Subject: * klist.c: Include k5-int.h and fake-addrinfo.h.
X-Git-Tag: krb5-1.3-alpha1~1145
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=1f81df2cc26446e1dca006573932ef6927c82915;p=krb5.git

* klist.c: Include k5-int.h and fake-addrinfo.h.
(NEED_SOCKETS, FAI_PREFIX, FAI_IMPLEMENTATION): Define macros.
(one_addr): Use getnameinfo always.
