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
