No worries, sometimes it is just like that. And you are not a jerk,  
because it is not your wheelhouse.
In parallel I am hitting the IBM OpenSource Community and got an  
answer that I find discouraging:

I admit, I do not understand what they are saying with 'gcc compiled symbols'.
Is here anyone who knows anything about that? And most preferably, how  
to make xlc or xlclang++ generate those symbols?

Kind regards
