I guess christos means "in the application" here.
For example, Solaris 8 doesn't define SA_INTERRUPT at all.
So, portable programs shouldn't assume that SA_INTERRUPT is defined.

This sentence is somewhat ambiguous.
Actually,
- We have SA_RESTART == 2 which means opposite of SA_INTERRUPT.
- The feature of SA_INTERRUPT is "ON" by default.

This default setting is not only on NetBSD.
Solaris, Linux, and nearly all modern UNIX use this default.

This works as christos said.
But perhaps it's better to do something like the following:

	#if defined(SA_INTERTUPT)
		sa.sa_flags = SA_INTERTUPT; /* somewhat old system??? */
	#elif defined(SA_RESETHAND)
		sa.sa_flags = 0; /* modern system */
	#else
		XXX FIXME
	#endif

This is wrong.
