title: how to set error message control to verbose in MinGW?
body: <p>What I read from gcc manual <a href="http://gcc.gnu.org/onlinedocs/gnat_ugn_unw/Output-and-Error-Message-Control.html" rel="nofollow">http://gcc.gnu.org/onlinedocs/gnat_ugn_unw/Output-and-Error-Message-Control.html</a> here is that the command line swich is <code>-gnatv</code>.</p>
  
  <p>But using this switch in MinGW gives: <code>cc1plus.exe: error: unrecognised debug output level "natv"</code></p>
