 *  This file contains the portability ugliness for the Standard C++
 *  Library.  As implementations of the "standard" emerge, this file
 *  will need to be updated.
 *
 *  This files deals with forward declaration for the stream
 *  classes.  Remember that since the new Standard C++ Library code
 *  for streams uses templates, simple forward declaration will not
 *  work.
