* 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.
