Or does the GPLv3 say anything compiled with gcc becomes GPLed?

Bull fucking shit, man -- this would only hit Novell if it tries to stick to that Anti-GPL patent scam it [cooked up with | got suckered into by] Microsoft. (Just like the GPLv3 anti-Tivoization provisions wouldn't hit anybody but Tivo and those who, like they, try to lock away their code from the user.) Nobody else; and not even them, if they'd just stop trying to circumvent the original spirit of the GPL.

P.S: "Version 1.2 or any later ..."? ITYM "2", right?
