Can't catch SIGCONT under 3.3.1?

[Ken Lalonde]

When following program is compiled with "cc test.c" under IRIX 3.3.1,
it prints "Caught SIGCONT", as expected:

	#include <signal.h>
	f()
	{
		printf("Caught SIGCONT\n");
	}
	main()
	{
		signal(SIGCONT, f);
		kill(0, SIGCONT);
	}

When compiled "cc -D_BSD_SIGNALS", it prints nothing.
The signal handler for SIGCONT isn't being called.

Bug?
