        * allchblk.c (GC_print_hblkfreelist, GC_dump_regions): Convert
        a group of printf() calls into a single one (for output atomicity).
        * include/gc.h (GC_set_all_interior_pointers, GC_set_full_freq,
        GC_set_time_limit): New prototypes.
        * misc.c (GC_set_all_interior_pointers, GC_set_full_freq,
        GC_set_time_limit): New public setter/getter functions.
        * include/gc.h: Fix (and remove outdated) comments for thread-local
        allocation.
        * include/gc.h: Fix typos in comments.
        * misc.c (GC_init_inner, GC_printf): Ditto.
        * include/gc.h (GC_unregister_disappearing_link): Refine comment.
        * include/gc.h (GC_stack_base): Recognize _M_IA64 macro.
        * misc.c (GC_stack_last_cleared, GC_min_sp, GC_high_water,
        GC_bytes_allocd_at_reset, DEGRADE_RATE): Define only if THREADS.
        * misc.c (GC_stack_last_cleared, GC_min_sp, GC_high_water,
        GC_bytes_allocd_at_reset): Define as STATIC.
        * misc.c (GC_get_heap_size, GC_get_free_bytes,
        GC_get_bytes_since_gc, GC_get_total_bytes): Acquire the GC lock to
        avoid data races.
        * misc.c (GC_write_cs): Define only if THREADS (Win32/WinCE only).
        * misc.c (GC_init_inner): Initialize GC_write_cs only if THREADS.
        * misc.c (GC_init_inner): Use GC_INITIAL_HEAP_SIZE (if available) to
        set the default initial value of initial_heap_sz.
        * misc.c (GC_deinit): Destroy GC_write_cs only if THREADS.
        * misc.c (GC_init_inner): Fix WARN() format specifier (should be
        word-complient, "%p" is used w/o "0x").
        * misc.c (GC_init_inner): Don't recognize "GC_PAUSE_TIME_TARGET"
        environment variable if SMALL_CONFIG.
        * misc.c (GC_init_inner): Recognize "GC_FULL_FREQUENCY" environment
        variable to set initial GC_full_freq value (if not SMALL_CONFIG).
        * doc/README.environment (GC_FULL_FREQUENCY): Add information.
        * doc/README.environment (GC_MARKERS): Refine information.
        * misc.c (GC_init_inner): Change GC_ASSERT to GC_STATIC_ASSERT where
        possible.
        * misc.c (IF_NEED_TO_LOCK): New macro (instead of GC_need_to_lock).
        * misc.c (GC_write): Use IF_NEED_TO_LOCK for handling GC_write_cs.
        * misc.c (GC_abort): Don't define if SMALL_CONFIG.
        * misc.c (GC_abort): Directly use WRITE() instead of GC_err_printf()
        (to prevent possible infinite recursion).
