I don't think this matters here particularly, but in general I like to offer as
little as possible in an API, to keep as little constraint on the implementation
as possible.  Here you only need bool hasNonDefault() const.  Might want to
power it down?

Done.

     void printNonDefault(const char *fname = NULL) const;
     const char *configFileLocation() const;
     void possiblyDumpFile() const;
