This sounds very interesting with respect to the recent thread about
near pointers in a DJGPP DPMI environment. Can you give us more details
about how DOS4GW accomplishes this? Can you confirm that it is able to
get this kind of linear mapping under any DPMI 0.9 provider (like the
DOS box of Windows 3.x)?

Thanks
