Usually my approach is (in the headers) just to declare the structure like

struct Dummy;

and use the full name like

void do_something(struct Dummy *dummy);

we had a similar discussion with Marc-Andre and one option would be to move
all struct typedefs' in red-common.h (which is included in all files).
I think would be worth but could be quite some manual work.
Also I think this is not the style GObject is using.
