Sorry, I realize that this doesn't really address the point.
In addition to that union, we should also have a particular mechanism to compute
what the proper offset should be between the PyGC_Head and the PyObject.
Probably something like:
typedef struct {
PyGC_Head head;
union {
/* ... similar union as in PyGC_head */
} body;
} _PyGC_dummy;
#define _PyGC_Head_OFFSET offsetof(_PyGC_dummy, body)
#define _Py_AS_GC(o) ((PyGC_Head *) ((void *)(o) - _PyGC_Head_OFFSET))
Regards
Antoine.
