OpenBSD treats strerror_r(0,,) as a success, but with a message
"Undefined error: 0"; while this is distinct from strerror_r(-1,,)
returning "Unknown error: -1", it does not imply success. Meanwhile,
if buf is short enough for ERANGE, then we can't use strstr to look
for "Unknown" or "Undefined" in the resulting message, like we had
been doing for strerror(). Fix this by shifting the burden - now
the strerror-override code guarantees that 0 will have an
override when needed.

MacOS X 10.5 strerror(0) is "Unknown error: 0", which is not distinguished
from "Unknown error: -1" for out-of-range. Worse, strerror_r(0,,)
is "Undefined error: 0", although strerror_r for all other out-of-range
values matches strerror.

Only strerror-override depends on winsock2.h; our strerror.c file
does not. This also fixes mingw strerror_r-posix use of winsock2.h
via strerror-override.
Since we assume C89 which guarantees a declaration for sterror, we
don't need to repeat that check.
* m4/strerror.m4 (gl_PREREQ_STRERROR): Delete.
* modules/strerror (configure.ac): No prereqs needed here...
* modules/strerror-override (configure.ac): ...but this needs it.

gl_cv_func_strerror_r_works if gl_FUNC_STRERROR_R_WORKS is not present.

Cygwin __xpg_strerror_r clobbers strerror, until cygwin 1.7.10; in
this case, we must replace strerror, but there was nothing in
strerror.m4 finding fault with cygwin's native strerror. Solve
this by splitting strerror_r.m4 into two parts, one for probing
for the strerror_r bug, and one for replacing strerror_r based
on the presence of bugs unrelated to signature issues; that way,
the 'strerror' module in isolation will not replace strerror, but
if strerror_r is in use for any other reason, then the two use
separate buffers.
Note that cygwin's strerror is thread-safe while the gnulib
replacement is not; but this is no worse than any other
platform where strerror is not thread-safe; in a single-threaded
program, the difference is not observable, and in a multi-threaded
program, you really shouldn't be using strerror in the first place.
Also note that this ends up replacing glibc 2.13 strerror as it
deems __xpg_strerror_r broken on that platform, which isn't
technically necessary for strerror, but doesn't hurt too much.
Meanwhile, glibc 2.14 fixed __xpg_strerror_r, and strerror is not
replaced in that scenario.
* m4/strerror_r.m4 (gl_FUNC_STRERROR_R): Split...
(gl_FUNC_STRERROR_R_WORKS): ...into new macro, to detect Cygwin
bug without replacing strerror_r.
* m4/strerror.m4 (gl_FUNC_STRERROR): Replace strerror if
strerror_r is buggy, but without requiring strerror_r compilation.
* doc/posix-functions/strerror_r.texi (strerror_r): Fix docs.

In the remaining files, convert to all-interval notation if
- there is already at least one year interval like 2000-2003
- the file is maintained by me
- the file is in lib/uni*/, where that style already prevails
Otherwise, use update-copyright's default.

* lib/strerror.c: Include <string.h> always, to test interface,
and to remove the need for the dummy.
Include intprops.h to compute width instead of doing it ourselves
and missing a CHAR_BIT declaration, which broke tar 1.19 on Solaris 8.
(strerror): Define it to return NULL if there's no system strerror.
(rpl_strerror): Use INT_STRLEN_BOUND to compute bound.
Omit !HAVE_STRERROR code. We don't need to worry about supporting
ancient pre-strerror Unix systems well any more. Saying "unknown
system error" is enough.
* lib/string.in.h (strerror): Simplify the ifdef to reflect the
simpler strerror.c implementation.
* m4/strerror.m4 (gl_FUNC_STRERROR_SEPARATE, gl_PREREQ_STDERROR):
Simplify the tests to reflect the simpler strerror implementation.
* modules/strerror (Depends-on): Add intprops.
