> I'm now trying to track down some software for SunOS 4, starting with gcc so at least I can compile up some tools. IIRC it wasn't possible to compile gcc 2.95 for SunOS 4 for some reason, so I might try for 2.7 as I definitely remember using that at one time.

You'll need to check the documentation, there were some issues with
gcc when compiled with SunOS's cc (which was really meant to link the
kernel and not much more). So instead of the three-stage bootstrap
with 2 and 3 compared, you needed to do a 4-stage with 3 and 4
compared to ensure everything was fine. At least that's what I
remember. I also remember my first GCC on my first SS1+ being a 2.6.x
(can't remember the x), and using that later to recompile 2.7.2.1 and
later 2.7.2.3. I think I also got 2.8.1 at some point, but I don't
think I tried any later version on SunOS 4 (my primary SPARC system
was an Ultra 1 by then).

GCC timeline (<https://gcc.gnu.org/releases.html>) seems to match my
recollection, as I got the SS1+ at home somewhere in '95 IIRC, the U1
in late '98 or early '99.

Cordially,
