* 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.

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.
