Dave, it may help if you explicitly use a /G0 flag to msc.  That should
force the compiler to use *only* 8086 instructions.  It may very well be
that the compiler is doing some auto-processor-type-detect, and since
some significant set of (non-privileged) 80386 instruction formats will
actually work in 80386 V86 mode, it is incorrectly (semi-correctly?)
flagging the machine as an 80386.
