Without these changes, Emacs does not build on Fedora 26 x86-64
when configured --with-x-toolkit=no --enable-gcc-warnings.
* oldXMenu/Activate.c (XMenuActivate): Add FALLTHROUGH.
* src/xterm.c (x_dispatch_event): Define only if
USE_X_TOOLKIT || USE_MOTIF || USE_GTK.
Evidently nobody builds Emacs with --enable-checking=all,
which is no surprise as it is so slow as to be unusable nowadays.
Perhaps we should remove the slowest checks, or move them into
another category, or speed them up, or something.
* src/alloc.c (SDATA_SIZE) [GC_CHECK_STRING_BYTES]: Fix off-by-one
error in size calculation, which caused a failure when
--enable-checking=stringbytes was used. I introduced this bug in
2016-09-08T01:08:45!eggert@cs.ucla.edu "Port flexible array
members to GCC + valgrind".
* src/xdisp.c (should_produce_line_number) [USE_GTK]: Make sure
tip_frame is indeed a tooltip frame, before disabling line numbers
on it. (Bug#27647)
* src/dispextern.h (tip_frame): Add commentary describing the
kludgey usage of this variable in GTK builds.
* src/xdisp.c (try_window_reusing_current_matrix)
(try_cursor_movement): Disallow these optimizations if the buffer
has overlay arrow(s) shown on the fringe(s). (Bug#29198)
Apparently GCC requires that ‘__attribute__ ((aligned (8)))’ must
immediately follow the ‘struct’ keyword when aligning a structure.
The attribute silently does not work if it follows a tag after the
‘struct’ keyword. Who knew? Anyway, this patch is designed to
fix a SIGSEGV problem reported by John Mastro (Bug#29183).
* lib-src/make-docfile.c (close_emacs_globals):
* src/buffer.c (buffer_defaults, buffer_local_symbols):
* src/lisp.h (DEFUN):
* src/thread.c (main_thread):
Put 'GCALIGNED' immediately after 'struct'.
* doc/misc/emacs-gnutls.texi (Help For Users): Update the
documentation of 'gnutls-available-p'.
* etc/NEWS (GnuTLS): Mention the change in the value returned by
'gnutls-available-p'.
* src/gnutls.c (Fgnutls_available_p): Return non-nil when GnuTLS
2.x is available. (Bug#29147)
FreeBSD aarch64 does not provide sbrk, so gmalloc cannot be used; when
using system malloc dumping does not work correctly (allocated data is
invalid after dumping).
* configure.ac: Set hybrid_malloc for freebsd.
* src/gmalloc.c (gdefault_morecore) [!HAVE_SBRK]: Don't call sbrk.
* src/lisp.h (GCALIGNMENT): Change it back to a macro
that expands to a literal integer constant, for older GCC.
I had mistakenly thought that only MSVC had the problem.
Problem repored by Eli Zaretskii (Bug#29040#69).
Do not assume that the natural alignment of Lisp objects is a
multiple of GCALIGNMENT. This improves on the portability of the
recent fix for Bug#29040.
* lib-src/make-docfile.c (close_emacs_globals):
* src/buffer.c (buffer_defaults, buffer_local_symbols):
* src/lisp.h (DEFUN):
* src/thread.c (main_thread):
Use GCALIGNED, not alignas (GCALIGNMENT).
* src/alloc.c (COMMON_MULTIPLE):
Move back here from lisp.h, since it is no longer used elsewhere.
* src/lisp.h (GCALIGNMENT): No longer a macro, since we need not
worry about MSVC. Omit no-longer-needed consistency check.
* src/thread.c (THREAD_ALIGNMENT): Remove.
These fixes were suggested by Drew Adams.
* src/window.c (Fminibuffer_selected_window): Disambiguate
doc-string.
* doc/lispref/minibuf.texi (Intro to Minibuffers)
(Minibuffer Windows, Recursive Mini, Minibuffer Misc): Avoid
the term "currently active minibuffer window". Disambiguate
documentation of `minibuffer-selected-window'.
* src/lisp.h (COMMON_MULTIPLE): Move here from alloc.c.
* src/thread.c (THREAD_ALIGNMENT): New macro.
(main_thread): Use THREAD_ALIGNMENT to align propertly. (Bug#29040)
* src/fileio.c (Fset_default_file_modes): Doc fix. (Bug#28875)
* doc/lispref/files.texi (Changing Files): Clarify how the bits in
the argument of set-default-file-modes are used for setting file
permissions.
* src/doc.c (Fdocumentation): Restore the pre-25 behavior
of signalling a void-function error for an undefined function.
This seems cleaner than Emacs 25's "invalid-function: nil" error,
which was (probably) an unintended consequence of changes to
Findirect_function.
These changes also update the various bundled packages to use
new feature, and better support customizations of the line-number
face.
* src/xdisp.c (calc_pixel_width_or_height): Improve commentary.
Make :align-to count from the end of the line-number display when
the offset or the width form reference that of the text area.
(Bug#28855)
* src/indent.c (Fline_number_display_width): Implement support for
the PIXELWISE argument being 'columns'. Update the doc string.
(syms_of_indent): New symbol 'columns'.
* lisp/ruler-mode.el (ruler-mode-window-col, ruler-mode-ruler):
Call line-number-display-width with last argument 'columns'.
