Ah, good point! How about...
`explicit comparison of an expression involving %select{an infinity|a NaN}0
constant will always return '%select{false|true}1' because
%select{infinity|NaN}0 will not be produced according to the currently enabled
floating-point options`
? It's a bit wordy, so maybe "use of infinity|NaN will always" is okay as well.
