This is unportable.

If you want automatic zombie reaping, better don't use the simplified
signal(3) handling, but instead spell it out as sigaction(2) using the
SA_NOCLDWAIT flag.  The above won't even give you a warning on systems
that don't implement automatic zombie reaping, while with sicaction,
you'll get a compile-time error for SA_NOCLDWAIT not being defined.
