Agreed! These days it seems there is a competition for the stupidest warning between compilers, and we've reached the point where working around them manages to introduce real bugs :-( I predict we'll soon see warning such as "this comment looks like valid C code, if you really intended to comment it out, use #if 0 instead". Oh well, let's hope I have not given a new idea here... Willy
