Uh, I think you have this backward.  Passing a struct to a function is
done by value in modern C.  Back before this feature was introduced,
some compilers would implicitly turn a struct name into a pointer to
that struct, as still happens for arrays.  Some such compilers did
grumble about &array, and may well have done the same about &struct
(I don't remember for sure).
