glibc/catgets/catgets.c
Ulrich Drepper b6aa34eb72 Update.
* locale/loadlocale.c (_nl_load_locale): Optimize a bit.  Pretty
	print.  Add checks for _POSIX_MMAPPED_FILES where necessary.
	(_nl_unload_locale): If locale data was mmapped use munmap.

2000-01-29  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/i386/sys/io.h: Add missing ints, use
	_EXTERN_INLINE, compile inline assembler functions only with gcc.

2000-01-29  Ulrich Drepper  <drepper@redhat.com>

	* catgets/catgets.c (catopen): Handle NL_CAT_LOCALE correctly.
	* catgets/gencat.c (read_input_file): Remove messages correctly.
	* catgets/open_catalog.c (__open_catalog): Handle trailing colons and
	adjacent colons correctly.  Correct loops to read territory and
	and codeset part.
	Patches by Geoff Clare <gwc@unisoft.com> (PR libc/1559).

	* rt/aio_misc.c (get_elem): Assign pointer to new row to correct
	pool entry.
	Patch by Jens Moeller <jens.moeller@waii.com> (PR libc/1558).

2000-01-28  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/arm/Versions: Export the new *rlimit
	interface with symbol version GLIBC_2.2.
	* sysdeps/unix/sysv/linux/i386/Versions: Likewise.
	* sysdeps/unix/sysv/linux/i386/getrlimit.c: Likewise.
	* sysdeps/unix/sysv/linux/i386/getrlimit64.c: Likewise.
	* sysdeps/unix/sysv/linux/i386/setrlimit.c: Likewise.

2000-01-27  Scott Bambrough  <scottb@netwinder.org>

	* sysdeps/unix/sysv/linux/arm/Makefile: Backout rlimit changes for
	resource directory.
	* sysdeps/unix/sysv/linux/arm/syscalls.list: Backout changes for
	versioning setrlimit and getrlimit.

2000-01-27  Andreas Jaeger  <aj@suse.de>

	* sysdeps/powerpc/fpu/libm-ulps: Renamed to ...
	* sysdeps/powerpc/fpu/libm-test-ulps: ...this.

2000-01-27  Ruediger Oertel  <ro@suse.de>

	* sysdeps/unix/sysv/linux/i386/sys/io.h: Change "::" to ": :" for g++.
