I honestly think that if we just test on linux with a single distribution, we're already covering most of the benefit. From memory there have been two rough classes of doesn't-build-anymore: 1) New optimizations / warnings. At least between gcc and clang, within a year or two, most of the issues end up being visible with the other compiler too. These aren't particularly distribution / OS specific. 2) Library dependencies cause problems, like the ssl detection mentioned elsewhere in this thread. This is also not that OS dependent. It's also not that clear that we can do something about the issues with a reasonable amount of effort in all cases. It's easy enough if it's just a minor configure fix, but we'd not want to backpatch larger SSL changes or such. Maybe there's also a case for building older releases with msvc, but that seems like a pain due to the msvc project generation needing to support a specific version of msvc. Greetings, Andres Freund
