Array-fields in struct have an addtional _*_size_ field if they have a length.

struct Foo {
	public unowned string[] array;
	public int i;
}

translates to

typedef struct _Foo Foo;
struct _Foo {
	gchar** array;
	gint array_length1;
	gint _array_size_;
	gint i;
};

Now this _*_size_ field gets omitted when using a struct initializer like:

const string[] SARRAY = { "foo", "bar" };
const Foo FOO = { SARRAY, 23 };

translates to:

const gchar* SARRAY[2] = {"foo", "bar"};
const Foo FOO = {SARRAY, G_N_ELEMENTS (SARRAY), 23};

and should be:

const gchar* SARRAY[2] = {"foo", "bar"};
const Foo FOO = {SARRAY, G_N_ELEMENTS (SARRAY), G_N_ELEMENTS (SARRAY), 23};
