I've just pushed an update of the MinGW port to:
clone: git://repo.or.cz/git/mingw.git gitweb: http://repo.or.cz/w/git/mingw.git
It is now at v1.5.3.rc2.
NOTE! This is only lightly tested, i.e. it passes (most of) the test suite(*), but it hasn't been used in production, yet.
If you need a known working version, pick the state at the tags
mingw-v1.5.2.4-devel mingw-v1.5.2.4
(You must fetch mingw-v1.5.2.4-devel explicitly; it is not on any branch.)
(*) It does pass the tests of the important tools, so...
