Is this now on e.g. PowerPC etc? Or also on x86? But in any case, LGTM.

I saw this building CheriBSD, and I think it affected almost all architectures.

Ah, I thought maybe now that the StrictFP stuff is operational we might finally get some #pragma FENV_ACCESS support, but it's probably a whole other can of worms...

Looks like the warning is not triggered for x86, only other architectures. That indicates that the pragmas might actually be implemented now.
Should I restrict the -Wno-error to non-x86?
