The only other thought is that structure packing isn't working properly
for you. To ensure that all the header fields are correctly positioned
we try to force the compiler to pack structures and not put padding in
between fields to align them to their "natural" boundary. If your
compiler wasn't doing this properly, or the port you're using hasn't set
up the PACK_STRUCT... macros properly, this might explain fields being
offset.
