The GPLv2 effectivly says "only under this license" because anything
used has to be compatible and you can't distribute your app with GPL
code that prevent others from releasing the entire program under the
GPL when redistributed later (without the owner of the code who is
releasing under not adding exceptions to the GPL that allow linking).

There isn't much presidence on the topic yet, but the GPLv3 seems to
allow mixing with code licensed under any compatible license according
to its terms and where the other license premits usage with other
licenses like the GPL.
