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.
