The current source code repository for the MinGW runtime is at: http://sourceforge.net/p/mingw/mingw-org-wsl/ci/21762bb4a1bd0c88c38eead03f59e8d994349e83/tree/
It has changed a lot since 3.20 and in fact rolls in win32api too. Both of these will be released as one package and the next version to be released will be 4.00 - so I expect this will not be as simple as a quick MinGW Runtime compile and we're good to go. But I'll give it a go and see what new things we find. Best Regards, Brian.
