I don't have time to review it right now. Sometimes, these warnings with C types can be tricky, because fixing them on one platform can cause additional warnings on another.

Did you just see these warnings on those example programs? And not on the main library?

BTW, I tried emailing you (in reply to the email you sent), but your mail server rejected my email - just letting you know that your mail server is actively preventing others from communicating with you.
