	* gmon/gmon.c (__bb_head): new variable.
	(write_hist, write_call_graph, write_bb_counts): new functions.
	(_mcleanup): modified to call above functions instead of directly
 	writing out gmon.out.
	* gmon/sys/gmon.h (struct __bb): New type.
	(struct gmonhdr): Type removed.
	(struct gmonparam): New member `log_hashfraction'.
	(GMONVERSION): Macro removed.
