[boost] [Program Options] fix for #6797 breaks compilation

Subject: [boost] [Program Options] fix for #6797 breaks compilation

Hi Volodya,

the fix for #6797 in 4ae33ce15e5b6345e6eefa19466fdf7cd28a7bbd breaks compilation 
if Boost.ProgramOptions on msvc-11.0 and -12.0. See full error log with msvc-11.0 
attached.
It seems that the export macros changes the template evaluation somehow, so msvc 
now  needs "decrement" and "advance" member. The short error is:

E:\dev\devel\boost\boost/iterator/iterator_facade.hpp(402) :
error C2039: 'decrement' : is not a member of 
'boost::program_options::detail::common_config_file_iterator'

E:\dev\devel\boost\boost/iterator/iterator_facade.hpp(420) :
error C2039: 'advance' : is not a member of 
'boost::program_options::detail::common_config_file_iterator'

I'm not sure how to implement at least empty stubs or if this can be otherwise worked 
around.

Yours,

Jürgen
