I'm not sure about arrays of structs, but glibc uses [0] at end of struct
in some cases where proper flexible array members would not be accepted.
E.g.
struct __gconv_info
{
size_t __nsteps;
struct __gconv_step *__steps;
__extension__ struct __gconv_step_data __data[0];
}
which is then used as a non-last member of another structure.
