Well, it doesn't have to run absolutely *everywhere*, I just want to be 
able to pass it around for Linux distros without additional packages.  
And I think most 32-bit Linux filesystems these days are using either 
64-bit longs for off_t or at least getting to 4GiB-1 by making them 
unsigned, as ISO9660 does.

I haven't gotten that far yet :-)  genisoimage is erroring out before it 
touches the disk as soon as it sees the 4GiB-1 file in the list.