* lisp/proced.el (proced-header-line): Call
line-number-display-width with 2nd arg 'columns', which also fixes
a problem when display-line-numbers is nil.
* lisp/emacs-lisp/tabulated-list.el
(tabulated-list-line-number-width): Call line-number-display-width
with 2nd arg 'columns.
(tabulated-list-entry-lnum-width): Remove unneeded defvar.
(tabulated-list-print, tabulated-list-print-entry): No need to
account for the value of tabulated-list-entry-lnum-width.
(tabulated-list--current-lnum-width): New defvar.
(tabulated-list-watch-line-number-width): New function.
(tabulated-list-mode): Bind tabulated-list--current-lnum-width
locally, and set up tabulated-list-watch-line-number-width as
pre-redisplay-functions hook.
* doc/lispref/display.texi (Size of Displayed Text): Document the
'columns' value of the PIXELWISE argument.
(Pixel Specification): Update and improve the documentation of the
supported forms.
* msdos/sed1v2.inp (GETADDRINFO_A_LIBS, LIBLCMS2, XDBE_LIBS)
(XDBE_FLAGS, HYBRID_MALLOC, LIBSYSTEMD_CFLAGS)
(LIBSYSTEMD_LIBS): Edit to empty.
(LIBRESOLV, DEPFLAGS, MKDEPDIR, YMF_PASS_LDFLAGS)
(PRE_EDIT_LDFLAGS, POST_EDIT_LDFLAGS): Remove editing.
Remove editing of lines that are no longer present in
src/Makefile.in.
* msdos/sed2v2.inp (NEED_MKTIME_INTERNAL)
(NEED_MKTIME_WORKING): Define to 1.
(HAVE_STRUCT_DIRENT_D_TYPE): Define to 1 for
DJGPP >= 2.05.
(HAVE_STRUCT_ATTRIBUTE_ALIGNED): Define to 1.
Define PACKAGE_VERSION, not VERSION.
(FLEXIBLE_ARRAY_MEMBER): Define to empty.
(HAVE_DECL_*_UNLOCKED): Define to 0.
(HAVE___BUILTIN_FRAME_ADDRESS): Define to 1.
(PENDING_*): Don't define, as Gnulib no longer supports that.
Instead, define _IOERR as it is in libc/file.h.
* msdos/sed3v2.inp: Use $(CURDIR) instead of $(shell cd) to
determine the current directory.
(UPDATE_MANIFEST, UTILITIES): Don't edit.
* msdos/sedlisp.inp (FIND_DELETE): Edit to "-delete".
* msdos/sedlibmk.inp (AUTO_DEPEND): Define to yes.
(HYBRID_MALLOC): Edit to empty.
(am__cd): Don't edit.
(../config.status): Replaces $(top_builddir)/config.status.
Define OMIT_GNULIB_MODULE_foo = true for modules not built for
MS-DOS. Convert GL_GENERATE_xxx_H_TRUE and
GL_GENERATE_xxx_H_FALSE into values of GL_GENERATE_xxx_H.
* msdos/mainmake.v2 (src): Use 'compile-one-process', and make
the command line shorter to fit into 126-char limit of
command.com.
* config.bat: Generate src/deps/*.d files. Rename more files
like djtar on plain DOS would.
Don't rename src/dir.h: it is long gone. Edit
lib/gnulib.mk.in using the same scripts as for
lib/Makefile.in.
* msdos/depfiles.bat: Create *.d files, not *.Po.
* src/thread.c (Fmake_thread) [!THREADS_ENABLED]: Improve the
error message.
* src/thread.h [MSDOS]: Include <signal.h>.
* src/sysselect.h (select) [MSDOS]: Undefine, to avoid
compilation errors.

Expose to MSDOS build.
* src/process.c (update_processes_for_thread_death)
[!subprocess]: No-op implementation.
[HAVE_SETRLIMIT]: Move inclusion of sys/resource.h and
declaration of nofile_limit outside "#ifdef subprocesses", as
it's needed for MSDOS.
* src/msdos.c (faccessat): Declare fullname[].
* src/msdos.h (ENOTSUP): Define to be identical to ENOSYS.
Include termhooks.h.
* src/conf_post.h [WINDOWSNT]: Include ms-w32.h only on
WINDOWSNT, not DOS_NT.
* admin/admin.el (set-version): Set version on PACKAGE_VERSION.
* doc/lispref/os.texi (Time Parsing): Fix some errors in the
documentation for format-time-string. Document ^, #, %s, and %z
with colons. Say that unrecognized sequences are output as-is.
* src/editfns.c (Fformat_time_string): %S can stand for 60.
Also mention unrecognized sequences.
This should fix several bugs reported recently against Emacs
(Bug#28518, Bug#28626, Bug#28632, Bug#28633, Bug#28770).
* src/image.c (imagemagick_load_image):
Do not call MagickWandTerminus.
* src/indent.c (line_number_display_width): Make sure a line
number is generated even when the first line of the window is
completely hscrolled out of view. (Bug#28854)
Problem reported by Roland Winkler (Bug#28824#35).
Based on a patch proposed by Andy Moreton (Bug#28824#38).
* src/image.c (pbm_scan_index): New function.
(pbm_load): Use it to decode raw data correctly when its top bit
is set.
Make the effect of customizing arabic-shaper-ZWNJ-handling appear
immediately.
