The GPL text I have here says, in section 2

    b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

This *might* be interpreted to mean that I'm allowed to paraphrase
what the GPL says (but I would not bet on either RMS or a court
agreeing with that interpretation).

But the IBM license only allows changing the license for *object code*
redistribution, which is not what the GPL asks. And the IBM license
itself does quite obviously not pass as a paraphrase of the GPL.
