oops, yes un-necessary.

I prefer to pack things explicitly rather than rely on ABI padding. My aim is to be able to document the interfaces separately from the C source, and that will include knowing the offset of each field, and that's easiest if the compiler isn't automatically helping by paddin things unexpectedly. If PACKED is too painful on a particular arch you can always stub it out -- it's only a macro after all.
