How so, "confused"? The documentation says it should be defined, it doesn't
say that it should be defined as empty. What goes wrong if it's defined as 1
rather than empty?
The documentation is also somewhat misleading, because it says to define it if
the hardware has no divide instruction. The more accurate statement is that it
should be defined if the hardware has no 64 / 32 bit divide hardware support.
pdp11.h points this out in a comment, because most pdp11s do have divide
instructions but those are for 32 / 16 bits.
