If you have klibc installed ("make install" or equivalent), you should 
be able to use the "klcc" wrapper script to gcc.  It takes pretty much 
the same parameters as gcc.

3.0 is quite ancient; I'm not sure something that old will work.  3.2.3 
I think it's the oldest one I've tried.

I should probably set up a klibc wiki.  I can get a wiki set up, but 
getting help populating it would be highly appreciated.
