Cygwin also uses euidaccess (or should, anyway):
http://cygwin.com/ml/cygwin/2011-12/msg00364.html

But yes, you can totally have full access to a directory or file on a
Windows box while all permission flags show that you don't (I guess that
is also possible on UN*X, although I've never tried).  You'll never know
until you actually try.

Achim.
