Won't work in x86 --> x86_64 compat environments.

Thanks for catching it.

The aligned u64 trick probably will

#define aligned_u64 unsigned long long __attribute__((aligned(8)))

It just forces i386 to be aligned too.

Then use aligned_u64 instead of u64/__u64/u_int64_t in all user visible 
places. Similar for signed types.
