#2289: Problem with BOOST_AUTO and this keyword on VC8/9

Milestone:  Boost 1.37.0                                 |   Component:  typeof     
  Version:  Boost 1.36.0                                 |    Severity:  Problem    
 Keywords:                                               |  
---------------------------------------------------------+------------------
 On both VC8SP1 and VC9SP1, the code

 {{{
 struct foo
 {
         int i;

         foo::foo()
         {
                 BOOST_AUTO(j, this->i);
         }
 };
 }}}


 results in the compiler error

 {{{

 error C2355: 'this' : can only be referenced inside non-static member
 functions
 error C2227: left of '->i' must point to class/struct/union/generic type

 error C2955: 'boost::type_of::msvc_typeid_wrapper' : use of class template
 requires template argument list
         e:\boostsvn\boost\typeof\msvc\typeof_impl.hpp(209) : see
 declaration of 'boost::type_of::msvc_typeid_wrapper'
 }}}

 In both cases, changing it to simply BOOST_AUTO(j, i); allows it to
 compile.

 The foreach lib used to have a similar problem (Ticket #1652), possibly
 down to the same compiler bug?
