detail to address new problems or concerns.  See
-     <https://www.gnu.org/copyleft/>.
-
-     Each version of the License is given a distinguishing version
-     number.  If the Document specifies that a particular numbered
-     version of this License "or any later version" applies to it, you
-     have the option of following the terms and conditions either of
-     that specified version or of any later version that has been
-     published (not as a draft) by the Free Software Foundation.  If the
-     Document does not specify a version number of this License, you may
-     choose any version ever published (not as a draft) by the Free
-     Software Foundation.  If the Document specifies that a proxy can
-     decide which future versions of this License can be used, that
-     proxy's public statement of acceptance of a version permanently
-     authorizes you to choose that version for the Document.
-
-  11. RELICENSING
-
-     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
-     World Wide Web server that publishes copyrightable works and also
-     provides prominent facilities for anybody to edit those works.  A
-     public wiki that anybody can edit is an example of such a server.
-     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
-     site means any set of copyrightable works thus published on the MMC
-     site.
-
-     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
-     license published by Creative Commons Corporation, a not-for-profit
-     corporation with a principal place of business in San Francisco,
-     California, as well as future copyleft versions of that license
-     published by that same organization.
-
-     "Incorporate" means to publish or republish a Document, in whole or
-     in part, as part of another Document.
-
-     An MMC is "eligible for relicensing" if it is licensed under this
-     License, and if all works that were first published under this
-     License somewhere other than this MMC, and subsequently
-     incorporated in whole or in part into the MMC, (1) had no cover
-     texts or invariant sections, and (2) were thus incorporated prior
-     to November 1, 2008.
-
-     The operator of an MMC Site may republish an MMC contained in the
-     site under CC-BY-SA on the same site at any time before August 1,
-     2009, provided the MMC is eligible for relicensing.

-ADDENDUM: How to use this License for your documents
-====================================================
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and license
-notices just after the title page:
-
-       Copyright (C)  YEAR  YOUR NAME.

-       Texts.  A copy of the license is included in the section entitled ``GNU
-       Free Documentation License''.
-
-   If you have Invariant Sections, Front-Cover Texts and Back-Cover
-Texts, replace the "with...Texts." line with this:
-
-         with the Invariant Sections being LIST THEIR TITLES, with
-         the Front-Cover Texts being LIST, and with the Back-Cover Texts
-         being LIST.
-
-   If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-   If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of free

-@chapter Overview of @code{make}
-
-The @code{make} utility automatically determines which pieces of a large
-program need to be recompiled, and issues commands to recompile them.
-This manual describes GNU @code{make}, which was implemented by Richard
-Stallman and Roland McGrath.  Development since Version 3.76 has been
-handled by Paul D. Smith.
-
-GNU @code{make} conforms to section 6.2 of @cite{IEEE Standard
-1003.2-1992} (POSIX.2).
-@cindex POSIX
-@cindex IEEE Standard 1003.2
-@cindex standards conformance
-
-Our examples show C programs, since they are most common, but you can use
-@code{make} with any programming language whose compiler can be run with a
-shell command.  Indeed, @code{make} is not limited to programs.  You can
-use it to describe any task where some files must be updated automatically
-from others whenever the others change.

-To prepare to use @code{make}, you must write a file called
-the @dfn{makefile} that describes the relationships among files
-in your program and provides commands for updating each file.
-In a program, typically, the executable file is updated from object

-
-If you have problems with GNU @code{make} or think you've found a bug,
-please report it to the developers; we cannot promise to do anything but
-we might well want to fix it.
-
-Before reporting a bug, make sure you've actually found a real bug.
-Carefully reread the documentation and see if it really says you can do
-what you're trying to do.  If it's not clear whether you should be able
-to do something or not, report that too; it's a bug in the
-documentation!
-
-Before reporting a bug or trying to fix it yourself, try to isolate it
-to the smallest possible makefile that reproduces the problem.  Then
-send us the makefile and the exact results @code{make} gave you,
-including any error or warning messages.  Please don't paraphrase
-these messages: it's best to cut and paste them into your report.
-When generating this small makefile, be sure to not use any non-free
-or unusual tools in your recipes: you can almost always emulate what
-such a tool would do with simple shell commands.  Finally, be sure to
-explain what you expected to occur; this will help us decide whether
-the problem was really in the documentation.
-
-Once you have a precise problem you can report it in one of two ways.
-Either send electronic mail to:
-
-@example
-    bug-make@@gnu.org
-@end example
-
-@noindent
-or use our Web-based project management tool, at:
-
-@example
-    http://savannah.gnu.org/projects/make/
-@end example
-
-@noindent
-In addition to the information above, please be careful to include the
-version number of @code{make} you are using.  You can get this
-information with the command @samp{make --version}.  Be sure also to
-include the type of machine and operating system you are using.  One
-way to obtain this information is by looking at the final lines of
-output from the command @samp{make --help}.

-You need a file called a @dfn{makefile} to tell @code{make} what to do.
-Most often, the makefile tells @code{make} how to compile and link a
-program.
-@cindex makefile
-
-In this chapter, we will discuss a simple makefile that describes how to
-compile and link a text editor which consists of eight C source files
-and three header files.  The makefile can also tell @code{make} how to

-certain files as a clean-up operation).  To see a more complex example
-of a makefile, see @ref{Complex Makefile}.
-
-When @code{make} recompiles the editor, each changed C source file
-must be recompiled.  If a header file has changed, each C source file
-that includes the header file must be recompiled to be safe.  Each
-compilation produces an object file corresponding to the source file.
-Finally, if any source file has been recompiled, all the object files,
-whether newly made or saved from previous compilations, must be linked
-together to produce the new executable editor.

-@cindex parts of makefile rule
-
-A simple makefile consists of ``rules'' with the following shape:
-
-@cindex targets, introduction to
-@cindex prerequisites, introduction to
-@cindex recipes, introduction to
-@example
-@group
-@var{target} @dots{} : @var{prerequisites} @dots{}

-        @dots{}
-@end group
-@end example
-
-A @dfn{target} is usually the name of a file that is generated by a
-program; examples of targets are executable or object files.  A target
-can also be the name of an action to carry out, such as @samp{clean}
-(@pxref{Phony Targets}).
-
-A @dfn{prerequisite} is a file that is used as input to create the
-target.  A target often depends on several files.
-
-@cindex tabs in rules
-A @dfn{recipe} is an action that @code{make} carries out.  A recipe
-may have more than one command, either on the same line or each on its
-own line.  @strong{Please note:} you need to put a tab character at
-the beginning of every recipe line!  This is an obscurity that catches
-the unwary.  If you prefer to prefix your recipes with a character
-other than tab, you can set the @code{.RECIPEPREFIX} variable to an
-alternate character (@pxref{Special Variables}).
-
-Usually a recipe is in a rule with prerequisites and serves to create a
-target file if any of the prerequisites change.  However, the rule that
-specifies a recipe for the target need not have prerequisites.  For
-example, the rule containing the delete command associated with the
-target @samp{clean} does not have prerequisites.
-
-A @dfn{rule}, then, explains how and when to remake certain files
-which are the targets of the particular rule.  @code{make} carries out
-the recipe on the prerequisites to create or update the target.  A
-rule can also explain how and when to carry out an action.
-@xref{Rules, , Writing Rules}.
-
-A makefile may contain other text besides rules, but a simple makefile
-need only contain rules.  Rules may look somewhat more complicated
-than shown in this template, but all fit the pattern more or less.

-Here is a straightforward makefile that describes the way an
-executable file called @code{edit} depends on eight object files
-which, in turn, depend on eight C source and three header files.
-
-In this example, all the C files include @file{defs.h}, but only those
-defining editing commands include @file{command.h}, and only low
-level files that change the editor buffer include @file{buffer.h}.
-
-@example

-
-To use this makefile to delete the executable file and all the object
-files from the directory, type:
-
-@example
-make clean
-@end example
-
-In the example makefile, the targets include the executable file
-@samp{edit}, and the object files @samp{main.o} and @samp{kbd.o}.  The
-prerequisites are files such as @samp{main.c} and @samp{defs.h}.
-In fact, each @samp{.o} file is both a target and a prerequisite.
-Recipes include @w{@samp{cc -c main.c}} and @w{@samp{cc -c kbd.c}}.
-
-When a target is a file, it needs to be recompiled or relinked if any
-of its prerequisites change.  In addition, any prerequisites that are
-themselves automatically generated should be updated first.  In this
-example, @file{edit} depends on each of the eight object files; the
-object file @file{main.o} depends on the source file @file{main.c} and
-on the header file @file{defs.h}.
-
-A recipe may follow each line that contains a target and
-prerequisites.  These recipes say how to update the target file.  A
-tab character (or whatever character is specified by the
-@code{.RECIPEPREFIX} variable; @pxref{Special Variables}) must come at
-the beginning of every line in the recipe to distinguish recipes from
-other lines in the makefile.  (Bear in mind that @code{make} does not
-know anything about how the recipes work.  It is up to you to supply
-recipes that will update the target file properly.  All @code{make}
-does is execute the recipe you have specified when the target file
-needs to be updated.)@refill
-@cindex recipe
-
-The target @samp{clean} is not a file, but merely the name of an
-action.  Since you normally do not want to carry out the actions in
-this rule, @samp{clean} is not a prerequisite of any other rule.
-Consequently, @code{make} never does anything with it unless you tell
-it specifically.  Note that this rule not only is not a prerequisite,
-it also does not have any prerequisites, so the only purpose of the
-rule is to run the specified recipe.  Targets that do not refer to
-files but are just actions are called @dfn{phony targets}.

-@section How @code{make} Processes a Makefile
-@cindex processing a makefile
-@cindex makefile, how @code{make} processes
-
-By default, @code{make} starts with the first target (not targets whose
-names start with @samp{.}).  This is called the @dfn{default goal}.
-(@dfn{Goals} are the targets that @code{make} strives ultimately to
-update.    You can override this behavior using the command line
-(@pxref{Goals, , Arguments to Specify the Goals}) or with the
-@code{.DEFAULT_GOAL} special variable (@pxref{Special Variables, ,
-Other Special Variables}).
-@cindex default goal
-@cindex goal, default
-@cindex goal
-
-In the simple example of the previous section, the default goal is to
-update the executable program @file{edit}; therefore, we put that rule
-first.
-
-Thus, when you give the command:
-
-@example
-make
-@end example
-
-@noindent
-@code{make} reads the makefile in the current directory and begins by
-processing the first rule.  In the example, this rule is for relinking
-@file{edit}; but before @code{make} can fully process this rule, it
-must process the rules for the files that @file{edit} depends on,
-which in this case are the object files.  Each of these files is
-processed according to its own rule.  These rules say to update each
-@samp{.o} file by compiling its source file.  The recompilation must
-be done if the source file, or any of the header files named as
-prerequisites, is more recent than the object file, or if the object
-file does not exist.
-
-The other rules are processed because their targets appear as
-prerequisites of the goal.  If some other rule is not depended on by the
-goal (or anything it depends on, etc.), that rule is not processed,
-unless you tell @code{make} to do so (with a command such as
-@w{@code{make clean}}).
-
-Before recompiling an object file, @code{make} considers updating its
-prerequisites, the source file and header files.  This makefile does not
-specify anything to be done for them---the @samp{.c} and @samp{.h} files
-are not the targets of any rules---so @code{make} does nothing for these
-files.  But @code{make} would update automatically generated C programs,
-such as those made by Bison or Yacc, by their own rules at this time.
-
-After recompiling whichever object files need it, @code{make} decides
-whether to relink @file{edit}.  This must be done if the file
-@file{edit} does not exist, or if any of the object files are newer than
-it.  If an object file was just recompiled, it is now newer than
-@file{edit}, so @file{edit} is relinked.
-@cindex relinking
-
-Thus, if we change the file @file{insert.c} and run @code{make},
-@code{make} will compile that file to update @file{insert.o}, and then
-link @file{edit}.  If we change the file @file{command.h} and run
-@code{make}, @code{make} will recompile the object files @file{kbd.o},
-@file{command.o} and @file{files.o} and then link the file @file{edit}.

-In our example, we had to list all the object files twice in the rule for
-@file{edit} (repeated here):
-

-              insert.o search.o files.o utils.o

-                   insert.o search.o files.o utils.o
-@end group
-@end example
-
-@cindex @code{objects}
-Such duplication is error-prone; if a new object file is added to the
-system, we might add it to one list and forget the other.  We can eliminate
-the risk and simplify the makefile by using a variable.  @dfn{Variables}
-allow a text string to be defined once and substituted in multiple places
-later (@pxref{Using Variables, ,How to Use Variables}).
-
-@cindex @code{OBJECTS}
-@cindex @code{objs}
-@cindex @code{OBJS}
-@cindex @code{obj}
-@cindex @code{OBJ}
-It is standard practice for every makefile to have a variable named
-@code{objects}, @code{OBJECTS}, @code{objs}, @code{OBJS}, @code{obj},
-or @code{OBJ} which is a list of all object file names.  We would
-define such a variable @code{objects} with a line like this in the
-makefile:@refill
-
-@example
-@group
-objects = main.o kbd.o command.o display.o \
-          insert.o search.o files.o utils.o
-@end group
-@end example
-
-@noindent
-Then, each place we want to put a list of the object file names, we can
-substitute the variable's value by writing @samp{$(objects)}
-(@pxref{Using Variables, ,How to Use Variables}).
-
-Here is how the complete simple makefile looks when you use a variable
-for the object files:
-

-@cindex implicit rule, introduction to
-@cindex rule, implicit, introduction to
-
-It is not necessary to spell out the recipes for compiling the individual
-C source files, because @code{make} can figure them out: it has an
-@dfn{implicit rule} for updating a @samp{.o} file from a correspondingly
-named @samp{.c} file using a @samp{cc -c} command.  For example, it will
-use the recipe @samp{cc -c main.c -o main.o} to compile @file{main.c} into
-@file{main.o}.  We can therefore omit the recipes from the rules for the
-object files.  @xref{Implicit Rules, ,Using Implicit Rules}.@refill
-
-When a @samp{.c} file is used automatically in this way, it is also
-automatically added to the list of prerequisites.  We can therefore omit
-the @samp{.c} files from the prerequisites, provided we omit the recipe.
-
-Here is the entire example, with both of these changes, and a variable
-@code{objects} as suggested above:
-
-@example
-@group
-objects = main.o kbd.o command.o display.o \
-          insert.o search.o files.o utils.o
-
-edit : $(objects)

-utils.o : defs.h
-
-.PHONY : clean
-clean :
-        rm edit $(objects)
-@end group
-@end example
-
-@noindent
-This is how we would write the makefile in actual practice.  (The
-complications associated with @samp{clean} are described elsewhere.
-See @ref{Phony Targets}, and @ref{Errors, ,Errors in Recipes}.)
-
-Because implicit rules are so convenient, they are important.  You
-will see them used frequently.@refill
-
-@node Combine By Prerequisite, Cleanup, make Deduces, Introduction
-@section Another Style of Makefile
-@cindex combining rules by prerequisite
-
-When the objects of a makefile are created only by implicit rules, an
-alternative style of makefile is possible.  In this style of makefile,
-you group entries by their prerequisites instead of by their targets.
-Here is what one looks like:
-
-@example
-@group
-objects = main.o kbd.o command.o display.o \
-          insert.o search.o files.o utils.o
-
-edit : $(objects)
-        cc -o edit $(objects)
-
-$(objects) : defs.h
-kbd.o command.o files.o : command.h
-display.o insert.o search.o files.o : buffer.h
-@end group
-@end example
-
-@noindent
-Here @file{defs.h} is given as a prerequisite of all the object files;
-@file{command.h} and @file{buffer.h} are prerequisites of the specific
-object files listed for them.
-
-Whether this is better is a matter of taste: it is more compact, but some
-people dislike it because they find it clearer to put all the information
-about each target in one place.

-@node Cleanup,  , Combine By Prerequisite, Introduction
-@section Rules for Cleaning the Directory
-@cindex cleaning up
-@cindex removing, to clean up
-
-Compiling a program is not the only thing you might want to write rules
-for.  Makefiles commonly tell how to do a few other things besides
-compiling a program: for example, how to delete all the object files
-and executables so that the directory is @samp{clean}.
-
-@cindex @code{clean} target
-Here is how we
-could write a @code{make} rule for cleaning our example editor:
-
-@example
-@group
-clean:
-        rm edit $(objects)
-@end group
-@end example
-
-In practice, we might want to write the rule in a somewhat more
-complicated manner to handle unanticipated situations.  We would do this:
-
-@example
-@group
-.PHONY : clean
-clean :
-        -rm edit $(objects)
-@end group
-@end example
-
-@noindent
-This prevents @code{make} from getting confused by an actual file
-called @file{clean} and causes it to continue in spite of errors from
-@code{rm}.  (See @ref{Phony Targets}, and @ref{Errors, ,Errors in
-Recipes}.)
-
-@noindent
-A rule such as this should not be placed at the beginning of the
-makefile, because we do not want it to run by default!  Thus, in the
-example makefile, we want the rule for @code{edit}, which recompiles
-the editor, to remain the default goal.
-
-Since @code{clean} is not a prerequisite of @code{edit}, this rule will not
-run at all if we give the command @samp{make} with no arguments.  In
-order to make the rule run, we have to type @samp{make clean}.

-
-You cannot use comments within variable references or function calls:

-@cindex backslash (@code{\}), to quote newlines
-
-Makefiles use a ``line-based'' syntax in which the newline character
-is special and marks the end of a statement.  GNU @code{make} has no
-limit on the length of a statement line, up to the amount of memory in
-your computer.
-
-However, it is difficult to read lines which are too long to display
-without wrapping or scrolling.  So, you can format your makefiles for
-readability by adding newlines into the middle of a statement: you do
-this by escaping the internal newlines with a backslash (@code{\})
-character.  Where we need to make a distinction we will refer to
-``physical lines'' as a single line ending with a newline (regardless
-of whether it is escaped) and a ``logical line'' being a complete
-statement including all escaped newlines up to the first non-escaped
-newline.
-
-The way in which backslash/newline combinations are handled depends on
-whether the statement is a recipe line or a non-recipe line.  Handling
-of backslash/newline in a recipe line is discussed later
-(@pxref{Splitting Recipe Lines}).
-
-Outside of recipe lines, backslash/newlines are converted into a
-single space character.  Once that is done, all whitespace around the
-backslash/newline is condensed into a single space: this includes all
-whitespace preceding the backslash, all whitespace at the beginning of
-the line after the backslash/newline, and any consecutive
-backslash/newline combinations.
-
-If the @code{.POSIX} special target is defined then backslash/newline
-handling is modified slightly to conform to POSIX.2: first, whitespace
-preceding a backslash is not removed and second, consecutive
-backslash/newlines are not condensed.
-
-@subsubheading Splitting Without Adding Whitespace
-@cindex whitespace, avoiding on line split
-@cindex removing whitespace from split lines
-
-If you need to split a line but do @emph{not} want any whitespace
-added, you can utilize a subtle trick: replace your backslash/newline
-pairs with the three characters dollar sign/backslash/newline:
-
-@example
-var := one$\
-       word
-@end example
-
-After @code{make} removes the backslash/newline and condenses the
-following line into a single space, this is equivalent to:
-
-@example
-var := one$ word
-@end example
-
-Then @code{make} will perform variable expansion.  The variable
-reference @samp{$ } refers to a variable with the one-character name
-`` '' (space) which does not exist, and so expands to the empty
-string, giving a final assignment which is the equivalent of:

-Extra spaces are allowed and ignored at the beginning of the line, but
-the first character must not be a tab (or the value of
-@code{.RECIPEPREFIX})---if the line begins with a tab, it will be
-considered a recipe line.  Whitespace is required between
-@code{include} and the file names, and between file names; extra
-whitespace is ignored there and at the end of the directive.  A
-comment starting with @samp{#} is allowed at the end of the line.  If
-the file names contain any variable or function references, they are
-expanded.  @xref{Using Variables, ,How to Use Variables}.
-
-For example, if you have three @file{.mk} files, @file{a.mk},
-@file{b.mk}, and @file{c.mk}, and @code{$(bar)} expands to
-@code{bish bash}, then the following expression
-
-@example
-include foo *.mk $(bar)

-
-is equivalent to
-
-@example
-include foo a.mk b.mk c.mk bish bash

-
-When @code{make} processes an @code{include} directive, it suspends
-reading of the containing makefile and reads from each listed file in

-
-One occasion for using @code{include} directives is when several programs,
-handled by individual makefiles in various directories, need to use a

-(@pxref{Setting, ,Setting Variables}) or pattern rules
-(@pxref{Pattern Rules, ,Defining and Redefining Pattern Rules}).
-
-Another such occasion is when you want to generate prerequisites from
-source files automatically; the prerequisites can be put in a file that

-@file{/usr/gnu/include},
-@file{/usr/local/include}, @file{/usr/include}.
-
-If an included makefile cannot be found in any of these directories, a
-warning message is generated, but it is not an immediately fatal error;
-processing of the makefile containing the @code{include} continues.
-Once it has finished reading makefiles, @code{make} will try to remake
-any that are out of date or don't exist.
-@xref{Remaking Makefiles, ,How Makefiles Are Remade}.
-Only after it has tried to find a way to remake a makefile and failed,
-will @code{make} diagnose the missing makefile as a fatal error.
-
-If you want @code{make} to simply ignore a makefile which does not exist
-or cannot be remade, with no error message, use the @w{@code{-include}}

-@cindex updating makefiles
-@cindex remaking makefiles
-@cindex makefile, remaking of
-Sometimes makefiles can be remade from other files, such as RCS or SCCS
-files.  If a makefile can be remade from other files, you probably want
-@code{make} to get an up-to-date version of the makefile to read in.
-
-To this end, after reading in all makefiles @code{make} will consider
-each as a goal target and attempt to update it.  If a makefile has a
-rule which says how to update it (found either in that very makefile or
-in another one) or if an implicit rule applies to it (@pxref{Implicit
-Rules, ,Using Implicit Rules}), it will be updated if necessary.  After
-all makefiles have been checked, if any have actually been changed,
-@code{make} starts with a clean slate and reads all the makefiles over
-again.  (It will also attempt to update each of them over again, but
-normally this will not change them again, since they are already up to
-date.)  Each restart will cause the special variable
-@code{MAKE_RESTARTS} to be updated (@pxref{Special Variables}).@refill
-
-If you know that one or more of your makefiles cannot be remade and
-you want to keep @code{make} from performing an implicit rule search
-on them, perhaps for efficiency reasons, you can use any normal method
-of preventing implicit rule look-up to do so.  For example, you can
-write an explicit rule with the makefile as the target, and an empty
-recipe (@pxref{Empty Recipes, ,Using Empty Recipes}).
-
-If the makefiles specify a double-colon rule to remake a file with
-a recipe but no prerequisites, that file will always be remade
-(@pxref{Double-Colon}).  In the case of makefiles, a makefile that has a
-double-colon rule with a recipe but no prerequisites will be remade every
-time @code{make} is run, and then again after @code{make} starts over
-and reads the makefiles in again.  This would cause an infinite loop:
-@code{make} would constantly remake the makefile, and never do anything
-else.  So, to avoid this, @code{make} will @strong{not} attempt to
-remake makefiles which are specified as targets of a double-colon rule
-with a recipe but no prerequisites.@refill
-
-If you do not specify any makefiles to be read with @samp{-f} or
-@samp{--file} options, @code{make} will try the default makefile names;
-@pxref{Makefile Names, ,What Name to Give Your Makefile}.  Unlike
-makefiles explicitly requested with @samp{-f} or @samp{--file} options,
-@code{make} is not certain that these makefiles should exist.  However,
-if a default makefile does not exist but can be created by running
-@code{make} rules, you probably want the rules to be run so that the
-makefile can be used.
-
-Therefore, if none of the default makefiles exists, @code{make} will try
-to make each of them in the same order in which they are searched for
-(@pxref{Makefile Names, ,What Name to Give Your Makefile})
-until it succeeds in making one, or it runs out of names to try.  Note
-that it is not an error if @code{make} cannot find or make any makefile;
-a makefile is not always necessary.@refill
-
-When you use the @samp{-t} or @samp{--touch} option
-(@pxref{Instead of Execution, ,Instead of Executing Recipes}),
-you would not want to use an out-of-date makefile to decide which
-targets to touch.  So the @samp{-t} option has no effect on updating
-makefiles; they are really updated even if @samp{-t} is specified.
-Likewise, @samp{-q} (or @samp{--question}) and @samp{-n} (or
-@samp{--just-print}) do not prevent updating of makefiles, because an
-out-of-date makefile would result in the wrong output for other targets.
-Thus, @samp{make -f mfile -n foo} will update @file{mfile}, read it in,
-and then print the recipe to update @file{foo} and its prerequisites
-without running it.  The recipe printed for @file{foo} will be the one
-specified in the updated contents of @file{mfile}.
-
-However, on occasion you might actually wish to prevent updating of even
-the makefiles.  You can do this by specifying the makefiles as goals in
-the command line as well as specifying them as makefiles.  When the
-makefile name is specified explicitly as a goal, the options @samp{-t}
-and so on do apply to them.
-
-Thus, @samp{make -f mfile -n mfile foo} would read the makefile
-@file{mfile}, print the recipe needed to update it without actually
-running it, and then print the recipe needed to update @file{foo}
-without running that.  The recipe for @file{foo} will be the one
-specified by the existing contents of @file{mfile}.

-@cindex overriding makefiles
-@cindex makefile, overriding
-Sometimes it is useful to have a makefile that is mostly just like
-another makefile.  You can often use the @samp{include} directive to
-include one in the other, and add more targets or variable definitions.
-However, it is invalid for two makefiles to give different recipes for
-the same target.  But there is another way.
-
-@cindex match-anything rule, used to override
-In the containing makefile (the one that wants to include the other),
-you can use a match-anything pattern rule to say that to remake any
-target that cannot be made from the information in the containing
-makefile, @code{make} should look in another makefile.
-@xref{Pattern Rules}, for more information on pattern rules.
-
-For example, if you have a makefile called @file{Makefile} that says how
-to make the target @samp{foo} (and other targets), you can write a
-makefile called @file{GNUmakefile} that contains:
-
-@example
-foo:
-        frobnicate > foo
-
-%: force
-        @@$(MAKE) -f Makefile $@@
-force: ;
-@end example
-
-If you say @samp{make foo}, @code{make} will find @file{GNUmakefile},
-read it, and see that to make @file{foo}, it needs to run the recipe
-@samp{frobnicate > foo}.  If you say @samp{make bar}, @code{make} will
-find no way to make @file{bar} in @file{GNUmakefile}, so it will use the
-recipe from the pattern rule: @samp{make -f Makefile bar}.  If
-@file{Makefile} provides a rule for updating @file{bar}, @code{make}
-will apply the rule.  And likewise for any other target that
-@file{GNUmakefile} does not say how to make.
-
-The way this works is that the pattern rule has a pattern of just
-@samp{%}, so it matches any target whatever.  The rule specifies a
-prerequisite @file{force}, to guarantee that the recipe will be run even
-if the target file already exists.  We give the @file{force} target an
-empty recipe to prevent @code{make} from searching for an implicit rule to
-build it---otherwise it would apply the same match-anything rule to
-@file{force} itself and create a prerequisite loop!

-@section How @code{make} Reads a Makefile
-@cindex reading makefiles
-@cindex makefile, reading
-
-GNU @code{make} does its work in two distinct phases.  During the
-first phase it reads all the makefiles, included makefiles, etc. and
-internalizes all the variables and their values and implicit and
-explicit rules, and builds a dependency graph of all the targets and
-their prerequisites.  During the second phase, @code{make} uses this
-internalized data to determine which targets need to be updated and
-run the recipes necessary to update them.
-
-It's important to understand this two-phase approach because it has a
-direct impact on how variable and function expansion happens; this is
-often a source of some confusion when writing makefiles.  Below is a
-summary of the different constructs that can be found in a makefile,
-and the phase in which expansion happens for each part of the
-construct.
-
-We say that expansion is @dfn{immediate} if it happens during the
-first phase: @code{make} will expand that part of the construct as the
-makefile is parsed.  We say that expansion is @dfn{deferred} if it is
-not immediate.  Expansion of a deferred construct part is delayed
-until the expansion is used: either when it is referenced in an
-immediate context, or when it is needed during the second phase.
-
-You may not be familiar with some of these constructs yet.  You can
-reference this section as you become familiar with them, in later
-chapters.

-@var{immediate} = @var{deferred}
-@var{immediate} ?= @var{deferred}

-
-For the append operator @samp{+=}, the right-hand side is considered
-immediate if the variable was previously set as a simple variable
-(@samp{:=} or @samp{::=}), and deferred otherwise.
-
-For the shell assignment operator @samp{!=}, the right-hand side is
-evaluated immediately and handed to the shell.  The result is stored
-in the variable named on the left, and that variable becomes a simple
-variable (and will thus be re-evaluated on each reference).
-
-@subheading Conditional Directives
-@cindex ifdef, expansion
-@cindex ifeq, expansion
-@cindex ifndef, expansion
-@cindex ifneq, expansion
-
-Conditional directives are parsed immediately.  This means, for
-example, that automatic variables cannot be used in conditional
-directives, as automatic variables are not set until the recipe for
-that rule is invoked.  If you need to use automatic variables in a
-conditional directive you @emph{must} move the condition into the

-
-@subheading Rule Definition
-@cindex target, expansion
-@cindex prerequisite, expansion
-@cindex implicit rule, expansion

-
-@example
-@var{immediate} : @var{immediate} ; @var{deferred}
-        @var{deferred}
-@end example
-
-That is, the target and prerequisite sections are expanded
-immediately, and the recipe used to build the target is always
-deferred.  This is true for explicit rules, pattern rules, suffix
-rules, static pattern rules, and simple prerequisite definitions.

-@section How Makefiles Are Parsed
-@cindex parsing makefiles
-@cindex makefiles, parsing
-
-GNU @code{make} parses makefiles line-by-line.  Parsing proceeds using
-the following steps:
-
-@enumerate
-@item
-Read in a full logical line, including backslash-escaped lines
-(@pxref{Splitting Lines, , Splitting Long Lines}).
-
-@item
-Remove comments (@pxref{Makefile Contents, , What Makefiles Contain}).
-
-@item
-If the line begins with the recipe prefix character and we are in a
-rule context, add the line to the current recipe and read the next
-line (@pxref{Recipe Syntax}).
-
-@item
-Expand elements of the line which appear in an @emph{immediate}
-expansion context (@pxref{Reading Makefiles, , How @code{make} Reads a
-Makefile}).@refill
-
-@item
-Scan the line for a separator character, such as @samp{:} or @samp{=},
-to determine whether the line is a macro assignment or a rule
-(@pxref{Recipe Syntax}).
-
-@item
-Internalize the resulting operation and read the next line.
-@end enumerate
-
-An important consequence of this is that a macro can expand to an
-entire rule, @emph{if it is one line long}.  This will work:
-
-@example
-myrule = target : ; echo built
-
-$(myrule)
-@end example
-
-However, this will not work because @code{make} does not re-split lines
-after it has expanded them:
-
-@example
-define myrule
-target:
-        echo built
-endef
-
-$(myrule)
-@end example
-
-The above makefile results in the definition of a target @samp{target}
-with prerequisites @samp{echo} and @samp{built}, as if the makefile
-contained @code{target: echo built}, rather than a rule with a recipe.
-Newlines still present in a line after expansion is complete are
-ignored as normal whitespace.
-
-In order to properly expand a multi-line macro you must use the
-@code{eval} function: this causes the @code{make} parser to be run on
-the results of the expanded macro (@pxref{Eval Function}).

-Previously we learned that GNU @code{make} works in two distinct
-phases: a read-in phase and a target-update phase (@pxref{Reading

-the ability to enable a @emph{second expansion} of the prerequisites
-(only) for some or all targets defined in the makefile.  In order for
-this second expansion to occur, the special target
-@code{.SECONDEXPANSION} must be defined before the first prerequisite
-list that makes use of this feature.
-
-If that special target is defined then in between the two phases
-mentioned above, right at the end of the read-in phase, all the
-prerequisites of the targets defined after the special target are
-expanded a @emph{second time}.  In most circumstances this secondary
-expansion will have no effect, since all variable and function
-references will have been expanded during the initial parsing of the
-makefiles.  In order to take advantage of the secondary expansion
-phase of the parser, then, it's necessary to @emph{escape} the
-variable or function reference in the makefile.  In this case the
-first expansion merely un-escapes the reference but doesn't expand it,
-and expansion is left to the secondary expansion phase.  For example,
-consider this makefile:
-
-@example
-.SECONDEXPANSION:
-ONEVAR = onefile
-TWOVAR = twofile
-myfile: $(ONEVAR) $$(TWOVAR)
-@end example
-
-After the first expansion phase the prerequisites list of the
-@file{myfile} target will be @code{onefile} and @code{$(TWOVAR)}; the
-first (unescaped) variable reference to @var{ONEVAR} is expanded,
-while the second (escaped) variable reference is simply unescaped,
-without being recognized as a variable reference.  Now during the
-secondary expansion the first word is expanded again but since it
-contains no variable or function references it remains the value
-@file{onefile}, while the second word is now a normal reference to the
-variable @var{TWOVAR}, which is expanded to the value @file{twofile}.
-The final result is that there are two prerequisites, @file{onefile}
-and @file{twofile}.
-
-Obviously, this is not a very interesting case since the same result
-could more easily have been achieved simply by having both variables
-appear, unescaped, in the prerequisites list.  One difference becomes
-apparent if the variables are reset; consider this example:
-
-@example
-.SECONDEXPANSION:
-AVAR = top
-onefile: $(AVAR)
-twofile: $$(AVAR)
-AVAR = bottom
-@end example
-
-Here the prerequisite of @file{onefile} will be expanded immediately,
-and resolve to the value @file{top}, while the prerequisite of
-@file{twofile} will not be full expanded until the secondary expansion
-and yield a value of @file{bottom}.
-
-This is marginally more exciting, but the true power of this feature
-only becomes apparent when you discover that secondary expansions
-always take place within the scope of the automatic variables for that
-target.  This means that you can use variables such as @code{$@@},
-@code{$*}, etc. during the second expansion and they will have their
-expected values, just as in the recipe.  All you have to do is defer
-the expansion by escaping the @code{$}.  Also, secondary expansion
-occurs for both explicit and implicit (pattern) rules.  Knowing this,
-the possible uses for this feature increase dramatically.  For
-example:
-
-@example
-.SECONDEXPANSION:
-main_OBJS := main.o try.o test.o
-lib_OBJS := lib.o api.o
-
-main lib: $$($$@@_OBJS)
-@end example
-
-Here, after the initial expansion the prerequisites of both the
-@file{main} and @file{lib} targets will be @code{$($@@_OBJS)}.  During
-the secondary expansion, the @code{$@@} variable is set to the name of
-the target and so the expansion for the @file{main} target will yield
-@code{$(main_OBJS)}, or @code{main.o try.o test.o}, while the
-secondary expansion for the @file{lib} target will yield
-@code{$(lib_OBJS)}, or @code{lib.o api.o}.
-
-You can also mix in functions here, as long as they are properly escaped:
-
-@example
-main_SRCS := main.c try.c test.c
-lib_SRCS := lib.c api.c
-
-.SECONDEXPANSION:
-main lib: $$(patsubst %.c,%.o,$$($$@@_SRCS))
-@end example
-
-This version allows users to specify source files rather than object
-files, but gives the same resulting prerequisites list as the previous
-example.
-
-Evaluation of automatic variables during the secondary expansion
-phase, especially of the target name variable @code{$$@@}, behaves
-similarly to evaluation within recipes.  However, there are some
-subtle differences and ``corner cases'' which come into play for the
-different types of rule definitions that @code{make} understands.  The
-subtleties of using the different automatic variables are described
-below.
-
-@subheading Secondary Expansion of Explicit Rules
-@cindex secondary expansion and explicit rules
-@cindex explicit rules, secondary expansion of
-
-During the secondary expansion of explicit rules, @code{$$@@} and
-@code{$$%} evaluate, respectively, to the file name of the target and,
-when the target is an archive member, the target member name.  The
-@code{$$<} variable evaluates to the first prerequisite in the first
-rule for this target.  @code{$$^} and @code{$$+} evaluate to the list
-of all prerequisites of rules @emph{that have already appeared} for
-the same target (@code{$$+} with repetitions and @code{$$^}
-without).  The following example will help illustrate these behaviors:
-
-@example
-.SECONDEXPANSION:
-
-foo: foo.1 bar.1 $$< $$^ $$+    # line #1
-
-foo: foo.2 bar.2 $$< $$^ $$+    # line #2
-
-foo: foo.3 bar.3 $$< $$^ $$+    # line #3
-@end example
-
-In the first prerequisite list, all three variables (@code{$$<},
-@code{$$^}, and @code{$$+}) expand to the empty string.  In the
-second, they will have values @code{foo.1}, @code{foo.1 bar.1}, and
-@code{foo.1 bar.1} respectively.  In the third they will have values
-@code{foo.1}, @code{foo.1 bar.1 foo.2 bar.2}, and @code{foo.1 bar.1
-foo.2 bar.2 foo.1 foo.1 bar.1 foo.1 bar.1} respectively.
-
-Rules undergo secondary expansion in makefile order, except that
-the rule with the recipe is always evaluated last.
-
-The variables @code{$$?} and @code{$$*} are not available and expand
-to the empty string.
-
-@subheading Secondary Expansion of Static Pattern Rules
-@cindex secondary expansion and static pattern rules
-@cindex static pattern rules, secondary expansion of
-
-Rules for secondary expansion of static pattern rules are identical to
-those for explicit rules, above, with one exception: for static
-pattern rules the @code{$$*} variable is set to the pattern stem.  As
-with explicit rules, @code{$$?} is not available and expands to the
-empty string.
-
-@subheading Secondary Expansion of Implicit Rules
-@cindex secondary expansion and implicit rules
-@cindex implicit rules, secondary expansion of
-
-As @code{make} searches for an implicit rule, it substitutes the stem
-and then performs secondary expansion for every rule with a matching
-target pattern.  The value of the automatic variables is derived in
-the same fashion as for static pattern rules.  As an example:
-
-@example
-.SECONDEXPANSION:
-
-foo: bar
-
-foo foz: fo%: bo%
-
-%oo: $$< $$^ $$+ $$*
-@end example
-
-When the implicit rule is tried for target @file{foo}, @code{$$<}
-expands to @file{bar}, @code{$$^} expands to @file{bar boo},
-@code{$$+} also expands to @file{bar boo}, and @code{$$*} expands to
-@file{f}.
-
-Note that the directory prefix (D), as described in @ref{Implicit Rule
-Search, ,Implicit Rule Search Algorithm}, is appended (after
-expansion) to all the patterns in the prerequisites list.  As an
-example:@refill
-
-@example
-.SECONDEXPANSION:
-
-/tmp/foo.o:
-
-%.o: $$(addsuffix /%.c,foo bar) foo.h
-        @@echo $^
-@end example
-
-The prerequisite list printed, after the secondary expansion and
-directory prefix reconstruction, will be @file{/tmp/foo/foo.c
-/tmp/bar/foo.c foo.h}.  If you are not interested in this
-reconstruction, you can use @code{$$*} instead of @code{%} in the
-prerequisites list.

-@cindex types of prerequisites
-
-@cindex prerequisites, normal
-@cindex normal prerequisites
-@cindex prerequisites, order-only
-@cindex order-only prerequisites
-There are actually two different types of prerequisites understood by
-GNU @code{make}: normal prerequisites such as described in the
-previous section, and @dfn{order-only} prerequisites.  A normal
-prerequisite makes two statements: first, it imposes an order in which
-recipes will be invoked: the recipes for all prerequisites of a target
-will be completed before the recipe for the target is run.  Second, it
-imposes a dependency relationship: if any prerequisite is newer than
-the target, then the target is considered out-of-date and must be
-rebuilt.
-
-Normally, this is exactly what you want: if a target's prerequisite is
-updated, then the target should also be updated.
-
-Occasionally, however, you have a situation where you want to impose a
-specific ordering on the rules to be invoked @emph{without} forcing
-the target to be updated if one of those rules is executed.  In that
-case, you want to define @dfn{order-only} prerequisites.  Order-only
-prerequisites can be specified by placing a pipe symbol (@code{|})
-in the prerequisites list: any prerequisites to the left of the pipe
-symbol are normal; any prerequisites to the right are order-only:
-
-@example
-@var{targets} : @var{normal-prerequisites} | @var{order-only-prerequisites}
-@end example
-
-The normal prerequisites section may of course be empty.  Also, you
-may still declare multiple lines of prerequisites for the same target:
-they are appended appropriately (normal prerequisites are appended to
-the list of normal prerequisites; order-only prerequisites are
-appended to the list of order-only prerequisites).  Note that if you
-declare the same file to be both a normal and an order-only
-prerequisite, the normal prerequisite takes precedence (since they
-have a strict superset of the behavior of an order-only prerequisite).
-
-Consider an example where your targets are to be placed in a separate
-directory, and that directory might not exist before @code{make} is
-run.  In this situation, you want the directory to be created before
-any targets are placed into it but, because the timestamps on
-directories change whenever a file is added, removed, or renamed, we
-certainly don't want to rebuild all the targets whenever the
-directory's timestamp changes.  One way to manage this is with
-order-only prerequisites: make the directory an order-only
-prerequisite on all the targets:
-
-@example
-OBJDIR := objdir
-OBJS := $(addprefix $(OBJDIR)/,foo.o bar.o baz.o)
-
-$(OBJDIR)/%.o : %.c
-        $(COMPILE.c) $(OUTPUT_OPTION) $<
-
-all: $(OBJS)
-
-$(OBJS): | $(OBJDIR)
-
-$(OBJDIR):
-        mkdir $(OBJDIR)
-@end example
-
-Now the rule to create the @file{objdir} directory will be run, if
-needed, before any @samp{.o} is built, but no @samp{.o} will be built
-because the @file{objdir} directory timestamp changed.

-If the @samp{~} is followed by a word, the string represents the home
-directory of the user named by that word.  For example @file{~john/bin}
-expands to @file{/home/john/bin}.  On systems which don't have a home

-@subsection Wildcard Examples
-
-Wildcards can be used in the recipe of a rule, where they are expanded
-by the shell.  For example, here is a rule to delete all the object files:
-
-@example
-@group
-clean:
-        rm -f *.o
-@end group
-@end example
-@cindex @code{rm} (shell command)
-
-Wildcards are also useful in the prerequisites of a rule.  With the
-following rule in the makefile, @samp{make print} will print all the
-@samp{.c} files that have changed since the last time you printed them:
-
-@example
-print: *.c
-        lpr -p $?
-        touch print
-@end example
-
-@cindex @code{print} target
-@cindex @code{lpr} (shell command)
-@cindex @code{touch} (shell command)
-@noindent
-This rule uses @file{print} as an empty target file; see @ref{Empty
-Targets, ,Empty Target Files to Record Events}.  (The automatic variable
-@samp{$?} is used to print only those files that have changed; see
-@ref{Automatic Variables}.)@refill
-
-Wildcard expansion does not happen when you define a variable.  Thus, if
-you write this:
-
-@example
-objects = *.o
-@end example
-
-@noindent
-then the value of the variable @code{objects} is the actual string
-@samp{*.o}.  However, if you use the value of @code{objects} in a
-target or prerequisite, wildcard expansion will take place there.  If
-you use the value of @code{objects} in a recipe, the shell may perform
-wildcard expansion when the recipe runs.  To set @code{objects} to the
-expansion, instead use:
-
-@example
-objects := $(wildcard *.o)

-@subsection Pitfalls of Using Wildcards
-@cindex wildcard pitfalls
-@cindex pitfalls of wildcards
-@cindex mistakes with wildcards
-@cindex errors with wildcards
-@cindex problems with wildcards
-
-Now here is an example of a naive way of using wildcard expansion, that
-does not do what you would intend.  Suppose you would like to say that the
-executable file @file{foo} is made from all the object files in the
-directory, and you write this:
-
-@example
-objects = *.o
-
-foo : $(objects)
-        cc -o foo $(CFLAGS) $(objects)
-@end example
-
-@noindent
-The value of @code{objects} is the actual string @samp{*.o}.  Wildcard
-expansion happens in the rule for @file{foo}, so that each @emph{existing}
-@samp{.o} file becomes a prerequisite of @file{foo} and will be recompiled if
-necessary.
-
-But what if you delete all the @samp{.o} files?  When a wildcard matches
-no files, it is left as it is, so then @file{foo} will depend on the
-oddly-named file @file{*.o}.  Since no such file is likely to exist,
-@code{make} will give you an error saying it cannot figure out how to
-make @file{*.o}.  This is not what you want!
-
-Actually it is possible to obtain the desired result with wildcard
-expansion, but you need more sophisticated techniques, including the
-@code{wildcard} function and string substitution.

-  c:\foo\bar\baz.c
-@end example
-
-This is equivalent to the Unix-style @file{c:/foo/bar/baz.c} (the
-@file{c:} part is the so-called drive letter).  When @code{make} runs on
-these systems, it supports backslashes as well as the Unix-style forward
-slashes in pathnames.  However, this support does @emph{not} include the
-wildcard expansion, where backslash is a quote character.  Therefore,
-you @emph{must} use Unix-style slashes in these cases.

-
-@node Wildcard Function,  , Wildcard Pitfall, Wildcards
-@subsection The Function @code{wildcard}
-@findex wildcard
-
-Wildcard expansion happens automatically in rules.  But wildcard expansion
-does not normally take place when a variable is set, or inside the
-arguments of a function.  If you want to do wildcard expansion in such
-places, you need to use the @code{wildcard} function, like this:
-
-@example
-$(wildcard @var{pattern}@dots{})
-@end example
-
-@noindent
-This string, used anywhere in a makefile, is replaced by a
-space-separated list of names of existing files that match one of the
-given file name patterns.  If no existing file name matches a pattern,
-then that pattern is omitted from the output of the @code{wildcard}
-function.  Note that this is different from how unmatched wildcards
-behave in rules, where they are used verbatim rather than ignored
-(@pxref{Wildcard Pitfall}).
-
-One use of the @code{wildcard} function is to get a list of all the C source
-files in a directory, like this:
-
-@example
-$(wildcard *.c)
-@end example
-
-We can change the list of C source files into a list of object files by
-replacing the @samp{.c} suffix with @samp{.o} in the result, like this:
-
-@example
-$(patsubst %.c,%.o,$(wildcard *.c))
-@end example
-
-@noindent
-(Here we have used another function, @code{patsubst}.
-@xref{Text Functions, ,Functions for String Substitution and Analysis}.)@refill
-
-Thus, a makefile to compile all C source files in the directory and then
-link them together could be written as follows:
-
-@example
-objects := $(patsubst %.c,%.o,$(wildcard *.c))
-
-foo : $(objects)
-        cc -o foo $(objects)
-@end example
-
-@noindent

-@subsection @code{VPATH}: Search Path for All Prerequisites
-@vindex VPATH
-
-The value of the @code{make} variable @code{VPATH} specifies a list of
-directories that @code{make} should search.  Most often, the
-directories are expected to contain prerequisite files that are not in the
-current directory; however, @code{make} uses @code{VPATH} as a search
-list for both prerequisites and targets of rules.
-
-Thus, if a file that is listed as a target or prerequisite does not exist
-in the current directory, @code{make} searches the directories listed in
-@code{VPATH} for a file with that name.  If a file is found in one of
-them, that file may become the prerequisite (see below).  Rules may then
-specify the names of files in the prerequisite list as if they all
-existed in the current directory.  @xref{Recipes/Search, ,Writing Recipes with Directory Search}.
-
-In the @code{VPATH} variable, directory names are separated by colons or
-blanks.  The order in which directories are listed is the order followed
-by @code{make} in its search.  (On MS-DOS and MS-Windows, semi-colons
-are used as separators of directory names in @code{VPATH}, since the
-colon can be used in the pathname itself, after the drive letter.)
-
-For example,
-
-@example
-VPATH = src:../headers
-@end example
-
-@noindent
-specifies a path containing two directories, @file{src} and
-@file{../headers}, which @code{make} searches in that order.
-
-With this value of @code{VPATH}, the following rule,
-
-@example
-foo.o : foo.c
-@end example
-
-@noindent
-is interpreted as if it were written like this:
-
-@example
-foo.o : src/foo.c
-@end example
-
-@noindent
-assuming the file @file{foo.c} does not exist in the current directory but
-is found in the directory @file{src}.
-
-@node Selective Search, Search Algorithm, General Search, Directory Search
-@subsection The @code{vpath} Directive
-@findex vpath
-
-Similar to the @code{VPATH} variable, but more selective, is the
-@code{vpath} directive (note lower case), which allows you to specify a
-search path for a particular class of file names: those that match a
-particular pattern.  Thus you can supply certain search directories for
-one class of file names and other directories (or none) for other file
-names.
-
-There are three forms of the @code{vpath} directive:
-
-@table @code
-@item vpath @var{pattern} @var{directories}
-Specify the search path @var{directories} for file names that match
-@var{pattern}.
-
-The search path, @var{directories}, is a list of directories to be
-searched, separated by colons (semi-colons on MS-DOS and MS-Windows) or
-blanks, just like the search path used in the @code{VPATH} variable.
-
-@item vpath @var{pattern}
-Clear out the search path associated with @var{pattern}.
-
-@c Extra blank line makes sure this gets two lines.
-@item vpath
-
-Clear all search paths previously specified with @code{vpath} directives.
-@end table
-
-A @code{vpath} pattern is a string containing a @samp{%} character.  The
-string must match the file name of a prerequisite that is being searched
-for, the @samp{%} character matching any sequence of zero or more
-characters (as in pattern rules; @pxref{Pattern Rules, ,Defining and
-Redefining Pattern Rules}).  For example, @code{%.h} matches files that
-end in @code{.h}.  (If there is no @samp{%}, the pattern must match the
-prerequisite exactly, which is not useful very often.)
-
-@cindex @code{%}, quoting in @code{vpath}
-@cindex @code{%}, quoting with @code{\} (backslash)
-@cindex @code{\} (backslash), to quote @code{%}
-@cindex backslash (@code{\}), to quote @code{%}
-@cindex quoting @code{%}, in @code{vpath}
-@samp{%} characters in a @code{vpath} directive's pattern can be quoted
-with preceding backslashes (@samp{\}).  Backslashes that would otherwise
-quote @samp{%} characters can be quoted with more backslashes.
-Backslashes that quote @samp{%} characters or other backslashes are
-removed from the pattern before it is compared to file names.  Backslashes
-that are not in danger of quoting @samp{%} characters go unmolested.@refill
-
-When a prerequisite fails to exist in the current directory, if the
-@var{pattern} in a @code{vpath} directive matches the name of the
-prerequisite file, then the @var{directories} in that directive are searched
-just like (and before) the directories in the @code{VPATH} variable.
-
-For example,
-
-@example
-vpath %.h ../headers
-@end example
-
-@noindent
-tells @code{make} to look for any prerequisite whose name ends in @file{.h}
-in the directory @file{../headers} if the file is not found in the current
-directory.
-
-If several @code{vpath} patterns match the prerequisite file's name, then
-@code{make} processes each matching @code{vpath} directive one by one,
-searching all the directories mentioned in each directive.  @code{make}
-handles multiple @code{vpath} directives in the order in which they
-appear in the makefile; multiple directives with the same pattern are
-independent of each other.
-
-@need 750
-Thus,
-
-@example
-@group
-vpath %.c foo
-vpath %   blish
-vpath %.c bar
-@end group
-@end example
-
-@noindent
-will look for a file ending in @samp{.c} in @file{foo}, then
-@file{blish}, then @file{bar}, while
-
-@example
-@group
-vpath %.c foo:bar
-vpath %   blish

-will look for a file ending in @samp{.c} in @file{foo}, then

-@node Search Algorithm, Recipes/Search, Selective Search, Directory Search
-@subsection How Directory Searches are Performed
-@cindex algorithm for directory search
-@cindex directory search algorithm
-
-When a prerequisite is found through directory search, regardless of type
-(general or selective), the pathname located may not be the one that
-@code{make} actually provides you in the prerequisite list.  Sometimes
-the path discovered through directory search is thrown away.
-
-The algorithm @code{make} uses to decide whether to keep or abandon a
-path found via directory search is as follows:
-
-@enumerate
-@item
-If a target file does not exist at the path specified in the makefile,
-directory search is performed.
-
-@item
-If the directory search is successful, that path is kept and this file
-is tentatively stored as the target.
-
-@item
-All prerequisites of this target are examined using this same method.
-
-@item
-After processing the prerequisites, the target may or may not need to be
-rebuilt:
-
-@enumerate a
-@item
-If the target does @emph{not} need to be rebuilt, the path to the file
-found during directory search is used for any prerequisite lists which
-contain this target.  In short, if @code{make} doesn't need to rebuild
-the target then you use the path found via directory search.
-
-@item
-If the target @emph{does} need to be rebuilt (is out-of-date), the
-pathname found during directory search is @emph{thrown away}, and the
-target is rebuilt using the file name specified in the makefile.  In
-short, if @code{make} must rebuild, then the target is rebuilt locally,
-not in the directory found via directory search.
-@end enumerate
-@end enumerate
-
-This algorithm may seem complex, but in practice it is quite often
-exactly what you want.
-
-@cindex traditional directory search (GPATH)
-@cindex directory search, traditional (GPATH)
-Other versions of @code{make} use a simpler algorithm: if the file does
-not exist, and it is found via directory search, then that pathname is
-always used whether or not the target needs to be built.  Thus, if the
-target is rebuilt it is created at the pathname discovered during
-directory search.
-
-@vindex GPATH
-If, in fact, this is the behavior you want for some or all of your
-directories, you can use the @code{GPATH} variable to indicate this to
-@code{make}.
-
-@code{GPATH} has the same syntax and format as @code{VPATH} (that is, a
-space- or colon-delimited list of pathnames).  If an out-of-date target
-is found by directory search in a directory that also appears in
-@code{GPATH}, then that pathname is not thrown away.  The target is
-rebuilt using the expanded path.

-@node Recipes/Search, Implicit/Search, Search Algorithm, Directory Search
-@subsection Writing Recipes with Directory Search
-@cindex recipes, and directory search
-@cindex directory search (@code{VPATH}), and recipes
-
-When a prerequisite is found in another directory through directory search,
-this cannot change the recipe of the rule; they will execute as written.
-Therefore, you must write the recipe with care so that it will look for
-the prerequisite in the directory where @code{make} finds it.
-
-This is done with the @dfn{automatic variables} such as @samp{$^}
-(@pxref{Automatic Variables}).
-For instance, the value of @samp{$^} is a
-list of all the prerequisites of the rule, including the names of
-the directories in which they were found, and the value of
-@samp{$@@} is the target.  Thus:@refill
-
-@example
-foo.o : foo.c
-        cc -c $(CFLAGS) $^ -o $@@
-@end example
-
-@noindent
-(The variable @code{CFLAGS} exists so you can specify flags for C
-compilation by implicit rules; we use it here for consistency so it will
-affect all C compilations uniformly;
-@pxref{Implicit Variables, ,Variables Used by Implicit Rules}.)
-
-Often the prerequisites include header files as well, which you do not
-want to mention in the recipe.  The automatic variable @samp{$<} is
-just the first prerequisite:
-
-@example
-VPATH = src:../headers
-foo.o : foo.c defs.h hack.h
-        cc -c $(CFLAGS) $< -o $@@

-
-The search through the directories specified in @code{VPATH} or with
-@code{vpath} also happens during consideration of implicit rules
-(@pxref{Implicit Rules, ,Using Implicit Rules}).
-
-For example, when a file @file{foo.o} has no explicit rule, @code{make}
-considers implicit rules, such as the built-in rule to compile
-@file{foo.c} if that file exists.  If such a file is lacking in the
-current directory, the appropriate directories are searched for it.  If
-@file{foo.c} exists (or is mentioned in the makefile) in any of the
-directories, the implicit rule for C compilation is applied.
-
-The recipes of implicit rules normally use automatic variables as a
-matter of necessity; consequently they will use the file names found by
-directory search with no extra effort.

