Patch: cleanup for new GC

[Tom Tromey <tromey at cygnus dot com>]

I'm checking in the appended patch.  It makes libgcj operate more
smoothly with the newly imported GC.

1999-11-01  Tom Tromey  <tromey@cygnus.com>

	* boehm.cc (_Jv_InitGC): Set GC_java_finalization.
	(sum_blocks): Removed.
	(_Jv_GCFreeMemory): Use GC_get_free_bytes.
