title: One MinGW, many GCC versions - how to do it?
body: <p>Is it possible to have <strong>different</strong> GCC installations working with <strong>one</strong> MinGW installation?  </p>
  
  <p>By MinGW I mean the common base which is always needed regardless which version of GCC compiler we're going to install and use;</p>
  
  <ul>
  <li>MinGW runtime </li>
  <li>binutils</li>
  <li>make</li>
  <li>MinGW API for MS-Windows</li>
  </ul>
  
  <p>and many other components which are part of MinGW but are not even required by GCC.</p>
