as it’s simpler and is a POSIX API.
* src/sysdep.c (set_file_times): Move from here ...
* src/w32.c (set_file_times): ... to here, and make it static,
since it is now used only in w32.c. Presumably w32.c should also
add support for futimens and utimensat (the POSIX APIs, which
Emacs now uses) and it can remove fdutimens (the Gnulib API,
which Emacs no longer uses).
This avoids some race conditions (Bug#39683). E.g., if some other
program changes a file to a symlink between the time Emacs creates
the file and the time it changes the file’s permissions, using the
new flag prevents Emacs from inadvertently changing the
permissions of a victim in some completely unrelated directory.

It’s not needed, since Emacs always uses the system putenv and all
platforms have putenv. This improves on the fix for Bug#19874.
Suggested by Bruno Haible.
* admin/merge-gnulib (GNULIB_MODULES): Remove putenv.

etags had undefined behavior if input files, lines, tags, etc.,
had more than INT_MAX bytes. Clean up the usage of integer types
to fix the overflow errors I found.
* admin/merge-gnulib (GNULIB_MODULES): Add mempcpy.
* lib-src/etags.c: Include inttypes.h, intprops.h.
(memcpyz): New function. Use it to simplify several occurrences
of memcpy followed by storing a trailing '\0'.
(xnew): Use xnmalloc, to catch overflow on integer multiplication.
(xrnew): Change last arg to multiplier. The type is not needed.
All callers changed.
(node, lineno, charno, linecharno, invalidcharno, make_tag):
(pfnote, add_node, number_len, C_symtype, lbz, Makefile_targets)

(linebuffer_setlen):
Use ptrdiff_t for object sizes, instead of int or long or unsigned
or size_t.
(write_classname, C_entries):
Avoid sprintf, as the result could exceed INT_MAX bytes
and then behavior goes haywire.
(main): Use int, instead of unsigned, for argv counts.
(get_language_from_filename): Use bool for boolean.
(Ruby_functions): Prefer strcpy to memcpy when copying "=".
(linebuffer_setlen): Use ‘if’ instead of ‘while’.
(memory_full, xnmalloc, xnrealloc): New functions.

* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/mempcpy.c, m4/mempcpy.m4: New files, copied from Gnulib.
* admin/merge-gnulib (GNULIB_MODULES): Add double-slash-root.
Emacs was already using this Gnulib module indirectly, so this
is merely noting that there is now a direct dependency.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/fileio.c (search_embedded_absfilename):
Use DOUBLE_SLASH_IS_DISTINCT_ROOT instead of (WINDOWSNT || CYGWIN).
Simplify.
PATH_MAX is standardized, MAXPATHLEN is not.
Also, the Gnulib pathmax module fixes some rare bugs with PATH_MAX.
So prefer PATH_MAX to MAXPATHLEN unless we know the latter is
also correct (for some platform-specific code).
* admin/merge-gnulib (GNULIB_MODULES): Add pathmax.
This module was already present, as a dependency of canonicalize-lgpl,
but now Emacs is using it directly. Sort.
* lib-src/emacsclient.c: Include stdint.h, pathmax.h.
(get_current_dir_name): Sync to current src/sysdep.c.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.

The copy_file_range syscall (introduced in Linux kernel
version 4.5) can copy files more efficiently via server-side
copy etc.
* admin/merge-gnulib (GNULIB_MODULES): Add copy-file-range.
* lib/copy-file-range.c, m4/copy-file-range.m4:
New files, copied from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/fileio.c (Fcopy_file): Try copy_file_range first,
falling back on read+write only if copy_file_range failed or
if the input is empty and so could be a /proc file.
* lib-src/emacsclient.c (set_local_socket):
Use faccessat with AT_EACCESS instead of using euidaccess.
* admin/merge-gnulib, lib/gnulib.mk.in, m4/gnulib-comp.m4:
Revert previous change.
* admin/merge-gnulib (GNULIB_MODULES): Add memmem-simple.
(AVOIDED_MODULES): Add memchr.
* configure.ac (HAVE_PDUMPER): AC_SUBST it, too, for use in makefiles.

copied from Gnulib.
* lib/fingerprint.h: Rename from src/fingerprint.h.
* lib-src/make-fingerprint.c: Include limits.h, sys/stat.h,
fingerprint.h, intprops.h, min-max.h.
(SSIZE_MAX): New macro, if not already defined.
(main): Without -r, Replace the fingerprint in the input file
instead of generating a fingerprint.c.
* lib/Makefile.in (libgnu_a_OBJECTS): Add fingerprint.o.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/Makefile.in (HAVE_PDUMPER, MAKE_PDUMPER_FINGERPRINT):
New macros.
(temacs$(EXEEXT)): Use them to replace the fingerprint instead
of precalculating it.
(mostlyclean, ctagsfiles1): Do not worry about fingerprint.c.
fdatasync is for storage devices, not ttys.
* admin/merge-gnulib (GNULIB_MODULES): Remove fdatasync.
* lib/fdatasync.c, m4/fdatasync.m4: Remove.
* lib-src/Makefile.in (LIB_FDATASYNC):
* src/Makefile.in (LIB_FDATASYNC):
Remove. All uses removed.
* lib-src/emacsclient.c [!DOS_NT]:
Include <termios.h>, for tcdrain.
* lib-src/emacsclient.c (flush_stdout):
* src/sysdep.c (reset_sys_modes): On ttys, use tcdrain instead
of fdatasync (except don’t use either function if DOS_NT).

