From 5dc268ed266a5209f7600441ffd6efdcc48d265c Mon Sep 17 00:00:00 2001
From: "Gregory P. Smith" <greg@krypto.org>
Date: Tue, 30 Apr 2013 00:03:01 -0700
Subject: [PATCH] * Fix remaining bits of issue 17192 for 3.3 - these changes  
 were missing from a messed up merge during the libffi 3.0.13   import.  the
 diffs from upstream libffi 3.0.13 are now small.
