I ran into this kind of problem myself. These virtual folders are a 
nuisance and it's bothersome and tricky to find out, especially as 
Sysnative is hidden by default.
But that's a Windows issue, not a cygwin issue. Cygwin doesn't handle 
other Windows paths either.

It doesn't add any other Windows folders so why this one. You should do 
that in your ~/.profile.
I'd suggest however to make those virtual folders visible from Cygwin, 
so you could find the hidden stuff from /Windows with ls, echo, or `find`.
