Warning fixes:

	* actions.c (id_cmp): Do pointer arithmetic as `long' not `int' to
 	ensure enough bits for calculation.
	* ch-tree.h (check_text_length): Remove unused parameter.
	* convert.c (display_int_cst): Cast a HOST_WIDE_INT argument to
	function sprintf into the appropriate type for printing.
	* decl.c (print_lang_decl): Use HOST_WIDE_INT_PRINT_DEC as the
	format specifier.
	(print_mode): Likewise.
	(init_decl_processing): Cast the arguments of bcopy/bzero to char *.
	* grant.c (grant_array_type): Use HOST_WIDE_INT_PRINT_DEC as
	the format specifier.
	* inout.c (check_text_length): Remove unused parameter `type'.
	(build_chill_associate): Initialize variables `arg1', `arg2',
	`arg3', `arg4' and `arg5'.
	(build_chill_modify): Likewise.
	(scanformcont): Change type of variable `curr' to `unsigned char'.
	* lex.c (maybe_downcase): Cast the argument of `tolower' to
	`unsigned char'.
	* satisfy.c (satisfy): Remove unused parameter in call to
	`check_text_length'.
	* tasking.c (generate_tasking_code_variable): Pass a HOST_WIDE_INT
	as a `long' in call to function `error'.
	(decl_tasking_code_variable): Likewise.
