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 Native Windows provides it in -lws2_32 instead, with a declaration in

dnl <ws2tcpip.h>, and it uses stdcall calling convention, not cdecl
