Why doesn't my Emacs regex with ^ match the line start?

I am trying to configure .emacsso that any file starting with letters makefilesets it to makefile mode. For instance. makefile-somethingmust be in makefile mode.

This does not work:

(setq auto-mode-alist (cons '("^makefile" . makefile-mode) auto-mode-alist))

But it does:

(setq auto-mode-alist (cons '("makefile" . makefile-mode) auto-mode-alist))

Can someone explain why?

This is because there is a path component in front of the file name, try:

"/makefile[^/]*$"

see http://www.gnu.org/s/emacs/manual/html_node/elisp/Auto-Major-Mode.html (bottom of page)
