Since the files have a license at the top of them, I think it's safe
to say that is their license. As for newMain.c, that's probably GPL.

Dynamically linking Ispell with LGPL'd software is fine. Statically -
I'm not sure.

And in many cases illegally :-(. Look at the mess AbiWord has now.

That's definately incompatible with the GPL, and I doubt it works with
the LGPL either. You may be able to get by with it, but it's ugly and
pollutes the licensing of the code.

Perhaps Atkinson could make an exception in the pspell license to
explicitly allow loading dynamic modules under any license. This is
what Linux does, to the horror of RMS. It may be too late for Atkinson
to change his licensing, though.
