And I was pointing out that, no, they don't *have* to be defined for
generic code to work, since is_bounded is a compile-time constant,
making it possible to not compile the max()- and min()-using code when
it has value false.

The standard seems to only talk about fundamental types having
specializations, so it's unclear to me whether members that are not
"meaningful" are meant to be provided or not.
