-// Conformance Flag Macros -------------------------------------------------//
-//
-// Conformance flag macros should identify the absence of C++ Standard
-// conformance rather than its presence. This ensures that standard conforming
-// compilers do not require a lot of configuration flag macros. It places the
-// burden where it should be, on non-conforming compilers. In the future,
-// hopefully, less rather than more conformance flags will have to be defined.
-
-// BOOST_NO_DEPENDENT_TYPES_IN_TEMPLATE_VALUE_PARAMETERS: Template value
-// parameters cannot have a dependent type, for example
-// "template<class T, typename T::type value> class X { ... };"
-
-// BOOST_NO_INCLASS_MEMBER_INITIALIZATION: Compiler violates std::9.4.2/4.
-
-// BOOST_NO_MEMBER_TEMPLATES: Member template functions not fully supported.
-// Also see BOOST_MSVC6_MEMBER_TEMPLATES in the Compiler Control section below.
-
-// BOOST_NO_MEMBER_TEMPLATE_FRIENDS: Member template friend syntax
-// ("template<class P> friend class frd;") described in the C++ Standard,
-// 14.5.3, not supported.
-
-// BOOST_NO_OPERATORS_IN_NAMESPACE: Compiler requires inherited operator
-// friend functions to be defined at namespace scope, then using'ed to boost.
-// Probably GCC specific. See boost/operators.hpp for example.
-
-// BOOST_NO_POINTER_TO_MEMBER_CONST: The compiler does not correctly handle
-// pointers to const member functions, preventing use of these in overloaded
-// function templates. See boost/functional.hpp for example.
-
-// BOOST_NO_PRIVATE_IN_AGGREGATE: The compiler misreads 8.5.1, treating classes
-// as non-aggregate if they contain private or protected member functions.
-
-// BOOST_NO_STD_ITERATOR: The C++ implementation fails to provide the
-// std::iterator class.
-
-// BOOST_NO_STD_ITERATOR_TRAITS: The compiler does not provide a standard
-// compliant implementation of std::iterator_traits. Note that
-// the compiler may still have a non-standard implementation.
-
-// BOOST_NO_STDC_NAMESPACE: The contents of C++ standard headers for C library
-// functions (the <c...> headers) have not been placed in namespace std.
-// Because the use of std::size_t is so common, a specific workaround for
-// <cstddef> (and thus std::size_t) is provided in this header (see below).
-// For other <c...> headers, a workaround must be provided in the boost header:
//
-// #include <cstdlib> // for abs
-// #ifdef BOOST_NO_STDC_NAMESPACE
-// namespace std { using ::abs; }
-// #endif
-
-// BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION. Class template partial
-// specialization (14.5.4 [temp.class.spec]) not supported.
-
-// BOOST_NO_USING_TEMPLATE: The compiler will not accept a using declaration
-// that imports a template from the global namespace into a named namespace.
-// Probably Borland specific.
-
-// Compiler Control or Information Macros ----------------------------------//
-//
-// Compilers often supply features outside of the C++ Standard which need to be
-// controlled or detected. As usual, reasonable default behavior should occur
-// if any of these macros are not defined.
-
-// BOOST_DECL: Certain compilers for Microsoft operating systems require
-// non-standard class and function decoration if dynamic load library linking
-// is desired. BOOST_DECL supplies that decoration, defaulting to a nul string
-// so that it is harmless when not required. Boost does not encourage the use
-// of BOOST_DECL - it is non-standard and to be avoided if practical to do so.
-
-// BOOST_DECL_EXPORTS: User defined, BOOST_DECL_EXPORTS causes BOOST_DECL to
-// be defined as __declspec(dllexport) rather than __declspec(dllimport).
-
-// BOOST_MSVC6_MEMBER_TEMPLATES: Microsoft Visual C++ 6.0 has enough member
-// template idiosyncrasies (being polite) that BOOST_NO_MEMBER_TEMPLATES is
-// defined for this compiler. BOOST_MSVC6_MEMBER_TEMPLATES is defined to allow
-// compiler specific workarounds.
-
-// BOOST_MSVC: defined as _MSC_VER for the Microsoft compiler only. In general,
-// boost headers should test for a specific conformance flag macro (for
-// example, BOOST_NO_MEMBER_TEMPLATE_FRIENDS) rather than a specific compiler.
-// VC++ is a special case, however, since many libraries try to support it yet
-// it has so many conformance issues that sometimes it is just easier to test
-// for it directly. On the other hand, the obvious way to do this doesn't work,
-// as many non-Microsoft compilers define _MSC_VER. Thus BOOST_MSVC.
-
-// BOOST_MSVC_STD_ITERATOR: Microsoft's broken version of std::iterator
-// is being used.
-
-// BOOST_SYSTEM_HAS_STDINT_H: There are no 1998 C++ Standard headers <stdint.h>
-// or <cstdint>, although the 1999 C Standard does include <stdint.h>.
-// If <stdint.h> is present, <boost/stdint.h> can make good use of it,
-// so a flag is supplied (signalling presence; thus the default is not
-// present, conforming to the current C++ standard).
-
-// BOOST_NO_SLIST: The C++ implementation does not provide the slist class.
-
-// BOOST_NO_HASH: The C++ implementation does not provide the hash_set
-// or hash_map classes.
-
-// BOOST_NO_TEMPLATED_ITERATOR_CONSTRUCTORS: The standard library does not provide
-// templated iterator constructors for its containers.
-
-// BOOST_NO_LIMITS: The C++ implementation does not provide the <limits> header.
-
-// BOOST_NO_INTRINSIC_WCHAR_T: The C++ implementation does not provide wchar_t,
-// or it is really a synonym for another integral type. Use this symbol to
-// decide whether it is appropriate to explicitly specialize a template on
-// wchar_t if there is already a specialization for other integer types.
-
-// BOOST_NO_STD_ALLOCATOR: The C++ standard library does not provide
-// a standards conforming std::allocator.
-
-// Compilers are listed in alphabetic order (except VC++ last - see below)---//
