emacs-w3m sets the environment variable.  I just downloaded the source 
for the latter from http://emacs-w3m.namazu.org/ and found the setting 
of the CYGWIN variable in w3m.el.  Just edit that file and remove the 
setting.  Alternatively, it looks like you could solve the problem by 
customizing 'w3m-command-environment'.

This is not a Cygwin problem.  I suggest that you report this to the 
emacs-w3m mailing list.
