Hi All.

I modified boost::any to adapt noncopyable object.

The boost::any can use noncopyable object like this:
_____________________________________________________________
    struct B : boost::noncopyable {
       B() : v1(), v2() {};
       B(unsigned int value1, unsigned int value2)
          : v1(value1) ,v2(value2)
       {};
       unsigned int v1, v2;
    };

    BOOST_AUTO_TEST_CASE(test02)
    {
       any test;
       //test = B();                 // compile error
       //test.reset<B>(10, 20);      // compile error
       test.reset<B, false>(10, 20);
       //any test2(test);            // throw
       //any test2;
       //test2 = test;               // throw
       BOOST_CHECK_EQUAL(any_cast<B&>(test).v1, 10);
       BOOST_CHECK_EQUAL(any_cast<B&>(test).v2, 20);
    }
