I don't think it matters. The define will be hw-specific so if long long and
int64_t is equally sized they can be used interchangably. The upside with
long long is that it works without any include files - but of course may not
work on pre-C99 systems.
I think there's a theoretical risk that long long isn't the same size as
int64_t since long long seems to be defined as "at least 64 bits" in C99.
