Actually, you can't, since you can't pass a pointer to a variable
that has been defined with "register"...  But if you don't pass a
pointer, you can't swap arrays.  Therefore, you can't write a generic
swap function or macro.  (The FAQ may say something about this.)

My Publib function library has a anything-but-register-variables
swap function, of course. :-)
