That's why I also liked the idea of just adding a warning.

The only remaining potential for a debate would be whether this
warning should always be enabled (I think so, because it's a usage
error, according to the description of the always_inline attribute),
or made optional.  In the latter, another -Wxxx option would be
needed, and I guess it takes also some energy to convince everybody to
at least include it into -Wall then.

I don't know whether I'm motivated for that though. ;-)

Never trust an operating system you don't have sources for. ;-)
