* decl.c (check_initializer): Try to complete the type of an

        array element before checking whether it's complete.  Don't
        complain about arrays with complete element types but an
        unknown size.
        (cp_finish_decl): Build the hierarchical constructor before
        calling maybe_deduce_size_from_array_init.
