 # - Install files in right location
 # - configuration option to disable preprocessor build, and use it in {windows,macOS}/build.sh
 # - add -Wold-style-cast C++ flag except when building flex-generated files
+#   (only when warning_level ⩾ 2)
 # - add the possibility to customize the integration test names (with a new optional 'name' keyword in the dictionaries)
 # - Add an option to skip the removal of the temporary test directories, for debugging purposes
 # - See what to do with xvfb-run (see #1892). Maybe try to detect it from meson.build, and pass it optionally to the test driver script
