dnl Most platforms that provide inet_ntop define it in libc.
dnl Solaris 8..10 provide inet_ntop in libnsl instead.
dnl Solaris 2.6..7 provide inet_ntop in libresolv instead.
+ dnl Haiku provides it in -lnetwork.
dnl Native Windows provides it in -lws2_32 instead, with a declaration in
dnl <ws2tcpip.h>, and it uses stdcall calling convention, not cdecl
dnl (hence we cannot use AC_CHECK_FUNCS, AC_SEARCH_LIBS to find it).
