As someone responded, you can use the DPMI functions to allocate a
descriptor (though, of course, you get your own selector for it). You
can then use DPMI functions to set the 8-byte descriptor; since this
includes the System bit, etc, you can make a call gate. I'm not overly
familiar with the DJGPP libs, but I think they at least wrap the
allocate-descriptor dpmi function (int 0x31, function 0).

I haven't made a call gate with DPMI though, so I can't guarantee that
the set-descriptor function will pass when it is a call gate descriptor
you are making...
