compile todays programs. The old C compilers can be kept for safekeeping as
they don't work much anymore.
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 ...
