5855	narrowing conversion error with -std=c++0x in operator< with int_type != int	mlang@…	Jonathan Turkanis	"With GCC (4.6) and -std=c++0x, there are several narrowing conversion errors in operator<
if int_type is different from int, for example, short int.
Example:
#include <boost/rational.hpp>
int main() { return boost::rational<short int>() < boost::rational<short int>(); }
Error output:
/tmp/boost/boost/rational.hpp: In member function ‘bool boost::rational<IntType>::operator<(const boost::rational<IntType>&) const [with IntType = short int]’:
/tmp/boost/boost/rational.hpp:393:39: error: narrowing conversion of ‘(((int)((const boost::rational<short int>*)this)->boost::rational<short int>::num) / ((int)((const boost::rational<short int>*)this)->boost::rational<short int>::den))’ from ‘int’ to ‘boost::rational<short int>::int_type {aka short int}’ inside { } [-fpermissive]
/tmp/boost/boost/rational.hpp:393:39: error: narrowing conversion of ‘(((int)((const boost::rational<short int>*)this)->boost::rational<short int>::num) % ((int)((const boost::rational<short int>*)this)->boost::rational<short int>::den))’ from ‘int’ to ‘boost::rational<short int>::int_type {aka short int}’ inside { } [-fpermissive]
