I would have thought the ideal non-automated C way of doing this would
be to define a wire format that is convenient for manipulating
endianness (eg, no packing) and manually stuff this on the way
out/unstuff on the way in. Far less dangerous than trying to
manipulate packed data.
Sometimes the transport mechanism forces you to use the same length
for every component -- eg, X properties, where you can choose 1/2/4
byte length and the server byteswaps for you.
