* nt/inc/sys/time.h (_TIMEVAL_DEFINED, struct timevat, timerisset)
(timercmp, timerclear): Don't define. Instead, include the system
header sys/time.h, and add only the interval timers stuff. This
avoids compiler warnings about 'gettimeofday's prototype, and also
avoids redefinition of macros from system headers.
* lib-src/ntlib.c (gettimeofday):
* nt/inc/sys/time.h (gettimeofday, struct timezone): Remove unused
function 'gettimeofday' and all of its supporting code.

nt/inc/ms-w32.h (USE_NO_MINGW_SETJMP_TWO_ARGS) [_W64]: Define to 1.
For MinGW64, include sys/types.h and time.h.
nt/inc/sys/time.h (struct timeval) [!_W64]: Guard definition with _W64.
(struct timezone) [!_TIMEZONE_DEFINED]: Guard definition with
_TIMEZONE_DEFINED.
nt/addpm.c (_WIN32_IE) [_W64]: For MinGW64, don't define to 0x400.
nt/inc/sys/stat.h: Remove _CRTIMP from prototypes of fstat, stat,
lstat, and fstatat.
lib-src/ntlib.c (struct timespec) [!_TIMEZONE_DEFINED]: Define the
struct only if _TIMEZONE_DEFINED is not defined.
src/w32term.c (WCRANGE, GLYPHSET): Don't define if _W64 is defined.
src/w32.c (REPARSE_DATA_BUFFER): Guard with
MAXIMUM_REPARSE_DATA_BUFFER_SIZE being defined.
Problems were reported by ׃scar Fuentes in
http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00611.html.
nt/inc/ms-w32.h (struct timespec): Don't define if
_TIMESPEC_DEFINED is already defined.
(sigset_t) [!_POSIX]: Typedef for MinGW64.
(_WIN32_WINNT, WIN32_LEAN_AND_MEAN): Move definitions before
including the first system header, to avoid redefinition if some
system header defines a default value.
nt/inc/sys/time.h (struct itimerval): Don't define if
_TIMESPEC_DEFINED is already defined.
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.
lib/makefile.w32-in ($(BLD)/dtotimespec.$(O)):
($(BLD)/timespec-add.$(O)):
($(BLD)/timespec-sub.$(O)): Don't depend on
$(EMACS_ROOT)/nt/inc/sys/time.h.
lib/stat-time.h:
lib/timespec.h:
lib/utimens.h: Revert last change.
src/makefile.w32-in (TIMESPEC_H): Remove nt/inc/sys/time.h.
(SYSTIME_H): Add nt/inc/sys/time.h.
src/systime.h [WINDOWSNT]: Include sys/time.h.
src/s/ms-w32.h (struct timespec): Definition moved from
nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
nt/inc/sys/time.h (struct timespec): Don't define it here, it is
now defined in src/s/ms-w32.h.
