Re: getaddrinfo: test failure on Solaris 9

[Paul Eggert]

Further testing revealed that my previous fix wasn't right; sometimes
it works on Solaris, sometimes it doesn't, it's not worth our time to
figure out why.  So I installed the following fix instead: it causes
the test to ignore all failures of the kind observed on Solaris.

It does seem to me that the test is a bit dicey for other reasons,
e.g., suppose it's run on an isolated network that can't see
microsoft.com?

        Port test-getaddrinfo to Solaris.
        Problem reported by Bruno Haible in
        <http://lists.gnu.org/archive/html/bug-gnulib/2007-03/msg00171.html>.
        * tests/test-getaddrinfo.c (simple): Add a comment asking for an
        explanation of setting 'hints'.
        Don't reject an implementation merely because it returns EAI_SERVICE.
        (EAI_SERVICE): Define to 0 if not defined.