-@cindex link libraries, patterns matching
-@cindex @code{.LIBPATTERNS}, and link libraries
-@vindex .LIBPATTERNS
-
-Directory search applies in a special way to libraries used with the
-linker.  This special feature comes into play when you write a prerequisite
-whose name is of the form @samp{-l@var{name}}.  (You can tell something
-strange is going on here because the prerequisite is normally the name of a
-file, and the @emph{file name} of a library generally looks like
-@file{lib@var{name}.a}, not like @samp{-l@var{name}}.)@refill
-
-When a prerequisite's name has the form @samp{-l@var{name}}, @code{make}
-handles it specially by searching for the file @file{lib@var{name}.so},
-and, if it is not found, for the file @file{lib@var{name}.a} in the current
-directory, in directories specified by matching @code{vpath}
-search paths and the @code{VPATH} search path, and then in the
-directories @file{/lib}, @file{/usr/lib}, and @file{@var{prefix}/lib}
-(normally @file{/usr/local/lib}, but MS-DOS/MS-Windows versions of
-@code{make} behave as if @var{prefix} is defined to be the root of the
-DJGPP installation tree).
-
-For example, if there is a @file{/usr/lib/libcurses.a} library on your
-system (and no @file{/usr/lib/libcurses.so} file), then
-
-@example
-@group
-foo : foo.c -lcurses
-        cc $^ -o $@@
-@end group
-@end example
-
-@noindent
-would cause the command @samp{cc foo.c /usr/lib/libcurses.a -o foo} to
-be executed when @file{foo} is older than @file{foo.c} or than
-@file{/usr/lib/libcurses.a}.@refill
-
-Although the default set of files to be searched for is
-@file{lib@var{name}.so} and @file{lib@var{name}.a}, this is customizable
-via the @code{.LIBPATTERNS} variable.  Each word in the value of this
-variable is a pattern string.  When a prerequisite like
-@samp{-l@var{name}} is seen, @code{make} will replace the percent in
-each pattern in the list with @var{name} and perform the above directory
-searches using each library file name.
-
-The default value for @code{.LIBPATTERNS} is @samp{lib%.so lib%.a},
-which provides the default behavior described above.
-
-You can turn off link library expansion completely by setting this
-variable to an empty value.

-@node Phony Targets, Force Targets, Directory Search, Rules
-@section Phony Targets
-@cindex phony targets
-@cindex targets, phony
-@cindex targets without a file
-
-A phony target is one that is not really the name of a file; rather it
-is just a name for a recipe to be executed when you make an explicit
-request.  There are two reasons to use a phony target: to avoid a
-conflict with a file of the same name, and to improve performance.
-
-If you write a rule whose recipe will not create the target file, the
-recipe will be executed every time the target comes up for remaking.
-Here is an example:
-
-@example
-@group
-clean:
-        rm *.o temp
-@end group
-@end example
-
-@noindent
-Because the @code{rm} command does not create a file named @file{clean},
-probably no such file will ever exist.  Therefore, the @code{rm} command
-will be executed every time you say @samp{make clean}.
-@cindex @code{rm} (shell command)
-
-@findex .PHONY
-In this example, the @file{clean} target will not work properly if a
-file named @file{clean} is ever created in this directory.  Since it
-has no prerequisites, @file{clean} would always be considered up to
-date and its recipe would not be executed.  To avoid this problem you
-can explicitly declare the target to be phony by making it a
-prerequisite of the special target @code{.PHONY}
-(@pxref{Special Targets, ,Special Built-in Target Names}) as follows:
-
-@example
-@group
-.PHONY: clean
-clean:
-        rm *.o temp
-@end group
-@end example
-
-@noindent
-Once this is done, @samp{make clean} will run the recipe regardless of
-whether there is a file named @file{clean}.
-
-Phony targets are also useful in conjunction with recursive
-invocations of @code{make} (@pxref{Recursion, ,Recursive Use of @code{make}}).
-In this situation the makefile will often contain a variable which
-lists a number of sub-directories to be built.  A simplistic way to
-handle this is to define one rule with a recipe that loops over the
-sub-directories, like this:
-
-@example
-@group
-SUBDIRS = foo bar baz
-
-subdirs:
-        for dir in $(SUBDIRS); do \
-          $(MAKE) -C $$dir; \
-        done
-@end group
-@end example
-
-There are problems with this method, however.  First, any error
-detected in a sub-make is ignored by this rule, so it will continue
-to build the rest of the directories even when one fails.  This can be
-overcome by adding shell commands to note the error and exit, but then
-it will do so even if @code{make} is invoked with the @code{-k}
-option, which is unfortunate.  Second, and perhaps more importantly,
-you cannot take advantage of @code{make}'s ability to build targets in
-parallel (@pxref{Parallel, ,Parallel Execution}), since there is only
-one rule.
-
-By declaring the sub-directories as @code{.PHONY} targets (you must do
-this as the sub-directory obviously always exists; otherwise it won't
-be built) you can remove these problems:
-
-@example
-@group
-SUBDIRS = foo bar baz
-
-.PHONY: subdirs $(SUBDIRS)
-
-subdirs: $(SUBDIRS)
-
-$(SUBDIRS):
-        $(MAKE) -C $@@
-
-foo: baz
-@end group
-@end example
-
-Here we've also declared that the @file{foo} sub-directory cannot be
-built until after the @file{baz} sub-directory is complete; this kind of
-relationship declaration is particularly important when attempting
-parallel builds.
-
-The implicit rule search (@pxref{Implicit Rules}) is skipped for
-@code{.PHONY} targets.  This is why declaring a target as
-@code{.PHONY} is good for performance, even if you are not worried
-about the actual file existing.
-
-A phony target should not be a prerequisite of a real target file; if it
-is, its recipe will be run every time @code{make} goes to update that
-file.  As long as a phony target is never a prerequisite of a real
-target, the phony target recipe will be executed only when the phony
-target is a specified goal (@pxref{Goals, ,Arguments to Specify the
-Goals}).
-
-Phony targets can have prerequisites.  When one directory contains multiple
-programs, it is most convenient to describe all of the programs in one
-makefile @file{./Makefile}.  Since the target remade by default will be the
-first one in the makefile, it is common to make this a phony target named
-@samp{all} and give it, as prerequisites, all the individual programs.  For
-example:
-
-@example
-all : prog1 prog2 prog3
-.PHONY : all
-
-prog1 : prog1.o utils.o
-        cc -o prog1 prog1.o utils.o
-
-prog2 : prog2.o
-        cc -o prog2 prog2.o
-
-prog3 : prog3.o sort.o utils.o
-        cc -o prog3 prog3.o sort.o utils.o
-@end example
-
-@noindent
-Now you can say just @samp{make} to remake all three programs, or
-specify as arguments the ones to remake (as in @samp{make prog1
-prog3}).  Phoniness is not inherited: the prerequisites of a phony
-target are not themselves phony, unless explicitly declared to be so.
-
-When one phony target is a prerequisite of another, it serves as a subroutine
-of the other.  For example, here @samp{make cleanall} will delete the
-object files, the difference files, and the file @file{program}:
-
-@example
-.PHONY: cleanall cleanobj cleandiff
-
-cleanall : cleanobj cleandiff
-        rm program
-
-cleanobj :
-        rm *.o
-
-cleandiff :
-        rm *.diff

-@cindex rule, no recipe or prerequisites
-
-If a rule has no prerequisites or recipe, and the target of the rule
-is a nonexistent file, then @code{make} imagines this target to have
-been updated whenever its rule is run.  This implies that all targets
-depending on this one will always have their recipe run.
-
-An example will illustrate this:

-The @dfn{empty target} is a variant of the phony target; it is used to hold
-recipes for an action that you request explicitly from time to time.
-Unlike a phony target, this target file can really exist; but the file's
-contents do not matter, and usually are empty.
-
-The purpose of the empty target file is to record, with its
-last-modification time, when the rule's recipe was last executed.  It
-does so because one of the commands in the recipe is a @code{touch}
-command to update the target file.
-
-The empty target file should have some prerequisites (otherwise it
-doesn't make sense).  When you ask to remake the empty target, the
-recipe is executed if any prerequisite is more recent than the target;
-in other words, if a prerequisite has changed since the last time you

-The high resolution file time stamps of many modern file systems

-If a file is created by such a command, you should list it as a

-example:
-
-@example
-@group
-.LOW_RESOLUTION_TIME: dst
-dst: src
-        cp -p src dst
-@end group
-@end example
-
-Since @samp{cp -p} discards the sub-second part of @file{src}'s time
-stamp, @file{dst} is typically slightly older than @file{src} even when

-@command{make} to consider @file{dst} to be up to date if its time stamp
-is at the start of the same second that @file{src}'s time stamp is in.

-
-When an explicit rule has multiple targets they can be treated in one

-The manner in which they are treated is determined by the separator that
-appears after the list of targets.
-
-@subsubheading Rules with Independent Targets
-@cindex independent targets
-@cindex targets, independent
-
-Rules that use the standard target separator, @code{:}, define
-independent targets.  This is equivalent to writing the same rule once
-for each target, with duplicated prerequisites and recipes.  Typically,
-the recipe would use automatic variables such as @samp{$@@} to specify
-which target is being built.
-
-Rules with independent targets are useful in two cases:
-
-@itemize @bullet
-@item
-You want just prerequisites, no recipe.  For example:
-
-@example
-kbd.o command.o files.o: command.h
-@end example
-
-@noindent
-gives an additional prerequisite to each of the three object files
-mentioned.  It is equivalent to writing:
-
-@example
-kbd.o: command.h
-command.o: command.h
-files.o: command.h
-@end example
-
-@item
-Similar recipes work for all the targets.  The automatic variable
-@samp{$@@} can be used to substitute the particular target to be
-remade into the commands (@pxref{Automatic Variables}).  For example:
-
-@example
-@group
-bigoutput littleoutput : text.g
-        generate text.g -$(subst output,,$@@) > $@@
-@end group
-@end example
-@findex subst
-
-@noindent
-is equivalent to
-
-@example
-bigoutput : text.g
-        generate text.g -big > bigoutput
-littleoutput : text.g
-        generate text.g -little > littleoutput
-@end example
-
-@noindent
-Here we assume the hypothetical program @code{generate} makes two
-types of output, one if given @samp{-big} and one if given
-@samp{-little}.

-for an explanation of the @code{subst} function.
-@end itemize
-
-Suppose you would like to vary the prerequisites according to the
-target, much as the variable @samp{$@@} allows you to vary the recipe.
-You cannot do this with multiple targets in an ordinary rule, but you
-can do it with a @dfn{static pattern rule}.  @xref{Static Pattern,
-,Static Pattern Rules}.
-
-@subsubheading Rules with Grouped Targets
-@cindex grouped targets
-@cindex targets, grouped
-
-If instead of independent targets you have a recipe that generates
-multiple files from a single invocation, you can express that
-relationship by declaring your rule to use @emph{grouped targets}.  A
-grouped target rule uses the separator @code{&:} (the @samp{&} here is
-used to imply ``all'').
-
-When @code{make} builds any one of the grouped targets, it understands
-that all the other targets in the group are also created as a result
-of the invocation of the recipe.  Furthermore, if only some of the
-grouped targets are out of date or missing @code{make} will realize
-that running the recipe will update all of the targets.
-
-As an example, this rule defines a grouped target:
-
-@example
-@group
-foo bar biz &: baz boz
-        echo $^ > foo
-        echo $^ > bar
-        echo $^ > biz
-@end group
-@end example
-
-During the execution of a grouped target's recipe, the automatic
-variable @samp{$@@} is set to the name of the particular target in the
-group which triggered the rule.  Caution must be used if relying on
-this variable in the recipe of a grouped target rule.
-
-Unlike independent targets, a grouped target rule @emph{must} include
-a recipe.  However, targets that are members of a grouped target may
-also appear in independent target rule definitions that do not have
-recipes.
-
-Each target may have only one recipe associated with it.  If a grouped
-target appears in either an independent target rule or in another
-grouped target rule with a recipe, you will get a warning and the
-latter recipe will replace the former recipe.  Additionally the target
-will be removed from the previous group and appear only in the new
-group.
-
-If you would like a target to appear in multiple groups, then you must
-use the double-colon grouped target separator, @code{&::} when
-declaring all of the groups containing that target.  Grouped
-double-colon targets are each considered independently, and each
-grouped double-colon rule's recipe is executed at most once, if at
-least one of its multiple targets requires updating.

-One file can be the target of several rules.  All the prerequisites
-mentioned in all the rules are merged into one list of prerequisites for
-the target.  If the target is older than any prerequisite from any rule,
-the recipe is executed.
-
-There can only be one recipe to be executed for a file.  If more than
-one rule gives a recipe for the same file, @code{make} uses the last
-one given and prints an error message.  (As a special case, if the
-file's name begins with a dot, no error message is printed.  This odd
-behavior is only for compatibility with other implementations of
-@code{make}@dots{} you should avoid using it).  Occasionally it is
-useful to have the same target invoke multiple recipes which are
-defined in different parts of your makefile; you can use
-@dfn{double-colon rules} (@pxref{Double-Colon}) for this.
-
-An extra rule with just prerequisites can be used to give a few extra
-prerequisites to many files at once.  For example, makefiles often
-have a variable, such as @code{objects}, containing a list of all the
-compiler output files in the system being made.  An easy way to say
-that all of them must be recompiled if @file{config.h} changes is to
-write the following:
-
-@example
-objects = foo.o bar.o
-foo.o : defs.h
-bar.o : defs.h test.h
-$(objects) : config.h
-@end example
-
-This could be inserted or taken out without changing the rules that really
-specify how to make the object files, making it a convenient form to use if
-you wish to add the additional prerequisite intermittently.
-
-Another wrinkle is that the additional prerequisites could be
-specified with a variable that you set with a command line argument to
-@code{make} (@pxref{Overriding, ,Overriding Variables}).  For example,
-
-@example
-@group
-extradeps=

-        @dots{}

-
-@cindex target pattern, static (not implicit)
-@cindex stem
-The @var{target-pattern} and @var{prereq-patterns} say how to compute the
-prerequisites of each target.  Each target is matched against the
-@var{target-pattern} to extract a part of the target name, called the
-@dfn{stem}.  This stem is substituted into each of the @var{prereq-patterns}
-to make the prerequisite names (one from each @var{prereq-pattern}).
-
-Each pattern normally contains the character @samp{%} just once.  When the
-@var{target-pattern} matches a target, the @samp{%} can match any part of
-the target name; this part is called the @dfn{stem}.  The rest of the
-pattern must match exactly.  For example, the target @file{foo.o} matches
-the pattern @samp{%.o}, with @samp{foo} as the stem.  The targets
-@file{foo.c} and @file{foo.out} do not match that pattern.@refill
-
-@cindex prerequisite pattern, static (not implicit)
-The prerequisite names for each target are made by substituting the stem
-for the @samp{%} in each prerequisite pattern.  For example, if one
-prerequisite pattern is @file{%.c}, then substitution of the stem
-@samp{foo} gives the prerequisite name @file{foo.c}.  It is legitimate
-to write a prerequisite pattern that does not contain @samp{%}; then this

-characters can be quoted with more backslashes.  Backslashes that quote
-@samp{%} characters or other backslashes are removed from the pattern
-before it is compared to file names or has a stem substituted into it.
-Backslashes that are not in danger of quoting @samp{%} characters go
-unmolested.  For example, the pattern @file{the\%weird\\%pattern\\} has
-@samp{the%weird\} preceding the operative @samp{%} character, and
-@samp{pattern\\} following it.  The final two backslashes are left alone
-because they cannot affect any @samp{%} character.@refill

-Here is an example, which compiles each of @file{foo.o} and @file{bar.o}
-from the corresponding @file{.c} file:
-

-Here @samp{$<} is the automatic variable that holds the name of the
-prerequisite and @samp{$@@} is the automatic variable that holds the name
-of the target; see @ref{Automatic Variables}.
-
-Each target specified must match the target pattern; a warning is issued
-for each target that does not.  If you have a list of files, only some of
-which will match the pattern, you can use the @code{filter} function to
-remove non-matching file names (@pxref{Text Functions, ,Functions for String Substitution and Analysis}):
-
-@example
-files = foo.elc bar.o lose.o
-
-$(filter %.o,$(files)): %.o: %.c

-
-@noindent
-In this example the result of @samp{$(filter %.o,$(files))} is

-these object files to be updated by compiling the corresponding C source
-file.  The result of @w{@samp{$(filter %.elc,$(files))}} is
-@file{foo.elc}, so that file is made from @file{foo.el}.@refill

-@cindex rule, static pattern versus implicit
-@cindex static pattern rule, versus implicit
-
-A static pattern rule has much in common with an implicit rule defined as a
-pattern rule (@pxref{Pattern Rules, ,Defining and Redefining Pattern Rules}).
-Both have a pattern for the target and patterns for constructing the
-names of prerequisites.  The difference is in how @code{make} decides
-@emph{when} the rule applies.
-
-An implicit rule @emph{can} apply to any target that matches its pattern,
-but it @emph{does} apply only when the target has no recipe otherwise
-specified, and only when the prerequisites can be found.  If more than one
-implicit rule appears applicable, only one applies; the choice depends on
-the order of rules.
-
-By contrast, a static pattern rule applies to the precise list of targets
-that you specify in the rule.  It cannot apply to any other target and it
-invariably does apply to each of the targets specified.  If two conflicting
-rules apply, and both have recipes, that's an error.
-
-The static pattern rule can be better than an implicit rule for these
-reasons:
-
-@itemize @bullet
-@item
-You may wish to override the usual implicit rule for a few
-files whose names cannot be categorized syntactically but
-can be given in an explicit list.
-
-@item
-If you cannot be sure of the precise contents of the directories
-you are using, you may not be sure which other irrelevant files
-might lead @code{make} to use the wrong implicit rule.  The choice
-might depend on the order in which the implicit rule search is done.
-With static pattern rules, there is no uncertainty: each rule applies
-to precisely the targets specified.

-@dfn{Double-colon} rules are explicit rules written with @samp{::}
-instead of @samp{:} after the target names.  They are handled
-differently from ordinary rules when the same target appears in more
-than one rule.  Pattern rules with double-colons have an entirely
-different meaning (@pxref{Match-Anything Rules}).
-
-When a target appears in multiple rules, all the rules must be the same
-type: all ordinary, or all double-colon.  If they are double-colon, each
-of them is independent of the others.  Each double-colon rule's recipe
-is executed if the target is older than any prerequisites of that rule.
-If there are no prerequisites for that rule, its recipe is always
-executed (even if the target already exists).  This can result in
-executing none, any, or all of the double-colon rules.
-
-Double-colon rules with the same target are in fact completely separate
-from one another.  Each double-colon rule is processed individually, just
-as rules with different targets are processed.
-
-The double-colon rules for a target are executed in the order they appear
-in the makefile.  However, the cases where double-colon rules really make
-sense are those where the order of executing the recipes would not matter.
-
-Double-colon rules are somewhat obscure and not often very useful; they
-provide a mechanism for cases in which the method used to update a target
-differs depending on which prerequisite files caused the update, and such
-cases are rare.
-
-Each double-colon rule should specify a recipe; if it does not, an

-In the makefile for a program, many of the rules you need to write often
-say only that some object file depends on some header
-file.  For example, if @file{main.c} uses @file{defs.h} via an
-@code{#include}, you would write:
-
-@example
-main.o: defs.h
-@end example
-
-@noindent
-You need this rule so that @code{make} knows that it must remake
-@file{main.o} whenever @file{defs.h} changes.  You can see that for a
-large program you would have to write dozens of such rules in your
-makefile.  And, you must always be very careful to update the makefile
-every time you add or remove an @code{#include}.
-@cindex @code{#include}
-
-@cindex @code{-M} (to compiler)
-To avoid this hassle, most modern C compilers can write these rules for
-you, by looking at the @code{#include} lines in the source files.
-Usually this is done with the @samp{-M} option to the compiler.
-For example, the command:
-
-@example
-cc -M main.c
-@end example
-
-@noindent
-generates the output:
-
-@example
-main.o : main.c defs.h
-@end example
-
-@noindent
-Thus you no longer have to write all those rules yourself.
-The compiler will do it for you.
-
-Note that such a rule constitutes mentioning @file{main.o} in a
-makefile, so it can never be considered an intermediate file by
-implicit rule search.  This means that @code{make} won't ever remove
-the file after using it; @pxref{Chained Rules, ,Chains of Implicit
-Rules}.
-
-@cindex @code{make depend}
-With old @code{make} programs, it was traditional practice to use this
-compiler feature to generate prerequisites on demand with a command like
-@samp{make depend}.  That command would create a file @file{depend}
-containing all the automatically-generated prerequisites; then the
-makefile could use @code{include} to read them in (@pxref{Include}).
-
-In GNU @code{make}, the feature of remaking makefiles makes this
-practice obsolete---you need never tell @code{make} explicitly to
-regenerate the prerequisites, because it always regenerates any makefile
-that is out of date.  @xref{Remaking Makefiles}.
-
-The practice we recommend for automatic prerequisite generation is to have
-one makefile corresponding to each source file.  For each source file
-@file{@var{name}.c} there is a makefile @file{@var{name}.d} which lists
-what files the object file @file{@var{name}.o} depends on.  That way
-only the source files that have changed need to be rescanned to produce
-the new prerequisites.
-
-Here is the pattern rule to generate a file of prerequisites (i.e., a makefile)
-called @file{@var{name}.d} from a C source file called @file{@var{name}.c}:

-
-@cindex @code{-MM} (to GNU compiler)

-@cindex syntax of recipe
-
-Makefiles have the unusual property that there are really two distinct
-syntaxes in one file.  Most of the makefile uses @code{make} syntax
-(@pxref{Makefiles, ,Writing Makefiles}).  However, recipes are meant
-to be interpreted by the shell and so they are written using shell
-syntax.  The @code{make} program does not try to understand shell
-syntax: it performs only a very few specific translations on the
-content of the recipe before handing it to the shell.
-
-Each line in the recipe must start with a tab (or the first character
-in the value of the @code{.RECIPEPREFIX} variable; @pxref{Special
-Variables}), except that the first recipe line may be attached to the
-target-and-prerequisites line with a semicolon in between.  @emph{Any}
-line in the makefile that begins with a tab and appears in a ``rule
-context'' (that is, after a rule has been started until another rule
-or variable definition) will be considered part of a recipe for that
-rule.  Blank lines and lines of just comments may appear among the
-recipe lines; they are ignored.
-
-Some consequences of these rules include:
-
-@itemize @bullet
-@item
-A blank line that begins with a tab is not blank: it's an empty
-recipe (@pxref{Empty Recipes}).
-
-@cindex comments, in recipes
-@cindex recipes, comments in
-@cindex @code{#} (comments), in recipes
-@item
-A comment in a recipe is not a @code{make} comment; it will be
-passed to the shell as-is.  Whether the shell treats it as a comment
-or not depends on your shell.
-
-@item
-A variable definition in a ``rule context'' which is indented by a tab
-as the first character on the line, will be considered part of a
-recipe, not a @code{make} variable definition, and passed to the
-shell.
-
-@item
-A conditional expression (@code{ifdef}, @code{ifeq},
-etc. @pxref{Conditional Syntax, ,Syntax of Conditionals}) in a ``rule

-@cindex newline, quoting, in recipes
-
-One of the few ways in which @code{make} does interpret recipes is
-checking for a backslash just before the newline.  As in normal
-makefile syntax, a single logical recipe line can be split into
-multiple physical lines in the makefile by placing a backslash before
-each newline.  A sequence of lines like this is considered a single
-recipe line, and one instance of the shell will be invoked to run it.
-
-However, in contrast to how they are treated in other places in a
-makefile (@pxref{Splitting Lines, , Splitting Long Lines}),
-backslash/newline pairs are @emph{not} removed from the recipe.  Both
-the backslash and the newline characters are preserved and passed to
-the shell.  How the backslash/newline is interpreted depends on your
-shell.  If the first character of the next line after the
-backslash/newline is the recipe prefix character (a tab by default;
-@pxref{Special Variables}), then that character (and only that
-character) is removed.  Whitespace is never added to the recipe.
-
-For example, the recipe for the all target in this makefile:
-
-@example
-@group
-all :
-        @@echo no\
-space
-        @@echo no\
-        space
-        @@echo one \
-        space
-        @@echo one\
-         space
-@end group
-@end example
-
-@noindent
-consists of four separate shell commands where the output is:
-
-@example
-@group
-nospace
-nospace
-one space
-one space
-@end group
-@end example
-
-As a more complex example, this makefile:
-
-@example
-@group
-all : ; @@echo 'hello \
-        world' ; echo "hello \
-    world"
-@end group
-@end example
-
-@noindent
-will invoke one shell with a command of:
-
-@example
-@group
-echo 'hello \
-world' ; echo "hello \
-    world"
-@end group
-@end example
-
-@noindent
-which, according to shell quoting rules, will yield the following output:
-
-@example
-@group
-hello \
-world
-hello     world
-@end group
-@end example
-
-@noindent
-Notice how the backslash/newline pair was removed inside the string
-quoted with double quotes (@code{"@dots{}"}), but not from the string
-quoted with single quotes (@code{'@dots{}'}).  This is the way the
-default shell (@file{/bin/sh}) handles backslash/newline pairs.  If
-you specify a different shell in your makefiles it may treat them
-differently.
-
-Sometimes you want to split a long line inside of single quotes, but
-you don't want the backslash/newline to appear in the quoted content.
-This is often the case when passing scripts to languages such as Perl,
-where extraneous backslashes inside the script can change its meaning
-or even be a syntax error.  One simple way of handling this is to
-place the quoted string, or even the entire command, into a
-@code{make} variable then use the variable in the recipe.  In this
-situation the newline quoting rules for makefiles will be used, and
-the backslash/newline will be removed.  If we rewrite our example
-above using this method:
-
-@example
-@group
-HELLO = 'hello \
-world'
-
-all : ; @@echo $(HELLO)
-@end group
-@end example
-
-@noindent
-we will get output like this:
-
-@example
-@group
-hello world
-@end group
-@end example
-
-If you like, you can also use target-specific variables
-(@pxref{Target-specific, ,Target-specific Variable Values}) to obtain
-a tighter correspondence between the variable and the recipe that
-uses it.

-@cindex variable references in recipes
-@cindex recipes, using variables in

-The other way in which @code{make} processes recipes is by expanding
-any variable references in them (@pxref{Reference,Basics of Variable
-References}).  This occurs after make has finished reading all the
-makefiles and the target is determined to be out of date; so, the
-recipes for targets which are not rebuilt are never expanded.
-
-Variable and function references in recipes have identical syntax and
-semantics to references elsewhere in the makefile.  They also have the
-same quoting rules: if you want a dollar sign to appear in your
-recipe, you must double it (@samp{$$}).  For shells like the default
-shell, that use dollar signs to introduce variables, it's important to
-keep clear in your mind whether the variable you want to reference is
-a @code{make} variable (use a single dollar sign) or a shell variable
-(use two dollar signs).  For example:
-
-@example
-@group
-LIST = one two three
-all:
-        for i in $(LIST); do \
-            echo $$i; \
-        done
-@end group
-@end example
-
-@noindent
-results in the following command being passed to the shell:
-
-@example
-@group
-for i in one two three; do \
-    echo $i; \
-done
-@end group

-Normally @code{make} prints each line of the recipe before it is

-that you are typing the lines yourself.
-
-When a line starts with @samp{@@}, the echoing of that line is suppressed.
-The @samp{@@} is discarded before the line is passed to the shell.
-Typically you would use this for a command whose only effect is to print

-@cindex @code{-n}

-only echoes most recipes, without executing them.  @xref{Options

-Sometimes you would prefer that all the lines in the recipe be passed
-to a single invocation of the shell.  There are generally two
-situations where this is useful: first, it can improve performance in
-makefiles where recipes consist of many command lines, by avoiding
-extra processes.  Second, you might want newlines to be included in
-your recipe command (for example perhaps you are using a very
-different interpreter as your @code{SHELL}).  If the @code{.ONESHELL}
-special target appears anywhere in the makefile then @emph{all}
-recipe lines for each target will be provided to a single invocation
-of the shell.  Newlines between recipe lines will be preserved.  For
-example:
-
-@example
-.ONESHELL:
-foo : bar/lose
-        cd $(@@D)
-        gobble $(@@F) > ../$@@
-@end example
-
-@noindent
-would now work as expected even though the commands are on different
-recipe lines.
-
-If @code{.ONESHELL} is provided, then only the first line of the
-recipe will be checked for the special prefix characters (@samp{@@},
-@samp{-}, and @samp{+}).  Subsequent lines will include the special
-characters in the recipe line when the @code{SHELL} is invoked.  If
-you want your recipe to start with one of these special characters
-you'll need to arrange for them to not be the first characters on the
-first line, perhaps by adding a comment or similar.  For example, this
-would be a syntax error in Perl because the first @samp{@@} is removed
-by make:
-
-@example
-.ONESHELL:
-SHELL = /usr/bin/perl
-.SHELLFLAGS = -e
-show :
-        @@f = qw(a b c);
-        print "@@f\n";
-@end example
-
-@noindent
-However, either of these alternatives would work properly:
-
-@example
-.ONESHELL:
-SHELL = /usr/bin/perl
-.SHELLFLAGS = -e
-show :
-        # Make sure "@@" is not the first character on the first line
-        @@f = qw(a b c);
-        print "@@f\n";
-@end example
-
-@noindent
-or
-
-@example
-.ONESHELL:
-SHELL = /usr/bin/perl
-.SHELLFLAGS = -e
-show :
-        my @@f = qw(a b c);
-        print "@@f\n";
-@end example
-
-As a special feature, if @code{SHELL} is determined to be a
-POSIX-style shell, the special prefix characters in ``internal''
-recipe lines will be @emph{removed} before the recipe is processed.
-This feature is intended to allow existing makefiles to add the
-@code{.ONESHELL} special target and still run properly without
-extensive modifications.  Since the special prefix characters are not
-legal at the beginning of a line in a POSIX shell script this is not a
-loss in functionality.  For example, this works as expected:
-
-@example
-.ONESHELL:
-foo : bar/lose
-        @@cd $(@@D)
-        @@gobble $(@@F) > ../$@@
-@end example
-
-Even with this special feature, however, makefiles with
-@code{.ONESHELL} will behave differently in ways that could be
-noticeable.  For example, normally if any line in the recipe fails,
-that causes the rule to fail and no more recipe lines are processed.
-Under @code{.ONESHELL} a failure of any but the final recipe line will
-not be noticed by @code{make}.  You can modify @code{.SHELLFLAGS} to
-add the @code{-e} option to the shell which will cause any failure
-anywhere in the command line to cause the shell to fail, but this
-could itself cause your recipe to behave differently.  Ultimately you
-may need to harden your recipe lines to allow them to work with
-@code{.ONESHELL}.

-@vindex .SHELLFLAGS
-The program used as the shell is taken from the variable @code{SHELL}.
-If this variable is not set in your makefile, the program
-@file{/bin/sh} is used as the shell.  The argument(s) passed to the

-
-@cindex environment, @code{SHELL} in

-use.  It would be very bad for personal choices like this to affect the
-functioning of makefiles.  @xref{Environment, ,Variables from the
-Environment}.
-
-Furthermore, when you do set @code{SHELL} in your makefile that value
-is @emph{not} exported in the environment to recipe lines that
-@code{make} invokes.  Instead, the value inherited from the user's
-environment, if any, is exported.  You can override this behavior by
-explicitly exporting @code{SHELL} (@pxref{Variables/Recursion,
-,Communicating Variables to a Sub-@code{make}}), forcing it to be
-passed in the environment to recipe lines.
-
-@vindex @code{MAKESHELL} @r{(MS-DOS alternative to @code{SHELL})}
-However, on MS-DOS and MS-Windows the value of @code{SHELL} in the
-environment @strong{is} used, since on those systems most users do not
-set this variable, and therefore it is most likely set specifically to
-be used by @code{make}.  On MS-DOS, if the setting of @code{SHELL} is
-not suitable for @code{make}, you can set the variable
-@code{MAKESHELL} to the shell that @code{make} should use; if set it
-will be used as the shell instead of the value of @code{SHELL}.

-On MS-DOS, if @code{SHELL} is not set, the value of the variable
-@code{COMSPEC} (which is always set) is used instead.
-
-@cindex @code{SHELL}, MS-DOS specifics
-The processing of lines that set the variable @code{SHELL} in Makefiles
-is different on MS-DOS.  The stock shell, @file{command.com}, is
-ridiculously limited in its functionality and many users of @code{make}
-tend to install a replacement shell.  Therefore, on MS-DOS, @code{make}
-examines the value of @code{SHELL}, and changes its behavior based on
-whether it points to a Unix-style or DOS-style shell.  This allows
-reasonable functionality even if @code{SHELL} points to
-@file{command.com}.
-
-If @code{SHELL} points to a Unix-style shell, @code{make} on MS-DOS
-additionally checks whether that shell can indeed be found; if not, it
-ignores the line that sets @code{SHELL}.  In MS-DOS, GNU @code{make}
-searches for the shell in the following places:
-
-@enumerate
-@item
-In the precise place pointed to by the value of @code{SHELL}.  For
-example, if the makefile specifies @samp{SHELL = /bin/sh}, @code{make}
-will look in the directory @file{/bin} on the current drive.
-
-@item
-In the current directory.
-
-@item
-In each of the directories in the @code{PATH} variable, in order.
-
-@end enumerate
-
-In every directory it examines, @code{make} will first look for the
-specific file (@file{sh} in the example above).  If this is not found,
-it will also look in that directory for that file with one of the known
-extensions which identify executable files.  For example @file{.exe},
-@file{.com}, @file{.bat}, @file{.btm}, @file{.sh}, and some others.
-
-If any of these attempts is successful, the value of @code{SHELL} will
-be set to the full pathname of the shell as found.  However, if none of
-these is found, the value of @code{SHELL} will not be changed, and thus
-the line that sets it will be effectively ignored.  This is so
-@code{make} will only support features specific to a Unix-style shell if
-such a shell is actually installed on the system where @code{make} runs.
-
-Note that this extended search for the shell is limited to the cases
-where @code{SHELL} is set from the Makefile; if it is set in the
-environment or command line, you are expected to set it to the full
-pathname of the shell, exactly as things are on Unix.
-
-The effect of the above DOS-specific processing is that a Makefile that
-contains @samp{SHELL = /bin/sh} (as many Unix makefiles do), will work
-on MS-DOS unaltered if you have e.g.@: @file{sh.exe} installed in some
-directory along your @code{PATH}.

-running in parallel, they will communicate so that only one of them is
-generating output at a time.
-
-If working directory printing is enabled (@pxref{-w Option, ,The
-@samp{--print-directory} Option}), the enter/leave messages are
-printed around each output grouping.  If you prefer not to see these
-messages add the @samp{--no-print-directory} option to @code{MAKEFLAGS}.
-
-There are four levels of granularity when synchronizing output,
-specified by giving an argument to the option (e.g.,  @samp{-Oline} or
-@samp{--output-sync=recurse}).
-
-@table @code
-@item none
-This is the default: all output is sent directly as it is generated and
-no synchronization is performed.
-
-@item line
-Output from each individual line of the recipe is grouped and printed
-as soon as that line is complete.  If a recipe consists of multiple
-lines, they may be interspersed with lines from other recipes.
-
-@item target
-Output from the entire recipe for each target is grouped and printed
-once the target is complete.  This is the default if the
-@code{--output-sync} or @code{-O} option is given with no argument.
-
-@item recurse
-Output from each recursive invocation of @code{make} is grouped and
-printed once the recursive invocation is complete.
-
-@end table
-
-Regardless of the mode chosen, the total build time will be the same.
-The only difference is in how the output appears.
-
-The @samp{target} and @samp{recurse} modes both collect the output of
-the entire recipe of a target and display it uninterrupted when the
-recipe completes.  The difference between them is in how recipes that
-contain recursive invocations of @code{make} are treated
-(@pxref{Recursion, ,Recursive Use of @code{make}}).  For all recipes
-which have no recursive lines, the @samp{target} and @samp{recurse}
-modes behave identically.
-
-If the @samp{recurse} mode is chosen, recipes that contain recursive
-@code{make} invocations are treated the same as other targets: the
-output from the recipe, including the output from the recursive
-@code{make}, is saved and printed after the entire recipe is complete.
-This ensures output from all the targets built by a given recursive
-@code{make} instance are grouped together, which may make the output
-easier to understand.  However it also leads to long periods of time
-during the build where no output is seen, followed by large bursts of
-output.  If you are not watching the build as it proceeds, but instead
-viewing a log of the build after the fact, this may be the best option
-for you.
-
-If you are watching the output, the long gaps of quiet during the
-build can be frustrating.  The @samp{target} output synchronization
-mode detects when @code{make} is going to be invoked recursively,
-using the standard methods, and it will not synchronize the output of
-those lines.  The recursive @code{make} will perform the
-synchronization for its targets and the output from each will be
-displayed immediately when it completes.  Be aware that output from
-recursive lines of the recipe are not synchronized (for example if
-the recursive line prints a message before running @code{make}, that
-message will not be synchronized).
-
-The @samp{line} mode can be useful for front-ends that are watching
-the output of @code{make} to track when recipes are started and
-completed.
-
-Some programs invoked by @code{make} may behave differently if they
-determine they're writing output to a terminal versus a file (often
-described as ``interactive'' vs. ``non-interactive'' modes).  For
-example, many programs that can display colorized output will not do
-so if they determine they are not writing to a terminal.  If your
-makefile invokes a program like this then using the output
-synchronization options will cause the program to believe it's running
-in ``non-interactive'' mode even though the output will ultimately go
-to the terminal.

-@subsection Input During Parallel Execution
-@cindex input during parallel execution
-@cindex parallel execution, input during
-@cindex standard input
-
-Two processes cannot both take input from the same device at the same
-time.  To make sure that only one recipe tries to take input from the
-terminal at once, @code{make} will invalidate the standard input
-streams of all but one running recipe.  If another recipe attempts to
-read from standard input it will usually incur a fatal error (a
-@samp{Broken pipe} signal).
-@cindex broken pipe
-
-It is unpredictable which recipe will have a valid standard input stream
-(which will come from the terminal, or wherever you redirect the standard
-input of @code{make}).  The first recipe run will always get it first, and
-the first recipe started after that one finishes will get it next, and so
-on.
-
-We will change how this aspect of @code{make} works if we find a better
-alternative.  In the mean time, you should not rely on any recipe using
-standard input at all if you are using the parallel execution feature; but
-if you are not using this feature, then standard input works normally in
-all recipes.

-@section Errors in Recipes
-@cindex errors (in recipes)
-@cindex recipes, errors in
-@cindex exit status (errors)
-
-After each shell invocation returns, @code{make} looks at its exit
-status.  If the shell completed successfully (the exit status is
-zero), the next line in the recipe is executed in a new shell; after
-the last line is finished, the rule is finished.
-
-If there is an error (the exit status is nonzero), @code{make} gives up on
-the current rule, and perhaps on all rules.
-
-Sometimes the failure of a certain recipe line does not indicate a problem.
-For example, you may use the @code{mkdir} command to ensure that a
-directory exists.  If the directory already exists, @code{mkdir} will
-report an error, but you probably want @code{make} to continue regardless.
-
-@cindex @code{-} (in recipes)
-To ignore errors in a recipe line, write a @samp{-} at the beginning
-of the line's text (after the initial tab).  The @samp{-} is discarded
-before the line is passed to the shell for execution.
-
-For example,
-
-@example
-@group
-clean:
-        -rm -f *.o
-@end group
-@end example
-@cindex @code{rm} (shell command)
-
-@noindent
-This causes @code{make} to continue even if @code{rm} is unable to
-remove a file.
-
-@cindex @code{-i}
-@cindex @code{--ignore-errors}
-@findex .IGNORE
-When you run @code{make} with the @samp{-i} or @samp{--ignore-errors}
-flag, errors are ignored in all recipes of all rules.  A rule in the
-makefile for the special target @code{.IGNORE} has the same effect, if
-there are no prerequisites.  This is less flexible but sometimes useful.
-
-When errors are to be ignored, because of either a @samp{-} or the
-@samp{-i} flag, @code{make} treats an error return just like success,
-except that it prints out a message that tells you the status code
-the shell exited with, and says that the error has been ignored.
-
-When an error happens that @code{make} has not been told to ignore,
-it implies that the current target cannot be correctly remade, and neither
-can any other that depends on it either directly or indirectly.  No further
-recipes will be executed for these targets, since their preconditions
-have not been achieved.
-
-
-@cindex @code{-k}
-@cindex @code{--keep-going}
-Normally @code{make} gives up immediately in this circumstance, returning a
-nonzero status.  However, if the @samp{-k} or @samp{--keep-going}
-flag is specified, @code{make}
-continues to consider the other prerequisites of the pending targets,
-remaking them if necessary, before it gives up and returns nonzero status.
-For example, after an error in compiling one object file, @samp{make -k}
-will continue compiling other object files even though it already knows
-that linking them will be impossible.  @xref{Options Summary, ,Summary of Options}.
-
-The usual behavior assumes that your purpose is to get the specified
-targets up to date; once @code{make} learns that this is impossible, it
-might as well report the failure immediately.  The @samp{-k} option says
-that the real purpose is to test as many of the changes made in the
-program as possible, perhaps to find several independent problems so
-that you can correct them all before the next attempt to compile.  This
-is why Emacs' @code{compile} command passes the @samp{-k} flag by
-default.

-@cindex target, deleting on error
-Usually when a recipe line fails, if it has changed the target file at all,
-the file is corrupted and cannot be used---or at least it is not
-completely updated.  Yet the file's time stamp says that it is now up to
-date, so the next time @code{make} runs, it will not try to update that
-file.  The situation is just the same as when the shell is killed by a
-signal; @pxref{Interrupts}.  So generally the right thing to do is to
-delete the target file if the recipe fails after beginning to change
-the file.  @code{make} will do this if @code{.DELETE_ON_ERROR} appears
-as a target.  This is almost always what you want @code{make} to do, but
-it is not historical practice; so for compatibility, you must explicitly
-request it.

-@cindex deletion of target files
-@cindex removal of target files
-@cindex target, deleting on interrupt
-@cindex killing (interruption)
-
-If @code{make} gets a fatal signal while a shell is executing, it may
-delete the target file that the recipe was supposed to update.  This is
-done if the target file's last-modification time has changed since
-@code{make} first checked it.
-
-The purpose of deleting the target is to make sure that it is remade from
-scratch when @code{make} is next run.  Why is this?  Suppose you type
-@kbd{Ctrl-c} while a compiler is running, and it has begun to write an
-object file @file{foo.o}.  The @kbd{Ctrl-c} kills the compiler, resulting
-in an incomplete file whose last-modification time is newer than the source
-file @file{foo.c}.  But @code{make} also receives the @kbd{Ctrl-c} signal
-and deletes this incomplete file.  If @code{make} did not do this, the next
-invocation of @code{make} would think that @file{foo.o} did not require
-updating---resulting in a strange error message from the linker when it
-tries to link an object file half of which is missing.
-
-@findex .PRECIOUS
-You can prevent the deletion of a target file in this way by making the
-special target @code{.PRECIOUS} depend on it.  Before remaking a target,
-@code{make} checks to see whether it appears on the prerequisites of
-@code{.PRECIOUS}, and thereby decides whether the target should be deleted
-if a signal happens.  Some reasons why you might do this are that the
-target is updated in some atomic fashion, or exists only to record a
-modification-time (its contents do not matter), or must exist at all
-times to prevent other sorts of trouble.
-
-Although @code{make} does its best to clean up there are certain situations
-in which cleanup is impossible.  For example, @code{make} may be killed by
-an uncatchable signal.  Or, one of the programs make invokes may be killed
-or crash, leaving behind an up-to-date but corrupt target file: @code{make}
-will not realize that this failure requires the target to be cleaned.  Or
-@code{make} itself may encounter a bug and crash.
-
-For these reasons it's best to write @emph{defensive recipes}, which won't
-leave behind corrupted targets even if they fail.  Most commonly these
-recipes create temporary files rather than updating the target directly,
-then rename the temporary file to the final target name.  Some compilers
-already behave this way, so that you don't need to write a defensive recipe.

-
-Recursive use of @code{make} means using @code{make} as a command in a
-makefile.  This technique is useful when you want separate makefiles for
-various subsystems that compose a larger system.  For example, suppose you
-have a sub-directory @file{subdir} which has its own makefile, and you would
-like the containing directory's makefile to run @code{make} on the
-sub-directory.  You can do it by writing this:
-
-@example
-subsystem:
-        cd subdir && $(MAKE)
-@end example
-

-@example
-subsystem:
-        $(MAKE) -C subdir
-@end example
-@cindex @code{-C}
-@cindex @code{--directory}
-
-You can write recursive @code{make} commands just by copying this example,
-but there are many things to know about how they work and why, and about
-how the sub-@code{make} relates to the top-level @code{make}.  You may
-also find it useful to declare targets that invoke recursive
-@code{make} commands as @samp{.PHONY} (for more discussion on when
-this is useful, see @ref{Phony Targets}).
-
-@vindex @code{CURDIR}
-For your convenience, when GNU @code{make} starts (after it has
-processed any @code{-C} options) it sets the variable @code{CURDIR} to
-the pathname of the current working directory.  This value is never
-touched by @code{make} again: in particular note that if you include
-files from other directories the value of @code{CURDIR} does not
-change.  The value has the same precedence it would have if it were
-set in the makefile (by default, an environment variable @code{CURDIR}
-will not override this value).  Note that setting this variable has no
-impact on the operation of @code{make} (it does not cause @code{make}

-Recursive @code{make} commands should always use the variable @code{MAKE},
-not the explicit command name @samp{make}, as shown here:
-
-@example
-@group
-subsystem:
-        cd subdir && $(MAKE)
-@end group
-@end example
-
-The value of this variable is the file name with which @code{make} was
-invoked.  If this file name was @file{/bin/make}, then the recipe executed
-is @samp{cd subdir && /bin/make}.  If you use a special version of
-@code{make} to run the top-level makefile, the same special version will be
-executed for recursive invocations.
-@cindex @code{cd} (shell command)
-
-@cindex +, and recipes
-As a special feature, using the variable @code{MAKE} in the recipe of
-a rule alters the effects of the @samp{-t} (@samp{--touch}), @samp{-n}
-(@samp{--just-print}), or @samp{-q} (@w{@samp{--question}}) option.
-Using the @code{MAKE} variable has the same effect as using a @samp{+}
-character at the beginning of the recipe line.  @xref{Instead of
-Execution, ,Instead of Executing the Recipes}.  This special feature
-is only enabled if the @code{MAKE} variable appears directly in the
-recipe: it does not apply if the @code{MAKE} variable is referenced
-through expansion of another variable.  In the latter case you must
-use the @samp{+} token to get these special effects.@refill
-
-Consider the command @samp{make -t} in the above example.  (The
-@samp{-t} option marks targets as up to date without actually running
-any recipes; see @ref{Instead of Execution}.)  Following the usual
-definition of @samp{-t}, a @samp{make -t} command in the example would
-create a file named @file{subsystem} and do nothing else.  What you
-really want it to do is run @samp{@w{cd subdir &&} @w{make -t}}; but
-that would require executing the recipe, and @samp{-t} says not to

-than you asked for.  If you give @samp{-j} with no numeric argument,
-meaning to run as many jobs as possible in parallel, this is passed
-down, since multiple infinities are no more than one.@refill
-
-If you do not want to pass the other flags down, you must change the
-value of @code{MAKEFLAGS}, like this:
-
-@example
-subsystem:
-        cd subdir && $(MAKE) MAKEFLAGS=
-@end example
-
-@vindex MAKEOVERRIDES
-The command line variable definitions really appear in the variable
-@code{MAKEOVERRIDES}, and @code{MAKEFLAGS} contains a reference to this
-variable.  If you do want to pass flags down normally, but don't want to
-pass down the command line variable definitions, you can reset
-@code{MAKEOVERRIDES} to empty, like this:
-
-@example
-MAKEOVERRIDES =
-@end example
-
-@noindent
-@cindex Arg list too long
-@cindex E2BIG
-This is not usually useful to do.  However, some systems have a small
-fixed limit on the size of the environment, and putting so much
-information into the value of @code{MAKEFLAGS} can exceed it.  If you
-see the error message @samp{Arg list too long}, this may be the problem.
-@findex .POSIX
-@cindex POSIX
-(For strict compliance with POSIX.2, changing @code{MAKEOVERRIDES} does
-not affect @code{MAKEFLAGS} if the special target @samp{.POSIX} appears
-in the makefile.  You probably do not care about this.)
-
-@vindex MFLAGS
-A similar variable @code{MFLAGS} exists also, for historical
-compatibility.  It has the same value as @code{MAKEFLAGS} except that it
-does not contain the command line variable definitions, and it always
-begins with a hyphen unless it is empty (@code{MAKEFLAGS} begins with a
-hyphen only when it begins with an option that has no single-letter
-version, such as @samp{--warn-undefined-variables}).  @code{MFLAGS} was
-traditionally used explicitly in the recursive @code{make} command, like
-this:
-
-@example
-subsystem:
-        cd subdir && $(MAKE) $(MFLAGS)
-@end example
-
-@noindent
-but now @code{MAKEFLAGS} makes this usage redundant.  If you want your
-makefiles to be compatible with old @code{make} programs, use this
-technique; it will work fine with more modern @code{make} versions too.
-
-@cindex setting options from environment
-@cindex options, setting from environment
-@cindex setting options in makefiles
-@cindex options, setting in makefiles
-The @code{MAKEFLAGS} variable can also be useful if you want to have
-certain options, such as @samp{-k} (@pxref{Options Summary, ,Summary of
-Options}), set each time you run @code{make}.  You simply put a value for
-@code{MAKEFLAGS} in your environment.  You can also set @code{MAKEFLAGS} in
-a makefile, to specify additional flags that should also be in effect for
-that makefile.  (Note that you cannot use @code{MFLAGS} this way.  That
-variable is set only for compatibility; @code{make} does not interpret a
-value you set for it in any way.)
-
-When @code{make} interprets the value of @code{MAKEFLAGS} (either from the
-environment or from a makefile), it first prepends a hyphen if the value
-does not already begin with one.  Then it chops the value into words
-separated by blanks, and parses these words as if they were options given
-on the command line (except that @samp{-C}, @samp{-f}, @samp{-h},
-@samp{-o}, @samp{-W}, and their long-named versions are ignored; and there
-is no error for an invalid option).
-
-If you do put @code{MAKEFLAGS} in your environment, you should be sure not
-to include any options that will drastically affect the actions of
-@code{make} and undermine the purpose of makefiles and of @code{make}
-itself.  For instance, the @samp{-t}, @samp{-n}, and @samp{-q} options, if
-put in one of these variables, could have disastrous consequences and would
-certainly have at least surprising and probably annoying effects.@refill
-
-If you'd like to run other implementations of @code{make} in addition
-to GNU @code{make}, and hence do not want to add GNU
-@code{make}-specific flags to the @code{MAKEFLAGS} variable, you can
-add them to the @code{GNUMAKEFLAGS} variable instead.  This variable
-is parsed just before @code{MAKEFLAGS}, in the same way as
-@code{MAKEFLAGS}.  When @code{make} constructs @code{MAKEFLAGS} to
-pass to a recursive @code{make} it will include all flags, even those
-taken from @code{GNUMAKEFLAGS}.  As a result, after parsing
-@code{GNUMAKEFLAGS} GNU @code{make} sets this variable to the empty
-string to avoid duplicating flags during recursion.
-
-It's best to use @code{GNUMAKEFLAGS} only with flags which won't
-materially change the behavior of your makefiles.  If your makefiles
-require GNU make anyway then simply use @code{MAKEFLAGS}.  Flags such
-as @samp{--no-print-directory} or @samp{--output-sync} may be
-appropriate for @code{GNUMAKEFLAGS}.

-
-When the same sequence of commands is useful in making various
-targets, you can define it as a canned sequence with the @code{define}
-directive, and refer to the canned sequence from the recipes for those
-targets.  The canned sequence is actually a variable, so the name must
-not conflict with other variable names.
-
-Here is an example of defining a canned recipe:
-
-@example
-define run-yacc =
-yacc $(firstword $^)
-mv y.tab.c $@@
-endef
-@end example
-@cindex @code{yacc}
-
-@noindent
-Here @code{run-yacc} is the name of the variable being defined;
-@code{endef} marks the end of the definition; the lines in between are the
-commands.  The @code{define} directive does not expand variable references
-and function calls in the canned sequence; the @samp{$} characters,
-parentheses, variable names, and so on, all become part of the value of the
-variable you are defining.
-@xref{Multi-Line, ,Defining Multi-Line Variables},
-for a complete explanation of @code{define}.
-
-The first command in this example runs Yacc on the first prerequisite of
-whichever rule uses the canned sequence.  The output file from Yacc is
-always named @file{y.tab.c}.  The second command moves the output to the
-rule's target file name.
-
-To use the canned sequence, substitute the variable into the recipe of a
-rule.  You can substitute it like any other variable
-(@pxref{Reference, ,Basics of Variable References}).
-Because variables defined by @code{define} are recursively expanded
-variables, all the variable references you wrote inside the @code{define}
-are expanded now.  For example:
-
-@example
-foo.c : foo.y
-        $(run-yacc)
-@end example
-
-@noindent
-@samp{foo.y} will be substituted for the variable @samp{$^} when it occurs in
-@code{run-yacc}'s value, and @samp{foo.c} for @samp{$@@}.@refill
-
-This is a realistic example, but this particular one is not needed in
-practice because @code{make} has an implicit rule to figure out these
-commands based on the file names involved
-(@pxref{Implicit Rules, ,Using Implicit Rules}).
-
-@cindex @@, and @code{define}
-@cindex -, and @code{define}
-@cindex +, and @code{define}
-In recipe execution, each line of a canned sequence is treated just as
-if the line appeared on its own in the rule, preceded by a tab.  In
-particular, @code{make} invokes a separate sub-shell for each line.  You
-can use the special prefix characters that affect command lines
-(@samp{@@}, @samp{-}, and @samp{+}) on each line of a canned sequence.
-@xref{Recipes, ,Writing Recipes in Rules}.
-For example, using this canned sequence:
-
-@example
-define frobnicate =
-@@echo "frobnicating target $@@"
-frob-step-1 $< -o $@@-step-1
-frob-step-2 $@@-step-1 -o $@@
-endef
-@end example
-
-@noindent
-@code{make} will not echo the first line, the @code{echo} command.
-But it @emph{will} echo the following two recipe lines.
-
-On the other hand, prefix characters on the recipe line that refers to
-a canned sequence apply to every line in the sequence.  So the rule:
-
-@example
-frob.out: frob.in
-        @@$(frobnicate)
-@end example
-
-@noindent
-does not echo @emph{any} recipe lines.

