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.
