They aren't. > in which case, there'd be no manual patching The patching was very easy since Debian has already backports for the used version and they apply cleanly. > needed and there'd be the benefit of > having all the bug and security fixes since FC25 went EOL be included too. Given that gcc (should) never touch untrusted input in our use case I'm unconvinced that updating it proactively is a good time investment. Or are there any concrete bugs you are thinking about? > If it works, gcc-6 should also build in FC23 with no additional upgrades > to libraries, so maybe it'd be worthwhile doing since gcc-5 is no longer > maintained by upstream gcc. As I already wrote that's not so easy. The gcc source package includes a bunch of libraries which are potentially used by a lot of packages (for example libstdc++). So a version jump there isn't a good idea. > If wanting to backport gcc-7.3 to FC23 and FC25, the only other library > that would absolutely be needed to be upgraded is isl and isl-devel. You > could use the FC26 src rpms for both isl/isl-devel and gcc for that. FWIW, gcc 7.3 built fine for me without updating isl in Fedora 25. Anyway we are not going this way (see other mail).
