It looked like it was mostly whitespace errors or somesuch. The patch
algorythm couldn't find the are to patch.
... however, as I said... I was able to patch it by hand.

Andre> Do you enable "link1" on your GRE interface?
What does link1 do to gre? It hasn't been necessary before.
Andre> What does ifconfig -a show?
Ifconfig -a output was normal. I didn't save the new output, but the
old output is the same ... save the fact that the new output prints
the tunnel endpoints.
