3e19b96ab8 Add more POSIX function stubs
Cosmopolitan currently doesn't support threads and it doesn't do
anything fancy in longjmp/setjmp so this change was simple to do

- localeconv
- _setjmp (same as setjmp)
- _longjmp (same as longjmp)
- strcoll (same as strcmp)
- flockfile (does nothing)
- funlockfile (does nothing)
- ftrylockfile (does nothing)

7e4021bf82 Put Redbean in uniprocess mode on NT temporarily
The Windows fork() polyfill (which we implement using pure WIN32)
appears to be acting strangely. It's possible a regression was
introduced by recent changes that our tests didn't catch.

This change is workaround so we can upload a new working binary release
to the Redbean website until we can fully fix the problem.

94afa982c3 Fix zip executables on MacOS
Here's why we got those `Killed: 11` failures on MacOS after modifying
the contentns of the redbean.com executable. If you were inserting a
small file, such as a HelloWorld.html file, then InfoZIP might have
decreased the size of the executable to less than what the Mach-O
section had been expecting.

That's because when zipobj.com put things like time zone data in the
executable, it aligned each zip file entry on a 64-byte boundary, simply
for the sake of readability in binary dumps. But when InfoZIP edited the
file it would rewrite every entry using ZIP's usual 2-byte alignment.
Thus causing shrinkage.

The solution was to reconfigure the linker script so that zip file bits
that get put into the executable at link-time, such as timezone data,
aren't officially part of the executable image, i.e. we don't want the
operating system to load that part.

The original decision to put the linked zip files into the .data section
was mostly made so that when the executable was run in its .com.dbg form
it would still have the zip entries be accessible, even though there was
tons of GNU debug data following the central directory. We're not going
to be able to do that. The .com executable should be the canonical
executable. We have really good tools for automatically attaching and
configuring GDB correctly with debug symbols even when the .com is run.
We'll have to rely on those in cases where zip embedding is used.

cc56038b05 Fix memzoom on Windows
Right now we can't call poll() on file and fifos on Windows. So we work
around that by simply blocking on keyboard input. This is OK because on
Windows we can't use /proc/*/mem for realtime monitoring, so there's no
reason not to block.

This regression snuck in at some point. It resulted in the program

91f4167a45 Add root redirect for redbean webserver
We have a webserver demo:

    make -j8 o//tool/net/redbean.com
    o/tool/net/redbean.com -v

It's been a little bit confusing that until now you had to visit the
following URL in order to see the default web page:

    http://127.0.0.1:8080/tool/net/redbean.html

The following URLs will now redirect to the above page, but only if
nothing's been defined for those paths and they would otherwise result
in a 404 response:

    http://127.0.0.1:8080/
    http://127.0.0.1:8080/index.html

edd9297eba Support malloc() on bare metal
Your Actually Portable Executables now contains a simple virtual memory
that works similarly to the Linux Kernel in the sense that it maps your
physical memory to negative addresses. This is needed to support mmap()
and malloc(). This functionality has zero code size impact. For example
the MODE=tiny LIFE.COM executable is still only 12KB in size.

The APE bootloader code has also been simplified to improve readibility
and further elevate the elegance by which we're able to support so many
platforms thereby enhancing verifiability so that we may engender trust
in this bootloading process.

e85aeda4ba Fix some more build issues (#43)
We're now scrubbing environment variables in compile.com since gnu make
was not behaving as expected. It also appears there was a regression in
recent revisions that caused ASAN to be turned off for most binaries in
dbg mode, which has now been fixed. Cosmopolitan is fully ASAN hardened
down to the lowest level libraries and it doesn't need any interceptors

e75ffde09e Get codebase completely working with LLVM
You can now build Cosmopolitan with Clang:

    make -j8 MODE=llvm
    o/llvm/examples/hello.com

The assembler and linker code is now friendly to LLVM too.
So it's not needed to configure Clang to use binutils under
the hood. If you love LLVM then you can now use pure LLVM.

9f149e1de3 Elevate .text.syscall to .privileged
It turns out adding OpenBSD msyscall() origin verification broke the
--ftrace flag. The executable needs to issue raw syscalls while it's
rewriting itself. So they need to be in the same section, and that's
just plain simpler too.

you can build objects that link against Cosmopolitan using any compiler
and you can furthermore use tools like IntelliSense that can't even GNU

4e56d89dcd Eliminate some flakes
- Get ASAN working on Windows.

- Deleting directories and then recreating them with the same name in a
  short period of time appears to be a no-no on Windows.

- There's no reason to call FlushFileBuffers on close() for pipes, and
  it's harmful since it might block indefinitely for no good reason.
