Warning fixes:

        * Makefile.in (varasm.o): Depend on sdbout.h.
        (sdbout.o): Depend on toplev.h.
        * collect2.c (scan_prog_file): Cast fprintf argument to `long' and
        use %ld specifier.
        * final.c (shorten_branches): Cast first arg of `bzero' to char *.
        * genextract.c (main): When creating insn-extract.c, mark variable
        `i' with ATTRIBUTE_UNUSED.
        * genpeep.c (main): When creating insn-peep.c, mark variables
        `insn', `x' and `pat' with ATTRIBUTE_UNUSED.
        * objc/init.c (__objc_tree_print): Wrap function definition in
        macro `DEBUG'.
        * objc/objc-act.c (encode_array): Cast sprintf argument to `long'
        and use %ld specifier.
        (adorn_decl): Likewise, twice.
