//  Revision History
//  22 Feb 16 Preserve old work-arounds. (Daniel Frey)
//  16 Dec 10 Limit warning suppression for 4284 to older versions of VC++
//            (Matthew Bradbury, fixes #4432)
//  07 Aug 08 Added "euclidean" spelling. (Daniel Frey)
//  03 Apr 08 Make sure "convertible to bool" is sufficient
//            for T::operator<, etc. (Daniel Frey)
//  24 May 07 Changed empty_base to depend on T, see
//            http://svn.boost.org/trac/boost/ticket/979
//  21 Oct 02 Modified implementation of operators to allow compilers with a
//            correct named return value optimization (NRVO) to produce optimal
//            code.  (Daniel Frey)
//  02 Dec 01 Bug fixed in random_access_iteratable.  (Helmut Zeisel)
//  28 Sep 01 Factored out iterator operator groups.  (Daryle Walker)
//  27 Aug 01 'left' form for non commutative operators added;
//            additional classes for groups of related operators added;
//            workaround for empty base class optimization
//            bug of GCC 3.0 (Helmut Zeisel)
//  25 Jun 01 output_iterator_helper changes: removed default template 
//            parameters, added support for self-proxying, additional 
//            documentation and tests (Aleksey Gurtovoy)
//  29 May 01 Added operator classes for << and >>.  Added input and output
//            iterator helper classes.  Added classes to connect equality and
//            relational operators.  Added classes for groups of related
//            operators.  Reimplemented example operator and iterator helper
//            classes in terms of the new groups.  (Daryle Walker, with help
//            from Alexy Gurtovoy)
//  11 Feb 01 Fixed bugs in the iterator helpers which prevented explicitly
//            supplied arguments from actually being used (Dave Abrahams)
//  04 Jul 00 Fixed NO_OPERATORS_IN_NAMESPACE bugs, major cleanup and
//            refactoring of compiler workarounds, additional documentation
//            (Alexy Gurtovoy and Mark Rodgers with some help and prompting from
//            Dave Abrahams) 
//  28 Jun 00 General cleanup and integration of bugfixes from Mark Rodgers and
//            Jeremy Siek (Dave Abrahams)
//  20 Jun 00 Changes to accommodate Borland C++Builder 4 and Borland C++ 5.5
//            (Mark Rodgers)
//  20 Jun 00 Minor fixes to the prior revision (Aleksey Gurtovoy)
//  10 Jun 00 Support for the base class chaining technique was added
//            (Aleksey Gurtovoy). See documentation and the comments below 
//            for the details. 
//  12 Dec 99 Initial version with iterator operators (Jeremy Siek)
//  18 Nov 99 Change name "divideable" to "dividable", remove unnecessary
//            specializations of dividable, subtractable, modable (Ed Brey) 
//  17 Nov 99 Add comments (Beman Dawes)
//            Remove unnecessary specialization of operators<> (Ed Brey)
//  15 Nov 99 Fix less_than_comparable<T,U> second operand type for first two
//            operators.(Beman Dawes)
//  12 Nov 99 Add operators templates (Ed Brey)
//  11 Nov 99 Add single template parameter version for compilers without
//            partial specialization (Beman Dawes)
//  10 Nov 99 Initial version

// 10 Jun 00:
// An additional optional template parameter was added to most of 
// operator templates to support the base class chaining technique (see 
// documentation for the details). Unfortunately, a straightforward
// implementation of this change would have broken compatibility with the
// previous version of the library by making it impossible to use the same
// template name (e.g. 'addable') for both the 1- and 2-argument versions of
// an operator template. This implementation solves the backward-compatibility
// issue at the cost of some simplicity.
//
// One of the complications is an existence of special auxiliary class template
// 'is_chained_base<>' (see 'detail' namespace below), which is used
// to determine whether its template parameter is a library's operator template
// or not. You have to specialize 'is_chained_base<>' for each new 
// operator template you add to the library.
//
// However, most of the non-trivial implementation details are hidden behind 
// several local macros defined below, and as soon as you understand them,
// you understand the whole library implementation.
