MarsSeed [1] filed a deletion request for xfwm4-gtk2 [2]: Obsolete EOL Gtk2 based Xfce4 app. Upstream uses Gtk3 now. Latest version is available in [extra] repo. Many Gtk2 Xfce4 apps fail to build on current Arch Linux. This one also neglects to declare all its needed, direct dependencies. See deletion request PRQ#52678 [a] for additional context and rationale.
