* 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

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

* src/msdos.c (faccessat):
* src/w32.c (faccessat): Support relative file names, and add D_OK
to 'mode' if the argument is a directory.  This unbreaks file-name
completion when the completion result is a directory.

moved to etc/NEWS.

* src/dispextern.h (FACE_FROM_ID_OR_NULL): Renamed from
FACE_OPT_FROM_ID; all callers changed.
* src/xdisp.c (extend_face_to_end_of_line): Call FACE_FROM_ID, not
FACE_FROM_ID_OR_NULL, as the resulting face is immediately
dereferenced.
(fill_gstring_glyph_string): Call FACE_FROM_ID, not
FACE_FROM_ID_OR_NULL, as the resulting face will be dereferenced
when the glyph string is drawn.
(BUILD_COMPOSITE_GLYPH_STRING): Call FACE_FROM_ID, not
FACE_FROM_ID_OR_NULL, as the resulting face will be dereferenced
in fill_composite_glyph_string.
(calc_line_height_property): Call FACE_FROM_ID_OR_NULL rather that
FACE_FROM_ID, since the function and its caller can cope with that
situation.  Conflate 3 tests of missing face or font into just
one.
* src/xfaces.c (Fx_list_fonts, Fface_font, lookup_face): Call
FACE_FROM_ID_OR_NULL rather that FACE_FROM_ID, since these
functions can cope with that situation.
(lookup_derived_face): Don't call FACE_FROM_ID if the result will
not be used.

Redo loop to convince GCC 6.1 that it is null pointer safe.
(x_color_cells):
Use eassume as necessary to pacify GCC 6.1.
* src/dispextern.h (FACE_FROM_ID, IMAGE_FROM_ID): Now returns non-null.
(FACE_OPT_FROM_ID, IMAGE_OPT_FROM_ID): New macro, with the old
behavior of the non-_OPT macro, to be used when the result
might be a null pointer.

[HAVE_WINDOW_SYSTEM]:

* src/keyboard.c (read_char): Suppress bogus -Wclobbered warning.
* src/process.c (would_block): New function.
(server_accept_connection, wait_reading_process_output, send_process):

* msdos/sed3v2.inp:
* msdos/sed2v2.inp:
* msdos/sed1v2.inp: Adapt to Emacs 25.

* src/process.c (remove_slash_colon): Move out of "#ifdef
subprocesses" block, as it its called unconditionally.  Move
ADD_SUBFEATURE calls into "#ifdef subprocesses" block, as they
reference variables only defined in that block.
* src/msdos.h: Provide prototypes for IT_set_frame_parameters,
faccessat, msdos_fatal_signal, syms_of_msdos, pthread_sigmask,
dos_keysns, dos_keyread, run_msdos_command, and
syms_of_win16select, to avoid compiler warnings.
* src/msdos.c (SYS_ENVIRON): Define to either '_environ' or
'environ', depending on the DJGPP version.
Remove declarations of externally-visible Lisp objects, like
Qbackground_color and Qreverse.
(run_msdos_command): First argument is not signed, not unsigned.
Use SYS_ENVIRON.
(sys_select): Use 'timespec_cmp' instead of 'timespec_sign', as
the latter doesn't work when 'time_t' is an unsigned data type.
This caused idle timers to behave incorrectly: they only fired
after a keyboard input event.
* src/frame.c (adjust_frame_size) [MSDOS]: Account for
FRAME_TOP_MARGIN that isn't counted in the frame's number of
lines, but dos_set_window_size needs it to be added.
* src/lread.c (INFINITY, NAN) [DJGPP < 2.05]: Provide definitions.
* src/fns.c (sort_vector_copy) [__GNUC__ < 4]: Provide a prototype
that works around compilation errors with older GCC versions.
* src/w16select.c: Don't declare QCLIPBOARD and QPRIMARY as Lisp
Objects.
* src/filelock.c [MSDOS]: Ifdef away most of the code.  Provide
no-op implementations for 'lock_file' and 'unlock_file'.
(Ffile_locked_p) [MSDOS]: Always return nil.  This avoids multiple
ifdefs in all users of filelock.c functionality.
* src/conf_post.h (EOVERFLOW, SIZE_MAX) [DJGPP < 2.04]: Define.
* src/emacs.c [MSDOS]: Include dosfns.h, to avoid compiler
warnings.
* src/dosfns.h: Provide prototypes for dos_cleanup,
syms_of_dosfns, and init_dosfns.
* src/deps.mk (atimer.o): Depend on msdos.h.
(emacs.o): Depend on dosfns.h.
* src/atimer.c [MSDOS]: Include msdos.h, to avoid compiler
warnings.

