AIX Compilation Fun with 7.5 CVS

I was wanting to check out what was up with timezone handling with the
latest changes that were committed, as there had been some "biting" on
AIX. 

To wit, notice the default time zone on one of our AIX boxes:

bash-2.05a$ date 
Tue May 18 21:47:37 GDT 2004
bash-2.05a$ echo $TZ
CUT0GDT
bash-2.05a$ 

Ticket [redacted] describes what broke:
===========================================================================
Grr.  Led to errors because timezone was being treated as CUT0.

CUT0 may be _equivalent_ to GMT, but PostgreSQL isn't aware of it as
such, so inserts into the table epp_whois_cachemgr were failing with
much the same error message shown below:

template1=# select timestamptz(timeofday());
ERROR:  invalid input syntax for type timestamp with time zone: "Tue Apr
13 19:44:47.831616 2004 CUT"

1.  Changed ~/.profile to have PGTZ and TZ set to GMT

2.  Changed 7.4 instances to set the postgreSQL GUC variable   "timezone" to GMT, and SIGHUPped them
===========================================================================

I was hoping to check this out on "latest 7.5 CVS" in order that if
there be a need to get any "CUT" support added, we can get that in
_early_ in the test cycle.  If it remains borken, I'll update the AIX
documentation to at least give the user 'fair warning' that this can
be a problem.

But the AIX compile is breaking, on pg_dump.  Evidently there's some
conflict of symbol names, though it doesn't look like it's due to new
changes.  "finfo" seems pretty unique to AIX...
