Subject: Forward declaration of enum iterator_selection?
Message-ID: <933f540f-7752-cfce-5785-b67728fea987@kdbg.org>

When refs.c is being compiled, the only mention of enum 
iterator_selection is in this piece of code pulled in from 
refs-internal.h (have a look at the preprocessed code):

typedef enum iterator_selection ref_iterator_select_fn(
		struct ref_iterator *iter0, struct ref_iterator *iter1,
		void *cb_data);

This looks like a forward declarations of an enumeration type name, 
something that I thought is illegal in C. Am I wrong? (That may well be 
the case, my C-foo is quite rusty.)

My compiler does not complain (it's gcc 4.8), but I thought I mention it 
before someone with a pickier compiler stumbles over it...
