Good point! It could be the case that SIZE_MAX is smaller than
LLONG_MAX. Honestly I don't know, but I would do what you are proposing
just to be sure: it is the safest option, and maybe the compiler will
take care of replacing the correct value at compile time. Way better
than leaving another bug lingering until someone else finds it again.

Best regards,
