Well, I think that's not really necessary. Just use gerror->messsage.
You could do it and allow it to be NULL, but I don't think it buys you

Right, so the v-functions are just implementation details, not part of
the exported API. That's better.

How would the x and non-x versions be used then (/me is ignorant,

hmm, there was some talk about this earlier, where people said they
preferred dynamic memory allocation. I am not qualified to comment on
this, though.
