g++ 1.35.1- complains that it must do a bitwise copy on a class with a
member with an operator=().  But the class doesn't have any members at all!
----- g++-op=.c -----
class string {
    friend class strsub;
  public:
    strsub operator()( short p, short l);
    };

class strsub {
    friend class string;
    strsub( string&, short, short);
  public:
    string& operator=(string&);
    };

strsub string::operator()( short pos, short len) {
    strsub sub( *this, pos, len);
    return sub;
    };