-
-@example
-target: ;
-@end example
-
-@noindent
-defines an empty recipe for @file{target}.  You could also use a line
-beginning with a recipe prefix character to define an empty recipe,
-but this would be confusing because such a line looks empty.
-
-@findex .DEFAULT@r{, and empty recipes}
-You may be wondering why you would want to define a recipe that does
-nothing.  One reason this is useful is to prevent a target from
-getting implicit recipes (from implicit rules or the @code{.DEFAULT}
-special target; @pxref{Implicit Rules} and @pxref{Last Resort,
-,Defining Last-Resort Default Rules}).@refill
-
-Empty recipes can also be used to avoid errors for targets that will
-be created as a side-effect of another recipe: if the target does not
-exist the empty recipe ensures that @code{make} won't complain that it
-doesn't know how to build the target, and @code{make} will assume the
-target is out of date.
-
-You may be inclined to define empty recipes for targets that are not
-actual files, but only exist so that their prerequisites can be
-remade.  However, this is not the best way to do that, because the

-does exist.  @xref{Phony Targets, ,Phony Targets}, for a better way to

-A @dfn{variable} is a name defined in a makefile to represent a string
-of text, called the variable's @dfn{value}.  These values are
-substituted by explicit request into targets, prerequisites, recipes,
-and other parts of the makefile.  (In some other versions of @code{make},

-Variables and functions in all parts of a makefile are expanded when

-
-Variables can represent lists of file names, options to pass to compilers,
-programs to run, directories to look in for source files, directories to
-write output in, or anything else you can imagine.
-
-A variable name may be any sequence of characters not containing
-@samp{:}, @samp{#}, @samp{=}, or whitespace.  However, variable names
-containing characters other than letters, numbers, and underscores
-should be considered carefully, as in some shells they cannot be
-passed through the environment to a sub-@code{make}
-(@pxref{Variables/Recursion, ,Communicating Variables to a
-Sub-@code{make}}).  Variable names beginning with @samp{.} and an
-uppercase letter may be given special meaning in future versions of
-@code{make}.
-
-Variable names are case-sensitive.  The names @samp{foo}, @samp{FOO},
-and @samp{Foo} all refer to different variables.
-
-It is traditional to use upper case letters in variable names, but we
-recommend using lower case letters for variable names that serve internal
-purposes in the makefile, and reserving upper case for parameters that
-control implicit rules or for parameters that the user should override with
-command options (@pxref{Overriding, ,Overriding Variables}).

-A few variables have names that are a single punctuation character or
-just a few characters.  These are the @dfn{automatic variables}, and

-@section Basics of Variable References
-@cindex variables, how to reference
-@cindex reference to variables
-@cindex @code{$}, in variable reference
-@cindex dollar sign (@code{$}), in variable reference
-
-To substitute a variable's value, write a dollar sign followed by the name
-of the variable in parentheses or braces: either @samp{$(foo)} or
-@samp{$@{foo@}} is a valid reference to the variable @code{foo}.  This
-special significance of @samp{$} is why you must write @samp{$$} to have
-the effect of a single dollar sign in a file name or recipe.
-
-Variable references can be used in any context: targets, prerequisites,
-recipes, most directives, and new variable values.  Here is an
-example of a common case, where a variable holds the names of all the
-object files in a program:
-
-@example
-@group
-objects = program.o foo.o utils.o
-program : $(objects)
-        cc -o program $(objects)
-
-$(objects) : defs.h
-@end group
-@end example
-
-Variable references work by strict textual substitution.  Thus, the rule
-
-@example
-@group
-foo = c
-prog.o : prog.$(foo)
-        $(foo)$(foo) -$(foo) prog.$(foo)
-@end group
-@end example
-
-@noindent
-could be used to compile a C program @file{prog.c}.  Since spaces before
-the variable value are ignored in variable assignments, the value of
-@code{foo} is precisely @samp{c}.  (Don't actually write your makefiles
-this way!)
-
-A dollar sign followed by a character other than a dollar sign,
-open-parenthesis or open-brace treats that single character as the
-variable name.  Thus, you could reference the variable @code{x} with
-@samp{$x}.  However, this practice can lead to confusion (e.g.,
-@samp{$foo} refers to the variable @code{f} followed by the string
-@code{oo}) so we recommend using parentheses or braces around all
-variables, even single-letter variables, unless omitting them gives
-significant readability improvements.  One place where readability is
-often improved is automatic variables (@pxref{Automatic Variables}).

-@section The Two Flavors of Variables
-@cindex flavors of variables
-@cindex recursive variable expansion
-@cindex variables, flavors
-@cindex recursively expanded variables
-@cindex variables, recursively expanded
-
-There are two ways that a variable in GNU @code{make} can have a value;
-we call them the two @dfn{flavors} of variables.  The two flavors are
-distinguished in how they are defined and in what they do when expanded.
-
-@cindex =
-The first flavor of variable is a @dfn{recursively expanded} variable.
-Variables of this sort are defined by lines using @samp{=}
-(@pxref{Setting, ,Setting Variables}) or by the @code{define} directive
-(@pxref{Multi-Line, ,Defining Multi-Line Variables}).  The value you specify
-is installed verbatim; if it contains references to other variables,
-these references are expanded whenever this variable is substituted (in
-the course of expanding some other string).  When this happens, it is
-called @dfn{recursive expansion}.@refill
-
-For example,
-
-@example
-foo = $(bar)
-bar = $(ugh)
-ugh = Huh?
-
-all:;echo $(foo)
-@end example
-
-@noindent
-will echo @samp{Huh?}: @samp{$(foo)} expands to @samp{$(bar)} which
-expands to @samp{$(ugh)} which finally expands to @samp{Huh?}.@refill
-
-This flavor of variable is the only sort supported by most other
-versions of @code{make}.  It has its advantages and its disadvantages.
-An advantage (most would say) is that:
-
-@example
-CFLAGS = $(include_dirs) -O
-include_dirs = -Ifoo -Ibar
-@end example
-
-@noindent
-will do what was intended: when @samp{CFLAGS} is expanded in a recipe,
-it will expand to @samp{-Ifoo -Ibar -O}.  A major disadvantage is that you
-cannot append something on the end of a variable, as in
-
-@example
-CFLAGS = $(CFLAGS) -O
-@end example
-
-@noindent
-because it will cause an infinite loop in the variable expansion.
-(Actually @code{make} detects the infinite loop and reports an error.)
-@cindex loops in variable expansion
-@cindex variables, loops in expansion
-
-Another disadvantage is that any functions
-(@pxref{Functions, ,Functions for Transforming Text})
-referenced in the definition will be executed every time the variable is
-expanded.  This makes @code{make} run slower; worse, it causes the
-@code{wildcard} and @code{shell} functions to give unpredictable results
-because you cannot easily control when they are called, or even how many
-times.
-
-To avoid all the problems and inconveniences of recursively expanded
-variables, there is another flavor: simply expanded variables.
-
-@cindex simply expanded variables
-@cindex variables, simply expanded
-@cindex :=
-@cindex ::=
-@dfn{Simply expanded variables} are defined by lines using @samp{:=}
-or @samp{::=} (@pxref{Setting, ,Setting Variables}).  Both forms are
-equivalent in GNU @code{make}; however only the @samp{::=} form is
-described by the POSIX standard (support for @samp{::=} was added to
-the POSIX standard in 2012, so older versions of @code{make} won't
-accept this form either).
-
-The value of a simply expanded variable is scanned
-once and for all, expanding any references to other variables and
-functions, when the variable is defined.  The actual value of the simply
-expanded variable is the result of expanding the text that you write.
-It does not contain any references to other variables; it contains their
-values @emph{as of the time this variable was defined}.  Therefore,
-
-@example
-x := foo
-y := $(x) bar
-x := later
-@end example
-
-@noindent
-is equivalent to
-
-@example
-y := foo bar
-x := later
-@end example
-
-When a simply expanded variable is referenced, its value is substituted
-verbatim.
-
-Here is a somewhat more complicated example, illustrating the use of
-@samp{:=} in conjunction with the @code{shell} function.
-(@xref{Shell Function, , The @code{shell} Function}.)  This example
-also shows use of the variable @code{MAKELEVEL}, which is changed
-when it is passed down from level to level.
-(@xref{Variables/Recursion, , Communicating Variables to a
-Sub-@code{make}}, for information about @code{MAKELEVEL}.)
-
-@vindex MAKELEVEL
-@vindex MAKE
-@example
-@group
-ifeq (0,$@{MAKELEVEL@})
-whoami    := $(shell whoami)
-host-type := $(shell arch)
-MAKE := $@{MAKE@} host-type=$@{host-type@} whoami=$@{whoami@}
-endif
-@end group
-@end example
-
-@noindent
-An advantage of this use of @samp{:=} is that a typical
-`descend into a directory' recipe then looks like this:
-
-@example
-@group
-$@{subdirs@}:
-        $@{MAKE@} -C $@@ all
-@end group
-@end example
-
-Simply expanded variables generally make complicated makefile programming
-more predictable because they work like variables in most programming
-languages.  They allow you to redefine a variable using its own value (or
-its value processed in some way by one of the expansion functions) and to
-use the expansion functions much more efficiently
-(@pxref{Functions, ,Functions for Transforming Text}).
-
-@cindex spaces, in variable values
-@cindex whitespace, in variable values
-@cindex variables, spaces in values
-You can also use them to introduce controlled leading whitespace into
-variable values.  Leading whitespace characters are discarded from your
-input before substitution of variable references and function calls;
-this means you can include leading spaces in a variable value by
-protecting them with variable references, like this:
-
-@example
-nullstring :=
-space := $(nullstring) # end of the line
-@end example
-
-@noindent
-Here the value of the variable @code{space} is precisely one space.  The
-comment @w{@samp{# end of the line}} is included here just for clarity.
-Since trailing space characters are @emph{not} stripped from variable
-values, just a space at the end of the line would have the same effect
-(but be rather hard to read).  If you put whitespace at the end of a
-variable value, it is a good idea to put a comment like that at the end
-of the line to make your intent clear.  Conversely, if you do @emph{not}
-want any whitespace characters at the end of your variable value, you
-must remember not to put a random comment on the end of the line after
-some whitespace, such as this:
-
-@example
-dir := /foo/bar    # directory to put the frobs in
-@end example
-
-@noindent
-Here the value of the variable @code{dir} is @w{@samp{/foo/bar    }}
-(with four trailing spaces), which was probably not the intention.
-(Imagine something like @w{@samp{$(dir)/file}} with this definition!)
-
-@cindex conditional variable assignment
-@cindex variables, conditional assignment
-@cindex ?=
-There is another assignment operator for variables, @samp{?=}.  This
-is called a conditional variable assignment operator, because it only
-has an effect if the variable is not yet defined.  This statement:
-
-@example
-FOO ?= bar
-@end example
-
-@noindent
-is exactly equivalent to this
-(@pxref{Origin Function, ,The @code{origin} Function}):
-
-@example
-ifeq ($(origin FOO), undefined)
-  FOO = bar
-endif
-@end example
-
-Note that a variable set to an empty value is still defined, so
-@samp{?=} will not set that variable.

-@cindex variables, nested references
-@cindex variables, @samp{$} in name
-@cindex @code{$}, in variable name
-@cindex dollar sign (@code{$}), in variable name
-
-Computed variable names are a complicated concept needed only for
-sophisticated makefile programming.  For most purposes you need not
-consider them, except to know that making a variable with a dollar sign
-in its name might have strange results.  However, if you are the type
-that wants to understand everything, or you are actually interested in
-what they do, read on.
-
-Variables may be referenced inside the name of a variable.  This is
-called a @dfn{computed variable name} or a @dfn{nested variable
-reference}.  For example,
-
-@example
-x = y
-y = z
-a := $($(x))
-@end example
-
-@noindent
-defines @code{a} as @samp{z}: the @samp{$(x)} inside @samp{$($(x))} expands
-to @samp{y}, so @samp{$($(x))} expands to @samp{$(y)} which in turn expands
-to @samp{z}.  Here the name of the variable to reference is not stated
-explicitly; it is computed by expansion of @samp{$(x)}.  The reference
-@samp{$(x)} here is nested within the outer variable reference.
-
-The previous example shows two levels of nesting, but any number of levels
-is possible.  For example, here are three levels:
-
-@example
-x = y
-y = z
-z = u
-a := $($($(x)))
-@end example
-
-@noindent
-Here the innermost @samp{$(x)} expands to @samp{y}, so @samp{$($(x))}
-expands to @samp{$(y)} which in turn expands to @samp{z}; now we have
-@samp{$(z)}, which becomes @samp{u}.
-
-References to recursively-expanded variables within a variable name are
-re-expanded in the usual fashion.  For example:
-
-@example
-x = $(y)
-y = z
-z = Hello
-a := $($(x))
-@end example
-
-@noindent
-defines @code{a} as @samp{Hello}: @samp{$($(x))} becomes @samp{$($(y))}
-which becomes @samp{$(z)} which becomes @samp{Hello}.
-
-Nested variable references can also contain modified references and
-function invocations (@pxref{Functions, ,Functions for Transforming Text}),
-just like any other reference.
-For example, using the @code{subst} function
-(@pxref{Text Functions, ,Functions for String Substitution and Analysis}):
-
-@example
-@group
-x = variable1
-variable2 := Hello
-y = $(subst 1,2,$(x))
-z = y
-a := $($($(z)))
-@end group
-@end example
-
-@noindent
-eventually defines @code{a} as @samp{Hello}.  It is doubtful that anyone
-would ever want to write a nested reference as convoluted as this one, but
-it works: @samp{$($($(z)))} expands to @samp{$($(y))} which becomes
-@samp{$($(subst 1,2,$(x)))}.  This gets the value @samp{variable1} from
-@code{x} and changes it by substitution to @samp{variable2}, so that the
-entire string becomes @samp{$(variable2)}, a simple variable reference
-whose value is @samp{Hello}.@refill
-
-A computed variable name need not consist entirely of a single variable
-reference.  It can contain several variable references, as well as some
-invariant text.  For example,
-
-@example
-@group
-a_dirs := dira dirb
-1_dirs := dir1 dir2
-@end group
-
-@group
-a_files := filea fileb
-1_files := file1 file2
-@end group
-
-@group
-ifeq "$(use_a)" "yes"
-a1 := a
-else
-a1 := 1
-endif
-@end group
-
-@group
-ifeq "$(use_dirs)" "yes"
-df := dirs
-else
-df := files
-endif
-
-dirs := $($(a1)_$(df))
-@end group
-@end example
-
-@noindent
-will give @code{dirs} the same value as @code{a_dirs}, @code{1_dirs},
-@code{a_files} or @code{1_files} depending on the settings of @code{use_a}
-and @code{use_dirs}.@refill
-
-Computed variable names can also be used in substitution references:
-
-@example
-@group
-a_objects := a.o b.o c.o
-1_objects := 1.o 2.o 3.o
-
-sources := $($(a1)_objects:.o=.c)
-@end group
-@end example
-
-@noindent
-defines @code{sources} as either @samp{a.c b.c c.c} or @samp{1.c 2.c 3.c},
-depending on the value of @code{a1}.
-
-The only restriction on this sort of use of nested variable references
-is that they cannot specify part of the name of a function to be called.
-This is because the test for a recognized function name is done before
-the expansion of nested references.  For example,
-
-@example
-@group
-ifdef do_sort
-func := sort
-else
-func := strip
-endif
-@end group
-
-@group
-bar := a d b g q c
-@end group
-
-@group
-foo := $($(func) $(bar))
-@end group
-@end example
-
-@noindent
-attempts to give @samp{foo} the value of the variable @samp{sort a d b g
-q c} or @samp{strip a d b g q c}, rather than giving @samp{a d b g q c}
-as the argument to either the @code{sort} or the @code{strip} function.
-This restriction could be removed in the future if that change is shown
-to be a good idea.
-
-You can also use computed variable names in the left-hand side of a
-variable assignment, or in a @code{define} directive, as in:
-
-@example
-dir = foo
-$(dir)_sources := $(wildcard $(dir)/*.c)
-define $(dir)_print =
-lpr $($(dir)_sources)
-endef
-@end example
-
-@noindent
-This example defines the variables @samp{dir}, @samp{foo_sources}, and
-@samp{foo_print}.
-

-@dfn{recursively expanded variables}

-To set a variable from the makefile, write a line starting with the
-variable name followed by @samp{=}, @samp{:=}, or @samp{::=}.  Whatever
-follows the @samp{=}, @samp{:=}, or @samp{::=} on the line becomes the
-value.  For example,
-
-@example
-objects = main.o foo.o bar.o utils.o
-@end example
-
-@noindent
-defines a variable named @code{objects}.  Whitespace around the variable
-name and immediately after the @samp{=} is ignored.
-
-Variables defined with @samp{=} are @dfn{recursively expanded}
-variables.  Variables defined with @samp{:=} or @samp{::=} are
-@dfn{simply expanded} variables; these definitions can contain
-variable references which will be expanded before the definition is
-made.  @xref{Flavors, ,The Two Flavors of Variables}.
-
-The variable name may contain function and variable references, which
-are expanded when the line is read to find the actual variable name to use.
-
-There is no limit on the length of the value of a variable except the
-amount of memory on the computer.  You can split the value of a
-variable into multiple physical lines for readability
-(@pxref{Splitting Lines, ,Splitting Long Lines}).
-
-Most variable names are considered to have the empty string as a value if
-you have never set them.  Several variables have built-in initial values
-that are not empty, but you can set them in the usual ways
-(@pxref{Implicit Variables, ,Variables Used by Implicit Rules}).
-Several special variables are set
-automatically to a new value for each rule; these are called the
-@dfn{automatic} variables (@pxref{Automatic Variables}).
-
-If you'd like a variable to be set to a value only if it's not already
-set, then you can use the shorthand operator @samp{?=} instead of
-@samp{=}.  These two settings of the variable @samp{FOO} are identical
-(@pxref{Origin Function, ,The @code{origin} Function}):
-
-@example
-FOO ?= bar
-@end example
-
-@noindent
-and
-
-@example
-ifeq ($(origin FOO), undefined)
-FOO = bar
-endif
-@end example
-
-The shell assignment operator @samp{!=} can be used to execute a
-shell script and set a variable to its output.  This operator first
-evaluates the right-hand side, then passes that result to the shell
-for execution.  If the result of the execution ends in a newline, that
-one newline is removed; all other newlines are replaced by spaces.
-The resulting string is then placed into the named
-recursively-expanded variable.  For example:
-
-@example
-hash != printf '\043'
-file_list != find . -name '*.c'
-@end example
-
-If the result of the execution could produce a @code{$}, and you don't
-intend what follows that to be interpreted as a make variable or
-function reference, then you must replace every @code{$} with
-@code{$$} as part of the execution.  Alternatively, you can set a
-simply expanded variable to the result of running a program using the
-@code{shell} function call.  @xref{Shell Function, , The @code{shell}
-Function}.  For example:
-
-@example
-hash := $(shell printf '\043')
-var := $(shell find . -name "*.c")
-@end example
-
-As with the @code{shell} function, the exit status of the just-invoked
-shell script is stored in the @code{.SHELLSTATUS} variable.

-@section Appending More Text to Variables
-@cindex +=
-@cindex appending to variables
-@cindex variables, appending to
-
-Often it is useful to add more text to the value of a variable already defined.
-You do this with a line containing @samp{+=}, like this:
-
-@example
-objects += another.o
-@end example
-
-@noindent
-This takes the value of the variable @code{objects}, and adds the text
-@samp{another.o} to it (preceded by a single space, if it has a value
-already).  Thus:
-
-@example
-objects = main.o foo.o bar.o utils.o
-objects += another.o
-@end example
-
-@noindent
-sets @code{objects} to @samp{main.o foo.o bar.o utils.o another.o}.
-
-Using @samp{+=} is similar to:
-
-@example
-objects = main.o foo.o bar.o utils.o
-objects := $(objects) another.o
-@end example
-
-@noindent
-but differs in ways that become important when you use more complex values.
-
-When the variable in question has not been defined before, @samp{+=}
-acts just like normal @samp{=}: it defines a recursively-expanded
-variable.  However, when there @emph{is} a previous definition, exactly
-what @samp{+=} does depends on what flavor of variable you defined
-originally.  @xref{Flavors, ,The Two Flavors of Variables}, for an
-explanation of the two flavors of variables.
-
-When you add to a variable's value with @samp{+=}, @code{make} acts
-essentially as if you had included the extra text in the initial
-definition of the variable.  If you defined it first with @samp{:=} or
-@samp{::=}, making it a simply-expanded variable, @samp{+=} adds to
-that simply-expanded definition, and expands the new text before
-appending it to the old value just as @samp{:=} does (see
-@ref{Setting, ,Setting Variables}, for a full explanation of
-@samp{:=} or @samp{::=}).  In fact,
-
-@example
-variable := value
-variable += more
-@end example
-
-@noindent
-is exactly equivalent to:
-
-@noindent
-@example
-variable := value
-variable := $(variable) more
-@end example
-
-On the other hand, when you use @samp{+=} with a variable that you defined
-first to be recursively-expanded using plain @samp{=}, @code{make} does
-something a bit different.  Recall that when you define a
-recursively-expanded variable, @code{make} does not expand the value you set
-for variable and function references immediately.  Instead it stores the text
-verbatim, and saves these variable and function references to be expanded
-later, when you refer to the new variable (@pxref{Flavors, ,The Two Flavors
-of Variables}).  When you use @samp{+=} on a recursively-expanded variable,
-it is this unexpanded text to which @code{make} appends the new text you
-specify.
-
-@example
-@group
-variable = value
-variable += more
-@end group
-@end example
-
-@noindent
-is roughly equivalent to:
-
-@example
-@group
-temp = value
-variable = $(temp) more
-@end group
-@end example
-
-@noindent
-except that of course it never defines a variable called @code{temp}.
-The importance of this comes when the variable's old value contains
-variable references.  Take this common example:
-
-@example
-CFLAGS = $(includes) -O
-@dots{}
-CFLAGS += -pg # enable profiling
-@end example
-
-@noindent
-The first line defines the @code{CFLAGS} variable with a reference to another
-variable, @code{includes}.  (@code{CFLAGS} is used by the rules for C
-compilation; @pxref{Catalogue of Rules, ,Catalogue of Built-In Rules}.)
-Using @samp{=} for the definition makes @code{CFLAGS} a recursively-expanded
-variable, meaning @w{@samp{$(includes) -O}} is @emph{not} expanded when
-@code{make} processes the definition of @code{CFLAGS}.  Thus, @code{includes}
-need not be defined yet for its value to take effect.  It only has to be
-defined before any reference to @code{CFLAGS}.  If we tried to append to the
-value of @code{CFLAGS} without using @samp{+=}, we might do it like this:
-
-@example
-CFLAGS := $(CFLAGS) -pg # enable profiling
-@end example
-
-@noindent
-This is pretty close, but not quite what we want.  Using @samp{:=}
-redefines @code{CFLAGS} as a simply-expanded variable; this means
-@code{make} expands the text @w{@samp{$(CFLAGS) -pg}} before setting the
-variable.  If @code{includes} is not yet defined, we get @w{@samp{ -O
--pg}}, and a later definition of @code{includes} will have no effect.
-Conversely, by using @samp{+=} we set @code{CFLAGS} to the
-@emph{unexpanded} value @w{@samp{$(includes) -O -pg}}.  Thus we preserve
-the reference to @code{includes}, so if that variable gets defined at
-any later point, a reference like @samp{$(CFLAGS)} still uses its
-value.

-
-If a variable has been set with a command argument
-(@pxref{Overriding, ,Overriding Variables}),
-then ordinary assignments in the makefile are ignored.  If you want to set
-the variable in the makefile even though it was set with a command
-argument, you can use an @code{override} directive, which is a line that
-looks like this:@refill
-
-@example
-override @var{variable} = @var{value}
-@end example
-
-@noindent
-or
-
-@example
-override @var{variable} := @var{value}

-To append more text to a variable defined on the command line, use:
-
-@example
-override @var{variable} += @var{more text}
-@end example
-
-@noindent
-@xref{Appending, ,Appending More Text to Variables}.
-
-Variable assignments marked with the @code{override} flag have a
-higher priority than all other assignments, except another
-@code{override}.  Subsequent assignments or appends to this variable
-which are not marked @code{override} will be ignored.
-
-The @code{override} directive was not invented for escalation in the war
-between makefiles and command arguments.  It was invented so you can alter
-and add to values that the user specifies with command arguments.
-
-For example, suppose you always want the @samp{-g} switch when you run the
-C compiler, but you would like to allow the user to specify the other
-switches with a command argument just as usual.  You could use this
-@code{override} directive:
-
-@example
-override CFLAGS += -g
-@end example
-
-You can also use @code{override} directives with @code{define} directives.
-This is done as you might expect:
-
-@example
-override define foo =
-bar
-endef
-@end example
-
-@noindent
-@iftex

-
-Another way to set the value of a variable is to use the @code{define}
-directive.  This directive has an unusual syntax which allows newline
-characters to be included in the value, which is convenient for
-defining both canned sequences of commands (@pxref{Canned Recipes,
-,Defining Canned Recipes}), and also sections of makefile syntax to
-use with @code{eval} (@pxref{Eval Function}).@refill
-
-The @code{define} directive is followed on the same line by the name
-of the variable being defined and an (optional) assignment operator,
-and nothing more.  The value to give the variable appears on the
-following lines.  The end of the value is marked by a line containing
-just the word @code{endef}.
-
-Aside from this difference in syntax, @code{define} works just like
-any other variable definition.  The variable name may contain function
-and variable references, which are expanded when the directive is read
-to find the actual variable name to use.
-
-The final newline before the @code{endef} is not included in the
-value; if you want your value to contain a trailing newline you must
-include a blank line.  For example in order to define a variable that
-contains a newline character you must use @emph{two} empty lines, not one:
-
-@example
-define newline
-
-
-endef
-@end example
-
-You may omit the variable assignment operator if you prefer.  If
-omitted, @code{make} assumes it to be @samp{=} and creates a
-recursively-expanded variable (@pxref{Flavors, ,The Two Flavors of Variables}).
-When using a @samp{+=} operator, the value is appended to the previous
-value as with any other append operation: with a single space
-separating the old and new values.
-
-You may nest @code{define} directives: @code{make} will keep track of
-nested directives and report an error if they are not all properly
-closed with @code{endef}.  Note that lines beginning with the recipe
-prefix character are considered part of a recipe, so any @code{define}
-or @code{endef} strings appearing on such a line will not be
-considered @code{make} directives.
-
-@example
-define two-lines
-echo foo
-echo $(bar)
-endef
-@end example
-
-@need 800
-When used in a recipe, the previous example is functionally equivalent
-to this:
-
-@example
-two-lines = echo foo; echo $(bar)
-@end example
-
-@noindent
-since two commands separated by semicolon behave much like two separate
-shell commands.  However, note that using two separate lines means
-@code{make} will invoke the shell twice, running an independent sub-shell
-for each line.  @xref{Execution, ,Recipe Execution}.
-
-If you want variable definitions made with @code{define} to take
-precedence over command-line variable definitions, you can use the
-@code{override} directive together with @code{define}:
-

-override define two-lines =

-If you want to clear a variable, setting its value to empty is usually
-sufficient. Expanding such a variable will yield the same result (empty
-string) regardless of whether it was set or not. However, if you are
-using the @code{flavor} (@pxref{Flavor Function}) and
-@code{origin} (@pxref{Origin Function}) functions, there is a difference
-between a variable that was never set and a variable with an empty value.
-In such situations you may want to use the @code{undefine} directive to
-make a variable appear as if it was never set. For example:
-
-@example
-foo := foo
-bar = bar
-
-undefine foo
-undefine bar
-
-$(info $(origin foo))
-$(info $(flavor bar))
-@end example
-
-This example will print ``undefined'' for both variables.
-
-If you want to undefine a command-line variable definition, you can use

-

-override undefine CFLAGS

-@cindex variables, environment
-@cindex environment
-Variables in @code{make} can come from the environment in which
-@code{make} is run.  Every environment variable that @code{make} sees
-when it starts up is transformed into a @code{make} variable with the
-same name and value.  However, an explicit assignment in the makefile,
-or with a command argument, overrides the environment.  (If the
-@samp{-e} flag is specified, then values from the environment override
-assignments in the makefile.  @xref{Options Summary, ,Summary of
-Options}.  But this is not recommended practice.)
-
-Thus, by setting the variable @code{CFLAGS} in your environment, you can
-cause all C compilations in most makefiles to use the compiler switches you
-prefer.  This is safe for variables with standard or conventional meanings
-because you know that no makefile will use them for other things.  (Note
-this is not totally reliable; some makefiles set @code{CFLAGS} explicitly
-and therefore are not affected by the value in the environment.)
-
-When @code{make} runs a recipe, variables defined in the
-makefile are placed into the environment of each shell.  This allows
-you to pass values to sub-@code{make} invocations (@pxref{Recursion,
-,Recursive Use of @code{make}}).  By default, only variables that came
-from the environment or the command line are passed to recursive
-invocations.  You can use the @code{export} directive to pass other
-variables.  @xref{Variables/Recursion, , Communicating Variables to a
-Sub-@code{make}}, for full details.
-
-Other use of variables from the environment is not recommended.  It is not
-wise for makefiles to depend for their functioning on environment variables
-set up outside their control, since this would cause different users to get
-different results from the same makefile.  This is against the whole
-purpose of most makefiles.

-@cindex SHELL, import from environment
-Such problems would be especially likely with the variable

-Set a target-specific variable value like this:
-
-@example
-@var{target} @dots{} : @var{variable-assignment}
-@end example
-
-Target-specific variable assignments can be prefixed with any or all of the
-special keywords @code{export}, @code{override}, or @code{private};
-these apply their normal behavior to this instance of the variable only.
-
-Multiple @var{target} values create a target-specific variable value for
-each member of the target list individually.
-
-The @var{variable-assignment} can be any valid form of assignment;
-recursive (@samp{=}), simple (@samp{:=} or @samp{::=}), appending
-(@samp{+=}), or conditional (@samp{?=}).  All variables that appear
-within the @var{variable-assignment} are evaluated within the context
-of the target: thus, any previously-defined target-specific variable
-values will be in effect.  Note that this variable is actually
-distinct from any ``global'' value: the two variables do not have to
-have the same flavor (recursive vs.@: simple).
-
-Target-specific variables have the same priority as any other makefile
-variable.  Variables provided on the command line (and in the
-environment if the @samp{-e} option is in force) will take precedence.
-Specifying the @code{override} directive will allow the target-specific
-variable value to be preferred.
-
-There is one more special feature of target-specific variables: when
-you define a target-specific variable that variable value is also in
-effect for all prerequisites of this target, and all their
-prerequisites, etc.@: (unless those prerequisites override that variable
-with their own target-specific variable value).  So, for example, a
-statement like this:
-
-@example
-prog : CFLAGS = -g
-prog : prog.o foo.o bar.o
-@end example
-
-@noindent
-will set @code{CFLAGS} to @samp{-g} in the recipe for @file{prog}, but
-it will also set @code{CFLAGS} to @samp{-g} in the recipes that create
-@file{prog.o}, @file{foo.o}, and @file{bar.o}, and any recipes which
-create their prerequisites.
-
-Be aware that a given prerequisite will only be built once per
-invocation of make, at most.  If the same file is a prerequisite of
-multiple targets, and each of those targets has a different value for
-the same target-specific variable, then the first target to be built
-will cause that prerequisite to be built and the prerequisite will
-inherit the target-specific value from the first target.  It will
-ignore the target-specific values from any other targets.

-In addition to target-specific variable values
-(@pxref{Target-specific, ,Target-specific Variable Values}), GNU
-@code{make} supports pattern-specific variable values.  In this form,
-the variable is defined for any target that matches the pattern
-specified.
-
-Set a pattern-specific variable value like this:
-
-@example
-@var{pattern} @dots{} : @var{variable-assignment}
-@end example
-where @var{pattern} is a %-pattern.  As with target-specific variable
-values, multiple @var{pattern} values create a pattern-specific variable
-value for each pattern individually.  The @var{variable-assignment} can
-be any valid form of assignment.  Any command line variable setting will
-take precedence, unless @code{override} is specified.
-
-For example:
-
-@example
-%.o : CFLAGS = -O
-@end example
-
-@noindent
-will assign @code{CFLAGS} the value of @samp{-O} for all targets
-matching the pattern @code{%.o}.
-
-If a target matches more than one pattern, the matching pattern-specific
-variables with longer stems are interpreted first. This results in more
-specific variables taking precedence over the more generic ones, for
-example:
-
-@example
-%.o: %.c
-        $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@@
-
-lib/%.o: CFLAGS := -fPIC -g
-%.o: CFLAGS := -g
-
-all: foo.o lib/bar.o
-@end example
-
-In this example the first definition of the @code{CFLAGS} variable
-will be used to update @file{lib/bar.o} even though the second one
-also applies to this target. Pattern-specific variables which result
-in the same stem length are considered in the order in which they
-were defined in the makefile.
-
-Pattern-specific variables are searched after any target-specific
-variables defined explicitly for that target, and before target-specific
-variables defined for the parent target.

-As described in previous sections, @code{make} variables are inherited
-by prerequisites.  This capability allows you to modify the behavior
-of a prerequisite based on which targets caused it to be rebuilt.  For
-example, you might set a target-specific variable on a @code{debug}
-target, then running @samp{make debug} will cause that variable to be
-inherited by all prerequisites of @code{debug}, while just running
-@samp{make all} (for example) would not have that assignment.
-
-Sometimes, however, you may not want a variable to be inherited.  For
-these situations, @code{make} provides the @code{private} modifier.
-Although this modifier can be used with any variable assignment, it
-makes the most sense with target- and pattern-specific variables.  Any
-variable marked @code{private} will be visible to its local target but
-will not be inherited by prerequisites of that target.  A global
-variable marked @code{private} will be visible in the global scope but
-will not be inherited by any target, and hence will not be visible
-in any recipe.
-
-As an example, consider this makefile:
-@example
-EXTRA_CFLAGS =
-
-prog: private EXTRA_CFLAGS = -L/usr/local/lib
-prog: a.o b.o
-@end example
-
-Due to the @code{private} modifier, @code{a.o} and @code{b.o} will not
-inherit the @code{EXTRA_CFLAGS} variable assignment from the
-@code{prog} target.

-Each word in this variable is a new prerequisite which is added to
-targets for which it is set.  These prerequisites differ from normal
-prerequisites in that they do not appear in any of the automatic
-variables (@pxref{Automatic Variables}).  This allows prerequisites to
-be defined which do not impact the recipe.
-
-Consider a rule to link a program:
-
-@example
-myprog: myprog.o file1.o file2.o
-       $(CC) $(CFLAGS) $(LDFLAGS) -o $@@ $^ $(LDLIBS)
-@end example
-
-Now suppose you want to enhance this makefile to ensure that updates
-to the compiler cause the program to be re-linked.  You can add the
-compiler as a prerequisite, but you must ensure that it's not passed
-as an argument to link command.  You'll need something like this:
-
-@example
-myprog: myprog.o file1.o file2.o $(CC)
-       $(CC) $(CFLAGS) $(LDFLAGS) -o $@@ $(filter-out $(CC),$^) $(LDLIBS)
-@end example
-
-Then consider having multiple extra prerequisites: they would all have
-to be filtered out.  Using @code{.EXTRA_PREREQS} and target-specific
-variables provides a simpler solution:
-
-@example
-myprog: myprog.o file1.o file2.o
-       $(CC) $(CFLAGS) $(LDFLAGS) -o $@@ $^ $(LDLIBS)
-myprog: .EXTRA_PREREQS = $(CC)
-@end example
-
-This feature can also be useful if you want to add prerequisites to a
-makefile you cannot easily modify: you can create a new file such as
-@file{extra.mk}:
-
-@example
-myprog: .EXTRA_PREREQS = $(CC)
-@end example
-
-then invoke @code{make -f extra.mk -f Makefile}.
-
-Setting @code{.EXTRA_PREREQS} globally will cause those prerequisites
-to be added to all targets (which did not themselves override it with
-a target-specific value).  Note @code{make} is smart enough not to add
-a prerequisite listed in @code{.EXTRA_PREREQS} as a prerequisite to
-itself.

-@section Example of a Conditional
-
-The following example of a conditional tells @code{make} to use one
-set of libraries if the @code{CC} variable is @samp{gcc}, and a
-different set of libraries otherwise.  It works by controlling which
-of two recipe lines will be used for the rule.  The result is that
-@samp{CC=gcc} as an argument to @code{make} changes not only which
-compiler is used but also which libraries are linked.
-
-@example
-libs_for_gcc = -lgnu
-normal_libs =
-
-foo: $(objects)
-ifeq ($(CC),gcc)
-        $(CC) -o foo $(objects) $(libs_for_gcc)
-else
-        $(CC) -o foo $(objects) $(normal_libs)
-endif
-@end example
-
-This conditional uses three directives: one @code{ifeq}, one @code{else}
-and one @code{endif}.
-
-The @code{ifeq} directive begins the conditional, and specifies the
-condition.  It contains two arguments, separated by a comma and surrounded
-by parentheses.  Variable substitution is performed on both arguments and
-then they are compared.  The lines of the makefile following the
-@code{ifeq} are obeyed if the two arguments match; otherwise they are
-ignored.
-
-The @code{else} directive causes the following lines to be obeyed if the
-previous conditional failed.  In the example above, this means that the
-second alternative linking command is used whenever the first alternative
-is not used.  It is optional to have an @code{else} in a conditional.
-
-The @code{endif} directive ends the conditional.  Every conditional must
-end with an @code{endif}.  Unconditional makefile text follows.
-
-As this example illustrates, conditionals work at the textual level:
-the lines of the conditional are treated as part of the makefile, or
-ignored, according to the condition.  This is why the larger syntactic
-units of the makefile, such as rules, may cross the beginning or the
-end of the conditional.
-
-When the variable @code{CC} has the value @samp{gcc}, the above example has
-this effect:
-
-@example
-foo: $(objects)
-        $(CC) -o foo $(objects) $(libs_for_gcc)
-@end example
-
-@noindent
-When the variable @code{CC} has any other value, the effect is this:
-
-@example
-foo: $(objects)
-        $(CC) -o foo $(objects) $(normal_libs)
-@end example
-
-Equivalent results can be obtained in another way by conditionalizing a
-variable assignment and then using the variable unconditionally:
-
-@example
-libs_for_gcc = -lgnu
-normal_libs =
-
-ifeq ($(CC),gcc)
-  libs=$(libs_for_gcc)
-else
-  libs=$(normal_libs)
-endif
-
-foo: $(objects)
-        $(CC) -o foo $(objects) $(libs)
-@end example

-
-The syntax of a simple conditional with no @code{else} is as follows:
-
-@example
-@var{conditional-directive}
-@var{text-if-true}
-endif
-@end example
-
-@noindent
-The @var{text-if-true} may be any lines of text, to be considered as part
-of the makefile if the condition is true.  If the condition is false, no
-text is used instead.
-
-The syntax of a complex conditional is as follows:
-
-@example
-@var{conditional-directive}
-@var{text-if-true}
-else
-@var{text-if-false}
-endif
-@end example
-
-or:
-
-@example
-@var{conditional-directive-one}
-@var{text-if-one-is-true}
-else @var{conditional-directive-two}
-@var{text-if-two-is-true}
-else
-@var{text-if-one-and-two-are-false}
-endif
-@end example
-
-@noindent
-There can be as many ``@code{else} @var{conditional-directive}''
-clauses as necessary.  Once a given condition is true,
-@var{text-if-true} is used and no other clause is used; if no
-condition is true then @var{text-if-false} is used.  The
-@var{text-if-true} and @var{text-if-false} can be any number of lines
-of text.
-
-The syntax of the @var{conditional-directive} is the same whether the
-conditional is simple or complex; after an @code{else} or not.  There
-are four different directives that test different conditions.  Here is
-a table of them:
-
-@table @code
-@item ifeq (@var{arg1}, @var{arg2})
-@itemx ifeq '@var{arg1}' '@var{arg2}'
-@itemx ifeq "@var{arg1}" "@var{arg2}"
-@itemx ifeq "@var{arg1}" '@var{arg2}'
-@itemx ifeq '@var{arg1}' "@var{arg2}"
-Expand all variable references in @var{arg1} and @var{arg2} and
-compare them.  If they are identical, the @var{text-if-true} is
-effective; otherwise, the @var{text-if-false}, if any, is effective.
-
-Often you want to test if a variable has a non-empty value.  When the
-value results from complex expansions of variables and functions,
-expansions you would consider empty may actually contain whitespace
-characters and thus are not seen as empty.  However, you can use the
-@code{strip} function (@pxref{Text Functions}) to avoid interpreting
-whitespace as a non-empty value.  For example:
-
-@example
-@group
-ifeq ($(strip $(foo)),)
-@var{text-if-empty}
-endif
-@end group
-@end example
-
-@noindent
-will evaluate @var{text-if-empty} even if the expansion of
-@code{$(foo)} contains whitespace characters.
-
-@item ifneq (@var{arg1}, @var{arg2})
-@itemx ifneq '@var{arg1}' '@var{arg2}'
-@itemx ifneq "@var{arg1}" "@var{arg2}"
-@itemx ifneq "@var{arg1}" '@var{arg2}'
-@itemx ifneq '@var{arg1}' "@var{arg2}"
-Expand all variable references in @var{arg1} and @var{arg2} and
-compare them.  If they are different, the @var{text-if-true} is
-effective; otherwise, the @var{text-if-false}, if any, is effective.
-
-@item ifdef @var{variable-name}
-The @code{ifdef} form takes the @emph{name} of a variable as its
-argument, not a reference to a variable.  If the value of that
-variable has a non-empty value, the @var{text-if-true} is effective;
-otherwise, the @var{text-if-false}, if any, is effective.  Variables
-that have never been defined have an empty value.  The text
-@var{variable-name} is expanded, so it could be a variable or function
-that expands to the name of a variable.  For example:
-
-@example
-bar = true
-foo = bar
-ifdef $(foo)
-frobozz = yes
-endif
-@end example
-
-The variable reference @code{$(foo)} is expanded, yielding @code{bar},
-which is considered to be the name of a variable.  The variable
-@code{bar} is not expanded, but its value is examined to determine if
-it is non-empty.
-
-Note that @code{ifdef} only tests whether a variable has a value.  It
-does not expand the variable to see if that value is nonempty.
-Consequently, tests using @code{ifdef} return true for all definitions
-except those like @code{foo =}.  To test for an empty value, use
-@w{@code{ifeq ($(foo),)}}.  For example,
-
-@example
-bar =
-foo = $(bar)
-ifdef foo
-frobozz = yes
-else
-frobozz = no
-endif
-@end example
-
-@noindent
-sets @samp{frobozz} to @samp{yes}, while:
-
-@example
-foo =
-ifdef foo
-frobozz = yes
-else
-frobozz = no
-endif
-@end example
-
-@noindent
-sets @samp{frobozz} to @samp{no}.
-
-@item ifndef @var{variable-name}
-If the variable @var{variable-name} has an empty value, the
-@var{text-if-true} is effective; otherwise, the @var{text-if-false},
-if any, is effective.  The rules for expansion and testing of
-@var{variable-name} are identical to the @code{ifdef} directive.
-@end table
-
-Extra spaces are allowed and ignored at the beginning of the
-conditional directive line, but a tab is not allowed.  (If the line
-begins with a tab, it will be considered part of a recipe for a rule.)
-Aside from this, extra spaces or tabs may be inserted with no effect
-anywhere except within the directive name or within an argument.  A
-comment starting with @samp{#} may appear at the end of the line.
-
-The other two directives that play a part in a conditional are @code{else}
-and @code{endif}.  Each of these directives is written as one word, with no
-arguments.  Extra spaces are allowed and ignored at the beginning of the
-line, and spaces or tabs at the end.  A comment starting with @samp{#} may
-appear at the end of the line.
-
-Conditionals affect which lines of the makefile @code{make} uses.  If
-the condition is true, @code{make} reads the lines of the
-@var{text-if-true} as part of the makefile; if the condition is false,
-@code{make} ignores those lines completely.  It follows that syntactic
-units of the makefile, such as rules, may safely be split across the
-beginning or the end of the conditional.@refill
-
-@code{make} evaluates conditionals when it reads a makefile.
-Consequently, you cannot use automatic variables in the tests of
-conditionals because they are not defined until recipes are run
-(@pxref{Automatic Variables}).
-
-To prevent intolerable confusion, it is not permitted to start a
-conditional in one makefile and end it in another.  However, you may
-write an @code{include} directive within a conditional, provided you do
-not attempt to terminate the conditional inside the included file.

-You can write a conditional that tests @code{make} command flags such as
-@samp{-t} by using the variable @code{MAKEFLAGS} together with the
-@code{findstring} function
-(@pxref{Text Functions, , Functions for String Substitution and Analysis}).
-This is useful when @code{touch} is not enough to make a file appear up
-to date.
-
-The @code{findstring} function determines whether one string appears as a
-substring of another.  If you want to test for the @samp{-t} flag,
-use @samp{t} as the first string and the value of @code{MAKEFLAGS} as
-the other.
-
-For example, here is how to arrange to use @samp{ranlib -t} to finish
-marking an archive file up to date:
-
-@example
-archive.a: @dots{}
-ifneq (,$(findstring t,$(MAKEFLAGS)))
-        +touch archive.a
-        +ranlib -t archive.a
-else
-        ranlib archive.a
-endif
-@end example
-
-@noindent
-The @samp{+} prefix marks those recipe lines as ``recursive'' so that
-they will be executed despite use of the @samp{-t} flag.

-@cindex functions, syntax of
-
-A function call resembles a variable reference.  It can appear
-anywhere a variable reference can appear, and it is expanded using the
-same rules as variable references.  A function call looks like this:
-
-@example
-$(@var{function} @var{arguments})
-@end example
-
-@noindent
-or like this:
-
-@example
-$@{@var{function} @var{arguments}@}
-@end example
-
-Here @var{function} is a function name; one of a short list of names
-that are part of @code{make}.  You can also essentially create your own
-functions by using the @code{call} built-in function.
-
-The @var{arguments} are the arguments of the function.  They are
-separated from the function name by one or more spaces or tabs, and if
-there is more than one argument, then they are separated by commas.
-Such whitespace and commas are not part of an argument's value.  The
-delimiters which you use to surround the function call, whether
-parentheses or braces, can appear in an argument only in matching pairs;
-the other kind of delimiters may appear singly.  If the arguments
-themselves contain other function calls or variable references, it is
-wisest to use the same kind of delimiters for all the references; write
-@w{@samp{$(subst a,b,$(x))}}, not @w{@samp{$(subst a,b,$@{x@})}}.  This
-is because it is clearer, and because only one type of delimiter is
-matched to find the end of the reference.
-
-The text written for each argument is processed by substitution of
-variables and function calls to produce the argument value, which
-is the text on which the function acts.  The substitution is done in the
-order in which the arguments appear.
-
-Commas and unmatched parentheses or braces cannot appear in the text of an
-argument as written; leading spaces cannot appear in the text of the first
-argument as written.  These characters can be put into the argument value
-by variable substitution.  First define variables @code{comma} and
-@code{space} whose values are isolated comma and space characters, then
-substitute these variables where such characters are wanted, like this:
-
-@example
-@group
-comma:= ,
-empty:=
-space:= $(empty) $(empty)
-foo:= a b c
-bar:= $(subst $(space),$(comma),$(foo))
-# @r{bar is now `a,b,c'.}
-@end group
-@end example
-
-@noindent
-Here the @code{subst} function replaces each space with a comma, through
-the value of @code{foo}, and substitutes the result.

-@cindex functions, for text
-
-Here are some functions that operate on strings:
-
-@table @code
-@item $(subst @var{from},@var{to},@var{text})
-@findex subst
-Performs a textual replacement on the text @var{text}: each occurrence
-of @var{from} is replaced by @var{to}.  The result is substituted for
-the function call.  For example,
-
-@example
-$(subst ee,EE,feet on the street)
-@end example
-
-produces the value @samp{fEEt on the strEEt}.
-
-@item $(patsubst @var{pattern},@var{replacement},@var{text})
-@findex patsubst
-Finds whitespace-separated words in @var{text} that match
-@var{pattern} and replaces them with @var{replacement}.  Here
-@var{pattern} may contain a @samp{%} which acts as a wildcard,
-matching any number of any characters within a word.  If
-@var{replacement} also contains a @samp{%}, the @samp{%} is replaced
-by the text that matched the @samp{%} in @var{pattern}.  Only the first
-@samp{%} in the @var{pattern} and @var{replacement} is treated this
-way; any subsequent @samp{%} is unchanged.@refill
-
-@cindex @code{%}, quoting in @code{patsubst}
-@cindex @code{%}, quoting with @code{\} (backslash)
-@cindex @code{\} (backslash), to quote @code{%}
-@cindex backslash (@code{\}), to quote @code{%}
-@cindex quoting @code{%}, in @code{patsubst}
-@samp{%} characters in @code{patsubst} function invocations can be
-quoted with preceding backslashes (@samp{\}).  Backslashes that would
-otherwise quote @samp{%} characters can be quoted with more backslashes.
-Backslashes that quote @samp{%} characters or other backslashes are
-removed from the pattern before it is compared file names or has a stem
-substituted into it.  Backslashes that are not in danger of quoting
-@samp{%} characters go unmolested.  For example, the pattern
-@file{the\%weird\\%pattern\\} has @samp{the%weird\} preceding the
-operative @samp{%} character, and @samp{pattern\\} following it.  The
-final two backslashes are left alone because they cannot affect any
-@samp{%} character.@refill
-
-Whitespace between words is folded into single space characters;
-leading and trailing whitespace is discarded.
-
-For example,
-
-@example
-$(patsubst %.c,%.o,x.c.c bar.c)
-@end example
-
-@noindent
-produces the value @samp{x.c.o bar.o}.
-
-Substitution references (@pxref{Substitution Refs, ,Substitution
-References}) are a simpler way to get the effect of the @code{patsubst}
-function:
-
-@example
-$(@var{var}:@var{pattern}=@var{replacement})
-@end example
-
-@noindent
-is equivalent to
-
-@example
-$(patsubst @var{pattern},@var{replacement},$(@var{var}))
-@end example
-
-The second shorthand simplifies one of the most common uses of
-@code{patsubst}: replacing the suffix at the end of file names.
-
-@example
-$(@var{var}:@var{suffix}=@var{replacement})
-@end example
-
-@noindent
-is equivalent to
-
-@example
-$(patsubst %@var{suffix},%@var{replacement},$(@var{var}))
-@end example
-
-@noindent
-For example, you might have a list of object files:
-
-@example
-objects = foo.o bar.o baz.o
-@end example
-
-@noindent
-To get the list of corresponding source files, you could simply write:
-
-@example
-$(objects:.o=.c)
-@end example
-
-@noindent
-instead of using the general form:
-
-@example
-$(patsubst %.o,%.c,$(objects))

-@item $(strip @var{string})
-@cindex stripping whitespace
-@cindex whitespace, stripping
-@cindex spaces, stripping
-@findex strip
-Removes leading and trailing whitespace from @var{string} and replaces
-each internal sequence of one or more whitespace characters with a
-single space.  Thus, @samp{$(strip a b  c )} results in @w{@samp{a b c}}.
-
-The function @code{strip} can be very useful when used in conjunction
-with conditionals.  When comparing something with the empty string
-@samp{} using @code{ifeq} or @code{ifneq}, you usually want a string of
-just whitespace to match the empty string (@pxref{Conditionals}).
-
-Thus, the following may fail to have the desired results:

-will be expanded.
-
-@table @code

-The @code{if} function provides support for conditional expansion in a

-conditionals such as @code{ifeq} (@pxref{Conditional Syntax, ,Syntax of
-Conditionals})).
-
-The first argument, @var{condition}, first has all preceding and
-trailing whitespace stripped, then is expanded.  If it expands to any
-non-empty string, then the condition is considered to be true.  If it
-expands to an empty string, the condition is considered to be false.
-
-If the condition is true then the second argument, @var{then-part}, is
-evaluated and this is used as the result of the evaluation of the entire
-@code{if} function.
-
-If the condition is false then the third argument, @var{else-part}, is
-evaluated and this is the result of the @code{if} function.  If there is
-no third argument, the @code{if} function evaluates to nothing (the
-empty string).
-
-Note that only one of the @var{then-part} or the @var{else-part} will be

-@section The @code{foreach} Function
-@findex foreach
-@cindex words, iterating over
-
-The @code{foreach} function is very different from other functions.  It
-causes one piece of text to be used repeatedly, each time with a different
-substitution performed on it.  It resembles the @code{for} command in the
-shell @code{sh} and the @code{foreach} command in the C-shell @code{csh}.
-
-The syntax of the @code{foreach} function is:
-
-@example
-$(foreach @var{var},@var{list},@var{text})
-@end example
-
-@noindent
-The first two arguments, @var{var} and @var{list}, are expanded before
-anything else is done; note that the last argument, @var{text}, is
-@strong{not} expanded at the same time.  Then for each word of the expanded
-value of @var{list}, the variable named by the expanded value of @var{var}
-is set to that word, and @var{text} is expanded.  Presumably @var{text}
-contains references to that variable, so its expansion will be different
-each time.
-
-The result is that @var{text} is expanded as many times as there are
-whitespace-separated words in @var{list}.  The multiple expansions of
-@var{text} are concatenated, with spaces between them, to make the result
-of @code{foreach}.
-
-This simple example sets the variable @samp{files} to the list of all files
-in the directories in the list @samp{dirs}:
-
-@example
-dirs := a b c d
-files := $(foreach dir,$(dirs),$(wildcard $(dir)/*))
-@end example
-
-Here @var{text} is @samp{$(wildcard $(dir)/*)}.  The first repetition
-finds the value @samp{a} for @code{dir}, so it produces the same result
-as @samp{$(wildcard a/*)}; the second repetition produces the result
-of @samp{$(wildcard b/*)}; and the third, that of @samp{$(wildcard c/*)}.
-
-This example has the same result (except for setting @samp{dirs}) as
-the following example:
-
-@example
-files := $(wildcard a/* b/* c/* d/*)
-@end example
-
-When @var{text} is complicated, you can improve readability by giving it
-a name, with an additional variable:
-
-@example
-find_files = $(wildcard $(dir)/*)
-dirs := a b c d
-files := $(foreach dir,$(dirs),$(find_files))
-@end example
-
-@noindent
-Here we use the variable @code{find_files} this way.  We use plain @samp{=}
-to define a recursively-expanding variable, so that its value contains an
-actual function call to be re-expanded under the control of @code{foreach};
-a simply-expanded variable would not do, since @code{wildcard} would be
-called only once at the time of defining @code{find_files}.
-
-The @code{foreach} function has no permanent effect on the variable
-@var{var}; its value and flavor after the @code{foreach} function call are
-the same as they were beforehand.  The other values which are taken from
-@var{list} are in effect only temporarily, during the execution of
-@code{foreach}.  The variable @var{var} is a simply-expanded variable
-during the execution of @code{foreach}.  If @var{var} was undefined
-before the @code{foreach} function call, it is undefined after the call.

