Update.

2000-02-12  Andreas Jaeger  <aj@suse.de>

	* sysdeps/unix/sysv/linux/i386/msgctl.c (__new_msgctl): Move errno
	declaration to place where it's needed to avoid compiler warning.
	* sysdeps/unix/sysv/linux/i386/semctl.c (__new_semctl): Likewise.

	* locale/weightwc.h (findidx): Correct find index value.

+	* condvar.c (pthread_cond_timedwait_relative_old): Undo last patch
+	but keep the code around.  A bug in the kernel prevent us from
+	using the code.
+	(pthread_cond_timedwait_relative_new): Likewise.
+	(PR libc/1597 and libc/1598).
