I had to make two changes to get this to work.  first I did this 
in build_bootp_record:

#define DONT_FORGET_TO_ADD_GATEWAY 1
#if DONT_FORGET_TO_ADD_GATEWAY
    addr = inet_addr(addrs_gateway);
    vp = add_tag(vp, TAG_GATEWAY, &addr, sizeof(in_addr_t));
#endif

This still didn't work.  It told me (addressed redacted):

Route - dst: 192.168.0.0, mask: 255.255.255.0, gateway: 192.168.0.92

which is the wrong mask for a default gateway.  So I added this in the
obvious place in bootp_support.c:

#define SET_GATEWAY_ROUTE_MASK_TO_ZERO 1
#if SET_GATEWAY_ROUTE_MASK_TO_ZERO
        memset(&route.rt_genmask, 0, sizeof(route.rt_genmask));
#else
        addrp->sin_addr = netmask;
        memcpy(&route.rt_genmask, addrp, sizeof(*addrp));
#endif

And now I can establish connections with the rest of the world.
This may well not be the best way to do this.
