/* $Id$
 * TRUENAME.C -- Truename Command (undocumented DOS?)
 *
 * 07/14/98 (Rob Lake)
 *  - started and tested fine
 *  - added stand alone debugging
 *
 * 27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
 * - added config.h include
 *
 * 28-Jul-1998 (John P Price <linux-guru@gcfl.net>)
 * - changed _truename function so it does not return a pointer to a local
 *   variable.
 *
 * 09-Aug-1998 (Rob Lake <rlake@cs.mun.ca>)
 * - _truename now sets errno
