Alignment attribute specifies members' alignment if it is inside
structure and structure alignment if it is placed outside it. In
case of S2 and S3 u member is placed without alignment and both
structures contain 2+4 bytes, but because structures themselves
are not specified with align() attribute, they are aligned to
default 4 byte boundary and contain additional 2 trailing bytes.
S4 is specified as having no alignment, so it's size is exactly
2+4 bytes.
