[Coco] OS9 C compiler

[James Jones]

cstart is the code that sets up things that C programs expect (zeroing or
initializing file scope and static variables, setting up stdio for standard
in/out/error, converting what the target OS uses for command line arguments
into argc/argv), calls main, and then does whatever teardown C programs
expect (e.g. closing standard input, output, error, for ANSI calling
functions registered with atexit()) and exits the process, passing the exit
code returned from main() or passed to exit() back to the operating system
so the parent process can see how things turned out..

The important part here is that it calls main(). That's the reference that
isn't resolved. Whoever wrote the code didn't include main(), which a
complete C program has to have. Maybe whoever wrote the code intended it to
be used as a library?
