 Trying to store a function pointer to make_shared<Arg1> results in
 ambiguity errors in gcc (4.3.) with C++0x support being enabled.

 The following:

   typedef boost::shared_ptr<int>(*FP)();[[BR]]
   FP fp = boost::make_shared<int>;

 leads to:

 error: converting overloaded function ‘make_shared’ to type ‘class
 boost::shared_ptr<int> (*)()’ is ambiguous[[BR]]
 boost_1_41_0/boost/smart_ptr/make_shared.hpp:100: error: candidates are:
 boost::shared_ptr<X> boost::make_shared() [with T = int][[BR]]
 boost_1_41_0/boost/smart_ptr/make_shared.hpp:138: error:
 boost::shared_ptr<X> boost::make_shared(Args&& ...) [with T = int, Args =
 ][[BR]]
