+ More tests on warnings/strictness precedence.
+ * tests/warning-groups-win-over-strictness.test: New test, similar
+ to `warnings-win-over-strictness.test', but checking the explicit
+ catch-all warning flags (like `-Wall' and `-Wnone').
+ * tests/Makefile.am (TESTS): Update.
+
Update NEWS about the warnings-over-strictness precedence.
* NEWS: Automake explicit warning levels always take precedence
over the implicit warning levels implied by Automake strictness.
