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.
Just my 0.02c

What about creating "old unix" version of djgpp. djgpp compiler is 32
bit "gcc" running in 16 bit DOS.
Perhaps DeJorie could help.

By "the old unixes" I assume that you mean things like V6 and V7
for the PDP-11.
Both gcc and GNU binutils already support PDP-11 targets, at
least to some extent, so you can already do cross development
targeted at the PDP-11.
Trying to actually host gcc on a 16 bit UNIX system is almost
certainly a completely futile and pointless exercise - it is many,
*many* times too big and I am pretty sure that it assumes at
least a 32 bit host - if you cut it down enough so that it fit it
isimply wouldn't be gcc any more.
I suspect that you would also find that most of "todays programs"
wouldn't fit either ...
