Thanks for the message!  I think this is an important patch, hopefully someone
can review it at some point.  Although I suppose this should be fixed on the
hdpmi32 side too, so newer hdpmi versions are compatible with old djgpp
programs, and new djgpp programs can work with older hdpmi versions.

As for why someone might want to use hdpmi instead of cwsdpmi, the simple
answer is speed - on the few functions I benchmarked, it's over 20 times
faster.  That can add up on things like allocating memory or PM-RM switches.
Plus it implements more (almost all) DPMI 1.0 functions.
