My opinion on this is that alignment inside a file is just as 
important/useful as alignment in memory since the file may be memory 
mapped, and then all the limitations which apply to memory access also 
apply to file access via that memory map.

It is not necessary to declare that at the value needs to be 8 bytes 
in order to accomplish desired alignment since you can simply add in 4 
unused 
pad bytes.
