Milestone:  To Be Determined          |   Component:  type_traits
  Version:  Boost 1.48.0              |    Severity:  Problem

--------------------------------------+-------------------------------------
 Using Intel c++ compiler XE 12.1 the new c++11 strongly typed enum type
 isn't recognized by boost::is_enum. It is recognized by std::is_enum
 though:


 {{{
 #include <iostream>
 #include <type_traits>
 #include <boost/type_traits.hpp>
 //...
 enum class StrongEnum { first, second };
 std::cout << boost::is_enum<StrongEnum>::value << std::endl;
 std::cout << std::is_enum<StrongEnum>::value << std::endl;
 }}}


 The output is:[[BR]]
 0[[BR]]
 1

 Notice that the same bug is probably the reason why boost serialization
 for strongly typed enum's doesn't work either.
