The warning appears in W=2 builds. I had another way to silence it by using diagnostic control macros, but those macros were not accepted. Using a single designated initialization also silences it.

Oh well. I think the earlier version was slightly cleaner, but if it
helps people to catch real bugs better I'm happy to apply it.
