+Subject: [PATCH] meson: don't error on clang's -Wunused-but-set-global
+
+clang 23 added -Wunused-but-set-global to the -Wunused-but-set-variable
+group, so the -Werror=unused-but-set-variable in test_cflags now turns
+it into an error. It fires on the <type>_parent_class variables that
+GLib's G_DEFINE_TYPE family of macros emit, which pango cannot fix, and
+on a few deliberately write-only globals in the test suite.
+
+Keep the warning visible but not fatal. gcc does not know this warning
+group, so cc.get_supported_arguments() drops the flag there.
+
+Upstream-Status: Submitted [https://gitlab.gnome.org/GNOME/pango/-/issues/900]
