We used to claim to support platforms using 'q' or 'I64' as the printf length modifier for long long int, by dint of replacing snprintf with our own code which uses the C99 standard 'll' modifier. But that is only adequate if we use INT64_MODIFIER only in snprintf-based calls, not directly with the platform's native printf or fprintf. Which hasn't been the case for years. We had not noticed, partially because of inadequate test coverage, and partially because the buildfarm is almost completely bare of machines that won't take 'll'. The last one seems to have been frogmouth, which was adjusted recently so that it will take 'll'. We might as well just give up on the pretense that anything else works, and save ourselves some configure cycles.
