Nothing in Cygwin packages should install anything under /etc/default/.

Under Cygwin /etc/defaults/ - note plural - contain originals of package system 
config files to be installed under /etc/..., /usr/share/.../, or
/var/{games,lib}/.../ by package postinstall scripts if not already present, and 
removed on package upgrades by preremove scripts if not modified by the admin 
since install, determined by comparison with the original under /etc/defaults/, 
otherwise the locally modified config file is retained.

This includes the user home directory setup files:

	$ la /etc/defaults/etc/skel/
	.bash_profile  .bashrc  .inputrc  .mkshrc  .profile

Some entries under /etc/ are symlinks:

$ find /etc/ -maxdepth 1 -type l | xargs -r ls -glo
