>Description:
g++ accepts the following code without generating a warning or an error, though it should warn about trying to access the private member "foo" of class A:

/* snip */

class A {
  static int foo;
};
int A::foo = 42;

class B : public A {
public:
  int MyFoo(void) 
  { 
    return foo; 
  }
};

int main(int argc,char **argv)
{
  class B b;

  return b.MyFoo();
}
>How-To-Repeat:
Save the above program as "foo.cpp", then compile as follows:

$ g++ -Wall foo.cpp

g++ will compile the program without generating an error or a warning, even though A::foo is private within B::MyFoo. g++ will warn if the initializer for A::foo is moved out of sight.
