MarsSeed [1] filed a deletion request for mingw-w64-gtk3-bin [2]: Orphaned, last updated 2 years ago, binary source gone. Not needed, the build-from-source package can be used instead: https://aur.archlinux.org/packages/mingw-w64-gtk3 The above-linked package is maintained and kept up-to-date. Safe to delete this.
