Fixed IRIX warning:

"./rdata/in_1/a6_38.c", line 259: remark(1552): variable "octets" was set but
          never used
by using UNUSED() on this stack variable.  I didn't take it out altogether
because this function is not yet finished, but someone was starting to
do some work on it and I didn't want to undo that.
