+        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.
+
+        * w32fns.c (hourglass_timer, HOURGLASS_ID): Remove.
+        Windows-specific code to display the hourglass mouse pointer is no
+        longer used.
+        (w32_wnd_proc): Remove code that handled the WM_TIMER message due
+        to hourglass timer expiration.
+        (start_hourglass, cancel_hourglass, DEFAULT_HOURGLASS_DELAY):
+        Remove, no longer used.
+        (w32_note_current_window, show_hourglass, hide_hourglass): New
+        functions, in support of hourglass cursor display similar to other
+        window systems.
+        (syms_of_w32fns): Don't initialize hourglass_timer.
+
+        * xdisp.c (start_hourglass, cancel_hourglass): Now used on
+        WINDOWSNT as well.
+        (start_hourglass) [WINDOWSNT]: Call w32_note_current_window.
+
+        * w32.h (init_timers, term_timers): Add prototypes.
