From 8e664dd105723c607baf4e1ee7f690bdbc1febc1 Mon Sep 17 00:00:00 2001
From: Pierre Joye <pajoye@php.net>
Date: Mon, 28 May 2007 17:57:20 +0000
Subject: [PATCH] - enable tests even when an external GD is used. Latest
 releases   (2.0.34 or 2.0.35) work.   NB: if you use Debian, you'll realize
 how bad their package is and start   to either use the source or push all
 patches I posted to their bugs   tracker
