This change is not acceptable as it will break any place using __unused.
The short version is that the glibc header shouldnt' be doing this.
There are even comments in sys/cdefs.h about the compat issues. Most
other places seem to be using __unused1 or similar, which is perfectly
fine. Please submit a bug report against glibc...
