Wasn't the point that 32 bit AIX as a whole hasn't been supported for a
couple years now? My willingness to expend effort for that is rather
limited.
I mean I'd otherwise ok with a PG_FORCE_DISABLE_INLINE flag that takes
effect in c.h or so. That could easily be set in src/template/aix. Might
also be useful for investigatory purposes every couple years or so.
