I have a short L.S. C question:  I have a function which is defined
as:

  void myfun(x, y)
  register int x, y;
  {
	...stuff...
   }

   and I tried to make a function prototype for it like this:

   void myfun(register int x, register int y);


   and I got the error message "invalid storage class".  However when I 
   removed the word "register" from the prototype, it compiled.  What's the
   deal?  Why isn't "register" a  valid storage class?  (I only have v.2.01
   of the documentation, and this error message wasn't in it...).

   Is it because prototypes just check TYPES of variables, and "register"
   isn't a type, it's a storage class?  But then the error message doesn't
   seem to make sense.  

   Could someone please give me a clue?  :-)
