        * decl.c (grokdeclarator): Don't decay array parameter type to
        a pointer type if it's dependent.
        (grokparms): Invoke strip_top_quals instead of directly invoking
        cp_build_qualified_type.
        * pt.c (decay_dependent_array_parm_type): New static function.
        (type_unification_real): Call decay_dependent_array_parm_type
        to decay a dependent array parameter type to its corresponding
        pointer type before unification.
        (more_specialized_fn): Likewise.
        (get_bindings): Likewise.
        * tree.c (cp_build_qualified_type): Trivial typofix in
        documentation.
