than it otherwise would.

Test case 153 uses this in case you need an example. It is pretty involved
and hard-to-use, but then the situation is pretty special over all. Enjoy.

we use the NIFLAGS properly on both places in the code that use getnameinfo().

works. No code actually uses the HAVE_NI_WITHSCOPEID (that a positive test
results in), but this is still only for testing purposes.
