// 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
