On the contrary, you might also want to get deprecation warnings for symbolsdeprecated in newer versions, typically when preparing a dependency bump ortrying to improve forward compatibility.To do so, use the -UGLIB_VERSION_MIN_REQUIRED flag for GLib deprecations,and -UGDK_DISABLE_DEPRECATION_WARNINGS for GTK and GDK ones.To change the lower deprecation bound for GLib (and then get warnings aboutsymbols deprecated more recently) instead of simply removing it entirely, use-UGLIB_VERSION_MIN_REQUIRED -DGLIB_VERSION_MIN_REQUIRED=GLIB_VERSION_X_YY.