* lisp/window.el (window--adjust-process-windows): Skip the body
if 'process-list' is not available.  This avoids failure to start
up on MS-DOS.
* lisp/vc/diff.el (diff-no-select): Test 'make-process', not
'start-process', as the latter is now available on all platforms.
* lisp/textmodes/ispell.el (ispell-async-processp): Replace
'start-process' with 'make-process' in a comment.
* lisp/term/internal.el (IT-unicode-translations): Modify and add
a few translations to display Info files with Unicode markup.  Fix
an ancient off-by-one mismatch error with Unicode codepoints.
* lisp/progmodes/compile.el (compilation-start): Test
'make-process', not 'start-process', as the latter is now
available on all platforms.
* lisp/man.el (Man-build-man-command, Man-getpage-in-background):
Test 'make-process', not 'start-process', as the latter is now
available on all platforms.
* lisp/international/mule-cmds.el (set-coding-system-map): Test
'make-process', not 'start-process', as the latter is now
available on all platforms.
* lisp/eshell/esh-cmd.el (eshell-do-pipelines-synchronously): Doc
fix.
(eshell-execute-pipeline): Test 'make-process', not
'start-process', as the latter is now available on all platforms.

Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function.  This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.

Run admin/update-copyright.

* xfaces.c (face_change): Rename from face_change_count, and
change from int to bool.  The var is now true (instead of nonzero)
if attributes have changed; this is simpler.  All uses changed.
Fixes: bug#19698

Especially, C99 prohibits nesting a struct X inside struct Y if
struct X has a flexible array member.
Also, merge from gnulib, incorporating:
2013-11-03 intprops: port to Oracle Studio c99
* lib/intprops.h: Update from gnulib.
* src/alloc.c (struct sdata): New type.
(sdata): Implement in terms of struct sdata.
Remove u member; all uses replaced by next_vector, set_next_vector.
(SDATA_SELECTOR, SDATA_DATA, SDATA_DATA_OFFSET): Adjust to sdata change.
(SDATA_DATA_OFFSET): Now a constant, not a macro.
(struct sblock): Rename first_data member to data, which is now
a flexible array member.  All uses changed.
(next_vector, set_next_vector, large_vector_vec): New functions.
(vector_alignment): New constant.
(roundup_size): Make it a multiple of ALIGNOF_STRUCT_LISP_VECTOR, too.
(struct large-vector): Now merely a NEXT member, since the old approach
ran afoul of stricter C99.  All uses changed to use
large_vector_vec or large_vector_offset.
(large_vector_offset): New constant.
* src/dispnew.c: Include tparam.h, for tgetent.
Do not include term.h; no longer needed.
* src/gnutls.c (Fgnutls_boot): Don't continue after calling a _Noreturn.
* src/lisp.h (ENUM_BF) [__SUNPRO_C && __STDC__]: Use unsigned int.
(struct Lisp_Vector): Use a flexible array member for contents,
instead of a union with a member that is an array of size 1.
All uses changed.
(ALIGNOF_STRUCT_LISP_VECTOR): New constant, to make up for the
fact that the struct no longer contains a union.
(struct Lisp_Misc_Any, struct Lisp_Marker, struct Lisp_Overlay)
(struct Lisp_Save_Value, struct Lisp_Free):
Use unsigned, not int, for spacers, to avoid c99 warning.
(union specbinding): Use unsigned, not bool, for bitfield, as
bool is not portable to pre-C99 hosts.

This helps to avoid a few glitches dictated by C's aliasing rules.
* lisp.h (struct Lisp_Vector): Use union for next and
contents member.  Adjust comment.  Change related users.
* alloc.c (next_in_free_list, set_next_in_free_list): Remove.
Related users changed.
* buffer.c, bytecode.c, ccl.c, character.h, chartab.c, composite.c:
