This is almost "the most simple and stupid and nobody would get
confused" version, which I may actually be able to live with.
Unfortunately it will not get the "somebody by mistake uses 'oid'
and we can break the build no matter what compiler is used by them
before sending the patch out to the list".
Doing s/oid UNUSED2/oid_UNUSED/ without any __attribute__((unused))
would give that benefit to us, but that won't squelch compilation
with -Wunused which makes it a non-starter.
