That's not what the draft said last time I looked at it. Rather, it said
that a pointer to void can be converted to this type and then back to a
pointer to void, which is the opposite of what I said above.

Even if the draft has changed, it doesn't help with the "typedef int gint"
problem. And of course, a draft is a draft and does not (yet) define what
C is.
