I guess I don't have a strong opinion here, since these helpers are specific to
C++, and I've been generally trying to remove fixed-size 0-sized arrays in C
projects (i.e. the Linux kernel). I do care about C flexible arrays (and their
associated extensions), though. I suspect there is some existing weirdness for
C++ when using static initializers, though. See https://godbolt.org/z/PnYMcxhfM
```
struct S { int a; int b[]; };
static struct S s = { .a = 42, .b = { 10, 20, 30, 40 }, };
static struct S z = { .a = 13, };
```
Specifically `z.b` is a 0-sized flexible array, but `s.b` isn't. Should they
have different results?
