Warning fixes:

        * c-lex.c (yylex): Remove unused variable `bytes'.
        * flow.c (print_rtl_with_bb): Cast the return value of alloca.
        * function.c (assign_parms): Wrap variable `varargs_setup' in
        macro SETUP_INCOMING_VARARGS.
        (thread_prologue_and_epilogue_insns): Mark parameter `f' with
        ATTRIBUTE_UNUSED.
        * local-alloc.c (no_equiv): Likewise for parameter `store'.
        * sched.c (schedule_insns): Remove unused variables `insn' and `next'.
        * tlink.c (symbol_hash_newfunc, symbol_hash_lookup,
        file_hash_newfunc, file_hash_lookup, demangled_hash_newfunc,
        demangled_hash_lookup, symbol_push, symbol_pop, file_push,
        file_pop, tlink_init, tlink_execute, frob_extension,
        obstack_fgets, tfgets, pfgets, freadsym, read_repo_file,
        maybe_tweak, recompile_files, read_repo_files,
        demangle_new_symbols, scan_linker_output): Add static prototype.
        (symbol_hash_newfunc, file_hash_newfunc, demangled_hash_newfunc):
        Make the third argument a `hash_table_key'.
        * toplev.c (debug_start_source_file): Mark parameter `filename'
        with ATTRIBUTE_UNUSED.
