Sorry, this turned out to be bogus; AI_ADDRCONFIG flag was already present as
early as FreeBSD 4.3-RELEASE, but I forgot adding the flag in my test code.
The flag is not documented in the getaddrinfo(3) man page.

I doubt RedHat 6 or MacOS X really support AI_ADDRCONFIG. Is it actually
defined somewhere in the system headers? Anyway it seems like its absence
is hidden by the following lines:

src/include/libpq/pqcomm.h:
85-/* Some systems don't have it, so default it to 0 so it doesn't
86- * have any effect on those systems. */
87:#ifndef      AI_ADDRCONFIG
88:#define      AI_ADDRCONFIG 0
89-#endif
