I don't have a gitlab account, so I'm commenting here.

I believe RCS was initially used circa 1992 on the FSF machine which
held the canonical GCC sources.  But I'm not aware of anyone still
having a copy of the old RCS ,v files.

THere's a slight chance we've got the old gcc2 snapshots in the Cygnus
CVS tree (assuming I could still find it) -- we may have imported the
snapshots onto CVS branches -- I can't really remember anymore.

FOr old releases, the best resource I know of is:

ftp://gcc.gnu.org/pub/gcc/old-releases

That has stuff all the way back to gcc-0.9, circa 1987.  It's nowhere
near complete.  You'll also find that in that era things were split up.
ie, the C++ compiler & runtime were separate distributions from the C
compiler & code generator, similarly for the old g77 compiler, gnat,
etc.

You may find other nuggets in there.
