    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 aligned.

       This means structures should be padded to a word boundary if
       alignment of 32 is required for byte structures etc.

    2. A potential performance penalty may exist if strings are no longer
       word aligned.  GCC will not be able to use word load/stores to copy
       short strings.
