Hello Helmut, I am not sure whether reassigning the bug to mingw-w64-tools is the best way to get a quick (intermediate) solution. If it helps, I have no objection, although I thought that patching the pkg-config package would be easier to fix that special issue.
I agree that a Debian architecture *-w64-mingw32 would be the preferred solution, but that will take much more time. Nevertheless I am willing to try that (with your help) and see how how far we can come with reasonable efforts. Stefan CC'ing Steven
