//  MACRO:         BOOST_NO_CXX11_SMART_PTR
//  TITLE:         C++11 <memory> has no shared_ptr and unique_ptr
//  DESCRIPTION:   The compiler does not support the C++11 smart pointer features added to <memory>

#include <memory>
// Hash functions for shared pointers should be in <memory>
// but with some std lib's we have to include <functional> as well...
#include <functional>

   std::unique_ptr<int> upi(new int);

   spi = std::static_pointer_cast<int>(spi);

   std::hash<std::shared_ptr<int> > h1;
   std::hash<std::unique_ptr<int> > h2;
