  | AFAIK we do have sig_t in <sys/signal.h>

Yes, but it isn't actually used anywhere (there).

I'd suggest that it should be.  More than once when trying
to remember the proper way to define a signal function I've done

	grep signal /usr/include/sys/signal.h

The result is not inspiring (though once the __P stuff goes away it
will be a bit better).   More importantly, neither that, nor the
current man page, reveal the existence of sig_t (you have to actually
go read signal.h in its entirety and pick the one line that matters).

Both should just use the type, since it is defined.
