Bennugd Void * Issues As Type Members And Function Return Types

    I've recently started looking at BennuGD and got to the point where it would be convenient to have a linked list. So, I've tried to implement a generic linked list using void * for the stored items but this has led to a couple of issues.

    Firstly, I couldn't get the code to compile with a type containing a void * element but I managed to work around this by first defining a type containing nothing by a void element. I have no idea why this worked and since the compiler error was a syntax / parsing error I can think of no good reason why this should work :S.

    Secondly, I have not managed to successfully compile code that contains a function that returns a void * and I've tried an analogous work around to the above, defining a function returning type void, but that didn't work. Currently I'm working around this by returning an int * and doing some nasty type cast mangling but I don't think I should need to do this.

    Has anyone else run into similar issues to these?

    Which compiler are you using? I compiled a small example with gcc 4.7.2 and had no issues:
    class CTest
      : m_number(0),
      int m_number;
      void* m_pointer;
    void* MyFun(int i)
      return 0;
    int main (int argc, char* argv[])
      CTest myTest;
      return 0;
    Can you give a minimum example that doesn't work for you?
