Update.
2003-01-28  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/common/pause.c (do_pause): New function.  Split
	from __libc_pause.  Implement using sigsuspend.
	(__libc_pause): Call do_pause to do the real work.

	* sysdeps/posix/sigpause.c (do_sigpause): Check range of
	sig_or_mask parameter is is_sig != 0.
