We should not remove lint until we have another program checker to
replace it with, but it is not itself very useful. And yes, I know
you've been working on it and I haven't been following the details,
but it will take far more than the time you've put in (and a ground-up
restructuring) to become even as useful as lclint or sparse, let alone
comparable to a state-of-the-art program checker.

It used to be that lint did not do this in a useful way (via
quantifier polymorphism) -- have you improved it?

I tried to check but running lint on a test file spews fatal errors
trying to read the system headers. If one adds -Ac11 and
-D'__attribute__(x)=' to avoid these, it does not complain about your
example, let alone any other more complex ones.
