Michel, is there any chance that you could test this behavior?

Now, also, I see that rename() works to rename directories on
Windows, but MoveFileEx with MOVEFILE_REPLACE_EXISTING will not
rename directories.  I guess that perhaps the solution to this is
to try MoveFileEx with flags of 0 first, and then try again with
MOVEFILE_REPLACE_EXISTING if that reports an error of
ERROR_ALREADY_EXISTS or ERROR_FILE_EXISTS (there is no
documentation on which one is returned).

I'm going away tomorrow morning until March 25, so possibly I'll
have to continue this discussion after that.
