Summary: static assert for boost::python::make_constructor

Initial Comment:
You get a static assertion when using
boost::python::make_constructor together
with the call policy
return_value_policy<manage_new_object>()

Test case:
=====================================================
#include <boost/python.hpp>

namespace Test {
  using namespace boost::python;

  class Foo {
  };

  Foo *fooCreator() { return new Foo(); }

  BOOST_PYTHON_MODULE(Test)
  {
    class_<Foo>("Foo")
      .def("__init__", make_constructor(fooCreator,
return_value_policy<manage_new_object>()));
  }

} /* namespace Test */

Failure:
=====================================================
/usr/include/boost/python/make_constructor.hpp: In
instantiation of
`boost::python::detail::constructor_policy<boost::python::return_value_policy<boost::python::manage_new_object,
boost::python::default_call_policies> >':
/usr/include/boost/python/make_constructor.hpp:150:  
instantiated from `boost::python::api::object
boost::python::detail::make_constructor_aux(F, const
CallPolicies&, const Sig&) [with F = Test::Foo*(*)(),
CallPolicies =
boost::python::return_value_policy<boost::python::manage_new_object,
boost::python::default_call_policies>, Sig =
boost::mpl::vector1<Test::Foo*>]'
/usr/include/boost/python/make_constructor.hpp:236:  
instantiated from `boost::python::api::object
boost::python::make_constructor(F, const CallPolicies&)
[with F = Test::Foo*(*)(), CallPolicies =
boost::python::return_value_policy<boost::python::manage_new_object,
boost::python::default_call_policies>]'
boost-python-test.cpp:14:   instantiated from here
/usr/include/boost/python/make_constructor.hpp:106:
error: incomplete type `
   boost::STATIC_ASSERTION_FAILURE<false>' does not
have member `value'

Expected Result:
=====================================================
Should compile