-@findex file
-@cindex writing to a file
-@cindex file, writing to
-@cindex reading from a file
-@cindex file, reading from
-
-The @code{file} function allows the makefile to write to or read from
-a file.  Two modes of writing are supported: overwrite, where the text
-is written to the beginning of the file and any existing content is
-lost, and append, where the text is written to the end of the file,
-preserving the existing content.  In both cases the file is created if
-it does not exist.  It is a fatal error if the file cannot be opened
-for writing, or if the write operation fails.  The @code{file}
-function expands to the empty string when writing to a file.
-
-When reading from a file, the @code{file} function expands to the
-verbatim contents of the file, except that the final newline (if there
-is one) will be stripped.  Attempting to read from a non-existent file
-expands to the empty string.
-
-The syntax of the @code{file} function is:
-
-@example
-$(file @var{op} @var{filename}[,@var{text}])
-@end example
-
-When the @code{file} function is evaluated all its arguments are
-expanded first, then the file indicated by @var{filename} will be
-opened in the mode described by @var{op}.
-
-The operator @var{op} can be @code{>} to indicate the file will be
-overwritten with new content, @code{>>} to indicate the current
-contents of the file will be appended to, or @code{<} to indicate the
-contents of the file will be read in.  The @var{filename} specifies
-the file to be written to or read from.  There may optionally be
-whitespace between the operator and the file name.
-
-When reading files, it is an error to provide a @var{text} value.
-
-When writing files, @var{text} will be written to the file.  If
-@var{text} does not already end in a newline a final newline will be
-written (even if @var{text} is the empty string).  If the @var{text}
-argument is not given at all, nothing will be written.
-
-For example, the @code{file} function can be useful if your build
-system has a limited command line size and your recipe runs a command
-that can accept arguments from a file as well.  Many commands use the
-convention that an argument prefixed with an @code{@@} specifies a
-file containing more arguments.  Then you might write your recipe in
-this way:
-
-@example
-@group
-program: $(OBJECTS)
-        $(file >$@@.in,$^)
-        $(CMD) $(CMDFLAGS) @@$@@.in
-        @@rm $@@.in
-@end group
-@end example
-
-If the command required each argument to be on a separate line of the
-input file, you might write your recipe like this:
-
-@example
-@group
-program: $(OBJECTS)
-        $(file >$@@.in) $(foreach O,$^,$(file >>$@@.in,$O))

-@node Call Function, Value Function, File Function, Functions
-@section The @code{call} Function
-@findex call
-@cindex functions, user defined
-@cindex user defined functions
-
-The @code{call} function is unique in that it can be used to create new
-parameterized functions.  You can write a complex expression as the
-value of a variable, then use @code{call} to expand it with different
-values.
-
-The syntax of the @code{call} function is:
-
-@example
-$(call @var{variable},@var{param},@var{param},@dots{})
-@end example
-
-When @code{make} expands this function, it assigns each @var{param} to
-temporary variables @code{$(1)}, @code{$(2)}, etc.  The variable
-@code{$(0)} will contain @var{variable}.  There is no maximum number of
-parameter arguments.  There is no minimum, either, but it doesn't make
-sense to use @code{call} with no parameters.
-
-Then @var{variable} is expanded as a @code{make} variable in the context
-of these temporary assignments.  Thus, any reference to @code{$(1)} in
-the value of @var{variable} will resolve to the first @var{param} in the
-invocation of @code{call}.
-
-Note that @var{variable} is the @emph{name} of a variable, not a
-@emph{reference} to that variable.  Therefore you would not normally use
-a @samp{$} or parentheses when writing it.  (You can, however, use a
-variable reference in the name if you want the name not to be a
-constant.)
-
-If @var{variable} is the name of a built-in function, the built-in function
-is always invoked (even if a @code{make} variable by that name also
-exists).
-
-The @code{call} function expands the @var{param} arguments before
-assigning them to temporary variables.  This means that @var{variable}
-values containing references to built-in functions that have special
-expansion rules, like @code{foreach} or @code{if}, may not work as you
-expect.
-
-Some examples may make this clearer.
-
-This macro simply reverses its arguments:
-
-@smallexample
-reverse = $(2) $(1)
-
-foo = $(call reverse,a,b)
-@end smallexample
-
-@noindent
-Here @var{foo} will contain @samp{b a}.
-
-This one is slightly more interesting: it defines a macro to search for
-the first instance of a program in @code{PATH}:
-
-@smallexample
-pathsearch = $(firstword $(wildcard $(addsuffix /$(1),$(subst :, ,$(PATH)))))
-
-LS := $(call pathsearch,ls)
-@end smallexample
-
-@noindent
-Now the variable LS contains @code{/bin/ls} or similar.
-
-The @code{call} function can be nested.  Each recursive invocation gets
-its own local values for @code{$(1)}, etc.@: that mask the values of
-higher-level @code{call}.  For example, here is an implementation of a
-@dfn{map} function:
-
-@smallexample
-map = $(foreach a,$(2),$(call $(1),$(a)))
-@end smallexample
-
-Now you can @var{map} a function that normally takes only one argument,
-such as @code{origin}, to multiple values in one step:
-
-@smallexample
-o = $(call map,origin,o map MAKE)
-@end smallexample
-
-and end up with @var{o} containing something like @samp{file file default}.
-
-A final caution: be careful when adding whitespace to the arguments to
-@code{call}.  As with other functions, any whitespace contained in the
-second and subsequent arguments is kept; this can cause strange
-effects.  It's generally safest to remove all extraneous whitespace when
-providing parameters to @code{call}.

-@findex value
-@cindex variables, unexpanded value
-
-The @code{value} function provides a way for you to use the value of a
-variable @emph{without} having it expanded.  Please note that this
-does not undo expansions which have already occurred; for example if
-you create a simply expanded variable its value is expanded during the
-definition; in that case the @code{value} function will return the
-same result as using the variable directly.
-
-The syntax of the @code{value} function is:
-
-@example
-$(value @var{variable})
-@end example
-
-Note that @var{variable} is the @emph{name} of a variable, not a
-@emph{reference} to that variable.  Therefore you would not normally
-use a @samp{$} or parentheses when writing it.  (You can, however, use
-a variable reference in the name if you want the name not to be a
-constant.)
-
-The result of this function is a string containing the value of
-@var{variable}, without any expansion occurring.  For example, in this
-makefile:
-
-@example
-@group
-FOO = $PATH
-
-all:
-        @@echo $(FOO)
-        @@echo $(value FOO)
-@end group
-@end example
-
-@noindent
-The first output line would be @code{ATH}, since the ``$P'' would be
-expanded as a @code{make} variable, while the second output line would
-be the current value of your @code{$PATH} environment variable, since
-the @code{value} function avoided the expansion.

-@cindex makefile syntax, evaluating
-
-The @code{eval} function is very special: it allows you to define new
-makefile constructs that are not constant; which are the result of
-evaluating other variables and functions.  The argument to the
-@code{eval} function is expanded, then the results of that expansion
-are parsed as makefile syntax.  The expanded results can define new
-@code{make} variables, targets, implicit or explicit rules, etc.
-
-The result of the @code{eval} function is always the empty string;
-thus, it can be placed virtually anywhere in a makefile without
-causing syntax errors.
-
-It's important to realize that the @code{eval} argument is expanded
-@emph{twice}; first by the @code{eval} function, then the results of
-that expansion are expanded again when they are parsed as makefile
-syntax.  This means you may need to provide extra levels of escaping
-for ``$'' characters when using @code{eval}.  The @code{value}
-function (@pxref{Value Function}) can sometimes be useful in these
-situations, to circumvent unwanted expansions.
-
-Here is an example of how @code{eval} can be used; this example
-combines a number of concepts and other functions.  Although it might
-seem overly complex to use @code{eval} in this example, rather than
-just writing out the rules, consider two things: first, the template
-definition (in @code{PROGRAM_template}) could need to be much more
-complex than it is here; and second, you might put the complex,
-``generic'' part of this example into another makefile, then include
-it in all the individual makefiles.  Now your individual makefiles are
-quite straightforward.

-@cindex @code{--file}
-@cindex @code{--makefile}
-@cindex @code{-f}
-
-The way to specify the name of the makefile is with the @samp{-f} or
-@samp{--file} option (@samp{--makefile} also works).  For example,
-@samp{-f altmake} says to use the file @file{altmake} as the makefile.
-
-If you use the @samp{-f} flag several times and follow each @samp{-f}
-with an argument, all the specified files are used jointly as
-makefiles.
-
-If you do not use the @samp{-f} or @samp{--file} flag, the default is
-to try @file{GNUmakefile}, @file{makefile}, and @file{Makefile}, in
-that order, and use the first of these three which exists or can be made
-(@pxref{Makefiles, ,Writing Makefiles}).@refill
-
-@node Goals, Instead of Execution, Makefile Arguments, Running
-@section Arguments to Specify the Goals
-@cindex goal, how to specify
-
-The @dfn{goals} are the targets that @code{make} should strive ultimately
-to update.  Other targets are updated as well if they appear as
-prerequisites of goals, or prerequisites of prerequisites of goals, etc.
-
-By default, the goal is the first target in the makefile (not counting
-targets that start with a period).  Therefore, makefiles are usually
-written so that the first target is for compiling the entire program or
-programs they describe.  If the first rule in the makefile has several
-targets, only the first target in the rule becomes the default goal, not
-the whole list.  You can manage the selection of the default goal from
-within your makefile using the @code{.DEFAULT_GOAL} variable
-(@pxref{Special Variables, , Other Special Variables}).
-
-You can also specify a different goal or goals with command line
-arguments to @code{make}.  Use the name of the goal as an argument.
-If you specify several goals, @code{make} processes each of them in
-turn, in the order you name them.
-
-Any target in the makefile may be specified as a goal (unless it
-starts with @samp{-} or contains an @samp{=}, in which case it will be
-parsed as a switch or variable definition, respectively).  Even
-targets not in the makefile may be specified, if @code{make} can find
-implicit rules that say how to make them.
-
-@vindex MAKECMDGOALS
-@code{Make} will set the special variable @code{MAKECMDGOALS} to the
-list of goals you specified on the command line.  If no goals were given
-on the command line, this variable is empty.  Note that this variable
-should be used only in special circumstances.
-
-An example of appropriate use is to avoid including @file{.d} files
-during @code{clean} rules (@pxref{Automatic Prerequisites}), so
-@code{make} won't create them only to immediately remove them
-again:@refill
-
-@example
-@group
-sources = foo.c bar.c
-
-ifneq ($(MAKECMDGOALS),clean)
-include $(sources:.c=.d)
-endif
-@end group
-@end example
-
-One use of specifying a goal is if you want to compile only a part of
-the program, or only one of several programs.  Specify as a goal each
-file that you wish to remake.  For example, consider a directory containing
-several programs, with a makefile that starts like this:
-
-@example
-.PHONY: all
-all: size nm ld ar as
-@end example
-
-If you are working on the program @code{size}, you might want to say
-@w{@samp{make size}} so that only the files of that program are recompiled.
-
-Another use of specifying a goal is to make files that are not normally
-made.  For example, there may be a file of debugging output, or a
-version of the program that is compiled specially for testing, which has
-a rule in the makefile but is not a prerequisite of the default goal.
-
-Another use of specifying a goal is to run the recipe associated with
-a phony target (@pxref{Phony Targets}) or empty target (@pxref{Empty
-Targets, ,Empty Target Files to Record Events}).  Many makefiles contain
-a phony target named @file{clean} which deletes everything except source
-files.  Naturally, this is done only if you request it explicitly with
-@w{@samp{make clean}}.  Following is a list of typical phony and empty
-target names.  @xref{Standard Targets}, for a detailed list of all the
-standard target names which GNU software packages use.
-
-@table @file
-@item all
-@cindex @code{all} @r{(standard target)}
-Make all the top-level targets the makefile knows about.
-
-@item clean
-@cindex @code{clean} @r{(standard target)}
-Delete all files that are normally created by running @code{make}.
-
-@item mostlyclean
-@cindex @code{mostlyclean} @r{(standard target)}
-Like @samp{clean}, but may refrain from deleting a few files that people
-normally don't want to recompile.  For example, the @samp{mostlyclean}
-target for GCC does not delete @file{libgcc.a}, because recompiling it
-is rarely necessary and takes a lot of time.
-
-@item distclean
-@cindex @code{distclean} @r{(standard target)}
-@itemx realclean
-@cindex @code{realclean} @r{(standard target)}
-@itemx clobber
-@cindex @code{clobber} @r{(standard target)}
-Any of these targets might be defined to delete @emph{more} files than
-@samp{clean} does.  For example, this would delete configuration files
-or links that you would normally create as preparation for compilation,
-even if the makefile itself cannot create these files.
-
-@item install
-@cindex @code{install} @r{(standard target)}
-Copy the executable file into a directory that users typically search
-for commands; copy any auxiliary files that the executable uses into
-the directories where it will look for them.
-
-@item print
-@cindex @code{print} @r{(standard target)}
-Print listings of the source files that have changed.
-
-@item tar
-@cindex @code{tar} @r{(standard target)}
-Create a tar file of the source files.
-
-@item shar
-@cindex @code{shar} @r{(standard target)}
-Create a shell archive (shar file) of the source files.
-
-@item dist
-@cindex @code{dist} @r{(standard target)}
-Create a distribution file of the source files.  This might
-be a tar file, or a shar file, or a compressed version of one of the
-above, or even more than one of the above.
-
-@item TAGS
-@cindex @code{TAGS} @r{(standard target)}
-Update a tags table for this program.
-

-
-Sometimes you may have changed a source file but you do not want to
-recompile all the files that depend on it.  For example, suppose you add
-a macro or a declaration to a header file that many other files depend
-on.  Being conservative, @code{make} assumes that any change in the
-header file requires recompilation of all dependent files, but you know
-that they do not need to be recompiled and you would rather not waste
-the time waiting for them to compile.
-
-If you anticipate the problem before changing the header file, you can
-use the @samp{-t} flag.  This flag tells @code{make} not to run the
-recipes in the rules, but rather to mark the target up to date by
-changing its last-modification date.  You would follow this procedure:
-
-@enumerate
-@item
-Use the command @samp{make} to recompile the source files that really
-need recompilation, ensuring that the object files are up-to-date
-before you begin.
-
-@item
-Make the changes in the header files.
-
-@item
-Use the command @samp{make -t} to mark all the object files as
-up to date.  The next time you run @code{make}, the changes in the
-header files will not cause any recompilation.
-@end enumerate
-
-If you have already changed the header file at a time when some files
-do need recompilation, it is too late to do this.  Instead, you can
-use the @w{@samp{-o @var{file}}} flag, which marks a specified file as
-``old'' (@pxref{Options Summary, ,Summary of Options}).  This means
-that the file itself will not be remade, and nothing else will be
-remade on its account.  Follow this procedure:
-
-@enumerate
-@item
-Recompile the source files that need compilation for reasons independent
-of the particular header file, with @samp{make -o @var{headerfile}}.
-If several header files are involved, use a separate @samp{-o} option
-for each header file.

-Touch all the object files with @samp{make -t}.

-@section Overriding Variables
-@cindex overriding variables with arguments
-@cindex variables, overriding with arguments
-@cindex command line variables
-@cindex variables, command line
-
-An argument that contains @samp{=} specifies the value of a variable:
-@samp{@var{v}=@var{x}} sets the value of the variable @var{v} to @var{x}.
-If you specify a value in this way, all ordinary assignments of the same
-variable in the makefile are ignored; we say they have been
-@dfn{overridden} by the command line argument.
-
-The most common way to use this facility is to pass extra flags to
-compilers.  For example, in a properly written makefile, the variable
-@code{CFLAGS} is included in each recipe that runs the C compiler, so a
-file @file{foo.c} would be compiled something like this:
-
-@example
-cc -c $(CFLAGS) foo.c
-@end example
-
-Thus, whatever value you set for @code{CFLAGS} affects each compilation
-that occurs.  The makefile probably specifies the usual value for
-@code{CFLAGS}, like this:
-
-@example
-CFLAGS=-g
-@end example
-
-Each time you run @code{make}, you can override this value if you
-wish.  For example, if you say @samp{make CFLAGS='-g -O'}, each C
-compilation will be done with @samp{cc -c -g -O}.  (This also
-illustrates how you can use quoting in the shell to enclose spaces and
-other special characters in the value of a variable when you override
-it.)
-
-The variable @code{CFLAGS} is only one of many standard variables that
-exist just so that you can change them this way.  @xref{Implicit
-Variables, , Variables Used by Implicit Rules}, for a complete list.
-
-You can also program the makefile to look at additional variables of your
-own, giving the user the ability to control other aspects of how the
-makefile works by changing the variables.
-
-When you override a variable with a command line argument, you can
-define either a recursively-expanded variable or a simply-expanded
-variable.  The examples shown above make a recursively-expanded
-variable; to make a simply-expanded variable, write @samp{:=} or
-@samp{::=} instead of @samp{=}.  But, unless you want to include a
-variable reference or function call in the @emph{value} that you
-specify, it makes no difference which kind of variable you create.
-
-There is one way that the makefile can change a variable that you have
-overridden.  This is to use the @code{override} directive, which is a line
-that looks like this: @samp{override @var{variable} = @var{value}}
-(@pxref{Override Directive, ,The @code{override} Directive}).

-
-Normally, when an error happens in executing a shell command, @code{make}
-gives up immediately, returning a nonzero status.  No further recipes are
-executed for any target.  The error implies that the goal cannot be
-correctly remade, and @code{make} reports this as soon as it knows.
-
-When you are compiling a program that you have just changed, this is not
-what you want.  Instead, you would rather that @code{make} try compiling
-every file that can be tried, to show you as many compilation errors
-as possible.
-
-@cindex @code{-k}
-@cindex @code{--keep-going}
-On these occasions, you should use the @samp{-k} or
-@samp{--keep-going} flag.  This tells @code{make} to continue to
-consider the other prerequisites of the pending targets, remaking them
-if necessary, before it gives up and returns nonzero status.  For
-example, after an error in compiling one object file, @samp{make -k}
-will continue compiling other object files even though it already
-knows that linking them will be impossible.  In addition to continuing
-after failed shell commands, @samp{make -k} will continue as much as
-possible after discovering that it does not know how to make a target
-or prerequisite file.  This will always cause an error message, but
-without @samp{-k}, it is a fatal error (@pxref{Options Summary,
-,Summary of Options}).@refill
-
-The usual behavior of @code{make} assumes that your purpose is to get the
-goals up to date; once @code{make} learns that this is impossible, it might
-as well report the failure immediately.  The @samp{-k} flag says that the
-real purpose is to test as much as possible of the changes made in the
-program, perhaps to find several independent problems so that you can
-correct them all before the next attempt to compile.  This is why Emacs'
-@kbd{M-x compile} command passes the @samp{-k} flag by default.

-Certain standard ways of remaking target files are used very often.  For
-example, one customary way to make an object file is from a C source file
-using the C compiler, @code{cc}.
-
-@dfn{Implicit rules} tell @code{make} how to use customary techniques so
-that you do not have to specify them in detail when you want to use
-them.  For example, there is an implicit rule for C compilation.  File
-names determine which implicit rules are run.  For example, C
-compilation typically takes a @file{.c} file and makes a @file{.o} file.
-So @code{make} applies the implicit rule for C compilation when it sees
-this combination of file name endings.@refill
-
-A chain of implicit rules can apply in sequence; for example, @code{make}
-will remake a @file{.o} file from a @file{.y} file by way of a @file{.c} file.
-@iftex
-@xref{Chained Rules, ,Chains of Implicit Rules}.
-@end iftex
-
-The built-in implicit rules use several variables in their recipes so
-that, by changing the values of the variables, you can change the way the
-implicit rule works.  For example, the variable @code{CFLAGS} controls the
-flags given to the C compiler by the implicit rule for C compilation.

-@section Using Implicit Rules
-@cindex implicit rule, how to use
-@cindex rule, implicit, how to use
-
-To allow @code{make} to find a customary method for updating a target
-file, all you have to do is refrain from specifying recipes yourself.
-Either write a rule with no recipe, or don't write a rule at all.
-Then @code{make} will figure out which implicit rule to use based on
-which kind of source file exists or can be made.
-
-For example, suppose the makefile looks like this:
-
-@example
-foo : foo.o bar.o
-        cc -o foo foo.o bar.o $(CFLAGS) $(LDFLAGS)
-@end example
-
-@noindent
-Because you mention @file{foo.o} but do not give a rule for it, @code{make}
-will automatically look for an implicit rule that tells how to update it.
-This happens whether or not the file @file{foo.o} currently exists.
-
-If an implicit rule is found, it can supply both a recipe and one or
-more prerequisites (the source files).  You would want to write a rule
-for @file{foo.o} with no recipe if you need to specify additional
-prerequisites, such as header files, that the implicit rule cannot
-supply.
-
-Each implicit rule has a target pattern and prerequisite patterns.  There may
-be many implicit rules with the same target pattern.  For example, numerous
-rules make @samp{.o} files: one, from a @samp{.c} file with the C compiler;
-another, from a @samp{.p} file with the Pascal compiler; and so on.  The rule
-that actually applies is the one whose prerequisites exist or can be made.
-So, if you have a file @file{foo.c}, @code{make} will run the C compiler;
-otherwise, if you have a file @file{foo.p}, @code{make} will run the Pascal
-compiler; and so on.
-
-Of course, when you write the makefile, you know which implicit rule you
-want @code{make} to use, and you know it will choose that one because you
-know which possible prerequisite files are supposed to exist.
-@xref{Catalogue of Rules, ,Catalogue of Built-In Rules},
-for a catalogue of all the predefined implicit rules.
-
-Above, we said an implicit rule applies if the required prerequisites ``exist
-or can be made''.  A file ``can be made'' if it is mentioned explicitly in
-the makefile as a target or a prerequisite, or if an implicit rule can be
-recursively found for how to make it.  When an implicit prerequisite is the
-result of another implicit rule, we say that @dfn{chaining} is occurring.
-@xref{Chained Rules, ,Chains of Implicit Rules}.
-
-In general, @code{make} searches for an implicit rule for each target, and
-for each double-colon rule, that has no recipe.  A file that is mentioned
-only as a prerequisite is considered a target whose rule specifies nothing,
-so implicit rule search happens for it.  @xref{Implicit Rule Search, ,Implicit Rule Search Algorithm}, for the
-details of how the search is done.
-
-Note that explicit prerequisites do not influence implicit rule search.
-For example, consider this explicit rule:
-
-@example
-foo.o: foo.p
-@end example
-
-@noindent
-The prerequisite on @file{foo.p} does not necessarily mean that
-@code{make} will remake @file{foo.o} according to the implicit rule to
-make an object file, a @file{.o} file, from a Pascal source file, a
-@file{.p} file.  For example, if @file{foo.c} also exists, the implicit
-rule to make an object file from a C source file is used instead,
-because it appears before the Pascal rule in the list of predefined
-implicit rules (@pxref{Catalogue of Rules, , Catalogue of Built-In
-Rules}).
-
-If you do not want an implicit rule to be used for a target that has no
-recipe, you can give that target an empty recipe by writing a semicolon
-(@pxref{Empty Recipes, ,Defining Empty Recipes}).
-
-@node Catalogue of Rules, Implicit Variables, Using Implicit, Implicit Rules
-@section Catalogue of Built-In Rules
-@cindex implicit rule, predefined
-@cindex rule, implicit, predefined
-
-Here is a catalogue of predefined implicit rules which are always
-available unless the makefile explicitly overrides or cancels them.
-@xref{Canceling Rules, ,Canceling Implicit Rules}, for information on
-canceling or overriding an implicit rule.  The @samp{-r} or
-@samp{--no-builtin-rules} option cancels all predefined rules.
-
-This manual only documents the default rules available on POSIX-based
-operating systems.  Other operating systems, such as VMS, Windows,
-OS/2, etc. may have different sets of default rules.  To see the full
-list of default rules and variables available in your version of GNU
-@code{make}, run @samp{make -p} in a directory with no makefile.
-
-Not all of these rules will always be defined, even when the @samp{-r}
-option is not given.  Many of the predefined implicit rules are
-implemented in @code{make} as suffix rules, so which ones will be
-defined depends on the @dfn{suffix list} (the list of prerequisites of
-the special target @code{.SUFFIXES}).  The default suffix list is:
-@code{.out}, @code{.a}, @code{.ln}, @code{.o}, @code{.c}, @code{.cc},
-@code{.C}, @code{.cpp}, @code{.p}, @code{.f}, @code{.F}, @code{.m},

-whose prerequisites have one of these suffixes are actually suffix
-rules.  If you modify the suffix list, the only predefined suffix
-rules in effect will be those named by one or two of the suffixes that
-are on the list you specify; rules whose suffixes fail to be on the
-list are disabled.  @xref{Suffix Rules, ,Old-Fashioned Suffix Rules},

-This rule does the right thing for a simple program with only one

-

-@end group
-@end example
-
-@noindent
-In more complicated cases, such as when there is no object file whose
-name derives from the executable file name, you must write an explicit
-recipe for linking.
-
-Each kind of file automatically made into @samp{.o} object files will
-be automatically linked by using the compiler (@samp{$(CC)},

-@end table
-
-Usually, you want to change only the variables listed in the table
-above, which are documented in the following section.
-
-However, the recipes in built-in implicit rules actually use
-variables such as @code{COMPILE.c}, @code{LINK.p}, and
-@code{PREPROCESS.S}, whose values contain the recipes listed above.
-
-@code{make} follows the convention that the rule to compile a
-@file{.@var{x}} source file uses the variable @code{COMPILE.@var{x}}.
-Similarly, the rule to produce an executable from a @file{.@var{x}}
-file uses @code{LINK.@var{x}}; and the rule to preprocess a
-@file{.@var{x}} file uses @code{PREPROCESS.@var{x}}.
-
-@vindex OUTPUT_OPTION
-Every rule that produces an object file uses the variable
-@code{OUTPUT_OPTION}.  @code{make} defines this variable either to
-contain @samp{-o $@@}, or to be empty, depending on a compile-time
-option.  You need the @samp{-o} option to ensure that the output goes
-into the right file when the source file is in a different directory,
-as when using @code{VPATH} (@pxref{Directory Search}).  However,
-compilers on some systems do not accept a @samp{-o} switch for object
-files.  If you use such a system, and use @code{VPATH}, some
-compilations will put their output in the wrong place.
-A possible workaround for this problem is to give @code{OUTPUT_OPTION}
-the value @w{@samp{; mv $*.o $@@}}.

-@section Variables Used by Implicit Rules
-@cindex flags for compilers
-
-The recipes in built-in implicit rules make liberal use of certain
-predefined variables.  You can alter the values of these variables in
-the makefile, with arguments to @code{make}, or in the environment to
-alter how the implicit rules work without redefining the rules
-themselves.  You can cancel all variables used by implicit rules with
-the @samp{-R} or @samp{--no-builtin-variables} option.
-
-For example, the recipe used to compile a C source file actually says
-@samp{$(CC) -c $(CFLAGS) $(CPPFLAGS)}.  The default values of the variables
-used are @samp{cc} and nothing, resulting in the command @samp{cc -c}.  By
-redefining @samp{CC} to @samp{ncc}, you could cause @samp{ncc} to be
-used for all C compilations performed by the implicit rule.  By redefining
-@samp{CFLAGS} to be @samp{-g}, you could pass the @samp{-g} option to
-each compilation.  @emph{All} implicit rules that do C compilation use
-@samp{$(CC)} to get the program name for the compiler and @emph{all}
-include @samp{$(CFLAGS)} among the arguments given to the compiler.@refill
-
-The variables used in implicit rules fall into two classes: those that are
-names of programs (like @code{CC}) and those that contain arguments for the
-programs (like @code{CFLAGS}).  (The ``name of a program'' may also contain
-some command arguments, but it must start with an actual executable program
-name.)  If a variable value contains more than one argument, separate them
-with spaces.
-
-The following tables describe of some of the more commonly-used predefined
-variables.  This list is not exhaustive, and the default values shown here may
-not be what @code{make} selects for your environment.  To see the
-complete list of predefined variables for your instance of GNU @code{make} you
-can run @samp{make -p} in a directory with no makefiles.

-a file @file{@var{n}.o} could be made from @file{@var{n}.y} by running
-first Yacc and then @code{cc}.  Such a sequence is called a @dfn{chain}.
-
-If the file @file{@var{n}.c} exists, or is mentioned in the makefile, no
-special searching is required: @code{make} finds that the object file can
-be made by C compilation from @file{@var{n}.c}; later on, when considering
-how to make @file{@var{n}.c}, the rule for running Yacc is
-used.  Ultimately both @file{@var{n}.c} and @file{@var{n}.o} are
-updated.@refill
-
-@cindex intermediate files
-@cindex files, intermediate
-However, even if @file{@var{n}.c} does not exist and is not mentioned,
-@code{make} knows how to envision it as the missing link between
-@file{@var{n}.o} and @file{@var{n}.y}!  In this case, @file{@var{n}.c} is
-called an @dfn{intermediate file}.  Once @code{make} has decided to use the
-intermediate file, it is entered in the data base as if it had been
-mentioned in the makefile, along with the implicit rule that says how to
-create it.@refill
-
-Intermediate files are remade using their rules just like all other
-files.  But intermediate files are treated differently in two ways.
-
-The first difference is what happens if the intermediate file does not
-exist.  If an ordinary file @var{b} does not exist, and @code{make}
-considers a target that depends on @var{b}, it invariably creates
-@var{b} and then updates the target from @var{b}.  But if @var{b} is an
-intermediate file, then @code{make} can leave well enough alone.  It
-won't bother updating @var{b}, or the ultimate target, unless some
-prerequisite of @var{b} is newer than that target or there is some other
-reason to update that target.
-
-The second difference is that if @code{make} @emph{does} create @var{b}
-in order to update something else, it deletes @var{b} later on after it
-is no longer needed.  Therefore, an intermediate file which did not
-exist before @code{make} also does not exist after @code{make}.
-@code{make} reports the deletion to you by printing a @samp{rm -f}
-command showing which file it is deleting.
-
-Ordinarily, a file cannot be intermediate if it is mentioned in the
-makefile as a target or prerequisite.  However, you can explicitly mark a
-file as intermediate by listing it as a prerequisite of the special target
-@code{.INTERMEDIATE}.  This takes effect even if the file is mentioned
-explicitly in some other way.
-
-@cindex intermediate files, preserving
-@cindex preserving intermediate files
-@cindex secondary files
-You can prevent automatic deletion of an intermediate file by marking it
-as a @dfn{secondary} file.  To do this, list it as a prerequisite of the
-special target @code{.SECONDARY}.  When a file is secondary, @code{make}
-will not create the file merely because it does not already exist, but
-@code{make} does not automatically delete the file.  Marking a file as
-secondary also marks it as intermediate.
-
-You can list the target pattern of an implicit rule (such as @samp{%.o})
-as a prerequisite of the special target @code{.PRECIOUS} to preserve
-intermediate files made by implicit rules whose target patterns match
-that file's name; see @ref{Interrupts}.@refill
-@cindex preserving with @code{.PRECIOUS}
-@cindex @code{.PRECIOUS} intermediate files
-
-A chain can involve more than two implicit rules.  For example, it is
-possible to make a file @file{foo} from @file{RCS/foo.y,v} by running RCS,
-Yacc and @code{cc}.  Then both @file{foo.y} and @file{foo.c} are
-intermediate files that are deleted at the end.@refill
-
-No single implicit rule can appear more than once in a chain.  This means
-that @code{make} will not even consider such a ridiculous thing as making
-@file{foo} from @file{foo.o.o} by running the linker twice.  This
-constraint has the added benefit of preventing any infinite loop in the
-search for an implicit rule chain.
-
-There are some special implicit rules to optimize certain cases that would
-otherwise be handled by rule chains.  For example, making @file{foo} from
-@file{foo.c} could be handled by compiling and linking with separate
-chained rules, using @file{foo.o} as an intermediate file.  But what
-actually happens is that a special rule for this case does the compilation
-and linking with a single @code{cc} command.  The optimized rule is used in
-preference to the step-by-step chain because it comes earlier in the
-ordering of rules.
-
-Finally, for performance reasons @code{make} will not consider non-terminal
-match-anything rules (i.e., @samp{%:}) when searching for a rule to
-build a prerequisite of an implicit rule (@pxref{Match-Anything Rules}).
-
-@node Pattern Rules, Last Resort, Chained Rules, Implicit Rules
-@section Defining and Redefining Pattern Rules
-
-You define an implicit rule by writing a @dfn{pattern rule}.  A pattern
-rule looks like an ordinary rule, except that its target contains the
-character @samp{%} (exactly one of them).  The target is considered a
-pattern for matching file names; the @samp{%} can match any nonempty
-substring, while other characters match only themselves.  The prerequisites
-likewise use @samp{%} to show how their names relate to the target name.
-
-Thus, a pattern rule @samp{%.o : %.c} says how to make any file
-@file{@var{stem}.o} from another file @file{@var{stem}.c}.@refill
-
-Note that expansion using @samp{%} in pattern rules occurs

-
-A pattern rule contains the character @samp{%} (exactly one of them)
-in the target; otherwise, it looks exactly like an ordinary rule.  The
-target is a pattern for matching file names; the @samp{%} matches any
-nonempty substring, while other characters match only themselves.
-@cindex target pattern, implicit
-@cindex @code{%}, in pattern rules
-
-For example, @samp{%.c} as a pattern matches any file name that ends in
-@samp{.c}.  @samp{s.%.c} as a pattern matches any file name that starts
-with @samp{s.}, ends in @samp{.c} and is at least five characters long.
-(There must be at least one character to match the @samp{%}.)  The substring
-that the @samp{%} matches is called the @dfn{stem}.@refill
-
-@samp{%} in a prerequisite of a pattern rule stands for the same stem
-that was matched by the @samp{%} in the target.  In order for the
-pattern rule to apply, its target pattern must match the file name
-under consideration and all of its prerequisites (after pattern
-substitution) must name files that exist or can be made.  These files
-become prerequisites of the target.
-@cindex prerequisite pattern, implicit
-
-Thus, a rule of the form
-
-@example
-%.o : %.c ; @var{recipe}@dots{}
-@end example
-
-@noindent
-specifies how to make a file @file{@var{n}.o}, with another file
-@file{@var{n}.c} as its prerequisite, provided that @file{@var{n}.c}
-exists or can be made.
-
-There may also be prerequisites that do not use @samp{%}; such a prerequisite
-attaches to every file made by this pattern rule.  These unvarying
-prerequisites are useful occasionally.
-
-A pattern rule need not have any prerequisites that contain @samp{%}, or
-in fact any prerequisites at all.  Such a rule is effectively a general
-wildcard.  It provides a way to make any file that matches the target
-pattern.  @xref{Last Resort}.
-
-More than one pattern rule may match a target.  In this case
-@code{make} will choose the ``best fit'' rule.  @xref{Pattern Match,

-@example
-%.o : %.c
-        $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@@

-

-defines a rule that can make any file @file{@var{x}.o} from
-@file{@var{x}.c}.  The recipe uses the automatic variables @samp{$@@} and
-@samp{$<} to substitute the names of the target file and the source file
-in each case where the rule applies (@pxref{Automatic Variables}).@refill
-
-Here is a second built-in rule:
-
-@example
-% :: RCS/%,v
-        $(CO) $(COFLAGS) $<
-@end example
-
-@noindent
-defines a rule that can make any file @file{@var{x}} whatsoever from a
-corresponding file @file{@var{x},v} in the sub-directory @file{RCS}.  Since
-the target is @samp{%}, this rule will apply to any file whatever, provided
-the appropriate prerequisite file exists.  The double colon makes the rule
-@dfn{terminal}, which means that its prerequisite may not be an intermediate
-file (@pxref{Match-Anything Rules, ,Match-Anything Pattern Rules}).@refill
-
-@need 500
-This pattern rule has two targets:
-
-@example
-@group
-%.tab.c %.tab.h: %.y
-        bison -d $<
-@end group
-@end example
-
-@noindent
-@c The following paragraph is rewritten to avoid overfull hboxes
-This tells @code{make} that the recipe @samp{bison -d @var{x}.y} will
-make both @file{@var{x}.tab.c} and @file{@var{x}.tab.h}.  If the file
-@file{foo} depends on the files @file{parse.tab.o} and @file{scan.o}
-and the file @file{scan.o} depends on the file @file{parse.tab.h},
-when @file{parse.y} is changed, the recipe @samp{bison -d parse.y}
-will be executed only once, and the prerequisites of both
-@file{parse.tab.o} and @file{scan.o} will be satisfied.  (Presumably
-the file @file{parse.tab.o} will be recompiled from @file{parse.tab.c}
-and the file @file{scan.o} from @file{scan.c}, while @file{foo} is
-linked from @file{parse.tab.o}, @file{scan.o}, and its other
-prerequisites, and it will execute happily ever after.)@refill

-
-Suppose you are writing a pattern rule to compile a @samp{.c} file into a
-@samp{.o} file: how do you write the @samp{cc} command so that it operates
-on the right source file name?  You cannot write the name in the recipe,
-because the name is different each time the implicit rule is applied.
-
-What you do is use a special feature of @code{make}, the @dfn{automatic
-variables}.  These variables have values computed afresh for each rule that
-is executed, based on the target and prerequisites of the rule.  In this
-example, you would use @samp{$@@} for the object file name and @samp{$<}
-for the source file name.

-@cindex automatic variables in prerequisites
-@cindex prerequisites, and automatic variables
-It's very important that you recognize the limited scope in which
-automatic variable values are available: they only have values within
-the recipe.  In particular, you cannot use them anywhere
-within the target list of a rule; they have no value there and will
-expand to the empty string.  Also, they cannot be accessed directly
-within the prerequisite list of a rule.  A common mistake is
-attempting to use @code{$@@} within the prerequisites list; this will
-not work.  However, there is a special feature of GNU @code{make},
-secondary expansion (@pxref{Secondary Expansion}), which will allow
-automatic variable values to be used in prerequisite lists.

-
-@table @code
-@vindex $@@
-@vindex @@ @r{(automatic variable)}
-@item $@@
-The file name of the target of the rule.  If the target is an archive
-member, then @samp{$@@} is the name of the archive file.  In a pattern
-rule that has multiple targets (@pxref{Pattern Intro, ,Introduction to
-Pattern Rules}), @samp{$@@} is the name of whichever target caused the
-rule's recipe to be run.
-
-@vindex $%
-@vindex % @r{(automatic variable)}

-using @samp{$*} except in implicit rules or static pattern rules.@refill
-
-If the target name in an explicit rule does not end with a recognized
-suffix, @samp{$*} is set to the empty string for that rule.
-@end table
-
-@samp{$?} is useful even in explicit rules when you wish to operate on only
-the prerequisites that have changed.  For example, suppose that an archive
-named @file{lib} is supposed to contain copies of several object files.
-This rule copies just the changed object files into the archive:
-
-@example
-@group
-lib: foo.o bar.o lose.o win.o
-        ar r lib $?
-@end group
-@end example
-
-Of the variables listed above, four have values that are single file
-names, and three have values that are lists of file names.  These
-seven have variants that get just the file's directory name or just
-the file name within the directory.  The variant variables' names are
-formed by appending @samp{D} or @samp{F}, respectively.  The functions
-@code{dir} and @code{notdir} can be used to obtain a similar effect
-(@pxref{File Name Functions, , Functions for File Names}).  Note,
-however, that the @samp{D} variants all omit the trailing slash which
-always appears in the output of the @code{dir} function.  Here is a
-table of the variants:
-
-@table @samp
-@vindex $(@@D)
-@vindex @@D @r{(automatic variable)}
-@item $(@@D)
-The directory part of the file name of the target, with the trailing
-slash removed.  If the value of @samp{$@@} is @file{dir/foo.o} then

-not contain a slash.
-
-@vindex $(@@F)
-@vindex @@F @r{(automatic variable)}
-@item $(@@F)
-The file-within-directory part of the file name of the target.  If the

-@w{``the variable @code{<}''} as we would write for ordinary variables
-such as @code{objects} and @code{CFLAGS}.  We think this convention

-@node Pattern Match, Match-Anything Rules, Automatic Variables, Pattern Rules
-@subsection How Patterns Match
-
-@cindex stem
-A target pattern is composed of a @samp{%} between a prefix and a suffix,
-either or both of which may be empty.  The pattern matches a file name only
-if the file name starts with the prefix and ends with the suffix, without
-overlap.  The text between the prefix and the suffix is called the
-@dfn{stem}.  Thus, when the pattern @samp{%.o} matches the file name
-@file{test.o}, the stem is @samp{test}.  The pattern rule prerequisites are
-turned into actual file names by substituting the stem for the character
-@samp{%}.  Thus, if in the same example one of the prerequisites is written
-as @samp{%.c}, it expands to @samp{test.c}.@refill
-
-When the target pattern does not contain a slash (and it usually does
-not), directory names in the file names are removed from the file name
-before it is compared with the target prefix and suffix.  After the
-comparison of the file name to the target pattern, the directory
-names, along with the slash that ends them, are added on to the
-prerequisite file names generated from the pattern rule's prerequisite
-patterns and the file name.  The directories are ignored only for the
-purpose of finding an implicit rule to use, not in the application of
-that rule.  Thus, @samp{e%t} matches the file name @file{src/eat},
-with @samp{src/a} as the stem.  When prerequisites are turned into file
-names, the directories from the stem are added at the front, while the
-rest of the stem is substituted for the @samp{%}.  The stem
-@samp{src/a} with a prerequisite pattern @samp{c%r} gives the file name
-@file{src/car}.@refill
-
-@cindex pattern rules, order of
-@cindex order of pattern rules
-A pattern rule can be used to build a given file only if there is a
-target pattern that matches the file name, @emph{and} all
-prerequisites in that rule either exist or can be built.  The rules
-you write take precedence over those that are built in. Note however,
-that a rule whose prerequisites actually exist or are mentioned always
-takes priority over a rule with prerequisites that must be made by
-chaining other implicit rules.
-
-@cindex stem, shortest
-It is possible that more than one pattern rule will meet these
-criteria.  In that case, @code{make} will choose the rule with the
-shortest stem (that is, the pattern that matches most specifically).
-If more than one pattern rule has the shortest stem, @code{make} will
-choose the first one found in the makefile.
-
-This algorithm results in more specific rules being preferred over
-more generic ones; for example:
-
-@example
-%.o: %.c
-        $(CC) -c $(CFLAGS) $(CPPFLAGS) $< -o $@@
-
-%.o : %.f
-        $(COMPILE.F) $(OUTPUT_OPTION) $<
-
-lib/%.o: lib/%.c
-        $(CC) -fPIC -c $(CFLAGS) $(CPPFLAGS) $< -o $@@
-@end example
-
-Given these rules and asked to build @file{bar.o} where both
-@file{bar.c} and @file{bar.f} exist, @code{make} will choose the first
-rule and compile @file{bar.c} into @file{bar.o}.  In the same
-situation where @file{bar.c} does not exist, then @code{make} will
-choose the second rule and compile @file{bar.f} into @file{bar.o}.
-
-If @code{make} is asked to build @file{lib/bar.o} and both
-@file{lib/bar.c} and @file{lib/bar.f} exist, then the third rule will
-be chosen since the stem for this rule (@samp{bar}) is shorter than
-the stem for the first rule (@samp{lib/bar}).  If @file{lib/bar.c}
-does not exist then the third rule is not eligible and the second rule
-will be used, even though the stem is longer.

-@subsection Match-Anything Pattern Rules
-
-@cindex match-anything rule
-@cindex terminal rule
-When a pattern rule's target is just @samp{%}, it matches any file name
-whatever.  We call these rules @dfn{match-anything} rules.  They are very
-useful, but it can take a lot of time for @code{make} to think about them,
-because it must consider every such rule for each file name listed either
-as a target or as a prerequisite.
-
-Suppose the makefile mentions @file{foo.c}.  For this target, @code{make}
-would have to consider making it by linking an object file @file{foo.c.o},
-or by C compilation-and-linking in one step from @file{foo.c.c}, or by
-Pascal compilation-and-linking from @file{foo.c.p}, and many other
-possibilities.
-
-We know these possibilities are ridiculous since @file{foo.c} is a C source
-file, not an executable.  If @code{make} did consider these possibilities,
-it would ultimately reject them, because files such as @file{foo.c.o} and
-@file{foo.c.p} would not exist.  But these possibilities are so
-numerous that @code{make} would run very slowly if it had to consider
-them.@refill
-
-To gain speed, we have put various constraints on the way @code{make}
-considers match-anything rules.  There are two different constraints that
-can be applied, and each time you define a match-anything rule you must
-choose one or the other for that rule.
-
-One choice is to mark the match-anything rule as @dfn{terminal} by defining
-it with a double colon.  When a rule is terminal, it does not apply unless
-its prerequisites actually exist.  Prerequisites that could be made with
-other implicit rules are not good enough.  In other words, no further
-chaining is allowed beyond a terminal rule.
-
-For example, the built-in implicit rules for extracting sources from RCS
-and SCCS files are terminal; as a result, if the file @file{foo.c,v} does
-not exist, @code{make} will not even consider trying to make it as an
-intermediate file from @file{foo.c,v.o} or from @file{RCS/SCCS/s.foo.c,v}.
-RCS and SCCS files are generally ultimate source files, which should not be
-remade from any other files; therefore, @code{make} can save time by not
-looking for ways to remake them.@refill
-
-If you do not mark the match-anything rule as terminal, then it is
-non-terminal.  A non-terminal match-anything rule cannot apply to a
-prerequisite of an implicit rule, or to a file name that indicates a
-specific type of data.  A file name indicates a specific type of data
-if some non-match-anything implicit rule target matches it.
-
-For example, the file name @file{foo.c} matches the target for the pattern
-rule @samp{%.c : %.y} (the rule to run Yacc).  Regardless of whether this
-rule is actually applicable (which happens only if there is a file
-@file{foo.y}), the fact that its target matches is enough to prevent
-consideration of any non-terminal match-anything rules for the file
-@file{foo.c}.  Thus, @code{make} will not even consider trying to make
-@file{foo.c} as an executable file from @file{foo.c.o}, @file{foo.c.c},
-@file{foo.c.p}, etc.@refill
-
-The motivation for this constraint is that non-terminal match-anything
-rules are used for making files containing specific types of data (such as
-executable files) and a file name with a recognized suffix indicates some
-other specific type of data (such as a C source file).
-
-Special built-in dummy pattern rules are provided solely to recognize
-certain file names so that non-terminal match-anything rules will not be
-considered.  These dummy rules have no prerequisites and no recipes, and
-they are ignored for all other purposes.  For example, the built-in
-implicit rule
-
-@example
-%.p :
-@end example
-
-@noindent
-exists to make sure that Pascal source files such as @file{foo.p} match a
-specific target pattern and thereby prevent time from being wasted looking
-for @file{foo.p.o} or @file{foo.p.c}.
-
-Dummy pattern rules such as the one for @samp{%.p} are made for every
-suffix listed as valid for use in suffix rules (@pxref{Suffix Rules, ,Old-Fashioned Suffix Rules}).

-@node Canceling Rules,  , Match-Anything Rules, Pattern Rules
-@subsection Canceling Implicit Rules
-
-You can override a built-in implicit rule (or one you have defined
-yourself) by defining a new pattern rule with the same target and
-prerequisites, but a different recipe.  When the new rule is defined, the
-built-in one is replaced.  The new rule's position in the sequence of
-implicit rules is determined by where you write the new rule.
-
-You can cancel a built-in implicit rule by defining a pattern rule with the

-would cancel the rule that runs the assembler:

-You can define a last-resort implicit rule by writing a terminal
-match-anything pattern rule with no prerequisites (@pxref{Match-Anything
-Rules}).  This is just like any other pattern rule; the only thing
-special about it is that it will match any target.  So such a rule's
-recipe is used for all targets and prerequisites that have no recipe
-of their own and for which no other implicit rule applies.
-
-For example, when testing a makefile, you might not care if the source
-files contain real data, only that they exist.  Then you might do this:
-
-@example
-%::
-        touch $@@
-@end example
-
-@noindent
-to cause all the source files needed (as prerequisites) to be created
-automatically.
-
-@findex .DEFAULT
-You can instead define a recipe to be used for targets for which there
-are no rules at all, even ones which don't specify recipes.  You do
-this by writing a rule for the target @code{.DEFAULT}.  Such a rule's
-recipe is used for all prerequisites which do not appear as targets in
-any explicit rule, and for which no implicit rule applies.  Naturally,
-there is no @code{.DEFAULT} rule unless you write one.
-
-If you use @code{.DEFAULT} with no recipe or prerequisites:
-
-@example
-.DEFAULT:
-@end example
-
-@noindent
-the recipe previously stored for @code{.DEFAULT} is cleared.  Then
-@code{make} acts as if you had never defined @code{.DEFAULT} at all.
-
-If you do not want a target to get the recipe from a match-anything
-pattern rule or @code{.DEFAULT}, but you also do not want any recipe
-to be run for the target, you can give it an empty recipe

-@node Suffix Rules, Implicit Rule Search, Last Resort, Implicit Rules
-@section Old-Fashioned Suffix Rules
-@cindex old-fashioned suffix rules
-@cindex suffix rule
-
-@dfn{Suffix rules} are the old-fashioned way of defining implicit rules for
-@code{make}.  Suffix rules are obsolete because pattern rules are more
-general and clearer.  They are supported in GNU @code{make} for
-compatibility with old makefiles.  They come in two kinds:
-@dfn{double-suffix} and @dfn{single-suffix}.@refill
-
-A double-suffix rule is defined by a pair of suffixes: the target
-suffix and the source suffix.  It matches any file whose name ends
-with the target suffix.  The corresponding implicit prerequisite is
-made by replacing the target suffix with the source suffix in the file
-name.  A two-suffix rule @samp{.c.o} (whose target and source suffixes
-are @samp{.o} and @samp{.c}) is equivalent to the pattern rule
-@samp{%.o : %.c}.
-
-A single-suffix rule is defined by a single suffix, which is the source
-suffix.  It matches any file name, and the corresponding implicit
-prerequisite name is made by appending the source suffix.  A single-suffix
-rule whose source suffix is @samp{.c} is equivalent to the pattern rule
-@samp{% : %.c}.
-
-Suffix rule definitions are recognized by comparing each rule's target
-against a defined list of known suffixes.  When @code{make} sees a rule
-whose target is a known suffix, this rule is considered a single-suffix
-rule.  When @code{make} sees a rule whose target is two known suffixes
-concatenated, this rule is taken as a double-suffix rule.
-
-For example, @samp{.c} and @samp{.o} are both on the default list of
-known suffixes.  Therefore, if you define a rule whose target is
-@samp{.c.o}, @code{make} takes it to be a double-suffix rule with source
-suffix @samp{.c} and target suffix @samp{.o}.  Here is the old-fashioned
-way to define the rule for compiling a C source file:@refill
-
-@example
-.c.o:
-        $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@@ $<
-@end example
-
-Suffix rules cannot have any prerequisites of their own.  If they have any,
-they are treated as normal files with funny names, not as suffix rules.
-Thus, the rule:
-
-@example
-.c.o: foo.h
-        $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@@ $<
-@end example
-
-@noindent
-tells how to make the file @file{.c.o} from the prerequisite file
-@file{foo.h}, and is not at all like the pattern rule:
-
-@example
-%.o: %.c foo.h
-        $(CC) -c $(CFLAGS) $(CPPFLAGS) -o $@@ $<
-@end example
-
-@noindent
-which tells how to make @samp{.o} files from @samp{.c} files, and makes all
-@samp{.o} files using this pattern rule also depend on @file{foo.h}.
-
-Suffix rules with no recipe are also meaningless.  They do not remove
-previous rules as do pattern rules with no recipe (@pxref{Canceling
-Rules, , Canceling Implicit Rules}).  They simply enter the suffix or
-pair of suffixes concatenated as a target in the data base.@refill
-
-@findex .SUFFIXES
-The known suffixes are simply the names of the prerequisites of the special
-target @code{.SUFFIXES}.  You can add your own suffixes by writing a rule
-for @code{.SUFFIXES} that adds more prerequisites, as in:
-
-@example
-.SUFFIXES: .hack .win
-@end example
-
-@noindent
-which adds @samp{.hack} and @samp{.win} to the end of the list of suffixes.
-
-If you wish to eliminate the default known suffixes instead of just adding
-to them, write a rule for @code{.SUFFIXES} with no prerequisites.  By
-special dispensation, this eliminates all existing prerequisites of
-@code{.SUFFIXES}.  You can then write another rule to add the suffixes you
-want.  For example,
-
-@example
-@group
-.SUFFIXES:            # @r{Delete the default suffixes}
-.SUFFIXES: .c .o .h   # @r{Define our suffix list}
-@end group
-@end example
-
-The @samp{-r} or @samp{--no-builtin-rules} flag causes the default
-list of suffixes to be empty.
-
-@vindex SUFFIXES
-The variable @code{SUFFIXES} is defined to the default list of suffixes
-before @code{make} reads any makefiles.  You can change the list of suffixes
-with a rule for the special target @code{.SUFFIXES}, but that does not alter
-this variable.

