           Summary: const struct initialized with struct literal recreates
                    value on stack when used

As the following code shows the const S s isn't really initialized with a
constant that's put into the data segment, but works more like "alias S(5) s;".

---
struct S { int i; }

const S s = S(5);
const S u = { 5 };

void foo(int num) {
  printf("%p %p\n", &s, &u);
  if (num > 0)
    foo(num-1);
}

void main() {
  foo(2);
}

output:
0xbfc1774c 0x80601a0
0xbfc17738 0x80601a0
0xbfc17724 0x80601a0
