If you're calling make_pair with an explicit template argument list e.g. 
  pair<string&, string&> p = make_pair<string&, string&>(s1, s2);
then that won't work in C++11

Just construct a pair directly, it's pointless to use make_pair if you don't
want to deduce the argument types:

  auto p = pair<string&, string&>(s1, s2);
or
  pair<string&, string&> p(s1, s2);
