	* decl.c (lookup_name_real): Add implicit 'typename' to types from
	base classes.

	* pt.c (most_specialized_class): Fix typo.
	(tsubst): Move constant folding to TREE_VEC case.

	* pt.c (do_poplevel): Don't warn about unused local variables
	while processing_template_decl since we don't always know whether
	or not they will need constructing/destructing.

	* pt.c (uses_template_parms): Check the values of an enumeration
	type to make sure they don't depend on template parms.

	* decl.c (make_typename_type): Don't lookup the field if the
	context uses template parms, even if we're not
	processing_template_decl at the moment.

	* pt.c (coerce_template_parms): Avoid looking at the
	TYPE_LANG_DECL portion of a typename type, since there won't be
	one.
	(tsubst): Do constant folding as necessary to make sure that
	arguments passed to lookup_template_class really are constants.
