AIX has a compilation define, _LARGE_FILES, which "transparently"
enables 64 bit offsets and redefines subroutine calls to be their 64 bit
counterparts.

IBM has a document which talks about this and the problems that one
should be wary of: see "Writing Programs That Access Large Files" at

http://www.rs6000.ibm.com/doc_link/en_US/a_doc_lib/aixprggd/genprogc/prg_lrg_files.htm

The last time I was running INN 2.2 on an AIX system I decided to live
with 2GB files, so I can't provide feedback on how well this technique
works with INN.
