update from main archive 970202cvs/libc-970203

1997-02-03 02:33  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-deps.c (_dl_map_object_deps): Handle multiple AUXILIARY
	entries.  This is still no complete implementation since AUXILIARY
	entries in other shared objects are not yet handled.

	* libio/libio.h (_IO_cookie_io_functions_t): Move to C++ protected
	place.

	* po/es.po: Update.
	* po/fr.po: Update.
	* po/nl.po: Update.

	* time/Makefile: Better cross-compile support.  Avoid test which
	cannot be run.
	(CFLAGS-tzset.c): New variable.  Overwrite TZDEFAULT value from
	tzfile.h file.
	* time/tzfile.c (__tzfile_read): Allow TZDEFAULT start with '/' even
	in SUID programs.
	* time/tzset.c (__tzset_internal): If TZ envvar is not set use same
	default values as in tzfile.c.

	* elf/dynamic-link.h (elf_get_dynamic_info): Recognize versioning
	tags.
	* elf/link.h: Likewise.
	* elf/elf.h: Add tag definitions and data structures for versioning.

1997-02-03 02:17  Ulrich Drepper  <drepper@cygnus.com>

	* nis/rpcsvc/yp.x (struct ypresp_key_val): There is not stupid
	"Sun bug".  This is the order of elements also used by 4.4BSD.
	* nis/rpcsvc/yp.h: Likewise.
	Reported by HJ Lu.

1997-02-02 12:13  H.J. Lu  <hjl@gnu.ai.mit.edu>

	* sunrpc/Makefile ($(objpfx)x%.h, $(objpfx)x%.c): Add "@:" as
	action.

	* Makefile (install): Pass installation directories as arguments
	to ldconfig.

1997-02-02 23:15  Ulrich Drepper  <drepper@cygnus.com>

	* malloc/malloc.c (__after_morecore_hook): New variable.
	(malloc_extend_top): Call __after_morecore_hook if set.
	(main_trim): Likewise.
	* malloc/malloc.h: Add declaration of __after_morecore_hook.
	Suggested by Marcus Daniels.

1997-02-02 23:00  Marcus G. Daniels  <marcus@tdb.com>

	* malloc/malloc.c (rEALLOc): Protect tsd_setspecific call by
	#ifndef NO_THREADS.
	(mallinfo): Likewise.

	* malloc/malloc.c (__morecore): Make external since it is used in
	programs.

1997-02-02 15:10  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/statbuf.h (struct stat): Make st_dev field
	unsigned.

1997-02-01 23:36  Richard Henderson  <rth@tamu.edu>

	* sysdeps/alpha/stxncpy.S ($unaligned) [src % 8 > dst % 8]: Don't
	use t6 as a temporary; it contains bits we still need in $u_head.

1997-01-31 15:05  John Bowman  <bowman@ipp-garching.mpg.de>

	* sysdeps/i386/fpu/__math.h [__USE_MISC]: Don't declare prototypes
	using __ prefix.  Add prototype for log1p.
