I think enum is oversold by some people (not me). C Compilers won't
do much when you use them interchangeably with int, simply because
they are designed to be used that way, no?
If existing code used 0 as false and 1 as true, and it learns an
"auto" value with a new definition,
#define TRISTATE_AUTO 2
without TRISTATE_{TRUE,FALSE} defined to 0 and 1, that would be a
good place to stop. I'd be quite happy with that.
