2018-01-01 maint: Run 'make update-copyright'
2017-12-29 Add cross-compilation results for GNU/Hurd.
2017-12-12 explicit_bzero: port to macOS + Clang 9.0.0
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
This incorporates:
2017-08-15 renameat: ensure declaration in <stdio.h> on NetBSD
2017-08-15 extensions: enable NetBSD specific extensions
2017-08-14 open: support O_CLOEXEC
2017-08-13 reallocarray: new module
* admin/merge-gnulib (AVOIDED_MODULES): Remove ‘open’, since
it now supports O_CLOEXEC and this simplifies Emacs.
* build-aux/config.guess, lib/fcntl.in.h, lib/stdio.in.h:
* lib/stdlib.in.h, m4/extensions.m4, m4/stdlib_h.m4:
Copy from Gnulib.
* lib/cloexec.c, lib/cloexec.h, lib/open.c:
* m4/mode_t.m4, m4/open-cloexec.m4, m4/open.m4:
New files, copied from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib-src/etags.c (O_CLOEXEC) [WINDOWSNT]:
Remove, as Gnulib does this for us.
* src/filelock.c (create_lock_file):
* src/sysdep.c (emacs_open, emacs_pipe):
Don’t worry about O_CLOEXEC == 0, as Gnulib no longer sets it to 0.
For the motivation behind this patch, please see Bug#28023 and:
http://emacshorrors.com/posts/make-temp-name.html
Although, given the recent changes to Tramp, the related security
problem in make-temp-file is already fixed, make-temp-file still has
several unnecessary system calls. In the typical case on GNU/Linux,
this patch replaces 8 syscalls (symlink, open, close, readlinkat, uname,
getpid, unlink, umask) by 2 (open, close).
* admin/merge-gnulib (GNULIB_MODULES): Add tempname, now
that Emacs is using it directly.
* configure.ac (AUTO_DEPEND): Remove AC_SYS_LONG_FILE_NAMES;
no longer needed.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lisp/files.el (files--make-magic-temp-file): Rename from
make-temp-file.

instead of make_temp_name.

stat-like functions on GNU/Linux and other platforms with d_type.

need to try first with AT_SYMLINK_NOFOLLOW since the directory
entry was already checked to exist.

current buffer. The Myers algorithm is implemented in Gnulib.

2008-06-13 [BZ #6612] pass reference to tzset_called around
2007-10-16 [BZ #5184] Add tzset_called argument
* build-aux/snippet/c++defs.h, lib/strftime.c, lib/sys_time.in.h:
* m4/manywarnings.m4: Copy from gnulib.
This incorporates:
2016-10-16 qsort_r: Fix macrology for platforms that lack the function.
2016-10-13 stdint: port SIZE_MAX to glibc s390
2016-10-11 maint: remove stray space after "." in AC_DEFINE comment.
* lib/gnulib.mk: Regenerate.
* lib/stdlib.in.h, m4/st_dm_mode.m4, m4/stdint.m4, m4/stdlib_h.m4:
* m4/utimes.m4: Copy from gnulib.
The NetBSD library supports localtime_rz directly, and without
this change 'configure' omitted the flexmember test that is marked
as conditional on localtime_rz. Emacs now needs to use
flexmember.m4 even when localtime_rz works.
Problem reported by Thomas Klausner.
* admin/merge-gnulib (GNULIB_MODULES): Add flexmember.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
This removes a workaround where Emacs did not use flexible
array members when compiled with IBM XL C. Instead, avoid
the problem by making the aliasing issues more obvious to
this compiler.
* admin/merge-gnulib: Don’t remove m4/flexmember.m4.
* m4/flexmember.m4: Copy from gnulib.
* configure.ac (AC_C_FLEXIBLE_ARRAY_MEMBER): Remove workaround.
* src/alloc.c (allocate_string_data): Rephrase to avoid aliasing
problem that would otherwise mess up code generated for flexible
array members by IBM XL C for AIX, V12.1.
* src/conf_post.h (FLEXIBLE_ARRAY_MEMBER): Remove; now done
by gnulib code.
