+ Support atimers and CPU profiler via profile.c on MS-Windows.
+ * w32proc.c (sig_mask, crit_sig): New static variables.
+ (sys_signal): Support SIGALRM and SIGPROF.
+ (sigemptyset, sigaddset, sigfillset, sigprocmask)
+ (pthread_sigmask, setpgrp): Moved here from w32.c. sigaddset,
+ sigfillset, and sigprocmask are no longer no-ops.
+ (sigismember): New function.
+ (struct itimer_data): New definition.
+ (ticks_now, real_itimer, prof_itimer, clocks_min, crit_real)
+ (crit_prof): New static variables.
+ (MAX_SINGLE_SLEEP): New definition.
+ (timer_loop, stop_timer_thread, term_timers, init_timers)
+ (start_timer_thread, getitimer, setitimer): New functions.
+ (alarm): No longer a no-op, calls setitimer.
+
+ * w32.c (term_ntproc): Call term_timers.
+ (init_ntproc): Make sure all signals are unblocked at startup, to
+ erase any traces of dumping. Call init_timers.

+ Remove, no longer used.
