Yeah, I believe so. This is why glibc is under the LGPL.
It's really easy to create derived works under U.S. Law.
As a side note, there is some really interesting unexplored areas of law
relating to derivative works and things like dynamic vs. static linked
libraries. There is some case law, but I think it leaves a lot unanswered.
For the purposes of this discussion, I'm supporting the popular contention
that using a dynamically linked library creates a derivative work (although,
I have my doubts).
