No good: the dpANS does not say that data pointers are the same `size'
as function pointers, and indeed, on (e.g.) the Univac 1100 series, as
I understand it, data pointers are 2 words while function pointers are
18 words.  Hence stuffing a function pointer into a data pointer will
lose information.  The dpANS *does* guarantee that pointers to functions
are all the same `size' (I think), so:

	typedef void (*(*NextStateFun)())();

and go from there.
