I found this:

I wasn't really aware of 6.3.2.1, but after reading it and re-reading
6.5.1.1, I think I agree with his "model 0" interpretation: no promotion
or conversion.

I don't have a standards-based reason for this, though; just my belief
that _Generic was omitted from 6.3.2.1 by mistake.

That's an amateur opinion though.  I think it would be better for you to
say what you think.


I thought I was implementing "model 0", but the test program he posts
shows differently.

I'm happy to try to fix that up, but I'd like your guidance as to the
proper direction.
