Error description

• The following redueced test case gives out invalid name lookup
  error message compiled on xlC:
  
  /* nt.cpp */
  struct Base  {};
  
  struct Fifo{
     void end();
  };
  
  // 38
  struct FifoWithSync2:public Fifo{
        typedef Fifo Base;
  
        Fifo* other() const;
        void end() {
           // 57 (S)
          other()->Base::end();
        }
  };
  
  $xlC nt.cpp
  
  "nt.cpp", line 16.18: 1540-0259 (S) The name lookups of "Base"
  do not yield the same type in the context of the expression and
  in the context of the class of the object expression.
  "nt.cpp", line 16.18: 1540-1209 (I) The name lookup in the
  context of "struct Fifo" resolved to "struct Base".
  "nt.cpp", line 16.18: 1540-1210 (I) Name lookup in the context
  of the expression resolved to "FifoWithSync2::Base".
  

Local fix

• Change the tydef statement to another name, or remove it
  altogether.
  
  For example:
  
        typedef Fifo Base1;
  
        ...
  
        other()->Base1::end();
  
  
  Or
  
       // typedef Fifo Base;
  
        ...
  
        other()->Fifo::end();
  

Problem summary

• USER AFFECTED:
  The problem will only happen on a member access (. or ->)
  followed by a qualified name, when there is more
  than one name found by name lookup.
  
  PROBLEM DESCRIPTION:
  An incorrect name lookup caused the compiler to pick
  two names and report them in conflict.
  

Problem conclusion

• The issue with name lookup has been fixed.
  

Temporary fix
