Comment:

 I got some other warnings when compiling options_description_test.cpp:
 {{{
 ../../../boost/any.hpp: In member function ‘void
 boost::program_options::typed_value<T, charT>::notify(const boost::any&)
 const [with T = double, charT = char]’:
 options_description_test.cpp:182:   instantiated from here
 ../../../boost/any.hpp:216: warning: type qualifiers ignored on function
 return type
 ../../../boost/any.hpp: In member function ‘void
 boost::program_options::typed_value<T, charT>::notify(const boost::any&)
 const [with T = int, charT = char]’:
 options_description_test.cpp:182:   instantiated from here
 ../../../boost/any.hpp:216: warning: type qualifiers ignored on function
 return type
 }}}

 Probably these warnings point to a real bug (changed type to "bug" until
 it is clear).

 I compiled "by-hand" with:
 {{{
 g++ options_description_test.cpp \
    -g -Wall -Wextra -pedantic -I../../.. -L/my/private/libdir
 -lboost_program_options -o a.out
 }}}

 I'm not quite sure, but I think any_cast is used in a wrong way. I added
 any_cast_warning.patch which should solve this problem ... but please
 review!

 Thanks
