I haven't read the cc65 licenses very carefully, but if they are compatible 
with the GPL, there shoud be no problems in linking GPL code with them. (The 
original cc65 copyright license isn't compatible with the GPL, though, 
because it says that "You don't charge anything for the copy.")

Think of the cc65 libraries as the module that is to be added to a 
GPL-covered module, then the FAQ answer makes more sense in this particular 
situation. The answer says "But you can give additional permission for the 
use of your code. You can, if you wish, release your program under a license 
which is more lax than the GPL but compatible with the GPL." In this case, 
the cc65 library (which is refered to as "your code" in the above answer) 
license is more lax than the GPL. As long as it is compatible with the GPL, 
there are no problems.

Anyway, this is how I interpret the GNU homepage and FAQs. But when it comes 
to the interpretation of the actual GPL text, I'll gratefully leave that to 
the lawyers ;-)
