Regression failures: time, timetz, horology

I'm getting time, timetz, and horology regression failures in HEAD
on Solaris 9 / gcc 3.4.2. So are other machines in the build farm,
such as this one:

http://www.pgbuildfarm.org/cgi-bin/show_log.pl?nm=shark&dt=2005-05-26%2004:21:00

I'm getting the same regression failures shown in that link; here's
an example:

***************
*** 34,45 ****

SELECT f1 AS "Five" FROM TIME_TBL WHERE f1 > '05:06:07';
Five
! -------------
11:59:00
12:00:00
12:01:00
23:59:00
! 23:59:59.99
(5 rows)

SELECT f1 AS "None" FROM TIME_TBL WHERE f1 < '00:00';
--- 34,45 ----

SELECT f1 AS "Five" FROM TIME_TBL WHERE f1 > '05:06:07';
Five
! --------------
11:59:00
12:00:00
12:01:00
23:59:00
! 23:59:59.990
(5 rows)

SELECT f1 AS "None" FROM TIME_TBL WHERE f1 < '00:00';
