// 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.
