// File:      Standard_Stream.hxx
// Copyright: Open Cascade 2007
// Purpose:   Includes standard header files containing definition of streams;
//            defines macro USE_STL_STREAM if C++ standard STL streams are used
//            as opposed to obsolete non-standard streams.
//
//            Macro USE_OLD_STREAMS may be defined externally to command using 
//            old streams on WNT; otherwise new streams are used whenever available.
//
//            Macro NO_USING_STD may be defined externally to avoid "using"
//            declaratiions for types from std namespace.
