Yes, you're right, of course. Explanations here:

        http://www.gnu.org/licenses/gpl-faq.html#GPLIncompatibleLibs
        http://www.gnu.org/licenses/gpl-faq.html#FSWithNFLibs
        
(In short, you have to add a special notice to the copyright notice or 
GPL text, if your program links with non-GPLed stuff that is not part 
of the OS or development system.)


Wonder how many GPLed applications actually do that. I've seen a few 
that use non-OS non-GPL stuff (many using FMOD, for example), but I 
can't remember seeing any special exceptions for that anywhere...
