--- Comment #20 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
If I remove the
#include <linux/mroute6.h>
it still compiles just fine here on Fedora 19, looks like only the
linux/mroute.h
ioctls are instrumented.
Anyway, sounds to me like this badly needs autoconf and HAVE_LINUX_MROUTE6_H
etc.
for headers which aren't available everywhere.
