I see nothing about passing by value different from structure assignment,
which ignores the flexible array member (see 6.7.2.1 paragraph 22 (in
N1256) for an example stating this). Although argument passing and return
aren't strictly assignments, they generally act in the same way, so such a
structure passed by value or used as a function return value loses the
flexible array members in the process. I suppose an optional warning for
this might be useful.
