Oops, I saw what the patch was and assumed you (Jim) sent it. Sorry for 
the confusion, Paul! (...that would explain why you mentioned a 
different platform ;-).)

As Jim notes, AIX gives (unsigned)-2 (i.e. UINTMAX_MAX - 1), not 
(unsigned)-1 (UINTMAX_MAX), so the previous patch won't actually fix the 
problem on AIX.

Adjusting
  if (total != UINTMAX_MAX)
to
  if (total < UINTMAX_MAX - 1)
should suffice.
