OK for mainline.

For the release branches, it seems to me that this introduces a
potential if rather unlikely regression from the gcc_unreachable call.
And this is not a significant user visible problem.  So I'll say that
it is OK for the release branches without the gcc_unreachable--just
return 0 if the UIDs are the same.

Thanks.
