A few days ago we (the Fedora MinGW SIG) started experimenting with generating -debuginfo subpackages for our libraries. For this we've created some custom scripts to strip out debug information to separate files and added some RPM macro's to create -debuginfo subpackages containing these files. This has been discussed at http://lists.fedoraproject.org/pipermail/fedora-mingw/2009-June/001748.html

The RPM scripts were added in mingw32-filesystem-52-1.fc12 and some of our regular MinGW packages were rebuild as can be seen at http://koji.fedoraproject.org/koji/buildinfo?buildID=111400

After waiting for the next rawhide push we discovered that the mingw32-glib2-debuginfo subpackage wasn't published in the rawhide-debuginfo repository. We think it's caused by the fact that our mingw32 packages are noarch.
