+//
+// This file provides a wrapper around the mysterious <iterator> header file.
+// In GCC 2.95.3, the file defines a bidirectional_iterator class (and other
+// friends), instead of the standard iterator class.  In GCC 3.1, the
+// bidirectional_iterator class got moved out and the new, standards compliant,
+// iterator<> class was added.  Because there is nothing that we can do to get
+// correct behavior on both compilers, we have this header with #ifdef's.  Gross
+// huh?
+//
+// By #includ'ing this file, you get the contents of <iterator> plus the
+// following classes in the global namespace:
+//
+//   1. bidirectional_iterator
+//   2. forward_iterator
+//
+// The #if directives' expressions are filled in by Autoconf.
