[section:has_nothrow_copy has_nothrow_copy]

   template <class T>
   struct has_nothrow_copy : public __tof {};
  
   template <class T>
   struct has_nothrow_copy_constructor : public __tof {};
  
__inherit If T is a (possibly cv-qualified) type with a non-throwing copy-constructor
then inherits from __true_type, otherwise inherits from __false_type.  Type `T`
must be a complete type.

These two traits are synonyms for each other.

__compat Either requires C++11 `noexcept` and `decltype` or else some (unspecified) help from the compiler.
Currently (June 2015) compilers more recent than Visual C++ 8, GCC-4.3, Greenhills 6.0, 
Intel-11.0, and Codegear and all recent GCC versions have the necessary compiler __intrinsics to ensure that this 
trait "just works".  You may test to see if the necessary support is available 
by checking to see if `defined(BOOST_HAS_NOTHROW_COPY) || (!defined(BOOST_NO_CXX11_DECLTYPE) && !defined(BOOST_NO_CXX11_NOEXCEPT))` is true.

__header ` #include <boost/type_traits/has_nothrow_copy.hpp>` or ` #include <boost/type_traits.hpp>`