-@section Archive Members as Targets
-@cindex archive member targets
-
-An individual member of an archive file can be used as a target or
-prerequisite in @code{make}.  You specify the member named @var{member} in
-archive file @var{archive} as follows:
-
-@example
-@var{archive}(@var{member})
-@end example
-
-@noindent
-This construct is available only in targets and prerequisites, not in
-recipes!  Most programs that you might use in recipes do not support
-this syntax and cannot act directly on archive members.  Only
-@code{ar} and other programs specifically designed to operate on
-archives can do so.  Therefore, valid recipes to update an archive
-member target probably must use @code{ar}.  For example, this rule
-says to create a member @file{hack.o} in archive @file{foolib} by
-copying the file @file{hack.o}:
-
-@example
-foolib(hack.o) : hack.o
-        ar cr foolib hack.o
-@end example
-
-In fact, nearly all archive member targets are updated in just this way
-and there is an implicit rule to do it for you.  @strong{Please note:} The
-@samp{c} flag to @code{ar} is required if the archive file does not
-already exist.
-
-To specify several members in the same archive, you can write all the
-member names together between the parentheses.  For example:
-
-@example
-foolib(hack.o kludge.o)
-@end example
-
-@noindent
-is equivalent to:

-feature it considers implicit rules that match @file{(@var{m})}, as well as
-those that match the actual target @file{@var{a}(@var{m})}.
-
-This causes one special rule whose target is @file{(%)} to match.  This
-rule updates the target @file{@var{a}(@var{m})} by copying the file @var{m}
-into the archive.  For example, it will update the archive member target
-@file{foo.a(bar.o)} by copying the @emph{file} @file{bar.o} into the
-archive @file{foo.a} as a @emph{member} named @file{bar.o}.
-
-When this rule is chained with others, the result is very powerful.
-Thus, @samp{make "foo.a(bar.o)"} (the quotes are needed to protect the
-@samp{(} and @samp{)} from being interpreted specially by the shell) in
-the presence of a file @file{bar.c} is enough to cause the following
-recipe to be run, even without a makefile:
-
-@example
-cc -c bar.c -o bar.o
-ar r foo.a bar.o
-rm -f bar.o
-@end example
-
-@noindent
-Here @code{make} has envisioned the file @file{bar.o} as an intermediate
-file.  @xref{Chained Rules, ,Chains of Implicit Rules}.
-
-Implicit rules such as this one are written using the automatic variable
-@samp{$%}.  @xref{Automatic Variables}.
-
-An archive member name in an archive cannot contain a directory name, but
-it may be useful in a makefile to pretend that it does.  If you write an
-archive member target @file{foo.a(dir/file.o)}, @code{make} will perform
-automatic updating with this recipe:
-
-@example
-ar r foo.a dir/file.o
-@end example
-
-@noindent
-which has the effect of copying the file @file{dir/file.o} into a member
-named @file{file.o}.  In connection with such usage, the automatic variables
-@code{%D} and @code{%F} may be useful.

-@cindex directories, updating archive symbol
-
-An archive file that is used as a library usually contains a special member
-named @file{__.SYMDEF} that contains a directory of the external symbol
-names defined by all the other members.  After you update any other
-members, you need to update @file{__.SYMDEF} so that it will summarize the
-other members properly.  This is done by running the @code{ranlib} program:
-
-@example
-ranlib @var{archivefile}
-@end example
-
-Normally you would put this command in the rule for the archive file,
-and make all the members of the archive file prerequisites of that rule.
-For example,
-
-@example
-libfoo.a: libfoo.a(x.o) libfoo.a(y.o) @dots{}
-        ranlib libfoo.a
-@end example
-
-@noindent
-The effect of this is to update archive members @file{x.o}, @file{y.o},
-etc., and then update the symbol directory member @file{__.SYMDEF} by
-running @code{ranlib}.  The rules for updating the members are not shown
-here; most likely you can omit them and use the implicit rule which copies
-files into the archive, as described in the preceding section.
-
-This is not necessary when using the GNU @code{ar} program, which
-updates the @file{__.SYMDEF} member automatically.

-@cindex suffix rule, for archive

-@cindex library archive, suffix rule for
-@cindex @code{.a} (archives)
-
-You can write a special kind of suffix rule for dealing with archive
-files.  @xref{Suffix Rules}, for a full explanation of suffix rules.
-Archive suffix rules are obsolete in GNU @code{make}, because pattern
-rules for archives are a more general mechanism (@pxref{Archive
-Update}).  But they are retained for compatibility with other
-@code{make}s.
-
-To write a suffix rule for archives, you simply write a suffix rule
-using the target suffix @samp{.a} (the usual suffix for archive files).
-For example, here is the old-fashioned suffix rule to update a library
-archive from C source files:
-
-@example
-@group
-.c.a:
-        $(CC) $(CFLAGS) $(CPPFLAGS) -c $< -o $*.o
-        $(AR) r $@@ $*.o
-        $(RM) $*.o
-@end group
-@end example
-
-@noindent
-This works just as if you had written the pattern rule:
-
-@example
-@group
-(%.o): %.c
-        $(CC) $(CFLAGS) $(CPPFLAGS) -c $< -o $*.o
-        $(AR) r $@@ $*.o
-        $(RM) $*.o
-@end group
-@end example
-
-In fact, this is just what @code{make} does when it sees a suffix rule
-with @samp{.a} as the target suffix.  Any double-suffix rule
-@w{@samp{.@var{x}.a}} is converted to a pattern rule with the target
-pattern @samp{(%.o)} and a prerequisite pattern of @samp{%.@var{x}}.
-
-Since you might want to use @samp{.a} as the suffix for some other kind
-of file, @code{make} also converts archive suffix rules to pattern rules
-in the normal way (@pxref{Suffix Rules}).  Thus a double-suffix rule
-@w{@samp{.@var{x}.a}} produces two pattern rules: @samp{@w{(%.o):}
-@w{%.@var{x}}} and @samp{@w{%.a}: @w{%.@var{x}}}.@refill

-@chapter Extending GNU @code{make}
-@cindex make extensions
-
-GNU @code{make} provides many advanced capabilities, including many
-useful functions.  However, it does not contain a complete programming
-language and so it has limitations.  Sometimes these limitations can be
-overcome through use of the @code{shell} function to invoke a separate
-program, although this can be inefficient.
-
-In cases where the built-in capabilities of GNU @code{make} are
-insufficient to your requirements there are two options for extending
-@code{make}.  On systems where it's provided, you can utilize GNU
-Guile as an embedded scripting language (@pxref{Guile Integration,,GNU
-Guile Integration}).  On systems which support dynamically loadable
-objects, you can write your own extension in any language (which can
-be compiled into such an object) and load it to provide extended
-capabilities (@pxref{load Directive, ,The @code{load} Directive}).

-@cindex extensions, Guile
-
-GNU @code{make} may be built with support for GNU Guile as an embedded
-extension language.  Guile implements the Scheme language.  A review
-of GNU Guile and the Scheme language and its features is beyond the
-scope of this manual: see the documentation for GNU Guile and Scheme.
-
-You can determine if @code{make} contains support for Guile by
-examining the @code{.FEATURES} variable; it will contain the word
-@var{guile} if Guile support is available.
-
-The Guile integration provides one new @code{make} function: @code{guile}.
-The @code{guile} function takes one argument which is first expanded
-by @code{make} in the normal fashion, then passed to the GNU Guile
-evaluator.  The result of the evaluator is converted into a string and
-used as the expansion of the @code{guile} function in the makefile.
-
-In addition, GNU @code{make} exposes Guile procedures for use in Guile
-scripts.

-@subsection Conversion of Guile Types
-@cindex convert guile types
-@cindex guile, conversion of types
-@cindex types, conversion of
-
-There is only one ``data type'' in @code{make}: a string.  GNU Guile,
-on the other hand, provides a rich variety of different data types.
-An important aspect of the interface between @code{make} and GNU Guile
-is the conversion of Guile data types into @code{make} strings.
-
-This conversion is relevant in two places: when a makefile invokes the
-@code{guile} function to evaluate a Guile expression, the result of
-that evaluation must be converted into a make string so it can be
-further evaluated by @code{make}.  And secondly, when a Guile script
-invokes one of the procedures exported by @code{make} the argument
-provided to the procedure must be converted into a string.
-
-The conversion of Guile types into @code{make} strings is as below:
-
-@table @code
-@item #f
-False is converted into the empty string: in @code{make} conditionals
-the empty string is considered false.
-
-@item #t
-True is converted to the string @samp{#t}: in @code{make} conditionals
-any non-empty string is considered true.
-
-@item symbol
-@item number
-A symbol or number is converted into the string representation of that
-symbol or number.
-
-@item character
-A printable character is converted to the same character.
-
-@item string
-A string containing only printable characters is converted to the same
-string.
-
-@item list
-A list is converted recursively according to the above rules.  This
-implies that any structured list will be flattened (that is, a result
-of @samp{'(a b (c d) e)} will be converted to the @code{make} string
-@samp{a b c d e}).
-
-@item other
-Any other Guile type results in an error.  In future versions of
-@code{make}, other Guile types may be converted.
-
-@end table
-
-The translation of @samp{#f} (to the empty string) and @samp{#t} (to
-the non-empty string @samp{#t}) is designed to allow you to use Guile
-boolean results directly as @code{make} boolean conditions.  For
-example:
-
-@example
-$(if $(guile (access? "myfile" R_OK)),$(info myfile exists))
-@end example
-
-As a consequence of these conversion rules you must consider the
-result of your Guile script, as that result will be converted into a
-string and parsed by @code{make}.  If there is no natural result for
-the script (that is, the script exists solely for its side-effects),
-you should add @samp{#f} as the final expression in order to avoid
-syntax errors in your makefile.

-@subsection Interfaces from Guile to @code{make}
-@cindex make interface to guile
-@cindex make procedures in guile
-
-In addition to the @code{guile} function available in makefiles,
-@code{make} exposes some procedures for use in your Guile scripts.  At
-startup @code{make} creates a new Guile module, @code{gnu make}, and
-exports these procedures as public interfaces from that module:
-
-@table @code
-@item gmk-expand
-@findex gmk-expand
-This procedure takes a single argument which is converted into a
-string.  The string is expanded by @code{make} using normal
-@code{make} expansion rules.  The result of the expansion is converted
-into a Guile string and provided as the result of the procedure.
-
-@item gmk-eval
-@findex gmk-eval
-This procedure takes a single argument which is converted into a
-string.  The string is evaluated by @code{make} as if it were a
-makefile.  This is the same capability available via the @code{eval}
-function (@pxref{Eval Function}).  The result of the @code{gmk-eval}
-procedure is always the empty string.
-
-Note that @code{gmk-eval} is not quite the same as using
-@code{gmk-expand} with the @code{eval} function: in the latter case
-the evaluated string will be expanded @emph{twice}; first by
-@code{gmk-expand}, then again by the @code{eval} function.

-@end table

-@node Guile Example,  , Guile Interface, Guile Integration
-@subsection Example Using Guile in @code{make}
-@cindex Guile example
-@cindex example using Guile
-
-Here is a very simple example using GNU Guile to manage writing to a
-file.  These Guile procedures simply open a file, allow writing to the
-file (one string per line), and close the file.  Note that because we
-cannot store complex values such as Guile ports in @code{make}
-variables, we'll keep the port as a global variable in the Guile
-interpreter.
-
-You can create Guile functions easily using @code{define}/@code{endef}
-to create a Guile script, then use the @code{guile} function to
-internalize it:
-
-@example
-@group
-define GUILEIO
-;; A simple Guile IO library for GNU make
-
-(define MKPORT #f)
-
-(define (mkopen name mode)
-  (set! MKPORT (open-file name mode))
-  #f)
-
-(define (mkwrite s)
-  (display s MKPORT)
-  (newline MKPORT)
-  #f)
-
-(define (mkclose)
-  (close-port MKPORT)
-  #f)
-
-#f
-endef
-
-# Internalize the Guile IO functions
-$(guile $(GUILEIO))
-@end group
-@end example
-
-If you have a significant amount of Guile support code, you might
-consider keeping it in a different file (e.g., @file{guileio.scm}) and
-then loading it in your makefile using the @code{guile} function:
-
-@example
-$(guile (load "guileio.scm"))
-@end example
-
-An advantage to this method is that when editing @file{guileio.scm},
-your editor will understand that this file contains Scheme syntax
-rather than makefile syntax.
-
-Now you can use these Guile functions to create files.  Suppose you
-need to operate on a very large list, which cannot fit on the command
-line, but the utility you're using accepts the list as input as well:
-
-@example
-@group
-prog: $(PREREQS)
-        @@$(guile (mkopen "tmp.out" "w")) \
-         $(foreach X,$^,$(guile (mkwrite "$(X)"))) \
-         $(guile (mkclose))
-        $(LINK) < tmp.out
-@end group
-@end example
-
-A more comprehensive suite of file manipulation procedures is possible
-of course.  You could, for example, maintain multiple output files at
-the same time by choosing a symbol for each one and using it as the
-key to a hash table, where the value is a port, then returning the
-symbol to be stored in a @code{make} variable.

-directive into your makefile.  The syntax of the @code{load} directive
-is as follows:
-
-@findex load
-@example
-load @var{object-file} @dots{}
-@end example
-
-or:
-
-@example
-load @var{object-file}(@var{symbol-name}) @dots{}
-@end example
-
-The file @var{object-file} is dynamically loaded by GNU @code{make}.
-If @var{object-file} does not include a directory path then it is
-first looked for in the current directory.  If it is not found there,
-or a directory path is included, then system-specific paths will be
-searched.  If the load fails for any reason, @code{make} will print a
-message and exit.
-
-If the load succeeds @code{make} will invoke an initializing function.
-
-If @var{symbol-name} is provided, it will be used as the name of the
-initializing function.
-
-If no @var{symbol-name} is provided, the initializing function name is
-created by taking the base file name of @var{object-file}, up to the
-first character which is not a valid symbol name character
-(alphanumerics and underscores are valid symbol name characters).  To
-this prefix will be appended the suffix @code{_gmk_setup}.
-
-More than one object file may be loaded with a single @code{load}
-directive, and both forms of @code{load} arguments may be used in the
-same directive.
-
-The initializing function will be provided the file name and line
-number of the invocation of the @code{load} operation.  It should
-return a value of type @code{int}, which must be @code{0} on failure
-and non-@code{0} on success.  If the return value is @code{-1}, then
-GNU make will @emph{not} attempt to rebuild the object file
-(@pxref{Remaking Loaded Objects, ,How Loaded Objects Are Remade}).
-
-For example:
-
-@example
-load ../mk_funcs.so
-@end example
-
-will load the dynamic object @file{../mk_funcs.so}.  After the object
-is loaded, @code{make} will invoke the function (assumed to be defined
-by the shared object) @code{mk_funcs_gmk_setup}.
-
-On the other hand:
-
-@example
-load ../mk_funcs.so(init_mk_func)
-@end example
-
-will load the dynamic object @file{../mk_funcs.so}.  After the object
-is loaded, @code{make} will invoke the function @code{init_mk_func}.
-
-Regardless of how many times an object file appears in a @code{load}
-directive, it will only be loaded (and its setup function will only
-be invoked) once.
-
-@vindex .LOADED
-After an object has been successfully loaded, its file name is
-appended to the @code{.LOADED} variable.
-
-@findex -load
-If you would prefer that failure to load a dynamic object not be
-reported as an error, you can use the @code{-load} directive instead
-of @code{load}.  GNU @code{make} will not fail and no message will be
-generated if an object fails to load.  The failed object is not added
-to the @code{.LOADED} variable, which can then be consulted to
-determine if the load was successful.

-functions may be added, removed, or change calling signatures or
-implementations in future versions of GNU @code{make}.
-@end quotation
-@end cartouche
-
-To be useful, loaded objects must be able to interact with GNU
-@code{make}.  This interaction includes both interfaces the loaded

-to the loaded object to manipulate @code{make}'s operation.
-
-The interface between loaded objects and @code{make} is defined by the
-@file{gnumake.h} C header file.  All loaded objects written in C
-should include this header file.  Any loaded object not written in C
-will need to implement the interface defined in this header file.
-
-Typically, a loaded object will register one or more new GNU
-@code{make} functions using the @code{gmk_add_function} routine from
-within its setup function.  The implementations of these @code{make}
-functions may make use of the @code{gmk_expand} and @code{gmk_eval}

-under a GPL-compatible license.  If this symbol does not exist,
-@code{make} emits a fatal error and exits when it tries to load your
-extension.
-
-The declared type of the symbol should be @code{int}. It does not need
-to be in any allocated section, though.  The code merely asserts that

-which may then be invoked from within the makefile in the same way as
-any other function.
-
-Use @code{gmk_add_function} to create a new @code{make} function.  Its
-arguments are as follows:
-
-@table @code
-@item name
-The function name.  This is what the makefile should use to invoke the
-function.  The name must be between 1 and 255 characters long and it
-may only contain alphanumeric, period (@samp{.}), dash (@samp{-}), and
-underscore (@samp{_}) characters.  It may not begin with a period.
-
-@item func_ptr
-A pointer to a function that @code{make} will invoke when it expands
-the function in a makefile.  This function must be defined by the
-loaded object.
-
-@item min_args
-The minimum number of arguments the function will accept.  Must be
-between 0 and 255.  GNU @code{make} will check this and fail before
-invoking @code{func_ptr} if the function was invoked with too few
-arguments.
-
-@item max_args
-The maximum number of arguments the function will accept.  Must be
-between 0 and 255.  GNU @code{make} will check this and fail before
-invoking @code{func_ptr} if the function was invoked with too few
-arguments.  If the value is 0, then any number of arguments is
-accepted.  If the value is greater than 0, then it must be greater
-than or equal to @code{min_args}.
-
-@item flags
-Flags that specify how this function will operate; the desired flags
-should be OR'd together.  If the @code{GMK_FUNC_NOEXPAND} flag is
-given then the function arguments will not be expanded before the

-
-@subsubheading Registered Function Interface
-@findex gmk_func_ptr

-@code{name} (the name of the function), @code{argc} (the number of
-arguments to the function), and @code{argv} (an array of pointers to
-arguments to the function).  The last pointer (that is,
-@code{argv[argc]}) will be null (@code{0}).
-
-The return value of the function is the result of expanding the
-function.  If the function expands to nothing the return value may be
-null.  Otherwise, it must be a pointer to a string created with
-@code{gmk_alloc}.  Once the function returns, @code{make} owns this
-string and will free it when appropriate; it cannot be accessed by the
-loaded object.
-
-@subsubheading GNU @code{make} Facilities
-
-There are some facilities exported by GNU @code{make} for use by
-loaded objects.  Typically these would be run from within the

-works with.
-
-@table @code
-@item gmk_expand
-@findex gmk_expand
-This function takes a string and expands it using @code{make}

-@item gmk_eval
-@findex gmk_eval
-This function takes a buffer and evaluates it as a segment of makefile
-syntax.  This function can be used to define new variables, new rules,
-etc.  It is equivalent to using the @code{eval} @code{make} function.
-@end table
-
-Note that there is a difference between @code{gmk_eval} and calling
-@code{gmk_expand} with a string using the @code{eval} function: in
-the latter case the string will be expanded @emph{twice}; once by
-@code{gmk_expand} and then again by the @code{eval} function.  Using
-@code{gmk_eval} the buffer is only expanded once, at most (as it's
-read by the @code{make} parser).
-
-@subsubheading Memory Management
-
-Some systems allow for different memory management schemes.  Thus you
-should never pass memory that you've allocated directly to any
-@code{make} function, nor should you attempt to directly free any
-memory returned to you by any @code{make} function.  Instead, use the
-@code{gmk_alloc} and @code{gmk_free} functions.
-
-In particular, the string returned to @code{make} by a function
-registered using @code{gmk_add_function} @emph{must} be allocated
-using @code{gmk_alloc}, and the string returned from the @code{make}
-@code{gmk_expand} function @emph{must} be freed (when no longer
-needed) using @code{gmk_free}.
-
-@table @code
-@item gmk_alloc
-@findex gmk_alloc
-Return a pointer to a newly-allocated buffer.  This function will
-always return a valid pointer; if not enough memory is available
-@code{make} will exit.
-
-@item gmk_free
-@findex gmk_free
-Free a buffer returned to you by @code{make}.  Once the
-@code{gmk_free} function returns the string will no longer be valid.

-@cindex make integration
-
-GNU @code{make} is often one component in a larger system of tools,
-including integrated development environments, compiler toolchains,
-and others.  The role of @code{make} is to start commands and
-determine whether they succeeded or not: no special integration is
-needed to accomplish that.  However, sometimes it is convenient to
-bind @code{make} more tightly with other parts of the system, both
-higher-level (tools that invoke @code{make}) and lower-level (tools
-that @code{make} invokes).

-@cindex job slots, sharing
-@cindex tools, sharing job slots
-
-GNU @code{make} has the ability to run multiple recipes in parallel
-(@pxref{Parallel, ,Parallel Execution}) and to cap the total number of
-parallel jobs even across recursive invocations of @code{make}
-(@pxref{Options/Recursion, ,Communicating Options to a
-Sub-@code{make}}).  Tools that @code{make} invokes which are also able
-to run multiple operations in parallel, either using multiple threads
-or multiple processes, can be enhanced to participate in GNU
-@code{make}'s job management facility to ensure that the total number
-of active threads/processes running on the system does not exceed the
-maximum number of slots provided to GNU @code{make}. @refill
-
-@cindex jobserver
-GNU @code{make} uses a method called the ``jobserver'' to control the
-number of active jobs across recursive invocations.  The actual
-implementation of the jobserver varies across different operating
-systems, but some fundamental aspects are always true.
-
-First, only command lines that @code{make} understands to be recursive
-invocations of @code{make} (@pxref{MAKE Variable, ,How the @code{MAKE}
-Variable Works}) will have access to the jobserver.  When writing
-makefiles you must be sure to mark the command as recursive (most
-commonly by prefixing the command line with the @code{+} indicator
-(@pxref{Recursion, ,Recursive Use of @code{make}}).
-
-Second, @code{make} will provide information necessary for accessing
-the jobserver through the environment to its children, in the
-@code{MAKEFLAGS} environment variable.  Tools which want to
-participate in the jobserver protocol will need to parse this
-environment variable, as described in subsequent sections.
-
-Third, every command @code{make} starts has one implicit job slot
-reserved for it before it starts.  Any tool which wants to participate
-in the jobserver protocol should assume it can always run one job
-without having to contact the jobserver at all.
-
-Finally, it's critical that tools that participate in the jobserver
-protocol return the exact number of slots they obtained from the
-jobserver back to the jobserver before they exit, even under error
-conditions.  Remember that the implicit job slot should @strong{not}
-be returned to the jobserver!  Returning too few slots means that
-those slots will be lost for the rest of the build process; returning
-too many slots means that extra slots will be available.  The
-top-level @code{make} command will print an error message at the end
-of the build if it detects an incorrect number of slots available in
-the jobserver.
-
-As an example, suppose you are implementing a linker which provides
-for multithreaded operation.  You would like to enhance the linker so
-that if it is invoked by GNU @code{make} it can participate in the
-jobserver protocol to control how many threads are used during link.
-First you will need to modify the linker to determine if the
-@code{MAKEFLAGS} environment variable is set.  Next you will need to
-parse the value of that variable to determine if the jobserver is
-available, and how to access it.  If it is available then you can
-access it to obtain job slots controlling how much parallelism your
-tool can use.  Once done your tool must return those job slots back to
-the jobserver.

-@node POSIX Jobserver, Windows Jobserver, Job Slots, Job Slots
-@subsection POSIX Jobserver Interaction
-@cindex jobserver on POSIX
-
-On POSIX systems the jobserver is implemented as a simple UNIX pipe.
-The pipe will be pre-loaded with one single-character token for each
-available job.  To obtain an extra slot you must read a single
-character from the jobserver pipe; to release a slot you must write a
-single character back into the jobserver pipe.  Note that the read
-side of the jobserver pipe is set to ``blocking'' mode.
-
-To access the pipe you must parse the @code{MAKEFLAGS} variable and
-look for the argument string @code{--jobserver-auth=R,W} where
-@samp{R} and @samp{W} are non-negative integers representing file
-descriptors: @samp{R} is the read file descriptor and @samp{W} is the
-write file descriptor.
-
-It's important that when you release the job slot, you write back the
-same character you read from the pipe for that slot.  Don't assume
-that all tokens are the same character; different characters may have
-different meanings to GNU @code{make}.  The order is not important,
-since @code{make} has no idea in what order jobs will complete anyway.
-
-There are various error conditions you must consider to ensure your
-implementation is robust:
-
-@itemize @bullet
-@item
-Usually you will have a command-line argument controlling the parallel
-operation of your tool.  Consider whether your tool should detect
-situations where both the jobserver and the command-line argument are
-specified, and how it should react.
-
-@item
-If your tool determines that the @code{--jobserver-auth} option is
-available in @code{MAKEFLAGS} but that the file descriptors specified
-are closed, this means that the calling @code{make} process did not
-think that your tool was a recursive @code{make} invocation (e.g., the
-command line was not prefixed with a @code{+} character).  You should
-notify your users of this situation.
-
-@item
-Your tool should also examine the first word of the @code{MAKEFLAGS}
-variable and look for the character @code{n}.  If this character is
-present then @code{make} was invoked with the @samp{-n} option and
-your tool should stop without performing any operations.
-
-@item
-Your tool should be sure to write back the tokens it read, even under
-error conditions.  This includes not only errors in your tool but also
-outside influences such as interrupts (@code{SIGINT}), etc.  You may
-want to install signal handlers to manage this write-back.
-@end itemize
-
-@node Windows Jobserver,  , POSIX Jobserver, Job Slots
-@subsection Windows Jobserver Interaction
-@cindex jobserver on Windows
-
-On Windows systems the jobserver is implemented as a named semaphore.
-The semaphore will be set with an initial count equal to the number of
-available slots; to obtain a slot you must wait on the semaphore (with
-or without a timeout).  To release a slot, release the semaphore.
-
-To access the semaphore you must parse the @code{MAKEFLAGS} variable and
-look for the argument string @code{--jobserver-auth=NAME} where
-@samp{NAME} is the name of the named semaphore.  Use this name with
-@code{OpenSemaphore} to create a handle to the semaphore.
-
-There are various error conditions you must consider to ensure your

-@cindex parallel output to terminal
-@cindex terminal, output to
-
-Normally GNU @code{make} will invoke all commands with access to the
-same standard and error outputs that @code{make} itself was started
-with.  A number of tools will detect whether the output is a terminal
-or not-a-terminal, and use this information to change the output
-style.  For example if the output goes to a terminal the tool may add
-control characters that set color, or even change the location of the
-cursor.  If the output is not going to a terminal then these special
-control characters are not emitted so that they don't corrupt log
-files, etc.
-
-The @code{--output-sync} (@pxref{Parallel Output, ,Output During
-Parallel Output}) option will defeat the terminal detection.  When
-output synchronization is enabled GNU @code{make} arranges for all
-command output to be written to a file, so that its output can be
-written as a block without interference from other commands.  This
-means that all tools invoked by @code{make} will believe that their
-output is not going to be displayed on a terminal, even when it will
-be (because @code{make} will display it there after the command is
-completed).
-
-In order to facilitate tools which would like to determine whether or
-not their output will be displayed on a terminal, GNU @code{make} will
-set the @code{MAKE_TERMOUT} and @code{MAKE_TERMERR} environment
-variables before invoking any commands.  Tools which would like to
-determine whether standard or error output (respectively) will be
-displayed on a terminal can check these environment variables to
-determine if they exist and contain a non-empty value.  If so the tool
-can assume that the output will (eventually) be displayed on a
-terminal.  If the variables are not set or have an empty value, then
-the tool should fall back to its normal methods of detecting whether
-output is going to a terminal or not.
-
-The content of the variables can be parsed to determine the type of
-terminal which will be used to display the output.
-
-Similarly, environments which invoke @code{make} and would like to
-capture the output and eventually display it on a terminal (or some
-display which can interpret terminal control characters) can set these
-variables before invoking @code{make}.  GNU @code{make} will not
-modify these environment variables if they already exist when it
-starts.

-In some Unix @code{make}s, the automatic variable @code{$*} appearing in
-the prerequisites of a rule has the amazingly strange ``feature'' of
-expanding to the full name of the @emph{target of that rule}.  We cannot
-imagine what went on in the minds of Unix @code{make} developers to do
-this; it is utterly inconsistent with the normal definition of @code{$*}.
-@vindex * @r{(automatic variable), unsupported bizarre usage}
-
-@item
-In some Unix @code{make}s, implicit rule search (@pxref{Implicit
-Rules, ,Using Implicit Rules}) is apparently done for @emph{all}
-targets, not just those without recipes.  This means you can
-do:@refill
-
-@example
-@group
-foo.o:
-        cc -c foo.c
-@end group
-@end example
-
-@noindent
-and Unix @code{make} will intuit that @file{foo.o} depends on
-@file{foo.c}.@refill
-
-We feel that such usage is broken.  The prerequisite properties of
-@code{make} are well-defined (for GNU @code{make}, at least),
-and doing such a thing simply does not fit the model.@refill
-
-@item
-GNU @code{make} does not include any built-in implicit rules for
-compiling or preprocessing EFL programs.  If we hear of anyone who is
-using EFL, we will gladly add them.
-
-@item
-It appears that in SVR4 @code{make}, a suffix rule can be specified
-with no recipe, and it is treated as if it had an empty recipe
-(@pxref{Empty Recipes}).  For example:
-
-@example
-.c.a:
-@end example
-
-@noindent
-will override the built-in @file{.c.a} suffix rule.
-
-We feel that it is cleaner for a rule without a recipe to always simply
-add to the prerequisite list for the target.  The above example can be
-easily rewritten to get the desired behavior in GNU @code{make}:
-
-@example
-.c.a: ;
-@end example
-
-@item
-Some versions of @code{make} invoke the shell with the @samp{-e} flag,
-except under @samp{-k} (@pxref{Testing, ,Testing the Compilation of a
-Program}).  The @samp{-e} flag tells the shell to exit as soon as any
-program it runs returns a nonzero status.  We feel it is cleaner to
-write each line of the recipe to stand on its own and not require this
-special treatment.

-@appendix Errors Generated by Make
-
-Here is a list of the more common errors you might see generated by
-@code{make}, and some information about what they mean and how to fix
-them.
-
-Sometimes @code{make} errors are not fatal, especially in the presence
-of a @code{-} prefix on a recipe line, or the @code{-k} command line
-option.  Errors that are fatal are prefixed with the string
-@code{***}.
-
-Error messages are all either prefixed with the name of the program
-(usually @samp{make}), or, if the error is found in a makefile, the name
-of the file and line number containing the problem.
-
-In the table below, these common prefixes are left off.
-
-@table @samp
-
-@item [@var{foo}] Error @var{NN}
-@itemx [@var{foo}] @var{signal description}
-These errors are not really @code{make} errors at all.  They mean that a
-program that @code{make} invoked as part of a recipe returned a
-non-0 error code (@samp{Error @var{NN}}), which @code{make} interprets
-as failure, or it exited in some other abnormal fashion (with a
-signal of some type).  @xref{Errors, ,Errors in Recipes}.
-
-If no @code{***} is attached to the message, then the sub-process failed
-but the rule in the makefile was prefixed with the @code{-} special
-character, so @code{make} ignored the error.
-
-@item missing separator.  Stop.
-@itemx missing separator (did you mean TAB instead of 8 spaces?).  Stop.
-This means that @code{make} could not understand much of anything
-about the makefile line it just read.  GNU @code{make} looks for
-various separators (@code{:}, @code{=}, recipe prefix characters,
-etc.) to indicate what kind of line it's parsing.  This message means
-it couldn't find a valid one.
-
-One of the most common reasons for this message is that you (or
-perhaps your oh-so-helpful editor, as is the case with many MS-Windows
-editors) have attempted to indent your recipe lines with spaces
-instead of a tab character.  In this case, @code{make} will use the
-second form of the error above.  Remember that every line in the
-recipe must begin with a tab character (unless you set
-@code{.RECIPEPREFIX}; @pxref{Special Variables}).  Eight spaces do not
-count.  @xref{Rule Syntax}.
-
-@item recipe commences before first target.  Stop.
-@itemx missing rule before recipe.  Stop.
-This means the first thing in the makefile seems to be part of a
-recipe: it begins with a recipe prefix character and doesn't appear to
-be a legal @code{make} directive (such as a variable assignment).
-Recipes must always be associated with a target.
-
-The second form is generated if the line has a semicolon as the first
-non-whitespace character; @code{make} interprets this to mean you left
-out the "target: prerequisite" section of a rule.  @xref{Rule Syntax}.
-
-@item No rule to make target `@var{xxx}'.
-@itemx No rule to make target `@var{xxx}', needed by `@var{yyy}'.
-This means that @code{make} decided it needed to build a target, but
-then couldn't find any instructions in the makefile on how to do that,
-either explicit or implicit (including in the default rules database).
-
-If you want that file to be built, you will need to add a rule to your
-makefile describing how that target can be built.  Other possible
-sources of this problem are typos in the makefile (if that file name is
-wrong) or a corrupted source tree (if that file is not supposed to be
-built, but rather only a prerequisite).
-
-@item No targets specified and no makefile found.  Stop.
-@itemx No targets.  Stop.
-The former means that you didn't provide any targets to be built on the
-command line, and @code{make} couldn't find any makefiles to read in.
-The latter means that some makefile was found, but it didn't contain any
-default goal and none was given on the command line.  GNU @code{make}
-has nothing to do in these situations.
-@xref{Makefile Arguments, ,Arguments to Specify the Makefile}.@refill
-
-@item Makefile `@var{xxx}' was not found.
-@itemx Included makefile `@var{xxx}' was not found.
-A makefile specified on the command line (first form) or included
-(second form) was not found.
-
-@item warning: overriding recipe for target `@var{xxx}'
-@itemx warning: ignoring old recipe for target `@var{xxx}'
-GNU @code{make} allows only one recipe to be specified per target
-(except for double-colon rules).  If you give a recipe for a target
-which already has been defined to have one, this warning is issued and
-the second recipe will overwrite the first.  @xref{Multiple Rules,
-,Multiple Rules for One Target}.
-
-@item Circular @var{xxx} <- @var{yyy} dependency dropped.
-This means that @code{make} detected a loop in the dependency graph:
-after tracing the prerequisite @var{yyy} of target @var{xxx}, and its
-prerequisites, etc., one of them depended on @var{xxx} again.
-
-@item Recursive variable `@var{xxx}' references itself (eventually).  Stop.
-This means you've defined a normal (recursive) @code{make} variable
-@var{xxx} that, when it's expanded, will refer to itself (@var{xxx}).
-This is not allowed; either use simply-expanded variables (@samp{:=}
-or @samp{::=}) or use the append operator (@samp{+=}).  @xref{Using
-Variables, ,How to Use Variables}.
-
-@item Unterminated variable reference.  Stop.
-This means you forgot to provide the proper closing parenthesis
-or brace in your variable or function reference.
-
-@item insufficient arguments to function `@var{xxx}'.  Stop.
-This means you haven't provided the requisite number of arguments for
-this function.  See the documentation of the function for a description
-of its arguments.  @xref{Functions, ,Functions for Transforming Text}.
-
-@item missing target pattern.  Stop.
-@itemx multiple target patterns.  Stop.
-@itemx target pattern contains no `%'.  Stop.
-@itemx mixed implicit and static pattern rules.  Stop.
-These errors are generated for malformed static pattern rules
-(@pxref{Static Usage, ,Syntax of Static Pattern Rules}).  The first
-means the target-pattern part of the rule is empty; the second means
-there are multiple pattern characters (@code{%}) in the target-pattern
-part; the third means there are no pattern characters in the
-target-pattern part; and the fourth means that all three parts of the
-static pattern rule contain pattern characters (@code{%})--the first
-part should not contain pattern characters.
-
-If you see these errors and you aren't trying to create a static
-pattern rule, check the value of any variables in your target and
-prerequisite lists to be sure they do not contain colons.
-
-@item warning: -jN forced in submake: disabling jobserver mode.
-This warning and the next are generated if @code{make} detects error
-conditions related to parallel processing on systems where
-sub-@code{make}s can communicate (@pxref{Options/Recursion,
-,Communicating Options to a Sub-@code{make}}).  This warning is
-generated if a recursive invocation of a @code{make} process is forced
-to have @samp{-j@var{N}} in its argument list (where @var{N} is greater
-than one).  This could happen, for example, if you set the @code{MAKE}
-environment variable to @samp{make -j2}.  In this case, the
-sub-@code{make} doesn't communicate with other @code{make} processes and
-will simply pretend it has two jobs of its own.
-
-@item warning: jobserver unavailable: using -j1.  Add `+' to parent make rule.
-In order for @code{make} processes to communicate, the parent will pass
-information to the child.  Since this could result in problems if the
-child process isn't actually a @code{make}, the parent will only do this
-if it thinks the child is a @code{make}.  The parent uses the normal
-algorithms to determine this (@pxref{MAKE Variable, ,How the @code{MAKE}
-Variable Works}).  If the makefile is constructed such that the parent
-doesn't know the child is a @code{make} process, then the child will
-receive only part of the information necessary.  In this case, the child
-will generate this warning message and proceed with its build in a
-sequential manner.
-
-@item warning: ignoring prerequisites on suffix rule definition
-According to POSIX, a suffix rule cannot contain prerequisites.  If a rule
-that could be a suffix rule has prerequisites it is interpreted as a simple
-explicit rule, with an odd target name.  This requirement is obeyed when
-POSIX-conforming mode is enabled (the @code{.POSIX} target is defined).  In
-versions of GNU @code{make} prior to 4.3, no warning was emitted and a
-suffix rule was created, however all prerequisites were ignored and were not
-part of the suffix rule.  Starting with GNU @code{make} 4.3 the behavior is
-the same, and in addition this warning is generated.  In a future version
-the POSIX-conforming behavior will be the only behavior: no rule with a
-prerequisite can be suffix rule and this warning will be removed.

-@appendix Complex Makefile Example
-
-Here is the makefile for the GNU @code{tar} program.  This is a
-moderately complex makefile.  The first line uses a @code{#!} setting
-to allow the makefile to be executed directly.
-
-Because it is the first target, the default goal is @samp{all}.  An
-interesting feature of this makefile is that @file{testpad.h} is a
-source file automatically created by the @code{testpad} program,
-itself compiled from @file{testpad.c}.
-
-If you type @samp{make} or @samp{make all}, then @code{make} creates
-the @file{tar} executable, the @file{rmt} daemon that provides
-remote tape access, and the @file{tar.info} Info file.
-
-If you type @samp{make install}, then @code{make} not only creates
-@file{tar}, @file{rmt}, and @file{tar.info}, but also installs
-them.
-
-If you type @samp{make clean}, then @code{make} removes the @samp{.o}
-files, and the @file{tar}, @file{rmt}, @file{testpad},
-@file{testpad.h}, and @file{core} files.
-
-If you type @samp{make distclean}, then @code{make} not only removes
-the same files as does @samp{make clean} but also the
-@file{TAGS}, @file{Makefile}, and @file{config.status} files.
-(Although it is not evident, this makefile (and
-@file{config.status}) is generated by the user with the
-@code{configure} program, which is provided in the @code{tar}
-distribution, but is not shown here.)
-
-If you type @samp{make realclean}, then @code{make} removes the same
-files as does @samp{make distclean} and also removes the Info files
-generated from @file{tar.texinfo}.
-
-In addition, there are targets @code{shar} and @code{dist} that create
-distribution kits.

-#                       of open, and want to emulate it
-#                       with system calls you do have.

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+   for FUNCTION which will then trigger a compiler warning containing
+   the text of "literal string" anywhere that function is called, if
+   supported by the compiler.  If the compiler does not support this
+   feature, the macro expands to an unused extern declaration.
+
+   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
+   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
+   this feature, it expands to empty.
+
+   These macros are useful for marking a function as a potential
+   portability trap, with the intent that "literal string" include
+   instructions on the replacement function that should be used
+   instead.
+   _GL_WARN_ON_USE is for functions with 'extern' linkage.
+   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
+   linkage.
+
+   However, one of the reasons that a function is a portability trap is
+   if it has the wrong signature.  Declaring FUNCTION with a different
+   signature in C is a compilation error, so this macro must use the
+   same type as any existing declaration so that programs that avoid
+   the problematic FUNCTION do not fail to compile merely because they
+   included a header that poisoned the function.  But this implies that
+   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
+   have a declaration.  Use of this macro implies that there must not
+   be any other macro hiding the declaration of FUNCTION; but
+   undefining FUNCTION first is part of the poisoning process anyway
+   (although for symbols that are provided only via a macro, the result
+   is a compilation error rather than a warning containing
+   "literal string").  Also note that in C++, it is only safe to use if
+   FUNCTION has no overloads.
+
+   For an example, it is possible to poison 'getline' by:
+        [getline]) in configure.ac, which potentially defines
+     HAVE_RAW_DECL_GETLINE
+   - adding this code to a header that wraps the system <stdio.h>:
+     #undef getline
+     #if HAVE_RAW_DECL_GETLINE
+     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+       "not universally present; use the gnulib module getline");
+     #endif
+
+   It is not possible to directly poison global variables.  But it is
+   possible to write a wrapper accessor function, and poison that
+   (less common usage, like &environ, will cause a compilation error
+   rather than issue the nice warning, but the end result of informing
+   the developer about their portability problem is still achieved):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     rpl_environ (void) { return &environ; }
+     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
+     # undef environ
+     # define environ (*rpl_environ ())
+     #endif
+   or better (avoiding contradictory use of 'static' and 'extern'):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
+     rpl_environ (void) { return &environ; }

+                                is unique to HPUX9.  The best way to get the

+                                macro that comes with autoconf 2.13 or newer.
+                                If that isn't an option, then just put
+                                AC_CHECK_FUNCS(pstat_getdynamic) in your
+                                configure.ac file.
+   HAVE_LIBPERFSTAT Define this if your system has the
+                                perfstat_cpu_total function in libperfstat (AIX).
+   FIXUP_KERNEL_SYMBOL_ADDR()   Adjust address in returned struct nlist.
+   KERNEL_FILE                  Name of the kernel file to nlist.
+   LDAV_CVT()                   Scale the load average from the kernel.
+                                Returns a double.
+   LDAV_SYMBOL                  Name of kernel symbol giving load average.
+   LOAD_AVE_TYPE                Type of the load average array in the kernel.

+/* Determine if the load average on the system is too high to start a new job.
+
+   On systems which provide /proc/loadavg (e.g., Linux), we use an idea
+   provided by Sven C. Dack <sven.c.dack@sky.com>: retrieve the current number
+   of processes the kernel is running and, if it's greater than the requested
+   load we don't allow another job to start.  We allow a job to start with
+   equal processes since one of those will be for make itself, which will then
+   pause waiting for jobs to clear.
+
+   Otherwise, we obtain the system load average and compare that.
+
+   The system load average is only recomputed once every N (N>=1) seconds.
+   However, a very parallel make can easily start tens or even hundreds of
+   jobs in a second, which brings the system to its knees for a while until
+   that first batch of jobs clears out.
+
+   To avoid this we use a weighted algorithm to try to account for jobs which
+   have been started since the last second, and guess what the load average
+   would be now if it were computed.
+
+   This algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>,
+   based on load average being recomputed once per second, which is
+   (apparently) how Solaris operates.  Linux recomputes only once every 5
+   seconds, but Linux is handled by the /proc/loadavg algorithm above.

-   This implementation of the PWB library alloca function,
-   which is used to allocate space off the run-time stack so
-   that it is automatically reclaimed upon procedure exit,
-   was inspired by discussions with J. Q. Johnson of Cornell.
-   J.Otto Tennant <jot@cray.com> contributed the Cray support.
-
-   There are some preprocessor constants that can
-   be defined when compiling for your specific system, for
-   improved efficiency; however, the defaults should be okay.
-
-   The general concept of this implementation is to keep
-   track of all alloca-allocated blocks, and reclaim any
-   that are found to be deeper in the stack than the current
-   invocation.  This heuristic does not reclaim storage as
-   soon as it becomes invalid, but it will do so eventually.
-
-   As a special case, alloca(0) reclaims storage without
-   allocating any.  It is a good idea to use alloca(0) in
-   your main control loop, etc. to force garbage collection.  */

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ

-                                is unique to HPUX9.  The best way to get the

-                                macro that comes with autoconf 2.13 or newer.
-                                If that isn't an option, then just put
-                                AC_CHECK_FUNCS(pstat_getdynamic) in your
-                                configure.ac file.
-   HAVE_LIBPERFSTAT Define this if your system has the
-                                perfstat_cpu_total function in libperfstat (AIX).
-   FIXUP_KERNEL_SYMBOL_ADDR()   Adjust address in returned struct nlist.
-   KERNEL_FILE                  Name of the kernel file to nlist.
-   LDAV_CVT()                   Scale the load average from the kernel.
-                                Returns a double.
-   LDAV_SYMBOL                  Name of kernel symbol giving load average.
-   LOAD_AVE_TYPE                Type of the load average array in the kernel.
-                                Must be defined unless one of

-   HAVE_NLIST_H                 nlist.h is available.  NLIST_STRUCT defaults
-                                to this.
-   NLIST_STRUCT                 Include nlist.h, not a.out.h.
-   N_NAME_POINTER               The nlist n_name element is a pointer,

-   HAVE_STRUCT_NLIST_N_UN_N_NAME 'n_un.n_name' is member of 'struct nlist'.

-       AC_DEFINE([MSVC_INVALID_PARAMETER_HANDLING], [HAIRY_LIBRARY_HANDLING])

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ

-/* Set up the following warnings, based on which modules are in use.
-   GNU Coding Standards discourage the use of fseek, since it imposes
-   an arbitrary limitation on some 32-bit hosts.  Remember that the
-   fseek module depends on the fseeko module, so we only have three
-   cases to consider:
-
-   1. The developer is not using either module.  Issue a warning under
-   GNULIB_POSIXCHECK for both functions, to remind them that both
-   functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
-   impact on this warning.
-
-   2. The developer is using both modules.  They may be unaware of the
-   arbitrary limitations of fseek, so issue a warning under
-   GNULIB_POSIXCHECK.  On the other hand, they may be using both
-   modules intentionally, so the developer can define
-   _GL_NO_LARGE_FILES in the compilation units where the use of fseek
-   is safe, to silence the warning.
-
-   3. The developer is using the fseeko module, but not fseek.  Gnulib
-   guarantees that fseek will still work around platform bugs in that
-   case, but we presume that the developer is aware of the pitfalls of
-   fseek and was trying to avoid it, so issue a warning even when
-   GNULIB_POSIXCHECK is undefined.  Again, _GL_NO_LARGE_FILES can be
-   defined to silence the warning in particular compilation units.
-   In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
-   fseek gets defined as a macro, it is recommended that the developer
-   uses the fseek module, even if he is not calling the fseek function.
-
-   Most gnulib clients that perform stream operations should fall into
-   category 3.  */

-/* Set up the following warnings, based on which modules are in use.
-   GNU Coding Standards discourage the use of fseek, since it imposes
-   an arbitrary limitation on some 32-bit hosts.  Remember that the
-   fseek module depends on the fseeko module, so we only have three
-   cases to consider:
-
-   1. The developer is not using either module.  Issue a warning under
-   GNULIB_POSIXCHECK for both functions, to remind them that both
-   functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
-   impact on this warning.
-
-   2. The developer is using both modules.  They may be unaware of the
-   arbitrary limitations of fseek, so issue a warning under
-   GNULIB_POSIXCHECK.  On the other hand, they may be using both
-   modules intentionally, so the developer can define
-   _GL_NO_LARGE_FILES in the compilation units where the use of fseek
-   is safe, to silence the warning.
-
-   3. The developer is using the fseeko module, but not fseek.  Gnulib
-   guarantees that fseek will still work around platform bugs in that
-   case, but we presume that the developer is aware of the pitfalls of
-   fseek and was trying to avoid it, so issue a warning even when
-   GNULIB_POSIXCHECK is undefined.  Again, _GL_NO_LARGE_FILES can be
-   defined to silence the warning in particular compilation units.
-   In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
-   fseek gets defined as a macro, it is recommended that the developer
-   uses the fseek module, even if he is not calling the fseek function.
-
-   Most gnulib clients that perform stream operations should fall into
-   category 3.  */

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif

-/* Each of these macros verifies that its argument R is nonzero.  To
-   be portable, R should be an integer constant expression.  Unlike
-   assert (R), there is no run-time overhead.
-
-   If _Static_assert works, verify (R) uses it directly.  Similarly,
-   _GL_VERIFY_TRUE works by packaging a _Static_assert inside a struct
-   that is an operand of sizeof.
-
-   The code below uses several ideas for C++ compilers, and for C
-   compilers that do not support _Static_assert:
-
-   * The first step is ((R) ? 1 : -1).  Given an expression R, of
-     integral or boolean or floating-point type, this yields an
-     expression of integral type, whose value is later verified to be
-     constant and nonnegative.
-
-   * Next this expression W is wrapped in a type
-     struct _gl_verify_type {
-       unsigned int _gl_verify_error_if_negative: W;
-     }.
-     If W is negative, this yields a compile-time error.  No compiler can
-     deal with a bit-field of negative size.
-
-     One might think that an array size check would have the same
-     effect, that is, that the type struct { unsigned int dummy[W]; }
-     would work as well.  However, inside a function, some compilers
-     (such as C++ compilers and GNU C) allow local parameters and
-     variables inside array size expressions.  With these compilers,
-     an array size check would not properly diagnose this misuse of
-     the verify macro:
-
-       void function (int n) { verify (n < 0); }
-
-   * For the verify macro, the struct _gl_verify_type will need to
-     somehow be embedded into a declaration.  To be portable, this
-     declaration must declare an object, a constant, a function, or a
-     typedef name.  If the declared entity uses the type directly,
-     such as in
-
-       struct dummy {...};
-       typedef struct {...} dummy;
-       extern struct {...} *dummy;
-       extern void dummy (struct {...} *);
-       extern struct {...} *dummy (void);
-
-     two uses of the verify macro would yield colliding declarations
-     if the entity names are not disambiguated.  A workaround is to
-     attach the current line number to the entity name:
-
-       #define _GL_CONCAT0(x, y) x##y
-       #define _GL_CONCAT(x, y) _GL_CONCAT0 (x, y)
-       extern struct {...} * _GL_CONCAT (dummy, __LINE__);
-
-     But this has the problem that two invocations of verify from
-     within the same macro would collide, since the __LINE__ value
-     would be the same for both invocations.  (The GCC __COUNTER__
-     macro solves this problem, but is not portable.)
-
-     A solution is to use the sizeof operator.  It yields a number,
-     getting rid of the identity of the type.  Declarations like
-
-       extern int dummy [sizeof (struct {...})];
-       extern void dummy (int [sizeof (struct {...})]);
-       extern int (*dummy (void)) [sizeof (struct {...})];
-
-     can be repeated.
-
-   * Should the implementation use a named struct or an unnamed struct?
-     Which of the following alternatives can be used?
-
-       extern int dummy [sizeof (struct {...})];
-       extern int dummy [sizeof (struct _gl_verify_type {...})];
-       extern void dummy (int [sizeof (struct {...})]);
-       extern void dummy (int [sizeof (struct _gl_verify_type {...})]);
-       extern int (*dummy (void)) [sizeof (struct {...})];
-       extern int (*dummy (void)) [sizeof (struct _gl_verify_type {...})];
-
-     In the second and sixth case, the struct type is exported to the
-     outer scope; two such declarations therefore collide.  GCC warns
-     about the first, third, and fourth cases.  So the only remaining
-     possibility is the fifth case:
-
-       extern int (*dummy (void)) [sizeof (struct {...})];
-
-   * GCC warns about duplicate declarations of the dummy function if
-     -Wredundant-decls is used.  GCC 4.3 and later have a builtin
-     __COUNTER__ macro that can let us generate unique identifiers for
-     each dummy function, to suppress this warning.
-
-   * This implementation exploits the fact that older versions of GCC,
-     which do not support _Static_assert, also do not warn about the
-     last declaration mentioned above.
-
-   * GCC warns if -Wnested-externs is enabled and 'verify' is used
-     within a function body; but inside a function, you can always
-     arrange to use verify_expr instead.
-
-   * In C++, any struct definition inside sizeof is invalid.
-     Use a template type to work around the problem.  */

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }

-
-   Suppress extern inline with HP-UX cc, as it appears to be broken; see
-   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
-
-   Suppress extern inline with Sun C in standards-conformance mode, as it
-   mishandles inline functions that call each other.  E.g., for 'inline void f
-   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
-   'reference to static identifier "f" in extern inline function'.
-   This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
-
-   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
-   on configurations that mistakenly use 'static inline' to implement
-   functions or macros in standard C headers like <ctype.h>.  For example,
-   if isdigit is mistakenly implemented via a static inline function,
-   a program containing an extern inline function that calls isdigit
-   may not work since the C standard prohibits extern inline functions
-   from calling static functions (ISO C 99 section 6.7.4.(3).
-   This bug is known to occur on:
-
-     OS X 10.8 and earlier; see:
-     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
-
-     DragonFly; see
-     http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
-
-     FreeBSD; see:
-     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
-
-   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
-   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
-   Assume DragonFly and FreeBSD will be similar.
-
-   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
-   inline semantics, unless -fgnu89-inline is used.  It defines a macro
-   __GNUC_STDC_INLINE__ to indicate this situation or a macro
-   __GNUC_GNU_INLINE__ to indicate the opposite situation.
-   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
-   semantics but warns, unless -fgnu89-inline is used:
-     warning: C99 inline functions are not supported; using GNU89
-     warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
-   It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

-dnl Macro to add for using GNU gettext.
-
-dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl    default (if it is not specified or empty) is 'no-libtool'.
-dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
-dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
-dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
-dnl    depending on --{enable,disable}-{shared,static} and on the presence of
-dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
-dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
-dnl    implementations (in libc or libintl) without the ngettext() function
-dnl    will be ignored.  If NEEDSYMBOL is specified and is
-dnl    'need-formatstring-macros', then GNU gettext implementations that don't
-dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
-dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value '$(top_builddir)/intl/' is used.
-dnl
-dnl The result of the configuration is one of three cases:
-dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
-dnl    and used.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 2) GNU gettext has been found in the system's C library.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 3) No internationalization, always use English msgid.
-dnl    Catalog format: none
-dnl    Catalog extension: none
-dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
-dnl The use of .gmo is historical (it was needed to avoid overwriting the
-dnl GNU format catalogs when building on a platform with an X/Open gettext),
-dnl but we keep it in order not to force irrelevant filename changes on the
-dnl maintainers.

-dnl Copyright (C) 2002-2020 Free Software Foundation, Inc.
-dnl This file is free software; the Free Software Foundation
-dnl gives unlimited permission to copy and/or distribute it,

-dnl From Bruno Haible and Sam Steingold.
-
-dnl Sets the HOST_CPU variable to the canonical name of the CPU.
-dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
-dnl C language ABI (application binary interface).
-dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
-dnl config.h.
-dnl
-dnl This canonical name can be used to select a particular assembly language
-dnl source file that will interoperate with C code on the given host.
-dnl
-dnl For example:
-dnl * 'i386' and 'sparc' are different canonical names, because code for i386
-dnl   will not run on SPARC CPUs and vice versa. They have different
-dnl   instruction sets.
-dnl * 'sparc' and 'sparc64' are different canonical names, because code for
-dnl   'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
-dnl   contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
-dnl   instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
-dnl   mode, but not both.
-dnl * 'mips' and 'mipsn32' are different canonical names, because they use
-dnl   different argument passing and return conventions for C functions, and
-dnl   although the instruction set of 'mips' is a large subset of the
-dnl   instruction set of 'mipsn32'.
-dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
-dnl   different sizes for the C types like 'int' and 'void *', and although
-dnl   the instruction sets of 'mipsn32' and 'mips64' are the same.
-dnl * The same canonical name is used for different endiannesses. You can
-dnl   determine the endianness through preprocessor symbols:
-dnl   - 'arm': test __ARMEL__.
-dnl   - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
-dnl   - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
-dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
-dnl   (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
-dnl   - Instructions that do not exist on all of these CPUs (cmpxchg,
-dnl     MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
-dnl     assembly language source files use such instructions, you will
-dnl     need to make the distinction.
-dnl   - Speed of execution of the common instruction set is reasonable across
-dnl     the entire family of CPUs. If you have assembly language source files
-dnl     that are optimized for particular CPU types (like GNU gmp has), you
-dnl     will need to make the distinction.

