Now it's pretty much clear why this doesn't work.  You should use
_go32_conventional_mem_selector() instead of 0 as the first arg
of farpeekX and farpokeX.  (I hope I get that long name right, but
look in the Info manual of libc.a (type ``info libc.a'' and look
under _go32_XXXX stuff)).  The first arg to those routines is a
selector, not segment, and DOS memory is *not* pointed to by
zero selector!
