-The 971114 "gcc/cp/parse.y" doesn't properly identify non-aggregate
-types used as base classes.
-
-First, the rule:
-
-        base_class: base_class_access_list see_typename base_class.1
-
-uses "IS_AGGR_TYPE" instead of "is_aggr_type" to check "base_class.1",
-so no error is reported for code like:
-
+Check whether a typedef for a basic type as a baseclass is diagnosed.
