// 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
# include <cstddef>

// 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 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.
// This macro provides 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!

// 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:
//

// Converts the parameter X to a string after macro replacement
// on X has been performed.
//
#define BOOST_STRINGIZE(X) BOOST_DO_STRINGIZE(X)

//
// Helper macro BOOST_JOIN:
// The following piece of macro magic joins the two
// arguments together, even when one of the arguments is
// itself a macro (see 16.3.1 in C++ standard). The key
// is that macro expansion of macro arguments does not
// occur in BOOST_DO_JOIN2 but does in BOOST_DO_JOIN.
