        * dbg_mlc.c (GC_print_smashed_obj): Convert a group of printf()
        calls into a single one (for output atomicity).
        * typd_mlc.c (GC_calloc_explicitly_typed): Don't declare and use
        GC_finalization_failures variable; check the result of
        GC_general_register_disappearing_link() (for lack of memory)
        instead.
        * finalize.c (GC_finalization_failures): Remove unused global

        * include/private/gc_pmark.h (PUSH_ONE_CHECKED_STACK,
        GC_PUSH_ONE_STACK, GC_PUSH_ONE_HEAP): The first parameter is of

        after) for configuration information.

        * gcj_mlc.c (GC_gcj_malloc_ignore_off_page): Check "op" local

        * win32_threads.c (GC_register_my_thread, GC_unregister_my_thread):
        Use GC_lookup_thread_inner() instead of GC_lookup_thread() and
        acquire the GC lock only once.
        * win32_threads.c (GC_thr_init): Call GC_register_my_thread_inner()
        directly instead of GC_register_my_thread() since I_HOLD_LOCK

        (cast the result to word type) to decode values of "GC_TRACE",
        "GC_INITIAL_HEAP_SIZE", "GC_MAXIMUM_HEAP_SIZE" environment vars.

2008-07-25  Hans Boehm <Hans.Boehm@hp.com> (Really mostly Ivan Maidanski)
	Ivan's description of the patch follows. Note that a few pieces like
	the GC_malloc(0) patch, were not applied since an alternate had been
	previously applied.  A few differed stylistically from the rest of
	the code (mostly casts to void * instead of target type),
	or were classified as too minor to bother.  Note that
	all of Ivan's static declarations which did not correct outright
	naming bugs (as a few did), where replaced by STATIC, which is
	ignored by default.

        - minor bug fixing (for FreeBSD, for THREAD_LOCAL_ALLOC and for
	  GC_malloc(0));
        - addition of missing getter/setter functions for public variables
	  (may be useful if compiled as Win32 DLL);
        - addition of missing GC_API for some exported functions;
        - addition of missing "static" declarator for internal functions
	   and variables (where possible);
        - replacement of all remaining K&R-style definitions with ANSI
	  C ones (__STDC__ macro is not used anymore);
        - addition of some Win32 macro definitions (that may be missing in
	  the standard headers supplied with a compiler) for GWW_VDB mode;
        - elimination of most compiler warnings (except for
	  "uninitialized data" warning);
        - several typos correction;
        - missing parenthesis addition in macros in some header files of
	  "libatomic_ops" module.

	My highlights based on reading the patch:

	* allchblk.c: Remove GC_freehblk_ptr decl.
	Make free_list_index_of() static.
	* include/gc.h: Use __int64 on win64, define GC_oom_func, 
	GC_finalizer_notifier_proc, GC_finalizer_notifier_proc,
	add getter and setters: GC_get_gc_no, GC_get_parallel,
	GC_set_oom_fn, GC_set_finalize_on_demand,
	GC_set_java_finalization, GC_set_dont_expand,
	GC_set_no_dls, GC_set_max_retries, GC_set_dont_precollect,
	GC_set_finalizer_notifier.  Always define GC_win32_free_heap.
	gc_config_macros.h: Define _REENTRANT after processing
	GC_THREADS.
	* include/gc_cpp.h: Improve GC_PLACEMENT_DELETE test,
	handling of operator new[] for old Windows compilers.
	* include/gc_inline.h (GC_MALLOC_FAST_GRANS): Add parentheses
	around arguments.
	* dbg_mlc.c, malloc.c, misc.c: Add many GC_API specs.
	* mark.c (GC_mark_and_push_stack): Fix source argument for
	blacklist printing.
	* misc.c: Fix log file naming based on environment variable
	for Windows.  Make GC_set_warn_proc and GC_set_free_space_divisor
	just return current value with 0 argument.  Add DONT_USER_USER32_DLL.
	Add various getters and setters as in gc.h.
	* os_dep.c: Remove no longer used GC_disable/enable_signals
	implementations.  (GC_get_stack_base): Add pthread_attr_destroy
	call.  No longer set GC_old_bus_handler in DARWIN workaround.
	* pthread_support.c: GC_register_my_thread must also
	call GC_init_thread_local.
