g++ 3.0.1 on Solaris 8
>Description:
When access adjustment is used in the body of a class for member functions that are overload on const, all calls resolve (incorrectly) to the const overload.
>How-To-Repeat:
Here is a short test case:

#include <iostream>

using namespace std;

struct A {

  void foo() { cout << "non const" << endl;  }
  void foo() const { cout << "const" << endl;  }


};

struct B : private A {

    using A::foo;

};

int main() {

  B b;
  b.foo();

  return 0;
}  

output:
const
