That'd be ia64/ILP32, which isn't supported on Linux (or Windows,
though it is on HP-UX).

Yep.

Yep.

Certainly. I only wished Red Hat would be more
willing/interested/active in discussing such things on public mailing
lists.

No problem. I just wanted to make it clear why I think it would be
short-sighted to pub x86 libraries in /usr/lib on ia64.
