3856	ambiguities with make_shared() function pointers with C++0x	Georg Fritzsche <georg.fritzsche@…>	Peter Dimov	"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]]
