the GCC-based cross-compiler.

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
pthread.h; define NUMERIC_THREAD_ID(id) if undefined yet; replace
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).

place its definition before WinMain() one.

it's missing there);

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_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.
