Modified files:
	guile-core/libguile: gc.c 

Log message:
	* gc.c: (scm_default_init_heap_size_*): defined to take cards into
	account, but keeping more or less the same values as previously.
	added some simple helper macros.
	(CLUSTER_SIZE_IN_BYTES, ALIGNMENT_SLACK): defined to take cards
	into account.
	(BVEC_*, scm_mark_space_t, current_mark_space, mark_space_ptr,
	current_mark_space_offset, mark_space_head, get_bvec,
	clear_mark_space): new functions and supporting variables, types
	and macros that implement mark space management.
	(scm_igc): clear the mark space (all of it) before beginning the
	mark phase.
	(scm_gc_mark): changed the tests for rogue cells, much simplified
	throughout (no different mark bit locations to worry about now).
	(scm_mark_locations): don't consider card header cells.
	(scm_cellp): ditto.
	(scm_gc_sweep): simplified.
	(init_heap_seg): changed to take cards into account.
