IMHO its a code smell if your code doesn't work on 32-bit platforms. Remember, almost all 32 bit platforms are perfectly capable of working with 64-bit integers (just not as fast). But your code must be *correct* (e.g. use uint64_t), and not just coincidentally work on some compiler/platform but not guaranteed so by any C language standard.