-dnl Sets INCLUDE_NEXT, INCLUDE_NEXT_AS_FIRST_DIRECTIVE, PRAGMA_SYSTEM_HEADER,
-dnl and PRAGMA_COLUMNS.
-dnl
-dnl INCLUDE_NEXT expands to 'include_next' if the compiler supports it, or to
-dnl 'include' otherwise.
-dnl
-dnl INCLUDE_NEXT_AS_FIRST_DIRECTIVE expands to 'include_next' if the compiler
-dnl supports it in the special case that it is the first include directive in
-dnl the given file, or to 'include' otherwise.
-dnl
-dnl PRAGMA_SYSTEM_HEADER can be used in files that contain #include_next,
-dnl so as to avoid GCC warnings when the gcc option -pedantic is used.
-dnl '#pragma GCC system_header' has the same effect as if the file was found
-dnl through the include search path specified with '-isystem' options (as
-dnl opposed to the search path specified with '-I' options). Namely, gcc
-dnl does not warn about some things, and on some systems (Solaris and Interix)
-dnl __STDC__ evaluates to 0 instead of to 1. The latter is an undesired side
-dnl effect; we are therefore careful to use 'defined __STDC__' or '1' instead
-dnl of plain '__STDC__'.
-dnl
-dnl PRAGMA_COLUMNS can be used in files that override system header files, so
-dnl as to avoid compilation errors on HP NonStop systems when the gnulib file
-dnl is included by a system header file that does a "#pragma COLUMNS 80" (which
-dnl has the effect of truncating the lines of that file and all files that it
-dnl includes to 80 columns) and the gnulib file has lines longer than 80
-dnl columns.

-# For each whitespace-separated element in the list of NAMES, define
-# HAVE_RAW_DECL_name if the function has a declaration among INCLUDES
-# even after being undefined as a macro.
-#
-# See warn-on-use.h for some hints on how to poison function names, as
-# well as ideas on poisoning global variables and macros.  NAMES may
-# include global variables, but remember that only functions work with
-# _GL_WARN_ON_USE.  Typically, INCLUDES only needs to list a single
-# header, but if the replacement header pulls in other headers because
-# some systems declare functions in the wrong header, then INCLUDES
-# should do likewise.
-#
-# It is generally safe to assume declarations for functions declared
-# in the intersection of C89 and C11 (such as printf) without
-# needing gl_WARN_ON_USE_PREPARE.

+
+   Read a token.  As long as there's no token available we'll block.  We

+
+   There is one other twist: there is a span between the time reap_children()
+   does its last check for dead children and the time the read(2) call is
+   entered, below, where if a child dies we won't notice.  This is extremely
+   serious as it could cause us to deadlock, given the right set of events.
+
+   To avoid this, we do the following: before we reap_children(), we dup(2)
+   the read FD on the jobserver pipe.  The read(2) call below uses that new
+   FD.  In the signal handler, we close that FD.  That way, if a child dies

-   Suppress extern inline with HP-UX cc, as it appears to be broken; see
-   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
-
-   Suppress extern inline with Sun C in standards-conformance mode, as it
-   mishandles inline functions that call each other.  E.g., for 'inline void f
-   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
-   'reference to static identifier "f" in extern inline function'.
-   This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
-
-   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
-   on configurations that mistakenly use 'static inline' to implement
-   functions or macros in standard C headers like <ctype.h>.  For example,
-   if isdigit is mistakenly implemented via a static inline function,
-   a program containing an extern inline function that calls isdigit
-   may not work since the C standard prohibits extern inline functions
-   from calling static functions (ISO C 99 section 6.7.4.(3).
-   This bug is known to occur on:
-
-     OS X 10.8 and earlier; see:
-     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
-
-     DragonFly; see
-     http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
-
-     FreeBSD; see:
-     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
-
-   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
-   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
-   Assume DragonFly and FreeBSD will be similar.
-
-   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
-   inline semantics, unless -fgnu89-inline is used.  It defines a macro
-   __GNUC_STDC_INLINE__ to indicate this situation or a macro
-   __GNUC_GNU_INLINE__ to indicate the opposite situation.
-   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
-   semantics but warns, unless -fgnu89-inline is used:
-     warning: C99 inline functions are not supported; using GNU89
-     warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
-   It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

-   Suppress extern inline with HP-UX cc, as it appears to be broken; see
-   <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
-
-   Suppress extern inline with Sun C in standards-conformance mode, as it
-   mishandles inline functions that call each other.  E.g., for 'inline void f
-   (void) { } inline void g (void) { f (); }', c99 incorrectly complains
-   'reference to static identifier "f" in extern inline function'.
-   This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
-
-   Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
-   on configurations that mistakenly use 'static inline' to implement
-   functions or macros in standard C headers like <ctype.h>.  For example,
-   if isdigit is mistakenly implemented via a static inline function,
-   a program containing an extern inline function that calls isdigit
-   may not work since the C standard prohibits extern inline functions
-   from calling static functions (ISO C 99 section 6.7.4.(3).
-   This bug is known to occur on:
-
-     OS X 10.8 and earlier; see:
-     https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
-
-     DragonFly; see
-     http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
-
-     FreeBSD; see:
-     https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
-
-   OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
-   for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
-   Assume DragonFly and FreeBSD will be similar.
-
-   GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
-   inline semantics, unless -fgnu89-inline is used.  It defines a macro
-   __GNUC_STDC_INLINE__ to indicate this situation or a macro
-   __GNUC_GNU_INLINE__ to indicate the opposite situation.
-   GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
-   semantics but warns, unless -fgnu89-inline is used:
-     warning: C99 inline functions are not supported; using GNU89
-     warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
-   It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

-/* Determine if the load average on the system is too high to start a new job.
-
-   On systems which provide /proc/loadavg (e.g., Linux), we use an idea
-   provided by Sven C. Dack <sven.c.dack@sky.com>: retrieve the current number
-   of processes the kernel is running and, if it's greater than the requested
-   load we don't allow another job to start.  We allow a job to start with
-   equal processes since one of those will be for make itself, which will then
-   pause waiting for jobs to clear.
-
-   Otherwise, we obtain the system load average and compare that.
-
-   The system load average is only recomputed once every N (N>=1) seconds.
-   However, a very parallel make can easily start tens or even hundreds of
-   jobs in a second, which brings the system to its knees for a while until
-   that first batch of jobs clears out.
-
-   To avoid this we use a weighted algorithm to try to account for jobs which
-   have been started since the last second, and guess what the load average
-   would be now if it were computed.
-
-   This algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>,
-   based on load average being recomputed once per second, which is
-   (apparently) how Solaris operates.  Linux recomputes only once every 5
-   seconds, but Linux is handled by the /proc/loadavg algorithm above.

-
-!      calculate something load-oid and add to the observed sys.load,
-!      so that latter can catch up:
-!      - every job started increases jobctr;
-!      - every dying job decreases a positive jobctr;
-!      - the jobctr value gets zeroed every change of seconds,
-!        after its value*weight_b is stored into the 'backlog' value last_sec
-!      - weight_a times the sum of jobctr and last_sec gets
-!        added to the observed sys.load.
-!
-!      The two weights have been tried out on 24 and 48 proc. Sun Solaris-9
-!      machines, using a several-thousand-jobs-mix of cpp, cc, cxx and smallish
-!      sub-shelled commands (rm, echo, sed...) for tests.
-!      lowering the 'direct influence' factor weight_a (e.g. to 0.1)
-!      resulted in significant excession of the load limit, raising it
-!      (e.g. to 0.5) took bad to small, fast-executing jobs and didn't
-!      reach the limit in most test cases.
-!
-!      lowering the 'history influence' weight_b (e.g. to 0.1) resulted in

-/* This method uses a "traditional" UNIX model for waiting on both a signal

-   handler installed we need to check ALL system calls for EINTR: painful!
-
-   Read a token.  As long as there's no token available we'll block.  We
-   enable interruptible system calls before the read(2) so that if we get a
-   SIGCHLD while we're waiting, we'll return with EINTR and we can process the
-   death(s) and return tokens to the free pool.
-
-   Once we return from the read, we immediately reinstate restartable system
-   calls.  This allows us to not worry about checking for EINTR on all the
-   other system calls in the program.
-
-   There is one other twist: there is a span between the time reap_children()
-   does its last check for dead children and the time the read(2) call is
-   entered, below, where if a child dies we won't notice.  This is extremely
-   serious as it could cause us to deadlock, given the right set of events.
-
-   To avoid this, we do the following: before we reap_children(), we dup(2)
-   the read FD on the jobserver pipe.  The read(2) call below uses that new
-   FD.  In the signal handler, we close that FD.  That way, if a child dies
-   during the section mentioned above, the read(2) will be invoked with an
-   invalid FD and will return immediately with EBADF.  */

-/* File: vms_progname.c
- *
- * This module provides a fixup of the program name.
- *
- * This module is designed to be a plug in replacement for the
- * progname module used by many GNU utilities with a few enhancements
- * needed for GNU Make.
- *
- * It does not support the HAVE_DECL_PROGRAM_INVOCATION_* macros at this
- * time.
- *
- * Make sure that the program_name string is set as close as possible to
- *    what the original command was given.
- *
- * When run from DCL, The argv[0] element is initialized with an absolute
- * path name.  The decc$ feature logical names can control the format
- * of this pathname.  In some cases it causes the UNIX format name to be
- * formatted incorrectly.
- *
- * This DCL provided name is usually incompatible with what is expected to
- * be provided by Unix programs and needs to be replaced.
- *
- * When run from an exec() call, the argv[0] element is initialized by the
- * program.  This name is compatible with what is expected to be provided
- * by Unix programs and should be passed through unchanged.
- *
- * The DCL provided name can be detected because it always contains the
- * device name.
- *
- * DCL examples:
- *    devname:[dir]program.exe;1         Normal VMS - remove path and .EXE;n
- *    devname:[dir]facility$program.exe;1   Facility also needs removal.
- *    /devname/dir/program.exe
- *    /DISK$VOLUME/dir/program.exe.1     Bug version should not be there.
- *    /DISK$VOLUME/dir/program.          Bug Period should not be there.

-   * Code to make ctrl+c and ctrl+y working.
-   * The problem starts with the synchronous case where after lib$spawn is
-   * called any input will go to the child. But with input re-directed,
-   * both control characters won't make it to any of the programs, neither
-   * the spawning nor to the spawned one. Hence the caller needs to spawn
-   * with CLI$M_NOWAIT to NOT give up the input focus. A sys$waitfr
-   * has to follow to simulate the wanted synchronous behaviour.
-   * The next problem is ctrl+y which isn't caught by the crtl and
-   * therefore isn't converted to SIGQUIT (for a signal handler which is
-   * already established). The only way to catch ctrl+y, is an AST
-   * assigned to the input channel. But ctrl+y handling of DCL needs to be
-   * disabled, otherwise it will handle it. Not to mention the previous
-   * ctrl+y handling of DCL needs to be re-established before make exits.
-   * One more: At the time of LIB$SPAWN signals are blocked. SIGQUIT will
-   * make it to the signal handler after the child "normally" terminates.
-   * This isn't enough. It seems reasonable for simple command lines like
-   * a 'cc foobar.c' spawned in a subprocess but it is unacceptable for
-   * spawning make. Therefore we need to abort the process in the AST.
-   *
-   * Prior to the spawn it is checked if an AST is already set up for
-   * ctrl+y, if not one is set up for a channel to SYS$COMMAND. In general
-   * this will work except if make is run in a batch environment, but there
-   * nobody can press ctrl+y. During the setup the DCL handling of ctrl+y
-   * is disabled and an exit handler is established to re-enable it.
-   * If the user interrupts with ctrl+y, the assigned AST will fire, force
-   * an abort to the subprocess and signal SIGQUIT, which will be caught by
-   * the already established handler and will bring us back to common code.
-   * After the spawn (now /nowait) a sys$waitfr simulates the /wait and
-   * enables the ctrl+y be delivered to this code. And the ctrl+c too,
-   * which the crtl converts to SIGINT and which is caught by the common
-   * signal handler. Because signals were blocked before entering this code
-   * sys$waitfr will always complete and the SIGQUIT will be processed after
-   * it (after termination of the current block, somewhere in common code).
-   * And SIGINT too will be delayed. That is ctrl+c can only abort when the
-   * current command completes. Anyway it's better than nothing :-)

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+   for FUNCTION which will then trigger a compiler warning containing
+   the text of "literal string" anywhere that function is called, if
+   supported by the compiler.  If the compiler does not support this
+   feature, the macro expands to an unused extern declaration.
+
+   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
+   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
+   this feature, it expands to empty.
+
+   These macros are useful for marking a function as a potential
+   portability trap, with the intent that "literal string" include
+   instructions on the replacement function that should be used
+   instead.
+   _GL_WARN_ON_USE is for functions with 'extern' linkage.
+   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
+   linkage.
+
+   However, one of the reasons that a function is a portability trap is
+   if it has the wrong signature.  Declaring FUNCTION with a different
+   signature in C is a compilation error, so this macro must use the
+   same type as any existing declaration so that programs that avoid
+   the problematic FUNCTION do not fail to compile merely because they
+   included a header that poisoned the function.  But this implies that
+   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
+   have a declaration.  Use of this macro implies that there must not
+   be any other macro hiding the declaration of FUNCTION; but
+   undefining FUNCTION first is part of the poisoning process anyway
+   (although for symbols that are provided only via a macro, the result
+   is a compilation error rather than a warning containing
+   "literal string").  Also note that in C++, it is only safe to use if
+   FUNCTION has no overloads.
+
+   For an example, it is possible to poison 'getline' by:
+        [getline]) in configure.ac, which potentially defines
+     HAVE_RAW_DECL_GETLINE
+   - adding this code to a header that wraps the system <stdio.h>:
+     #undef getline
+     #if HAVE_RAW_DECL_GETLINE
+     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+       "not universally present; use the gnulib module getline");
+     #endif
+
+   It is not possible to directly poison global variables.  But it is
+   possible to write a wrapper accessor function, and poison that
+   (less common usage, like &environ, will cause a compilation error
+   rather than issue the nice warning, but the end result of informing
+   the developer about their portability problem is still achieved):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     rpl_environ (void) { return &environ; }
+     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
+     # undef environ
+     # define environ (*rpl_environ ())
+     #endif
+   or better (avoiding contradictory use of 'static' and 'extern'):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
+     rpl_environ (void) { return &environ; }

+/* Set up the following warnings, based on which modules are in use.
+   GNU Coding Standards discourage the use of fseek, since it imposes
+   an arbitrary limitation on some 32-bit hosts.  Remember that the
+   fseek module depends on the fseeko module, so we only have three
+   cases to consider:
+
+   1. The developer is not using either module.  Issue a warning under
+   GNULIB_POSIXCHECK for both functions, to remind them that both
+   functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
+   impact on this warning.
+
+   2. The developer is using both modules.  They may be unaware of the
+   arbitrary limitations of fseek, so issue a warning under
+   GNULIB_POSIXCHECK.  On the other hand, they may be using both
+   modules intentionally, so the developer can define
+   _GL_NO_LARGE_FILES in the compilation units where the use of fseek
+   is safe, to silence the warning.
+
+   3. The developer is using the fseeko module, but not fseek.  Gnulib

+/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
+   for FUNCTION which will then trigger a compiler warning containing
+   the text of "literal string" anywhere that function is called, if
+   supported by the compiler.  If the compiler does not support this
+   feature, the macro expands to an unused extern declaration.
+
+   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
+   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
+   this feature, it expands to empty.
+
+   These macros are useful for marking a function as a potential
+   portability trap, with the intent that "literal string" include
+   instructions on the replacement function that should be used
+   instead.
+   _GL_WARN_ON_USE is for functions with 'extern' linkage.
+   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
+   linkage.
+
+   However, one of the reasons that a function is a portability trap is
+   if it has the wrong signature.  Declaring FUNCTION with a different
+   signature in C is a compilation error, so this macro must use the
+   same type as any existing declaration so that programs that avoid
+   the problematic FUNCTION do not fail to compile merely because they
+   included a header that poisoned the function.  But this implies that
+   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
+   have a declaration.  Use of this macro implies that there must not
+   be any other macro hiding the declaration of FUNCTION; but
+   undefining FUNCTION first is part of the poisoning process anyway
+   (although for symbols that are provided only via a macro, the result
+   is a compilation error rather than a warning containing
+   "literal string").  Also note that in C++, it is only safe to use if
+   FUNCTION has no overloads.
+
+   For an example, it is possible to poison 'getline' by:
+        [getline]) in configure.ac, which potentially defines
+     HAVE_RAW_DECL_GETLINE
+   - adding this code to a header that wraps the system <stdio.h>:
+     #undef getline
+     #if HAVE_RAW_DECL_GETLINE
+     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
+       "not universally present; use the gnulib module getline");
+     #endif
+
+   It is not possible to directly poison global variables.  But it is
+   possible to write a wrapper accessor function, and poison that
+   (less common usage, like &environ, will cause a compilation error
+   rather than issue the nice warning, but the end result of informing
+   the developer about their portability problem is still achieved):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     rpl_environ (void) { return &environ; }
+     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
+     # undef environ
+     # define environ (*rpl_environ ())
+     #endif
+   or better (avoiding contradictory use of 'static' and 'extern'):
+     #if HAVE_RAW_DECL_ENVIRON
+     static char ***
+     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
+     rpl_environ (void) { return &environ; }

-The test suite was originally written by Steve McGee and Chris Arthur.
-It is covered by the GNU General Public License (Version 2), described
-in the file COPYING.  It has been maintained as part of GNU make proper
-since GNU make 3.78.
-
-This entire test suite, including all test files, are copyright and
-distributed under the following terms:
-
- -----------------------------------------------------------------------------
- Copyright (C) 1992-2020 Free Software Foundation, Inc.
- This file is part of GNU Make.
-
- GNU Make is free software; you can redistribute it and/or modify it under the
- terms of the GNU General Public License as published by the Free Software

- version.
-

-

- -----------------------------------------------------------------------------
-
-The test suite requires Perl.  These days, you should have at least Perl
-5.004 (available from ftp.gnu.org, and portable to many machines).  It
-used to work with Perl 4.036 but official support for Perl 4.x was
-abandoned a long time ago, due to lack of testbeds, as well as interest.
-
-The test suite assumes that the first "diff" it finds on your PATH is
-GNU diff, but that only matters if a test fails.
-
-To run the test suite on a UNIX system, use "perl ./run_make_tests"
-(or just "./run_make_tests" if you have a perl on your PATH).
-
-To run the test suite on Windows NT or DOS systems, use
-"perl.exe ./run_make-tests.pl".
-
-By default, the test engine picks up the first executable called "make"
-that it finds in your path.  You may use the -make_path option (i.e.,
-"perl run_make_tests -make_path /usr/local/src/make-3.78/make") if
-you want to run a particular copy.  This now works correctly with
-relative paths and when make is called something other than "make" (like
-"gmake").
-
-Tests cannot end with a "~" character, as the test suite will ignore any
-that do (I was tired of having it run my Emacs backup files as tests :))
-
-Also, sometimes the tests may behave strangely on networked
-filesystems.  You can use mkshadow to create a copy of the test suite in
-/tmp or similar, and try again.  If the error disappears, it's an issue
-with your network or file server, not GNU make (I believe).  This
-shouldn't happen very often anymore: I've done a lot of work on the
-tests to reduce the impacts of this situation.
-
-The options/dash-l test will not really test anything if the copy of
-make you are using can't obtain the system load.  Some systems require
-make to be setgid sys or kmem for this; if you don't want to install
-make just to test it, make it setgid to kmem or whatever group /dev/kmem
-is (i.e., "chgrp kmem make;chmod g+s make" as root).  In any case, the
-options/dash-l test should no longer *fail* because make can't read
-/dev/kmem.
-
-A directory named "work" will be created when the tests are run which
-will contain any makefiles and "diff" files of tests that fail so that
-you may look at them afterward to see the output of make and the
-expected result.
-
-There is a -help option which will give you more information about the
-other possible options for the test suite.
-
-
-Open Issues
------------
-
-The test suite has a number of problems which should be addressed.  One
-VERY serious one is that there is no real documentation.  You just have
-to see the existing tests.  Use the newer tests: many of the tests
-haven't been updated to use the latest/greatest test methods.  See the
-ChangeLog in the tests directory for pointers.
-
-The second serious problem is that it's not parallelizable: it scribbles
-all over its installation directory and so can only test one make at a
-time.  The third serious problem is that it's not relocatable: the only
-way it works when you build out of the source tree is to create
-symlinks, which doesn't work on every system and is bogus to boot.  The
-fourth serious problem is that it doesn't create its own sandbox when
-running tests, so that if a test forgets to clean up after itself that
-can impact future tests.
-
-
-Bugs
-----
-
-Any complaints/suggestions/bugs/etc. for the test suite itself (as
-opposed to problems in make that the suite finds) should be handled the
-same way as normal GNU make bugs/problems (see the README for GNU make).

-we give make the -n option.  We now expect the command to be

-# -------------------------
-# Make sure that prefix characters apply properly to define/endef values.
-#
-# There's a bit of oddness here if you try to use a variable to hold the
-# prefix character for a define.  Even though something like this:
-#
-#       define foo
-#       echo bar
-#       endef
-#
-#       all: ; $(V)$(foo)
-#
-# (where V=@) can be seen by the user to be obviously different than this:
-#
-#       define foo
-#       $(V)echo bar
-#       endef
-#
-#       all: ; $(foo)
-#
-# and the user thinks it should behave the same as when the "@" is literal
-# instead of in a variable, that can't happen because by the time make
-# expands the variables for the command line and sees it begins with a "@" it
-# can't know anymore whether the prefix character came before the variable
-# reference or was included in the first line of the variable reference.

+Zip stores files in zip archives.  The default action is to add or replace\n\
+zipfile entries.\n\
+\n\
+Basic command line:\n\
+  zip options archive_name file file ...\n\
+\n\
+Some examples:\n\
+  Add file.txt to z.zip (create z if needed):      zip z file.txt\n\
+  Zip all files in current dir:                    zip z *\n\
+  Zip files in current dir and subdirs also:       zip -r z .\n\
+\n\
+Basic modes:\n\
+ External modes (selects files from file system):\n\
+        add      - add new files/update existing files in archive (default)\n\
+  -u    update   - add new files/update existing files only if later date\n\
+  -f    freshen  - update existing files only (no files added)\n\
+  -FS   filesync - update if date or size changed, delete if no OS match\n\
+ Internal modes (selects entries in archive):\n\
+  -d    delete   - delete files from archive (see below)\n\
+  -U    copy     - select files in archive to copy (use with --out)\n\
+\n\
+Basic options:\n\
+  -r        recurse into directories (see Recursion below)\n\
+  -m        after archive created, delete original files (move into archive)\n\
+  -j        junk directory names (store just file names)\n\
+  -q        quiet operation\n\
+  -v        verbose operation (just \"zip -v\" shows version information)\n\
+  -c        prompt for one-line comment for each entry\n\
+  -z        prompt for comment for archive (end with just \".\" line or EOF)\n\
+  -@        read names to zip from stdin (one path per line)\n\
+  -o        make zipfile as old as latest entry\n\
+\n\
+\n\
+Syntax:\n\
+  The full command line syntax is:\n\
+\n\
+    zip [-shortopts ...] [--longopt ...] [zipfile [path path ...]] [-xi list]\n\
+\n\
+  Any number of short option and long option arguments are allowed\n\
+  (within limits) as well as any number of path arguments for files\n\
+  to zip up.  If zipfile exists, the archive is read in.  If zipfile\n\
+  is \"-\", stream to stdout.  If any path is \"-\", zip stdin.\n\
+\n\
+Options and Values:\n\
+  For short options that take values, use -ovalue or -o value or -o=value\n\
+  For long option values, use either --longoption=value or --longoption value\n\
+  For example:\n\
+    zip -ds 10 --temp-dir=path zipfile path1 path2 --exclude pattern pattern\n\
+  Avoid -ovalue (no space between) to avoid confusion\n\
+  In particular, be aware of 2-character options.  For example:\n\
+    -d -s is (delete, split size) while -ds is (dot size)\n\
+  Usually better to break short options across multiple arguments by function\n\
+    zip -r -dbdcds 10m -lilalf logfile archive input_directory -ll\n\
+\n\
+  All args after just \"--\" arg are read verbatim as paths and not options.\n\
+    zip zipfile path path ... -- verbatimpath verbatimpath ...\n\
+  Use -nw to also disable wildcards, so paths are read literally:\n\
+    zip zipfile -nw -- \"-leadingdashpath\" \"a[path].c\" \"path*withwildcard\"\n\
+  You may still have to escape or quote arguments to avoid shell expansion\n\
+\n\
+Wildcards:\n\
+  Internally zip supports the following wildcards:\n\
+    ?       (or %% or #, depending on OS) matches any single character\n\
+    *       matches any number of characters, including zero\n\
+    [list]  matches char in list (regex), can do range [ac-f], all but [!bf]\n\
+  If port supports [], must escape [ as [[] or use -nw to turn off wildcards\n\
+  For shells that expand wildcards, escape (\\* or \"*\") so zip can recurse\n\
+    zip zipfile -r . -i \"*.h\"\n\
+\n\
+  Normally * crosses dir bounds in path, e.g. 'a*b' can match 'ac/db'.  If\n\
+   -ws option used, * does not cross dir bounds but ** does\n\
+\n\
+  For DOS and Windows, [list] is now disabled unless the new option\n\
+  -RE       enable [list] (regular expression) matching\n\
+  is used to avoid problems with file paths containing \"[\" and \"]\":\n\
+    zip files_ending_with_number -RE foo[0-9].c\n\
+\n\
+Include and Exclude:\n\
+  -i pattern pattern ...   include files that match a pattern\n\
+  -x pattern pattern ...   exclude files that match a pattern\n\
+  Patterns are paths with optional wildcards and match paths as stored in\n\
+  archive.  Exclude and include lists end at next option, @, or end of line.\n\
+    zip -x pattern pattern @ zipfile path path ...\n\
+\n\
+Case matching:\n\
+  On most OS the case of patterns must match the case in the archive, unless\n\
+  the -ic option is used.\n\
+  -ic       ignore case of archive entries\n\
+  This option not available on case-sensitive file systems.  On others, case\n\
+  ignored when matching files on file system but matching against archive\n\
+  entries remains case sensitive for modes -f (freshen), -U (archive copy),\n\
+  and -d (delete) because archive paths are always case sensitive.  With\n\
+  -ic, all matching ignores case, but it's then possible multiple archive\n\
+  entries that differ only in case will match.\n\
+\n\
+End Of Line Translation (text files only):\n\
+  -l        change CR or LF (depending on OS) line end to CR LF (Unix->Win)\n\
+  -ll       change CR LF to CR or LF (depending on OS) line end (Win->Unix)\n\
+  If first buffer read from file contains binary the translation is skipped\n\
+\n\
+Recursion:\n\
+  -r        recurse paths, include files in subdirs:  zip -r a path path ...\n\
+  -R        recurse current dir and match patterns:   zip -R a ptn ptn ...\n\
+  Use -i and -x with either to include or exclude paths\n\
+  Path root in archive starts at current dir, so if /a/b/c/file and\n\
+   current dir is /a/b, 'zip -r archive .' puts c/file in archive\n\
+\n\
+Date filtering:\n\
+  -t date   exclude before (include files modified on this date and later)\n\
+  -tt date  include before (include files modified before date)\n\
+  Can use both at same time to set a date range\n\
+  Dates are mmddyyyy or yyyy-mm-dd\n\
+\n\
+Deletion, File Sync:\n\
+  -d        delete files\n\
+  Delete archive entries matching internal archive paths in list\n\
+    zip archive -d pattern pattern ...\n\
+  Can use -t and -tt to select files in archive, but NOT -x or -i, so\n\
+    zip archive -d \"*\" -t 2005-12-27\n\
+  deletes all files from archive.zip with date of 27 Dec 2005 and later\n\
+  Note the * (escape as \"*\" on Unix) to select all files in archive\n\
+\n\
+  -FS       file sync\n\
+  Similar to update, but files updated if date or size of entry does not\n\
+  match file on OS.  Also deletes entry from archive if no matching file\n\
+  on OS.\n\
+    zip archive_to_update -FS -r dir_used_before\n\
+  Result generally same as creating new archive, but unchanged entries\n\
+  are copied instead of being read and compressed so can be faster.\n\
+      WARNING:  -FS deletes entries so make backup copy of archive first\n\
+\n\
+Compression:\n\
+  -0        store files (no compression)\n\
+  -1 to -9  compress fastest to compress best (default is 6)\n\
+  -Z cm     set compression method to cm:\n\
+              store   - store without compression, same as option -0\n\
+              deflate - original zip deflate, same as -1 to -9 (default)\n\
+              bzip2 - use bzip2 compression (need modern unzip)\n\
+\n\
+Encryption:\n\
+  -e        use standard (weak) PKZip 2.0 encryption, prompt for password\n\
+  -P pswd   use standard encryption, password is pswd\n\
+\n\
+Splits (archives created as a set of split files):\n\
+  -s ssize  create split archive with splits of size ssize, where ssize nm\n\
+              n number and m multiplier (kmgt, default m), 100k -> 100 kB\n\
+  -sp       pause after each split closed to allow changing disks\n\
+      WARNING:  Archives created with -sp use data descriptors and should\n\
+                work with most unzips but may not work with some\n\
+  -sb       ring bell when pause\n\
+  -sv       be verbose about creating splits\n\
+      Split archives CANNOT be updated, but see --out and Copy Mode below\n\
+\n\
+Using --out (output to new archive):\n\
+  --out oa  output to new archive oa\n\
+  Instead of updating input archive, create new output archive oa.\n\
+  Result is same as without --out but in new archive.  Input archive\n\
+  unchanged.\n\
+      WARNING:  --out ALWAYS overwrites any existing output file\n\
+  For example, to create new_archive like old_archive but add newfile1\n\
+  and newfile2:\n\
+    zip old_archive newfile1 newfile2 --out new_archive\n\
+  Cannot update split archive, so use --out to out new archive:\n\
+    zip in_split_archive newfile1 newfile2 --out out_split_archive\n\
+  If input is split, output will default to same split size\n\
+  Use -s=0 or -s- to turn off splitting to convert split to single file:\n\
+    zip in_split_archive -s 0 --out out_single_file_archive\n\
+      WARNING:  If overwriting old split archive but need less splits,\n\
+                old splits not overwritten are not needed but remain\n\
+\n\
+Copy Mode (copying from archive to archive):\n\
+  -U        (also --copy) select entries in archive to copy (reverse delete)\n\
+  Copy Mode copies entries from old to new archive with --out and is used by\n\
+  zip when either no input files on command line or -U (--copy) used.\n\
+    zip inarchive --copy pattern pattern ... --out outarchive\n\
+  To copy only files matching *.c into new archive, excluding foo.c:\n\
+    zip old_archive --copy \"*.c\" --out new_archive -x foo.c\n\
+  If no input files and --out, copy all entries in old archive:\n\
+    zip old_archive --out new_archive\n\
+\n\
+Streaming and FIFOs:\n\
+  prog1 | zip -ll z -      zip output of prog1 to zipfile z, converting CR LF\n\
+  zip - -R \"*.c\" | prog2   zip *.c files in current dir and stream to prog2 \n\
+  prog1 | zip | prog2      zip in pipe with no in or out acts like zip - -\n\
+  If Zip is Zip64 enabled, streaming stdin creates Zip64 archives by default\n\
+   that need PKZip 4.5 unzipper like UnZip 6.0\n\
+  WARNING:  Some archives created with streaming use data descriptors and\n\
+            should work with most unzips but may not work with some\n\
+  Can use -fz- to turn off Zip64 if input not large (< 4 GB):\n\
+    prog_with_small_output | zip archive -fz-\n\
+\n\
+  Zip now can read Unix FIFO (named pipes).  Off by default to prevent zip\n\
+  from stopping unexpectedly on unfed pipe, use -FI to enable:\n\
+    zip -FI archive fifo\n\
+\n\
+Dots, counts:\n\
+  -db       display running count of bytes processed and bytes to go\n\
+              (uncompressed size, except delete and copy show stored size)\n\
+  -dc       display running count of entries done and entries to go\n\
+  -dd       display dots every 10 MB (or dot size) while processing files\n\
+  -dg       display dots globally for archive instead of for each file\n\
+    zip -qdgds 10m   will turn off most output except dots every 10 MB\n\
+  -ds siz   each dot is siz processed where siz is nm as splits (0 no dots)\n\
+  -du       display original uncompressed size for each entry as added\n\
+  -dv       display volume (disk) number in format in_disk>out_disk\n\
+  Dot size is approximate, especially for dot sizes less than 1 MB\n\
+  Dot options don't apply to Scanning files dots (dot/2sec) (-q turns off)\n\
+\n\
+Logging:\n\
+  -lf path  open file at path as logfile (overwrite existing file)\n\
+  -la       append to existing logfile\n\
+  -li       include info messages (default just warnings and errors)\n\
+\n\
+Testing archives:\n\
+  -T        test completed temp archive with unzip before updating archive\n\
+  -TT cmd   use command cmd instead of 'unzip -tqq' to test archive\n\
+             On Unix, to use unzip in current directory, could use:\n\
+               zip archive file1 file2 -T -TT \"./unzip -tqq\"\n\
+             In cmd, {} replaced by temp archive path, else temp appended.\n\
+             The return code is checked for success (0 on Unix)\n\
+\n\
+Fixing archives:\n\
+  -F        attempt to fix a mostly intact archive (try this first)\n\
+  -FF       try to salvage what can (may get more but less reliable)\n\
+  Fix options copy entries from potentially bad archive to new archive.\n\
+  -F tries to read archive normally and copy only intact entries, while\n\
+  -FF tries to salvage what can and may result in incomplete entries.\n\
+  Must use --out option to specify output archive:\n\
+    zip -F bad.zip --out fixed.zip\n\
+  Use -v (verbose) with -FF to see details:\n\
+    zip reallybad.zip -FF -v --out fixed.zip\n\
+  Currently neither option fixes bad entries, as from text mode ftp get.\n\
+\n\
+Difference mode:\n\
+  -DF       (also --dif) only include files that have changed or are\n\
+             new as compared to the input archive\n\
+  Difference mode can be used to create incremental backups.  For example:\n\
+    zip --dif full_backup.zip -r somedir --out diff.zip\n\
+  will store all new files, as well as any files in full_backup.zip where\n\
+  either file time or size have changed from that in full_backup.zip,\n\
+  in new diff.zip.  Output archive not excluded automatically if exists,\n\
+  so either use -x to exclude it or put outside what is being zipped.\n\
+\n\
+DOS Archive bit (Windows only):\n\
+  -AS       include only files with the DOS Archive bit set\n\
+  -AC       after archive created, clear archive bit of included files\n\
+      WARNING: Once the archive bits are cleared they are cleared\n\
+               Use -T to test the archive before the bits are cleared\n\
+               Can also use -sf to save file list before zipping files\n\
+\n\
+Show files:\n\
+  -sf       show files to operate on and exit (-sf- logfile only)\n\
+  -su       as -sf but show escaped UTF-8 Unicode names also if exist\n\
+  -sU       as -sf but show escaped UTF-8 Unicode names instead\n\
+  Any character not in the current locale is escaped as #Uxxxx, where x\n\
+  is hex digit, if 16-bit code is sufficient, or #Lxxxxxx if 24-bits\n\
+  are needed.  If add -UN=e, Zip escapes all non-ASCII characters.\n\
+\n\
+Unicode:\n\
+  If compiled with Unicode support, Zip stores UTF-8 path of entries.\n\
+  This is backward compatible.  Unicode paths allow better conversion\n\
+  of entry names between different character sets.\n\
+\n\
+  New Unicode extra field includes checksum to verify Unicode path\n\
+  goes with standard path for that entry (as utilities like ZipNote\n\
+  can rename entries).  If these do not match, use below options to\n\
+  set what Zip does:\n\
+      -UN=Quit     - if mismatch, exit with error\n\
+      -UN=Warn     - if mismatch, warn, ignore UTF-8 (default)\n\
+      -UN=Ignore   - if mismatch, quietly ignore UTF-8\n\
+      -UN=No       - ignore any UTF-8 paths, use standard paths for all\n\
+  An exception to -UN=N are entries with new UTF-8 bit set (instead\n\
+  of using extra fields).  These are always handled as Unicode.\n\
+\n\
+  Normally Zip escapes all chars outside current char set, but leaves\n\
+  as is supported chars, which may not be OK in path names.  -UN=Escape\n\
+  escapes any character not ASCII:\n\
+    zip -sU -UN=e archive\n\
+  Can use either normal path or escaped Unicode path on command line\n\
+  to match files in archive.\n\
+\n\
+  Zip now stores UTF-8 in entry path and comment fields on systems\n\
+  where UTF-8 char set is default, such as most modern Unix, and\n\
+  and on other systems in new extra fields with escaped versions in\n\
+  entry path and comment fields for backward compatibility.\n\
+  Option -UN=UTF8 will force storing UTF-8 in entry path and comment\n\
+  fields:\n\
+      -UN=UTF8     - store UTF-8 in entry path and comment fields\n\
+  This option can be useful for multi-byte char sets on Windows where\n\
+  escaped paths and comments can be too long to be valid as the UTF-8\n\
+  versions tend to be shorter.\n\
+\n\
+  Only UTF-8 comments on UTF-8 native systems supported.  UTF-8 comments\n\
+  for other systems planned in next release.\n\
+\n\
+Self extractor:\n\
+  -A        Adjust offsets - a self extractor is created by prepending\n\
+             the extractor executable to archive, but internal offsets\n\
+             are then off.  Use -A to fix offsets.\n\
+  -J        Junk sfx - removes prepended extractor executable from\n\
+             self extractor, leaving a plain zip archive.\n\
+\n\
+More option highlights (see manual for additional options and details):\n\
+  -b dir    when creating or updating archive, create the temp archive in\n\
+             dir, which allows using seekable temp file when writing to a\n\
+             write once CD, such archives compatible with more unzips\n\
+             (could require additional file copy if on another device)\n\
+  -MM       input patterns must match at least one file and matched files\n\
+             must be readable or exit with OPEN error and abort archive\n\
+             (without -MM, both are warnings only, and if unreadable files\n\
+             are skipped OPEN error (18) returned after archive created)\n\
+  -nw       no wildcards (wildcards are like any other character)\n\
+  -sc       show command line arguments as processed and exit\n\
+  -sd       show debugging as Zip does each step\n\
+  -so       show all available options on this system\n\
+  -X        default=strip old extra fields, -X- keep old, -X strip most\n\
+  -ws       wildcards don't span directory boundaries in paths\n\
+");
+  exit(0);

- * We want all storage to be thread-local storage. So we change
- * RIP-relative instructions to be RBX-relative, only when they
- * reference sections in the binary mutable after initialization.

  * Compress read-only data sections of particularly low entropy, using

+  Your redbean displays a Read-Eval-Print-Loop that lets you modify the
+  state of the main server process while your server is running. Any
+  changes will propagate into forked clients.
 
-   /.init.lua
-           This script is run once in the main process at startup. This lets
-           you modify the state of the Lua interpreter before connection
-           processes are forked off. For example, it's a good idea to do
-           expensive one-time computations here. You can also use this file
-           to call the ProgramFOO() functions below. The init module load
-           happens after redbean's arguments and zip assets have been parsed,
-           but before calling functions like socket() and fork(). Note that
-           this path is a hidden file so that it can't be unintentionally run
-           by the network client.
+  Your REPL is displayed only when redbean is run as a non-daemon in a

+  the REPL is a Lua REPL it's not included in a redbean-static builds.
 
-   /.reload.lua
-           This script is run from the main process when SIGHUP is received.
-           This only applies to redbean when running in daemon mode. Any
-           changes that are made to the Lua interpreter state will be
-           inherited by future forked connection processes. Note that this
-           path is a hidden file so that it can't be unintentionally run by
-           the network client.
+  redbean uses the same keyboard shortcuts as GNU Readline and Emacs.
+  Some of its keyboard commands (listed in a previous section) were
+  inspired by Paredit.
 
-   /.lua/...
-           Your Lua modules go in this directory. The way it works is redbean
-           sets Lua's package.path to /zip/.lua/?.lua;/zip/.lua/?/init.lua by
-           default. Cosmopolitan Libc lets system calls like open read from
-           the ZIP structure, if the filename is prefixed with /zip/. So this
-           works like magic.
+  A history of your commands is saved to `~/.redbean_history`.

-           If it exists, it'll be used as the / listing page icon, embedded
-           as a base64 URI.
+  If you love the redbean repl and want to use it as your language
+  interpreter then you can pass the `-i` flag to put redbean into
+  interpreter mode.
 
-   /usr/share/ssl/root
-           This directory contains your root certificate authorities. It is
-           needed so the Fetch() HTTPS client API can verify that a remote
-           certificate was signed by a third party. You can add your own
-           certificate files to this directory within the ZIP executable.
-           If you enable HTTPS client verification then redbean will check
-           that HTTPS clients (a) have a certificate and (b) it was signed.
+      redbean.com -i binarytrees.lua 15
 
+  When the `-i` flag is passed (for interpreter mode), redbean won't
+  start a web server and instead functions like the `lua` command. The
+  first command line argument becomes the script you want to run. If you
+  don't supply a script, then the repl without a web server is
+  displayed. This is useful for testing since redbean extensions and
+  modules for the Lua language, are still made available. You can also
+  write redbean scripts with shebang lines:
+
+      #!/usr/bin/redbean -i
+      print('hello world')
+
+  However operating systems like Linux usually require that script
+  interperters be in the local executable format. You can "assimilate"
+  and install your redbean using the following commands:
+
+      zip -d redbean.com .ape      # remove the ape header
+      ./redbean.com -h >/dev/null  # assimilate the binary
+      sudo cp redbean.com /usr/bin/redbean
+
+  By following the above steps, redbean can be installed systemwide for
+  multiple user accounts. It's also possible to chmod the binary to have
+  setuid privileges, provided it's configured to drop privileges in the
+  most appropriate manner; see the UNIX section for further details.

+LUA ENHANCEMENTS
+
+  We've made some enhancements to the Lua language that should make it
+  more comfortable for C/C++ and Python developers. Some of these
+
+    - redbean supports a printf modulus operator, like Python. For
+      example, you can say `"hello %s" % {"world"}` instead of
+      `string.format("hello %s", "world")`.
+
+    - redbean supports octal (base 8) integer literals. For example
+      `0644 == 420` is the case in redbean, whereas in upstream Lua
+      `0644 == 644` would be the case.
+
+    - redbean supports binary (base 2) integer literals. For example
+      `0b1010 == 10` is the case in redbean, whereas in upstream Lua
+      `0b1010` would result in an error.
+
+    - redbean supports the GNU syntax for the ASCII ESC character in
+      string literals. For example, `"\e"` is the same as `"\x1b"`.

