What do you recommend for DJGPP?

Is there a future for DJGPP in environments which are eliminating or have
eliminated DOS support?

As I see it, DJGPP only has a few choices:

  1) stay limited to DOS (and environments which support DOS boxes, e.g.,
older Windows and Linux with DOSEMU and FreeDOS)
  2) rework for portable DOS emulators such as DOSBox (I like, but DPMI
disabled.)
  3) rework for Windows console applications  (Pelles C, LCC-Win32, MinGW,
Cygwin...)
  4) rework for Linux (Why bother...? GCC toolchain.)
  5) create an "NTVDM" for Vista or port DOSEMU to Windows (NT's NTVDM was
supposedly DOS 5.0 with some patches...)

Various C compilers exist for Linux and Windows.  So, the upgrade path, IMO,
becomes environments where there aren't compilers and which support DOS,
either DOS boxes or DOS emulation.  I know DOSBox is intended for gaming and
supposedly has DPMI disabled, but I like the idea of DOSBox since it should
be free of v86 mode...
