With old AIX versions there seems to be a problem with gcc not liking the system headers (see recent thread), but we know 5.2 builds PG OK with either gcc or cc; there are a couple of 5.2 machines in the buildfarm. I'd go with the latest system release if I were you, barring very concrete reasons not to. regards, tom lane
