runtime 'sizeof()'?

[Brandon Allbery]

As to the null pointer controversy, I've taken to using a derivative
of the technique Larry Wall uses in rn for all but the quick, sloppy
ultra-local (TRS-Xenix) programs:

#define Null(type) ((type *) 0)

...
	if ((fp = fopen(filename, "r")) == Null(FILE))
	    ...

You get the idea.  Easy to use and it makes the point (pun not intended)
evident.
