declaring filler space in a struct

Is there a way to declare space in a struct as unused / filler / pad, in such as way as to not have to provide an identifier?

For example,

Code:

---

struct foo {
  int  .  ;      // just 4 bytes, padding for later, don't need it now
  int myval ;
} ;

---

You can have unnamed bit-fields.

Code:

---

#include<stdio.h>
#include<stdlib.h>
#include<stddef.h>

int main()
{
    struct foo {
        int : 32;
        int myval;
    } bar;
    bar.myval = 42;
    printf("%zd\n",offsetof(struct foo,myval));
    return 0;
}

---

Though 99% of people will just say this and think no more of it.

Code:

---

struct foo {
  int dummy;
  int myval;
};
