 Upon closer inspection, I believe that this high priority regression is 
 actually another manifestation of (high priority regression) c++/8117. The 
 testcase for the latter is 
 ---------------------
 struct A { virtual void foo() = 0; };
 
 struct B : A {};
 struct C : A {};
 
 struct D : B, C { virtual void foo() {} };
 
 void (D::* p)() = &D::foo;  // 'A' is an ambiguous base of 'D'
 --------------------
 while for the former
 --------------------
 struct A { int i; };
 struct B {};
 class E : A, B { public: using A::i; };
 
 void foo() { E().i; } // "`A' is an inaccessible base of `E'"
 ---------------------
 
 The theory that they are the same is also supported by the fact that both 
 started to show up somewhere between 2001-11-25 and 2001-12-01.
