Update.
1998-07-27 17:42 Ulrich Drepper <drepper@cygnus.com>
* nss/nss_files/files-parse.c (INT_FIELD): Use strtoul instead of
strtol.
(INT_FIELD_MAYBE_NULL): Likewise.
* posix/globtest.c: Rewrite for extended test suite.
* posix/globtest.sh: More tests.
Patch by Brian Wellington <bwelling@anomaly.munge.com>.
* stdlib/strtol.c: Don't redefine LONG_MAX, LONG_MIN, and ULONG_MAX.
Use new macro.
* sysdeps/generic/readv.c: Correct return type.
* sysdeps/generic/writev.c: Likewise.
1998-07-24 Gordon Matzigkeit <gord@fig.org>
* argp/argp-help.c (_GNU_SOURCE): Define, to suck in
program_invocation_name when compiling outside of glibc.
1998-07-26 Philip Blundell <philb@gnu.org>
* sysdeps/unix/sysv/linux/arm/siglist.c: New file; ARM tools don't
like `@' in .type directives.
* sysdeps/libm-ieee754/e_expf.c (__ieee754_expf): Check whether
FE_TONEAREST exists for this platform before using it.
* sysdeps/libm-ieee754/e_exp.c (__ieee754_exp): Likewise.
* sysdeps/arm/dl-machine.h (elf_machine_rel): Delete redundant
debugging code. Correct handling of PC24 relocs.
* elf/Makefile (ld-map): Only define if versioning is in use.
* sysdeps/arm/fpu_control.h: Move to ...
* sysdeps/arm/fpu/fpu_control.h: ... here.
* sysdeps/generic/fpu_control.h: Made usable as a dummy
implementation.
* sysdeps/unix/sysv/linux/arm/brk.c: New file.
* sysdeps/arm/machine-gmon.h: Improved profiling for ARM.
* sysdeps/arm/sysdep.h (CALL_MCOUNT): Replace stub with real
implementation.
* sysdeps/unix/sysv/linux/arm/clone.S: Likewise.
Based on patch from Scott Bambrough and Pat Beirne.
* shlib-versions: Add appropriate definitions for ARM machines.
* README.template: Mention that Linux/ARM with ELF works now.
1998-07-18 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* Makerules: Generate compilation rules for all object suffixes,
not only those currently selected, for sources in the current or
object directory.
1998-07-24 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* posix/fnmatch.c (fnmatch): Allow `/' in character class. Don't
match `/' in filename by a character class if requested.
* posix/testfnm.c: Rewritten.
* posix/testfnm.args: Removed.
1998-07-25 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* posix/annexc.c (limits_syms): Add missing symbols.
(stdarg_syms): Move va_list to `maybe' list.
(stdio_syms): Add FOPEN_MAX.
