 I wildly googled around and stumbled upon this:
 https://gitlab.gnome.org/GNOME/gtk/-/blob/main/gtk/gtkscale.c
 Curiously, the
 [https://gitlab.gnome.org/GNOME/gtk/-/commit/345d865ac6b2f7760503ab144dd68e6062438b80
 commit] that removed the `(GCompareFunc)` cast was 12 years ago. Line
 numbers are also totally different. I guess this is gtk3 source, and this
 change may not have been applied in gtk2.
