Howdy Davide!

The C++ comments on IBM compilers is something that comes up in every release. 
Seems like I just can't get programmers here to stop using C++ style comments. 
We might have to explore shock collar technology for this. I will keep working 
on a way of incorporating such tests into our night build/test cycle. 

Thanks,

Ed
