Subject: Remove dead code dealing with POSIX_SIGNALS. * atimer.c (set_alarm):
 Remove dead code, all USG systems define POSIX_SIGNALS. * data.c
 (arith_error): Likewise. * keyboard.c (input_available_signal,
 handle_user_signal) (interrupt_signal): Likewise. * process.c
 (sigchld_handler): Likewise. (create_process): Remove if 0 code.  Remove HPUX
