This is the same as 44c13eefe8 on
master. We should also remove this comment on the release branch,
otherwise it ends up in the emacs-module.h shipped to users.
* src/module-env-28.h: Remove maintainer comment.
* config.bat:
* msdos/sed1v2.inp:

MS-DOS.
* src/callproc.c (environ) [MSDOS]: New declaration.
(child_setup, emacs_spawn): Update MS-DOS parts for Emacs 28.
* src/fileio.c (Fcopy_file): Don't use copy_file_range on
MS-DOS.
* src/msdos.c (initialize_msdos_display): Add
`defined_color_hook'.
(openat, fchmodat, futimens, utimensat): New functions.
* src/msdos.h (FRAME_X_DISPLAY): New macro.
* src/process.c: Make some more things conditional on
subprocess support.

(open_channel_for_module): Avoid subprocess specific code
on MSDOS.
The C standard does not allow size-zero arrays, so redo struct
Lisp_Subr to not use size-zero arrays when native compilation is
not being used. Formerly, the code was using size-zero arrays (a
GNU C extension) to avoid using memory unnecessarily when
HAVE_NATIVE_COMP is not defined. Replace this hack with the
more-traditional hack of putting the relevant members inside
‘#ifdef HAVE_NATIVE_COMP’.
* src/alloc.c (cleanup_vector, mark_object):
* src/comp.c (make_subr):
* src/data.c (Fsubr_native_lambda_list, Fsubr_native_comp_unit):
* src/eval.c (init_eval_once, funcall_lambda):
* src/lisp.h (SUBR_NATIVE_COMPILEDP, SUBR_NATIVE_COMPILED_DYNP)
(SUBR_TYPE):
* src/lread.c (Fload):
Conditionally compile with ‘#ifdef HAVE_NATIVE_COMP’ instead of
with ‘if (NATIVE_COMP_FLAG)’. Redo members like native_comp_u[0]
to be plain native_comp_u. Put all uses of these members inside
‘#ifdef HAVE_NATIVE_COMP’.
* src/lisp.h (struct Lisp_Subr): Members native_comp_u,
native_c_name, lambda_list, type are now all ifdeffed out if
HAVE_NATIVE_COMP is not defined, instead of being size-zero
arrays. All uses changed.
* src/pdumper.c (dump_subr, dump_cold_native_subr)
(dump_do_dump_relocation):
* src/comp.h (NATIVE_COMP_FLAG): Remove; no longer needed.
* src/fileio.c (Fcopy_file): Work around a compiler bug in IBM XL
C for AIX, V12.1 (5765-J02, 5725-C72). Without this patch, the
compiler incorrectly complains “Initialization between types "int"
and "struct timespec" is not allowed” and “Initialization between
types "long" and "struct timespec" is not allowed”.
* src/editfns.c (Ftranspose_regions): Remove an obsolete comment about
memmove, following up to commit 72af86bd8c of 8 Jul 2010 by Andreas
Schwab and commit 354f9f0fc6 of 23 Feb 2016 by Fredrik Bergroth,
both of which added calls to memmove.
* src/xdisp.c (produce_stretch_glyph): Use the correct face for
non-ASCII characters. Support :relative-width display spec on
Lisp strings, not just on buffer text.
* src/w32inevt.c (do_mouse_event): Reset the 'mouse_moved' flag of
the selected frame. Without that, this flag might remain set on a
TTY frame that is not displayed.
* lisp/mouse.el (mouse-drag-track):
* lisp/mouse-drag.el (mouse-drag-drag): Set 'track-mouse' to some
value neither t nor nil.
* src/keyboard.c (make_lispy_position): If track_mouse is Qt,
report event on tool or tab bar (Bug#51794).
* src/callproc.c (emacs_spawn) <fork_done>: Define the label only
if USABLE_POSIX_SPAWN is defined, to avoid a compiler warning.
(cherry picked from commit a8fc080851)
posix_spawn is less error-prone than vfork + execve, and can make
better use of system-specific enhancements like 'clone' on Linux. Use
it if we don't need to configure a pseudoterminal.
Backported from commit a60053f836.
Unlike that commit, only define USABLE_POSIX_SPAWN on macOS, because
there posix_spawn is much faster than vfork.
Don't merge to master.
* configure.ac (HAVE_SPAWN_H, HAVE_POSIX_SPAWN)
(HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR)
(HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR_NP)
(HAVE_POSIX_SPAWNATTR_SETFLAGS, HAVE_DECL_POSIX_SPAWN_SETSID): New
configuration variables.
* src/callproc.c (USABLE_POSIX_SPAWN): New configuration macro.
(emacs_posix_spawn_init_actions)
(emacs_posix_spawn_init_attributes, emacs_posix_spawn_init): New
helper functions.
(emacs_spawn): Use posix_spawn if possible.
(cherry picked from commit a60053f836)
* src/coding.c (Fdecode_coding_region): Doc fix.
* doc/lispref/nonascii.texi (Coding System Basics)
(Explicit Encoding): Explain the significance of using 'undecided'
in 'decode-coding-*' functions.
* src/keyboard.c (Fposn_at_x_y): Clarify that the Y coordinate
includes the header-line and the tab-line. (Bug#51590)
* doc/lispref/windows.texi (Window Sizes, Splitting Windows)
(Textual Scrolling, Coordinates and Windows): Fix/remove improper
or confusing uses of "text area" of a window.
* src/nsterm.m (ns_init_locale): If not already set, set LC_ALL to the
current locale ID so that dates, currencies, etc. use the settings
configured in the operating system. (Bug#51321)
* src/dispnew.c (adjust_glyph_matrix, prepare_desired_row): Leave
room for the border glyph only if the window does actually have
the right margin. (Bug#51521)
Don't merge to master. This is a safe-for-release fix for Bug#50752.
* src/keymap.c (lookup_key_1): Factor out function from
Flookup_key.
(Flookup_key): Be case insensitive when looking for Qmenu_bar
items. (Bug#50752)
* test/src/keymap-tests.el
(keymap-lookup-key/mixed-case)
(keymap-lookup-key/mixed-case-multibyte): New tests.
When the mouse pointer is pressed on the tab bar, moved out of the tab
bar, and moved back in, it would be more appropriate to behave like
other programs by displaying the item as sunken.
* src/xdisp.c (note_tab_bar_highlight): Display item as sunken if the
mouse pointer returns to the tab bar down.
