title: Is it possible to use C++11 ABI _and_ both cxx11-style and old-style strings?
body: <p>I have some code which is being built with GCC 5.3.1 without _GLIBCXX_CXX11_ABI set. Now, suppose I want to use both old-style and new-style <code>std::__cxx11::string</code>'s in the same bit of code . Is that possible? If so, how?</p>
  
  <p>Notes: </p>
  
  <ul>
  <li>I don't really have a good reason for doing this. I do have a not-so-good reason, but let's make it a theoretical question please.</li>
  <li>It's ok if the C++11 strings aren't called <code>std::string</code>.</li>
  </ul>
