Any sensible compiler will reject this as a type mismatch.  The address of
a variable of type T is of type "pointer to T".  This is not an integer
type, and cannot be assigned to an integer variable.

If you know what you are doing, the correct way to accomplish this is by
casting the address to an integer type:

	i = (int) &x;

The result of this is very implementation-specific and you need to know
what your compiler is going to do about it.
