Comment (by Jeffrey Hellrung <jeffrey.hellrung@…>):

 I have uploaded a patch for iterator_facade.hpp, but I'm having issues
 uploading a patch for iterator_facade.cpp (from libs/iterator/test).  The
 spam filter keeps thinking I'm uploading spam :(  I guess I will email the
 attachment directly to you, Dave, and if it gets lost in the shuffle, I
 can try uploading again...

 The test fails for the present version of iterator_facade with

 compile-c-c++
 ..\..\..\bin.v2\libs\iterator\test\iterator_facade.test\msvc-9.0\debug
 \threading-multi\iterator_facade.obj
 iterator_facade.cpp
 D:\boost_1_47_0\boost/iterator/iterator_facade.hpp(327) : error C2664:
 'boost::implicit_cast' : cannot convert parameter 1 from 'wrapper<T> *' to
 'boost::detail::operator_arrow_proxy<T>'
         with
         [
             T=int &
         ]
         and
         [
             T=wrapper<int>
         ]
         No constructor could take the source type, or constructor overload
 resolution was ambiguous

 ...as expected.
