I think you spotted the cause in the diff file:

Seems that the Suse folks did not trust the usage of the HZ
macro
that much. IIRC, HZ gives something like the kernel-internal
timer
resolution or similar, and specifiying this value outside a
header
file make some sense.
Compiling sanei_scsi.c from sane-backends 1.1.18 with this
patch
instead of the added #include line works fine.
