From c5da3fd9ffd12402da719d5c4990b4e6b240d085 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Thu, 8 Oct 1998 12:19:48 +0000 Subject: [PATCH] (my_mktime_localtime_r): Renamed from localtime_r. Define also if HAVE_LOCALTIME_R && defined (localtime_r), with a body that merely expands localtime_r; this works around a bug in Digital Unix 4.0A and 4.0D. --- lib/mktime.c | 23 +++++++++++++++++------ 1 file changed, 17 insertions(+), 6 deletions(-) diff --git a/lib/mktime.c b/lib/mktime.c index 3803f5c74..0cf3a5f8d 100644 --- a/lib/mktime.c +++ b/lib/mktime.c @@ -127,22 +127,33 @@ time_t __mktime_internal __P ((struct tm *, #ifdef _LIBC # define localtime_r __localtime_r #else -# if !
