emacs/nt/inc/sys/time.h, branch scratch/kqueue

Attempt to resolve gettimeofday compilation errors with MinGW64.

2013-06-03T17:15:44+00:00

 src/w32.c (gettimeofday): Make the signature identical to prototype
 in nt/inc/sys/time.h.

 nt/inc/sys/time.h (struct timeval): Remove the _W64 guards.

Fix compilation error on MinGW64 due to nt/inc/sys/time.h.

2013-06-01T07:07:22+00:00

 nt/inc/sys/time.h [!_TIMEZONE_DEFINED]: Define _TIMEZONE_DEFINED to
 avoid multiple definition errors on MinGW64.

Fix compile errors in nt/inc/sys/time.h when using nt/configure.bat.

2013-05-31T08:47:18+00:00

 nt/inc/sys/time.h (gettimeofday): Use '__restrict' instead of
 'restrict', which is a C99 extension.  See
 http://lists.gnu.org/archive/html/emacs-devel/2013-05/msg00588.html
 and the following discussion for the problem this caused in the
 old nt/configure.bat build.

Use 'restrict' in gettimeofday arguments, and make ms-w32.h compatible.

2013-03-28T20:51:26+00:00

Fix the gettimeofday_timezone test.

2013-03-28T20:20:40+00:00

Merge from trunk and resolve conflicts.

and in
  http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00707.html.

 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.

Fix incompatibilities between MinGW.org and MinGW64 headers

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.

Fixed configure.ac and headers in nt/inc. Emulated functions not handled yet.

Support atimers and CPU profiler via profile.c on MS-Windows.

2012-09-30T15:49:05+00:00

 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  [_MSVC_VER]: Make the typedef consistent
 with MinGW.
 (SA_RESTART, SIGPROF): Define.
 nt/config.nt (HAVE_SETITIMER): Define to 1.
