The FSF's interpretation of the GPL is that you cannot use (even by
linking) a GPL'd library in a non-GPL-compatible work. Whether this is
also the legal meaning of the license is widely and hotly disputed; I
recommend you to obtain the advice of an intellectual property lawyer if
you want a reliable opinion. I don't consider any of the various
non-lawyer opinions that you'll find floating around the net to be
reliable, including mine or the FSF's.
It is clear at least to me from other subsequent statements that it was
the intention of the authors of the GPL to prohibit this use of GPL'd
code. See, for example:

Given that the question is about one of their licenses, licensing at gnu.org
would be the best place to get the official GNU position on this point.
