 // Revision History:
 
+// 04 Oct 2001   Jeremy Siek
+//      Changed projection_iterator to not rely on the default reference,
+//      working around a limitation of detail::iterator_traits.
 // 04 Oct 2001   David Abrahams
 //      Applied indirect_iterator patch from George A. Heintzelman <georgeh@aya.yale.edu>
 //      Changed name of "bind" to "select" to avoid problems with MSVC.
