Caaame ooon... I'm not offended. What's wrong these days, people don't
have sense of humor anymore?

That's the reason I was asking explicitly for FreeBSD calling conventions. 
Remember, the code I'm talking about is a forth implementation
(self-modifying code) and I use a lot of SDL2 functions for portability.
That's why I think this is more likely a clang vs gcc issue.

Anyway thanks to both of you for your interest, I've been here for a few 
days only and you have made me feel on home already.