Emacs regular expressions forked from everyone else long ago.
This makes it official and should allow simplification later.
etags.c now uses the glibc regex API, falling back on a
Gnulib-supplied substitute lib/regex.c if necessary.
Emacs proper now uses its own regular expression module.
Although this patch may look dauntingly large, most of it
was generated automatically by admin/merge-gnulib
and contains an exact copy of the glibc regex source,
and the by-hand changes do not grow the Emacs source code.
* admin/merge-gnulib (GNULIB_MODULES): Add regex.
(AVOIDED_MODULES): Add btowc, langinfo, lock, mbrtowc, mbsinit,
nl_langinfo, wchar, wcrtomb, wctype-h.
* lib-src/Makefile.in (regex-emacs.o): Remove; Gnulib does it now.
(etags_deps, etags_libs): Remove regex-emacs.o.
* lib-src/etags.c: Go back to including regex.h.
(add_regex): Use unsigned char translation array,
since glibc regex requires that.
* lib/Makefile.in (not_emacs_OBJECTS, for_emacs_OBJECTS): New macros.
(libegnu_a_OBJECTS): Use them, to avoid building e-regex.o.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.

(RE_TRANSLATE_TYPE, RE_TRANSLATE, RE_TRANSLATE_P):
Move from src/conf_post.h to src/regex-emacs.h,
so that they don’t interfere with compiling lib/regex.c.
* .gitignore: Add lib/ieee754.h.

* src/lread.c, src/print.c: Include <ieee754.h> if
IEEE_FLOATING_POINT, not if HAVE_IEEE754_H.
* src/lread.c (string_to_number):
* src/print.c (float_to_string):
Process NaNs only on IEEE hosts, and assume <ieee754.h>
in that case.

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.
(make-temp-file): Use make-temp-file-internal for
non-magic file names.
* src/fileio.c: Include tempname.h.
(make_temp_name_tbl, make_temp_name_count)
(make_temp_name_count_initialized_p, make_temp_name): Remove.
(Fmake_temp_file_internal): New function.
(Fmake_temp_name): Use it.
* src/filelock.c (get_boot_time): Use Fmake_temp_file_internal
instead of make_temp_name.
This incorporates:
2017-08-09 tempname: do not depend on secure_getenv
2017-08-08 extensions: add _OPENBSD_SOURCE
2017-08-06 manywarnings: Add support for C++
2017-08-06 warnings, manywarnings: Add support for multiple languages
* admin/merge-gnulib: Don't use m4/manywarnings-c++.m4.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/secure_getenv.c, m4/secure_getenv.m4: Remove.
* lib/tempname.c, m4/extensions.m4, m4/manywarnings.m4, m4/warnings.m4:
Copy from gnulib.
* admin/merge-gnulib (GNULIB_MODULES): Add d-type.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* m4/d-type.m4: New file, copied from gnulib.
* src/dired.c (DT_UNKNOWN, DT_DIR, DT_LINK)
[!HAVE_STRUCT_DIRENT_D_TYPE]: New constants.
(dirent_type): New function.
(file_name_completion): Use it, to avoid unnecessary calls to
stat-like functions on GNU/Linux and other platforms with d_type.
(file_name_completion_stat): Just follow the link; there is no
need to try first with AT_SYMLINK_NOFOLLOW since the directory
entry was already checked to exist.
* admin/merge-gnulib (GNULIB_MODULES): Add explicit_bzero.
* lib/explicit_bzero.c, m4/explicit_bzero.m4: New files.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/gnutls.c (clear_storage): New function.
(gnutls_symmetric_aead): Use it instead of memset.
Add a new command 'replace-buffer-contents' that uses the Myers diff
algorithm to non-destructively replace the accessible portion of the
current buffer. The Myers algorithm is implemented in Gnulib.
* src/editfns.c (Freplace_buffer_contents): New command.
(set_bit, bit_is_set, buffer_chars_equal): New helper functions.
(syms_of_editfns): Define new command.
* test/src/editfns-tests.el (replace-buffer-contents-1)
(replace-buffer-contents-2): New unit tests.

(styled_format): Use it instead of strtoumax. Use ptrdiff_t
instead of uintmax_t. Check for integer overflow.
* src/lread.c (LEAD_INT, DOT_CHAR, TRAIL_INT, E_EXP):
Move to private scope and make them enums.
(string_to_number): Compute integer value directly during
first pass instead of revisiting it with strtoumax later.
This incorporates:
2017-05-16 manywarnings: update for GCC 7
2017-05-15 sys_select: Avoid "was expanded before it was required"
* configure.ac (nw): Suppress GCC 7’s new -Wduplicated-branches and
-Wformat-overflow=2 options, due to too many false alarms.
* doc/misc/texinfo.tex, lib/strftime.c, m4/manywarnings.m4:
Copy from gnulib.
* m4/gnulib-comp.m4: Regenerate.
* src/coding.c (decode_coding_iso_2022):
Fix bug uncovered by -Wimplicit-fallthrough.
* src/conf_post.h (FALLTHROUGH): New macro.
Use it to mark all switch cases that fall through.

* src/gtkutil.c (xg_check_special_colors):
When using sprintf, don’t trust Gtk to output colors in [0, 1] range.
(xg_update_scrollbar_pos): Avoid use of possibly-uninitialized bool;
this bug was actually caught by Clang.
* src/search.c (boyer_moore):
Tell GCC that CHAR_BASE, if nonzero, must be a non-ASCII character.
* src/xterm.c (x_draw_glyphless_glyph_string_foreground):
Tell GCC that glyph->u.glyphless.ch must be a character.
