There is certainly nothing wrong with writing code like 'lo <= i
&& i <= hi', even if LO happens to a constant.  There isn't even
anything wrong in general with writing 'a <= b' if A happens to
be a constant.  At any rate stylistic changes shouldn't

Move the fallback definitions to dispextern.h.
* nsgui.h (XChar2b, STORE_XCHAR2B, XCHAR2B_BYTE1, XCHAR2B_BYTE2):
Likewise.  Share the same definition with W32.

... here for the consistency with W32 and NS.

Use "b" flag more consistently; avoid "t".

if it was "empty", or used for a different set of files.

Fixes: debbugs:17884

Use binary-io module, O_BINARY, and "b" flag.

* admin/merge-gnulib (GNULIB_MODULES): Add binary-io.  It was already
present implicitly; this just makes the dependence explicit.
* lib-src/etags.c, lib-src/hexl.c, lib-src/make-docfile.c:
Include binary-io.h instead of fcntl.h and/or io.h.
(main): Use set_binary_mode or SET_BINARY
in place of handcrafted code.
* lib-src/etags.c (main) [DOS_NT]:
* lib-src/movemail.c (main) [WINDOWSNT]:
Don't mess with _fmode.
* lib-src/etags.c (main, process_file_name, analyse_regex):
Use fopen/popen's "b" flag instead.

* src/sysdep.c, src/systty.h (emacs_get_tty): Return int, not void.
* src/sysdep.c (emacs_open, emacs_pipe): Use O_BINARY.
* src/w32.c (pipe2): Adjust eassert to include O_BINARY.

Fixes: debbugs:18006

* macros.c (Fstart_kbd_macro): Avoid need for overflow check.

* macros.c (Fstart_kbd_macro): Simplify.

This works around a GCC compiler bug when Emacs is configured with
--enable-gcc-warnings.

src/ChangeLog: Fix a typo in a recently added entry.

* term.c (tty_menu_add_pane, tty_menu_add_selection):
Use menu_item_width.
(tty_menu_show): Simplify because ty_menu_create never return NULL.

* lisp.h (CHECK_VECTOR_OR_STRING): Return number of elements
or characters in string, respectively.  Add comment.
* fringe.c (Fdefine_fringe_bitmap):
* fns.c (Fsubstring, substring_both): Use it.
* keymap.c (Fdefine_key, Flookup_key):
* macros.c (Fstart_kbd_macro): Likewise.  Avoid call to Flength.

* make-docfile.c: Simplify a bit, to simplify further refactoring.

(outfile): Remove static var.  All uses changed to use stdout,
since it's always stdout anyway.  While we're at it, prefer
putchar/puts/fputs to printf when there are no format strings.
(main): Use freopen rather than fopen, so that stdout is reused.
Move O_BINARY stuff after the freopen, so it affects the
reopened file.
(write_c_args): Omit first arg, since it's always stdout now.
All uses changed.

Improve behavior of 'bzr up; cd src; make -k'.

* Makefile.in (ACLOCAL_INPUTS): Add all m4/*.m4 files.
* src/Makefile.in (top_srcdir): New var.
(ntsource, lispsource, ALL_CFLAGS, gl-stamp, emacs.res):
Use '$(top_srcdir)' instead of '$(srcdir)/..';
its expansion is a bit shorter.
(../config.status): Actually build config.status instead of
just complaining.
(ACLOCAL_INPUTS, AUTOCONF_INPUTS):
New macros, copied and relocated from ../Makefile.in.
($(top_srcdir)/aclocal.m4, $(top_srcdir)/configure, config.in)
(../config.status, Makefile): New dependencies and rules,
copied with relocation from ../Makefile.in.  This should be more
likely to rebuild the build machinery properly if you do a 'make'
in the src directory.

Fix bug #17986 with infloop in redisplay when default-directory is nil.

 src/xdisp.c (decode_mode_spec): Call file-remote-p on the current
 buffer's default-directory only if it is a string.

 lisp/bindings.el (mode-line-remote): If default-directory is not a
 string, don't call file-remote-p on it; instead state in the
 help-echo that it is nil.

 etc/PROBLEMS: Mention the problem from bug #17950.

 src/w32fns.c (Fx_file_dialog): Mention in the doc string the
 behavior on Windows 7 and later when the function is repeatedly
 invoked with the same value of DIR.
 src/xfns.c (Fx_file_dialog) [USE_MOTIF, USE_GTK]: Update the doc
 string to match the one in w32fns.c.

* sysdep.c (emacs_get_tty, emacs_set_tty):
Move duplicate extern decls from here ...
