I wasn't thinking about math issues, but rather struct field alignment/portability, and platform alignment requirements for basic types, issues. I'm guessing that it is all worked out by the compiler, so that makes the development of a compiler more difficult, if so, but how much more difficult? A simple example or description of how this is done would really be great. (BTW, this is definitely an area where I would approve of more language implementation complexity for the great strides in programming efficiency (and fun!) it gives).
