At least some of these informations should go into the commit message, 
too.

I saw some funny stuff on Windows, like test cases succeeding when run 
interactively, but failing when run from "make test".

BTW it would have been way easier to apply your patch, had you followed 
SubmittingPatches...

To make it easier on others, I just uploaded it into the "teststat" branch 
on 4msysgit.git (subject to removal in a few days).

First comment: it seems git_fstat() is not declared properly, so there are 
quite a few compiler warnings.

Running the tests now.
