Martin,

thanks for the quick and helpful answer. However, I thing this was a 
very unfortunate decision: New semantics should have used a new name.
I have some real trouble converting thinks like
``char foo[] = __FILE__ "/" __FUNCTION__;''
It seems I must write a C++ class with a constructor now, because 
string concatenation in initialization will not work any longer.

As a side-note: What is the correct preprocessor GNUC minor version 
to detect "egcs 1.0"? Maybe I want to use the older compiler...

Regards,
Ulrich
