[Bug c++/20397] New: g++ rejects valid code with 'is inaccessible' error

[matthew dot whitney at gmail dot com]

Example code:

class A {
};

class B : A {
};

class C : B {
public:
        int c(A *a) { return 7; }
};

int main() { 
        
        A a;
        C c;

        return c.c( &a );
}

Gives the error message:

g++ main.cc
        main.cpp:1: `class A' is inaccessible
        main.cpp:9: within this context

Which is true, but not relevant. C never tries to access A through B.
