[cfp-interest 3555] Overflow, non-default rounding, errno is what?

[Fred J. Tydeman]

In reading 7.12.1 on "overflow", I do not see any words on what
happens to errno on overflow in non-default rounding.

Normally, if nothing is said, that means implicit Undefined Behaviour.
I assume we would want implementation-defined behaviour or
alter to ERANGE.
