Right. Chapter and verse: section 126.96.36.199 (ANSI) / 188.8.131.52 (ISO),
Semantics, last paragraph, my emphasis added.
# There may also be unnamed padding at the end of a structure or union,
# as necessary to achieve the appropriate alignment *WERE* the structure
# or union to be an element of an array.
I may as well point out here the existence of comp.std.c, which is
specifically for topics about the C standard. If Dale had posted there,
he or she would no doubt have received half a dozen responses from people
familiar with the above text (followed, of course, by a minor flame war,
under the same Subject line, about some tangential topic or other...).
