Oops, sorry, I'm afraid I'm so crufty in my coding style these days I 
just automatically follow my internal conventions.

It would be helpful, mostly to prevent problems with future coding 
diverging from the core.  I build everything on a machine that has the 
patched version, so I don't *need* it, but better safe than sorry I 
suppose.  Basically if you have the time it would be great, if not it 
will probably be a few weeks before I get around to testing with the 
un-sub-classed versions.

One of the libraries I was wrapping (GLX? GLE?) defined them and since 
they were considered fundamental types they were causing the whole 
generator to fail (IIRC).  It's probably not critical to support them, 
but they at least shouldn't cause a failure in the generator.  Not sure 
what to do when we encounter one if they aren't supported, maybe just 
abort the whole function?  The complex types are probably from 
quaternion code somewhere, which is one of the few places complex 
numbers show up in 3d graphics, btw.

Have fun,
Mike
