But it is. In particular, it's a failure to deal with 4.3 signals. That's
necessarily Apple's problem.

But, as I said, that's not what bothers me. What bothers me is that I could
swear that it compiled fine under 1.1 _without_ adding in the set42sig() call
that I finally fixed it with. Also, there ought to be (and perhaps there is?)
a way to tell the compiler to fix that up for you, without messing with the
source. In fact, that's sort of what I expected the _SYSV_SOURCE define to do.
(Clearly, I'm not going to escape the man pages for much longer...)
