rpc.
* hurd/hurdmsg.c (_S_msg_set_environment): Use argz.h functions
instead of _hurd_split_args.

(_S_msg_startup_dosync): Stub removed.
Sat May 4 02:11:55 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* sysdeps/mach/hurd/ptrace.c: Set _hurdsig_traced instead of
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.

(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.
* string/argz-next.c: Likewise.

* sysdeps/mach/hurd/sigaction.c: Likewise.
* sysdeps/mach/hurd/errnos.awk: Don't use ARGV in comment; it can
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.
(_hurd_critical_section_unlock): Unlock SS->critical_section_lock
instead of clearing the old flag member.
* hurd/hurdsig.c (_hurd_internal_post_signal): Use spin_lock_locked to
test the critical section state.
* hurd/hurdinit.c (_hurd_init): Set _hurdsig_traced from the intarray.
* hurd/hurdkill.c (_hurd_sig_post): Pass 0 sigcode in msg_sig_post.
* hurd/hurdsig.c (_hurd_internal_post_signal): Test _hurdsig_traced
instead of testing (_hurd_exec_flags & EXEC_TRACED).

testing (_hurd_exec_flags & EXEC_TRACED).
Pass sigcode arg to msg_sig_post.
* hurd/hurd.h: Declare _hurdsig_traced.
* 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.
* hurd/Makefile (routines): Add path-lookup.
* hurd/hurd/lookup.h: Declare file_name_path_scan,
hurd_file_name_path_lookup.
* hurd/hurd.h: Declare file_name_path_lookup.

argument. Instead, use a separate reply port for each RPC and put them
all in a port set to wait for slow replies.
