* 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.

/* This header file provides the reentrancy. */
|

|
/* The reentrant system calls here serve two purposes:
|
|
|
|
1) Provide reentrant versions of the system calls the ANSI C library
|
|
requires.
|
|
2) Provide these system calls in a namespace clean way.
|
|
|
|
It is intended that *all* system calls that the ANSI C library needs
|
|
be declared here. It documents them all in one place. All library access
|
|
to the system is via some form of these functions.
|
|
|
|
There are three ways a target may provide the needed syscalls.
|
|
|
|
1) Define the reentrant versions of the syscalls directly.
|
|
(eg: _open_r, _close_r, etc.). Please keep the namespace clean.
|
|
When you do this, set "syscall_dir" to "syscalls" in configure.in,
|
|
and add -DREENTRANT_SYSCALLS_PROVIDED to target_cflags in configure.in.
|
|
|
|
2) Define namespace clean versions of the system calls by prefixing
|
|
them with '_' (eg: _open, _close, etc.). Technically, there won't be
|
|
true reentrancy at the syscall level, but the library will be namespace
|
|
clean.
|
|
When you do this, set "syscall_dir" to "syscalls" in configure.in.
|
|
|
|
3) Define or otherwise provide the regular versions of the syscalls
|
|
(eg: open, close, etc.). The library won't be reentrant nor namespace
|
|
clean, but at least it will work.
|
|
When you do this, add -DMISSING_SYSCALL_NAMES to target_cflags in
|
|
configure.in.
|
|
|
|
Stubs of the reentrant versions of the syscalls exist in the libc/reent
|
|
source directory and are used if REENTRANT_SYSCALLS_PROVIDED isn't defined.
|
|
They use the native system calls: _open, _close, etc. if they're available
|
|
(MISSING_SYSCALL_NAMES is *not* defined), otherwise open, close, etc.
|
|
(MISSING_SYSCALL_NAMES *is* defined). */
|
|
|
|
/* WARNING: All identifiers here must begin with an underscore. This file is
|
|
included by stdio.h and others and we therefore must only use identifiers
|
|
in the namespace allotted to us. */
