 Yeah, good idea.
 However, looks like the codes are still there.

If you compile with -Wall, every line gives a
warning. Either

warning: statement with no effect

or

warning: left-hand operand of comma expression has no effect

 I usually treat my codes succesfully compiled only when it gives
me no warining. :-)

 Any better idea?
