A lot of work (so far) has been done to make sure that old djgpp
sources continue to work as is with the new djgpp environment (V2).
Thus, porting efforts now will not be wasted when V2 comes out.
However, V2 will have many performance and compatibility improvements
that may be worth porting to from the old djgpp sources.

It's likely that any system that can run V1 programs will be able to
run V1 programs, but the way we do this is by providing a DPMI server
that's based (loosely, by now :-) on the old go32.exe sources.

Some things in V2 needed to be fixed.  Specficially, anything that
didn't work in a Windows DOS box (V2 requires dpmi).  Graphics and
emu386 never worked in DPMI mode, and will not work in V2 without a
redesign.  I've gotten emu387 done; recent news is that GRX V2 is out
for alpha (don't ask for it - it's ALPHA!  BETA is when you get to ask
for it), so the graphics story is close also.
