+// 16 Feb 2001  Added a missing const. Made the tests run (somewhat) with

+//              MSVC without STLport, so that the other tests may proceed
+//              (David Abrahams)
+// 04 Feb 2001  Added use of iterator_tests.hpp (David Abrahams)
+// 28 Jan 2001  Removed not_an_iterator detritus (David Abrahams)
