   Some LISP-visible command-line options are set by SXEmacs _before_ the

   values SXEmacs is getting at runtime.  Such variables must be saved
   before loading the dumpfile, and restored afterward.

   Therefore these variables may not be initialized in vars_of_emacs().

   The save/restore is done immediately before and after pdump_load() in
   main_1().  See that function for the current list of protected variables.

   Note that saving/restoring is only necessary for a few variables that are
     o command line arguments effective at runtime (as opposed to dump-time),
     o parsed before pdump_load, and
     o exported to Lisp via a DEFVAR.

/* Ben's capsule summary about expected and unexpected exits from SXEmacs.

   Expected exits occur when the user directs SXEmacs to exit, for example
   by pressing the close button on the only frame in SXEmacs, or by typing
   C-x C-c.  This runs `save-buffers-kill-emacs', which saves any necessary
   buffers, and then exits using the primitive `kill-emacs'.

   However, unexpected exits occur in a few different ways:

     -- a memory access violation or other hardware-generated exception
        occurs.  This is the worst possible problem to deal with, because
        the fault can occur while SXEmacs is in any state whatsoever, even
        quite unstable ones.  As a result, we need to be *extremely* careful
        what we do.
     -- we are using one X display (or if we've used more, we've closed the
        others already), and some hardware or other problem happens and
        suddenly we've lost our connection to the display.  In this situation,
        things are not so dire as in the last one; our code itself isn't
        trashed, so we can continue execution as normal, after having set
        things up so that we can exit at the appropriate time.  Our exit
        still needs to be of the emergency nature; we have no displays, so
        any attempts to use them will fail.  We simply want to auto-save
        (the single most important thing to do during shut-down), do minimal
        cleanup of stuff that has an independent existence outside of SXEmacs,
        and exit.

        Currently, both unexpected exit scenarios described above set
        preparing_for_armageddon to indicate that nonessential and possibly
        dangerous things should not be done, specifically:

        -- no garbage collection.
        -- no hooks are run.
        -- no messages of any sort from autosaving.
        -- autosaving tries harder, ignoring certain failures.
        -- existing frames are not deleted.

        (Also, all places that set preparing_for_armageddon also
        set dont_check_for_quit.  This happens separately because it's
        also necessary to set other variables to make absolutely sure
        no quitting happens.)

        In the first scenario above (the access violation), we also set
        fatal_error_in_progress.  This causes more things to not happen:

        -- assertion failures do not abort.
        -- printing code does not do code conversion or gettext when
           printing to stdout/stderr.
*/

/* Non-nil means we're going down, so we better not run any hooks

           temacs w/ run-temacs on the command line -- This is run to bytecompile
           all the out of date dumped lisp.  It will execute both of the main_1
           calls and the second one must not touch the first computation because
           argc/argv are hosed the second time through.

           sxemacs -- Only the second main_1 is executed.  The invocation path must
           computed but this only matters when running in place or when running
