As has already been noted, size_t is defined as the "unsigned integral type
of the result of the sizeof operator", i.e. unsigned int (at least in this
case).

I'm not sure how Turbo C handles the huge memory model, but I was interested
to read how Microsoft deals with it:  if you cast the result of a sizeof
operation on a huge array to unsigned long, the correct result is produced.

A similar extension allows you to cast the result of a pointer-difference
operation on huge pointers to long, and get the desired result.

i.e.
	char huge *p, *q;
	long size;
	...
	size = (long) ( p - q );
