Ok. Perhaps change the message from:
fatal_error (input_location, "Output file %s should be removed "
+		 "in destination folder: %s", filename, out);

to 'output file %s already exists in folder %s' or something?  I.e report what 
the problem is, not what the solution might be -- after all, if the only 
solution is to delete the output file, why isn't gcov-tool doing that?
