/**
* Workaround for documentation parser limitations
*
* Current documentation parsers (sphinx under Doxygen) don't seem to
* understand well unnamed structs / unions. A workaround is to make
* the parser think there is something like a struct/union/enum name
* that is actually something with no effect to the compiler.
*
* Current choice is to give it a 1B alignment. This basically tells
* the compiler to do what is doing now: align it wherever it thinks
* it should, as a 1B alignment "restriction" fits any other alignment
* restriction we might have.
