Usually I'd say 2.95.2 is the theoretical minimum. There are still
a couple of machines around with only a gcc 3.3 or 3.4.6.

A few groups (Haiku, OS/2 porters) used to stick with old compilers for a
lnng time.
- On Haiku, gcc 2.95.3 is the default, but people can also use a gcc-5.4 port [1].
- On OS/2, there is a gcc 7.2 meanwhile. [2]

These mentions of old compilers in lispbibl.d don't really cost many
lines of code. But it seems safe to remove support for versions < 2.95.2.
