Building an independent package with cygwin:
--------------------------------------------
You can build automatically a zip file to install
on window and this zip file  doesn't need cygwin to be 
preinstalled.
But if cygwin has been allredy installed the ec application 
in the  ec zip file would not work similtaneously with another 
cygwin application.

To build the zip file after decompressing the tarball and with
cygwin :

./configure && make 
cd cygwin && make cygpkg
