Well, yeah. That's how the language and library are /supposed/ to work.
There's no bug here.
If you include the C++ headers that don't have a ".h" at the end of their
names, then everything is in namespace std. And others have already
discussed some good rules on how to import the names.
The "old code" you're compiling can't be very old if it's using the new
headers like <iostream>. If old code uses old headers like <iostream.h>
then 'cout' and other names are already visible.
