CONFIG_NF_NAT_MASQUERADE_IPV6=m
 # CONFIG_IP6_NF_TARGET_MASQUERADE is not set

results in:

net/ipv6/netfilter/nf_nat_masquerade_ipv6.c: In function ‘nf_nat_masquerade_ipv6’:
net/ipv6/netfilter/nf_nat_masquerade_ipv6.c:41:14: error: ‘struct nf_conn_nat’ has no member named ‘masq_index’

 }
 ^
make[3]: *** [net/ipv6/netfilter/nf_nat_masquerade_ipv6.o] Error 1

Fix this by using the new NF_NAT_MASQUERADE_IPV4 and _IPV6 symbols
in include/net/netfilter/nf_nat.h.
