title: If ARM compiler has similar option for -Werror
body: <p>I know <code>gcc</code> has an option <code>-Werror</code>, which can stop compile if there is an warning, if <code>armcc</code> has similar option, because I want to have a good code quality control in compile level</p>
  
  <p><strong>additional info:</strong></p>
  
  <p>I use <code>armcc</code> 2.2 build 616, I consult ARM, it said <code>--diag_error=warning</code> was add ONLY for <code>armcc</code> 4.0 or later</p>
