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.
