Good job. However, as I can see this fix requires explicit type
conversions in many places. I am almost sure that next time when
somebody improve the code then he/she will forget about this needed
type conversions. So maybe it is worth creating new struct which
will have xch_ctxt_offset as off_t instead of unsigned long and
do this conversion once somewhere.
