DPMI support, and hence Windows and OS/2 compatibility, was a new feature in
version 1.10; previous releases would not run under Windows or OS/2.

Strange.  At version 1.09, I could build GO32 with TC 2.0, but BC 3.1 was very
unhappy.  I submitted a bunch of changes to make it compile with either
compiler, and I think some of them made it into 1.10.  When I built 1.10 with
TC 2, it didn't work, but it did work when compiled with BC 3.1, even though
the compiler produced a lot of warning messages.  As far as the debugger goes,
I think DEBUG32 is getting too big for the small model.  I'm not sure what was
done about this for the standard release.
