No, if I do that I have to explicitely start

/usr/bin/vim.gtk -u /etc/vim/vimrc -N Makefile.am

then it reproduces (after a :syntax on).
If I do:

vim -u /etc/vim/vimrc -N Makefile.am

then it doesn't reproduce.

PS 

'vim' is a personalized script here ;)

      FILE=`echo "$FILE" | sed -e 's%^\.\./%%'`
    done
  fi
done

eval /usr/bin/vim $ARGS


Running "/usr/bin/vim -u /etc/vim/vimrc -N Makefile.am" also reproduces.
