* elf/rtld.c (dl_main): Call _dl_sysdep_start_cleanup after
	_dl_relocate_object loop.  Avoid relocating RTLD_MAP in that loop, and
	do it individually if necessary after _dl_sysdep_start_cleanup call.

	* stdlib/Makefile (mpn-routines): Add divrem.

Tue Mar 26 22:54:14  Ulrich Drepper  <drepper@gnu.ai.mit.edu>

	* stdio-common/printf_fp.c (__printf_fp): Use mpn_divmod
	instead of __mpn_divmod.

Wed Mar 27 10:26:21 1996  David Mosberger-Tang  <davidm@azstarnet.com>

	* sysdeps/alpha/setjmp.S: Must establish global pointer before
 	address of __sigsetjmp_aux can be loaded.

Wed Mar 27 02:23:19 1996 Ulrich Drepper <drepper@gnu.ai.mit.edu>

	* sysdeps/i386/i586/memset.S: New file.  Highly optimized
	version for i586 contributed by Torbjorn Granlund.
	Adapted for use as bzero.
	* sysdeps/i386/i586/bzero.S: Use sysdeps/i386/i586/memset.S
	code to implement bzero().

	* stdlib/Makefile (mpn-routines): Remove divmod.
