From 4960863be275c4c21ef281c96836dfbf12bbd0f4 Mon Sep 17 00:00:00 2001
From: Amar Takhar <verm@aegisub.org>
Date: Sun, 22 Feb 2009 05:38:46 +0000
Subject: [PATCH] Add --enable-gcov, --enable-efence and --enable-ccmalloc for
 gcov, Electric Fence and ccmalloc support.  gcov support won't work without
 manual intervention (for now) but some hooks will be added later to automate
 it.

Originally committed to SVN as r2745.
