It's not the compiler version that's at issue.  It's that the system
headers in F-11 don't define struct ucred unless you defined _GNU_SOURCE
someplace.  RHEL-5 is a lot closer to the build environment 7.2 is
expecting.

7.3.x does still build on F-11, so it probably wouldn't be that hard
to make 7.2.x go if someone with familiarity with the sources were
motivated to do it.  But for a novice it'd be a mighty un-fun task.

I'm personally kind of wondering what the OP's system was before.
Red Hat never shipped PG 7.2 at all, so it probably wasn't RHEL
or CentOS or Fedora.
