cppexp.c (cpp_interpret_integer, [...]): Clarify and correct use of "bool" variables.

	* cppexp.c (cpp_interpret_integer, append_digit, parse_defined,
	eval_token): Clarify and correct use of "bool" variables.
	* cpplib.h (struct cpp_options): Similarly.
	* cppmacro.c (parse_params, _cpp_save_parameter): Ditto.
	* cpptrad.c (recursive_macro): Similarly.
