Update.
2003-04-14  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/i386/i486/bits/atomic.h: Rename LOCK to LOCK_PREFIX.
	* sysdeps/x86_64/bits/atomic.h: Likewise.

2003-04-14  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/i386/sysdep.h: Change PUSHARGS_1 and
	POPARGS_1 to emit labels for the mov instructions.

2003-04-14  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h (ret_NOERRNO): Define.
