Detailed Description

This header defines a macro CUOO_HCOBJ to put right after the opening brace of a hash-consed object struct:

 struct my_obj {
     CUOO_HCOBJ
     ... key fields ...
     ... value fields if present ...
 };

Note that there is no semicolon after the macro. A macro is used here, because the need for this field depends on the configuration.
