wget file size overflow?

[Cornelis de Gier]

When downloading a 4370640896 byte dvd iso, wget 1.8.2 on fedora core 1 
reports a file size of 75,673,600 and uses this value to calculate the 
progress:

==> SYST ... done.    ==> PWD ... done.
==> TYPE I ... done.  ==> CWD /pub/os/Linux/distr/fedora/2/i386/iso ...
done.
==> PASV ... done.    ==> RETR FC2-i386-DVD.iso ... done.
