yes - that's the plan.  as i recall, Kalvis published a separate
set of diffs for gcc12, though many of the fixes remain common
between them IIRC.  (it's been a while :).

some of the changes are not in vax-specific code (though it is in
code not used by more than half the GCC ports we use.)

i've been trying to find time to test those changes enabled for
non-vax, to see if any other bugs we've seen there are fixed.
(this is not working so well.)
