      fails if the parent directory is the root and is full
      DOS 2.x-3.3 allow the creation of a directory sufficiently deep that
        it is not possible to make that directory the current directory
        because the path would exceed 64 characters
      under the FlashTek X-32 DOS extender, the pointer is in DS:EDX
