using the appropriate (unsigned) format specification. This prevents integer overflow when ULLONG_MAX and (on some architectures) ULONG_MAX are used to initialize an intmax_t and then displayed as the signed value -1. (A different approach was suggested in the bug report, which I did not use.) If other limits are defined to be unsigned, they could be moved here. PR: 164049 Reported by: Marcus Reid
