I don't have a WIndows box handy to test on, so Rob could you try this
patch? Visual Studio 2008 declares inet_ntop and inet_pton, but those
functions are only actually available on Windows Vista and later. This
patch allows testing for the declaration separately from the definition,
so we declare the functions only if necessary and then always compile
nbase's versions.

Another potential source of incompatibility is that Windows declares the
string parameters to the functions as PTSTR, which is a pointer to
either char or wchar_t. If the patch doesn't work, please try again
after adding the line

#undef UNICODE

above #include <ws2tcpip.h>
