VIM in GNU coding style

I guess I'll start working on GCC recently, so I tried to prepare my VIM for GNU coding style. However, it's not as easy as I hoped, since VIM seems to favor BSD style more than GNU style which is a great waste of screen space in my view...Anyway, after a vast amount of Googling and attempts, it works now. Here's what I did to VIM: create a file named c.vim in my "~/.vim/after/ftplugin" directory, with the following content:

"GNU Coding Standards
setlocal cindent
setlocal cinoptions=>4,n-2,{2,^-2,:2,=2,g0,h2,p5,t0,+2,(0,u0,w1,m1
setlocal expandtab
setlocal shiftwidth=2
setlocal tabstop=8
setlocal softtabstop=2
setlocal textwidth=80
setlocal fo-=ro fo+=cql

I have to put it here otherwise the settings might be overrode by VIM's default ftplugin settings.
