        * boehm-gc/include/gc.h: (GC_CreateThread) This function is
        now exposed on all Win32 platforms.
        * boehm-gc/win32_threads.c: (GC_CreateThread) This now
        compiles on Win32; it invokes CreateThread() if GC is built
        as a DLL; otherwise it registers the thread.
        * boehm-gc/misc.c (GC_init): Initialize GC_allocate_ml in case
        libgcjgc was not built as a DLL.

	* misc.c: Back out buggy changes to stack clearing code.
	Reduce CLEAR_SIZE to 1/4 of original value to reduce time
	spent clearing memory.

	* finalize.c:
	- Accomodate finalization requests for static objects.
	  (Will be required by hash synchronization.  May be needed
	  in some configurations now.)

	* gc_priv.h:
	- Define MIN_WORDS.  All allocation requests are rounded
	  up to at least this size.  Removes a subtle assumption that
	  Java objects have a 2 word header.

	* gcconfig.h:
	- Adjust Linux/IA64 configuration for non-ancient kernels.
	  (Necessary fix for IA64.)

	* linux_threads.c:
	- Fix syntax error in currently unused code.  Will be needed
	  for Linux/PA-RISC.

	* malloc.c:
	- Handle MIN_WORDS.

	* misc.c:
	- Handle MIN_WORDS.
	- Change stack cleaning code to typically clear about one tenth
	  the memory it used to in the threads configuration.  Occasionally
	  still clear more.  (This is really a fix for a long-standing
	  and fairly significant performance bug with threads.)

	* os_dep.c:
	- Fix the code for finding the beginning of the data segment under
	  Linux.  I believe this is necessary for some IA64 Linux
	  distributions.  It will also helo other platforms, though those
	  may additionally require a gcconfig.h adjustment.  (This basically
	  works around the absence of a data_start or __data_start
	  definition in glibc.)

	* test.c:
	- Handle rounding due to MIN_WORDS.

	GC_stackbottom.
