In general we don't care about the standards. Saying "asinh is in C89 so
it's guaranteed to be available" doesn't make sense, nothing is
guaranteed. There may or may not be a system out there that doesn't have
it, no matter what the standards say.

So in principle we add checks as we find systems that require them, and
we don't remove them because there's no easy way to check that they
aren't still needed somewhere.
