This happens now and then because most committers have INET6 enabled and
they forget that INET6 is an option and not mandatory.

I don't have INET6 enabled and have reported a number of problems in the
source as a result of that.

In general it's pretty simple to fix these problems by merely adding
#ifdef INET6 ... #endif to the code.
