Oh I don't think they need any more incentive than they already have. gcc is
a prime example of non-conformance for non-conformance's sake.

C is a shitty unsafe language designed to be easy to implement. It's been
applied so inappropriately for so long, no amount of "standardizing" is ever
going to fix that. Given the miserable state of the "art" (gcc) it seems
ill advised to add more bloat and complexity to what is already a house of
cards on the verge of "The Big One". Better to keep static analysis tools
like various version of lint, splint etc. up to date with (optional?)
regression test-like suites of checks for known, bad code. Typical Linux
apps already compile with hundreds or thousands of warnings and everybody
already ignores them. Very few people are inclined to write correct, safe
code and of those people only a small percentage of them use C. There are
better things to spend your time on than improving C compiler diagnostics.
External tools are a better value and probably offer a better platform to do
those checks from than inside a burning house like gcc. I realize there are
plenty of C compilers around but unfortunately gcc is the most popular and
so are forks of it.
