Before we go down this rabbit hole -- Vinson said it doesn't support
#pragma once. He didn't say it caused problems. I don't expect it is,
since we're already using it and have been for a long time.

It probably just means that you have to to #pragma once along with the
standard #ifndef ... #endif wrapper.
