I'm sorry OpenBSD also cranks libc versions whenever needed. And it depends on what changed, if it'll run on an old kernel. Since it links against a fixed version, keeping it running involves recompiling or some trickery... So basically executable are mostly only ever good for 1 stable release. So don't throw away your source code, you gonna need it in 6 month.
