Are you sure of this? I sometimes write:
	
	foo (ap) register float (*ap)[4][4]; {... (*ap)[0][0] = 33; ...}

I do this because my compiler (DEC/Vms) ends up making slightly better
use of registers than if I wrote:

	foo (array) float array[4][4]; {... array[0][0] = 33; ...}

(and because it's slightly more pleasing to my brain actually to say "pointer-
to-array" if that's what I'm thinking of). Are you saying my syntax is legal
only by the grace of DEC?
