 * All the STOP statements in the Fortran routines have been replaced

 *
 * The XSTOPX function calls this function, which will send a SIGINT
 * signal to the program that invoked it.
 *
 * Octave\'s SIGINT signal handler calls jump_to_top_level(), and the
 * user will end up at the top level instead of the shell prompt.
 *
 * Programs that don\'t handle SIGINT will be interrupted.
