I don't use shell scripts for this; I use Emacs functions:

(defun ghdl-0.25 ()
  "ghdl only; run from a DOS shell"
  (interactive)
  (setq exec-path
        (list
         (expand-file-name "~/bin")
         (getenv "INSTALL_BIN")
         "c:/Gnu/Emacs/emacs-21.3/bin"
         "c:/Gnu/Ghdl-0.25/bin"
         "c:/Windows/system32"))
  (setenv "PATH" (mapconcat 'identity  exec-path  path-separator))
  )
  
(defun sal-no-network ()
  "set LM_LICENSE_FILE to just the hardware key, to avoid network delays"
  (interactive)
  (setenv "LM_LICENSE_FILE" "foo")
  )
