-// 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_CLASS(T) should evaluate to true if T is a class or struct type
-// BOOST_IS_ENUM(T) should evaluate to true if T is an enumerator type
-// 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
