* 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.
