That would imply that there are two distinct trees.  But, as I
understand it, / is a subtree of //.  If so, isn't // the "real" root,
and can't the algorithm simply use the dev and ino for // on Cygwin,
so that getcwd always returns a name that begins with "//"?  This
wouldn't remove the need for some //-specific stuff, but it would mean
fewer changes to the code.
