--- Comment #24 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
For the default, a complication is that standard C++ doesn't allow neither
flexible array members nor zero sized arrays, so unless one uses extensions one
can only write [1].
I think differentiating between only allowing [] as flex, or [] and [0],
or [], [0] and [1], or any trailing array is useful.
