// Purpose:       Provide entry point for thread which then calls main()

// Description:   cyg_libc_invoke_main() is used as the entry point for

//                the thread object that is created to call the

//                user-supplied main() function. It sets up the arguments

//                (if any) and invokes exit() if main() returns

// Usage:
