	* strftime.c (strftime):
	When invoking self, check whether the subsidiary invocation failed.

	Make this source file portable to standalone contexts (e.g. GNU Emacs).
	<config.h>: Include if HAVE_CONFIG_H is defined.
	(HAVE_LIMITS_H, HAVE_MBLEN, HAVE_TM_ZONE, STDC_HEADERS): New symbols,

	<ansidecl.h>, "../locale/localeinfo.h": Include only if _LIBC.
	<sys/types.h>: New include; some hosts require it for `time_t'.

	(__P, PTR): Define if not already defined.
	(__tzname, __daylight, __timezone): Remove macros; no longer needed.
	(add, strftime): Don't use NULL, for portability to some weird hosts.
	(fmt): If !_LIBC, don't assume sprintf returns a count.
	(week, strftime): Use old-style function declarations.
	(weekday_name, month_name): New constants.
	(strftime): Use traditional C values if locale support isn't available.
	Use `const' instead of CONST.  For time zones, use tm_zone if
	possible, then fall back on tzname.  Don't check for multibyte
	characters unless mblen is supported.  Use formats like %02d instead
	of %.2d, for portability to older hosts.
