This portability layer is no longer needed, since Emacs has been using struct timespec as a portability layer for some time. Merge from gnulib, incorporating: 2013-08-27 timespec: new convenience constants and function * src/atimer.h, src/buffer.h, src/dispextern.h, src/xgselect.h: Include <time.h> rather than "systime.h"; that's all that's needed now. * src/dispnew.c: Include <timespec.h> rather than "systime.h"; that's all that's needed now. * src/systime.h (EMACS_TIME): Remove. All uses changed to struct timespec. (EMACS_TIME_RESOLUTION): Remove. All uses changed to TIMESPEC_RESOLUTION. (LOG10_EMACS_TIME_RESOLUTION): Remove. All uses changed to LOG10_TIMESPEC_RESOLUTION. (EMACS_SECS, emacs_secs_addr): Remove. All uses changed to tv_sec. (EMACS_NSECS): Remove. All uses changed to tv_nsec. (make_emacs_time): Remove. All used changed to make_timespec. (invalid_timespec): Rename from invalid_emacs_time. All uses changed. (current_timespec): Rename from current_emacs_time. All uses changed. (add_emacs_time): Remove. All uses changed to timespec_add. (sub_emacs_time): Remove. All uses change dot timespec_sub. (EMACS_TIME_SIGN): Remove. All uses changed to timespec_sign. (timespec_valid_p): Rename from EMACS_TIME_VALID_P. All uses changed. (EMACS_TIME_FROM_DOUBLE): Remove. All uses changed to dtotimespec. (EMACS_TIME_TO_DOUBLE): Remove. All uses changed to timespectod. (current_timespec): Rename from current_emacs_time. All uses changed. (EMACS_TIME_EQ, EMACS_TIME_LT, EMACS_TIME_LE): Remove. All uses changed to timespec_cmp. * src/xgselect.c: Include <timespec.h>, since our .h files don't.
