*	Copyright (c) 1991-1992, Microsoft Corporation.  All rights reserved.
*
*Purpose:
*	Contains the member function definitions for iostream classes.  Also,
*	precompile all header files used by iostream lib into iostream.pch.
*
*Revision History:
*	09-23-91   KRS	Created.
*	11-13-91   KRS	Rearranged.
*	11-20-91   KRS	Added copy constructor and assignment operators.
*	01-23-92   KRS	Merge pch.cxx into this file.
