Details:

On Cygwin using non-managed mounts (and presumably other operating systems
when using a case-insensitive file system), it's not possible to use Coreutils
mv to change the case of a filename; mv reports that they are the same file.

The underlying Cygwin rename() function does support this functionality.

Also see the thread on the Cygwin mailing list starting at
<http://cygwin.com/ml/cygwin/2007-08/msg00335.html>.

Example:

$ touch foo
$ mv foo Foo
mv: `foo' and `Foo' are the same file
$ mv --version
mv (GNU coreutils) 6.9
