[Bug c++/13478] [3.3/3.4 Regression] gcc uses wrong constructor to initialize a const reference

Ok. Given:

------------------------------------
struct A {};
struct B : protected A {
    B() {};
    B(const A& ) {};
private:
    B(const B& ) {};
};

void foo(const A* ap)
{
  const B& br = *ap;
}
------------------------------------

The code should compile, because it should call B(const A&) to construct the 
temporary which is then bound to the const reference. Instead, GCC seems to 
call B(const B&), which is private. I can't test on 3.0/3.1, but it's surely a 
regression since 3.0.4, and can be made a wrong-code one if we make the 
constructor public. I keep it as rejects-valid as it's easier to debug.
