	gcc            : ChangeLog collect2.c flow.c loop.c reload.c 
	                 reload1.c 

Log message:
	* collect2.c (scan_prog_file, scan_libraries): Prototype function
	pointers and casts for `int_handler' and `quit_handler'.
	
	* flow.c (verify_flow_info, split_hard_reg_notes,
	find_insn_with_note, sets_reg_or_subreg_1, prepend_reg_notes,
	remove_edge, remove_fake_successors): Add static prototypes.
	(verify_flow_info): Wrap with macro ENABLE_CHECKING.
	(mark_set_1): Initialize variable `regno'.
	(unlink_insn_chain): Likewise for variable `curr'.
	(remove_fake_edges): Remove unused variables `e', `tmp' and `last'.
	
	* loop.c (strength_reduce): Initialize variable
	`unrolled_insn_copies'.
	(cmp_combine_givs_stats, cmp_recombine_givs_stats): Add static
	prototypes.  Change these functions to take const PTR parameters
	to avoid prototype conflict when used as the comparson argument
	for qsort.
	(check_dbra_loop): Initialize variable `comparison_val'.
	
	* reload.c (debug_reload_to_stream, debug_reload): Add prototypes.
	(get_secondary_mem): Mark parameter `x' with ATTRIBUTE_UNUSED.
	(find_valid_class): Initialize variable `best_class'.
	(find_reloads): Call memcpy, not bcopy.
	
	* reload1.c (gen_mode_int, dump_needs): Add prototypes.
	(hard_reg_use_compare): Don't needlessly cast away const.
	(reload_reg_class_lower): Likewise.
	(choose_reload_regs): Initialize variable `regno'.
