enumInterfaces may return -1 for error conditions other than
IP Helper Library GetIfTable function failed. I wonder if this
specific failure should have its own separate return value,
maybe -2, so as to not be confused with other error conditions?

Similarly enumAddresses_win.

Of course all call sites of these functions will need to be
checked if this is done, but there are not that many.
