/*
 * @(#)msd_dir.h 1.4 87/11/06   Public Domain.
 *
 *  A public domain implementation of BSD directory routines for
 *  MS-DOS.  Written by Michael Rendell ({uunet,utai}michael@garfield),
 *  August 1897
 *
 *  Extended by Peter Lim (lim@mullian.oz) to overcome some MS DOS quirks
 *  and returns 2 more pieces of information - file size & attribute.
 *  Plus a little reshuffling of some #define's positions    December 1987
 *
 *  Some modifications by Martin Junius                      02-14-89
 *
 *  AK900712
 *  AK910410    abs_path - make absolute path
