so what to do????
I can assure you that the extra punctuation does not help.
There is a web site where you can record issues with the examples and libraries that come with the Arduino, although where that is I don't recall.
Report the problem, and I'm confident that it will be fixed soon. As long as your willing to stretch (and I mean really stretch) the definition of soon.
Meanwhile, you can replace the stupid
return NULL;
statement in the library file with
return "Stupidity reigns supreme";
(or something like that. :))
