typeck.c (complete_type_or_else): Add VALUE arg, for helpful diagnostics.
* typeck.c (complete_type_or_else): Add VALUE arg, for helpful
diagnostics.
cp-tree.h (complete_type_or_else): Added VALUE parameter.
* init.c (build_new_1): Extra arg to complete_type_or_else.
(build_delete): Likewise.
* typeck.c (require_complete_type): Likewise.
(pointer_int_sum): Likewise.
(pointer_diff): Likewise.
(build_component_ref): Likewise.
* typeck2.c (incomplete_type_error): Always use cp_error.
Show declaration of undefined type, if appropriate.
Deal with UNKNOWN_TYPE nodes.
* typeck.c (require_complete_type): Use TYPE_SIZE as
size_zero_node to mean incomplete type.
(require_complete_type_in_void): New function.
(build_compound_expr): Call complete_type_in_void for LHS.
(build_c_cast): Call complete_type_in_void for void cast.
* cvt.c (ocp_convert): Call complete_type_in_void for void cast.
* decl.c (cplus_expand_expr_stmt): Void expression checks moved to
require_complete_type_in_void. Call it.
* cp-tree.h (require_complete_type_in_void): Prototype new function.
* typeck.c (convert_arguments): Use alternative format for function
decls. Don't require_complete_type here. Simplify diagnostic printing.

* call.c (print_z_candidates): Use alternate print format, to be
consistant with (pt.c) print_candidates.
method.c (hack_identifier): List candidate members.
search.c (lookup_field): Build ambiguous list, and show it, if
ambiguous.
