From 7683e1407806ece4c6927866587c3359ee247f7d Mon Sep 17 00:00:00 2001
From: Roland McGrath <roland@gnu.org>

Subject: * time/mktime.c: (my_mktime_localtime_r):

	Remove.  All uses changed to __localtime_r.
	(__localtime_r) [!defined _LIBC]: New macro.  Include "time_r.h" to
	get its implementation.
	Fix compile-command to allow for TIME_R_POSIX.

	* time/strftime.c (my_strftime_gmtime_r, my_strftime_localtime_r):
	Remove.  All uses changed to __localtime_r and __gmtime_r.
	(__gmtime_r, __localtime_r) [!HAVE_TM_GMTOFF]: New macros.
	Include "time_r.h" to get their implementations.

	* time/timegm.c: Allow use in GNU applications outside glibc.
	[defined HAVE_CONFIG_H]: Include <config.h>.
	[!defined _LIBC]: Include "timegm.h", <time_r.h>.
	Define __gmtime_r, and declare __mktime_internal.
	(timegm): Define via a prototype, since we can safely assume C89 now.
