This is not the behavior I see on an HP 9000/800 running HP-UX A.B7.00.
If I say:

	@test = `./a.out`;
	print "Out: @test";

where a.out is the simple C program:

	main()
	{
		printf("Hello, ");
		fprintf(stderr, "world.\n");
	}

I get:

	% perl backticktest
	world.
	Out: Hello, 

Because of this, I've written a subroutine to capture both the standard
output and error and return it in a list.
