dnl Allows a signal handler to throw a C++ exception if the signal is from
dnl a CPU trap on an instruction (ex. SIGFPE from a floating point divide
dnl by zero). This allows the signal handler to transfer control to the
dnl catch block wrapping the area which errored, thereby aborting any further
dnl execution after the signal was received which would have to manually check
dnl for such an error after each floating point operation and throw.
