This might sound like a silly solution but I solved the same type of
problem a while back. I was working under unix using csh and so I
simply piped all my compile output through grep:
EX:
	CC foo.c |& fgrep warning

I had to use |& rather than | because I compile errors come through
stderr rather than stdout.

Hope this helps.
