*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.
* 12-14-95 JWM Add "#pragma once".
* 03-04-96 JWM Made entire file #ifdef _OLD_IOSTREAMS.
* 04-09-96 SKS Change _CRTIMP to _CRTIMP1 for special iostream build
* 04-15-96 JWM Remove _OLD_IOSTREAMS, add '#pragma comment(lib,"cirt")'.
* 04-16-96 JWM '#include useoldio.h' replaces '#pragma comment(...)'.
* 02-24-97 GJF Cleaned out obsolete support for _NTSDK. Also,
