Struct Error

Gcc 14.1 gives me an error compiling this code:
   struct vector;
   struct scenet;
   struct vector {
       double x;
       double y;
       double z;
   };
   struct scenet {
       struct vector center;
       double radius;
       struct scenet (*child)[];
   };
The error is:
   error: array type has incomplete element type 'struct scenet'
    struct scenet (*child)[];
                   ^~~~~
Is there any way to fix this, or is it not possible?
(This comes from generated code. Idiomatic C would use a T* here rather than T(*)[], but that is not an option. Other compilers like tcc, DMC and mine have no problem with it.)
