I'd prefer a patch that just gives a warning for unknown -W option. It 
would be just like if the detection was really bad. Doing the same for 
other options would be more risky IMHO. That would avoid rewriting the 
Makefile to only add switches to CFLAGS that are supported by the 
compiler as it should have been done ;-) (no blame, we all do this).
