2 int*& foo (int const *& x)
4 return const_cast<int*&> (x);
8 If the references in this example are changed to pointers (change
9 all `&''s to `*'), no warnings result.
11 I think this is incorrect according to CD2 5.2.11, para 4:
13 4 An lvalue of type T1 can be explicitly converted to an lvalue of type
14 T2 using the cast const_cast<T2&> (where T1 and T2 are object types)
15 if a pointer to T1 can be explicitly converted to the type pointer to
16 T2 using a const_cast. The result of a reference const_cast refers to
