Sorry, to be a pain in the ass ;), but the reference stuff is still not
completely right.  The above patch, which indeed fixed some cases breaks
another one, namely this:

------- snip --------
struct A { };
struct B : public A { };
struct X {
        operator B();
};
X x;

int main()
{
  const A& r = x;
  return 0;
}
------- snap --------

In HEAD and 3.3 branch this currently gives:

bla.cc:10: internal compiler error: in initialize_reference, at
   cp/call.c:6093

If going back to just before your patch went in, it compiles.


Ciao,
Michael.
