title: Eclipse CDT Error Parser for external gcc-based builder
body: <p>I understand that CDT 7 will have a regular expression error parser included, but I'm using CDT 6 now.</p>
  
  <p>I have an external CDT builder which just calls a shell script to trigger my build, (Jam-based).  The build uses GCC, and the errors and warnings are streamed to a Console view, but of course no error parser is looking at it so nothing appears in my Problems view.</p>
  
  <p>Is there a way to configure CDT to use it's GCC scanner on my console output to populate the Problems view?  The GCC parser is enabled, it's just not looking at my output.</p>
