title: downgrade c++ compiler specefications
body: <p>I want to build a project that was originally built with <code>vs2010</code>, but I'm using <code>vs2015</code>(firebird SGBD). The problem is that I have lot of error messages due to the new features in <code>vs2015</code>, like i.e. <code>snprintf define</code>.</p>
  
  <p>Since my c++ skills are not that great, I am asking the following questions:</p>
  
  <ul>
  <li><p>Is it possible to use <code>vs 2015</code> and sort of <strong>downgrade</strong> c++ compiler and linker to earlier specifications ?</p></li>
  <li><p>Is it possible to do the same thing but with <code>vs online</code> ?</p></li>
  </ul>
