No need, once some patches go in, this will be selected and then it'll
get build coverage.

But the main thing is, this needs to be fixed - it's been causing build
errors for those of us carrying patches to use it, and thereby destroying
the usefulness of nightly testing.

Can we please get the fix into -rc?  Keeping the _regression_ _fix_ out
of -rc not only means that we're stuck with these build failures, but
also means that we create bisect problems for the next merge window.
