* cp-tree.h (vtbl_ptr_type_node): New variable.
* class.c (build_vtbl_ref): Don't indirect through the vptr; it's
already of the right type.
(finish_struct_1): Make the vptr be of type vtbl_ptr_type_node.
Simplify code to grow vtable.
* decl.c (vtbl_ptr_type_node): Define.
(init_decl_processing): Initialize it.
I get lots of these errors trying to build libio:
../../../devo/libio/iostream.h: In method `ostream::ostream()':
In file included from ../../../devo/libio/fstream.h:30,
from ../../../devo/libio/fstream.cc:34:
../../../devo/libio/iostream.h:49: assignment to `const __vtbl_ptr_type *' from
`const __vtbl_ptr_type (*)[2]'
I happen to be working with a PA compiler, but I've also seen it with a mn102
cross compiler (hppa1.1-hp-hpux10 or mn10200-elf). No compiler arguments are
necessary.
