	* hurd/thread-cancel.c: New file.
	* sysdeps/mach/hurd/i386/trampoline.c (_hurd_setup_sighandler): In
 	rpc_wait case, frob mach_msg args to set timeout on receive.
	(_hurdsig_rcv_interrupted_p): Function removed.
	* sysdeps/mach/hurd/alpha/trampoline.c: Likewise.
	* sysdeps/mach/hurd/hppa/trampoline.c: Likewise.
	* sysdeps/mach/hurd/mips/trampoline.c: Likewise.
	* hurd/intr-msg.c: New file.
	* hurd/hurd/signal.h (struct hurd_sigstate): New member `cancel'.
	(_hurdsig_rcv_interrupted_p): Declaration removed.
	(HURD_EINTR_RPC): Macro removed.
	(_hurd_longjmp_thread_state, _hurd_interrupted_rpc_timeout): Declare
	these.
	* hurd/intr-rpc.h: New file.
	* hurd/intr-rpc.defs: Just import intr-rpc.h.
	* hurd/hurdsig.c (_hurd_interrupted_rpc_timeout): New variable.
	(interrupted_reply_port_location): Take new flag arg; only catch
	faults if it's set.
	(abort_rpcs): Rename to _hurdsig_abort_rpcs; take same new flag arg.
	No longer use _hurdsig_rcv_interrupted_p; instead compare PC to
 	&_hurd_intr_rpc_msg_in_trap.  If before it, mutate state to simulate
 	MACH_SEND_INTERRUPTED return; on it, interrupt the operation.  All
 	callers changed.
	* hurd/hurd.h (hurd_thread_cancel, hurd_check_cancel): Declare these.
	* hurd/Makefile (distribute): Remove intr-rpc.awk.
	(sig): Add thread-cancel.
	(transform-user-stub, transform-user-stub-output): Variables removed.
	* sysdeps/mach/hurd/dl-sysdep.c: Change all RPCs from
 	`__hurd_intr_rpc_*' to `__*'.
	(_hurd_intr_rpc_mach_msg): New function.
	(_hurd_thread_sigstate): Function removed.
	* sysdeps/mach/hurd/ioctl.c: Use _hurd_intr_rpc_mach_msg function,
 	instead of __mach_msg inside HURD_EINTR_RPC macro.

	* sysdeps/generic/morecore.c [__GNU_LIBRARY__]: Declare `__sbrk'
 	to take ptrdiff_t arg.

	* sysdeps/mach/hurd/fork.c: Remove _hurd_longjmp_thread_state decl.

	* sysdeps/mach/hurd/kill.c (kill_pid): Don't make `inline'.

	* libc-symbols.h [GCC >= 2.7] (strong_alias, weak_symbol,
 	weak_alias): Use `extern' storage class.
