* libguile/i18n.c (str_upcase, str_downcase, scm_char_locale_downcase,
  scm_char_locale_upcase): Cast chars to `int' when invoking `toupper ()'
  et al. to avoid "array subscript has type 'char'" on NetBSD.

69f23174d3 Use Gnulib's `strftime' to address bug #24130.

  bug #24130.

40945e5e9f Add a statistic for tracking how many cells are marked conservatively. 
This allows an informed choice for deciding how many segments to
create.  After startup, ~2% of the cells are scanned conservatively.

82ae1b8eb3 Garbage collection cleanup. 
* New file gc-segment-table.c: hold code for the segment table.

* Remove data that might be out of date; remove
  scm_i_adjust_min_yield().  We don't store min_yields, since they
  are only accurate at one point in time (when the sweep finishes). 
  We decide the min yield at that point from min_yield_fraction and
  freelist->collected / freelist->swept

* Introduce scm_i_gc_heap_size_delta() replacing
  scm_i_gc_grow_heap_p().
  
* Remove foo_1 fields containing penultimate results.

* After GC, count mark bit vector to discover number of live
  objects. This simplifies hairy updates.

* Many formatting and layout cleanups.

* Fix in scm_i_sweep_card(): return the length of free_list returned,
  rather than number of deleted objects.

* For mtrigger GCs: do not also run a full sweep after the gc() call, as
  this is inconsistent with lazy sweeping.

* Remove scm_i_make_initial_segment().

* Use calloc in scm_i_make_empty_heap_segment() to save on
  initialization code.

* New function scm_i_sweep_for_freelist() which sweeps, with proper
  statistic variable updates.

* New segments are conceptually blocks with 100% reclaimable cells.

* Remove some useless constants/comments: SCM_HEAP_SIZE,
  SCM_INIT_HEAP_SIZE, SCM_EXPHEAP, SCM_HEAP_SEG_SIZE

* Do not increment scm_cells_allocated() from the
  scm_[double]cell(). This would be a race condition.

* Move some deprecation checks in separate functions to not distract
  from main code flow.
