build error on IFNAMSIZ TUNInterface_linux.c due to compile option

git checkout and building currently fails on my end:

Arch Linux
Debian Stretch/sid

fails with:

Error: gcc -c -x cpp-output -o build_linux/interface_tuntap_TUNInterface_linux_c.o -std=c99 -Wall -Wextra -Werror -Wno-pointer-sign -pedantic -D linux=1 -D CJD_PACKAGE_VERSION="cjdns-0.3-3823-g7f5caec" -Wno-unused-parameter -D Log_DEBUG -g -D NumberCompress_TYPE=v3x5x8 -D Identity_CHECK=1 -D Allocator_USE_CANARIES=1 -D PARANOIA=1 -DHAS_ETH_INTERFACE=1 -fPIE -fno-stack-protector -fstack-protector-all -Wstack-protector -O3 build_linux/interface_tuntap_TUNInterface_linux_c.o.i

test program w. gcc 6 (on sid with gcc 5+6 too):


#include <stdio.h>
#include <net/if.h>
#include <linux/if.h>

int main(void) {
        printf("IFNAMSIZ: %d",IFNAMSIZ);
        return 0;
}

std=c99 fails
std=gnu99 succeeds
