I could be wrong, but I believe that Brian's intention is indeed to
release a commercial/proprietary app, hence it is possibly an issue for
him. I'm not sure about having to distribute the code for his app; I
thought the point of the LGPL license was to allow proprietary
(non-GPL?) apps to link to LGPL libs. Wouldn't he just have to
distribute the code for GMP? But then, I understand less about FSF
licensing than pretty much everyone else on this list, so I'll shut up
now...
