The code would never have worked at all if that were the case (since
text* is not like char*). I suspect some subtler portability issue in
Geoffrey's glue functions. It seems unlikely that moving from PG 7.4.13
to 7.4.16 would in itself have exposed such a problem, but the update in
operating environment from RHEL3 to RHEL4 might've.
