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.
