Overloaded operators, friend functions or member functions, certainly can
take non-const references to objects as arguments.

His problem is more fundamental than this.  I suspect he's doing something
like including the friend keyword when defining the friend function,
rather than when declaring it.

He'll have to post a short snippet of the example code, including the
error and which line it's on, to get more help.
