With CLang we're getting failures from cats in GLib macros ../dist-unpack/libvirt-6.10.0/src/util/vireventthread.c:35:1: error: passing 'typeof (*(&g_define_type_id__volatile)) *' (aka 'volatile unsigned long *') to parameter of type 'gsize *' (aka 'unsigned long *') discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers] G_DEFINE_TYPE(virEventThread, vir_event_thread, G_TYPE_OBJECT) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The cast is valid and there's no way for libvirt to workaround the issue, so we must disable this CLang warning flag.
