OK, I am focusing on AIX now. I don't think we can go down the road of
saying where large file support is needed or not needed. I think for
each platform either we support large files or we don't. Is there a way
to have off_t be 64 bits everywhere, and if it is, why wouldn't we just
enable that rather than poke around figuring out where it is needed?

Also, I have the open item:

Fix AIX + Large File + Flex problem

Is there an AIX problem with Flex?
