I have a version of GRX for mingw32 here, but I am waiting with a release until (a) some license issues are solved and (b) we have found someone to merge and maintain the source, so GRX can become an official GNU project.
To all (again): This is a great chance to become an official GNU maintainer!
Peter, we still need Ulrich Leodolter for the license change. We could start without his agreement and add the X11 driver back in later.
If this is appropriate, we should start now. IŽll get more and more busy with other tasks in future and I want to assign GRX to the FSF as soon as possible.
