It seems there is an off by one error with the "warning: unused variable" warning.
There are many off by one [token] problems with messages. I think I know how to fix them now, but it will require a new Bison version. Even worse, it seems to require a Bison bugfix first, and I don't know how long this will take. So it might get even somewhat worse in the next GPC release, but hopefully correct some time later ...
