Careful: the four-cluase BSD license (the one with the advertising
clause) is actually incompatible with the GPL. The incompatibility
is more with the GPL than the BSD license though, since the former
includes a clause that prohibits additional restrictions being put
on the code.
Although Berkeley and TNF (and from memory the other principal BSD
derivatives) have dropped the offending clause from _their_ licenses
there is still a lot of third party code in many BSD-licensed
packages that still contains the problematic clause.
