Boost feature detection is wrong if the source is compiled with nvcc and clang as host compiler.
For example, move semantics can't be used with c++11 enabled.
#include <utility>
#include <boost/variant.hpp>
class TestClass
{
public:
TestClass() = default;
TestClass(const TestClass &) = delete;
TestClass(TestClass &&) = default;
};
int main() {
TestClass c1;
boost::variant<TestClass> v{std::move(c1)};
return 0;
}

everything works well.
