Or should `ReportWarning` be extended to accept either kinds of flags, until the implementation is settled on either of them?

If there are no suggestions on a way to go here, I'll push a fix within a couple hours, that fixes compilation - probably switching the newly added code to `std::once_flag` as that's what the existing function takes.
