+// Helper macros for builtin compiler support.
+// If your compiler has builtin support for any of the following
+// traits concepts, then redefine the appropriate macros to pick
+// up on the compiler support:
+//
+// (these should largely ignore cv-qualifiers)
+// BOOST_IS_UNION(T) should evaluate to true if T is a union type
+// BOOST_IS_POD(T) should evaluate to true if T is a POD type
+// BOOST_IS_EMPTY(T) should evaluate to true if T is an empty struct or union
+// BOOST_HAS_TRIVIAL_CONSTRUCTOR(T) should evaluate to true if "T x;" has no effect
+// BOOST_HAS_TRIVIAL_COPY(T) should evaluate to true if T(t) <==> memcpy
+// BOOST_HAS_TRIVIAL_ASSIGN(T) should evaluate to true if t = u <==> memcpy
+// BOOST_HAS_TRIVIAL_DESTRUCTOR(T) should evaluate to true if ~T() has no effect
+// BOOST_HAS_NOTHROW_CONSTRUCTOR(T) should evaluate to true if "T x;" can not throw
+// BOOST_HAS_NOTHROW_COPY(T) should evaluate to true if T(t) can not throw
+// BOOST_HAS_NOTHROW_ASSIGN(T) should evaluate to true if t = u can not throw
+// BOOST_HAS_VIRTUAL_DESTRUCTOR(T) should evaluate to true T has a virtual destructor
+//
+// The following can also be defined: when detected our implementation is greatly simplified.
+// Note that unlike the macros above these do not have default definitions, so we can use
+// #ifdef MACRONAME to detect when these are available.
+//
+// BOOST_IS_ABSTRACT(T) true if T is an abstract type
+// BOOST_IS_BASE_OF(T,U) true if T is a base class of U
+// BOOST_IS_CLASS(T) true if T is a class type
+// BOOST_IS_CONVERTIBLE(T,U) true if T is convertible to U
+// BOOST_IS_ENUM(T) true is T is an enum
+// BOOST_IS_POLYMORPHIC(T) true if T is a polymorphic type
+// BOOST_ALIGNMENT_OF(T) should evaluate to the alignment requirements of type T.
