--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Thorsten Glaser from comment #5) > Hm, unsure. These versioning scripts are pretty much recent GNU stuff. Recent as in the last 10 years maybe. But not in the last 5 years. Also they are supported in Solaris and even Darwin too.
