*
*Purpose:
* This file defines the DOS packed date and time types.
*
*Revision History:
* 11-18-87 SKS Removed declaration of _dtoxtime
* 09-27-88 JCR 386 versions of macros
* 10-03-88 GJF Use M_I386, not I386
* 05-01-89 JCR Fixed 386 versions for new rev of OS/2 386
* 08-03-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
* 10-30-89 GJF Fixed copyright
* 02-28-90 GJF Added #ifndef _INC_DOSTYPES stuff
* 08-11-90 SBM Enhanced SET_DOS_* macros to compile cleanly with -W3
* 04-09-91 PNT Added _MAC_ definitions
