*
*Revision History:
*	01-23-92  KRS	Ported from 16-bit version.
*	02-23-93  SKS	Update copyright to 1993
*	10-12-93  GJF	Support NT and Cuda builds. Enclose #pragma-s in
*			#ifdef _MSC_VER
*	08-12-94  GJF	Disable warning 4514 instead of 4505.
*	11-03-94  GJF	Changed pack pragma to 8 byte alignment.
*       02-11-95  CFW   Add _CRTBLD to avoid users getting wrong headers.
*       02-14-95  CFW   Clean up Mac merge.
*       05-11-95  CFW   Only for use by C++ programs.
