It is completely right that the compiler doesn't recognise the language 
of pu.h. The problem is that the application IS indeed written in C++ 
and has been compiled using g++-3.3 without any problems as long as I 
don't include the header pu.h.

Sure, here it is (though only the first few lines because the problem 
becomes evident and the whole takes up about ten pages...

I would be most grateful for any suggestions. Thanks again,
