This is a known problem caused by a bug in the system header files that
IBM supplies.  There may by now be an update available from IBM to fix
their error, or you can manually patch the header files and recompile
Postgres.  See the list archives for details, eg
http://archives.postgresql.org/pgsql-ports/2005-05/msg00021.php
