I thought dynamic arrays were unavailable under -betterC.
Example_02:
```
extern(C) void main() {
import core.stdc.stdio : printf;
int[] A;
printf("Hello betterC\n");
}
```
```
dmd -betterC -run Example_02
```
Expected result: Failure at compilation stage, owing to presence
of dynamic array A, when -betterC set.
Actual result: Ran to completion, dislaying the message.
Example_03:
```
void main() {
import core.stdc.stdio : printf;
int[] A;
printf("Hello betterC\n");
}
```
```
dmd -betterC -run Example_03
```
Expected result: Failure at compilation stage, owing to presence
of dynamic array A, when -betterC set.
Actual result: Failed at link (not compilation) stage.
