This is the only relevant discussion that I could find (now that
Jive is dead):
"[...] the kernel has no way of knowing that a 32-bit process was
compiled with large file support, only that it's a 32-bit process
vs a 64-bit process. So to do what you want to do, there's no good
way to use the more painless large file compilation environment,
and you end up doing what they other poster said and using
the transitional interfaces of the *64() form."
