Initializes support for Panther's menu subsystemvoid sm_mncrinit6(void);
sm_mncrinit6is usually called automatically when you enable menus in your application. This function is called and menu support is enabled if you set
MENUSto 1 in the main function.
sm_mncrinit6sets a global variable to point to a control function. All screen manager functions that need menu support check the variable and, if it is non-zero, call indirectly with the request.
Call this function explicitly only if you write your own executive. You must call
sm_mncrinit6in the main function before the call to sm_initcrt.
