--- Comment #3 from Eric Gallager <egallager at gcc dot gnu.org> ---
There already is a warning from -Wsign-conversion for it:
$ /usr/local/bin/gcc -c -Wall -Wextra -Wconversion 96460.c
96460.c: In function 'f2':
96460.c:4:12: warning: conversion to 'long unsigned int' from 'int' may change
the sign of the result [-Wsign-conversion]
4 | return i % 16;
