I've seen similar symptoms with machines that have timezone troubles, or
more accurately timezone support which is not mapped correctly into the
Postgres timezone handling code. Could be that ./configure is confused.

Hi Henry. It is possible, and if I had my druthers I'd have an account
with group privileges to work directly in a patched Postgres tree
(perhaps the one you have already built). Any running servers would need
to be shut down to allow me to fire up debugging versions. Also, again
if possible, I would have access after-hours via one of my machines in
your domain. And if I can't see the problem right away (if I glance at
it a lunch time) then I wouldn't be able to look 'til next week.
