I really wanted to give a try to FreeBSD... because I thought it was linux from "better" times... and then I saw they are tied to the tons of similar gcc extensions... and then I say to myself "why bother since it has the same major compiler dependency issue", better try to fix linux code base or start from there.
It doesn’t, though? Gcc doesn’t even ship oob, the project itself uses clang, and almost all packages are also compiled with the system c/c++ toolchain.
