	EXEC_TRACED bit in _hurd_exec_flags.
	Pass sigcode arg in msg_sig_post_untraced rpc.

	* sysdeps/mach/hurd/access.c: Don't pass io port in
	auth_user_authenticate rpc.

	* posix/sched.h: Fix typos.

	* sysdeps/mach/hurd/fork.c: Use new critical section lock.

	(envz_get, envz_remove): Likewise.
	(envz_entry): Return char *, not const char *.

	* string/envz.h: Fix decl.

	* string/argz-create.c: Use const in prototype.

	change meaninglessly.

	* 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.

	* hurd/path-lookup.c: New file.
