Trivially, I don't think getDefaultScopeID needs it's implementation to
be ifdef'ed with MACOSX, at all. Then won't need the 'else return 0;'.
It is just a general utility method to get the value of the defaultIndex
field of NetworkInterace. Yes, the value will be 0 on all platforms
other than Mac, but equally getDefaultScopeID will not be called on any
platform, other than Mac.
