Pretty much the same issue then. Sounds like the job didn't get
finished. svn_filesize_t works for me. If we think it's too much judo
we can always typedef svn_offset_t to svn_filesize_t.

Well I didn't see a motivation for a 64-bit int. All line_no is a
counter that gets incremented with every call. I have no problem using
a 64-bit int or doing the tiny (and I mean tiny) workaround to make it
work nicely on various perl versions. I'll be more than happy to
implement it as a apr_uint64_t if that's what people want.
