11012,chrono_io v2 fail to compile with  boost::chrono::duration< boost::rational<int> >,Sébastien Barthélémy <barthelemy@…>,viboes,"When using

{{{
 boost::chrono::duration< boost::rational<int> >
}}}

as duration type, chrono_io v2 fails to build with error
{{{
include/boost/chrono/io/duration_units.hpp:136:91: error: invalid static_cast from type ‘boost::chrono::duration<boost::rational<int> >::rep {aka boost::rational<int>}’ to type ‘intmax_t {aka long int}’
}}}

while chrono_io v1 builds and works as expected.

Here is the full compilation log for the attached example.
