Update.
2003-01-13  Ulrich Drepper  <drepper@redhat.com>

	* string/tester.c (test_strcpy): Use the previously #if 0'ed code
	to test void* parameters.

	* sysdeps/i386/i486/bits/string.h (__STRING_SMALLL_GET16): Cast
	source pointer before dereferencing.
	(__STRING_SMALLL_GET32): Likewise.
	(__memset_gc): Add missing parenthesis around macro arguments.
	Patch by Denis Zaitsev<zzz@cd-club.ru>.

	* sysdeps/i386/i486/bits/string.h (__strspn_cg): Tell the compiler
	that %eax is modified.  Reported by Denis Zaitsev<zzz@cd-club.ru>.
