/* A macro to disable the copy constructor and assignment operator.
When building with C++11 and above, the methods are explicitly
deleted, causing a compile-time error if something tries to copy.
For C++03, this just declares the methods, causing a link-time
error if the methods end up called (assuming you don't
define them). For C++03, for best results, place the macro
under the private: access specifier, like this,
class name_lookup
{
private:
DISABLE_COPY_AND_ASSIGN (name_lookup);
};
