	* finalize.c (GC_check_finalizer_nested): Change return type to
	char pointer (instead of int pointer); use explicit cast for
	GC_finalizer_nested assignment.
	* pthread_support.c (GC_check_finalizer_nested): Ditto.
	* win32_threads.c (GC_check_finalizer_nested): Ditto.
	* finalize.c (GC_finalizer_nested): Change type to unsigned char.
	* finalize.c (GC_notify_or_invoke_finalizers): Change type of
	"pnested" local variable to char pointer.
	* pthread_support.c (GC_do_blocking_inner,
	GC_call_with_gc_active): Use explicit cast for "thread_blocked"
	field assignment.
	* win32_threads.c (GC_lookup_pthread): Use explicit cast for
	"suspended" field assignment.
	* win32_threads.c (GC_Thread_Rep): Use short type for
	finalizer_skipped; use char type for finalizer_nested and flags
	fields and reorder some fields (to minimize GC_Thread_Rep
	structure size).
	* include/private/pthread_support.h (GC_Thread_Rep): Ditto.
	* win32_threads.c (GC_Thread_Rep): Use char type for suspended
	field (instead of GC_bool).
	* include/private/pthread_support.h (GC_Thread_Rep): Use char type
	for thread_blocked field (instead of short).
