In my MDK-ARM IDE, line 718 of ip6.c and line 121 of icmp6.c will cause the following warning:
\lwip-2.0.2\src\core\ipv6\icmp6.c(121): warning:  #111-D: statement is unreachable.

The icmp6.c is as follows, the break is unreachable after retrn:

I have checked latest 2.0.3, the issue is still there.
