- raise() no longer resets the signal handler before it invokes the one

currently configured. It merely blocks the delivery of the respective
  signal to prevent recursion.

- raise() now drops into abort() if a signal handler is set to
  SIG_DFL. The exception is in SIGINT delivery, which has the
  effect of printing a different termination message but otherwise
  program flow takes the same path as abort().
