There are consequences you should be aware of...
This has several side effects that should be considered.
1. Structures will only be aligned to the size of the largest member.
i.e. structures containing only bytes will be byte aligned.
- structures containing shorts will be half word alinged.
+ structures containing shorts will be half word aligned.
structures containing ints will be word aligned.
