typedef char bool;

[Martin v. Loewis]

> Do you know the compiler flag to turn off bool?

Thanks for your bug report. As I'm sure you'll agree, this is not a
bug in the compiler; it is a bug in your code - it is just not
well-formed C++.

Also, asking to turn it off sounds strange; you might just as well ask
to turn-off 'template', or 'class', or 'while'.

Of course, if you *really* need that feature, feel free to modify the
GCC source appropriately.
