furthermore, <limits> has been defined so that numeric_limits<int>::traps reports true when division by zero traps. // GCC only intrinsicly supports modulo integral types. The only remaining // integral exceptional values is division by zero. Only targets that do not // signal division by zero in some "hard to ignore" way should use false. #ifndef __glibcxx_integral_traps # define __glibcxx_integral_traps true #endif -- Gaby
