License terms for ITERATE

[Robert P. Goldman]

ITERATE has a GPL license.  Does that mean that the developers intend
that any system using ITERATE must, itself, be GPL?

I am not certain what follows from GPL licensing, since Lisp code isn't
linked with library code. But I fear it might, or might require some
cumbersome expedient like forcing people who distribute non-GPL code to
hand off the ITERATE code and require recipients to compile it in
themselves.

Is there any chance that this could be offered under LLGPL or some
less-restrictive license?

Thanks,
