* dwarf2out.c (dwarf2out_line): Constify `lastfile'.

        * except.c (expand_rethrow): Remove unused variable.
        * expr.c (do_jump_by_parts_greater_rtx): Likewise.
        * flow.c (replace_insns): Likewise.
        (create_edge_list, verify_edge_list): Likewise.
        * gcse.c (cprop_cc0_jump): Protect declaration with HAVE_cc0.

        * genemit.c (gen_expand): Only emit `operands[N]' decl if there
        is special code to run.
        (main): Don't define operands to emit_operand.
        * genrecog.c (main): Don't emit an empty peephole2_insn function.

        * rtl.h (NOTE_BASIC_BLOCK): Use X0BBDEF.

        * alpha/alpha.h (normal_memory_operand): Declare.
        (reg_no_subreg_operand): Declare.
        * alpha/elf.h (ASM_DECLARE_OBJECT_NAME): Use HOST_WIDE_INT_PRINT_DEC.
