That's because you build all files that are present on disk. You have to 
exclude the ones you don't want (IPv6) instead of autimatically building 
everything that's there.

That info is not valid for versions <= 1.4.x. Before the redesign, the IPv6 
implementation could not be used at the same time as IPv4, that's why you get 
compiler errors.

As stated above, it *might* be compilable instead of IPv4. However, I doubt 
anyone has used it in the past...
