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.
