title: How do I build Boost 1.55 with MinGW?
body: <p>I have downloaded Boost 1.55 and MinGW.</p>
  
  <p>The console answers me that I haven't any command.
  I can't understand how to bind two paths and activate the GCC compiler.</p>
  
  <p>P.S.: If I build boost with Microsoft's compiler I will have about 8 mistakes with error 3861!!</p>
  
  <p>How can I build it?</p>
