Wow! Thanks for the feedback.
Well, if there are people who use the port, I'm happy to continue
working on. For me it was enough at that time so I didn't continue in
the public. I have some pending stuff for altivec which I need to back
out and then I try to tackle the threads issue. I was not aware of.
After fixing this I resubmit and I hope a porter will catch up my work
and hopefully commit it to the ports tree.
Thanks again.
Andreas
