I gather that now all the library functions with pointer
arguments are declared like:
	void memcpy(noalias void *s1, noalias const void *s2);
Is that correct?

Now, I don't understand noalias very well, but I think
	void memcpy(noalias void *noalias s1, noalias const void *noalias s2);
would mean something.  What does it mean?
