in interval_mul and interval_div. This avoids an optimization bug
in A Certain Company's compiler (and given their explanation, I wouldn't
be surprised if other compilers blow it too). Besides the code seems
more clear this way --- in the original formulation, you had to mentally
recognize the common subexpression in order to understand what was going

IPv6 is obsoleted by recent Windows patch. Perform the runtime test
whenever HAVE_IPV6 is set. This should be OK since initdb can get
getaddrinfo from libpgport if needed.
