g++ 1.32 (under SunOs 3.5, sun 3/60) allows the following
program which is illegal according to Stroustrup's book
(The C++ programming language), example on page 197.

class base {
	int     m1;
public:
	int     m2;
};

class derived : base {
};

derived d;
base    *pb= &d;        // error (private base)
