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>.
