I'm not arguing that. I'm simply stating that if the GNULIB module is
going to *ignore* these POSIX specified flags, as you said your app
does, then the reasons for this and any potential dangers involved in
doing so should be well-documented.

I understand that. I was simply stating that, while I believe a more
complete implementation of getaddrinfo would be wonderful, many
applications get along just fine with the current, incomplete
implementation. I just wanted to be sure that the phrasing of Bruno's
statement about GNULIB modules being complete "if possible" didn't imply
that incomplete modules should be removed when so many apps get along
without the missing functionality.
If the getaddrinfo module doesn't get completed, documentation of the
missing functionality would probably be nice so that no one else is so
surprised when getaddrinfo fails. I came up with the attached patch,
but perhaps a shorter note in the modules file like, "* Incomplete - see
lib/getaddrinfo.c." would be better. The extra notes my patch adds to
modules/getaddrinfo could then be added to lib/getaddrinfo.c, then, but
I think they would be superfluous.
