--- Comment #15 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-01-28 08:19:43 UTC --- Because -gstabs etc. are still supported on most of the primary and secondary targets, and (to my surprise) some projects are still using it (I believe e.g. some Mozilla builds do as their bugreporting system only supports STABS, not DWARF). STABS hasn't been deprecated, so we can't just remove that support for 4.8 easily, yeah, we should probably deprecate it and remove later on.
