Actually there wasn't any until I added it with the updated version!

That sounds like a reasonable solution: it's only one file after all, and I
think you probably really do want a POD type when building a singleton (but
just guessing on my part, I haven't looked at your code yet).

No problem, glad it was easily fixed,
