[Coco] Microware C Compiler port

[Bill Barnes]

Hmmm, I thought it was this way:   printf("long int: %l",longint);
I do know that using "%d" deals with an int though, never seen it referenced as "%ld"

As far as length.... compiler specific. only guarantees is long is not smaller than an int, and int is not shorter than a short. I forget the OS-9 C (CoCo) lengths, and don't feel like chasing down my manual.
