In this case I think it should be made clear that parts of Plplot are not
LGPL but under a less constrained license.  Such a statement should be
added to the toplevel Readme/license.terms of Plplot.

Both of these cases I think you have to contact the author and ask.  Just
because I don't attach a copyright notice to a piece of code doesn't mean
I am automatically giving up all my rights to it!
