Re: [PATCH v3 0/1] MR3458: ddraw/tests: Fix overflow bugs in compare_float.

[Jeffrey Smith (＠whydoubt)]

It might be a good idea to make it so that zero compared with non-zero is consistently unequal (rather than erratically as with only the `compare_uint` change).  Doing so could look like this:

```diff
-    if (x < 0)
-        x = INT_MIN - x;
-    if (y < 0)
-        y = INT_MIN - y;
+    if (x == INT_MIN)
+        x = 0;
+    if (y == INT_MIN)
+        y = 0;
+    if (x == 0 || y == 0)
+        return x == 0 && y == 0;
```
