imclient broken on Solaris 9

[Stephen Grier]

Dear all,

We've got Cyrus-imapd-2.2.10 running on on a Solaris 9 box, and
everything is fine, except for the cyradm utility, which fails with:

cyradm --user admin imap-test
imclient_connect: unknown host "imap-test" at /usr/local/lib/perl5/site_perl/5.8.5/sun4-solaris/Cyrus/IMAP/Admin.pm line 71.

Having done some debugging, the problem appears to be the getaddrinfo()
call of the imclient_connect() function of lib/imclient.c. It does not
appear to like the AI_CANONNAME flag as defined in netdb.h, and returns
EAI_BADFLAGS "invalid ai_flags". If I change line 238 to:

    hints.ai_flags = 2;

(which is how AI_CANONNAME is defined in lib/gai.h) cyradm works as
expected.

So the getaddrinfo() call in imclient_connect seems to expect
AI_CANONNAME to be as defined in lib/gai.h rather than as defined in
netdb.h. And this only seems to happen on Solaris 9, not Solaris 7/8.

Does anyone know why this is happening? I have found a couple of
references on this issue in the info-cyrus archives, but nothing
conclusive. We can work with the above fix for now, but I'd rather know
exactly what's going on here.

Regards,
Stephen
