From a8730cf0211afa45915dc13a7bad715f4496d03e Mon Sep 17 00:00:00 2001
From: kouril <kouril>
Date: Mon, 16 Aug 2004 13:20:53 +0000
Subject: [PATCH] Added changes to enable compiling on Windows (most likely not
 sufficient) - Added standard includes - use {_vs,_s}nprintf instead of
 {vs,s}nprintf - added implementation of the mkstemp() call (taken from
 heimdal)
