If you're confident that this will work, I'm fine with it.  Like I said,
I didn't dig deep into the matter.  I was just caught by the following
quote in the above reference:

"This macro should only be selected if the system provides mechanisms
for handling large files. On 64 bit systems this macro has no effect
since the *64 functions are identical to the normal functions."
