You are right, however, adding the exception ("you can link to closed-source") *might* make the "modified" license incompatible with the GPL, meaning if we allow the exception, then we cannot link to GPL'd plugins anymore (ie. we couldn't use FFTW anymore). Of course, I'm not sure of that and that's why I asked RMS about it. Jean-Marc -- Jean-Marc Valin Universite de Sherbrooke - Genie Electrique valj01 at gel.usherb.ca
