Richard says

<<No, the size of T would be 16 bytes.  It would be rounded up to a multiple
of its alignment, precisely to avoid problems with an array of them.

Richard is talking about the behavior of gcc, which I know well (this
requirement that the size be a multiple of the alignment is an annoying
limitation for Ada, that causes incompatibilities with previous Ada
compilers).

But that's not the question. The question is whether the ANSI C standard
requires this behavor. I must say I have trouble reading the standard,
I don't know it that well, so the fact that I can't prove it is not at
all decisive, but so far no one else has provided the proof either.
