 src/w32.c (getwd): Adjust commentary about startup_dir.
 (init_environment): Always call sys_access, even in non-MSVC
 builds.  Don't chdir to the directory of the Emacs executable.
 This undoes code from 1997 which was justified by the need to
 "avoid conflicts when removing and renaming directories".  But its
 downside was that every relative file name was being interpreted
 relative to the directory of the Emacs executable, which can never
 be TRT.  In particular, it broke sys_access when called with
 relative file names.
 (sys_access): Map GetLastError to errno.

* src/window.h (struct window): Change type of 'fringes_outside_margins'

For some reason, this included an extraneous entry from the emacs-24
branch.

(describe-function-1): Refer to a function as "autoloaded" if it

GNUTLS_E_INTERRUPTED.

In the old days this wasn't portable, since some sprintf
implementations returned char *.  But they died out years ago and
Emacs already assumes sprintf returns int.
Similarly for float_to_string.
This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

* xfns.c (syms_of_xfns):
Use sprintf or float_to_string result to avoid need to call strlen.
* data.c (Fnumber_to_string):
Use make_unibyte_string, since the string must be ASCII.
* lisp.h, print.c (float_to_string): Now returns int length.
* term.c (produce_glyphless_glyph):
Use sprintf result rather than recomputing it.

strcasecmp and strncasecmp.

strcasecmp if available.

sprintf already null-terminates its output.

`const char *' to `char *' to avoid compiler warning.

instead of truncating it to 63 (admittedly a generous limit).
