Thanks for the clarification. That all seems consistent, and I think I
can now (mostly) understand how the POSIX error values relate back to
the IEEE 754-2019 specification.
I do wonder if POSIX will add the new minimum/maximum operations; they
seem more like what I expect wrt NaN handling than the existing
minimumNumber/fmin maximumNumber/fmax operations.
Any other concerns about the testing values I'm using? Should we adopt
the newlib patches necessary to have it pass those tests?
