Sorry, I must be slow today, but I'm still not following.
Can you give an example of a strcpy use, where it's required
that the strcpy implementation must access its arguments
in a particular order? Because my understanding is that
there's no requirement that strcpy must operate left-to-right,
or anything like that.
