--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Invalid as explained. There is no ADL for fundamental types, so you cannot
customise their behaviour. 

In general, you should not attempt to customise behaviour for types you don't
own. The behaviour of std::strong_order for float is fully specified by the
standard.
