I figured it would be something very much like that. Any chance of, say,
changing a variable definition from 32 bit signed to 64 bit signed, and
recompiling libc ?

Well, I think more than that, the assignment of the pointer to the file
probably failed, before it even got to *try* to find the end of the file.

Hmm, not very likely, unfortunately. And even if I could get access to
one, it would be quite a bear to transfer the files back & forth....

That's what I'm guessing, but I still haven't gotten to try it. Made a
brief attempt, but my hardware was not as cooperative as I'd hoped, so
I'll be trying again later.
Any chance I can split this thing into like, 2 pieces, and be able to
access half of it ?
