   ???

Return: ???
Desc:  create a new directory, with extended attribute information

Note:  also supported by OS/2 v2.0+ Virtual DOS Machines
BUG:   does not work under OS/2 v2.0 because MVDM does not translate the
     real-mode segment pointer in the Extended Attribute structure
     (see #1359) into a protected-mode selector; use AH=39h followed by
     AX=5703h instead
