If only MS Windows supported other filesystems which have symlinks...

First, I think that both "git on Windows" solutions, namely Cygwin and
msysGit port, don't use symlinks either in installed programs, nor in
repository layout.

Second, the problem there can be _only_ if your repository contains
(or contained) symlinks, and then it is your own damn fault.  I don't
know how Cygwin, or msysGit deals with symlinks in a wirking
directory, but you can work around symlinks (although in a bit
unwieldy way) by using `core.symlinks' configuration variable;
see git-config(1):

 core.symlinks::
        If false, symbolic links are checked out as small plain files
        that contain the link text. git-update-index(1) and git-add(1)
        will not change the recorded type to regular file. Useful on
        filesystems like FAT that do not support symbolic links. True
        by default.
