Turns out it's easy - the GNU runtime uses class names, not class  
pointers.  I was missing an objc_get_class() reading the code.

Attached diff fixes this, should fix it on 64-bit platforms (untested  
- I don't have a machine to try it on), and removes two FIXMEs that I  
forgot to remove before sending the last patch.
