The following code was compiled with g++ 1.35 and also with the test
version of 1.36.  Both produced the error message shown.  I need to
know if this is correct behavior or not.  Also, I need to know if
virtual operators should work in the same manner as virtual functions.

class A { public:
  operator=(int i) {value=i;}
private:
  int value;
};

class B : public A {
public:
};

main() {
  A a;
  a = 3;
  B b;
  b.operator=(3);
  b = 3; //vop.cc:17: assignment not defined for type `B'
}

Being able to use the functional syntax but not the operator syntax seems inconsistent.
