	* cp-tree.h (push_template_decl): Return the decl passed in, or an
	equivalent duplicate.
	* decl.c (pushtag): Use the return value from push_template_decl.
	(duplicate_decls): When duplicating a template declaration, merge
	the DECL_TEMPLATE_RESULTs as well.
	(make_implicit_typename): Don't try to dive into typename types to
	find a context for making a new implicit typename.
	(start_decl): Use the return value from push_template_decl.
	(grokdeclarator): Complain about declarations list `const operator
	int'.  Since we don't correctly handle in-class initializations of
	non-static data members, complain about this (now illegal)
	practice.  Issue an error for initializations of non-const statics
	since that is illegal as well, and since we don't handle that case
	correctly either.
	(start_function): Use the return value from push_template_decl.
	(start_method): Likewise.
	* decl2.c (grokfield): Likewise.  Since the change to
	grokdeclarator ensures that all initialized fields are in fact
	static, remove a redundant test for TREE_PUBLIC.
	* parse.y (initlist): Disable labeled initializers since they do
	not work as per the documentation, and since they do not use the
	same syntax as the C front end.
	* pt.c (push_template_decl): Return the decl passed in, or an
	equivalent duplicate.
	(lookup_template_class): When searching in a nested context,
	use the right arguments.
	(uses_template_parms): Handle the DECL_INITIAL for a CONST_DECL.
	* typeck.c (build_component_ref): Assign the correct type to the
	result of build_vfn_ref.
