If you had read the damn standard, you would have known that the others are all about arithmetic types, 
structs and unions, pointer to void, and conversion to `bool`, and apparently they do not apply. Pity.

Because you are writing C, you don't need to cast the pointer to `struct zzz const * const * const`; you 
just cast to `void*`. If you don't know that, you cannot know more C than me.

I'm already very disappointed about this thread, because half of the messages are about `char **` does 
not implicit convert to `const char **` which is technically a different question from yours. And now I'm 
getting more, because of your disrespect.

You are in no position to say that. We are well educated, and apparently you are not such a person.
