* search.c (lookup_field_1): Look through USING_DECL.
(lookup_field_r): Call lookup_fnfields_slot instead of
lookup_fnfields_1.
* semantics.c (finish_member_declaration): Remove the check that
prevents USING_DECLs from being verified by
pushdecl_class_level. Call add_method for using declarations that
designates functions if the using declaration is in a template
class. Set DECL_IGNORED_P on class-scope using declarations.
* typeck.c (build_class_member_access_expr): Handle USING_DECLs.
* class.c (check_field_decls): Keep using declarations.
(add_method): Remove two diagnostics about conflicting using
declarations.
* parser.c (cp_parser_nonclass_name): Handle USING_DECLs.
* decl.c (start_enum): Call xref_tag whenever possible.
* cp-tree.h (strip_using_decl): Declare, and reident the previous
function.
* name-lookup.c (strip_using_decl): New function.
(supplement_binding_1): Call strip_using_decl on decl and
bval. Perform most of the checks with USING_DECLs stripped. Also
check that the target decl and the target bval does not refer to
the same declaration. Allow pushing an enum multiple times in a
template class. Adjustment to diagnose using redeclarations. Call
diagnose_name_conflict.
(push_class_level_binding): Call strip_using_decl on decl and
bval. Perform most of the checks with USING_DECLs stripped. Return
true if both decl and bval refer to USING_DECLs and are dependent.
(diagnose_name_conflict): New function.

The code:
struct A {int* next; };
struct B {int* next; };
struct C : public A, public B { using A::next; };
void foo(C* c) { c->next = 0; }
gets you:
~/ootbc/sim$ g++ foo.cc
foo.cc: In function `void foo(C*)':
foo.cc:4: error: request for member `next' is ambiguous
foo.cc:2: error: candidates are: int*B::next
foo.cc:1: error: int*A::next
Compiles OK on Comeau.
