dnl CURL_CHECK_FUNC_GETNAMEINFO
dnl -------------------------------------------------
dnl Test if the getnameinfo function is available,
dnl and check the types of five of its arguments.
dnl If the function succeeds HAVE_GETNAMEINFO will be
dnl defined, defining the types of the arguments in
dnl GETNAMEINFO_TYPE_ARG1, GETNAMEINFO_TYPE_ARG2,
dnl GETNAMEINFO_TYPE_ARG46 and GETNAMEINFO_TYPE_ARG7,
dnl and also defining the type qualifier of first
dnl argument in GETNAMEINFO_QUAL_ARG1.
