In my experience the warning is more trouble than it's worth in Emacs source 
code, as its signal-to-noise ratio is too large there. There are no free lunches 
in software development, and this particular lunch goes waaayyy over budget.

Although I also would like to go back to 1975 and whisper advice in Thompson & 
Ritchie's ears, it's a bit late for that now. Besides, they would have disagreed 
with me anyway, and with you too. (Some years later I argued with Ritchie on the 
topic of C's integer widths and promotions, and failed to convince him.)
