	* dbxout.c (dbxout_parms): Correctly describe parameters passed by
 	invisible reference in registers, but then spilled to the stack.
  	Remove code to emit a second stab for such parameters; it attempts

	(c_common_nodes_and_builtins): Create string_type_node,
	const_string_type_node, wint_type_node, intmax_type_node,
	uintmax_type_node, default_function_type, ptrdiff_type_node and
