Update.

2003-03-25  Ulrich Drepper  <drepper@redhat.com>

	* csu/tst-atomic.c: Adjust tests to what atomic_add_negative and
	atomic_add_zero were supposed to do.
	* include/atomic.h: Adjust atomic_add_negative and atomic_add_zero
	to x86 behavior.

	* sysdeps/generic/bits/typesizes.h (__TIMER_T_TYPE): Define as void*.
	This matches the new timer implementation.
	* sysdeps/unix/sysv/linux/bits/siginfo.h (struct siginfo): Adjust
	timer info for what the kernel provides these days.
	(struct sigevent): Add _tid field.
	Define SIGEV_THREAD_ID.

	* Versions.def (librt): Add GLIBC_2.3.3.

	* abilist/libpthread.abilist: Update for nptl.
