Still seeing large file problem

[Dale Amon <amon@vnl.com>]

Still having problems with 2G files. I can create a multigig file of 
zeroes file for my loopback, but I'm running into problems
when I try to open it. I wrote a small test prog that repro's
my problem and I've tried everything I can think of.

I'm hoping there is something obvious and stupid and easily fixed :-)

    perror (file);
