Please don't look for technical ways to try to circumvent the GPL.
Simply inserting some code that is covered by the LGPL in between code
that is covered by the GPL and code that uses some incompatible
license does not allow you to aovid the terms of the GPL.  If all the
parts are combined in a single work, the terms of the GPL must be
followed.

Instead of desparate measures to run non-free code in Octave, I think
it would be better to find ways to create free software that does the
job of the non-free code.  That way, the free softare community
benefits from the work.
