	it with repeated code, while replacing this code with a jump.

	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.

	and fix it if it is a component reference.
	(build_array_ref): Simplify handling of class array refs by
	passing the vptr to gfc_build_array_ref rather than generating
	the pointer arithmetic in this function.
	(gfc_conv_array_ref): As in gfc_conv_scalarized_array_ref, set
	'decl'.

	for remap and, since the 'start' indices are missing, set the
	lbounds to one, as required by the standard.
	* trans-intrinsic.c (conv_expr_ref_to_caf_ref): Pick up the
	'token' offset from the field decl in the descriptor.
	(conv_isocbinding_subroutine): Set the 'span' field.

	(gfc_build_array_ref): Simplify by calling get_array_span and
	obtain 'span' if 'decl' or 'vptr' present.

	'kind_expr'. Check that KIND or LEN components appear in the

	copy the decl_type_param_list to the component param_list.
	(gfc_match_kind_spec): If the KIND expression is parameterized

	formal symbol to the f2k_derived namespace.
	(gfc_match_derived_decl): Register the decl_type_param_list

	the type parameters and put them in the right order.
