Empty structures have sizeof(1) in C++ now ?

Is this a bug ?


	critter phk> cat /tmp/_.c

	#include <stdio.h>
	struct foo {
	};

	int
	main(int argc, char **argv)
	{
		struct foo bar;
		printf("%jd %jd\n", sizeof(struct foo), sizeof(bar));
		return (0);
	}
	critter phk> cc -o /tmp/a.out /tmp/_.c
	critter phk> /tmp/a.out
	0 0
	critter phk> c++ -o /tmp/a.out /tmp/_.c
	c++: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Wdeprecated]
	critter phk> /tmp/a.out
	1 1
