Rich Felker 4eb4844b31 fix issues with wait constants in stdlib.h
the W* namespace is not reserved, so the nonstandard ones must be
moved under extension features. also WNOHANG and WUNTRACED were
missing.

Rich Felker c1a9658bd1 default features: make musl usable without feature test macros
the old behavior of exposing nothing except plain ISO C can be
obtained by defining __STRICT_ANSI__ or using a compiler option (such
as -std=c99) that predefines it. the new default featureset is POSIX
with XSI plus _BSD_SOURCE. any explicit feature test macros will
inhibit the default.

installation docs have also been updated to reflect this change.

Rich Felker c8ea985748 add _Noreturn function attribute, with fallback for pre-C11 GNUC 2012-09-06 23:12:27 -04:00
Rich Felker 400c5e5c83 use restrict everywhere it's required by c99 and/or posix 2008
to deal with the fact that the public headers may be used with pre-c99
compilers, __restrict is used in place of restrict, and defined
appropriately for any supported compiler. we also avoid the form
[restrict] since older versions of gcc rejected it due to a bug in the
original c99 standard, and instead use the form *restrict.

Rich Felker 9bff7c133e implement "low hanging fruit" from C11
based on Gregor's patch sent to the list. includes:
- stdalign.h
- removing gets in C11 mode
- adding aligned_alloc and adjusting other functions to use it
- adding 'x' flag to fopen for exclusive mode

Rich Felker 3b94daba71 _GNU_SOURCE is supposed to imply _LARGEFILE64_SOURCE
this is ugly and stupid, but now that the *64 symbol names exist, a
lot of broken GNU software detects them in configure, then either
breaks during build due to missing off64_t definition, or attempts to
compile without function declarations/prototypes. "fixing" it here is
easier than telling everyone to add yet another feature test macro to
their builds.

Rich Felker 419ae6d5c9 support _BSD_SOURCE feature test macro
patch by Isaac Dunham. matched closely (maybe not exact) to glibc's
idea of what _BSD_SOURCE should make visible.

Rich Felker 2dd8d5e1b8 add support for ugly *64 functions with _LARGEFILE64_SOURCE
musl does not support legacy 32-bit-off_t whatsoever. off_t is always
64 bit, and correct programs that use off_t and the standard functions
will just work out of the box. (on glibc, they would require
-D_FILE_OFFSET_BITS=64 to work.) however, some programs instead define
_LARGEFILE64_SOURCE and use alternate versions of all the standard
types and functions with "64" appended to their names.

we do not want code to actually get linked against these functions
(it's ugly and inconsistent), so macros are used instead of prototypes
with weak aliases in the library itself. eventually the weak aliases
may be added at the library level for the sake of using code that was
originally built against glibc, but the macros will still be the
desired solution in the headers.

Rich Felker 3be616c1df fix alloca issue in stdlib.h too
I forgot _GNU_SOURCE also has it declared here...
2012-04-09 16:22:05 -04:00
Rich Felker f4ad36c4bf add deprecated (removed from posix) [efg]cvt() functions
these have not been heavily tested, but they should work as described
in the old standards. probably broken for non-finite values...

Rich Felker d4045a1683 declare alloca in stdlib.h when _GNU_SOURCE is defined 2011-09-11 22:43:57 -04:00
Rich Felker 4b5f054098 move wait.h macros out of bits. they do not vary. 2011-04-21 14:27:28 -04:00
Rich Felker 750b738e53 add ptsname_r (nonstandard) and split ptsname (standard) to separate file
this eliminates the ugly static buffer in programs that use ptsname_r.
