^^^^^^^^^^^^^^^^^^
The binutils-2.9.4 assembler has better syntax checking than previous
versions of gas, and exposes some shoddy assembly in in2000.h
This will fix it, without causing problems for old assemblers. You could
also just zap the %%dx from the insw and outsw instructions, but this way
we show the segment/index regs used.
