iostream vs iostream.h

[apark@cdf.toronto.edu]

Hi,

I've just compiled and installed gcc 3.0.1.
When I compile any c++ code with

	#include <iostream>

instead of

	#include <iostream.h>

the compilation breaks saying that some functions are
undeclared (such as cout.) Have I broken something?
Thanks

p.s.  Please CC me since I'm not on the list.
