I use lint fairly often, and this feature has caught bugs a couple of times
for me...

...if someone can't get access to an ANSI compiler, what makes you think
they're going to d/l unproto, and run it?  (It makes mistakes sometimes..
__P() does not).

...Oh, I dunno... a long time ago, I ported and used some NetBSD code

I'm going to put my Core hat on for a sec:

	C9X seems like they want to change the world, with no thought
	to backwards compatibility.  With that attitude, how can the
	committee even expect it to gain any momentum.  If it doesn't
	gain momentum, why should NetBSD jump on it?

...and to put my Software Developer hat back on:

	Sounds like a language I don't want to program in.  So much
	for reusing legacy code.
