No, it's not because there is only one element. You're allowed to
initialise all the elements of nested structs in storage layout order,
without putting in braces for all the sub-structs, e.g.:

struct {
        struct {
                int a, b;
        } c;
        struct {
                int d, e;
        } f;
} g = { 1, 2, 3, 4 };

See C99 6.7.8 "Initialization" paragraph 16 ff. for the rules (which I
find quite hard to read).
