Choice of license is a headache for many people, including me.
I'm very interested in understanding the reasons why LGPL would be a "limit" for your needs.
Do you intend to modify GMP and not share ? Or do you need that your users can do that ?

Same question for Jan :

What interpretation of the license makes it a problem to consider compiling any software with GMP ?

I believe such explanation would also be of great interest for other people.

But others may behave differently, as Torbjörn mentioned.
