 * 
 * 18-Jul-94   fmu   - New CDDA icon (by Olivier Tonino)
 *                   - User-definable icon
 * 05-Jan-94   fmu   Retry displaying CD-DA icon if WB is not open.
 * 02-Jan-94   fmu   Location for CD-DA icon may be defined by user.
 * 11-Dec-93   fmu   Fixed AddAppIconA() call for DICE.
 * 28-Nov-93   fmu   Added custom CD-DA icon; removed GetDefDiskObject() call.
 * 09-Oct-93   fmu   SAS/C support added
