Yeah. My Intel Mac buildfarm animal (longfin) has been showing this
for some time, but there's no corresponding warning on its ARM Mac
brethren (sifaka/indri). I doubt it's worth fixing just to get
rid of the warning. Although if a fix arises organically out of the
nearby thread about popcount refactoring, that would be okay here...
