You definitely have to have IO since it is using the console
driver.  If the console driver is using termios, it also needs
the Classic API semaphore manager.

In 4.7, the Classic API semaphore manager was required in
all applications.  Now it is optional.  So is the region manager.

Making this change resulted in a number of cases where the
optional managers line was wrong.  I have fixed the examples
in CVS.

Thanks for testing this.
