Fixed, thanks.

Hmm.  I've removed them because I got warnings from the GNU C++
compiler.  For both g++ 3.0.1 and 2.95.3, a `friend' declaration is
sufficient.  Code like this:

  void end_diversions();

  class diversion {
    friend void do_divert(int append, int boxing);
    friend void end_diversions();

produces a warning about declaring `end_diversions' twice.  Is
somebody on the list who knows the C++ standard well enough to decide
whether this is a feature of g++ or whether this really conforms to
ANSI C++?
