Statement unlikely to be reached at

    (W exec) You did an exec() with some statement after it other than a
    die().  This is almost always an error, because exec() never returns
    unless there was a failure.  You probably wanted to use system()
    instead, which does return.  To suppress this warning, put the exec() in
    a block by itself.
    
	(Maybe you meant system() when you said exec()?)
