See bugs 14030, 26732, 48091, 64526.  Not sure how many bugs in this area 
are genuinely different - I suspect a single bug could be considered to 
cover the whole area of checking arguments to K&R functions (with 
warnings, not pedwarns or errors, for bad calls), as long as all different 
cases are properly covered with tests added for any fix.
