Martin, I think the cleanest solution that respects all parties would
be to remove the GPL code from your distribution, put that code in the
Maxima code base, and distribute a plugin that offers to fetch the
code from Maxima's Sourceforge site (under its license). When the next
Maxima release comes, you could change that to offer to install the
latest version of Maxima which will come with enhancements for SMath.

Does that seem reasonable?

Leo
