-current box build as of yesterday.
>Description:
Tar uses a int to store the bytes written count. This wraps at 2gig on the
i386 platform.
>How-To-Repeat:
Create a tar with --totals with a size over 2 gig, and watch what is reported
by tar at the end.
>Fix:
Change the counter to a u_quad_t using the following diff.
