* emacs.c (__do_global_ctors, __do_global_ctors_aux,

	__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__, __main): Don't
	define these if ORDINARY_LINK is #defined; in that case, the
	standard linking procedure will find definitions for these.

	* emacs.c (main): SIGIOT isn't defined on all systems; don't set
	its signal handler unless it is.
