--- Comment #30 from Eric Botcazou <ebotcazou at gcc dot gnu.org> 2012-12-20 21:45:11 UTC --- > Almost nothing in GCC was added without precedent: Features were added because > backend X needed them or frontend Y needed them. To reject an extension just > because only one target needs it, is not an convincing argument. I totally disagree of course. You must first try to fit in the existing design and, only when that fails, you're allowed to propose extensions. > It's still not known why the ada / gnat stuff rebuilds stuff already there a > sectons time and at a stage ada / gnat don't expect such a build.

Yes, that's the crux of the matter.
