Bah, thanks for the report. I hope I have time before to fix this today, otherwise, I'll need to do it when I get back from my travels.

Does this fix the issue?
From looking at it I'm fairly sure it addresses the build problem,
and semantically it looks correct as well, but I haven't had a chance to test it on my machine yet.
The build results above come from Mark Brown's automated build setup, so your testing is as good as mine in reproducing it.
