+// 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:
