I would object. Now, if it automatically made demons fly from one's nose
if it detects an invalid return type, that I could go for.

If this is an added warning, then I'm actually all for it. I'd even
suggest returning NON-zero to make the error even more glaringly obvious.
(I know, your motivation is probably to get these skanky programs functioning
in shell scripts, rather than rooting out bad code, but the harder it is for
people to excuse bad programming habits with "well, it works on my compiler!",
the fewer bad programming habits we'll all have to put up with...)
