>Description:
	The program below does not compile, although it is legal. Since class 'Derived'
	is derived from 'Base' and consequently should be granted access to its protected
	members, the compiler complains about member 'X' being protected.

class Base
{
  protected:
    int X;
};

class Derived : public Base
{
  public:
  int Get(void) const;
  int Get(const Base & cl) const;
};

int
Derived::Get(void) const
{
  return X;
}

int
Derived::Get(const Base & cl) const
{
  return cl.X;
}

>How-To-Repeat:
	Compile the program above.
>Fix:
	Workaround: make base class member public
