*Purpose:
*       This file defines the classes, values, macros, and functions
*       used by the stdiostream and stdiobuf classes.
*       [AT&T C++]

*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, 
*                       detab-ed.
