[lwip-users] Can IPv4 co-exist with IPv6?

[Epyon]

I'am using lwIP version 1.3.2 and I want to have support for IPv4 as well as
IPv6.

However when building the lwIP stack I get the following link errors, 
indicating that it is not possible to have both IP versions run
simultaneously?

Can anyone help me with this problem?
