SA_RESETHANDLER test

Build

$ make

Run

On AIX it looks like the signal handler doesn't get the expected signal in the second argument (siginfo_t*) if the signal handler is installed with SA_RESETHANDLER.

$ ./signals
raise SIGUSR1 signal
signo 30 si_signo 0 si_code 0
$

Expected behaviour

Expect the si_signo field of the second argument to be equal to the first argument.
