Subject: bug#2790: emacs 22.1.1 cannot open 5GB file on
64GB 64-bit GNU/Linux box
> There was an incorrect check that limited the size to INT_MAX/4
> (i.e. 512MB for systems where ints are 32bit). I've removed this check

It returns the correct value.

Yes, all this discussion is in this context. For 32bit systems, the
256MB limit kicks in long before we hit any of those problems.
