Hi,

Also the c-family/ part of it, or just the c/ part? The latter I admit is not very nice (another ugliness is that we want the parameters before doing standard argument promotions on them).

The latter, the latter.

Unrelated, but I can't resist, it would be great if for 4.8 we could
also eliminate the duplicate diagnostics noticed in 28656, does that
look doable?!? If you have hints I could also do it, in practice.

The problem there is that memcpy (and I guess many others) ends up with more
than one nonnull attribute.  Untested patch in the PR now.

Thanks!

Paolo.
