[PATCH] Tiny libc fixes

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

1) Reverting the %% whitespace change from yesterday.
   Some OSes don't eat the whitespace there while others do, the ISO C99 standard
   only lists %c, %[ and %n as not eating whitespace, so it is probably
   better to stay with previous glibc behaviour here.
2) 3 warning fixes
3) fix sparcv9 build

2004-04-20  Jakub Jelinek  <jakub@redhat.com>

	* stdio-common/vfscanf.c (_IO_vfscanf): Revert last %% whitespace
	handling change.
	* stdio-common/tst-sscanf.c (int_tests): Adjust.

	* nss/nss-nis.c: Include stdlib.h.

	* sysdeps/sparc/sparc32/dl-machine.h (elf_machine_rela): Shut up a
	warning.
	* sysdeps/sparc/sparc64/memcmp.S (memcmp): Remove BP_SYM () from
	libc_hidden_builtin_def.
linuxthreads/
	* oldsemaphore.c (SEM_VALUE_MAX): Remove.
