Ideally you should use -Werror and/or perform parameter checking.  a 2 
mod 3 number of parameters may be "invalid" but if you don't actually 
act on it your program cannot be verified.

Granted I never use -Werror as I don't care about a lot of the minor 
violations (.e.g. passing a long to %d in a homebrew behind the scenes 
test program).
