You had the right idea here, and I think we can make it work without
having to upgrade AIX.  The posixio.c module requires not only ANSI but
also POSIX defines, so you need the -D_POSIX_SOURCE flag on compile
lines.  To do this:

  1.  rm config.cache
  2.  define CPPFLAGS as "-D_POSIX_SOURCE -DNDEBUG" in your environment
      before invoking configure.
  3.  make clean
  4.  ./configure
  5.  make all test install

Please let us know if this works, since we don't have an AIX 3.5 system
to try it on.
