This will cause ACK libc to provide int64_t as long (instead of long long) on LP64, if we ever get such a platform. LP64 would have 64-bit long and 64-bit long long, so int64_t might be either type. For example on amd64, int64_t is long in NetBSD libc, and long long in OpenBSD libc. Support for long long in ACK remains incomplete (no printf "%lld"), so it seems better to prefer long where possible. Also, int64_t being long before long long is more consistent with int32_t being int before long. Put suffixes on the values of INT32_MAX, INT64_MAX, and related constants, so they have the same types as int32_t and int64_t.
