-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.
