Clang 16 makes casting function pointers between incompatible types an error, which causes Vala to fail to build things using glib-2.0.vapi. `-Wno-incompatible-function-pointer-types` is set unconditionally because it is supported by all versions of clang and GCC in nixpkgs. See https://gitlab.gnome.org/GNOME/vala/-/issues/1413.
