"Compatible" means "works together". The BSD licence is as much GPL-
compatible as the GPL is BSD-compatible.

You can never relicence other people's code. The GPL doesn't allow you
to do that either - so, I don't think you're right to call the GPL
"infecting". If you combine two pieces of software that are licenced
differently, you must fulfil the obligations of *both* simultaneously:
you must respect the BSD licence as much as the GPL.
