[0] is a notation used for flexible array members, placed at the end of
a struct. It does not actually mean the array is of size 0. It seems
that [0] may have fallen out of use now in favor of [] which is how it
is defined in the C99 standard.
I have not tested this in any way whatsoever, but here is a quick
patch[1] that makes it compile again, that you could try. If you do try
it, let us know how it works.
