The idea of having lint use constant format strings to check types and
arg counts is a great one.  I have wanted to do this for many years as
argument types and counts for printf and its buddies are one of my more
frequent errors.  Could we come up with a system that does not require any
includes or modifications to the code to do it?  This would be great!
