The other thread recently referred to:

was mostly about how AIX's choice that alignof(double) < alignof(int64)
breaks a whole bunch of assumptions in our code. AFAICS we've done
nothing to resolve that, and nobody really wants to deal with it,
and there's no good reason to think that fixing it would improve
portability to any other platform. So maybe there's an adequate
case for just nuking AIX support altogether? I can't recall the
last time I saw a report from an actual AIX end user.
