WinCE (since backtrace() is unimplemented).
* include/private/gc_priv.h (GC_n_heap_bases): Remove declaration
(since static).
* os_dep.c (GC_n_heap_bases): Define as STATIC; move the
definition to be above GC_is_heap_base().
* include/private/gcconfig.h: Don't define NOSYS for WinCE on ARM
(both for MinGW and CeGCC toolchains).
* include/private/gcconfig.h: Recognize __CEGCC__ and
__MINGW32CE__ (as synonyms for __WIN32_WCE).
* include/private/gcconfig.h: If SH4 then don't set config
parameters for SH.
* include/private/thread_local_alloc.h (GC_key_create): Don't
abort on failures, just return -1 in these cases (this also
prevents compilation error for targets where ABORT is defined
indirectly as an inline assembler sequence).
* mark.c (WRAP_MARK_SOME): Also define for WinCE; add FIXME for
the GCC-based cross-compiler.
* mark.c (ext_ex_regn, mark_ex_handler): Don't define unless
WRAP_MARK_SOME is defined; define also for WinCE case; don't
check for _WIN64 (since WRAP_MARK_SOME is undefined for it).
* mark.c (GC_mark_some): Use __try/__except also for WinCE; update
the comment.
* misc.c: Include signal.h after gc_pmark.h included; check for
MSWINCE instead of _WIN32_WCE.

TINY_REVERSE_UPPER_VALUE macro (4 if VERY_SMALL_CONFIG else 10);
useful for WinCE.
* win32_threads.c (GC_Thread_Rep): Don't declare "handle" field
for WinCE (since thread Id is used as a "real" thread handle).
* win32_threads.c (THREAD_HANDLE): New macro.
* win32_threads.c (GC_register_my_thread_inner): Don't recognize
DONT_IMPORT_GETCURTHREAD anymore; don't record thread handle on
WinCE.
* Makefile.direct (DONT_IMPORT_GETCURTHREAD): Remove comment for.
* win32_threads.c (UNPROTECT, GC_fault_handler_lock): Don't check
for MSWINCE.

close thread handle on WinCE (since it's a thread Id).
* win32_threads.c (GC_suspend): Don't check for MSWINCE in the
MPROTECT-related code (for the case if MPROTECT_VDB would be
implemented for WinCE).
* win32_threads.c (GC_suspend, GC_start_world, GC_push_stack_for):
Use THREAD_HANDLE(t) to obtain thread handle.
* win32_threads.c (GC_PTHREADS_PARAMARK): New macro recognized;
implicitly define GC_PTHREADS_PARAMARK if GC_PTHREADS; include

GC_PTHREADS with GC_PTHREADS_PARAMARK where appropriate (for the
parallel mark support).
* win32_threads.c (start_mark_threads): Use int type for "i" local
variable (instead of "unsigned") to prevent a compiler warning.
* win32_threads.c (start_mark_threads): Don't check CreateThread()
result for -1; call CloseHandle() for the handle created by
CreateThread() (on WinCE); don't use errno (since errno.h is
missing on some targets like WinCE) when printing warning on a
marker thread creation failure.
* win32_threads.c (signalObjectAndWait_func): Define for WinCE.
* win32_threads.c (GC_wait_marker): Remove unnecessary assertion
for non-zero signalObjectAndWait_func (to make the code compilable
for WinCE).
* win32_threads.c (GC_thr_init): Allow PARALLEL_MARK for WinCE;
use GC_sysinfo to get processors count if WinCE; don't check for
SignalObjectAndWait() if WinCE; replace GC_PTHREADS with

macro (useful for testing parallel marking on WinCE).

main_thread_start(), WinMain() for WinCE if GC_DLL.
* win32_threads.c (WINCE_MAIN_STACK_SIZE): Remove useless macro
(since the stack size parameter is ignored on WinCE).
* win32_threads.c (main_thread_start): Remove forward declaration;
place its definition before WinMain() one.
* win32_threads.c (WinMain): Abort if GC_CreateThread() or
WaitForSingleObject() failed (for the main thread).

* allchblk.c (GC_unmap_threshold): New global variable definition
(initialized to MUNMAP_THRESHOLD).

MUNMAP_THRESHOLD; skip unmapping if GC_unmap_threshold is 0.

GC_debug_register_finalizer_no_order,
GC_debug_register_finalizer_unreachable,
GC_debug_register_finalizer_ignore_self): Initialize my_old_fn
to OFN_UNSET; clear *ocd and *ofn for non-heap objects (the same
as in GC_register_finalizer_inner()).
