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>.
