Software doesn't have to be under one license only, it can have
multiple licences. And that's what happens here.

Of course, the whole program will be under the GPL. That's what the
GPL requires. But that doesn't prevent someone from saying that all
the lines of codes they added to the program can be used under the BSD
license. So, in fact, those lines of code are than licensed under both
the GPL and the BSD license.

And for even smaller number of projects, BSD-style is better (ogg
vorbis for example). :-)
