Executing
 $ vim --version
shows
 system vimrc file: "$VIM/vimrc"
 user vimrc file: "$HOME/.vimrc"
 2nd user vimrc file: "~/.vim/vimrc"
 user exrc file: "$HOME/.exrc"
 fall-back for $VIM: "/etc"
 f-b for $VIMRUNTIME: "/usr/share/vim/vim74"
>From within vim,

 :echo $VIM
shows
 /usr/share/vim
To find out more about the value of $VIM, execute
 :help $VIM
So, Cygwin's vim looks for the system vimrc at /usr/share/vim/vimrc,
not /etc/vimrc. If you create that file, start vim and execute
 :scriptnames
you will see
 1: /usr/share/vim/vimrc
at the top of the list.
Personally, I really like that Cygwin does not include a system
vimrc in its vim package. If it did, I'd have to undo all those
settings or rm the file. I have a ~/.vimrc that works on Windows,
Cygwin, Ubuntu and Fedora and ensures that vim behaves the same on
all platforms. I don't want somebody else making those
configuration decisions for me.

I don't understand what you mean that the 5th line doesn't work and
has to be commented. I have "syntax on" in my ~/.vimrc file and
syntax highlighting works just fine. I have "set background=light"
in my colorscheme file and it works fine as well. Further, I can
execute ":set background=dark" and ":set background=light" from the
vim command line and see the color differences.
It sounds like some part of your installation is broken.
I'm using Cygwin's vim 7.4.663-1.
