	* 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.
