* src/frame.c (tty_child_pos_param): Handle additional position
values.  New SIZE argument.
(tty_child_frame_rect): Process size before position.
(Fmake_terminal_frame): Do not store calculated size/position
values in parameters to avoid that a negative absolute position
is later interpreted as position relative to bottom/right edge
of parent.
(Fmodify_frame_parameters): For tty child frames process size
before position values so the latter can take a new size into
account.
* src/frame.h: Adjust declaration of tty_child_pos_param.
* src/gtkutil.c (xg_set_geometry): Handle negative frame
position specifications.
* src/msdos.c (IT_set_frame_parameters): For tty child frames
process size before position parameters.
* src/xfns.c (x_window): In the non-GTK toolkit variant leave
negative position values unchanged - the toolkit should know how
to handle them.  Process child frame position parameters
separately.  In the non-toolkit variant process child frame
parameters separately.

* src/window.c (last_mouse_window): New global var.  All static
instances removed, and all their uses replaced with this global
var.  This fixes a very unlikely bug where last_mouse_window was
GC’ed and a new window created in its place.  It also fixes several
places that assumed NIL_IS_ZERO without static_asserting it.
(init_window_once): Initialize the new var.

From a suggestion by Pip Cet.
* src/alloc.c (make_formatted_string): Omit first argument,
to simplify the calling convention.  All callers changed.
* src/doprnt.c (doprnt): Also support %u.  Update doc.

* src/comp.c (emit_limple_insn):
* src/msdos.c (dos_set_keyboard, dos_rawgetc):
* src/sysdep.c (convert_speed, list_system_processes):
* src/w32fns.c (deliver_wm_chars, Fx_file_dialog):
* src/w32term.c (record_event, w32_read_socket):
Prefer 'ARRAYELTS (x)' to 'sizeof x / sizeof *x'.

* admin/coccinelle/arrayelts.cocci: New file.

Run "TZ=UTC0 admin/update-copyright".

* src/conf_post.h (ENOTSUP): Define to ENOSYS as msdos.h once
did.
(IFTODT): Copy definition from Gnulib.

* src/dispnew.c (is_tty_frame): Also test FRAME_MSDOS_P.

* src/frame.c (tty_child_pos_param, tty_child_size_param):
Export functions.

* src/msdos.c (mouse_get_xy, mouse_moveto, mouse_pressed):
Offset mouse positions by those of the selected frame.
(it_face_override): New function.
(IT_set_face): New argument F.  Load FACE_ID from its face
cache.
(IT_write_glyphs): Track the frames on which glyphs were
generated and apply faces from their individual face caches.
(IT_write_glyphs_with_face): New function.
(tty_draw_row_with_mouse_face): Reimplement in line with tty.c
and eliminate an obsolete optimization.
(IT_clear_end_of_line, IT_clear_screen): Load faces from the
cache of the provided frame.
(IT_set_frame_parameters): Adjust frame geometry and garbage
frames after geometry parameters change as a child frame.
(BUILD_CHAR_GLYPH): Accept new parameter F.
(IT_menu_display): Offset cursor positions by those of the
selected frame.

* src/msdos.h (ENOTSUP): Move to conf_post.h for Gnulib.

* src/xdisp.c (redisplay_internal): Redisplay MSDOS frames
unconditionally as with terminal frames.

for such calls to intern.  This excludes only those symbols
which are interned and referenced only once during Emacs's
initialization, the timing of whose interning is
inconsequential, and symbols in w32.c, which would need to be
transferred to a new syms_of_w32 function that I cannot test.

Be more systematic about putting space before paren in calls,
and in avoiding unnecessary parentheses in macros.
This was partly inspired by my wading through gcc -E output
while debugging something else, and seeing too many parens.

This patch does not change the generated .o files on my platform.
