Hi, Vinay - Cygwin can use, and create, a variety of forms of links.  Some of these are understood 
by Windows tools, some not.  I suggest you read in the Cygwin documentation about symlinks and 
decide what kind are best for you.  Then you'll need to set that up, delete the existing link, and 
re-create it.  I personally run with CYGWIN=winsymlinks:native, but as we say in Internet land, YMMV.

Regards - Eliot Moss
