Windows's rename() is based on the MoveFile() API, which fails if the destination exists. Here we work around the problem by using MoveFileEx(). Furthermore, the posixly correct error is returned if the destination is a directory. The implementation is still slightly incomplete, however, because of the missing error code translation: We assume that the failure is due to permissions.
