I've updated the MinGW port at
pull/clone: git://repo.or.cz/git/mingw.git gitweb: http://repo.or.cz/w/git/mingw.git
Thanks to the recent additions of fake symlink support, this version is now self-hosting on Windows again.
Unfortunately, my time to work on this port is currently very limited. For this reason, this version is already a week behind Junio's master. This time I also did not make sure that the test-suite passes.
I also see that Shawn has updated the run_command family of functions to make them more useful for MinGW. But I fear I won't find time to integrate this work during this or next week.
