Thanks a lot! I'll go through it, and see what needs to be applied to 
the CVS head. It's great that you got JIT & JIT3 to work. I'd like to 
get your changes in, and then look at Casey's patches for JIT & JIT3 
from this spring.

Thanks, I had to ask, since we'd like to prevent a situation where 
someone could pull an SCO on kaffe.

keep the nice patches coming :)
