The change in boot-time.c imported from Gnulib broke the
MinGW build using mingw.org's MinGW. It is wrong to include
sysinfoapi.h, MS documentation says to include <windows.h>.
* lib/boot-time.c: Don't include sysinfoapi.h.
C23's <stdbit.h> in the long run should be better supported than
Gnulib's count-one-bits.h and similar headers, so switch to the
C23 primitives, with a Gnulib fallback for platforms lacking C23.
* admin/merge-gnulib (GNULIB_MODULES): Remove count-leading-zeros,
count-one-bits, count-trailing-zeros. Add stdc_bit_width,
stdc_count_ones, stdc_trailing_zeros.
* lib/count-leading-zeros.c, lib/count-leading-zeros.h:
* lib/count-one-bits.c, lib/count-one-bits.h:
* lib/count-trailing-zeros.c, lib/count-trailing-zeros.h: Remove.
* lib/stdbit.c, lib/stdbit.in.h, lib/stdc_bit_width.c:
* lib/stdc_count_ones.c, lib/stdc_leading_zeros.c:
* lib/stdc_trailing_zeros.c, m4/stdbit_h.m4:
New files, copied from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/data.c: Do not include count-one-bits.h, count-trailing-zeros.h.
Instead, rely on lisp.h including stdbit.h.
(Flogcount, Fbool_vector_count_population)
(Fbool_vector_count_consecutive): Use stdbit.h macros instead of
count-one-bits.h and count-trailing-zeros.h macros.
(shift_right_ull, count_one_bits_word, pre_value)
(count_trailing_zero_bits): Remove; no longer needed.
* src/lisp.h: Include stdbit.h instead of count-leading-zeros.h.
(elogb): Use stdbit.h macro instead of count-leading-zeros.h macro.
Simplify Emacs proper by using Gnulib’s boot-time module
instead of doing it all by hand. This should port Emacs
better to obscurish hosts, as Bruno Haible has merged the
best of Emacs’s and Gnulib’s boot-time gathering.
* lib/boot-time-aux.h, lib/boot-time.c, lib/boot-time.h:
* lib/readutmp.h, m4/readutmp.m4: New files, copied from Gnulib.
* admin/merge-gnulib (GNULIB_MODULES): Add boot-time.
* configure.ac: Do not check for utmp.h;
the boot-time module now does this.
(BOOT_TIME_FILE): Remove; no longer used.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/filelock.c [__FreeBSD__]: Do not include <sys/sysctl.h>.
[HAVE_UTMP_H]: Do not include utmp.h.
Include boot-time instead: boot-time does the work now.
(BOOT_TIME) [HAVE_ANDROID && !ANDROID_STUBIFY]: Don’t undef.
(WTMP_FILE): Don’t define.
(boot_time, boot_time_initialized, get_boot_time_1, get_boot_time):
Remove.
(get_boot_sec): New function that simply calls Gnulib get_boot_time.
(lock_file_1, current_lock_owner): Use get_boot_sec instead
of get_boot_time.
It’s not worth the porting hassle, and as the glibc manual says,
“this function is generally a poor choice for processing strings”.
* admin/merge-gnulib (GNULIB_MODULES): Remove stpncpy.
* exec/configure.ac: Do not check for stpncpy.
* exec/exec.c (rpl_stpncpy, stpncpy): Remove this replacement.
(exec_0): Properly clear buffer1. Use memcpy instead of
stpncpy to add the trailing name. This code is clearly
still suboptimal but efficiency is not that important here
and I tried to minimize the change.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* m4, lib: Update from Gnulib.
* msdos/sedlibmk.inp: Remove variables deleted as part of previous
change.
* admin/merge-gnulib (GNULIB_MODULES): Remove vasprintf and
printf-posix.
* configure.ac (gl_STDLIB_H): Replace this, not gt_LOCALE_FR_UTF8,
as this lets us also omit MB_CUR_MAX checking that will never be
executed, and also lets us remove testing for ecvt, fcvt, gcvt
that Emacs doesn’t need.
(AC_C_RESTRICT): Invoke explicitly, as Emacs uses ‘restrict’
directly. Also, simplifies the replacement for gl_STDLIB_H, which
would otherwise need to AC_REQUIRE AC_C_RESTRICT.
* lib/gnulib.mk.in: Regenerate via admin/merge-gnulib.
* admin/merge-gnulib: Remove m4/locale-fr.m4.
* configure.ac (gt_LOCALE_FR_UTF8): Replace Gnulib’s
definition with a near no-op, as Emacs doesn’t care
about the Solaris 10 MB_CUR_MAX bug.
* lib/gnulib.mk.in: Regenerate.
* m4/locale-fr.m4: Remove; no longer needed due
to above changes.
This adds support for 64-bit time_t on 32-bit GNU/Linux ARM and
x86, where time_t was historically 32-bit. The resulting Emacs
should continue to work for timestamps after mid-January 2038.
* admin/merge-gnulib (GNULIB_MODULES): Add year2038.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
Run admin/merge-gnulib along with the following change:
* admin/merge-gnulib (GNULIB_MODULES): Replace ‘time’ with
‘time-h’, adjusting to a recent renaming in Gnulib modules.
Emacs doesn’t appear to need the new Gnulib ‘time’ module.
