// Can use CVC4_UNDEFINED for things like undefined, private
// copy constructors. The advantage is that with CVC4_UNDEFINED,
// if something _does_ try to call the function, you get an error
// at the point of the call (rather than a link error later).
// CVC4_UNUSED is to mark something (e.g. local variable, function)
// as being _possibly_ unused, so that the compiler generates no
// warning about it. This might be the case for e.g. a variable
// only used in DEBUG builds.
