+
+       this changes the Guile GC to use cards (aka "chunklets").
+
+       * tags.h: (SCM_GCTYPE16, SCM_GCCDR, SCM_GC[8]MARKP,
+       SCM_SETGC[8]MARK, SCM_CLRGC[8]MARK): moved from here into gc.h.
+       some (most) of these are probably going to be deprecated.
+
+       * gc.h (SCM_MARKEDP): simplified, there are no different mark bit
+       locations anymore.
+       (SCM_GC_CARD_*, SCM_C_BVEC_*): lots of new macros to deal with
+       cards and bvecs (bit-vectors).
+
+       * 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.

        * stime.c (scm_c_get_internal_run_time): new function, same as
