Yeah. prairiedog and gaur are both frankenstein systems: some of the
software components are years newer than the underlying OS. So I don't
mind changing them further; in the end they're both in the buildfarm
for reasons of hardware diversity, not because they represent platforms
anyone would run production PG on. On the other hand, those AIX animals
represent systems that are still considered production grade (no?), so
we have to be willing to adapt to them not vice versa.

I'm only concerned about whether the all-zero value causes any
significant degradation in test quality. Probably Peter G. would
have the most informed opinion about that.
