   4  * @(#)msd_dir.h 1.4 87/11/06   Public Domain.
   5  *
   6  *  A public domain implementation of BSD directory routines for
   7  *  MS-DOS.  Written by Michael Rendell ({uunet,utai}michael@garfield),
   8  *  August 1897
   9  *
  10  *  Extended by Peter Lim (lim@mullian.oz) to overcome some MS DOS quirks
  11  *  and returns 2 more pieces of information - file size & attribute.
  12  *  Plus a little reshuffling of some #define's positions    December 1987
  13  *
  14  *  Some modifications by Martin Junius                      02-14-89
