    re PR c++/20332 (poor diagnostic when bind non lvalue to a reference for
default arguments)

            * call.c (reference_binding): Treat lvalue/rvalue mismatch and
            dropped cv-quals as a bad conversion.
            (convert_like_real) [ck_ref_bind]: Explain them.
            (compare_ics): Check badness before stripping reference
            bindings.  Handle comparing bad reference bindings.
            * typeck.c (comp_cv_qualification): Add overload that just takes
            integers.
            * cp-tree.h: Declare it.=
