There is nothing wrong with your program, except that you chose some
very unlucky names for your enum and its members.

The ANSI committee has added a new boolean type to the C++ language.
The type is called "bool" and it can take on two values: "true" and
"false".  Thus "bool", "true", and "false" are now keywords.  This was
implemented in g++ starting with version 2.6.0.

If you will, for example, change:

    bool  to Bool
    true  to True
    false to False

in your program, it will work fine.  (Or, just delete the first line of
your program, and it will use the built-in boolean type.)

Somebody else replied that you must put "enum" in front of

    bool foo = false;

That is not correct.  In C++, you can (and should, stylistically speaking)
simply use the enum, struct, or union tag all by itself.
