+// Test instantiates std::vector on a user-defined type, user-defined
+// allocator and a user-defined pointer type, making sure that everything
+// still compiles and runs with expected results
+
+// Note: 20.1.5, p2, Allocator requirements specifies that the type
+// std::allocator<T>::pointer be a "pointer to T", which might
+// make this test case not well-defined; it is expected that
+// this will be changed in a future revision of the Standard
+
+// user-defined pointer type
