* hurd/new-fd.c (_hurd_new_fd): Initialize fcntl flags.
	* hurd/port2fd.c (_hurd_port2fd): Reset the fcntl flags when
	installing PORT in the descriptor cell.

1999-08-19  Roland McGrath  <roland@baalperazim.frob.com>

	* sysdeps/mach/hurd/i386/intr-msg.h (INTR_MSG_TRAP): Mark OPTION and
	TIMEOUT as outputs of the asm to indicate that the signal thread
	might mutate them.
	* hurd/intr-msg.c (_hurd_intr_rpc_mach_msg): Short circuit to plain
	mach_msg if only sending or only receiving (i.e., not an RPC).  When
	making an RPC that might get interrupted, save OPTION and the portion
	of the message buffer that gets clobbered by an EINTR reply message,
	and properly restore them before attempting to retry the request
	message send.
