	* hurd/hurd/signal.h (struct hurd_sigstate): Replace critical section
 	flag with a spin lock.
	(_hurd_critical_section_lock): Use spin_try_lock on that to see if we
 	get it.  No need to take SS->lock at all.

	* string/argz.h (__argz_next): Cast ENTRY before returning it.

	* hurd/hurd/signal.h (_hurd_critical_section_unlock): Pass sigcode arg
	to msg_sig_post.
