[Q] compiler no longer warning about undeclared struct?

[Guennadi Liakhovetski]

Hi

I just ran across a driver in the kernel (drivers/media/video/ov2640.c, 
struct ov2640_priv::info), that does something like

struct xx {
	struct yy *y;
};

static void z(void)
{
	struct xx *x;
	void *p;

	x = ...;
	p = ...;
	x->y = p;
}

where "struct yy" is nowhere declared, and the compiler happily swallows 
this... Shouldn't it complain? Didn't it complain before?

Thanks
Guennadi
