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

[Jeffrey Smith (＠whydoubt)]

That does sound like the right way forward, though based on my back-of-the-envelope calculations I think there are some additional tweaks that need to be made.  Try comparing a tiny positive value with a tiny negative value.  The simplest way to fix this is non-intuitive:

```diff
-    if (x < 0)
+    if (x >= 0)
         x = INT_MIN - x;
-    if (y < 0)
+    if (y >= 0)
         y = INT_MIN - y;
```

Adding a `compare_uint` everywhere we have a `compare_float` does not seem ideal (neither does all of the separate copies of `compare_float` already floating around). Would both of these functions be better off in some shared test header?
