* process.c: (status_convert): Declare this to return a

	Lisp_Object at the top of the file.
	(decode_status): Don't untag XCONS (tem)->cdr before storing it in
	tem; tem is a Lisp_Object, too.
	(process_send_signal): Declare this to be static void.  Don't
	return Qnil; nobody cares.
	(sigchld_handler): Use XFASTINT to manipulate p->infd.

	* process.c (pty_process): Variable deleted; it's no longer used.
	(syms_of_process): Don't initialize it.
