...isn't it?

from cygwin website (first page):

Cygwin is not:

-    a way to run native Linux apps on Windows. You must rebuild your 
application
      from source if you want it to run on Windows.
-    a way to magically make native Windows apps aware of UNIX® 
functionality like
      signals, ptys, etc. Again, you need to build your apps from source 
if you want
      to take advantage of Cygwin functionality.

Marco
