Subject: * aclocal.m4 (KRB5_AC_INET6): Look for netdb.h.
X-Git-Tag: krb5-1.3-alpha1~1748
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=a2998a8aaef79e7fa85da7e07fef7462381bcf34;p=krb5.git

* aclocal.m4 (KRB5_AC_INET6): Look for netdb.h.
(KRB5_AC_CHECK_INET6): Require <netinet/in.h>, <netdb.h>, inet_ntop,
getaddrinfo, AF_INET6, several NI_* macros, AI_ADDRCONFIG, and AI_NUMERICHOST.
This should be a reasonable test for conformance to certain parts of RFC2553,
giving us reasonable generic sockaddr/hostname processing.
