//  BOOST_NO_STDC_NAMESPACE workaround  --------------------------------------//
//  Because std::size_t usage is so common, even in boost headers which do not
//  otherwise use the C library, the <cstddef> workaround is included here so
//  that ugly workaround code need not appear in many other boost headers.
//  NOTE WELL: This is a workaround for non-conforming compilers; <cstddef>
//  must still be #included in the usual places so that <cstddef> inclusion
//  works as expected with standard conforming compilers.  The resulting
//  double inclusion of <cstddef> is harmless.

// BOOST_STATIC_CONSTANT workaround --------------------------------------- //
// On compilers which don't allow in-class initialization of static integral
// constant members, we must use enums as a workaround if we want the constants
// to be available at compile-time. This macro gives us a convenient way to
// declare such constants.

// When the standard library does not have a conforming std::use_facet there
// are various workarounds available, but they differ from library to library.
// The same problem occurs with has_facet.
// These macros provide a consistent way to access a locale's facets.

//    replace
//       std::use_facet<Type>(loc);
//    with
//       BOOST_USE_FACET(Type, loc);
//    Note do not add a std:: prefix to the front of BOOST_USE_FACET!
//  Use for BOOST_HAS_FACET is analagous.

// BOOST_NESTED_TEMPLATE workaround ------------------------------------------//
// Member templates are supported by some compilers even though they can't use
// the A::template member<U> syntax, as a workaround replace:

// typedef typename A::template rebind<U> binder;
//
// with:

// is defined, in which case it evaluates to return x; Use when you have a return
// statement that can never be reached.

// BOOST_DEDUCED_TYPENAME workaround ------------------------------------------//

// types in deduced contexts, e.g.
//
//     template <class T> void f(T, typename T::type);
//                                  ^^^^^^^^

// but it's use may generate either warnings (with -ansi), or errors
// (with -pedantic -ansi) unless it's use is prefixed by __extension__
//
