src/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. src/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. src/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. src/xdisp.c (start_hourglass, cancel_hourglass): Now used on WINDOWSNT as well. (start_hourglass) [WINDOWSNT]: Call w32_note_current_window. src/w32.h (init_timers, term_timers): Add prototypes. nt/inc/sys/time.h (ITIMER_REAL, ITIMER_PROF): Define. (struct itimerval): Define. (getitimer, setitimer): Add prototypes. nt/inc/ms-w32.h <sigset_t> [_MSVC_VER]: Make the typedef consistent with MinGW. (SA_RESTART, SIGPROF): Define. nt/config.nt (HAVE_SETITIMER): Define to 1.
