The only restriction the GPL places on the code is that if you  
distribute GPL'ed software, you also have to distribute the source.   
That's the only restriction.  The license is infectious, so if you  
build something that uses some GPL'ed code, you have to release your  
code using the GPL too.

But in the case of FFTease, you could release it under a MIT or BSD  
license, both of which let anyone do anything with it with minor  
restrictions:  both require that the copyright notice is always  
distributed with any software that uses the code, and the BSD license  
requires that you get written permission before using the name of the  
software/copyright owner.  Both of these are completely compatible with  
the GPL.  You could also put it in the public domain, then anyone could  
do anything with it, regardless.

It order for FFTease to be included in Pd-extended, it would have to  
use a GPL-compatible license.
