Although in this case, devuan ascii's /usr/include/linux/if_tunnel.h #includes
linux/ip.h. Let's see, in current kernel sources...
$ git annotate include/uapi/linux/if_tunnel.h | grep ip.h

<linux/ip.h>

include/uapi/linux/if_tunnel.h: include linux/if.h, linux/ip.h and
linux/in6.h
Fixes userspace compilation errors like:
error: field ‘iph’ has incomplete type
error: field ‘prefix’ has incomplete type

So this is a bug that was fixed in upstream kernel sources 4 years ago
(v4.8-rc3), and the 5.4 kernel was released November 24, 2019.
Are you sure you're using 5.4 kernel headers?
