djggp relies on a DOS extender to run its 32-bit programs in a 16-bit
operating environment on a 32-bit machine. go32 is Delorie's own DOS extender
- OpenWatcom offers at least two other DOS extenders to pull the same kind of
trick.
If the purpose is to run a 32-bit Unix C compiler in a 16-bit Unix operating
environment on a 16-bit machine, it just won't work. I've never heard of
anyone ever running djgpp on a 286, either.
