Subject: [PATCH] cp-tree.h (struct language_function): Remove static_labelno.

	* cp-tree.h (struct language_function): Remove static_labelno.
	(static_labelno): Remove macro.
	* method.c (build_overload_nested_name): Make static_labelno
	static here.

	* pt.c (instantiate_decl): Use DECL_SAVED_TREE, not DECL_INITIAL,
	to decide whether or not a function is defined.
