My point is that proper programming discipline would have prevented the 
problem from arising in the first place.  It would be far more appropriate 
for kernel programmers to exercise such discpline than to treat them like 
babies, breaking well-known syntax in the process.

It seems trivial to pick up all potential min/max problems with the Stanford 
Checker in the case some programmer has been too clueless to think about 
their code as they write it.  A simple policy statement for users of min/max 
would have avoided this entire mess.

Not that I you're going to back down, it just made me feel better to get this 
off my chest ;-)
