#1421: ptr_map reference type is not a reference
--------------------------------------------------------+-------------------

     Type:  Bugs                                        |      Status:  new          
Milestone:  To Be Determined                            |   Component:  ptr_container
  Version:  Boost 1.34.1                                |    Severity:  Regression   
 Keywords:  ptr_map, ptr_container, reference, typedef  |  
--------------------------------------------------------+-------------------
 The "reference" typedef in ptr_map and also ptr_multimap is not defined as
 a reference. This can be easily demonstrated with the following code:


 {{{
 typedef std::map<int,int*> STDCTR;
 typedef boost::ptr_map<int,int> PTRCTR;

 bool isrefstdit = boost::is_reference<STDCTR::iterator::reference>::value;
 bool isrefstdval = boost::is_reference<STDCTR::reference>::value;
 bool isrefptrit = boost::is_reference<PTRCTR::iterator::reference>::value;
 bool isrefptrval = boost::is_reference<PTRCTR::reference>::value;
 }}}

 is_reference returns true for std::map, but false for boost::ptr_map.
 This was correct in v1.33.1, but is not in v1.34.1.
