Hm, this is harder than you might think.  You should look in the email
archives for further discussion.  You realize, of course, that cygpath
can provide you information about mount points, right?  Invoking 
external processes like this to find the information you want is probably 
an easier way to get at some limited functionality.  But don't let me stop
you from playing around with linking directly! ;-)
