non-NULL (instead of calling GetThreadContext()); "UNPROTECT" the
thread before modifying its last_stack_min; call
GC_push_all_stack_frames() instead of GC_push_all_stack(); update
the comments.

(ivmai129.diff - superseding diff47)
* alloc.c (GC_default_stop_func): New static variable (initialized
to GC_never_stop_func).
* alloc.c (GC_set_stop_func, GC_get_stop_func): New function.
* alloc.c (GC_timeout_stop_func): Define as GC_default_stop_func
(instead of GC_never_stop_func) if SMALL_CONFIG (or NO_CLOCK),
else call GC_default_stop_func() before getting "current_time".
* alloc.c (GC_maybe_gc): Expand GC_gcollect_inner() macro (for
FIXME comment).
* alloc.c (GC_maybe_gc, GC_collect_a_little_inner): add FIXME for
replacing GC_never_stop_func with GC_default_stop_func (if
possible).
* alloc.c (GC_gcollect): Use GC_default_stop_func.
* alloc.c (GC_collect_or_expand): Use GC_default_stop_func
(instead of GC_never_stop_func) unless it is trigged due to out of
memory; don't increment GC_fail_count and don't output warning
(before trying to collect again) in case the collection has been
interrupted (by GC_default_stop_func) and the heap expansion has
failed too.
* include/gc.h (GC_set_stop_func, GC_get_stop_func): New function
prototypes.

* include/private/gcconfig.h (GWW_VDB): Undefine if
USE_GLOBAL_ALLOC (since incompatible).
* os_dep.c (GetWriteWatch_alloc_flag): Define as 0 unless GWW_VDB
is defined.
* os_dep.c (GC_unmap_threshold): Declare (for use in
GC_init_win32) if USE_MUNMAP.
* os_dep.c (GC_init_win32): Turn off memory unmapping if
GlobalAlloc() is used.
* os_dep.c (GC_win32_get_mem): Define and use new
VIRTUAL_ALLOC_PAD macro; don't waste a extra memory page unless
MPROTECT_VDB is in use.

* allchblk.c (GC_allochblk_nth): Use GC_PRIdPTR in WARN() format
string.
* pthread_support.c (start_mark_threads, GC_thr_init): Ditto.
* win32_threads.c (GC_delete_thread): Ditto.
* include/private/gc_priv.h (GC_PRIdPTR): New macro.
* pthread_stop_world.c (GC_suspend_handler_inner): Remove
unnecessary cast for WARN argument.
* pthread_support.c (start_mark_threads): if pthread_create()
failed then don't try to create other marker threads and (after
printing a warning) adjust GC_markers and GC_parallel values; log
GC_markers value (possibly adjusted) after that.

* win32_threads.c (start_mark_threads): if pthread_create() is
failed then don't try to create other marker threads and (after
printing a warning) adjust GC_markers and GC_parallel values.
* win32_threads.c (mark_mutex_event, builder_cv, mark_cv): Move
the definition upper (to be visible in start_mark_threads()).
* win32_threads.c (start_mark_threads): if CreateThread() or
_beginthreadex() is failed then don't try to create other marker
threads and (after printing a warning) adjust GC_markers,
GC_parallel values, and destroy the event objects (either only
some for the uncreated threads if DONT_USE_SIGNALANDWAIT or all if
not a single thread is created).
* win32_threads.c (GC_thr_init): Log GC_markers value (possibly
adjusted) after start_mark_threads() call.

* finalize.c (GC_general_register_disappearing_link): Return
GC_SUCCESS, GC_DUPLICATE, GC_NO_MEMORY (instead of 0, 1 and 2,
respectively).
* include/gc.h (GC_NO_MEMORY): New macro (defined as 2).
* include/gc.h (GC_register_disappearing_link,
GC_general_register_disappearing_link): Update the comment.
* typd_mlc.c (GC_calloc_explicitly_typed): Use GC_NO_MEMORY macro.
* finalize.c (GC_general_register_disappearing_link,
GC_register_finalizer_inner): Recalculate the hash table index
after GC_oom_fn succeeded (since the table may grow while not
holding the lock) and check again that the entry is still not in
the table (free the unused entry otherwise unless DBG_HDRS_ALL).
* finalize.c (GC_register_finalizer_inner): Initialize "hhdr"
local variable (to prevent a compiler warning).
* finalize.c (GC_register_finalizer_inner): Don't modify the data
pointed by "ocd" and "ofn" in GC_register_finalizer_inner() failed
(due to out of memory).
