file sizes shown incorrectly for large files under Windows

[Chris Moore]

In a dired listing of a file I see:

  -rw-rw-rw-   1 Chris    root 386551808 08-22 06:38 Disk Image (C).DIM

but the file is much bigger than that.

Using an eshell buffer I see the same information:

  h:/ $ ls -l *.dim
  -rw-rw-rw-   1 Chris    5        386551808 Aug 22 06:38 Disk Image (C).DIM

The native Windows dir command shows me the correct size:

  22/08/2003  06:38    26,156,355,584 Disk Image (C).DIM

It seems that both problems stem from the use of the file-attributes
function:

  (nth 7 (file-attributes "Disk Image (C).DIM"))
  => 386551808.0

file-attributes uses a floating point value for the filesize because
it's too big to be stored in an integer, but it still gets it wrong.
