;;; Synched up with: Not synched with FSF.  Almost completely divergent.

;;; Commentary:

;; This file is dumped with XEmacs for MS Windows (without cygwin).

;; Based on NT Emacs version by Geoff Voelker (voelker@cs.washington.edu)
;; Ported to XEmacs by Marc Paquette <marcpa@cam.org>
;; Largely modified by Kirill M. Katsnelson <kkm@kis.ru>

;;; Code:

;; The cmd.exe shell uses the "/c" switch instead of the "-c" switch
;; for executing its command line argument (from simple.el).
;; #### Oh if we had an alist of shells and their command switches.
(setq shell-command-switch "/c")

;; For appending suffixes to directories and files in shell
;; completions.  This screws up cygwin users so we leave it out for
;; now. Uncomment this if you only ever want to use cmd.

;(defun nt-shell-mode-hook ()
;  (setq comint-completion-addsuffix '("\\" . " ")
;	comint-process-echoes t))
;(add-hook 'shell-mode-hook 'nt-shell-mode-hook)

;; Use ";" instead of ":" as a path separator (from files.el).
(setq path-separator ";")

;; Set the null device (for compile.el).
;; #### There should be such a global thingy as null-device - kkm
(setq grep-null-device "NUL")

;; Set the grep regexp to match entries with drive letters.
(setq grep-regexp-alist
  '(("^\\(\\([a-zA-Z]:\\)?[^:( \t\n]+\\)[:( \t]+\\([0-9]+\\)[:) \t]" 1 3)))

;; Autosave hack
;;--------------------

;; Avoid creating auto-save file names containing invalid characters
;; (primarily "*", eg. for the *mail* buffer).
;; Avoid "doc lost for function" warning