 FUNCTIONS
 
-   Write(data:str)
-           Appends data to HTTP response payload buffer. This is buffered
-           independently of headers.
-
-   SetStatus(code:int[,reason:str])
-           Starts an HTTP response, specifying the parameters on its first
-           line. reason is optional since redbean can fill in the appropriate
-           text for well-known magic numbers, e.g. 200, 404, etc. This method
-           will reset the response and is therefore mutually exclusive with
-           ServeAsset and other Serve* functions. If this function isn't
-           called, then the default behavior is to send 200 OK.
-
-   SetHeader(name:str,value:str)
-           Appends HTTP header to response header buffer. name is
-           case-insensitive and restricted to non-space ASCII. value is a
-           UTF-8 string that must be encodable as ISO-8859-1. Leading and
-           trailing whitespace is trimmed automatically. Overlong characters
-           are canonicalized. C0 and C1 control codes are forbidden, with the
-           exception of tab. This function automatically calls SetStatus(200,
-           "OK") if a status has not yet been set. As SetStatus and Serve*
-           functions reset the response, SetHeader needs to be called after
-           SetStatus and Serve* functions are called. The header buffer is
-           independent of the payload buffer. Neither is written to the wire
-           until the Lua Server Page has finished executing. This function
-           disallows the setting of certain headers such as Content-Range and
-           Date, which are abstracted by the transport layer. In such cases,
-           consider calling ServeAsset.
-
-   SetCookie(name:str,value:str[,options:table])
-           Appends Set-Cookie HTTP header to the response header buffer.
-           Several Set-Cookie headers can be added to the same response.
-           __Host- and __Secure- prefixes are supported and may set or
-           overwrite some of the options (for example, specifying __Host-
-           prefix sets the Secure option to true, sets the path to "/", and
-           removes the Domain option). The following options can be used (their
-           lowercase equivalents are supported as well):
-             - Expires: sets the maximum lifetime of the cookie as an HTTP-date
-               timestamp. Can be specified as a Date in the RFC1123 (string)
-               format or as a UNIX timestamp (number of seconds).
-             - MaxAge: sets number of seconds until the cookie expires. A zero
-               or negative number will expire the cookie immediately. If both
-               Expires and MaxAge are set, MaxAge has precedence.
-             - Domain: sets the host to which the cookie will be sent.
-             - Path: sets the path that must be present in the request URL, or
-               the client will not send the Cookie header.
-             - Secure: (bool) requests the cookie to be only send to the
-               server when a request is made with the https: scheme.
-             - HttpOnly: (bool) forbids JavaScript from accessing the cookie.
-             - SameSite: (Strict, Lax, or None) controls whether a cookie is
-               sent with cross-origin requests, providing some protection
-               against cross-site request forgery attacks.
-
-   GetParam(name:str) → value:str
-           Returns first value associated with name. name is handled in a
-           case-sensitive manner. This function checks Request-URL parameters
-           first. Then it checks application/x-www-form-urlencoded from the
-           message body, if it exists, which is common for HTML forms sending
-           POST requests. If a parameter is supplied matching name that has
-           no value, e.g. foo in ?foo&bar=value, then the returned value will
-           be nil, whereas for ?foo=&bar=value it would be "". To
-           differentiate between no-equal and absent, use the HasParam
-           function. The returned value is decoded from ISO-8859-1 (only in
-           the case of Request-URL) and we assume that percent-encoded
-           characters were supplied by the client as UTF-8 sequences, which
-           are returned exactly as the client supplied them, and may
-           therefore may contain overlong sequences, control codes, NUL
-           characters, and even numbers which have been banned by the IETF.
-           It is the responsibility of the caller to impose further
-           restrictions on validity, if they're desired.
-
-   EscapeHtml(str) → str
-           Escapes HTML entities: The set of entities is &><"' which become
-           &amp;&gt;&lt;&quot;&#39;. This function is charset agnostic and
-           will not canonicalize overlong encodings. It is assumed that a
-           UTF-8 string will be supplied. See escapehtml.c.
-
-   LaunchBrowser([path:str])
-           Launches web browser on local machine with URL to this redbean
-           server. This function may be called from your /.init.lua.
-
-   CategorizeIp(ip:uint32) → str
-           Returns a string describing an IP address. This is currently Class
-           A granular. It can tell you if traffic originated from private
-           networks, ARIN, APNIC, DOD, etc.
-
-   DecodeBase64(ascii:str) → binary:str
-           Turns ASCII into binary, in a permissive way that ignores
-           characters outside the base64 alphabet, such as whitespace. See
-           decodebase64.c.
-
-   DecodeLatin1(iso-8859-1:str) → utf-8:str
-           Turns ISO-8859-1 string into UTF-8.
-
-   EncodeBase64(binary:str) → ascii:str
-           Turns binary into ASCII. This can be used to create HTML data:
-           URIs that do things like embed a PNG file in a web page. See
-           encodebase64.c.
-
-   EncodeJson(value[,options:table]) → json:str
-           Turns passed Lua value into a JSON string. Tables with non-zero
-           length (as reported by `#`) are encoded as arrays with non-array
-           elements ignored. Empty tables are encoded as empty arrays. All
-           other tables are encoded as objects with numerical keys
-           converted to strings (so `{[3]=1}` is encoded as `{"3":1}`).
-           The following options can be used:
-             - useoutput: (bool=false) encodes the result directly to the
-               output buffer and returns `nil` value. This option is
-               ignored if used outside of request handling code.
-             - numformat: (string="%.14g") sets numeric format to be used.
-             - maxdepth: (number=64) sets the max number of nested tables.
-
-   EncodeLua(value[,options:table]) → json:str
-           Turns passed Lua value into a Lua string. The following options
-           can be used:
-             - useoutput: (bool=false) encodes the result directly to the
-               output buffer and returns `nil` value. This option is
-               ignored if used outside of request handling code.
-             - numformat: (string="%.14g") sets numeric format to be used.
-             - maxdepth: (number=64) sets the max number of nested tables.
-
-   EncodeLatin1(utf-8:str[,flags:int]) → iso-8859-1:str
-           Turns UTF-8 into ISO-8859-1 string.
-
-   EscapeFragment(str) → str
-           Escapes URL #fragment. The allowed characters are
-           -/?.~_@:!$&'()*+,;=0-9A-Za-z and everything else gets %XX encoded.
-           Please note that '& can still break HTML and that '() can still
-           break CSS URLs. This function is charset agnostic and will not
-           canonicalize overlong encodings. It is assumed that a UTF-8 string
-           will be supplied. See kescapefragment.c.
-
-   EscapeHost(str) → str
-           Escapes URL host. See kescapeauthority.c
-
-   EscapeLiteral(str) → str
-           Escapes JavaScript or JSON string literal content. The caller is
-           responsible for adding the surrounding quotation marks. This
-           implementation \uxxxx sequences for all non-ASCII sequences. HTML
-           entities are also encoded, so the output doesn't need EscapeHtml.
-           This function assumes UTF-8 input. Overlong encodings are
-           canonicalized. Invalid input sequences are assumed to be
-           ISO-8859-1. The output is UTF-16 since that's what JavaScript
-           uses. For example, some individual codepoints such as emoji
-           characters will encode as multiple \uxxxx sequences. Ints that are
-           impossible to encode as UTF-16 are substituted with the \xFFFD
-           replacement character. See escapejsstringliteral.c.
-
-   EscapeParam(str) → str
-           Escapes URL parameter name or value. The allowed characters are
-           -.*_0-9A-Za-z and everything else gets %XX encoded. This function
-           is charset agnostic and will not canonicalize overlong encodings.
-           It is assumed that a UTF-8 string will be supplied. See
-           kescapeparam.c.
-
-   EscapePass(str) → str
-           Escapes URL password. See kescapeauthority.c.
-
-   EscapePath(str) → str
-           Escapes URL path. This is the same as EscapeSegment except slash
-           is allowed. The allowed characters are -.~_@:!$&'()*+,;=0-9A-Za-z/
-           and everything else gets %XX encoded. Please note that '& can
-           still break HTML, so the output may need EscapeHtml too. Also note
-           that '() can still break CSS URLs. This function is charset
-           agnostic and will not canonicalize overlong encodings. It is
-           assumed that a UTF-8 string will be supplied. See kescapepath.c.
-
-   EscapeSegment(str) → str
-           Escapes URL path segment. This is the same as EscapePath except
-           slash isn't allowed. The allowed characters are
-           -.~_@:!$&'()*+,;=0-9A-Za-z and everything else gets %XX encoded.
-           Please note that '& can still break HTML, so the output may need
-           EscapeHtml too. Also note that '() can still break CSS URLs. This
-           function is charset agnostic and will not canonicalize overlong
-           encodings. It is assumed that a UTF-8 string will be supplied. See
-           kescapesegment.c.
-
-   EscapeUser(str) → str
-           Escapes URL username. See kescapeauthority.c.
-
-   Fetch(url:str[,body:str|{method=value:str,body=value:str,...}])
-       → status:int,{header:str=value:str,...},body:str
-           Sends an HTTP/HTTPS request to the specified URL. If only the URL is
-           provided, then a GET request is sent. If both URL and body parameters
-           are specified, then a POST request is sent. If any other method needs
-           to be specified (for example, PUT or DELETE), then passing a table as
-           the second value allows setting method and body values as well other
-           options:
-             - method (default = "GET"): sets the method to be used for the
-               request. The specified method is converted to uppercase.
-             - body (default = ""): sets the body value to be sent.
-             - followredirect (default = true): forces temporary and permanent
-               redirects to be followed. This behavior can be disabled by
-               passing `false`.
-             - maxredirects (default = 5): sets the number of allowed redirects
-               to minimize looping due to misconfigured servers. When the number
-               is exceeded, the result of the last redirect is returned.
-           When the redirect is being followed, the same method and body values
-           are being sent in all cases except when 303 status is returned. In
-           that case the method is set to GET and the body is removed before the
-           redirect is followed. Note that if these (method/body) values are
-           provided as table fields, they will be modified in place.
-
-   FormatHttpDateTime(seconds:int) → rfc1123:str
-           Converts UNIX timestamp to an RFC1123 string that looks like this:
-           Mon, 29 Mar 2021 15:37:13 GMT. See formathttpdatetime.c.
-
-   FormatIp(uint32) → str
-           Turns integer like 0x01020304 into a string like 1.2.3.4. See also
-           ParseIp for the inverse operation.
-
-   GetAssetComment(path:str) → str
-           Returns comment text associated with asset in the ZIP central
-           directory. Also available as GetComment (deprecated).
-
-   GetAssetMode(path:str) → int
-           Returns UNIX-style octal mode for ZIP asset (or local file if the
-           -D flag is used)
-
-   GetAssetSize(path:str) → int
-           Returns byte size of uncompressed contents of ZIP asset (or local
-           file if the -D flag is used)
-
-   GetBody() → str
-           Returns the request message body if present or an empty string.
-           Also available as GetPayload (deprecated).
-
-   GetCookie(name:str) → str
-           Returns cookie value.
-
-   GetCryptoHash(name:str,payload:str[,key:str]) → str
-           Returns value of the specified cryptographic hash function. If the
-           key is provided, then HMAC value of the same function is returned.
-           The name can be one of the following strings: MD5, SHA1, SHA224,
-           SHA256, SHA384, SHA512, and BLAKE2B256.
-
-   GetRemoteAddr() → ip:uint32,port:uint16
-           Returns client ip4 address and port, e.g. 0x01020304,31337 would
-           represent 1.2.3.4:31337. This is the same as GetClientAddr except
-           it will use the ip:port from the X-Forwarded-For header, only if
-           IsPrivateIp or IsLoopbackIp return true.
-
-   GetClientAddr() → ip:uint32,port:uint16
-           Returns client socket ip4 address and port, e.g. 0x01020304,31337
-           would represent 1.2.3.4:31337. Please consider using GetRemoteAddr
-           instead, since the latter takes into consideration reverse proxy
-           scenarios.
-
-   GetServerAddr() → ip:uint32,port:uint16
-           Returns address to which listening server socket is bound, e.g.
-           0x01020304,8080 would represent 1.2.3.4:8080. If -p 0 was supplied
-           as the listening port, then the port in this string will be
-           whatever number the operating system assigned.
-
-   GetDate() → seconds:int
-           Returns date associated with request that's used to generate the
-           Date header, which is now, give or take a second. The returned
-           value is a UNIX timestamp.
-
-   GetHeader(name:str) → value:str
-           Returns HTTP header. name is case-insensitive. The header value is
-           returned as a canonical UTF-8 string, with leading and trailing
-           whitespace trimmed, which was decoded from ISO-8859-1, which is
-           guaranteed to not have C0/C1 control sequences, with the exception
-           of the tab character. Leading and trailing whitespace is
-           automatically removed. In the event that the client suplies raw
-           UTF-8 in the HTTP message headers, the original UTF-8 sequence can
-           be losslessly restored by counter-intuitively recoding the
-           returned string back to Latin1. If the requested header is defined
-           by the RFCs as storing comma-separated values (e.g. Allow,
-           Accept-Encoding) and the field name occurs multiple times in the
-           message, then this function will fold those multiple entries into
-           a single string.
-
-   GetHeaders() → {name:str=value:str,...}
-           Returns HTTP headers as dictionary mapping header key strings to
-           their UTF-8 decoded values. The ordering of headers from the
-           request message is not preserved. Whether or not the same key can
-           repeat depends on whether or not it's a standard header, and if
-           so, if it's one of the ones that the RFCs define as repeatable.
-           See khttprepeatable.c. Those headers will not be folded. Standard
-           headers which aren't on that list, will be overwritten with the
-           last-occurring one during parsing. Extended headers are always
-           passed through exactly as they're received. Please consider using
-           GetHeader API if possible since it does a better job abstracting
-           these issues.
-
-   GetLogLevel() → int
-           Returns logger verbosity level. Likely return values are kLogDebug
-           > kLogVerbose > kLogInfo > kLogWarn > kLogError > kLogFatal.
-
-   GetHost() → str
-           Returns host associated with request. This will be the Host
-           header, if it's supplied. Otherwise it's the bind address.
-
-   GetHostOs() → str
-           Returns string that describes the host OS.
-
-   GetMonospaceWidth(str|char) → int
-           Returns monospace display width of string. This is useful for
-           fixed-width formatting. For example, CJK characters typically take
-           up two cells. This function takes into consideration combining
-           characters, which are discounted, as well as control codes and
-           ANSI escape sequences.
-
-   GetMethod() → str
-           Returns HTTP method. Normally this will be GET, HEAD, or POST in
-           which case redbean normalizes this value to its uppercase form.
-           Anything else that the RFC classifies as a "token" string is
-           accepted too, which might contain characters like &".
-
-   GetParams() → {{name:str[,value:str]},...}
-           Returns name=value parameters from Request-URL and
-           application/x-www-form-urlencoded message body in the order they
-           were received. This may contain duplicates. The inner array will
-           have either one or two items, depending on whether or not the
-           equals sign was used.
-
-   GetPath() → str
-           Returns the Request-URL path. This is guaranteed to begin with
-           "/". It is further guaranteed that no "//" or "/." exists in the
-           path. The returned value is returned as a UTF-8 string which was
-           decoded from ISO-8859-1. We assume that percent-encoded characters
-           were supplied by the client as UTF-8 sequences, which are returned
-           exactly as the client supplied them, and may therefore may contain
-           overlong sequences, control codes, NUL characters, and even
-           numbers which have been banned by the IETF. redbean takes those
-           things into consideration when performing path safety checks. It
-           is the responsibility of the caller to impose further restrictions
-           on validity, if they're desired.
-
-   GetEffectivePath() → str
-           Returns path as it was resolved by the routing algorithms, which
-           might contain the virtual host prepended if used.
-
-   GetScheme() → str
-           Returns scheme from Request-URL, if any.
-
-   GetStatus() → int
-           Returns current status (as set by an earlier SetStatus call) or
-           `nil` if the status hasn't been set yet.
-
-   GetTime() → seconds:number
-           Returns current time as a UNIX timestamp with 0.0001s precision.
-
-   GetUrl() → str
-           Returns the effective Request-URL as an ASCII string, where
-           illegal characters or UTF-8 is guaranteed to be percent encoded,
-           and has been normalized to include either the Host or
-           X-Forwarded-Host headers, if they exist, and possibly a scheme too
-           if redbean is being used as an HTTP proxy server. In the future
-           this API might change to return an object instead.
-
-   GetHttpVersion() → int
-           Returns the request HTTP protocol version, which can be 9 for
-           HTTP/0.9, 10 for HTTP/1.0, or 11 for HTTP/1.1. Also available
-           as GetVersion (deprecated).
-
-   GetRandomBytes([length:int]) → str
-           Returns string with the specified number of random bytes (1..256).
-           If no length is specified, then a string of length 16 is returned.
-
-   GetRedbeanVersion() → int
-           Returns the Redbean version in the format 0xMMmmpp, with major (MM),
-           minor (mm), and patch (pp) versions encoded. The version value 1.4
-           would be represented as 0x010400.
-
-   GetZipPaths([prefix:str]) → {path:str,...}
-           Returns paths of all assets in the zip central directory, prefixed
-           by a slash. If prefix parameter is provided, then only paths that
-           start with the prefix (case sensitive) are returned.
-
-   HasParam(name:str) → bool
-           Returns true if parameter with name was supplied in either the
-           Request-URL or an application/x-www-form-urlencoded message body.
-
-   HidePath(prefix:str)
-           Programs redbean / listing page to not display any paths beginning
-           with prefix. This function should only be called from /.init.lua.
-
-   IsPublicIp(uint32) → bool
-           Returns true if IP address is not a private network (10.0.0.0/8,
-           172.16.0.0/12, 192.168.0.0/16) and is not localhost (127.0.0.0/8).
-           Note: we intentionally regard TEST-NET IPs as public.
-
-   IsPrivateIp(uint32) → bool
-           Returns true if IP address is part of a private network
-           (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).
-
-   IsLoopbackClient() → bool
-           Returns true if the client IP address (returned by GetRemoteAddr)
-           is part of the localhost network (127.0.0.0/8).
-
-   IsLoopbackIp(uint32) → bool
-           Returns true if IP address is part of the localhost network
-           (127.0.0.0/8).
-
-   IsCompressed(path:str) → bool
-           Returns true if ZIP artifact at path is stored on disk using
-           DEFLATE compression.
-
-   IndentLines(str[,int]) → str
-           Adds spaces to beginnings of multiline string. If the int
-           parameter is not supplied then 1 space will be added.
-
-   LoadAsset(path:str) → str
-           Returns contents of file as string. The asset may be sourced from
-           either the zip (decompressed) or the local filesystem if the -D
-           flag was used. If slurping large file into memory is a concern,
-           then consider using ServeAsset which can serve directly off disk.
-
-   StoreAsset(path:str,data:str,mode:int)
-           Stores asset to executable's ZIP central directory. This currently
-           happens in an append-only fashion and is still largely in the
-           proof-of-concept stages. Currently only supported on Linux, XNU,
-           and FreeBSD.
-
-   Log(level:int,message:str)
-           Emits message string to log, if level is less than or equal to
-           GetLogLevel. If redbean is running in interactive mode, then this
-           will log to the console. If redbean is running as a daemon or the
-           -L LOGFILE flag is passed, then this will log to the file.
-           Reasonable values for level are kLogDebug > kLogVerbose > kLogInfo
-           > kLogWarn > kLogError > kLogFatal. The logger emits timestamps in
-           the local timezone with microsecond precision. If log entries are
-           emitted more frequently than once per second, then the log entry
-           will display a delta timestamp, showing how much time has elapsed
-           since the previous log entry. This behavior is useful for quickly
-           measuring how long various portions of your code take to execute.
-
-   ParseHttpDateTime(rfc1123:str) → seconds:int
-           Converts RFC1123 string that looks like this: Mon, 29 Mar 2021
-           15:37:13 GMT to a UNIX timestamp. See parsehttpdatetime.c.
-
-   ParseUrl(str) → URL
-           Parses URL, returning object having the following fields: scheme,
-           user, pass, host, port, path, params, fragment. This parser is
-           charset agnostic. Percent encoded bytes are decoded for all
-           fields. Returned values might contain things like NUL characters,
-           spaces, control codes, and non-canonical encodings. Absent can be
-           discerned from empty by checking if the pointer is set. There's no
-           failure condition for this routine. This is a permissive parser.
-           This doesn't normalize path segments like `.` or `..` so use
-           IsAcceptablePath() to check for those. No restrictions are imposed
-           beyond that which is strictly necessary for parsing. All the data
-           that is provided will be consumed to the one of the fields. Strict
-           conformance is enforced on some fields more than others, like
-           scheme, since it's the most non-deterministically defined field of
-           them all. Please note this is a URL parser, not a URI parser.
-           Which means we support everything everything the URI spec says we
-           should do except for the things we won't do, like tokenizing path
-           segments into an array and then nesting another array beneath each
-           of those for storing semicolon parameters. So this parser won't
-           make SIP easy. What it can do is parse HTTP URLs and most URIs
-           like data:opaque, better in fact than most things which claim to
-           be URI parsers.
-
-   EncodeUrl(URL) → str
-           This function is the inverse of ParseUrl. The output will always
-           be correctly formatted. The exception is if illegal characters are
-           supplied in the scheme field, since there's no way of escaping
-           those. Opaque parts are escaped as though they were paths, since
-           many URI parsers won't understand things like an unescaped
-           question mark in path.
-
-   ParseIp(str) → int
-           Converts IPv4 address string to integer, e.g. "1.2.3.4" →
-           0x01020304, or returns -1 for invalid inputs. See also FormatIp
-           for the inverse operation.
-
-   ProgramAddr(str)
-           Configures the address on which to listen. Can be used multiple
-           times to set more than one address.
-
-   ProgramBrand(str)
-           Changes HTTP Server header, as well as the <h1> title on the /
-           listing page. The brand string needs to be a UTF-8 value that's
-           encodable as ISO-8859-1. If the brand is changed to something
-           other than redbean, then the promotional links will be removed
-           from the listing page too. This function should only be called
-           from /.init.lua.
-
-   ProgramCache(seconds:int)
-           Configures Cache-Control and Expires header generation for static
-           asset serving. A negative value will disable the headers. Zero
-           means don't cache. Greater than zero asks public proxies and
-           browsers to cache for a given number of seconds. This should only
-           be called from /.init.lua.
-
-   ProgramCertificate(pem:str)
-           Same as the -C flag if called from .init.lua, e.g.
-           ProgramCertificate(LoadAsset("/.sign.crt")) for zip loading or
-           ProgramCertificate(Slurp("/etc/letsencrypt.lol/fullchain.pem")) for
-           local file system only.
-
-   ProgramHeader(name:str,value:str)
-           Appends HTTP header to the header buffer for all responses (whereas
-           SetHeader only appends a header to the current response buffer).
-           name is case-insensitive and restricted to non-space ASCII. value
-           is a UTF-8 string that must be encodable as ISO-8859-1. Leading and
-           trailing whitespace is trimmed automatically. Overlong characters
-           are canonicalized. C0 and C1 control codes are forbidden, with the
-           exception of tab. The header buffer is independent of the payload
-           buffer. This function disallows the setting of certain headers such
-           as Content-Range and Date, which are abstracted by the transport
-           layer.
-
-   ProgramPort(uint16)
-           Hard-codes the port number on which to listen, which can be any
-           number in the range 1..65535, or alternatively 0 to ask the
-           operating system to choose a port, which may be revealed later on
-           by GetServerAddr or the -z flag to stdout.
-
-   ProgramPrivateKey(pem:str)
-           Same as the -K flag if called from .init.lua, e.g.
-           ProgramPrivateKey(LoadAsset("/.sign.key")) for zip loading or
-           ProgramPrivateKey(Slurp("/etc/letsencrypt/fullchain.pem")) for
-           local file system only.
-
-   ProgramRedirect(code:int,src:str,location:str)
-           Configures fallback routing for paths which would otherwise return
-           404 Not Found. If code is 0 then the path is rewritten internally
-           as an accelerated redirect. If code is 301, 302, 307, or 308 then
-           a redirect response will be sent to the client. This should only
-           be called from /.init.lua.
-
-   ProgramSslTicketLifetime(seconds:int)
-           Defaults to 86400 (24 hours). This may be set to ≤0 to disable
-           SSL tickets. It's a good idea to use these since it increases
-           handshake performance 10x and eliminates a network round trip.
-
-   EvadeDragnetSurveillance(bool)
-           If this option is programmed then redbean will not transmit a
-           Server Name Indicator (SNI) when performing Fetch() requests.
-
-   ProgramSslPresharedKey(key:str,identity:str)
-           This function can be used to enable the PSK ciphersuites
-           which simplify SSL and enhance its performance in controlled
-           environments. `key` may contain 1..32 bytes of random binary
-           data and identity is usually a short plaintext string. The
-           first time this function is called, the preshared key will
-           be added to both the client and the server SSL configs. If
-           it's called multiple times, then the remaining keys will be
-           added to the server, which is useful if you want to assign
-           separate keys to each client, each of which needs a separate
-           identity too. If this function is called multiple times with
-           the same identity string, then the latter call will overwrite
-           the prior. If a preshared key is supplied and no certificates
-           or key-signing-keys are programmed, then redbean won't bother
-           auto-generating any serving certificates and will instead use
-           only PSK ciphersuites.
-
-   ProgramSslCiphersuite(name:str)
-           See https://redbean.dev/ for further details.
-
-   IsDaemon() → bool
-           Returns true if -d flag was passed to redbean.
-
-   ProgramUid(int)
-           Same as the -U flag if called from .init.lua for setuid()
-
-   ProgramGid(int)
-           Same as the -G flag if called from .init.lua for setgid()
-
-   ProgramDirectory(str)
-           Same as the -D flag if called from .init.lua for overlaying local
-           file system directories. This may be called multiple times. The
-           first directory programmed is preferred. These currently do not
-           show up in the index page listing.
-
-   ProgramLogMessages(bool)
-           Same as the -m flag if called from .init.lua for logging message
-           headers only.
-
-   ProgramLogBodies(bool)
-           Same as the -b flag if called from .init.lua for logging message
-           bodies as part of POST / PUT / etc. requests.
-
-   ProgramLogPath(str)
-           Same as the -L flag if called from .init.lua for setting the log
-           file path on the local file system. It's created if it doesn't
-           exist. This is called before de-escalating the uesr / group id.
-           The file is opened in append only mode. If the disk runs out of
-           space then redbean will truncate the log file if has access to
-           change the log file after daemonizing.
-
-   ProgramPidPath(str)
-           Same as the -P flag if called from .init.lua for setting the pid
-           file path on the local file system. It's useful for reloading
-           daemonized redbean using `kill -HUP $(cat /var/run/redbean.pid)`
-           or terminating redbean with `kill $(cat /var/run/redbean.pid)`
-           which will gracefully terminate all clients. Sending the TERM
-           signal twice will cause a forceful shutdown, which might make
-           someone with a slow internet connection who's downloading big
-           files unhappy.
-
-   Slurp(filename:str) → str
-           Reads file data from local file system.
-
-   Sleep(seconds:number)
-           Sleeps the specified number of seconds (can be fractional). The
-           smallest interval is a microsecond.
-
-   Route([host:str,[path:str]])
-           Instructs redbean to follow the normal HTTP serving path. This
-           function is useful when writing an OnHttpRequest handler, since
-           that overrides the serving path entirely. So if the handler
-           decides it doesn't want to do anything, it can simply call this
-           function, to hand over control back to the redbean core. By
-           default, the host and path arguments are supplied from the
-           resolved GetUrl value. This handler always resolves, since it will
-           generate a 404 Not Found response if redbean couldn't find an
-           appropriate endpoint.
-
-   RouteHost([host:str,[path:str]]) → bool
-           This is the same as Route, except it only implements the subset of
-           request routing needed for serving virtual-hosted assets, where
-           redbean tries to prefix the path with the hostname when looking up
-           a file. This function returns true if the request was resolved. If
-           it was resolved, then your OnHttpRequest request handler can still
-           set additional headers.
-
-   RoutePath([path:str]) → bool
-           This is the same as Route, except it only implements the subset of
-           request routing needed for serving assets. This function returns
-           true if the request was resolved. If it was resolved, then your
-           OnHttpRequest request handler can still set additional headers.
-
-   ServeAsset(path:str)
-           Instructs redbean to serve static asset at path. This function
-           causes what would normally happen outside a dynamic handler to
-           happen. The asset can be sourced from either the zip or local
-           filesystem if -D is used. This function is mutually exclusive with
-           SetStatus and other Serve* functions.
-
-   ServeError(code:int[,reason:str])
-           Instructs redbean to serve a boilerplate error page. This takes
-           care of logging the error, setting the reason phrase, and adding a
-           payload. This function is mutually exclusive with SetStatus and
-           other Serve* functions.
-
-   ServeRedirect(code:int,location:str)
-           Instructs redbean to return the specified redirect code along with
-           the Location header set. This function is mutually exclusive with
-           SetStatus and other Serve* functions.
-
-   SetLogLevel(level:int)
-           Sets logger verbosity. Reasonable values for level are kLogDebug >
-           kLogVerbose > kLogInfo > kLogWarn > kLogError > kLogFatal. This is
-           reset at the end of the http request, so it can be used to disable
-           access log and message logging.
-
-   VisualizeControlCodes(str) → str
-           Replaces C0 control codes with their UNICODE pictures
-           representation. This function also canonicalizes overlong
-           encodings. C1 control codes are replaced with a JavaScript-like
-           escape sequence.
-
-   Underlong(str) → str
-           Canonicalizes overlong encodings.
-
-   Crc32(initial:int,data:str) → int
-           Computes 32-bit CRC-32 used by zip/zlib/gzip/etc.
-
-   Crc32c(initial:int,data:str) → int
-           Computes 32-bit Castagnoli Cyclic Redundancy Check.
-
-   Md5(str) → str
-           Computes MD5 checksum, returning 16 bytes of binary.
-
-   Sha1(str) → str
-           Computes SHA1 checksum, returning 20 bytes of binary.
-
-   Sha224(str) → str
-           Computes SHA224 checksum, returning 28 bytes of binary.
-
-   Sha256(str) → str
-           Computes SHA256 checksum, returning 32 bytes of binary.
-
-   Sha384(str) → str
-           Computes SHA384 checksum, returning 48 bytes of binary.
-
-   Sha512(str) → str
-           Computes SHA512 checksum, returning 64 bytes of binary.
-
-   Bsf(x:int) → int
-           Returns position of first bit set. Passing 0 will raise an error.
-           Same as the Intel x86 instruction BSF.
-
-   Bsr(x:int) → int
-           Returns binary logarithm of 𝑥. Passing 0 will raise an error. Same
-           as the Intel x86 instruction BSR.
-
-   Popcnt(x:int) → int
-           Returns number of bits set in integer.
-
-LSQLITE3 MODULE
-
-   Please refer to the LuaSQLite3 Documentation.
-
-   For example, you could put the following in your /.init.lua file:
-
-     sqlite3 = require "lsqlite3"
-     db = sqlite3.open_memory()
-     db:exec[[
-       CREATE TABLE test (
-         id INTEGER PRIMARY KEY,
-         content TEXT
-       );
-       INSERT INTO test (content) VALUES ('Hello World');
-       INSERT INTO test (content) VALUES ('Hello Lua');
-       INSERT INTO test (content) VALUES ('Hello Sqlite3');
-     ]]
-
-   Then, your Lua server pages or OnHttpRequest handler may perform SQL
-   queries by accessing the db global. The performance is good too, at about
-   400k qps.
-
-     for row in db:nrows("SELECT * FROM test") do
-        Write(row.id.." "..row.content.."<br>")
-     end
-
-   redbean supports a subset of what's defined in the upstream LuaSQLite3
-   project. Most of the unsupported APIs relate to pointers and database
-   notification hooks.
-
-   redbean also currently disables SQLite features which don't make sense for
-   production serving, such as ALTER, VACUUM, ANALYZE, etc. For that reason
-   we provide an APE build of the SQLite shell which you can use to
-   administrate your redbean database. See the sqlite3.com download above.
-
-RE MODULE
-
-   This module exposes an API for POSIX regular expressions which enable you
-   to validate input, search for substrings, extract pieces of strings, etc.
-   Here's a usage example:
-
-     # Example IPv4 Address Regular Expression (see also ParseIP)
-     p = re.compile([[^([0-9]{1,3})\.([0-9]{1,3})\.([0-9]{1,3})\.([0-9]{1,3})$]])
-     m,a,b,c,d = p:search(𝑠)
-     if m then
-       print("ok", tonumber(a), tonumber(b), tonumber(c), tonumber(d))
-     else
-       print("not ok")
-     end
-
-   re.search(regex:str,text:str[,flags:int]) → [match[,group_1,...]]
-           Shortcut for re.compile plus regex_t*:search.
-
-   re.compile(regex:str[,flags:int]) → regex_t*
-           Compiles regular expression, using the POSIX extended syntax. This
-           has an O(2^𝑛) cost, so it's a good idea to do this from your
-           /.init.lua file. Flags may contain re.BASIC, re.ICASE, re.NOSUB,
-           and/or re.NEWLINE. See also regcomp() from libc.
-
-   regex_t*:search(text:str[,flags:int]) → [match[,group_1,...]]
-           Executes regular expression. This has an O(𝑛) cost. This returns
-           nothing (nil) if the pattern doesn't match anything. Otherwise it
-           pushes the matched substring and any parenthesis-captured values
-           too. Flags may contain re.NOTBOL or re.NOTEOL to indicate whether
-           or not text should be considered at the start and/or end of a
-           line.
-
-   re.BASIC
-           Use this flag if you prefer the default POSIX regex syntax. We use
-           extended regex notation by default. For example, an extended
-           regular expression for matching an IP address might look like
-           ([0-9]*)\.([0-9]*)\.([0-9]*)\.([0-9]*) whereas with basic syntax
-           it would look like \([0-9]*\)\.\([0-9]*\)\.\([0-9]*\)\.\([0-9]*\).
-           This flag may only be used with re.compile and re.search.
-
-   re.ICASE
-           Use this flag to make your pattern case ASCII case-insensitive.
-           This means [a-z] will mean the same thing as [A-Za-z]. This flag
-           may only be used with re.compile and re.search.
-
-   re.NEWLINE
-           Use this flag to change the handling of NEWLINE (\x0a) characters.
-           When this flag is set, (1) a NEWLINE shall not be matched by a "."
-           or any form of a non-matching list, (2) a "^" shall match the
-           zero-length string immediately after a NEWLINE (regardless of
-           re.NOTBOL), and (3) a "$" shall match the zero-length string
-           immediately before a NEWLINE (regardless of re.NOTEOL).
-
-   re.NOSUB
-           Causes re.search to only report success and failure. This is
-           reported via the API by returning empty string for success. This
-           flag may only be used with re.compile and re.search.
-
-   re.NOTBOL
-           The first character of the string pointed to by string is not the
-           beginning of the line. This flag may only be used with re.search
-           and regex_t*:search.
-
-   re.NOTEOL
-           The last character of the string pointed to by string is not the
-           end of the line. This flag may only be used with re.search and
-           regex_t*:search.
+  Write(data:str)
+          Appends data to HTTP response payload buffer. This is buffered
+          independently of headers.
+
+  SetStatus(code:int[,reason:str])
+          Starts an HTTP response, specifying the parameters on its first
+          line. reason is optional since redbean can fill in the appropriate
+          text for well-known magic numbers, e.g. 200, 404, etc. This method
+          will reset the response and is therefore mutually exclusive with
+          ServeAsset and other Serve* functions. If this function isn't
+          called, then the default behavior is to send 200 OK.
+
+  SetHeader(name:str,value:str)
+          Appends HTTP header to response header buffer. name is
+          case-insensitive and restricted to non-space ASCII. value is a
+          UTF-8 string that must be encodable as ISO-8859-1. Leading and
+          trailing whitespace is trimmed automatically. Overlong characters
+          are canonicalized. C0 and C1 control codes are forbidden, with the
+          exception of tab. This function automatically calls SetStatus(200,
+          "OK") if a status has not yet been set. As SetStatus and Serve*
+          functions reset the response, SetHeader needs to be called after
+          SetStatus and Serve* functions are called. The header buffer is
+          independent of the payload buffer. Neither is written to the wire
+          until the Lua Server Page has finished executing. This function
+          disallows the setting of certain headers such as Content-Range and
+          Date, which are abstracted by the transport layer. In such cases,
+          consider calling ServeAsset.
+
+  SetCookie(name:str,value:str[,options:table])
+          Appends Set-Cookie HTTP header to the response header buffer.
+          Several Set-Cookie headers can be added to the same response.
+          __Host- and __Secure- prefixes are supported and may set or
+          overwrite some of the options (for example, specifying __Host-
+          prefix sets the Secure option to true, sets the path to "/", and
+          removes the Domain option). The following options can be used (their
+          lowercase equivalents are supported as well):
+            - Expires: sets the maximum lifetime of the cookie as an HTTP-date
+              timestamp. Can be specified as a Date in the RFC1123 (string)
+              format or as a UNIX timestamp (number of seconds).
+            - MaxAge: sets number of seconds until the cookie expires. A zero
+              or negative number will expire the cookie immediately. If both
+              Expires and MaxAge are set, MaxAge has precedence.
+            - Domain: sets the host to which the cookie will be sent.
+            - Path: sets the path that must be present in the request URL, or
+              the client will not send the Cookie header.
+            - Secure: (bool) requests the cookie to be only send to the
+              server when a request is made with the https: scheme.
+            - HttpOnly: (bool) forbids JavaScript from accessing the cookie.
+            - SameSite: (Strict, Lax, or None) controls whether a cookie is
+              sent with cross-origin requests, providing some protection
+              against cross-site request forgery attacks.
+
+  GetParam(name:str) → value:str
+          Returns first value associated with name. name is handled in a
+          case-sensitive manner. This function checks Request-URL parameters
+          first. Then it checks application/x-www-form-urlencoded from the
+          message body, if it exists, which is common for HTML forms sending
+          POST requests. If a parameter is supplied matching name that has
+          no value, e.g. foo in ?foo&bar=value, then the returned value will
+          be nil, whereas for ?foo=&bar=value it would be "". To
+          differentiate between no-equal and absent, use the HasParam
+          function. The returned value is decoded from ISO-8859-1 (only in
+          the case of Request-URL) and we assume that percent-encoded
+          characters were supplied by the client as UTF-8 sequences, which
+          are returned exactly as the client supplied them, and may
+          therefore may contain overlong sequences, control codes, NUL
+          characters, and even numbers which have been banned by the IETF.
+          It is the responsibility of the caller to impose further
+          restrictions on validity, if they're desired.
+
+  EscapeHtml(str) → str
+          Escapes HTML entities: The set of entities is &><"' which become
+          &amp;&gt;&lt;&quot;&#39;. This function is charset agnostic and
+          will not canonicalize overlong encodings. It is assumed that a
+          UTF-8 string will be supplied. See escapehtml.c.
+
+  LaunchBrowser([path:str])
+          Launches web browser on local machine with URL to this redbean
+          server. This function may be called from your /.init.lua.
+
+  CategorizeIp(ip:uint32) → str
+          Returns a string describing an IP address. This is currently Class
+          A granular. It can tell you if traffic originated from private
+          networks, ARIN, APNIC, DOD, etc.
+
+  DecodeBase64(ascii:str) → binary:str
+          Turns ASCII into binary, in a permissive way that ignores
+          characters outside the base64 alphabet, such as whitespace. See
+          decodebase64.c.
+
+  DecodeLatin1(iso-8859-1:str) → utf-8:str
+          Turns ISO-8859-1 string into UTF-8.
+
+  EncodeBase64(binary:str) → ascii:str
+          Turns binary into ASCII. This can be used to create HTML data:
+          URIs that do things like embed a PNG file in a web page. See
+          encodebase64.c.
+
+  EncodeJson(value[,options:table]) → json:str
+          Turns passed Lua value into a JSON string. Tables with non-zero
+          length (as reported by `#`) are encoded as arrays with non-array
+          elements ignored. Empty tables are encoded as empty arrays. All
+          other tables are encoded as objects with numerical keys
+          converted to strings (so `{[3]=1}` is encoded as `{"3":1}`).
+          The following options can be used:
+            - useoutput: (bool=false) encodes the result directly to the
+              output buffer and returns `nil` value. This option is
+              ignored if used outside of request handling code.
+            - numformat: sets numeric format to be used, which can be 'g',
+              'f', or 'a' [experimental api]
+
+  EncodeLua(value[,options:table]) → json:str
+          Turns passed Lua value into a Lua string. The following options
+          can be used:
+            - useoutput: (bool=false) encodes the result directly to the
+              output buffer and returns `nil` value. This option is
+              ignored if used outside of request handling code.
+
+  EncodeLatin1(utf-8:str[,flags:int]) → iso-8859-1:str
+          Turns UTF-8 into ISO-8859-1 string.
+
+  EscapeFragment(str) → str
+          Escapes URL #fragment. The allowed characters are
+          -/?.~_@:!$&'()*+,;=0-9A-Za-z and everything else gets %XX encoded.
+          Please note that '& can still break HTML and that '() can still
+          break CSS URLs. This function is charset agnostic and will not
+          canonicalize overlong encodings. It is assumed that a UTF-8 string
+          will be supplied. See kescapefragment.c.
+
+  EscapeHost(str) → str
+          Escapes URL host. See kescapeauthority.c
+
+  EscapeLiteral(str) → str
+          Escapes JavaScript or JSON string literal content. The caller is
+          responsible for adding the surrounding quotation marks. This
+          implementation \uxxxx sequences for all non-ASCII sequences. HTML
+          entities are also encoded, so the output doesn't need EscapeHtml.
+          This function assumes UTF-8 input. Overlong encodings are
+          canonicalized. Invalid input sequences are assumed to be
+          ISO-8859-1. The output is UTF-16 since that's what JavaScript
+          uses. For example, some individual codepoints such as emoji
+          characters will encode as multiple \uxxxx sequences. Ints that are
+          impossible to encode as UTF-16 are substituted with the \xFFFD
+          replacement character. See escapejsstringliteral.c.
+
+  EscapeParam(str) → str
+          Escapes URL parameter name or value. The allowed characters are
+          -.*_0-9A-Za-z and everything else gets %XX encoded. This function
+          is charset agnostic and will not canonicalize overlong encodings.
+          It is assumed that a UTF-8 string will be supplied. See
+          kescapeparam.c.
+
+  EscapePass(str) → str
+          Escapes URL password. See kescapeauthority.c.
+
+  EscapePath(str) → str
+          Escapes URL path. This is the same as EscapeSegment except slash
+          is allowed. The allowed characters are -.~_@:!$&'()*+,;=0-9A-Za-z/
+          and everything else gets %XX encoded. Please note that '& can
+          still break HTML, so the output may need EscapeHtml too. Also note
+          that '() can still break CSS URLs. This function is charset
+          agnostic and will not canonicalize overlong encodings. It is
+          assumed that a UTF-8 string will be supplied. See kescapepath.c.
+
+  EscapeSegment(str) → str
+          Escapes URL path segment. This is the same as EscapePath except
+          slash isn't allowed. The allowed characters are
+          -.~_@:!$&'()*+,;=0-9A-Za-z and everything else gets %XX encoded.
+          Please note that '& can still break HTML, so the output may need
+          EscapeHtml too. Also note that '() can still break CSS URLs. This
+          function is charset agnostic and will not canonicalize overlong
+          encodings. It is assumed that a UTF-8 string will be supplied. See
+          kescapesegment.c.
+
+  EscapeUser(str) → str
+          Escapes URL username. See kescapeauthority.c.
+
+  Fetch(url:str[,body:str|{method=value:str,body=value:str,...}])
+      → status:int,{header:str=value:str,...},body:str
+          Sends an HTTP/HTTPS request to the specified URL. If only the URL is
+          provided, then a GET request is sent. If both URL and body parameters
+          are specified, then a POST request is sent. If any other method needs
+          to be specified (for example, PUT or DELETE), then passing a table as
+          the second value allows setting method and body values as well other
+          options:
+            - method (default = "GET"): sets the method to be used for the
+              request. The specified method is converted to uppercase.
+            - body (default = ""): sets the body value to be sent.
+            - followredirect (default = true): forces temporary and permanent
+              redirects to be followed. This behavior can be disabled by
+              passing `false`.
+            - maxredirects (default = 5): sets the number of allowed redirects
+              to minimize looping due to misconfigured servers. When the number
+              is exceeded, the result of the last redirect is returned.
+          When the redirect is being followed, the same method and body values
+          are being sent in all cases except when 303 status is returned. In
+          that case the method is set to GET and the body is removed before the
+          redirect is followed. Note that if these (method/body) values are
+          provided as table fields, they will be modified in place.
+
+  FormatHttpDateTime(seconds:int) → rfc1123:str
+          Converts UNIX timestamp to an RFC1123 string that looks like this:
+          Mon, 29 Mar 2021 15:37:13 GMT. See formathttpdatetime.c.
+
+  FormatIp(uint32) → str
+          Turns integer like 0x01020304 into a string like 1.2.3.4. See also
+          ParseIp for the inverse operation.
+
+  GetAssetComment(path:str) → str
+          Returns comment text associated with asset in the ZIP central
+          directory. Also available as GetComment (deprecated).
+
+  GetAssetMode(path:str) → int
+          Returns UNIX-style octal mode for ZIP asset (or local file if the
+          -D flag is used)
+
+  GetAssetSize(path:str) → int
+          Returns byte size of uncompressed contents of ZIP asset (or local
+          file if the -D flag is used)
+
+  GetBody() → str
+          Returns the request message body if present or an empty string.
+          Also available as GetPayload (deprecated).
+
+  GetCookie(name:str) → str
+          Returns cookie value.
+
+  GetCryptoHash(name:str,payload:str[,key:str]) → str
+          Returns value of the specified cryptographic hash function. If the
+          key is provided, then HMAC value of the same function is returned.
+          The name can be one of the following strings: MD5, SHA1, SHA224,
+          SHA256, SHA384, SHA512, and BLAKE2B256.
+
+  GetRemoteAddr() → ip:uint32,port:uint16
+          Returns client ip4 address and port, e.g. 0x01020304,31337 would
+          represent 1.2.3.4:31337. This is the same as GetClientAddr except
+          it will use the ip:port from the X-Forwarded-For header, only if
+          IsPrivateIp or IsLoopbackIp return true. When multiple addresses
+          are present in the header, the last/right-most address is used.
+
+  GetClientAddr() → ip:uint32,port:uint16
+          Returns client socket ip4 address and port, e.g. 0x01020304,31337
+          would represent 1.2.3.4:31337. Please consider using GetRemoteAddr
+          instead, since the latter takes into consideration reverse proxy
+          scenarios.
+
+  GetClientFd() → int
+          Returns file descriptor being used for client connection.
+          This is useful for scripts that want to use unix:fork().
+
+  IsClientUsingSsl() → bool
+          Returns true if client connection has begun being managed by
+          the MbedTLS security layer. This is an important thing to
+          consider if a script is taking control of GetClientFd()
+
+  GetServerAddr() → ip:uint32,port:uint16
+          Returns address to which listening server socket is bound, e.g.
+          0x01020304,8080 would represent 1.2.3.4:8080. If -p 0 was supplied
+          as the listening port, then the port in this string will be
+          whatever number the operating system assigned.
+
+  GetDate() → seconds:int
+          Returns date associated with request that's used to generate the
+          Date header, which is now, give or take a second. The returned
+          value is a UNIX timestamp.
+
+  GetHeader(name:str) → value:str
+          Returns HTTP header. name is case-insensitive. The header value is
+          returned as a canonical UTF-8 string, with leading and trailing
+          whitespace trimmed, which was decoded from ISO-8859-1, which is
+          guaranteed to not have C0/C1 control sequences, with the exception
+          of the tab character. Leading and trailing whitespace is
+          automatically removed. In the event that the client suplies raw
+          UTF-8 in the HTTP message headers, the original UTF-8 sequence can
+          be losslessly restored by counter-intuitively recoding the
+          returned string back to Latin1. If the requested header is defined
+          by the RFCs as storing comma-separated values (e.g. Allow,
+          Accept-Encoding) and the field name occurs multiple times in the
+          message, then this function will fold those multiple entries into
+          a single string.
+
+  GetHeaders() → {name:str=value:str,...}
+          Returns HTTP headers as dictionary mapping header key strings to
+          their UTF-8 decoded values. The ordering of headers from the
+          request message is not preserved. Whether or not the same key can
+          repeat depends on whether or not it's a standard header, and if
+          so, if it's one of the ones that the RFCs define as repeatable.
+          See khttprepeatable.c. Those headers will not be folded. Standard
+          headers which aren't on that list, will be overwritten with the
+          last-occurring one during parsing. Extended headers are always
+          passed through exactly as they're received. Please consider using
+          GetHeader API if possible since it does a better job abstracting
+          these issues.
+
+  GetLogLevel() → int
+          Returns logger verbosity level. Likely return values are kLogDebug
+          > kLogVerbose > kLogInfo > kLogWarn > kLogError > kLogFatal.
+
+  GetHost() → str
+          Returns host associated with request. This will be the Host
+          header, if it's supplied. Otherwise it's the bind address.
+
+  GetHostOs() → str
+          Returns string that describes the host OS.
+
+          This can return:
+
+          - `"LINUX"`
+          - `"METAL"`
+          - `"WINDOWS"`
+          - `"XNU"`
+          - `"NETBSD"`
+          - `"FREEBSD"`
+          - `"OPENBSD"`
+
+  GetMonospaceWidth(str|char) → int
+          Returns monospace display width of string. This is useful for
+          fixed-width formatting. For example, CJK characters typically take
+          up two cells. This function takes into consideration combining
+          characters, which are discounted, as well as control codes and
+          ANSI escape sequences.
+
+  GetMethod() → str
+          Returns HTTP method. Normally this will be GET, HEAD, or POST in
+          which case redbean normalizes this value to its uppercase form.
+          Anything else that the RFC classifies as a "token" string is
+          accepted too, which might contain characters like &".
+
+  GetParams() → {{name:str[,value:str]},...}
+          Returns name=value parameters from Request-URL and
+          application/x-www-form-urlencoded message body in the order they
+          were received. This may contain duplicates. The inner array will
+          have either one or two items, depending on whether or not the
+          equals sign was used.
+
+  GetPath() → str
+          Returns the Request-URL path. This is guaranteed to begin with
+          "/". It is further guaranteed that no "//" or "/." exists in the
+          path. The returned value is returned as a UTF-8 string which was
+          decoded from ISO-8859-1. We assume that percent-encoded characters
+          were supplied by the client as UTF-8 sequences, which are returned
+          exactly as the client supplied them, and may therefore may contain
+          overlong sequences, control codes, NUL characters, and even
+          numbers which have been banned by the IETF. redbean takes those
+          things into consideration when performing path safety checks. It
+          is the responsibility of the caller to impose further restrictions
+          on validity, if they're desired.
+
+  GetEffectivePath() → str
+          Returns path as it was resolved by the routing algorithms, which
+          might contain the virtual host prepended if used.
+
+  GetScheme() → str
+          Returns scheme from Request-URL, if any.
+
+  GetSslIdentity() → str
+          Returns certificate subject or PSK identity from the current SSL
+          session. `nil` is returned for regular (non-SSL) connections.
+
+  GetStatus() → int
+          Returns current status (as set by an earlier SetStatus call) or
+          `nil` if the status hasn't been set yet.
+
+  GetTime() → seconds:number
+          Returns current time as a UNIX timestamp with 0.0001s precision.
+
+  GetUrl() → str
+          Returns the effective Request-URL as an ASCII string, where
+          illegal characters or UTF-8 is guaranteed to be percent encoded,
+          and has been normalized to include either the Host or
+          X-Forwarded-Host headers, if they exist, and possibly a scheme too
+          if redbean is being used as an HTTP proxy server. In the future
+          this API might change to return an object instead.
+
+  GetHttpVersion() → int
+          Returns the request HTTP protocol version, which can be 9 for
+          HTTP/0.9, 10 for HTTP/1.0, or 11 for HTTP/1.1. Also available
+          as GetVersion (deprecated).
+
+  GetRandomBytes([length:int]) → str
+          Returns string with the specified number of random bytes (1..256).
+          If no length is specified, then a string of length 16 is returned.
+
+  GetRedbeanVersion() → int
+          Returns the Redbean version in the format 0xMMmmpp, with major (MM),
+          minor (mm), and patch (pp) versions encoded. The version value 1.4
+          would be represented as 0x010400.
+
+  GetZipPaths([prefix:str]) → {path:str,...}
+          Returns paths of all assets in the zip central directory, prefixed
+          by a slash. If prefix parameter is provided, then only paths that
+          start with the prefix (case sensitive) are returned.
+
+  HasParam(name:str) → bool
+          Returns true if parameter with name was supplied in either the
+          Request-URL or an application/x-www-form-urlencoded message body.
+
+  HidePath(prefix:str)
+          Programs redbean / listing page to not display any paths beginning
+          with prefix. This function should only be called from /.init.lua.
+
+  IsPublicIp(uint32) → bool
+          Returns true if IP address is not a private network (10.0.0.0/8,
+          172.16.0.0/12, 192.168.0.0/16) and is not localhost (127.0.0.0/8).
+          Note: we intentionally regard TEST-NET IPs as public.
+
+  IsPrivateIp(uint32) → bool
+          Returns true if IP address is part of a private network
+          (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).
+
+  IsLoopbackIp(uint32) → bool
+          Returns true if IP address is part of the localhost network
+          (127.0.0.0/8).
+
+  IsCompressed(path:str) → bool
+          Returns true if ZIP artifact at path is stored on disk using
+          DEFLATE compression.
+
+  IndentLines(str[,int]) → str
+          Adds spaces to beginnings of multiline string. If the int
+          parameter is not supplied then 1 space will be added.
+
+  LoadAsset(path:str) → str
+          Returns contents of file as string. The asset may be sourced from
+          either the zip (decompressed) or the local filesystem if the -D
+          flag was used. If slurping large file into memory is a concern,
+          then consider using ServeAsset which can serve directly off disk.
+
+  StoreAsset(path:str,data:str[,mode:int])
+          Stores asset to executable's ZIP central directory. This currently
+          happens in an append-only fashion and is still largely in the
+          proof-of-concept stages. Currently only supported on Linux, XNU,
+          and FreeBSD.
+
+  Log(level:int,message:str)
+          Emits message string to log, if level is less than or equal to
+          GetLogLevel. If redbean is running in interactive mode, then this
+          will log to the console. If redbean is running as a daemon or the
+          -L LOGFILE flag is passed, then this will log to the file.
+          Reasonable values for level are kLogDebug > kLogVerbose > kLogInfo
+          > kLogWarn > kLogError > kLogFatal. The logger emits timestamps in
+          the local timezone with microsecond precision. If log entries are
+          emitted more frequently than once per second, then the log entry
+          will display a delta timestamp, showing how much time has elapsed
+          since the previous log entry. This behavior is useful for quickly
+          measuring how long various portions of your code take to execute.
+
+  ParseHttpDateTime(rfc1123:str) → seconds:int
+          Converts RFC1123 string that looks like this: Mon, 29 Mar 2021
+          15:37:13 GMT to a UNIX timestamp. See parsehttpdatetime.c.
+
+  ParseUrl(str) → URL
+          Parses URL, returning object having the following fields: scheme,
+          user, pass, host, port, path, params, fragment. This parser is
+          charset agnostic. Percent encoded bytes are decoded for all
+          fields. Returned values might contain things like NUL characters,
+          spaces, control codes, and non-canonical encodings. Absent can be
+          discerned from empty by checking if the pointer is set. There's no
+          failure condition for this routine. This is a permissive parser.
+          This doesn't normalize path segments like `.` or `..` so use
+          IsAcceptablePath() to check for those. No restrictions are imposed
+          beyond that which is strictly necessary for parsing. All the data
+          that is provided will be consumed to the one of the fields. Strict
+          conformance is enforced on some fields more than others, like
+          scheme, since it's the most non-deterministically defined field of
+          them all. Please note this is a URL parser, not a URI parser.
+          Which means we support everything everything the URI spec says we
+          should do except for the things we won't do, like tokenizing path
+          segments into an array and then nesting another array beneath each
+          of those for storing semicolon parameters. So this parser won't
+          make SIP easy. What it can do is parse HTTP URLs and most URIs
+          like data:opaque, better in fact than most things which claim to
+          be URI parsers.
+
+  EncodeUrl(URL) → str
+          This function is the inverse of ParseUrl. The output will always
+          be correctly formatted. The exception is if illegal characters are
+          supplied in the scheme field, since there's no way of escaping
+          those. Opaque parts are escaped as though they were paths, since
+          many URI parsers won't understand things like an unescaped
+          question mark in path.
+
+  ParseIp(str) → int
+          Converts IPv4 address string to integer, e.g. "1.2.3.4" →
+          0x01020304, or returns -1 for invalid inputs. See also FormatIp
+          for the inverse operation.
+
+  ProgramAddr(str)
+          Configures the address on which to listen. Can be used multiple
+          times to set more than one address.
+
+  ProgramBrand(str)
+          Changes HTTP Server header, as well as the <h1> title on the /
+          listing page. The brand string needs to be a UTF-8 value that's
+          encodable as ISO-8859-1. If the brand is changed to something
+          other than redbean, then the promotional links will be removed
+          from the listing page too. This function should only be called
+          from /.init.lua.
+
+  ProgramCache(seconds:int)
+          Configures Cache-Control and Expires header generation for static
+          asset serving. A negative value will disable the headers. Zero
+          means don't cache. Greater than zero asks public proxies and
+          browsers to cache for a given number of seconds. This should only
+          be called from /.init.lua.
+
+  ProgramCertificate(pem:str)
+          Same as the -C flag if called from .init.lua, e.g.
+          ProgramCertificate(LoadAsset("/.sign.crt")) for zip loading or
+          ProgramCertificate(Slurp("/etc/letsencrypt.lol/fullchain.pem")) for
+          local file system only.
+
+  ProgramHeader(name:str,value:str)
+          Appends HTTP header to the header buffer for all responses (whereas
+          SetHeader only appends a header to the current response buffer).
+          name is case-insensitive and restricted to non-space ASCII. value
+          is a UTF-8 string that must be encodable as ISO-8859-1. Leading and
+          trailing whitespace is trimmed automatically. Overlong characters
+          are canonicalized. C0 and C1 control codes are forbidden, with the
+          exception of tab. The header buffer is independent of the payload
+          buffer. This function disallows the setting of certain headers such
+          as Content-Range and Date, which are abstracted by the transport
+          layer.
+
+  ProgramPort(uint16)
+          Hard-codes the port number on which to listen, which can be any
+          number in the range 1..65535, or alternatively 0 to ask the
+          operating system to choose a port, which may be revealed later on
+          by GetServerAddr or the -z flag to stdout.
+
+  ProgramPrivateKey(pem:str)
+          Same as the -K flag if called from .init.lua, e.g.
+          ProgramPrivateKey(LoadAsset("/.sign.key")) for zip loading or
+          ProgramPrivateKey(Slurp("/etc/letsencrypt/fullchain.pem")) for
+          local file system only.
+
+  ProgramRedirect(code:int,src:str,location:str)
+          Configures fallback routing for paths which would otherwise return
+          404 Not Found. If code is 0 then the path is rewritten internally
+          as an accelerated redirect. If code is 301, 302, 307, or 308 then
+          a redirect response will be sent to the client. This should only
+          be called from /.init.lua.
+
+  ProgramSslTicketLifetime(seconds:int)
+          Defaults to 86400 (24 hours). This may be set to ≤0 to disable
+          SSL tickets. It's a good idea to use these since it increases
+          handshake performance 10x and eliminates a network round trip.
+
+  EvadeDragnetSurveillance(bool)
+          If this option is programmed then redbean will not transmit a
+          Server Name Indicator (SNI) when performing Fetch() requests.
+
+  ProgramSslPresharedKey(key:str,identity:str)
+          This function can be used to enable the PSK ciphersuites
+          which simplify SSL and enhance its performance in controlled
+          environments. `key` may contain 1..32 bytes of random binary
+          data and identity is usually a short plaintext string. The
+          first time this function is called, the preshared key will
+          be added to both the client and the server SSL configs. If
+          it's called multiple times, then the remaining keys will be
+          added to the server, which is useful if you want to assign
+          separate keys to each client, each of which needs a separate
+          identity too. If this function is called multiple times with
+          the same identity string, then the latter call will overwrite
+          the prior. If a preshared key is supplied and no certificates
+          or key-signing-keys are programmed, then redbean won't bother
+          auto-generating any serving certificates and will instead use
+          only PSK ciphersuites.
+
+  ProgramSslCiphersuite(name:str)
+          See https://redbean.dev/ for further details.
+
+  IsDaemon() → bool
+          Returns true if -d flag was passed to redbean.
+
+  ProgramUid(int)
+          Same as the -U flag if called from .init.lua for setuid()
+
+  ProgramGid(int)
+          Same as the -G flag if called from .init.lua for setgid()
+
+  ProgramDirectory(str)
+          Same as the -D flag if called from .init.lua for overlaying local
+          file system directories. This may be called multiple times. The
+          first directory programmed is preferred. These currently do not
+          show up in the index page listing.
+
+  ProgramLogMessages(bool)
+          Same as the -m flag if called from .init.lua for logging message
+          headers only.
+
+  ProgramLogBodies(bool)
+          Same as the -b flag if called from .init.lua for logging message
+          bodies as part of POST / PUT / etc. requests.
+
+  ProgramLogPath(str)
+          Same as the -L flag if called from .init.lua for setting the log
+          file path on the local file system. It's created if it doesn't
+          exist. This is called before de-escalating the uesr / group id.
+          The file is opened in append only mode. If the disk runs out of
+          space then redbean will truncate the log file if has access to
+          change the log file after daemonizing.
+
+  ProgramPidPath(str)
+          Same as the -P flag if called from .init.lua for setting the pid
+          file path on the local file system. It's useful for reloading
+          daemonized redbean using `kill -HUP $(cat /var/run/redbean.pid)`
+          or terminating redbean with `kill $(cat /var/run/redbean.pid)`
+          which will gracefully terminate all clients. Sending the TERM
+          signal twice will cause a forceful shutdown, which might make
+          someone with a slow internet connection who's downloading big
+          files unhappy.
+
+  ProgramUniprocess([bool]) → bool
+          Same as the -u flag if called from .init.lua. Can be used to
+          configure the uniprocess mode. The current value is returned.
+
+  Slurp(filename:str) → str
+          Reads file data from local file system.
+
+  Sleep(seconds:number)
+          Sleeps the specified number of seconds (can be fractional). The
+          smallest interval is a microsecond.
+
+  Route([host:str,[path:str]])
+          Instructs redbean to follow the normal HTTP serving path. This
+          function is useful when writing an OnHttpRequest handler, since
+          that overrides the serving path entirely. So if the handler
+          decides it doesn't want to do anything, it can simply call this
+          function, to hand over control back to the redbean core. By
+          default, the host and path arguments are supplied from the
+          resolved GetUrl value. This handler always resolves, since it will
+          generate a 404 Not Found response if redbean couldn't find an
+          appropriate endpoint.
+
+  RouteHost([host:str,[path:str]]) → bool
+          This is the same as Route, except it only implements the subset of
+          request routing needed for serving virtual-hosted assets, where
+          redbean tries to prefix the path with the hostname when looking up
+          a file. This function returns true if the request was resolved. If
+          it was resolved, then your OnHttpRequest request handler can still
+          set additional headers.
+
+  RoutePath([path:str]) → bool
+          This is the same as Route, except it only implements the subset of
+          request routing needed for serving assets. This function returns
+          true if the request was resolved. If it was resolved, then your
+          OnHttpRequest request handler can still set additional headers.
+          Note that the asset needs to have "read other" permissions;
+          otherwise this function logs a warning and returns 403 Forbidden.
+          If this is undesirable, use GetAssetMode and ServeAsset to bypass
+          the check.
+
+  ServeAsset(path:str)
+          Instructs redbean to serve static asset at path. This function
+          causes what would normally happen outside a dynamic handler to
+          happen. The asset can be sourced from either the zip or local
+          filesystem if -D is used. This function is mutually exclusive with
+          SetStatus and other Serve* functions.
+
+  ServeError(code:int[,reason:str])
+          Instructs redbean to serve a boilerplate error page. This takes
+          care of logging the error, setting the reason phrase, and adding a
+          payload. This function is mutually exclusive with SetStatus and
+          other Serve* functions.
+
+  ServeRedirect(code:int,location:str)
+          Instructs redbean to return the specified redirect code along with
+          the Location header set. This function is mutually exclusive with
+          SetStatus and other Serve* functions.
+
+  SetLogLevel(level:int)
+          Sets logger verbosity. Reasonable values for level are kLogDebug >
+          kLogVerbose > kLogInfo > kLogWarn > kLogError > kLogFatal. This is
+          reset at the end of the http request, so it can be used to disable
+          access log and message logging.
+
+  VisualizeControlCodes(str) → str
+          Replaces C0 control codes with their UNICODE pictures
+          representation. This function also canonicalizes overlong
+          encodings. C1 control codes are replaced with a JavaScript-like
+          escape sequence.
+
+  Underlong(str) → str
+          Canonicalizes overlong encodings.
+
+  Crc32(initial:int,data:str) → int
+          Computes 32-bit CRC-32 used by zip/zlib/gzip/etc.
+
+  Crc32c(initial:int,data:str) → int
+          Computes 32-bit Castagnoli Cyclic Redundancy Check.
+
+  Md5(str) → str
+          Computes MD5 checksum, returning 16 bytes of binary.
+
+  Sha1(str) → str
+          Computes SHA1 checksum, returning 20 bytes of binary.
+
+  Sha224(str) → str
+          Computes SHA224 checksum, returning 28 bytes of binary.
+
+  Sha256(str) → str
+          Computes SHA256 checksum, returning 32 bytes of binary.
+
+  Sha384(str) → str
+          Computes SHA384 checksum, returning 48 bytes of binary.
+
+  Sha512(str) → str
+          Computes SHA512 checksum, returning 64 bytes of binary.
+
+  Bsf(x:int) → int
+          Returns position of first bit set. Passing 0 will raise an error.
+          Same as the Intel x86 instruction BSF.
+
+  Bsr(x:int) → int
+          Returns binary logarithm of 𝑥. Passing 0 will raise an error. Same
+          as the Intel x86 instruction BSR.
+
+  Popcnt(x:int) → int
+          Returns number of bits set in integer.
+
+  Rdtsc() → int
+          Returns CPU timestamp counter.
+
+  Lemur64() → int
+          Returns fastest pseudorandom non-cryptographic random number. This
+          linear congruential generator passes practrand and bigcrush.
+
+  Rand64() → int
+          Returns nondeterministic pseudorandom non-cryptographic number. This
+          linear congruential generator passes practrand and bigcrush. This
+          generator is safe across fork(), threads, and signal handlers.
 
