Well, with gcc 3.0 (solaris 2.5.1) compiling with c++ (as opposed to g++
or gcc)

#include <iostream.h>

int main()
{
        long long i=10;

        cout << i << endl;

        return(0);
}


I get the following error...

t2.cpp: In function `int main()':
t2.cpp:8: ambiguous overload for `std::ostream& << long long int&'
