------------------------------+--------------------------------
 64-bit macOS and BSD are LP64, which means that their ints are 32 bits.
 This makes Tor's hash tables 32 bits, reducing their security.

 This issue also occurs on 32-bit systems, where using uint64_t might be
 slower. I don't know if speed matters, as siphash is 64 bit anyway.
