* 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'.
