Comment (by Klaas de Waal):

 Yes, using the packed attribute would also work. However, attributes are
 implementation/compiler dependent. Also there is memory alignment; in this
 case a 16-bit value is accessed at an odd address if the struct is
 Copying the bytes to the exact location of a byte array always works
 independent of the compiler, the compiler flags, attributes and underlying
 hardware architecture.
