2001-09-20 Michael Snyder <msnyder@redhat.com>
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.
