It's not a shame, it's a feature :)

The older cygwin snapshots has generated i-node numbers by hashing over
the filename, which has the advantage, that `mv' works for the mentioned
situation by accident. But the disadvantage of this older implementation
is simply, that it wasn't able to realize, that two directory entries
are the same file. This isn't important on FAT, but NTFS allows real
hard links.
