This is a bug report for RHIDE Version 1.4.7.6 (Apr 14 2000 18:44:41)
I am running MS-DOS 7.10

My problem is the following:
============================

 

In trying to compile the following simple program which uses an array
of method pointers -

 

*********************************************************************
*PROGRAM
*********************************************************************

 

#include <iostream>

 

enum BOOL {FALSE, TRUE};

 

class Dog
{
   public:
      void Speak() const {cout << "Woof!\n";}
      void Move() const {cout << "Walking to heel...\n";}
      void Eat() const {cout << "Gobbling food...\n";}
      void Growl() const {cout << "Grrrrrrr\n";}
      void Whimper() const {cout << "Whining noises...\n";}
      void RollOver() const {cout << "Rolling over...\n";}
      void PlayDead() const {cout << "Is this the end of Caesar?\n";}
};

 

typedef void (Dog::*PDF)() const;

 

int main()
{
   const int max_funcs = 7;

 

   PDF dog_functions[max_funcs] =
       { Dog::Speak,
         Dog::Move,
         Dog::Eat,
         Dog::Growl,
         Dog::Whimper,
         Dog::RollOver,
         Dog::PlayDead
       };                  // this is line 33 where the
                           // compiler flags the error.

 

   Dog *pDog;
   int Method;

 

   while(1)
   {
      cout << "Choose - " << endl;
      cout << "\t(0) Quit;" << endl;
      cout << "\t(1) Speak;" << endl;
      cout << "\t(2) Move;" << endl;
      cout << "\t(3) Eat;" << endl;
      cout << "\t(4) Growl;" << endl;
      cout << "\t(5) Whimper;" << endl;
      cout << "\t(6) Roll Over;" << endl;
      cout << "\t(7) Play Dead;" << endl;
      cout << "\t\t\t: ";

 

      cin >> Method;
      if(Method == 0 || Method > 7)
         break;
      else
      {
         pDog = new Dog;
         (pDog->*dog_functions[Method - 1])();
         delete pDog;
      }
   }

 

   return 0;
}

*********************************************************************

 

... I recieve the following error messages, although it nevertheless
compiles fine using Borland C++ Compiler 5.5.
