 * This is a temporary function to do logging. It has wrong interface currently

 * places where logging should happen. When it is removed, compiler will do
 * our work of finding the places.
 *
 * The only thing it does is printing the dprogram prefix, message and
 * a newline if denabled is true.
 *
 * There are no tests for this function, since it is only temporary and
 * trivial. Tests will be written for the real logging framework when it is
 * created.
 *
 * It has the d in front of the name so it is unlikely anyone will create
 * a real logging function with the same name and the place wouldn't be found
 * as a compilation error.
 *
 * @param message The message to log. The real interface will probably have
 *     more parameters.
 * \param error_flag TODO
