	gcc            : ChangeLog ggc-zone.c 

Log message:
	* ggc-zone.c (struct alloc_zone): Don't pre-declare, it already
	comes in with ggc.h.  Add a new bool field `dead'.
	(destroy_ggc_zone): Don't destroy a zone at once.  Instead, only
	set the `dead' flag for the dead zone.  Wrap a sanity check in
	ENABLE_CHECKING.
	(ggc_collect_1): Always mark and sweep if a zone has the `dead'
	flag set.
	(ggc_collect): Free dead zones after collecting.
