I can confirm that these are fixed.

Should the type be a struct?
I think ONCE_FLAG_INIT needs to be a compound literal, not an
initializer, at least that's how I read the standard (âwhich expands to
a value that can be used to initialize an objectâ).

Missing indentation of the #define. The manual could mention that for
C++, C++11 or later needs to be used to get the thread_local keyword
(not the macro).

I'm fine with leaving it as is.
Thanks,
