That depends on whether the code that links to the library is a
modification of that library or not. Which I understand to be a very
complex question about which there is very little clear jurisprudence.
Certainly no is the safe answer. But it might not be the _final_
answer. For example if you dynamically link, are you creating
something that is independent under copyright law? For example
suppose you wrap the code up in a web service then have another
program call the web service, is that OK?
There are a lot of ways to try to finesse the point. Certainly you
can find solutions that *might* stand up in a court. But before you
go with any of those solutions, you'll need to get legal advice from a
