// This file illustrates how padding is handled: alignment
// requirements can lead to the introduction of padding, either before
// fields or at the end of the structure as a whole.
//
// It avoids using u64/i64 because on some targets that is only 4-byte
// aligned (while on most it is 8-byte aligned) and so the resulting
// padding and overall computed sizes can be quite different.
