* 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.
