Subject: DPMI

I went back and re-read my DPMI spec in hopes of supporting it, and as
part of my research tried some of the DPMI calls under Borland's
DPMIRES.  Bad luck - it's 0.9 also, and only 16-bit.  There's no point
trying to port go32 unless a DPMI 1.0 32-bit environment is available.

So, I've attached the test program (source and binary).  How about
folks who THINK they have a 32-bit DPMI 1.0 run this and post the
results?

Thanks,
DJ
