That isn't what the comment says though:
SA_SIGINFO [...]
If cleared and the signal is caught, the first argument is
also the signal number but the second argument is the signal
code identifying the cause of the signal. The third argument
points to a sigcontext_t structure containing the receiving
process's context when the signal was delivered. */

OK, I see, so there is a single prototype for the 2 variants with 3 args.
