When trying to compile the below program, I get a message saying that 'cout' is not a member of 'std', what the heck is that message for?!

Is this a bug in g++

SPECS -
MSW-XP
DEV-CPP - MINWING - GCC 3.3.x

#include <gtkmm/button.h>
#include <gtkmm/window.h>
#include <gtkmm/main.h>
#include <string>

class HelloWorld : virtual public Gtk::Window{
public:
HelloWorld();
virtual ~HelloWorld();

protected:
//Signal handlers:
virtual void on_button_clicked();

//Member widgets:
Gtk::Button m_button;
};
// creates a new button with the label "Hello World".
HelloWorld::HelloWorld() : m_button("Hello World"){

// Sets the border width of the window.
set_border_width(10);

// When the button receives the "clicked" signal, it will call the
// on_button_clicked() method. The on_button_clicked() method is defined below.
m_button.signal_clicked().connect(sigc::mem_fun(*this, &HelloWorld::on_button_clicked));

// This packs the button into the Window (a container).
add(m_button);

// The final step is to display this newly created widget...
m_button.show();
}

HelloWorld::~HelloWorld(){}
/* ?????????????????????? HERE IS THE PROBLE ????????????????? */
void HelloWorld::on_button_clicked(){
std::cout << "Hello World" << std::endl;
}

int main (int argc, char *argv[])
{
Gtk::Main kit(argc, argv);

HelloWorld helloworld;
Gtk::Main::run(helloworld); //Shows the window and returns when it is closed.

return 0;
}

You need to include <iostream>...
