Well, we never had an AIX 5.3 system when 8.0 was released, so didn't
attempt a compile.  Seneca just tried out a build on 8.0.3 on AIX 5.3;
it appears to be experiencing the same problem with initdb, and a
slight modification of the previous "fix" appears to resolve the
issue.

Can you suggest what further we might provide that would help?

It seems unlikely to be a compiler bug as the same issue has been
reported with both GCC and IBM XLC.  I could believe it being a libc
bug...

It would be terribly disappointing to have to report both internally
and externally that AIX 5.3 is not a usable platform for recent
releases of PostgreSQL...
