Well, there is a distinction between software that is GNU and software that
is used in the GNU system. So, a GNU system includes X, which is obviously
not copyrighted by FSF (not even GPL).
There are even cases where parts of GNU software contain code not
copyrighted by the GPL (thanks to Gunnar Evermann for pointing out an
example in emacs).
But rest assured that the FSF is very eager to get the copyright assigned to
them, and incorporating parts which are not is an exception usually (I say
this from my experience).
Thanks for the correction,
