Hello,
I use cygwin and installed emacs-22.3.
The first several lines of my .emacs file is list bellow:

	(tool-bar-mode nil)
	(scroll-bar-mode nil)
	(set-background-color "black")
	(set-foreground-color "white")
	(set-cursor-color "green")
	(set-mouse-color "blue")
	(partial-completion-mode t)
	(server-start)

And error reported with "emacs --debug-init":
	Debugger entered--Lisp error: (error "The directory /tmp/emacs27953 is unsafe")
	  signal(error ("The directory /tmp/emacs27953 is unsafe"))
	  error("The directory %s is unsafe" "/tmp/emacs27953")
	  server-ensure-safe-dir("/tmp/emacs27953")
	  server-start()
