That pragma was removed before the release. I am setting up the new
processor files now.

I am adding the interrupt support in 0.12.1. You can do it now, but
again it requires mixing assembly and pal code.

I have made many improvements in gputils. Some are in CVS. I will
commit more changes over the next few days. I hope to release 0.12.1
shortly after that.
