+
+This test serves two purposes:
+
+(1) It documents all existing warnings that currently have no associated -W flag,
+ and ensures that the list never grows.
+
+ If take an existing warning and add a flag, this test will fail. To
+ fix this test, simply remove that warning from the list below.
+
+(2) It prevents us adding new warnings to Clang that have no -W flag. All
+ new warnings should have -W flags.
+
+ If you add a new warning without a flag, this test will fail. To fix
+ this test, simply add a warning group to that warning.
+
+
+The list of warnings below should NEVER grow. It should gradually shrink to 0.
