> Please forgive my ignorance, but what's wrong exactly in licensing > under only a single version of the GPL? That creates a license incompatibility. GPL 2 and GPL 3 are incompatible licenses. For instance, suppose you want to merge code from Linux (released under GPL 2 only) with code from GCC (released under GPL 3 or later). There is no lawful way to do it. GPL 2 and GPL 3 have requirements that conflict, so there is no way to satisfy them both. If Linux were released under "GPL 2 or later", there would be no incompatibility; merging code from Linux with code from GCC (or any other program under "GPL 3 or later") would be possible.
