Sorry to nitpick, I hope this isn't too annoying -- do you have an example of an implementation (platform, compiler, whatever) where this statement is true? Some C compilers see it differently, because they think that since padding is not defined by the C standard they can do what ever they want even on platforms where it is defined. I am genuinely interested to know of one like that. It wouldn't be a very useful C99 compiler, because C99 says that it is OK to do this, and lots of C99 code does this. But I would like to know about the existence of an implementation like this for use as an example in the future when talking about this topic.
