I guess this is an age old problem of backwards compatibility. As I have
understood it, originally in C, long was intended to be the largest
integer type supported by the compiler, which was usually 32 bits. When
64-bit arithmetic was introduced, long couldn't be extended to 64 bits
for fear of breaking too much old code, and thus long long was invented.
And now intmax_t is suffering more or less the same process as long...
