The following program:

void f( int x )
{
        class InnerClass
        {
                public:
                        static void g( int x )
                        {
                        // empty
                        }
        };
}

produces a warning:

t.cc: In static member function 'static void f(int)::InnerClass::g(int)':
t.cc:7: warning: declaration of 'int x' shadows a parameter
t.cc:1: warning: shadowed declaration is here

But it would be invalid for any function in InnerClass to try and use the outer
"int x" (and in fact if you try it, you correctly get an error).
