Thanks for your suggestion.

How did you get this error message? It is different from mine.
Each array element is initialised by five values that were not flagged with
errors before my source code refactoring. Well, I'm sorry - The initialisation
list was too long for me to remember that I updated the data type for two other
global variables that were referenced from the included source file "sipp.hpp".
The message did not point me to my error directly. I suggest to improve the
wording from "an entity" to "entity 'data'" in my use case.
struct sipp_option {
const char *option;
const char *help;
int type;
void *data;
int pass;
};

The specification "void const* data;" would be another design option. It might
not be clear yet which way will be preferred for the concrete application.
