From 35bd81e535416d38acc03cda06d72f3f3e32b596 Mon Sep 17 00:00:00 2001
From: Vincent Torri <vincent.torri@gmail.com>
Date: Mon, 2 Nov 2009 08:41:43 +0000
Subject: [PATCH]  * add amalgamation option to eet (disabled by default,    as
 no real gain is seen (compilation time, size))  * add namespace for
 words_bigendian, to make amalagamation happy  * don't redefine macros, for
 the same purpose
