--- Comment #15 from Kai Tietz <ktietz at gcc dot gnu.org> 2013-01-25 23:53:37 UTC --- Issue was fixed on trunk. As far as I know should rawhide Fedora have fixed that issue already. Nevertheless we could define the broken-vsprintf macro based on header-version. I will come up with a patch for that.
