From Peter Schauer <Peter.Schauer@Regent.E-Technik.TU-Muenchen.DE>
* 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().
