 rule::copy() and rule::alias() functions doesn't work when used on rules
 with inherited
 attributes.

   using namespace boost::spirit::qi;

   typedef std::string::iterator iter;

   rule<iter, int()> a;
   rule<iter, int()> a_cp;
   a_cp = a;           //compiles
   a_cp = a.copy();    //compiles
   a_cp = a.alias();   //compiles

   rule<iter, int(int)> b;
   rule<iter, int(int)> b_cp;
   b_cp = b;           //compiles
   b_cp = b.copy();    //fails to compile
   b_cp = b.alias();   //fails to compile
