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. jeff
