"operator->" must be a no-argument member function, but G++ 1.31 (and 1.25)
seems to think it must have arguments.  (Frankly, I was expecting a "Sorry,
not implemented" message.)

All this on a vax running BSD 4.3, with tm.h and md linked to tm-vax.h and
vax.md.  The two patches posted on monday the 19th haven't been applied.

This code is based on the example in "The Evolution of C++: 1985 to 1987".
-------- opptr.cc -------------------------------------------------------------
struct Y { int m;};
class X {
    Y* p;
  public:
    Y* operator->();
    X() { p = 0;};
    };
Y* X::operator->() {
    if (p == 0) p = new Y;
    return p;
    };
main() {
    X an_x;
    an_x->m = 5;
    };
