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().
