(My understanding is that the v20 and v30 are related just as the 8088
and 8086 are:  differing only in data-bus width.)

I have compiled various programs (microemacs v3.9e being the largest)
under TurboC's 80186/80286 option, and they work fine on my v20-equipped
Z-158.  The improvement in size and speed is small, but positive.

I've stopped doing that routinely, as I was giving code to others and
having it break for "mysterious" reasons.  Eventually I remembered that
80186 option ("oops. hehheh...")
