Thanks for the pointer. I am adding this (hopefully equivalent) test
case to the patch:
+
+template<class T, class U>
+struct S10
+{
+};
+
+template<class T>
+void
+test10(void)
+{
+ typedef typename ST<T>::T bar; // { dg-warning "locally defined but not
used" }
+ typedef typename ST<T>::T foo; // We shouldn't warn for this one, as
+ // it's used below.
+ S10<int, foo> v;
+}
