Use gnulib-tool to create gnulib source files.
* Add gnulib files generated by gnulib-tool in build-aux, m4 and
grub-core/gnulib directories
* .bzignore: Add **/.deps and autogenerated gnulib files
* configure.ac: Assign auxiliary directory to build-aux, add invocation
of gnulib macros, add grub-core/gnulib/Makefile
* Makefile.am: Add gnulib directory in SUBDIRS (removing unnecessary .),
include m4 directory to aclocal.
* Makefile.util.def: Remove direct compilation of gnulib source files
and use the new grub-core/gnulib/libgnu.a.
* build-aux/config.rpath: move config.rpath from top directory to
build-aux
* conf/Makefile.common: Remove the macro _GL_UNUSED already defined
in gnulib headers
* conf/Makefile.extra-dist: Add m4/gnulib-cache.m4
* grub-core/Makefile.core.def: Remove unnecessary extra_dist
* grub-core/lib/posix_wrap/localcharset.h (locale_charset): Update
header.
* grub-core/lib/posix_wrap/langinfo.h (nl_langinfo): Return static
string.

/* ISO C 99 <stdbool.h> for platforms that lack it. */
|
||||
|
||||
/* Usage suggestions:
|
||||
|
||||
Programs that use <stdbool.h> should be aware of some limitations
|
||||
and standards compliance issues.
|
||||
|
||||
Standards compliance:
|
||||
|
||||
- <stdbool.h> must be #included before 'bool', 'false', 'true'
|
||||
can be used.
|
||||
|
||||
- You cannot assume that sizeof (bool) == 1.
|
||||
|
||||
- Programs should not undefine the macros bool, true, and false,
|
||||
as C99 lists that as an "obsolescent feature".
|
||||
|
||||
Limitations of this substitute, when used in a C89 environment:
|
||||
|
||||
- <stdbool.h> must be #included before the '_Bool' type can be used.
|
||||
|
||||
- You cannot assume that _Bool is a typedef; it might be a macro.
|
||||
|
||||
- Bit-fields of type 'bool' are not supported. Portable code
|
||||
should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
|
||||
|
||||
- In C99, casts and automatic conversions to '_Bool' or 'bool' are
|
||||
performed in such a way that every nonzero value gets converted
|
||||
to 'true', and zero gets converted to 'false'. This doesn't work
|
||||
with this substitute. With this substitute, only the values 0 and 1
|
||||
give the expected result when converted to _Bool' or 'bool'.
|
||||
|
||||
- C99 allows the use of (_Bool)0.0 in constant expressions, but
|
||||
this substitute cannot always provide this property.
|
||||
|
||||
Also, it is suggested that programs use 'bool' rather than '_Bool';
|
||||
this isn't required, but 'bool' is more common. */

|

It is tempting to write

typedef enum { false = 0, true = 1 } _Bool;
|
||||
so that gdb prints values of type 'bool' symbolically. But if we do
|
||||
this, values of type '_Bool' may promote to 'int' or 'unsigned int'
|
||||
(see ISO C 99 6.7.2.2.(4)); however, '_Bool' must promote to 'int'
|
||||
(see ISO C 99 6.3.1.1.(2)). So we add a negative value to the
|

enum; this ensures that '_Bool' promotes to 'int'. */

|

Use of an enum type, with IRIX cc, leads to a stupid
|

"warning(1185): enumerated type mixed with another type".

Even the existence of an enum type, without a typedef,
|

"Invalid enumerator. (badenum)" with HP-UX cc on Tru64.
