+Subject: [PATCH] Always define the raii_event_tests test suite
+
+The test suite must always be defined (even when EVENT_SET_MEM_FUNCTIONS_IMPLEMENTED is not defined) so that the test harness doesn't fail due to not being able to find the raii_event_tests test.
+
+This improves upon 95f97f4 actually fixing https://github.com/bitcoin/bitcoin/issues/9493
