Some build failures here:

gcc -D_GNU_SOURCE -O2 -Wstrict-prototypes -Wall -I../include -DRESOLVE_HOSTNAMES -DLIBDIR=\"/usr/lib/\"   -c -o link_gre.o link_gre.c
In file included from link_gre.c:15:
../include/linux/if_tunnel.h:33: error: field ‘iph’ has incomplete type
link_gre.c: In function ‘gre_parse_opt’:
link_gre.c:136: warning: implicit declaration of function ‘__constant_htons’

I seem to remember messing with the kernel headers in this
area recently... yes, indeed:

    net: Fix userland breakage wrt. linux/if_tunnel.h
    
    Reported by Andrew Walrond <andrew@...rond.org>
    
    Changeset c19e654ddbe3831252f61e76a74d661e1a755530
    ("gre: Add netlink interface") added an include
    of linux/ip.h to linux/if_tunnel.h
    
    We can't really let that get exposed to userspace
    because this conflicts with types defined in netinet/ip.h
    which userland is almost certainly going to have included
    either explicitly or implicitly.
    
    So guard this include with a __KERNEL__ ifdef.
