Which part doesn't make sense? Gentoo is doing similar work (and we're going to collaborate) just to be able to build the distribution with Clang 16 and later, which is going to make changes break C89 compatibility in the default configuration. I think GCC should eventually make this change as well because there are significant usability improvements possible. We won't have much of a choice once C2Y (not next year's release but the one after that) adopts auto for local type inference because that conflicts with a legacy C89 compatibility features still enabled by GCC by default. Doing this now means that “auto copy = strdup(source);” is not valid C99 to C2X, so we can detect it more easily. Once upstreams start using the auto keyword in C sources, this is going to be much harder. So right now is probably the absolutely last point in term when this whole thing is going to be a lot of work, but not *too* complicated. We will have to build some parts of the distribution in C89 mode potentially indefinitely, but some work is required to actually achieve that. We need to know which packages not to switch, and make sure that whatever mechanism we use actually works for their (often weird, old) build systems.
