Well, I had it in hand, but I was reading the wrong section.
As I should be sensitive to from my time on the ANSI C committee,
appendices are not part of the standard, so the section that lists
the contents of signal.h is not a mandate.  In fact, it is not necessary
to define SIGCONT (or the other job control signals: SIGSTOP, SIGTSTP,
SIGTTIN, SIGTTOU) on systems that don't support job control.
