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
be done like this without discussion.

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]:

* 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.

* lisp.h (CHECK_VECTOR_OR_STRING): Return number of elements
or characters in string, respectively.  Add comment.

* 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.

(ntsource, lispsource, ALL_CFLAGS, gl-stamp, emacs.res):

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
