--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-02-08 10:27:32 UTC --- Perhaps waste of space, but we have been including them there in the past, so removing them would be an ABI change. They could be made into @ as opposed to @@ symbols, so that nobody links against them (when using GNU versioning).
