As one of the authors of OpenH323 and PWLib, and as someone who has been
using this code for over 10 years, I think I am quite aware of what
projects they are used for. 

Given that your message was posted on the GM list, I assumed you were
talking in the context of GM. I had no way of knowing otherwise, until
you pointed this out.

The only thing I was thinking of telling you is that your
confrontational approach is not conducive to elciting an answer. But I
am sure you will learn that eventually anyway.

Reading between the lines, I can see now what your actual problem is.
You want to run GnuGk and GM on the same machine, but incompatibilities
in the way the PWlib and OpenH323 are compiled for these two programs
will prevent the same shared libraries being used for both programs.

This is a legitimate problem and one that will be addressed in the
future.

Yes, I fully realise that dynamic casting is part of the ANSI C++
standard. Your assumption is that every C++ compiler complies to the
standard, and always has. We've been using PWLib on various platforms
since 1991, before ANSI C++ was even invented.

Thank you for sharing your opinion.
