This bug is about structures that are exposed in the public header. So they may
be taken as argument, or returned, by void* or parent* pointers, but it would
be nice to annotate the actual type

Ok, but I am looking for a more friendly way to express that *all* my types in
my headers must be taken into account without having to define such extra
symbols. Imho it should be an option to the tool somehow.
