I got a solution, even though it is not the best:

Before I trace anything, I check the filename and I don't 
trace, if I am either in a file with absolute (not 
relative) pathname or if i am in the tracer declaration:

int line;
Opencxx::Ptree* fname
  (env->GetLineNumber
   (Opencxx::PtreeUtil::First(body), line));
if (std::string(fname->ToString()).find('/')==0 ||
    std::string(fname->ToString())=="fntrace.hxx")
  return false;

Any idea for a better solution?

Ok, to make it Windoze compatible, the "find" should 
probably be changed to: find_first_of("/\\") and "fname" 
could be instanciated as std::string instead of converting 
it twice, but besides of minor enhancement, is there a 
better, totally different approach?