+  Rdrand() → int
+          Returns 64-bit hardware random integer from RDRND instruction, with
+          automatic fallback to getrandom() if not available.
+
+  Rdseed() → int
+          Returns 64-bit hardware random integer from RDSEED instruction, with
+          automatic fallback to RDRND and getrandom() if not available.
+
+  GetCpuCount() → int
+          Returns CPU core count or 0 if it couldn't be determined.
+
+  GetCpuCore() → int
+          Returns 0-indexed CPU core on which process is currently scheduled.
+
+  GetCpuNode() → int
+          Returns 0-indexed NUMA node on which process is currently scheduled.
+
+  Decimate(data) → int
+          Shrinks byte buffer in half using John Costella's magic kernel.
+          This downscales data 2x using an eight-tap convolution, e.g.
+
+              >: Decimate(b'\\xff\\xff\\x00\\x00\\xff\\xff\\x00\\x00\\xff\\xff\\x00\\x00')
+              b'\\xff\\x00\\xff\\x00\\xff\\x00'
+
+          This is very fast if SSSE3 is available (Intel 2004+ / AMD 2011+).
+
+  MeasureEntropy(data) → float
+          Returns Shannon entropy of array. This gives you an idea of
+          the density of information. Cryptographic random should be in
+          the ballpark of 7.9 whereas plaintext will be more like 4.5.
+
+  Benchmark(func[, count[, maxattempts]])
+      └─→ nanos:real, ticks:int, overhead-ticks:int, tries:int
+
+    Performs microbenchmark.
+
+    The first value returned is the average number of nanoseconds that
+    `func` needed to execute. Nanoseconds are computed from RDTSC tick
+    counts, using an approximation that's measured beforehand with the
+    unix.clock_gettime() function.
+
+    The `ticks` result is the canonical average number of clock ticks.
+
+    This subroutine will subtract whatever the overhead happens to be
+    for benchmarking a function that does nothing. This overhead value
+    will be reported in the result.
+
+    `tries` indicates if your microbenchmark needed to be repeated,
+    possibly because your system is under load and the benchmark was
+    preempted by the operating system, or moved to a different core.
+
+  oct(int)
+      └─→ str
+
+    Formats string as octal integer literal string. If the provided
+    value is zero, the result will be `"0"`. Otherwise the resulting
+    value will be the zero-prefixed octal string. The result is
+    currently modulo 2^64. Negative numbers are converted to unsigned.
+
+  hex(int)
+      └─→ str
+
+    Formats string as hexadecimal integer literal string. If the
+    provided value is zero, the result will be `"0"`. Otherwise the
+    resulting value will be the `"0x"`-prefixed hex string. The result
+    is currently modulo 2^64. Negative numbers are converted to
+    unsigned.
+
+  bin(int)
+      └─→ str
+
+    Formats string as binary integer literal string. If the provided
+    value is zero, the result will be `"0"`. Otherwise the resulting
+    value will be the `"0b"`-prefixed binary str. The result is
+    currently modulo 2^64. Negative numbers are converted to unsigned.

+LSQLITE3 MODULE
+
+  Please refer to the LuaSQLite3 Documentation.
+
+  For example, you could put the following in your /.init.lua file:
+
+    sqlite3 = require "lsqlite3"
+    db = sqlite3.open_memory()
+    db:exec[[
+      CREATE TABLE test (
+        id INTEGER PRIMARY KEY,
+        content TEXT
+      );
+      INSERT INTO test (content) VALUES ('Hello World');
+      INSERT INTO test (content) VALUES ('Hello Lua');
+      INSERT INTO test (content) VALUES ('Hello Sqlite3');
+    ]]
+
+  Then, your Lua server pages or OnHttpRequest handler may perform SQL
+  queries by accessing the db global. The performance is good too, at about
+  400k qps.
+
+    for row in db:nrows("SELECT * FROM test") do
+       Write(row.id.." "..row.content.."<br>")
+    end
+
+  redbean supports a subset of what's defined in the upstream LuaSQLite3
+  project. Most of the unsupported APIs relate to pointers and database
+  notification hooks.
+
+  redbean also currently disables SQLite features which don't make sense for
+  production serving, such as ALTER, VACUUM, ANALYZE, etc. For that reason
+  we provide an APE build of the SQLite shell which you can use to
+  administrate your redbean database. See the sqlite3.com download above.

+
+RE MODULE
+
+  This module exposes an API for POSIX regular expressions which enable you
+  to validate input, search for substrings, extract pieces of strings, etc.
+  Here's a usage example:
+
+    # Example IPv4 Address Regular Expression (see also ParseIP)
+    p = re.compile([[^([0-9]{1,3})\.([0-9]{1,3})\.([0-9]{1,3})\.([0-9]{1,3})$]])
+    m,a,b,c,d = p:search(𝑠)
+    if m then
+      print("ok", tonumber(a), tonumber(b), tonumber(c), tonumber(d))
+    else
+      print("not ok")
+    end
+
+  re.search(regex:str,text:str[,flags:int]) → [match[,group_1,...]]
+          Shortcut for re.compile plus regex_t*:search.
+
+  re.compile(regex:str[,flags:int]) → regex_t*
+          Compiles regular expression, using the POSIX extended syntax. This
+          has an O(2^𝑛) cost, so it's a good idea to do this from your
+          /.init.lua file. Flags may contain re.BASIC, re.ICASE, re.NOSUB,
+          and/or re.NEWLINE. See also regcomp() from libc.
+
+  regex_t*:search(text:str[,flags:int]) → [match[,group_1,...]]
+          Executes regular expression. This has an O(𝑛) cost. This returns
+          nothing (nil) if the pattern doesn't match anything. Otherwise it
+          pushes the matched substring and any parenthesis-captured values
+          too. Flags may contain re.NOTBOL or re.NOTEOL to indicate whether
+          or not text should be considered at the start and/or end of a
+          line.
+
+  re.BASIC
+          Use this flag if you prefer the default POSIX regex syntax. We use
+          extended regex notation by default. For example, an extended
+          regular expression for matching an IP address might look like
+          ([0-9]*)\.([0-9]*)\.([0-9]*)\.([0-9]*) whereas with basic syntax
+          it would look like \([0-9]*\)\.\([0-9]*\)\.\([0-9]*\)\.\([0-9]*\).
+          This flag may only be used with re.compile and re.search.
+
+  re.ICASE
+          Use this flag to make your pattern case ASCII case-insensitive.
+          This means [a-z] will mean the same thing as [A-Za-z]. This flag
+          may only be used with re.compile and re.search.
+
+  re.NEWLINE
+          Use this flag to change the handling of NEWLINE (\x0a) characters.
+          When this flag is set, (1) a NEWLINE shall not be matched by a "."
+          or any form of a non-matching list, (2) a "^" shall match the
+          zero-length string immediately after a NEWLINE (regardless of
+          re.NOTBOL), and (3) a "$" shall match the zero-length string
+          immediately before a NEWLINE (regardless of re.NOTEOL).
+
+  re.NOSUB
+          Causes re.search to only report success and failure. This is
+          reported via the API by returning empty string for success. This
+          flag may only be used with re.compile and re.search.

+UNIX MODULE
+
+  This module exposes the low-level System Five system call interface.
+  This module works on all supported platforms, including Windows NT.
+
+  unix.open(path:str, flags:int[, mode:int[, dirfd:int]])
+      ├─→ fd:int
+      └─→ nil, unix.Errno
+
+    Opens file.
+
+    Returns a file descriptor integer that needs to be closed, e.g.
+
+        fd = assert(unix.open("/etc/passwd", unix.O_RDONLY))
+        print(unix.read(fd))
+        unix.close(fd)
+
+    `flags` should have one of:
+
+    - `O_RDONLY`:     open for reading
+    - `O_WRONLY`:     open for writing
+    - `O_RDWR`:       open for reading and writing
+
+    The following values may also be OR'd into `flags`:
+
+     - `O_CREAT`      create file if it doesn't exist
+     - `O_TRUNC`      automatic ftruncate(fd,0) if exists
+     - `O_CLOEXEC`    automatic close() upon execve()
+     - `O_EXCL`       exclusive access (see below)
+     - `O_APPEND`     open file for append only
+     - `O_NONBLOCK`   asks read/write to fail with EAGAIN rather than block
+     - `O_DIRECT`     it's complicated (not supported on Apple and OpenBSD)
+     - `O_DIRECTORY`  useful for stat'ing (hint on UNIX but required on NT)
+     - `O_TMPFILE`    try to make temp more secure (Linux and Windows only)
+     - `O_NOFOLLOW`   fail if it's a symlink (zero on Windows)
+     - `O_DSYNC`      it's complicated (zero on non-Linux/Apple)
+     - `O_RSYNC`      it's complicated (zero on non-Linux/Apple)
+     - `O_PATH`       it's complicated (zero on non-Linux)
+     - `O_VERIFY`     it's complicated (zero on non-FreeBSD)
+     - `O_SHLOCK`     it's complicated (zero on non-BSD)
+     - `O_EXLOCK`     it's complicated (zero on non-BSD)
+     - `O_NOATIME`    don't record access time (zero on non-Linux)
+     - `O_RANDOM`     hint random access intent (zero on non-Windows)
+     - `O_SEQUENTIAL` hint sequential access intent (zero on non-Windows)
+     - `O_COMPRESSED` ask fs to abstract compression (zero on non-Windows)
+     - `O_INDEXED`    turns on that slow performance (zero on non-Windows)
+
+     There are three regular combinations for the above flags:
+
+     - `O_RDONLY`: Opens existing file for reading. If it doesn't
+       exist then nil is returned and errno will be `ENOENT` (or in
+       some other cases `ENOTDIR`).
+
+     - `O_WRONLY|O_CREAT|O_TRUNC`: Creates file. If it already
+       exists, then the existing copy is destroyed and the opened
+       file will start off with a length of zero. This is the
+       behavior of the traditional creat() system call.
+
+     - `O_WRONLY|O_CREAT|O_EXCL`: Create file only if doesn't exist
+       already. If it does exist then `nil` is returned along with
+       `errno` set to `EEXIST`.
+
+    `dirfd` defaults to to `unix.AT_FDCWD` and may optionally be set to
+    a directory file descriptor to which `path` is relative.
+
+    Returns `ENOENT` if `path` doesn't exist.
+
+    Returns `ENOTDIR` if `path` contained a directory component that
+    wasn't a directory.
+
+  unix.close(fd:int)
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Closes file descriptor.
+
+  unix.read(fd:int[, bufsiz:str[, offset:int]])
+      ├─→ data:str
+      └─→ nil, unix.Errno
+
+    Reads from file descriptor.
+
+  unix.write(fd:int, data:str[, offset:int])
+      ├─→ wrotebytes:int
+      └─→ nil, unix.Errno
+
+    Writes to file descriptor.
+
+  unix.exit([exitcode:int])
+      └─→ ⊥
+
+    Invokes `_Exit(exitcode)` on the process. This will immediately
+    halt the current process. Memory will be freed. File descriptors
+    will be closed. Any open connections it owns will be reset. This
+    function never returns.
+
+  unix.environ()
+      └─→ {str,...}
+
+    Returns raw environment variables.
+
+    This allocates and constructs the C/C++ `environ` variable as a Lua
+    table consisting of string keys and string values.
+
+    This data structure preserves casing. On Windows NT, by convention,
+    environment variable keys are treated in a case-insensitive way. It
+    is the responsibility of the caller to consider this.
+
+    This data structure preserves valueless variables. It's possible on
+    both UNIX and Windows to have an environment variable without an
+    equals, even though it's unusual.
+
+    This data structure preserves duplicates. For example, on Windows,
+    there's some irregular uses of environment variables such as how the
+    command prompt inserts multiple environment variables with empty
+    string as keys, for its internal bookkeeping.
+
+  unix.fork()
+      ├─┬─→ 0
+      │ └─→ childpid:int
+      └─→ nil, unix.Errno
+
+    Creates a new process mitosis style.
+
+    This system call returns twice. The parent process gets the nonzero
+    pid. The child gets zero.
+
+    Here's some benchmarks for fork() performance across platforms:
+
+        Linux 5.4 fork      l:     97,200𝑐    31,395𝑛𝑠  [metal]
+        FreeBSD 12 fork     l:    236,089𝑐    78,841𝑛𝑠  [vmware]
+        Darwin 20.6 fork    l:    295,325𝑐    81,738𝑛𝑠  [metal]
+        NetBSD 9 fork       l:  5,832,027𝑐 1,947,899𝑛𝑠  [vmware]
+        OpenBSD 6.8 fork    l: 13,241,940𝑐 4,422,103𝑛𝑠  [vmware]
+        Windows10 fork      l: 18,802,239𝑐 6,360,271𝑛𝑠  [metal]
+
+    One of the benefits of using fork() is it creates an isolation
+    barrier between the different parts of your app. This can lead to
+    enhanced reliability and security. For example, redbean uses fork so
+    it can wipe your ssl keys from memory before handing over control to
+    request handlers that process untrusted input. It also ensures that
+    if your Lua app crashes, it won't take down the server as a whole.
+    Hence it should come as no surprise that fork() would go slower on
+    operating systems that have more security features. So depending on
+    your use case, you can choose the operating system that suits you.
+
+  unix.commandv(prog:str)
+      ├─→ path:str
+      └─→ nil, unix.Errno
+
+    Performs `$PATH` lookup of executable.
+
+        unix = require 'unix'
+        prog = assert(unix.commandv('ls'))
+        unix.execve(prog, {prog, '-hal', '.'}, {'PATH=/bin'})
+        unix.exit(127)
+
+    We automatically suffix `.com` and `.exe` for all platforms when
+    path searching. By default, the current directory is not on the
+    path. If `prog` is an absolute path, then it's returned as-is. If
+    `prog` contains slashes then it's not path searched either and will
+    be returned if it exists.
+
+  unix.execve(prog:str[, args:List<*>, env:List<*>])
+      └─→ nil, unix.Errno
+
+    Exits current process, replacing it with a new instance of the
+    specified program. `prog` needs to be an absolute path, see
+    commandv(). `env` defaults to to the current `environ`. Here's
+    a basic usage example:
+
+        unix.execve("/bin/ls", {"/bin/ls", "-hal"}, {"PATH=/bin"})
+        unix.exit(127)
+
+    `prog` needs to be the resolved pathname of your executable. You
+    can use commandv() to search your `PATH`.
+
+    `args` is a string list table. The first element in `args`
+    should be `prog`. Values are coerced to strings. This parameter
+    defaults to `{prog}`.
+
+    `env` is a string list table. Values are coerced to strings. No
+    ordering requirement is imposed. By convention, each string has its
+    key and value divided by an equals sign without spaces. If this
+    paremeter is not specified, it'll default to the C/C++ `environ`
+    variable which is inherited from the shell that launched redbean.
+    It's the responsibility of the user to supply a sanitized environ
+    when spawning untrusted processes.
+
+    execve() is normally called after fork() returns 0. If that isn't
+    the case, then your redbean worker will be destroyed.
+
+    This function never returns on success.
+
+    `EAGAIN` is returned if you've enforced a max number of
+    processes using `setrlimit(RLIMIT_NPROC)`.
+
+  unix.dup(oldfd:int[, newfd:int[, flags:int]])
+      ├─→ newfd:int
+      └─→ nil, unix.Errno
+
+    Duplicates file descriptor.
+
+    `newfd` defaults to the lowest number available file descriptor.
+    If the new number is specified and it's already open, then it'll
+    be silently closed before the duplication happens.
+
+    `flags` can have `O_CLOEXEC` which means the returned file
+    descriptors will be automatically closed upon execve().
+
+  unix.pipe([flags:int])
+      ├─→ reader:int, writer:int
+      └─→ nil, unix.Errno
+
+    Creates fifo which enables communication between processes.
+
+    `flags` can have any of
+
+    - `O_CLOEXEC`: Automatically close file descriptor upon execve()
+
+    - `O_NONBLOCK`: Request `EAGAIN` be raised rather than blocking
+
+    - `O_DIRECT`: Enable packet mode w/ atomic reads and writes, so long
+      as they're no larger than `PIPE_BUF` (guaranteed to be 512+ bytes)
+      with support limited to Linux, Windows NT, FreeBSD, and NetBSD.
+
+    Returns two file descriptors: one for reading and one for writing.
+
+    Here's an example of how pipe(), fork(), dup(), etc. may be used
+    to serve an HTTP response containing the output of a subprocess.
+
+        local unix = require "unix"
+        ls = assert(unix.commandv("ls"))
+        reader, writer = assert(unix.pipe())
+        if assert(unix.fork()) == 0 then
+           unix.close(1)
+           unix.dup(writer)
+           unix.close(writer)
+           unix.close(reader)
+           unix.execve(ls, {ls, "-Shal"})
+           unix.exit(127)
+        else
+           unix.close(writer)
+           SetHeader('Content-Type', 'text/plain')
+           while true do
+              data, err = unix.read(reader)
+              if data then
+                 if data ~= "" then
+                    Write(data)
+                 else
+                    break
+                 end
+              elseif err:errno() ~= EINTR then
+                 Log(kLogWarn, tostring(err))
+                 break
+              end
+           end
+           assert(unix.close(reader))
+           assert(unix.wait())
+        end
+
+  unix.wait([pid:int[, options:int]])
+      ├─→ pid:int, wstatus:int, unix.Rusage
+      └─→ nil, unix.Errno
+
+    Waits for subprocess to terminate.
+
+    `pid` defaults to `-1` which means any child process. Setting
+    `pid` to `0` is equivalent to `-getpid()`. If `pid < -1` then
+    that means wait for any pid in the process group `-pid`. Then
+    lastly if `pid > 0` then this waits for a specific process id
+
+    Options may have `WNOHANG` which means don't block, check for
+    the existence of processes that are already dead (technically
+    speaking zombies) and if so harvest them immediately.
+
+    Returns the process id of the child that terminated. In other
+    cases, the returned `pid` is nil and `errno` is non-nil.
+
+    The returned `wstatus` contains information about the process
+    exit status. It's a complicated integer and there's functions
+    that can help interpret it. For example:
+
+        -- wait for zombies
+        -- traditional technique for SIGCHLD handlers
+        while true do
+           pid, status = unix.wait(-1, unix.WNOHANG)
+           if pid then
+              if unix.WIFEXITED(status) then
+                 print('child', pid, 'exited with',
+                       unix.WEXITSTATUS(status))
+              elseif unix.WIFSIGNALED(status) then
+                 print('child', pid, 'crashed with',
+                       unix.strsignal(unix.WTERMSIG(status)))
+              end
+           elseif status:errno() == unix.ECHILD then
+              Log(kLogDebug, 'no more zombies')
+              break
+           else
+              Log(kLogWarn, tostring(err))
+              break
+           end
+        end
+
+  unix.WIFEXITED(wstatus:int)
+      └─→ bool
+
+    Returns true if process exited cleanly.
+
+  unix.WEXITSTATUS(wstatus:int)
+      └─→ exitcode:uint8
+
+    Returns code passed to exit() assuming `WIFEXITED(wstatus)` is true.
+
+  unix.WIFSIGNALED(wstatus:int)
+      └─→ bool
+
+    Returns true if process terminated due to a signal.
+
+  unix.WTERMSIG(wstatus:int)
+      └─→ sig:uint8
+
+    Returns signal that caused process to terminate assuming
+    `WIFSIGNALED(wstatus)` is true.
+
+  unix.getpid()
+      └─→ pid:int
+
+    Returns process id of current process.
+
+    This function does not fail.
+
+  unix.getppid()
+      └─→ pid:int
+
+    Returns process id of parent process.
+
+    This function does not fail.
+
+  unix.kill(pid:int, sig:int)
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Sends signal to process(es).
+
+    The impact of this action can be terminating the process, or
+    interrupting it to request something happen.
+
+    `pid` can be:
+
+    - `pid > 0` signals one process by id
+    - `== 0`    signals all processes in current process group
+    - `-1`      signals all processes possible (except init)
+    - `< -1`    signals all processes in -pid process group
+
+    `sig` can be:
+
+    - `0`       checks both if pid exists and we can signal it
+    - `SIGINT`  sends ctrl-c keyboard interrupt
+    - `SIGQUIT` sends backtrace and exit signal
+    - `SIGTERM` sends shutdown signal
+    - etc.
+
+    Windows NT only supports the kill() signals required by the ANSI C89
+    standard, which are `SIGINT` and `SIGQUIT`. All other signals on the
+    Windows platform that are sent to another process via kill() will be
+    treated like `SIGKILL`.
+
+  unix.raise(sig:int)
+      ├─→ rc:int
+      └─→ nil, unix.Errno
+
+    Triggers signal in current process.
+
+    This is pretty much the same as `kill(getpid(), sig)`.
+
+  unix.access(path:str, how:int[, flags:int[, dirfd:int]])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Checks if effective user of current process has permission to access
+    file. `how` can be `R_OK`, `W_OK`, `X_OK`, or `F_OK` to check for
+    read, write, execute, and existence respectively.
+
+    `flags` may have any of:
+
+    - `AT_SYMLINK_NOFOLLOW`: do not follow symbolic links.
+
+  unix.mkdir(path:str[, mode:int[, dirfd:int]])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Makes directory.
+
+    `path` is the path of the directory you wish to create.
+
+    `mode` is octal permission bits, e.g. `0755`.
+
+    Fails with `EEXIST` if `path` already exists, whether it be a
+    directory or a file.
+
+    Fails with `ENOENT` if the parent directory of the directory you
+    want to create doesn't exist. For making `a/really/long/path/`
+    consider using makedirs() instead.
+
+    Fails with `ENOTDIR` if a parent directory component existed that
+    wasn't a directory.
+
+    Fails with `EACCES` if the parent directory doesn't grant write
+    permission to the current user.
+
+    Fails with `ENAMETOOLONG` if the path is too long.
+
+  unix.makedirs(path:str[, mode:int])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Makes directories.
+
+    `path` is the path of the directory you wish to create.
+
+    `mode` is octal permission bits, e.g. `0755`.
+
+    Unlike mkdir() this convenience wrapper will automatically create
+    parent parent directories as needed.
+
+  unix.chdir(path:str)
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Changes current directory to `path`.
+
+  unix.unlink(path:str[, dirfd:int])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Removes file at `path`.
+
+    If `path` refers to a symbolic link, the link is removed.
+
+    Returns `EISDIR` if `path` refers to a directory. See rmdir().
+
+  unix.rmdir(path:str[, dirfd:int])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Removes empty directory at `path`.
+
+    Returns `ENOTDIR` if `path` isn't a directory, or a path component
+    in `path` exists yet wasn't a directory.
+
+  unix.rename(oldpath:str, newpath:str[, olddirfd:int, newdirfd:int])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Renames file or directory.
+
+  unix.link(existingpath:str, newpath:str[, flags:int[, olddirfd, newdirfd]])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Creates hard link, so your underlying inode has two names.
+
+  unix.symlink(target:str, linkpath:str[, newdirfd:int])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Creates symbolic link.
+
+    On Windows NT a symbolic link is called a "reparse point" and can
+    only be created from an administrator account. Your redbean will
+    automatically request the appropriate permissions.
+
+  unix.readlink(path:str[, dirfd:int])
+      ├─→ content:str
+      └─→ nil, unix.Errno
+
+    Reads contents of symbolic link.
+
+    Note that broken links are supported on all platforms. A symbolic
+    link can contain just about anything. It's important to not assume
+    that `content` will be a valid filename.
+
+    On Windows NT, this function transliterates `\` to `/` and
+    furthermore prefixes `//?/` to WIN32 DOS-style absolute paths,
+    thereby assisting with simple absolute filename checks in addition
+    to enabling one to exceed the traditional 260 character limit.
+
+  unix.realpath(path:str)
+      ├─→ path:str
+      └─→ nil, unix.Errno
+
+    Returns absolute path of filename, with `.` and `..` components
+    removed, and symlinks will be resolved.
+
+  unix.chown(path:str, uid:int, gid:int[, flags:int[, dirfd:int]])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Changes user and group on file.
+
+    Returns `ENOSYS` on Windows NT.
+
+  unix.chmod(path:str, mode:int[, flags:int[, dirfd:int]])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Changes mode bits on file.
+
+    On Windows NT the chmod system call only changes the read-only
+    status of a file.
+
+  unix.getcwd()
+      ├─→ path:str
+      └─→ nil, unix.Errno
+
+    Returns current working directory.
+
+    On Windows NT, this function transliterates `\` to `/` and

+
+  unix.fcntl(fd:int, cmd:int, ...)
+      ├─→ ...
+      └─→ nil, unix.Errno
+
+    Manipulates file descriptor.
+
+    Setting `cmd` to `F_GETFD`, `F_SETFD`, `F_GETFL` or `F_SETFL`
+    lets you query and/or change the status of file descriptors. For
+    example, it's possible using this to change `FD_CLOEXEC`.
+
+    [work in progress] POSIX advisory locks can be controlled by setting
+    `cmd` to `F_UNLCK`, `F_RDLCK`, `F_WRLCK`, `F_SETLK`, or `F_SETLKW`.
+
+  unix.getsid(pid:int)
+      ├─→ sid:int

+
+  unix.setpgrp()
+      ├─→ pgid:int
+      └─→ nil, unix.Errno
+

+
+  unix.setpgid(pid:int, pgid:int)
+      ├─→ true
+      └─→ nil, unix.Errno

+
+  unix.setsid()
+      ├─→ sid:int
+      └─→ nil, unix.Errno
+
+    Sets session id.
+
+    This function can be used to create daemons.
+
+    Fails with `ENOSYS` on Windows NT.
+
+  unix.getuid()
+      └─→ uid:int
+
+    Gets real user id.
+
+    On Windows this system call is polyfilled by running GetUserNameW()
+    through Knuth's multiplicative hash.
+
+    This function does not fail.
+
+  unix.getgid()
+      └─→ gid:int
+
+    Sets real group id.
+
+    On Windows this system call is polyfilled as getuid().
+
+    This function does not fail.
+
+  unix.geteuid()
+      └─→ uid:int
+
+    Gets effective user id.
+
+    For example, if your redbean is a setuid binary, then getuid() will
+    return the uid of the user running the program, and geteuid() shall
+    return zero which means root, assuming that's the file owning user.
+
+    On Windows this system call is polyfilled as getuid().
+
+    This function does not fail.
+
+  unix.getegid()
+      └─→ gid:int
+
+    Gets effective group id.
+
+    On Windows this system call is polyfilled as getuid().
+
+    This function does not fail.
+
+  unix.chroot(path:str)
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Changes root directory.
+
+    Returns `ENOSYS` on Windows NT.
+
+  unix.setuid(uid:int)
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Sets user id.
+
+    One use case for this function is dropping root privileges. Should
+    you ever choose to run redbean as root and decide not to use the
+    `-G` and `-U` flags, you can replicate that behavior in the Lua
+    processes you spawn as follows:
+
+        ok, err = unix.setgid(1000)  -- check your /etc/groups
+        if not ok then Log(kLogFatal, tostring(err)) end
+        ok, err = unix.setuid(1000)  -- check your /etc/passwd
+        if not ok then Log(kLogFatal, tostring(err)) end
+
+    If your goal is to relinquish privileges because redbean is a setuid
+    binary, then things are more straightforward:
+
+        ok, err = unix.setgid(unix.getgid())
+        if not ok then Log(kLogFatal, tostring(err)) end
+        ok, err = unix.setuid(unix.getuid())
+        if not ok then Log(kLogFatal, tostring(err)) end
+
+    See also the setresuid() function and be sure to refer to your local
+    system manual about the subtleties of changing user id in a way that
+    isn't restorable.
+
+    Returns `ENOSYS` on Windows NT if `uid` isn't `getuid()`.
+
+  unix.setgid(gid:int)
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Sets group id.
+

+
+  unix.setresuid(real:int, effective:int, saved:int)
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Sets real, effective, and saved user ids.
+
+    If any of the above parameters are -1, then it's a no-op.
+
+    Returns `ENOSYS` on Windows NT.
+    Returns `ENOSYS` on Macintosh and NetBSD if `saved` isn't -1.
+
+  unix.setresgid(real:int, effective:int, saved:int)
+      ├─→ true
+      └─→ nil, unix.Errno

+
+    If any of the above parameters are -1, then it's a no-op.
+
+    Returns `ENOSYS` on Windows NT.
+    Returns `ENOSYS` on Macintosh and NetBSD if `saved` isn't -1.
+
+  unix.umask(newmask:int)
+      └─→ oldmask:int
+
+    Sets file permission mask and returns the old one.
+
+    This is used to remove bits from the `mode` parameter of functions
+    like open() and mkdir(). The masks typically used are 027 and 022.
+    Those masks ensure that, even if a file is created with 0666 bits,
+    it'll be turned into 0640 or 0644 so that users other than the owner
+    can't modify it.
+
+    To read the mask without changing it, try doing this:
+
+        mask = unix.umask(027)
+        unix.umask(mask)
+
+    On Windows NT this is a no-op and `mask` is returned.
+
+    This function does not fail.
+
+  unix.syslog(priority:int, msg:str)
+
+    Generates a log message, which will be distributed by syslogd.
+
+    `priority` is a bitmask containing the facility value and the level
+    value. If no facility value is ORed into priority, then the default
+    value set by openlog() is used. If set to NULL, the program name is
+    used. Level is one of `LOG_EMERG`, `LOG_ALERT`, `LOG_CRIT`,
+    `LOG_ERR`, `LOG_WARNING`, `LOG_NOTICE`, `LOG_INFO`, `LOG_DEBUG`.
+
+    This function currently works on Linux, Windows, and NetBSD. On
+    WIN32 it uses the ReportEvent() facility.
+
+  unix.clock_gettime([clock:int])
+      ├─→ seconds:int, nanos:int

+
+    Returns `EINVAL` if clock isn't supported on platform.
+
+    This function only fails if `clock` is invalid.
+
+    This function goes fastest on Linux and Windows.

+      ├─→ newposbytes:int
+      └─→ nil, unix.Errno
+
+    Seeks to file position.
+
+    `whence` can be one of:
+
+    - `SEEK_SET`: Sets the file position to `offset`
+    - `SEEK_CUR`: Sets the file position to `position + offset`
+    - `SEEK_END`: Sets the file position to `filesize + offset`
+
+    Returns the new position relative to the start of the file.
+
+  unix.truncate(path:str[, length:int])
+      ├─→ true
+      └─→ nil, unix.Errno
+

+
+  unix.bind(fd:int[, ip:uint32, port:uint16])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Binds socket.
+
+    `ip` and `port` are in host endian order. For example, if you
+    wanted to listen on `1.2.3.4:31337` you could do any of these
+
+        unix.bind(sock, 0x01020304, 31337)
+        unix.bind(sock, ParseIp('1.2.3.4'), 31337)
+        unix.bind(sock, 1 << 24 | 0 << 16 | 0 << 8 | 1, 31337)
+
+    `ip` and `port` both default to zero. The meaning of bind(0, 0)
+    is to listen on all interfaces with a kernel-assigned ephemeral
+    port number, that can be retrieved and used as follows:
+
+        sock = assert(unix.socket())  -- create ipv4 tcp socket
+        assert(unix.bind(sock))       -- all interfaces ephemeral port
+        ip, port = assert(unix.getsockname(sock))
+        print("listening on ip", FormatIp(ip), "port", port)
+        assert(unix.listen(sock))

+           print("got client ip", FormatIp(clientip), "port", clientport)
+           unix.close(client)
+        end
+
+    Further note that calling `unix.bind(sock)` is equivalent to not
+    calling bind() at all, since the above behavior is the default.

+  unix.sigaction(sig:int[, handler:func|int[, flags:int[, mask:unix.Sigset]]])
+      ├─→ oldhandler:func|int, flags:int, mask:unix.Sigset
+      └─→ nil, unix.Errno
+
+    `sig` can be one of:
+
+    - `unix.SIGINT`
+    - `unix.SIGQUIT`
+    - `unix.SIGTERM`
+    - etc.
+
+    `handler` can be:
+
+    - Lua function
+    - `unix.SIG_IGN`
+    - `unix.SIG_DFL`
+
+    `flags` can have:
+
+    - `unix.SA_RESTART`: Enables BSD signal handling semantics. Normally
+      i/o entrypoints check for pending signals to deliver. If one gets
+      delivered during an i/o call, the normal behavior is to cancel the
+      i/o operation and return -1 with `EINTR` in errno. If you use the
+      `SA_RESTART` flag then that behavior changes, so that any function
+      that's been annotated with @restartable will not return `EINTR`
+      and will instead resume the i/o operation. This makes coding
+      easier but it can be an anti-pattern if not used carefully, since
+      poor usage can easily result in latency issues. It also requires
+      one to do more work in signal handlers, so special care needs to
+      be given to which C library functions are @asyncsignalsafe.
+
+    - `unix.SA_RESETHAND`: Causes signal handler to be single-shot. This
+      means that, upon entry of delivery to a signal handler, it's reset
+      to the `SIG_DFL` handler automatically. You may use the alias
+      `SA_ONESHOT` for this flag, which means the same thing.
+
+    - `unix.SA_NODEFER`: Disables the reentrancy safety check on your signal
+      handler. Normally that's a good thing, since for instance if your
+      `SIGSEGV` signal handler happens to segfault, you're going to want
+      your process to just crash rather than looping endlessly. But in
+      some cases it's desirable to use `SA_NODEFER` instead, such as at
+      times when you wish to `longjmp()` out of your signal handler and
+      back into your program. This is only safe to do across platforms
+      for non-crashing signals such as `SIGCHLD` and `SIGINT`. Crash
+      handlers should use Xed instead to recover execution, because on
+      Windows a `SIGSEGV` or `SIGTRAP` crash handler might happen on a
+      separate stack and/or a separate thread. You may use the alias
+      `SA_NOMASK` for this flag, which means the same thing.
+
+    - `unix.SA_NOCLDWAIT`: Changes `SIGCHLD` so the zombie is gone and
+      you can't call wait() anymore; similar but may still deliver the
+      SIGCHLD.
+
+    - `unix.SA_NOCLDSTOP`: Lets you set `SIGCHLD` handler that's only
+      notified on exit/termination and not notified on `SIGSTOP`,
+      `SIGTSTP`, `SIGTTIN`, `SIGTTOU`, or `SIGCONT`.
+
+    Example:
+
+        assert(unix.sigaction(unix.SIGUSR1, function(sig)
+           gotsigusr1 = true
+        end))
+        gotsigusr1 = false
+        assert(unix.raise(unix.SIGUSR1))
+        ok, err = unix.sigsuspend()
+        assert(err:errno == unix.EINTR)
+        if gotsigusr1
+           print('hooray the signal was delivered')
+        else
+           print('oh no some other signal was handled')
+        end
+
+    It's a good idea to not do too much work in a signal handler.
+
+  unix.sigsuspend([mask:Sigmask])
+      └─→ nil, unix.Errno
+
+    Waits for signal to be delivered.
+
+    The signal mask is temporarily replaced with `mask` during this
+    system call. `mask` specifies which signals should be blocked.
+
+  unix.setitimer(which[, intervalsec, intns, valuesec, valuens])
+      ├─→ intervalsec:int, intervalns:int, valuesec:int, valuens:int
+      └─→ nil, unix.Errno
+
+    Causes `SIGALRM` signals to be generated at some point(s) in the
+    future. The `which` parameter should be `ITIMER_REAL`.
+
+    Here's an example of how to create a 400 ms interval timer:
+
+        ticks = 0
+        assert(unix.sigaction(unix.SIGALRM, function(sig)
+           print('tick no. %d' % {ticks})
+           ticks = ticks + 1
+        end))
+        assert(unix.setitimer(unix.ITIMER_REAL, 0, 400e6, 0, 400e6))
+        while true do
+           unix.sigsuspend()
+        end
+
+    Here's how you'd do a single-shot timeout in 1 second:
+
+        unix.sigaction(unix.SIGALRM, MyOnSigAlrm, unix.SA_RESETHAND)
+        unix.setitimer(unix.ITIMER_REAL, 0, 0, 1, 0)
+
+  unix.strsignal(sig:int) → str
+
+    Turns platform-specific `sig` code into its symbolic name.
+
+    For example:
+
+        >: unix.strsignal(9)
+        "SIGKILL"
+        >: unix.strsignal(unix.SIGKILL)
+        "SIGKILL"
+
+    Please note that signal numbers are normally different across
+    supported platforms, and the constants should be preferred.
+
+  unix.setrlimit(resource:int, soft:int[, hard:int])
+      ├─→ true
+      └─→ nil, unix.Errno
+
+    Changes resource limit.
+
+    `resource` may be one of:
+
+    - `RLIMIT_AS` limits the size of the virtual address space. This
+      will work on all platforms. It's emulated on XNU and Windows which
+      means it won't propagate across execve() currently.
+
+    - `RLIMIT_CPU` causes `SIGXCPU` to be sent to the process when the
+      soft limit on CPU time is exceeded, and the process is destroyed
+      when the hard limit is exceeded. It works everywhere but Windows
+      where it should be possible to poll getrusage() with setitimer()
+
+    - `RLIMIT_FSIZE` causes `SIGXFSZ` to sent to the process when the
+      soft limit on file size is exceeded and the process is destroyed
+      when the hard limit is exceeded. It works everywhere but Windows
+
+    - `RLIMIT_NPROC` limits the number of simultaneous processes and it
+      should work on all platforms except Windows. Please be advised it
+      limits the process, with respect to the activities of the user id
+      as a whole.
+
+    - `RLIMIT_NOFILE` limits the number of open file descriptors and it
+      should work on all platforms except Windows (TODO)
+
+    If a limit isn't supported by the host platform, it'll be set to
+    127. On most platforms these limits are enforced by the kernel and
+    as such are inherited by subprocesses.
+
+    `hard` defaults to whatever was specified in `soft`.
+

+
+    `who` defaults to `RUSAGE_SELF` and can be any of:

+
+    This can be used to sandbox your redbean workers. It allows finer

+
+    By default exit and exit_group are always allowed. This is useful
+    for processes that perform pure computation and interface with the

+
+  unix.fstat(fd:int)
+      ├─→ unix.Stat
+      └─→ nil, unix.Errno
+
+    Gets information about opened file descriptor.
+

+
+    `flags` may have any of:
+
+    - `AT_SYMLINK_NOFOLLOW`: do not follow symbolic links.
+
+    `dirfd` defaults to to `unix.AT_FDCWD` and may optionally be set to
+    a directory file descriptor to which `path` is relative.
+
+    A common use for fstat() is getting the size of a file. For example:
+
+        fd = assert(unix.open("hello.txt", unix.O_RDONLY))
+        st = assert(unix.fstat(fd))

+
+    Closes directory stream object and associated its file descriptor.
+
+    This is called automatically by the garbage collector.
+

+
+  unix.Dir:read()
+      ├─→ name:str, kind:int, ino:int, off:int
+      └─→ nil
+
+    Reads entry from directory stream.
+
+    Returns `nil` if there are no more entries. Or error, `nil` will

+
+    `kind` can be any of:
+

+    - `DT_CHR`: file is a character device
+    - `DT_FIFO`: file is a named pipe
+    - `DT_SOCK`: file is a named socket
+    - `DT_UNKNOWN`
+
+    Note: This function also serves as the `__call` metamethod, so that
+    unix.Dir objects may be used as a for loop iterator.
+
+  unix.Dir:fd()
+      ├─→ fd:int

+
+    On Windows NT this is collected from GetProcessTimes().
+
+  unix.Rusage:maxrss()

+
+    If you chart memory usage over the lifetime of your process, then
+    this would be the space filled in beneath the chart. The frequency
+    of kernel scheduling is defined as unix.CLK_TCK.  Each time a tick
+    happens, the kernel samples your process's memory usage, by adding

+
+    Currently only available on FreeBSD and NetBSD.
+
+  unix.Rusage:minflt()
+      └─→ count:int
+
+    Returns number of minor page faults.
+
+    This number indicates how many times redbean was preempted by the

+
+    On Windows NT this is NtProcessMemoryCountersEx::PageFaultCount.
+
+  unix.Rusage:nswap()
+      └─→ count:int
+
+    Returns number of swap operations.
+
+    Operating systems like to reserve hard disk space to back their RAM
+    guarantees, like using a gold standard for fiat currency. When your
+    system is under heavy memory load, swap operations may happen while
+    redbean is working. This number keeps track of them.
+
+    Not available on Linux, Windows NT.
+
+  unix.Rusage:inblock()
+      └─→ count:int

+    Returns count of ipc messages sent.
+
+    Not available on Linux, Windows NT.
+
+  unix.Rusage:msgrcv()
+      └─→ count:int
+
+    Returns count of ipc messages received.
+
+    Not available on Linux, Windows NT.
+
+  unix.Rusage:nsignals()
+      └─→ count:int
+
+    Returns number of signals received.
+
+    Not available on Linux.
+
+  unix.Rusage:nvcsw()
+      └─→ count:int
+
+    Returns number of voluntary context switches.
+
+    This number is a good thing. It means your redbean finished its work
+    quickly enough within a time slice that it was able to give back the
+    remaining time to the system.
+
+  unix.Rusage:nivcsw()
+      └─→ count:int
+
+    Returns number of non-consensual context switches.
+
+    This number is a bad thing. It means your redbean was preempted by a
+    higher priority process after failing to finish its work, within the
+    allotted time slice.

+
+ UNIX STAT OBJECT
+
+  unix.Stat objects are created by stat() or fstat(). The following
+  accessor methods are available.
+
+  unix.Stat:size()
+      └─→ bytes:int
+
+    Size of file in bytes.
+
+  unix.Stat:mode()
+      └─→ mode:int
+
+   Contains file type and permissions.
+
+   For example, `0010644` is what you might see for a file and
+   `0040755` is what you might see for a directory.
+
+   To determine the file type:
+
+     - `(st:mode() & 0170000) == 0010000` means fifo or pipe
+     - `(st:mode() & 0170000) == 0020000` means character device
+     - `(st:mode() & 0170000) == 0040000` means directory
+     - `(st:mode() & 0170000) == 0060000` means block device
+     - `(st:mode() & 0170000) == 0100000` means regular file
+     - `(st:mode() & 0170000) == 0120000` means symbolic link
+     - `(st:mode() & 0170000) == 0140000` means socket
+
+  unix.Stat:uid()
+      └─→ uid:int
+
+    User ID of file owner.
+
+  unix.Stat:gid()
+      └─→ gid:int
+
+    Group ID of file owner.
+
+  unix.Stat:birthtim()
+      └─→ unixts:int, nanos:int
+
+    File birth time.
+
+    This field should be accurate on Apple, Windows, and BSDs. On Linux
+    this is the mimimum of atim/mtim/ctim. On Windows NT nanos is only
+    accurate to hectonanoseconds.
+
+    Here's an example of how you might print a file timestamp:
+
+        st = assert(unix.stat('/etc/passwd'))
+        unixts, nanos = st:birthtim()
+        year,mon,mday,hour,min,sec,gmtoffsec = unix.localtime(unixts)
+        Write('%.4d-%.2d-%.2dT%.2d:%.2d:%.2d.%.9d%+.2d%.2d % {
+                 year, mon, mday, hour, min, sec, nanos,
+                 gmtoffsec / (60 * 60), math.abs(gmtoffsec) % 60})
+
+  unix.Stat:mtim()
+      └─→ unixts:int, nanos:int
+
+    Last modified time.
+
+  unix.Stat:atim()
+      └─→ unixts:int, nanos:int
+
+    Last access time.
+
+    Please note that file systems are sometimes mounted with `noatime`
+    out of concern for i/o performance. Linux also provides `O_NOATIME`
+    as an option for open().
+
+    On Windows NT this is the same as birth time.
+
+  unix.Stat:ctim()
+      └─→ unixts:int, nanos:int
+
+    Complicated time.
+
+    Means time file status was last changed on UNIX.
+
+    On Windows NT this is the same as birth time.
+
+  unix.Stat:blocks()
+      └─→ count512:int
+
+    Number of 512-byte blocks used by storage medium.
+
+    This provides some indication of how much physical storage a file
+    actually consumes. For example, for small file systems, your system
+    might report this number as being 8, which means 4096 bytes.
+
+    On Windows NT, if `O_COMPRESSED` is used for a file, then this
+    number will reflect the size *after* compression. you can use:
+
+        st = assert(unix.stat("moby.txt"))
+        print('file size is %d bytes' % {st:size()})
+        print('file takes up %d bytes of space' % {st:blocks() * 512})
+        if GetHostOs() == 'WINDOWS' and st:flags() & 0x800 then
+           print('thanks to file system compression')
+        end
+
+    To tell whether or not compression is being used on a file,
+
+  unix.Stat:blksize()
+      └─→ bytes:int
+
+    Block size that underlying device uses.
+
+    This field might be of assistance in computing optimal i/o sizes.
+
+    Please note this field has no relationship to blocks, as the latter
+    is fixed at a 512 byte size.
+
+  unix.Stat:ino()
+      └─→ inode:int
+
+    Inode number.
+
+    This can be used to detect some other process used rename() to swap
+    out a file underneath you, so you can do a refresh. redbean does it
+    during each main process heartbeat for its own use cases.
+
+    On Windows NT this is set to NtByHandleFileInformation::FileIndex.
+
+  unix.Stat:dev()
+      └─→ dev:int
+
+    ID of device containing file.
+
+    On Windows NT this is set to
+    NtByHandleFileInformation::VolumeSerialNumber.
+
+  unix.Stat:rdev()
+      └─→ rdev:int
+
+    Information about device type.
+
+    This value may be set to 0 or -1 for files that aren't devices,
+    depending on the operating system. unix.major() and unix.minor()
+    may be used to extract the device numbers.
+
+

+
+ UNIX SIGSET OBJECT
+
+  The unix.Sigset class defines a mutable bitset that may currently
+  contain 128 entries. See `unix.NSIG` to find out how many signals
+  your operating system actually supports.
+
+  unix.Sigset(sig:int, ...)
+      └─→ unix.Sigset
+
+    Constructs new signal bitset object.
+
+  unix.Sigset:add(sig:int)
+
+    Adds signal to bitset.
+
+  unix.Sigset:remove(sig:int)
+
+    Removes signal from bitset.
+
+  unix.Sigset:fill()
+
+    Sets all bits in signal bitset to true.
+
+  unix.Sigset:clear()
+
+    Sets all bits in signal bitset to false.
+
+  unix.Sigset:contains(sig:int)
+      └─→ bool
+
+    Returns true if `sig` is member of signal bitset.
+
+  unix.Sigset:__repr()
+  unix.Sigset:__tostring()
+
+    Returns Lua code string that recreates object.

+
+ UNIX ERRNO OBJECT
+
+  This object is returned by system calls that fail. We prefer returning
+  an object because for many system calls, an error is part their normal
+  operation. For example, it's often desirable to use the errno() method
+  when performing a read() to check for EINTR.
+
+  unix.Errno:errno()
+      └─→ errno:int
+
+    Returns error magic number.
+
+    The error number is always different for different platforms. On
+    UNIX systems, error numbers occupy the range [1,127] in practice.
+    The System V ABI reserves numbers as high as 4095. On Windows NT,
+    error numbers can go up to 65535.
+
+  unix.Errno:winerr()
+      └─→ errno:int
+
+    Returns Windows error number.
+
+    On UNIX systems this is always 0. On Windows NT this will normally
+    be the same as errno(). Because Windows defines so many error codes,
+    there's oftentimes a multimapping between its error codes and System
+    Five. In those cases, this value reflect the GetLastError() result
+    at the time the error occurred.
+
+  unix.Errno:name()
+      └─→ symbol:str
+
+    Returns string of symbolic name of System Five error code.
+
+    For example, this might return `"EINTR"`.
+
+  unix.Errno:call()
+      └─→ symbol:str
+
+    Returns name of system call that failed.
+
+    For example, this might return `"read"` if read() was what failed.
+
+  unix.Errno:doc()
+      └─→ symbol:str
+
+    Returns English string describing System Five error code.
+
+    For example, this might return `"Interrupted system call"`.
+
+  unix.Errno:__tostring()
+      └─→ str
+
+    Returns verbose string describing error.
+
+    Different information components are delimited by slash.
+
+    For example, this might return `"EINTR/4/Interrupted system call"`.
+
+    On Windows NT this will include additional information about the
+    Windows error (including FormatMessage() output) if the WIN32 error
+    differs from the System Five error code.

+ UNIX ERROR MAGNUMS
+
+  unix.EINVAL
+    Invalid argument.
+
+    Raised by [pretty much everything].

+    readlink, rename, rmdir, stat, swapon, symlink, truncate, unlink,
+    utime, utimensat.
+
+  unix.ENOTDIR
+    Not a directory. This means that a directory component in a supplied
+    path *existed* but wasn't a directory. For example, if you try to
+    `open("foo/bar")` and `foo` is a regular file, then `ENOTDIR` will
+    be returned.
+
+    Raised by open, access, chdir, chroot, execve, link, mkdir, mknod,

+    needs polling, etc.).
+
+    Raised by accept, connect, fcntl, fork, getrandom, mincore, mlock,

+    sigwaitinfo, splice, tee, timer_create, timerfd_create, tkill,
+    write,
+
+  unix.EPIPE
+    Broken pipe. Returned by write, send. This happens when you try
+    to write data to a subprocess via a pipe but the reader end has
+    already closed, possibly because the process died. Normally i/o
+    routines only return this if `SIGPIPE` doesn't kill the process.
+    Unlike default UNIX programs, redbean currently ignores `SIGPIPE` by
+    default, so this error code is a distinct possibility when pipes or
+    sockets are being used.
+
+  unix.ENAMETOOLONG
+    Filename too long. Cosmopolitan Libc currently defines `PATH_MAX` as
+    1024 characters. On UNIX that limit should only apply to system call
+    wrappers like realpath. On Windows NT it's observed by all system
+    calls that accept a pathname.

+
+ UNIX MISCELLANEOUS MAGNUMS
+
+  unix.ARG_MAX
+
+    Returns maximum length of arguments for new processes.
+
+    This is the character limit when calling execve(). It's the sum of
+    the lengths of `argv` and `envp` including any nul terminators and
+    pointer arrays. For example to see how much your shell `envp` uses
+
+        $ echo $(($(env | wc -c) + 1 + ($(env | wc -l) + 1) * 8))
+        758
+
+    POSIX mandates this be 4096 or higher. On Linux this it's 128*1024.
+    On Windows NT it's 32767*2 because CreateProcess lpCommandLine and
+    environment block are separately constrained to 32,767 characters.
+    Most other systems define this limit much higher.
+
+  unix.BUFSIZ
+
+    Returns default buffer size.
+
+    The UNIX module does not perform any buffering between calls.
+
+    Each time a read or write is performed via the UNIX API your redbean
+    will allocate a buffer of this size by default. This current default
+    would be 4096 across platforms.
+
+  unix.CLK_TCK
+
+    Returns the scheduler frequency.
+
+    This is granularity at which the kernel does work. For example, the
+    Linux kernel normally operates at 100hz so its CLK_TCK will be 100.
+
+    This value is useful for making sense out of unix.Rusage data.
+
+  unix.PIPE_BUF
+
+    Returns maximum size at which pipe i/o is guaranteed atomic.
+
+    POSIX requires this be at least 512. Linux is more generous and
+    allows 4096. On Windows NT this is currently 4096, and it's the
+    parameter redbean passes to CreateNamedPipe().
+
+  unix.PATH_MAX
+
+    Returns maximum length of file path.
+
+    This applies to a complete path being passed to system calls.
+
+    POSIX.1 XSI requires this be at least 1024 so that's what most
+    platforms support. On Windows NT, the limit is technically 260
+    characters. Your redbean works around that by prefixing `//?/`
+    to your paths as needed. On Linux this limit will be 4096, but
+    that won't be the case for functions such as realpath that are
+    implemented at the C library level; however such functions are
+    the exception rather than the norm, and report enametoolong(),
+    when exceeding the libc limit.
+
+  unix.NAME_MAX
+
+    Returns maximum length of file path component.
+
+    POSIX requires this be at least 14. Most operating systems define it
+    as 255. It's a good idea to not exceed 253 since that's the limit on
+    DNS labels.
+
+  unix.NSIG
+
+    Returns maximum number of signals supported by underlying system.
+
+    The limit for unix.Sigset is 128 to support FreeBSD, but most
+    operating systems define this much lower, like 32. This constant
+    reflects the value chosen by the underlying operating system.

+DESCRIPTION
+
+  plinko is a simple lisp interpreter that takes advantage of advanced
+  operating system features irrespective of their practicality such as
+  using the nsa instruction popcount for mark sweep garbage collection
+  overcommit memory, segment registers, and other dirty hacks that the
+  popular interpreters cannot do; this lets plinko gain a considerable
+  performance edge while retaining an event greater edge in simplicity
+
+  We hope you find these sources informative, eductional, and possibly
+  useful too. Lisp source code, written in its dialect is included too
+  under //tool/plinko/lib and unit tests which clarify their usage can
+  be found in //test/tool/plinko.

+/**
+ * Performs lookup of binding.
+ *
+ * We perform lookups into an association list, e.g.
+ *
+ *       ┌───┬───┐ ┌───┬───┐ ┌───┬───┐
+ *       │ 𝑘₀│ 𝑣₀│ │ 𝑘₁│ 𝑣₁│ │ 𝑘₂│ 𝑣₂│
+ *       └─┬─┴───┘ └─┬─┴───┘ └─┬─┴───┘
+ *       ┌─│─┬───┐ ┌─│─┬───┐ ┌─│─┬───┐
+ *     𝑎=│ ┴ │ ├───┤ ┴ │ ├───┤ ┴ │ 0 │
+ *       └───┴───┘ └───┴───┘ └───┴───┘
+ *
+ * For example, if 𝑘₁ is queried then we return:
+ *
+ *     ┌───┬───┐
+ *     │ 𝑘₁│ 𝑣₁│
+ *     └───┴───┘
+ *
+ * However there's a twist: the association is allowed to turn into a
+ * red-black tree. That would look like this:
+ *
+ *       ┌───┬───┐ ┌───┬───┐
+ *       │ 𝑘₀│ 𝑣₀│ │ 𝑘₁│ 𝑣₁│
+ *       └─┬─┴───┘ └─┬─┴───┘
+ *       ┌─│─┬───┐ ┌─│─┬───┐ ┌───┬───┐
+ *     𝑎=│ ┴ │ ├───┤ ┴ │ ├───│ ┬ │ 𝑐 │
+ *       └───┴───┘ └───┴───┘ └─│─┴───┘
+ *                           ┌─┴─┬───┐

+ *                           └─│─┴─│─┘
+ *                      ┌───┬──┴┐ ┌┴──┬───┐

+ *                      └───┴───┘ └───┴───┘
+ *
+ * We're able to tell a tree node apart from an association list node
+ * because we make the assumption that 𝑘ᵢ is an atom. On the other hand
+ * 𝑣ᵢ can be anything.

-  Justine Tunney <jtunney@gmail.com>
-
-DESCRIPTION
-
-  This program demonstrates a straightforward technique for displaying
-  PNG/GIF/JPG/etc. files from the command line. This program supports
-  xterm256 and 24-bit color w/ UNICODE half blocks. For example:
-
-    apt install build-essential imagemagick
-    ./printimage.c lemur.png
-
-NOTES
-
-  More advanced techniques exist for (1) gaining finer detail, as well
-  as (2) reducing the number of bytes emitted; this program is here to
-  get you started. */
