I have looked into this problem. The cause is as follows.
netioapi.h in w32api-headers 3.3.0-2 was using a macro-name
_INC_NETIOAPI for include-guard. By defining _INC_NETIOAPI,
net.cc avoids including netioapi.h, which conflicts with
if_nametoindex() and if_indextoname() in it.
However, the macro-name for include-guard in netioapi.h of
w32api-headers 4.0.2-1 has been changed to _NETIOAPI_H_.
As a result, net.cc fails to avoid including netioapi.h,
which causes confliction.
Thus, defining _NETIOAPI_H_ in net.cc resolves the problem.
