It may well be commercial (we have nothing against that) but the
source code must be provided. It would be interesting to know where
the "No valid licence" message was coming from. If it's in the
compiler, it should simply be a matter of liiking in the source code
to see. If the message is in the compiler, but not in the source code
that is provided for the compiler, then that is a GPL violation.
