// Revision History
// 02 Jun 14 Remove VC6 workarounds.
// 16 Jul 11 Bugfixes for VC6.
// 23 JUN 05 Code extracted from /boost/cast.hpp into this new header.
// Keeps this legacy version of numeric_cast<> for old compilers
// wich can't compile the new version in /boost/numeric/conversion/cast.hpp
// (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
