Hi Tim!

thanks for the quick reply. I've actually got the problem with 
ppc-linux-jit3 now, too. jitBasic dies as soon as the generated code is 
invoked in the first test :(

In order to get familiar with the jit3/ppc setup i thought about porting 
the mnemonicizer setup to x86. Does that souind like a useful idea?

ah! xdebugging works with ppc?
