Actually it's not a fix to ppc64.  The earlier patch -broke- ppc32.  On
my iBook (assuredly 32 bit), backups just completely didn't work. Much
like the subject to bugs.debian.org/144986 .

The problem was that 64-bit filesystem was turned on. This makes off_t
64 bits.  This means that sscanf() must be changed to say %L instead of
%l when scanning into an off_t, or else big-endian architectures will
break, whether 32 or 64 bit.

I hope this clarifies.
