Recent clang and Python2.7 (without the patch):

Python 2.7.2+ (2.7:e8d8eb9e05fd, Sep 14 2011, 00:35:51) 
[GCC 4.2.1 Compatible Clang 3.0 (trunk 139637)] on freebsd8
Type "help", "copyright", "credits" or "license" for more information.

The patch is fine and I'm going to commit it tomorrow if there are no
objections.
