//  BOOST_HAS_ABI_HEADERS
//  This macro gets set if we have headers that fix the ABI,
//  and prevent ODR violations when linking to external libraries:
#if defined(BOOST_ABI_PREFIX) && defined(BOOST_ABI_SUFFIX) && !defined(BOOST_HAS_ABI_HEADERS)
#  define BOOST_HAS_ABI_HEADERS
#endif

//  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.

# ifdef BOOST_NO_STDC_NAMESPACE

// 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.

// BOOST_USE_FACET / HAS_FACET workaround ----------------------------------//
// 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.
// Usage:
//    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.

#if defined(BOOST_NO_STD_USE_FACET)
#  ifdef BOOST_HAS_TWO_ARG_USE_FACET

// 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:
//
// typedef typename A::BOOST_NESTED_TEMPLATE rebind<U> binder;

#ifndef BOOST_NO_MEMBER_TEMPLATE_KEYWORD

// BOOST_UNREACHABLE_RETURN(x) workaround -------------------------------------//
// Normally evaluates to nothing, unless BOOST_NO_UNREACHABLE_RETURN_DETECTION
// is defined, in which case it evaluates to return x; Use when you have a return
// statement that can never be reached.

#ifdef BOOST_NO_UNREACHABLE_RETURN_DETECTION
#  define BOOST_UNREACHABLE_RETURN(x) return x;
#else
#  define BOOST_UNREACHABLE_RETURN(x)
#endif

// BOOST_DEDUCED_TYPENAME workaround ------------------------------------------//
//
// Some compilers don't support the use of `typename' for dependent
// types in deduced contexts, e.g.
//
//     template <class T> void f(T, typename T::type);
//                                  ^^^^^^^^
// Replace these declarations with:
//
//     template <class T> void f(T, BOOST_DEDUCED_TYPENAME T::type);

#ifndef BOOST_NO_DEDUCED_TYPENAME
#  define BOOST_DEDUCED_TYPENAME typename
#else
#  define BOOST_DEDUCED_TYPENAME
#endif

// long long workaround ------------------------------------------//
// On gcc (and maybe other compilers?) long long is alway supported
// but it's use may generate either warnings (with -ansi), or errors
// (with -pedantic -ansi) unless it's use is prefixed by __extension__
//
#if defined(BOOST_HAS_LONG_LONG)
namespace boost{
#  ifdef __GNUC__
   __extension__ typedef long long long_long_type;
   __extension__ typedef unsigned long long ulong_long_type;
#  else

   typedef unsigned long long ulong_long_type;
#  endif

#endif

// BOOST_[APPEND_]EXPLICIT_TEMPLATE_[NON_]TYPE macros --------------------------//
//
// Some compilers have problems with function templates whose
// template parameters don't appear in the function parameter
// list (basically they just link one instantiation of the
// template in the final executable). These macros provide a
// uniform way to cope with the problem with no effects on the
// calling syntax.

// Example:
//
//  #include <iostream>
//  #include <ostream>
//  #include <typeinfo>
//
//  template <int n>
//  void f() { std::cout << n << ' '; }
//
//  template <typename T>
//  void g() { std::cout << typeid(T).name() << ' '; }
//
//  int main() {
//    f<1>();
//    f<2>();
//
//    g<int>();
//    g<double>();
//  }
//
// With VC++ 6.0 the output is:
//
//   2 2 double double
//
// To fix it, write
//
//   template <int n>
//   void f(BOOST_EXPLICIT_TEMPLATE_NON_TYPE(int, n)) { ... }
//
//   template <typename T>
//   void g(BOOST_EXPLICIT_TEMPLATE_TYPE(T)) { ... }
//
