* procfs.c (wait_fd):  Handle EINTR error return from poll
        by restarting the poll.
	* defs.h (PIDGET): Define a default version that just
	returns its argument unchanged.
	* inflow.c (terminal_init_inferior): Eliminate #ifdef
	of PIDGET and fold both alternatives into common code.
	(pass_signal): Use PIDGET for pid passed to kill().
