+//  Revision History
+//  23 JUn 05  numeric_cast removed and redirected to the new verion (Fernando Cacciola)
+//  02 Apr 01  Removed BOOST_NO_LIMITS workarounds and included
+//             <boost/limits.hpp> instead (the workaround did not
+//             actually compile when BOOST_NO_LIMITS was defined in
+//             any case, so we loose nothing). (John Maddock)
+//  21 Jan 01  Undid a bug I introduced yesterday. numeric_cast<> never
+//             worked with stock GCC; trying to get it to do that broke
+//             vc-stlport.
+//  20 Jan 01  Moved BOOST_NO_LIMITS_COMPILE_TIME_CONSTANTS to config.hpp.
+//             Removed unused BOOST_EXPLICIT_TARGET macro. Moved
+//             boost::detail::type to boost/type.hpp. Made it compile with
+//             stock gcc again (Dave Abrahams)
+//  29 Nov 00  Remove nested namespace cast, cleanup spacing before Formal
+//             Review (Beman Dawes)
+//  19 Oct 00  Fix numeric_cast for floating-point types (Dave Abrahams)
+//  15 Jul 00  Suppress numeric_cast warnings for GCC, Borland and MSVC
+//             (Dave Abrahams)
+//  30 Jun 00  More MSVC6 wordarounds.  See comments below.  (Dave Abrahams)
+//  28 Jun 00  Removed implicit_cast<>.  See comment below. (Beman Dawes)
+//  27 Jun 00  More MSVC6 workarounds
+//  15 Jun 00  Add workarounds for MSVC6
+//   2 Feb 00  Remove bad_numeric_cast ";" syntax error (Doncho Angelov)
+//  26 Jan 00  Add missing throw() to bad_numeric_cast::what(0 (Adam Levar)
+//  29 Dec 99  Change using declarations so usages in other namespaces work
+//             correctly (Dave Abrahams)
+//  23 Sep 99  Change polymorphic_downcast assert to also detect M.I. errors
+//             as suggested Darin Adler and improved by Valentin Bonnard.
+//   2 Sep 99  Remove controversial asserts, simplify, rename.
+//  30 Aug 99  Move to cast.hpp, replace value_cast with numeric_cast,
+//             place in nested namespace.
+//   3 Aug 99  Initial version
