Maybe the gcc 3.4 diagnostic is better:

It is required by the ISO C++ standard.

Any code which uses classic iostreams should be updated to use standard
iostreams.
GCC >= 3.0 does not support classic iostreams. "iostream.h" is just:
#include "backward_warning.h"
#include <iostream>
and some appropriate using declarations. For simple cases this is
backward-compatible with classic iostreams, but in some cases it
is not.
So if you tried to use 'both' you would really be using the same
iostreams in both places.

No.
