Warning fixes:

* Makefile.in (cvt.o): Depend on toplev.h.
        * cp-tree.h (check_template_shadow, pod_type_p): Add prototypes.
        * cvt.c: Include toplev.h.
        * except.c (get_eh_caught, get_eh_handlers): Hide prototypes and
        definitions.
        * init.c (expand_vec_init): Initialize variable `itype'.
        * lex.c (yyerror): Cast the argument passed to a ctype function to
        an unsigned char.
        * method.c (build_mangled_C9x_name): Wrap prototype and definition
        in "HOST_BITS_PER_WIDE_INT >= 64".
        * typeck.c (build_binary_op): Mark parameter `convert_p' with
        ATTRIBUTE_UNUSED.
