view lisp/blessmail.el @ 4843:715b15990d0a

add more foo_checking_assert macros lisp.h: Add structure_checking_assert(), gc_checking_assert(), etc. for all types of error-checking. Also FOO_checking_assert_with_message() and inline_FOO_checking_assert() -- the latter for use in an inline function where you want the calling function's line/file to be reported (requires some conspiracy with the function itself). Add disabled_assert(), disabled_assert_at_line(), disabled_assert_with_message(), for what to do when an assert is disabled. Formerly, we used to do ((void) 0), but now we do ((void) x), so the variable appears used and any side effects of the expression do get done. In Unicode-internal, the standard assert() uses this, but not yet in this workspace.

;;; Synched up with: FSF 19.34.

;;; Commentary:

;; This is loaded into a bare Emacs to create the blessmail script,
;; which (on systems that need it) is used during installation
;; to give appropriate permissions to movemail.
;;
;; It has to be done from lisp in order to be sure of getting the
;; correct value of rmail-spool-directory.

;;; Code:

;; These are no longer needed because we run this in emacs instead of temacs.
;; (message "Using load-path %s" load-path)
;; (load "paths.el")
;; It is not safe to load site-init.el here, because it might have things in it
;; that won't load properly unless all the rest of Emacs is loaded.
