	Changes by Daniel Berlin  <dan@cgsoftware.com>, to support
	better parsing of const and volatile type expressions.
	* c-exp.y (const_and_volatile, const_or_volatile_noopt,
	const_or_volatile): New non-terminals.
	(ptype): Use new rule for const_or_volatile.
	(typebase): Use new rule for const_or_volatile_noopt.
	* parser-defs.h (enum type_pieces): New values tp_const, tp_volatile.
	* parse.c (follow_types): Handle tp_const and tp_volatile on the
        type stack: call make_cv_type to create new const/volatile type.
