2002-08-17 Jeff Johnston <jjohnstn@redhat.com> * Makefile.am: Move cmath stuff into libc/sys/linux. * Makefile.in: Regenerated. * configure.host: Default -DMB_CAPABLE for x86-linux. * libc/include/reent.h: Define _sbrk to take signed int argument. * libc/include/sys/unistd.h: Ditto for _sbrk_r and sbrk. * libc/locale/locale.c[MB_CAPABLE]: Add LC_MESSAGES support and make locale name checking more efficient. Also allow "C-ISO-8859-1" locale for LC_CTYPE and LC_MESSAGES. * libc/reent/sbrkr.c: Change prototype to take ptrdiff_t. * libc/sys/linux/brk.c: Change sbrk prototype. * libc/sys/linux/include/time.h: Remove Cygwin stuff and include <sys/features.h>. (CLOCK_THREAD_CPUTIME): Renamed to CLOCK_THREAD_CPUTIME_ID. (CLOCK_PROCESS_CPUTIME): Renamed to CLOCK_PROCESS_CPUTIME_ID. * libc/sys/linux/sys/cdefs.h: Replace with glibc sys/cdefs.h with a few local additions. * libc/sys/linux/sys/features.h: New file. * libc/sys/linux/sys/unistd.h: Change _sbrk_r and sbrk prototypes to take signed argument. * libc/syscalls/syssbrk.c: Change sbrk, _sbrk_r, and _sbrk prototypes to take signed size argument. 2002-08-17 05:19:18 +00:00			`extern void _sbrk_r (struct _reent , ptrdiff_t);`
