Hm.  I'm not sure about the "ignore" option.  I'm not a fan of adding
lots of options, it just makes things that much more complicated to use
and test.  Is it important to allow these checks to be completely
ignored?  If the default is to leave them as warnings they won't cause
make to fail or change what it will build.
