It is widely used in the ports tree to determine whether a particular patch should be applied. (actually, that's precisely the reason why __FreeBSD_version was introduced, and it lived in userland for a while before eivind@ moved it into the kernel in 1998) > Sometime it is used to mark the point where big changes hit the tree, > possibly not related to interface change. Bumps are cheap, better one too many than one too few. > Also, __FreeBSD_version denotes the kernel "version". No, it has been bumped for libc changes in the past.
