Not a biggy.

In this case, the lint libraries will have to be changed:
[8:45:19] agc@db1 ~/lint 37 > cat a.c
[8:45:21] agc@db1 ~/lint 38 > make lint
lint -chapbxzF -i a.c
a.c(10): warning: function main falls off bottom without returning value 
lint -chapbxzF a.ln
printf returns value which is always ignored
[8:45:24] agc@db1 ~/lint 39 >
(Not that I'm against the change, merely mentioning that that is why some of
the utilities that I write have return's from main()).
