As a top-of-the-head suggestion, why don't you send the stderr to a file
and run a sed script on it to remove those errors you're no longer
interested in.  Telling the compiler to avoid warnings on specific line
numbers or specific conditions wouldn't be much easier and you'd stand a
fair chance that something useful might be unintentionally hidden.
