I get "w32-native".

Yes, it does.

This will work. However, I tested on another C program and the problem
still occurs, meaning that my Emacs is buffering everything for some
reason.
Here is my test file:
```
#include <stdio.h>
#include <unistd.h>
int main() {
for (int i = 0; i < 5; ++i) {
printf("%d\n", i);
sleep(1);
}
return 0;
}
```
