There really is no licensing problem with the GPL and the TB code.
You only have to get permission from Eugene to include and redistribute
his code (you need that anyway) and grant an exception to link your
GPL code with Eugenes code.

The real issue is with freedom, i.e. Eugene's code is not free.
Since it is used as a library and is only a minor and removable
part of the chessengine I don't have much problems with that.

My real problem is that I'm simply not getting permission from
Eugene to redistribute his code. There isn't any license nor
exception that can deal with that...
