AIX 6.1 does not have O_NOFOLLOW so this code fails to compile. 
configure should probably check for O_NOFOLLOW support.

src/lib/krb5/rcache/rc_dfl.c
   +102
   +103      fd = open(fname, O_CREAT | O_RDWR | O_NOFOLLOW, 0600);
   +104      if (fd < 0) {
   +105          ret = errno;
   +106          k5_setmsg(context, ret, "%s (filename: %s)",
   +107                    error_message(ret), fname);
   +108          goto cleanup;
   +109      }
