Mon Sep 18 12:39:22 1995 Paul Eggert <eggert@twinsun.com>
	* mktime.c (localtime_r): Add substitute if the system doesn't
	provide one.

Mon Sep 18 14:39:20 1995  Roland McGrath  <roland@churchy.gnu.ai.mit.edu>

	* time/gmtime.c (gmtime_r): Define as weak alias.
	* time/localtime.c (localtime_r): Define as weak alias.
	* time/time.h [__USE_REENTRANT] (gmtime_r, localtime_r): Declare them.

	* errno.h: Only define _ERRNO_H #ifndef __need_Emath.
	#undef __need_Emath after including errnos.h.
	[_ERRNO_H]: Protect decls with this.

Sun Sep 17 08:22:12 1995  Paul Eggert  <eggert@twinsun.com>

	Fix mktime so that it does not write over localtime's returned value.
	* localtime.c (__localtime_r): New function, with extra arg
	specifying where to store result.
	(localtime): Use it.
	(_tmbuf): New var.
	* gmtime.c (__gmtime_r, gmtime, _tmbuf): Likewise.
	* mktime.c (__mktime_internal):	Conversion function is now
	__localtime_r style, not localtime style.
	(mktime): Pass __localtime_r, not localtime.
	* timegm.c (timegm): Pass __gmtime_r, not gmtime.
	* offtime.c (__offtime): New arg specifying where to store result.
	* time.h (__mktime_internal, __offtime): Adjust decls accordingly.
	(__gmtime_r, __localtime_r): New decls.

	* time/localtime.c: <stddef.h>, <ctype.h>, <stdio.h>,
	<stdlib.h>, <string.h>: Remove includes.
	<errno.h>: Add include.

	* time/mktime.c, time/time.h, time/timegm.c (__mktime_internal):
	Renamed from _mktime_internal to avoid namespace pollution.

	* time/gmtime.c: Clear tm_isdst.

	* misc/efgcvt_r.c (ecvt_r, fcvt_r): Last arg is size_t, not int.
	* stdlib/stdlib.h (ecvt_r, fcvt_r): Fix type of last arg: make it
	size_t.

	* sysdeps/mach/hurd/fpathconf.c: Call __io_pathconf instead of
	__file_pathconf.
	* sysdeps/mach/hurd/pathconf.c: Likewise.
