I'm all for polishing, and I'd love to see a powerpc port too.

If people want to go off and write another compiler, feel free.  It seems to 
be a popular activity:

Personally, I'd rather work on tcc...

Patches welcome. :)

Right now I'm trying to get it to build software I have lying around.  I'm all 
for cleanups but before I personally do too much more of them I want to 
become way more familiar with the code first.  I can't clean it up if I don't
