See if you can use __builtin_choose_expr() instead. Look at include/osdep/atomic.h which defines typeof_strip_qual() without _Generic. linux-user/qemu.h __put_user_e() is also an example of what appears to be a poor-man's replacement to _Generic. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
