__unused has been used in glibc headers going back at least to 2.3, though 
maybe not in the particular headers affecting you.

There is cost associated with divergence between FSF glibc and EGLIBC that 
comes into play every merge, and I think it outweighs the benefit in this 
case.  If glibc were being designed from scratch or there were no upstream 
to deal with, then yes using __glibc_ in all internal identifiers would 
make sense, but that is not the situation here.
