Argh, current trunk is broken with !GC_MARK_STACK anyway:

1) I don't know why this isn't in the trunk:
   http://lists.gnu.org/archive/html/emacs-devel/2011-11/txtjY_VzSBijo.txt

2) My stuff from commit 111073 breaks !GC_MARK_STACK because Lisp_Objects
   referenced from Lisp_Misc_Save_Value are marked only if GC_MARK_STACK :-(.
