This replaces macros (which typically do not work in GDB)
with functions, typedefs and enums, making the code easier to debug.
The functional style also makes code easier to read and maintain.
* lib-src/profile.c (TV2): Remove no-longer-needed static var.
* src/systime.h: Include <sys/time.h> on all hosts, not just if
WINDOWSNT, since 'struct timeval' is needed in general.
(EMACS_TIME): Now a typedef, not a macro.
(EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
not macros.
(EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
(EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
(EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
(EMACS_TIME_LE): Now functions, not macros.
(EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
(EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
which are not functions. All uses rewritten to use:
(make_emacs_time): New function.
(EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
(EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
not functions. All uses rewritten to use the following, respectively:
(emacs_secs_addr, invalid_emacs_time, get_emacs_time)
(add_emacs_time, sub_emacs_time): New functions.
* src/atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
* src/fileio.c (Fcopy_file):
* src/xterm.c (XTflash): Get the current time closer to when it's used.
* src/makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
* atimer.c (start_atimer): Use EMACS_TIME, not struct timeval.
* sysdep.c (set_file_times): Use EMACS_TIME, not struct timeval.
* xgselect.c (xg_select): Use SELECT_TYPE, EMACS_TIME.
* atimer.c (set_alarm): Remove dead code, all USG systems define
POSIX_SIGNALS.
* data.c (arith_error): Likewise.
* keyboard.c (input_available_signal, handle_user_signal)
(interrupt_signal): Likewise.
* process.c (sigchld_handler): Likewise.
(create_process): Remove if 0 code. Remove HPUX conditional when
!defined (POSIX_SIGNALS), it cannot be true.
* syssignal.h: Remove USG5_4 and USG conditionals when
!POSIX_SIGNALS, they cannot be true.
with alarm based polling.
mac.c (sys_select): Redo sys_select to use alarm-based
polling instead of 1 sec timeouts (like solaris).
macterm.c (x_make_frame_visible): Comment in polling on
frame creation.
keyboard.c: Undef SIGIO on Carbon
atimer.c (alarm_signal_handler): Call alarm handlers after
scheduling.
eval.c (Feval): Remove quit_char test
process.c (wait_reading_process_input): Remove clearing
stdin for select call on process input
