   This is the correct way, assuming, you have header   
    included and E is an enumeration type

   I don't know what this should refer to. I'm quite sure that   
   std::EnumeratedType had never been proposed. A member type named   
   'underlyingType' would also seem quite odd given the

   This may very well be true (assuming that you have included the right   
   header). In this case you should try gcc 4.7 or greater. Surely gcc 4.8   
   has this type trait, but also note that this additionally requires to   
   set the compiler flag -std=c++0x (or -std=c++11 from gcc 4.8 (?) on).
