Right, I was just commenting on the mere existence of such function and 
its use to disable certain features, which in my mind seems kludgy for 
an OS that has been abandoned by its manufacturer, i.e. no more updates, 
bugfixes etc. But, I think your explanations in response to Oscars email 
made the intent of this clearer for me, i.e. what the status of support 
for legacy systems like Win9x is.

I just googled the UNC issue with Windows' stat and found that it 
actually supports UNC paths (in recent implementations at least), but 
there might be some other issues that I don't know about. Anyway, those 
were examples where comments led me to believe that there might be a 
cleaner solution for this nowadays, compared to what was available 15 
years ago or when the code was initially written.

Yes, I will dig around some more and see what I come up with. Which 
should help me get familiar with the code.

Thank you.
