      Rémi Bernon (@rbernon) commented about dlls/winmm/joystick.c:
...
+            if (is_already_mapped( object_formats, data_format.dwNumObjs, &instance ))
+                continue;

+            object_format = &object_formats[data_format.dwNumObjs++];
+            object_format->dwOfs = offsetof(struct joystick_state, axes[i]);
+            object_format->dwType = instance.dwType;

+
+    object_format = &object_formats[data_format.dwNumObjs++];
+    object_format->pguid = &GUID_POV;
+    object_format->dwOfs = offsetof(struct joystick_state, pov);
+    object_format->dwType = DIDFT_OPTIONAL | DIDFT_POV | DIDFT_ANYINSTANCE;
+
+    for (i = 0; i < 32; ++i)
    for (i = 0; i &lt; ARRAY_SIZE(((struct joystick_state *)0)->buttons); ++i)

(or a local joystick_state variable)
