Update.
2003-02-06 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_wait.S: Remove wrong but inactive generalization. * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_timedwait.S: Likewise. * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_signal.S: Likewise. Minor optimization, remove one instruction. * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_broadcast.S: Likewise.
