Hi Eric,

thanks a lot for the new port!

Thank you, checked in.

Yeah, with pthreads you don't need the SP_OFFSET stuff. Checked in.

Thanks again, checked in as well.

In theory kaffe from CVS should default to use pthreads. In practice, 
that seems to have failed on your system. Could you post the relevant 
bits from config.log and what you set PTHREADS_LIBS to in order to make 
it work?
