[No, I'm not interested in the port myself]
patches for a mingw32 port are floating around on the web and the python bug tracker, although most of them as a set of patches in one issue addressing several things, and which maybe outdated for the trunk. at least for me re-reading a big patch in a new version is more work than having the patches in different issues. So proposing to break down the patches in independent ones, dealing with:
mingw32 support (excluding any cross-build support). tested with a native build with srcdir == builddir. The changes for distutils mingw32 support should be a separate patch. Who could review these? Asked Martin, but didn't get a reply yet.
patches to cross-build for mingw32.
patches to deal with a srcdir != builddir configuration, where the srcdir is read-only (please don't mix with the cross-build support).
All work should be done on the tip/trunk.
So ok to close issue16526, issue3871, issue3754 and suggest in the reports to start over with more granular changes?
