Hmm, so gnulib is a library (never heard of it before). I downloaded it
and looked at all the Local Variables section in all the files. Some of
the variables used were not marked as safe in Emacs, this was causing
warnings. I marked them as safe on the emacs-22.2 CVS branch. It will
get merged into CVS HEAD soon.

The only issue left with the local variables in gnulib is: 
# eval: (add-hook 'write-file-hooks 'time-stamp)

This cannot be marked as safe as it is.
Does anyone know if we already have a solution for something that
updates the time stamps when saving?
If not, do we want to add such a solution?
What would that solution be?
