Why don't you fill in dummy members to get the correct alignment?
Like

        struct {
                unsigned char count;
                unsigned char dummy[7]; // for 8 byte alignment
                struct something_else_t array[];
        }

You'd lose that memory anyway if the compiler aligns it himself.
