Cool little library you got there Dan, can you add support for the "cdcel"
calling convention, and port it for Linux/FreeBSD? Because I have "zero"
understanding of machine level coding with Euphoria, I cannot finish this myself.
Nevertheless this little library could be very useful to me in various cases, and
I'm ready to vote for it upon completion. .

Vincent
