There's no fixed way of handling message field alignment - in theory,
it just works. In practice, gpre (and others, I expect) order the fields
in a message by size to minimize the impact of alignment.

All fields that are an even multiple of eight come first,
Then all fields that are a multiple of four,
Then two
Then the others.

Remember that Cstring is actually requested length + 1 and varchar
is requested length + 2.
