FASTCALL changes the calling convention.  Moves most of the parameters from 
the stack into registers, iirc.  If you're going to use it you need to at 
least mirror the attribute in the declaration in the header too (which I 
don't think the generator scripts do).  It's not a huge performance win last 
I checked.
