The preceding four statements are _executable_ statements (assignments)
and cannot appear by themselves in the global scope. You can make them
part of some bogus (dummy) initialisation. Otherwise, they have to be
part of a function.

AFAICT, the existence of executable statements in the global scope.
You'd get the same for this simple program:
int a[2];
a[0] = 42; // executable statement in global scope!
a[1] = 43; // same problem
int main() {
return 0;
}
