All of the Windows machines except bowerbird and hamerkop have now
reported in on this change, and none of them are showing any warnings
about isnan. I'll be surprised if bowerbird does, since it's an
intermediate version of MSVC between ones that already reported.
hamerkop seems to be the oldest MSVC version we have, so conceivably
it'll issue a warning; but unless it fails outright I'd be inclined to
ignore it.
