1998-08-26 17:48  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-close.c (_dl_close): Move map->l_nsearchlist value into local
	variable so that map can be freed.
	Reported by Philippe Troin <phil@fifi.org>.

	* elf/dl-open.c (dl_open_worker): Correct test for extending global
	scope array.
	Patch by Philippe Troin <phil@fifi.org>.

1998-08-26  Geoff Keating  <geoffk@ozemail.com.au>

	* sysdeps/powerpc/register-dump.h: Rewrite.  Much nicer this way.
	Don't call writev() with a 100-element vector.
	* sysdeps/generic/segfault.c (catch_segfault): Skip top-level NULL
	return address.

	* sysdeps/powerpc/elf/libc-start.c: Sync up with generic version.
	In particular, set __libc_stack_end.
	* sysdeps/powerpc/elf/start.S: Allow _init and _fini to be
	undefined.  Fix copyright notice.

1998-08-25  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* math/Makefile (gmp-objs): New variable.
	($(objpfx)atest-exp, $(objpfx)atest-sincos, $(objpfx)atest-exp2):
	Depend on it.
	(tests): Add atest-exp atest-sincos atest-exp2.
	(tests-static): Remove atest-exp atest-sincos atest-exp2.

	* elf/rtld.c (dl_main): Unload map file before jumping to user code.
