Probably that was not good idea to add them as globals for "C++" as demangling is not performed atm anyways
and that is unuseful.
I mostly tried here to obtain fully parseable result.
As far I understand since "C" is default, that will work for it now at least I think.
Not sure if there are scripts with extern "C" though. I dont think FreeBsd have.
