This depends on the word size of your pointer and many people have
8-byte pointers these days.  Just say

	Instead of using a pointer that points at a constant string,
	just give name directly to the constant string; this way, we
	do not have to allocate a pointer variable in addition to
	the string we want to use.

or something.
