it's broken whenever fortify source is used, but gcc-4.3.3 is more of an issue because it's on by default. however, this flag should not go in any dhcdbd ebuild considering the fix posted by Magnus to that bug is clearly correct. > But reading > tells me that I should not use this eclass to set compiler settings > directly.
