        * decl.c (variable_decl): Check pdt template components for
        appearance of KIND/LEN components in the type parameter name
        list, that components corresponding to type parameters have
        either KIND or LEN attributes and that KIND or LEN components
        are scalar. Copy the initializer to the parameter value.
        (gfc_get_pdt_instance): Add a label 'error_return' and follow
        it with repeated code, while replacing this code with a jump.
        Check if a parameter appears as a component in the template.
        Make sure that the parameter expressions are integer. Validate
        KIND expressions.
        (gfc_match_decl_type_spec): Search for pdt_types in the parent
        namespace since they are instantiated in the template ns.
        * expr.c (gfc_extract_int): Use a KIND parameter if it
        appears as a component expression.
        (gfc_check_init_expr): Allow expressions with the pdt_kind
        attribute.
        *primary.c (gfc_match_actual_arglist): Make sure that the first
        keyword argument is recognised when 'pdt' is set.
