Update.
2004-06-17 Ulrich Drepper <drepper@redhat.com> * sysdeps/pthread/pthread_cond_timedwait.c (__pthread_cond_timedwait): Also check for negativ nanoseconds. * sysdeps/unix/sysv/linux/i386/i486/pthread_cond_timedwait.S (__pthread_cond_timedwait): Check for invalid nanosecond in timeout value. * sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S: Likewise. * tst-cond19.c: New file. * Makefile: Add rules to build and run tst-cond19.
