ANSI C++ changes revisited

[Bill Hoffman]

It has to be in a .h file.

The PrintSelf methods look like this:

   void PrintSelf(ostream& os, vtkIndent indent);

Also, many VTK functions that manipulate ostream are defined
in .h files (inlines).   So we can not just forward reference
the ostreams.   

You have code that has endl as a function???
That sounds like it would only work with a newer compiler as it would
conflict with the old iostream.h.  I assume that your endl
is in another namespace.
