Gammu and Wammu are looking for maintainer of Windows build. You have great opportunity to help this project.
As you might have noticed, Gammu 1.26.91 has been released without Windows binaries for Python bindings. The reason is simple - my cross compilation setup broke again and I don't have time to fix it. Cross building Python extensions was always tricky, but it is getting harder and harder with each Python version - it requires newer MSVC support libraries to link with and it introduces various complications.
Doing that natively on Windows, should not be that hard. You need to have Visual Studio and you need some experiences with building things for Windows. If you want to help, just contact us on mailing list.
