It depends on what you mean.  Can you hike off the author's license and
impose your own?  No, you can't do that, by both law and custom.
Only the author gets to decide the license of a piece of code.

Can you use the program to create a derivative work which you license under
the GPL?  Yes, absolutely, as long as you keep the above license attached
to its component and make clear that the GPL applies to the program
as a whole.  It's commonplace to do so.

To say that Bilbo's breath was taken away is no description at all.  There
are no words left to express his staggerment, since Men changed the language
that they learned of elves in the days when all the world was wonderful.
