Warning fixes:

        * alias.c (record_alias_subset): Remove ignored `&'.
        (init_alias_once): Likewise.
        * c-lex.c (UNGETC): Cast first argument of comma expression to void.
        * config/mips/mips.c (mips_asm_file_end): Cast the result of
        fwrite to `int' when comparing against one.
        * config/mips/mips.h (CAN_ELIMINATE): Add parens around && within ||.
        (INITIAL_ELIMINATION_OFFSET): Add braces to avoid ambiguous `else'.
        * cse.c (rehash_using_reg): Change type of variable `i' to
        unsigned int.
        * dwarf2out.c (initial_return_save): Cast -1 to unsigned before
        assigning it to one.
        * except.c (duplicate_eh_handlers): Remove unused variable `tmp'.
        * final.c (final_scan_insn): Likewise for variable `i'.
        (output_asm_insn): Cast a char to unsigned char when used as an
        array index.
        * gcse.c (compute_pre_ppinout): Cast -1 to SBITMAP_ELT_TYPE when
        assigning it to one.
        * loop.c (strength_reduce): Remove unused variables `count' and `temp'.
        * recog.c (preprocess_constraints): Cast a char to unsigned char
        when used as an array index.
        * regmove.c (find_matches): Likewise.
        * reload1.c (calculate_needs): Add default case in switch.
        (eliminate_regs_in_insn): Initialize variable `offset'.
        (set_offsets_for_label): Change type of variable `i' to unsigned.
        (reload_as_needed): Wrap variable `i' in macro check on
        AUTO_INC_DEC || INSN_CLOBBERS_REGNO_P.
        * scan-decls.c (scan_decls): Mark parameters `argc' and `argv'
        with ATTRIBUTE_UNUSED.  Cast variable `start_written' to size_t
        when comparing against one.
        * stor-layout.c (layout_decl): Cast maximum_field_alignment to
        unsigned when comparing against one.  Likewise for
        GET_MODE_ALIGNMENT().
        (layout_record): Cast record_align to int when comparing against a
        signed value.
        (layout_type): Cast TYPE_ALIGN() to int when comparing against a
        signed value.
        * tree.c (get_identifier): Cast variable `len' to unsigned when
        comparing against one.
        (maybe_get_identifier): Likewise
