Is this a function or a structure???(once again, a mind-boggling example from Kernighan)

No, he is defining a function 'makepoint' that returns a value of type
'struct point'.
'struct point' is presumably defined at some earlier point.

(At a guess 'struct point' is defined as:

  struct point
   {
   int x;
   int y;
   };

Such a definition would at least be reasonable, and consistent wwith
the usage of 'struct point' in the function 'makepoint')
