Would it be worth supporting a 4-stage bootstrap, with stage 0 being
built from older gcc sources? We could include a contrib/ script that
downloads sources for gcc-4.7 or whatever and patches it to build with
modern as well as old compilers. (When I tried gcc-4.7 last week,
I needed a couple of tweaks to get it to build.)
Not that I'd have time try that before GCC 9...
Thanks,
Richard
