Here’s an example where the warning is completely false. There are no missing
initialisers because I’ve listed them both.

struct {
    struct {
        int first;
        int second;
    } inner;
} outer = {
    .inner.first = 1,
    /* Warning -> */ .inner.second = 2,
};

With the -Wextra flag, GCC 4.7.0 produced:

bug.c:8:22: warning: missing initializer [-Wmissing-field-initializers]
bug.c:8:22: warning: (near initialization for ‘outer.inner.second’)
[-Wmissing-field-initializers]
