No; Standard C does not support zero-sized objects.

I'm POC for a zero-sized object special interest group,
but frankly there has been little activity since the
committee's consensus was clearly against such objects.

You might consider changing the [0]s to [1]s and where
the allocation/pointer trickery occurs in the code
making an adjustment for the additional byte in the
object type.
