Here's an updated patch. The more I looked at the "struct type *type" 
argument, the less I understood about how it should be used. I assume it 
would only be used, so far, on i386, but I'm easily confused by stacks 
and registers (and how things are stored there), so any pointers would 
be appreciated.
