MinGW port - initial work uploaded

I've been working on a MinGW port for some time now. I've pushed out what I have so far to a git.git fork at repo.or.cz. For details on how and what to clone, please look at the top of

http://repo.or.cz/w/git/mingw.git

Thanks go to Johannes Schindelin for his initial work, which gave me quite a quick-start.

Status ------ So far I've used the tools only to run the test suite. According to that, all tools that are needed to manipulate a repository locally work.

clone, fetch, push does not work yet.

Contributions ------------- If you want to contribute, please consider using the mob branch in this repository. That branch is publically writable. Since I assume that contributions will not be too frequent, it should be ok that you push your patches there (without pulling it first), then notify me, and I download them before someone else overwrites them.
