I disagree with you. The new code is more practical than the old code, and as standards-conforming as the old code was. There's already a precedent for using numbers after __unused to avoid conflict, and so the new code is more consistent with the old code.

However, I agree that a patch proposing a more properly portable name would be better and should be encouraged. If Drepper were a little less hostile than his usual self, he would have been more amenable to a good cooperative solution like the __glibc_ solution.
