Subject: [PATCH] Fix `-Wundef` warning

Using GCC 11.4.0 with the `-Wundef` flag on Linux, I get the following warning:

```bash
warning: "_WIN32" is not defined, evaluates to 0 [-Wundef]
```

Since the codebase uses `#ifdef _WIN32` elsewhere, it seems like a proper fix
to change the two remaining instances of `#if _WIN32`.
