use the posix form, please.

see http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
  "Using native Win32 paths

  Using native Win32 paths in Cygwin, while possible, is generally 
inadvisable."

as example with a different program:

$ ls "E:/cygwin/tmp/sombrero_1_1.png"
cygwin warning:
   MS-DOS style path detected: E:/cygwin/tmp/sombrero_1_1.png
   Preferred POSIX equivalent is: /tmp/sombrero_1_1.png
   CYGWIN environment variable option "nodosfilewarning" turns off this 
warning.
   Consult the user's guide for more details about POSIX paths:
     http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
E:/cygwin/tmp/sombrero_1_1.png

$ ls "/cygdrive/e/cygwin/tmp/sombrero_1_1.png"
/cygdrive/e/cygwin/tmp/sombrero_1_1.png
