If i give you a pointer to a field, that would mean you could add or
subtract bytes and legally get at any other member of the structure,
containing structure, etc.
I was told by Geoff Keating, and others, that this is not legal in C.
Have I been misinformed? That would be quite sad.
There was quite a bit of discussion of this internal to Apple, and no
agreement was reached. Geoff strongly takes the position you say;
Mike and I disagree. The standard seems unclear.
