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')
